A Modern-Day “Roman” Aqueduct For Florida
A Modern-Day “Roman” Aqueduct For Florida
The west coast of Florida remains trapped in an ongoing drought. In Pinellas and Hillsborough Counties (Tampa and St. Petersburg/Clearwater) severe restrictions on water use are in place. Even the use of reclaimed water for lawns and gardens is now restricted. The rainy season is not yet here; but in past years the amount of rainfall received during the wet months was far below the historical average, so that reservoirs and ground water supplies have never had a chance to recover.
The situation is quite different in northern Florida, in the Panhandle and all across the State close to the Georgia border. The weather in those parts of the State is generally wetter, and more consistently so, than the weather farther south.
Yesterday, our local St. Petersburg Times carried a story (with photographs) of the damage which is now being inflicted in Madison County (which borders Georgia) by floodwaters from the Withlacoochee and Suwannee Rivers. The storms which produced the rain moved from west to east across the Panhandle over the past week, to the point at which the Withlacoochee crested at 89 feet, four feet above the record set in 1948. So far, the rising floodwaters have destroyed or caused severe damage to almost 200 homes and lesser damage to 500 more, all areas combined. Two people are known dead, and one person is missing.
Quite apart from the possibility of reducing the tally of deaths, personal injury, and property damage which even a partial remedy for river flooding in these areas might entail, it boggles the mind just to consider the sheer waste of so much fresh water. Most of that damaging flood water will be gone forever as it eventually finds its way to the Gulf of Mexico. That’s a shame, because so much of it could be put to good use in the west coast, central, and other parts of the State where it is so desperately needed. The waste is not just limited to damaging flood waters, either. The “top of Florida” is blessed with more rainfall, on average, than it needs. Obviously, the flow of river water into the Gulf represents a volume of water which has not been put to good use.
In passing, we acknowledge that the flow of a certain amount of river water into the Gulf is said to be necessary for the health of the shellfish beds near the coastline.
Even so, it seems inadmissible to stand by and do nothing but watch a surfeit of water in the northern counties lay waste and then go to waste while there is such a great need for water in other areas of the State. Surely there is a partial remedy which might ameliorate the problems in the affected sections.
The Romans found a way to move big volumes of water over considerable distances. Surely we can build on their success – and on successes over the centuries since that time – by constructing an Aqueduct system to bring excess water from the northern Florida counties to drier areas to the south.
The best part is that the right-of-way is already in place! It’s called Interstate 10 and Interstate 75. Take a peek at a map of Florida. Find the intersection of I-10 and I-75. The Suwannee and Withlacoochee Rivers are close by, as are other rivers. There are others to the west, and I-10 probably crosses every one of them.
Excess water could be fed into the Aqueduct lying above-ground or underground in the median of I-10 at various points along its route, and then fed south toward Tampa and St. Petersburg/Clearwater in that part of the Aqueduct lying within the median of I-75 and I-275. Do you see how obvious that is?
If ever there was a perfectly-planned right-of-way for a particular purpose, although not part of the design at the outset, this is it.
There would be hurdles. There always are. Will and determination were invented for the purpose of overcoming hurdles.
It seems to me that the construction and operation of The Florida Aqueduct is an undertaking which private capital should undertake. It need not cost the State a penny.
Let’s see whether anyone steps up to the plate.

The flammability point of biodiesel.
I’ve mentioned that it’s biodegradable that it’s safe to use blah, blah, blah, all these different things, but I want to show you how safe this is. This biodiesel, I’ve made from canola oil, so I’m going to pour a little bit in here, and now it’s time to play with fire. We’re going to come down here. Light up our torch, notice I have my fire extinguisher people.
We now have a nice blow torch going. Notice I’ve got some nice biodiesel on the ground here. I want to show you that biodiesel is very, very safe to have around. I can’t light it on fire. This torch is a really hot torch. I’m actually using map gas. Map gas actually has a higher flame temperature. So I’m just trying to light this sucker on fire, and you know what, she’s not going. That’s because biodiesel isn’t actually that flammable. It has a much higher flash point than normal diesel, and I’ve just proven it.
And that’s one of the reasons people like biodiesel is because it’s so safe to use. In fact, if this stuff spills on the ground the MSDS and things that it calls for is get a garden hose and wash it off. It’s not going to light up. It’s as safe to have around as vegetable oil. No I have to cavy up that this biodiesel has been cleaned. We have got all the methanol out of it, and we’ll talk a little bit about that later, but I just want to show you that it’s very clean and it just doesn’t burn. That’s that little fun experiment. We want to show you that biodiesel will burn though. When it’s under pressure it does burn quite well. For this experiment I’m just going to start a fire, and I’m going to spray it into it. As you can see it will burn, so when it’s in your diesel and it becomes injected, it will burn beautifully. That’s biodiesel burning.

Unless you have been trapped in a cave for the last seven months you are well aware of the disaster overtaking the American automobile industry. Our government is using billions of taxpayer’s dollars to prop up an industry that has been one of the leading facilitators of numerous ills in our society, which will also take billions of dollars to repair, if it is even possible to do so. Air pollution which contributes to increased medical costs, urban sprawl, a negative balance of payments from importing oil and global warming can all be traced at least in part to our addiction to the automobile. Now that I’ve ranted about the autos effect upon our society I also greatly acknowledge that we all, myself included, greatly enjoy the mobility and freedom provided by the pernicious machine. We can’t live with ‘em and we can’t live without ‘em. What are we to do? A lot has been written about the currently nonexistent plug-in electric car. This machine when it finally hits the market could help solve some of our problems but current pricing estimates place the car in the forty thousand dollar range. I’m sure of one thing, it won’t solve many problems if you don’t sell them and at that price I’d hedge my bets. However, there is one personal transportation option on the market that fits into all of President Obama’s initiatives for energy self sufficiency, global warming (reduction of green house gases), health care (exercise and weight loss), environmental protection (reduction of air and water pollution), and infrastructure renewal. That option is the Electric Bicycle. The electric bike using lithium batteries (traditional lead-acid is very environmentally harmful) can go, depending on load factors and riding habits, roughly twenty miles at twenty miles an hour on one charge. It is almost completely silent, gives off no emissions, does not use foreign oil, does not require much room to operate or park, never needs a tune up and provides exercise. It eliminates many of the drawbacks of riding a traditional bicycle for basic transportation while having few of its own. I recognize that not many of us are hardy enough to ride a bike in the rain, snow or freezing cold but that applies as well to motorcycles, motor scooters and traditional bicycles. The electric bike can get you farther, faster without arriving at your destination soaked in sweat. It can operate in many places where other motorized vehicles cannot and makes taking hills a cinch. Riding five or ten miles to work is no big deal and you can simply pedal around bottled up traffic. Usually the lightweight batteries easily detach from the bike and can be carried into your place of work or school for recharging. Some electric bicycles offer high tech extras such as LiFePO4 batteries that are good for a thousand recharges, regenerative braking that helps recharge the battery much as a Prius does, and internal gearing to generate more torque for uphill climbs. Most electric bikes use what is referred to as a hub motor. This is not a traditional gear or belt-drive motor but is built directly into the hub of one of the wheels. This motor contains two internal rings of opposing magnets that when power is applied causes the wheel to spin. Such motors need little service and never require oil changes, spark plugs or new belts. Electric bikes come in several of styles. There are the traditional “beach cruiser” and mountain bike styles as well as electric folding bikes, tricycles and “road bikes”. The electric folding bikes are particularly interesting. Smaller and lighter than a traditional bicycle, they easily fold up and fit into a car trunk and can be carried on a commuter or subway train with little effort. You can take the train to your stop, unfold the bike and pedal on your way. They are also useful for those who live in tight quarters and have no external place to store their ride. For those of you that are moderately handy with tools, there are a number of electric bike kits on the market that allow you to adapt an ordinary bicycle into an electric bike. One company, Worldwide Electric Bikes, has a particularly well-designed kit that has many of the features I previously mentioned. These electric bike kits do not require a high level of mechanical ability to install. A few common hand tools, a basic understanding of how things go together and the ability to read directions is all that is required. However, if you don’t know the difference between a crescent and a hex wrench, you may wish to buy a pre-made bike or have someone install the kit for you. If you do choose to go the kit route, you can end up with a much more powerful and sophisticated bike for substantially less money than a factory built electric bike. Electric Bicycles in all forms have long been a staple of personal transportation in Europe and Asia where there are hundreds of thousands in operation. In the United States bicycles have traditionally been dominated by the toy or recreation market or for the dedicated enthusiast. In both Europe and Asia, cycling has been a traditional means of basic transportation. I believe that this is going to be more and more the case in this country. People are avidly seeking relief from the high financial and societal cost of automobiles. The electric bicycle, while not a panacea, is definitely poised to help provide a portion of that relief. Electric Bicycles are inexpensive to purchase, require no license or insurance, have a negligible cost of operation and are totally “green”. So, what’s not to like? http://www.worldwideelectricbikes.com

No Bailouts Necessary: Green Transportation

Genetically modified (GM) foods are not being found to be safe for humans, or for the environment. There are a number of reasons why there a growing number of people are against GM foods. Are Genetically Modified Foods Safe? The reason to resist the growth of GM food in our diet is that it has a negative impact on our environment; plants and animals grown organically are not distorting their genetic makeup. And in the rush to accelerate the production of genetically modified foods, scientists are short cutting testing methods. Recently, the United States Tufts University, School of Medicine was involved in testing the effects of genetically modified rice directly on children (by-passing the usual practice of testing on animals). This direct testing on children created controversy and a formal letter of protest from 22 international scientists to the University; the protest letter has been made public through various social media. The problem with genetically modified foods is that there is also a reaction for the action; unfortunately, globally, in our rush to grow food supplies, we have not taken the time to properly test and research the long term impacts and effects of genetically modified foods. It is easy to be against GM foods - our planet is at risk. To read more about genetically modified foods and the healthy alternative – organic foods, please visit Is Organic Food Better?

GM Foods Against
The letter protested the use of children as a breach of medical ethics code since children cannot legally give their consent (since it is not deemed to be informed consent) to participate in experiments. As Professor David Schubert, Salk Institute of Biological Studies said, “…it is completely immoral to feed this rice to children without proper safety testing … [i]t’s like putting a new drug on the market with no toxicology or safety trials”.
In defense of their position, the Golden Rice Organization issued a press release that states they “…us[ed] the correct Chinese and US government approved processes, the trials in China went ahead last year with the formal approval of their parents and the understanding of the children”. How do children understand the impact of genetically modified food on themselves or the environment? It’s a complex subject that many adults have a hard time understanding. Also, how can anyone (parents, children, or testing scientists) understand what the long term effects of genetically modified “golden rice” are on the human body without prior study or testing?
More importantly, will the overall risks of genetically modified foods over time out weigh the alleged benefits? Farmers have cross-bred plants and animals for hundreds of years to improve their products. Improvements to size, produce yield, taste, hardiness have been achieved through relatively natural means and within nature’s own boundaries; different species were not bred together.
With the discovery of DNA and a method of gene extraction, the concept of genetic modification was born. The intent of genetic modification is to create food that grows quickly, yields much, is resistant to pests, to disease, and to other natural events. However a number of scientists respond that the benefits are not worth the risks; genetically modified foods often become resistant to herbicides and pesticides requiring ever increasing amounts. There is the suspicion (still unproven) that pollinating bees have been affected by the increasing use of these chemicals and that both pollinator and predator species have been affected by the genetically modified crops (also known as transgenic crops) through habitat destruction and use of dangerous herbicides and pesticides.
Since the introduction of genetically modified foods, some scientists are reporting that food-related illness has increased. The only published human feeding study confirmed that genetic material in genetically modified soy transferred into the DNA of intestinal bacteria and continued to function. What long term impact will these foods have on the population and the environment? There are many more potential risks in the development of genetically modified foods. Animals that were fed genetically modified feed appeared to suffer from increases in fetal death, low birth weight, sterility, and more. The concern is that human reproductive failure and sterility or infertility will be long term consequences to using GM foods.
In the US, the Department of Agriculture reports that cotton and corn crops have been genetically modified to produce their own Bt toxins since 1996. Bt modified crops are insecticidal crystal proteins and are considered effective against crop-damaging caterpillars. The toxins are considered important for pest control and since resistance to herbicides and pesticides is growing, the sentiment is that these genetically engineered Bt toxins will help to protect the crops. The issue with the GM Bt toxins is that they are considered serious allergens; ever wonder why so many more children and adults are exhibiting allergic reactions than ever before?

Recycling – What it Really Is
Recycling – What it Really Is
Recycling has become the catch all phrase often used in place of the 3 R’s. But in its truest form recycling means taking one thing and changing it, usually chemically, into another. This is not to say that recycling is without value; it is certainly better than putting the items in the bin where they will end up in landfills and leach chemicals into our ground water. It is though to say that before you place anything in the recycle bag, first consider if you could reduce or re-use it, because everything that ends up in the recycling bag will have to be altered before it can be used again. Even then it is cleaner to produce goods from recyclables than from raw materials.
Here are just a few reasons to make certain that after you have reduced the amount of waste your create and re-used as many things as possible that your family puts as many things as possible into the recycling bins:
- Recycling one aluminium can saves enough energy to run a TV for three hours — or the equivalent of a half a gallon of gasoline.
- Each ton (2000 pounds) of recycled paper can save 17 trees, 380 gallons of oil, three cubic yards of landfill space, 4000 kilowatts of energy, and 7000 gallons of water. This represents a 64% energy savings, a 58% water savings, and 60 pounds less of air pollution!
- The 17 trees saved (above) can absorb a total of 250 pounds of carbon dioxide from the air each year. Burning that same ton of paper would create 1500 pounds of carbon dioxide.
- Recycling plastic saves twice as much energy as burning it in an incinerator.
- The energy saved from recycling one glass bottle can run a 100-watt light bulb for four hours. It also causes 20% less air pollution and 50% less water pollution than when a new bottle is made from raw materials.
- A modern glass bottle would take 4000 years or more to decompose — and even longer if it’s in the landfill.
Today is the actually a great day to talk about recycling. Each Thursday the council sends around men to collect our recyclables. The council gives us re-usable sacks, which we can use to collect all paper, cardboard, tin cans, aluminium, glass bottles and jars and plastic bottles. Unfortunately, they do not over recycling for other plastics. As I have been writing this series of blogs that has been one thing that I have been especially mindful of: how much plastic packaging manufacturers use that cannot be recycled and that it is estimated takes over 500 years to decompose in landfills.
But it is not just our plastics, glass, metals and paper that we recycle. Thanks to a wonderful programme through the Islington council, last year we were able to purchase a subsidized wormery to recycle our food waste into compost and liquid fertilizer for growing my own food. Actually, even though we may think that food thrown into the bin will degrade relatively quickly in the landfills, the biggest problem is the amount of methane, a dangerous green house gas, which it produces in that time. Methane is twenty times more potent than carbon dioxide and a major contribute to climate change. While my wormery cannot accommodate meat products I put all peels and unused fruits and vegetables into it. I should soon be harvesting my first patch of compost…just in time for my summer garden.
So how does my family do on recycling? Not too bad honestly. This week we had two bags of recyables and will only have two half full 13 gallon bin bags of other rubbish. Actually hubby and I got into a minor disagreement over the trash last night. One of the first rules of the 3R’s is to only throw out your garbage when the bag is full. In our case though, it had begun to smell. I am still looking for a solution…if anyone has ideas they would be greatly appreciated. But for a family of three adults and one pre-schoolers two large bags of recycling and one full 13 gallon bin bag in a week is pretty good I think. I imagine that there are single people, who put more than one bag in the bin each week.
Terri O’Neale is the mother of six; ranging in age from 3 to 22. She has been both a working and stay-at-home mother at various times in her life.

We’ve certainly seen quite a few companies come out and say that their manufacturing facilities have a zero impact on the environment, meaning zero footprint, but indeed, there is much controversy on how to determine what a zero foot print is. It’s almost impossible to get to zero, even if a company goes and plants 10,000 trees over the course of 5-years. The other day at a Think Tank meeting, we were talking about how to establish a complete CO2 discharge chain of a product, including all its components in the process of making it. From the wrappers, card board box, printing, assembly, energy to do all that, the distance the people traveled to work in what type of cars, etc. I mean really narrowing down the actual discharges. Not because we are Global Warming alarmists, but because we feel it is not exactly correct for a company to claim Zero Emissions. And that we must have a more realistic view of the total process, Supply chain and all. Many companies like Dell in Texas have stated that they have finally achieved zero emissions, but they were attacked for stating that, why? Because, everyone has a different concept of what nothing is. In other words we are all out there fighting over nothing and that makes no sense to anyone, no matter how you figure it. Indeed, we should be applauding Dell for their solar panels, LEEDs certified warehouses and assembly plant and all their hard work and meaningful dedication to do the right thing. And yet, we are not doing that are we? Instead we find people attacking businesses, even those that go out of their way, spending millions of dollars to do the right thing. I ask are we doing the right thing by allowing persnickety environmental complainers to attack America’s greatest companies? Lance Winslow – Lance Winslow’s Bio.

CO2 Footprint of a Product

Green and Clean Computing Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects. The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally. There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life. The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary. The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance. Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment. Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.

Cheap Flights and Climate Change
What can be done about this increasingly worrying contribution to global warming?
The most important options to reduce aircraft CO2 emissions are:
Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.
But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **
On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).
Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…
Furthermore the relationship between the costs and the environmental externalities (i.e. costs not included in the economy like health damages caused by pollution) needs to be considered as well: there are higher marginal impacts for short-distance flights that should be considered in prices paid by passengers.
All these political, technological and personal choices are some of the good examples needed by the developing countries to follow the 21st century’s Western society along a new sustainable path which looks like the only good alternative forward.

Antarctic Peninsula Climate – A Change in Krill Ecosystem
Antarctic Peninsula Climate – A Change in Krill Ecosystem
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.
