Not exact matches

By mapping current conditions with the help of Inuit hunters as well as by compiling maps of the past based on oral histories and the memories of elders, the researchers hope to capture the Inuit's special understanding of sea ice.

«Southern Ocean: Reconstructing environmental conditions over the past 30,000 years: Sea - ice zone has a major influence on the ecosystem.»

Our study underlines that these conditions have led to a large loss of ice and significant rises in global sea level in the past.

The advantage of such partially - coupled models is that they can be driven by past atmospheric conditions and the simulations match well the observed sea ice variability, which is strongly forced by the atmosphere.

The main source of my Arctic comfort level — besides what I learned while camped with scientists on the North Pole sea ice — is the growing body of work on past variations * in sea ice conditions in the Arctic.

Arbetter et al. (National Ice Center); 4.4; Statistical The system determines the relationships between sea ice and atmospheric conditions over the past ten years to determine the likelihood of ice being present this yeIce Center); 4.4; Statistical The system determines the relationships between sea ice and atmospheric conditions over the past ten years to determine the likelihood of ice being present this yeice and atmospheric conditions over the past ten years to determine the likelihood of ice being present this yeice being present this year.

This is substantially lower than the earlier estimates, reflecting both lower than average sea ice extent used as initial conditions this summer and a persistent downward trend in sea ice extent over the past decade (and longer).

Similar sea ice trends and weather conditions were present during the spring seasons preceding past ice shelf retreats (e.g., 2001 to 2002).

If climate models are able to reproduce past warm climatic conditions (such as those of the LIG), including the extent of Arctic sea ice cover, we will have additional confidence in their representation of Arctic processes and their projections for the future20, 21,22,23.

By combination of this sea ice proxy IP25 with (biomarker) proxies for open - water phytoplankton productivity such as brassicasterol, dinosterol or a specific tri-unsaturated HBI (HBI - III) 37,38,39,40,41, a more precise (semi-quantitative) reconstruction of present and past Arctic Ocean sea ice conditions from marine sediments are now available (Supplementary Fig. 1; see Metho 6ds for some more details).

Proxy data such as those generated from ice core samples, measurements of tree rings intervals, bore samples taken from sediments from the ocean and sea floor, and measurement of gases from bubbles trapped in ice are some examples of preserved physical characteristics of the past used by scientists to reconstruct prevailing climatic conditions in the past.

Now we have poor hunting conditions in the Bering Strait touted as evidence that «walrus migration patterns have changed» with the implication that this is because ``... the past eight years have had the eight lowest amounts of summer sea ice on record» due to man - made global warming.

Research from the past 10 years has shown that climate change leads to longer seasons without sea ice, Stirling's team wrote, «resulting in polar bears coming ashore to fast [go without food] for several months in progressively poorer condition.»
