When they discovered a new parasite in water fleas a couple of years ago, they classified this undescribed species as a microsporidium, mostly because it possessed the unique harpoon - like infection apparatus (the polar - tube), one of the hallmarks of microsporidia.

Kevin Costner stars as the enigmatic drifter known only as «the Mariner», at a time when the world has been covered with water from the melted polar icecaps.

Common to all variations of the breed is an unmistakable sound that didn't change dramatically when the air - cooled boxer was replaced by the water - cooled engine in late 1997; a less - than - ideal weight distribution combined with a high polar moment of inertia; compromised packaging with little room for luggage; and a driving experience dominated by phenomenal grip and traction — while it lasted.

It's been clear for a long time that, other things being equal, polar bears have a much easier time when Arctic waters are sheathed in ice to provide a platform from which to hunt and kill seals.

I found stories about 4 polar bears that drowned in a storm and stories about 2 that were killed by scientists studying them when the scientists tranquilized the bears and the bears made their way back into the water and drowned.

Over all, open water has spread in the Arctic this summer nearly as much as it did last summer, when polar experts said the ice cap shrank far more than had been measured since satellites started scanning the region 30 years ago — and probably more than it had shrunk in a century or more.

«Every summer when the sun melts the surface the water has to go someplace, so it accumulates in these ponds,» said Jamie Morison, a polar scientist at the UW Applied Physics Laboratory and principal investigator since 2000 of the North Pole Environmental Observatory.

Sea ice is critical for polar marine ecosystems in at least two important ways: (1) it provides a habitat for photosynthetic algae and nursery ground for invertebrates and fish during times when the water column does not support phytoplankton growth; and (2) as the ice melts, releasing organisms into the surface water [3], a shallow mixed layer forms which fosters large ice - edge blooms important to the overall productivity of polar seas.

Also... Not discussed in the article... As polar ice becomes greatly reduced, oceans will likely warm much more rapidly (similar to what happens when ice in a glass of water becomes minimal).

When cold, dense water of the polar regions sinks and flows beneath warmer ocean water.

So when you transport enormous amounts of warm tropical waters to the poles for about 400,000 years, you end up with ice ages, which after a while may shut down the MOC again, further increasing the polar cooling, as for instance happened at the Younger Dryas.

Sea level rise is caused by the melting of polar ice caps and the expansion of water when it is warmed, both triggered by global warming.

When oceans get cold, and the surface of polar waters freezes, it snows much less and the sun takes away ice and limites the lower bound of temperature and sea level.

The schematic below from Mangerud and Svendsen shows the warm water incursions from the Atlantic flowing past the west coast of Svalbard at about 11 thousand years ago, when the Laurentide Ice Sheet still covered the eastern half of Canada and the northern US, excluding fish, seals and polar bears from most of Canadian Arctic and Hudson Bay.

Thoughts on Antarctic Sea Ice In warm times, when southern polar waters are warm and the ice around the Antarctic continent is small, the snow falls on the ice on land and builds up.

When the convective processes of the atmosphere remove enough water vapor from the oceans to drop sea levels and build polar ice caps, as has happened many times before, the top 35 meters of the oceans where climate models assume the only thermal mixing occurs, must heat up cold ocean water that comes from depths below the original 35 meter depth, removing vast more amounts of heat from the earth's surface and atmosphere.

In cold times, when southern polar waters are cold and the ice around the Antarctic continent is large, the snow falls on the ice shelves and does not feed the ice on land.

[1975] Greenland, which is a small Antarctica, a polar landmass entirely surrounded by water, has an ocean to the south that remains as a vapor reservoir even when the ocean to the north freezes, so it retains its ice cap.

They based their findings on analysis of the chemical isotopes locked in ancient ice from the Weddell Sea embayment, and the evidence suggests that in the past, when polar waters became more stratified, the ice sheets melted much more quickly.

The presence of this warm water in the North Atlantic helps explain why Scotland has a relatively mild climate when compared to places at similar latitudes in North America such as Churchill, Manitoba — a Canadian town famous for its seasonal polar bear population.
