Discussions about the consequences of the vanishing ice usually focus either on the opening up of new frontiers for shipping and mineral exploitation, or on the plight of polar bears, which rely on sea ice for...

As a result of atmospheric patterns that both warmed the air and reduced cloud cover as well as increased residual heat in newly exposed ocean waters, such melting helped open the fabled Northwest Passage for the first time [see photo] this summer and presaged tough times for polar bears and other Arctic animals that rely on sea ice to survive, according to the U.S. Geological Survey.

With an overall length of 66 m, this versatile and stable vessel is suited for research on both coastal seas and open oceans (except for the polar regions).

a) Satellite image showing fast disintegration of sea ice over a polar continental shelf; b) Zoobenthos on an Antarctic continental shelf; c) Examples of sea mosses (specimens on the left are from an open - water location and hence have had more plankton to feed on); and d) Dead bryozoan and other benthic skeletons covering the seabed, most likely to be buried, sequestering their blue carbon in the seabed.

Collapsing ice shelves and melting sea ice leaves more open water in the Earth's polar regions (photo a in earlier figure).

Historically, there had not been enough open water for polar bears in this region to swim the long distances we observed in these recent summers of extreme sea ice retreat.»

A polar sea without ice opens a new stage in the glacial cycle.

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

These studies covered the entire spectrum of waterworld habitats — the polar and temperate seas, the open oceans, the tropics, the coral reefs, the kelp forests, the marine estuaries, and the fishing grounds.

The intercontinental highway through the polar sea has been open since July and will begin closing again in late October.

... observations suggested the bears drowned in rough seas and high winds and «suggest that drowning - related deaths of polar bears may increase in the future if the observed trend of regression of pack ice and / or longer open water periods continues.»

However, the fact that polar bears in the Chukchi Sea and Southern Davis Strait are thriving despite dramatic declines in summer sea ice (aka an extended open - water season), proves my point and disproves their premiSea and Southern Davis Strait are thriving despite dramatic declines in summer sea ice (aka an extended open - water season), proves my point and disproves their premisea ice (aka an extended open - water season), proves my point and disproves their premise.

«During aerial surveys in September 1987 — 2003, a total of 315 live polar bears were observed with 12 (3.8 %) animals in open water, defined for purposes of this analysis as marine waters > 2 km north of the Alaska Beaufort Sea coastline or associated barrier islands.

Schliebe, S., K. D. Rode, J. S. Gleason, J. Wilder, K. Proffitt, T. J. Evans, and S. Miller, 2008: Effects of sea ice extent and food availability on spatial and temporal distribution of polar bears during the fall open - water period in the Southern Beaufort Ssea ice extent and food availability on spatial and temporal distribution of polar bears during the fall open - water period in the Southern Beaufort SeaSea.

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134
