Loss of Sea Ice in the Arctic

Annual Review of Marine Science, 2009
The Arctic sea ice cover is in decline. The areal extent of the ice cover has been decreasing for the past few decades at an accelerating rate. Evidence also points to a decrease in sea ice thickness and a reduction in the amount of thicker perennial sea ice. A general global warming trend has made the ice cover more vulnerable to natural fluctuations

Arctic Ocean-Sea Ice Interactions

Proceedings of the Practice and Experience on Advanced Research Computing, 2018
This animation visualizes simulation results from research at The University of Texas at Austin, Institute for Computational and Engineering Sciences. Shown is the daily average temperature field of warm sub-surface water of subtropical origin carried with the Norwegian Atlantic boundary current into the Arctic Ocean, northwestward along the West ...

Perspectives on the Arctic's Shrinking Sea-Ice Cover

Science, 2007
Linear trends in arctic sea-ice extent over the period 1979 to 2006 are negative in every month. This ice loss is best viewed as a combination of strong natural variability in the coupled ice-ocean-atmosphere system and a growing radiative forcing associated with rising concentrations of atmospheric greenhouse gases, the latter supported by evidence of

History of sea ice in the Arctic

Quaternary Science Reviews, 2010
Abstract Arctic sea-ice extent and volume are declining rapidly. Several studies project that the Arctic Ocean may become seasonally ice-free by the year 2040 or even earlier. Putting this into perspective requires information on the history of Arctic sea-ice conditions through the geologic past. This information can be provided by proxy records from

An Ice Free Arctic Sea? The Science of Sea Ice and Its Interests

2013
The 2007 sea-ice minimum was quickly framed as a unique event and a very clear signal that the Arctic was a bellwether for global climate change. It became an event of the future it heralded rather than of the past or recent changes that had created it.

The thinning of Arctic sea ice

Physics Today, 2011
The surplus heat needed to explain the loss of Arctic sea ice during the past few decades is on the order of 1 W/m2. Observing, attributing, and predicting such a small amount of energy remain daunting problems.

Chlorophyll in Arctic Sea Ice

ARCTIC, 1965
Reviews investigations 1961-1963 into chlorophyll concentrations in sea ice in both arctic and antarctic regions. Results are compared with own researches off Devon Island, Canada, which are reported in detail. Chlorophyll a and c concentrations were obtained from underside of ice by a 7.5 cm diam ice corer and light penetration was measured by ...

Protists of Arctic Sea Ice

2017
Sea ice not only shapes the global climate but is also an important background for a complicated ecosystem that is closely related to the littoral benthic ecosystem. This similarity is the reason why this formation is usually referred to as an “inverted bottom.” In the deep central part of the Arctic Basin (which is 47% of its overall surface area), it

The Arctic and Antarctic Sea Ice

2018
This chapter covered Arctic and Antarctic climate. It discussed Arctic warming and focused on various related areas including Arctic Sea ice – last few years and recent decline. Recent behaviour of Antarctic Sea ice was also addressed.
