Sentences with phrase «sea ice edge»

Interestingly, in the Seasonally Ice - free Zone (SIZ, the band located between the winter and summer sea ice edge), this production is highly stimulated by increased iron availability due to the seasonal sea ice retreat.

Improving Arctic sea ice edge forecasts by assimilating high horizontal resolution sea ice concentration data into the US Navy's ice forecast systems.

Air temperatures near the Antarctic sea ice edge were near average.

Ensemble decadal prediction simulations using the Community Earth System Model (CESM) can skillfully predict past decadal rates of Atlantic winter sea ice change because they do well at predicting THC - driven ocean heat content change in the vicinity of the winter sea ice edge in the Labrador, Greenland, Irminger, and Barents Seas.

• Study daily / seasonal sea ice edge movement and Arctic / Antarctic ice pack changes.

The Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE - NH) products provide measurements of daily sea ice extent and sea ice edge boundary for the Northern Hemisphere and 16 Arctic regions in a polar stereographic projection at both 1 km and 4 km grid cell sizes.

-- Sea ice edge positions for Newfoundland and the Canadian Maritime Region from observations, for 1870 to 1962.

But in 2010 I co-authored a paper with two sea ice experts and a historian / ethnologist in which we used nineteenth - century records from whaling ships hunting bowhead whales in the north Pacific and beyond, along the Arctic sea ice edge.

From these records, the researchers created a dataset of 191 sea ice edge positions, providing «an almost circumpolar picture of the Antarctic summer sea ice edge» for 1897 - 1917, the paper says.

The estimated DJFM Antarctic sea ice extent climatology for the period 1897 — 1917, with and without the inclusion of the Worby and Comiso offset (an offset between where satellites and human observers view the sea ice edge), is plotted alongside time series of DJFM mean sea ice extent calculated from HadISST2.2, NASA Team and NASA Bootstrap sea ice datasets.

It should also be clear that for any one locality, a shift in the storm tracks (associated with phenomena like the NAO or the sea ice edge) will often be more of an issue than the overall change in storm statistics.

-- The sea ice edge positions in the North Atlantic, between 1850 and 1978, derived from various sources, including newspapers, ship observations, aircraft observations, diaries and more.

Sea ice extent is defined as the surface area enclosed by the sea ice edge (where sea ice concentration falls below 15 %).

As a result the sea ice edge has been pushed towards Svalbard:

The answer is that since the effect of CO2 is at the surface, rather than distributed throughout the troposphere, then the surface of the Antarctic ice shelves melted supplying fresh water to the sea ice edge.

«That particular cyclone, which lasted several days and raised temperatures in the region close to the melting point, hindered sea ice growth while its associated strong winds pushed the sea ice edge back, leading to a record low spring sea ice pack in 2016,» Petty and Boisvert explained.

During January, the sea ice edge was located further north and further east than the 1981 - 2010 average sea ice edge, leaving both the Svalbard Archipelago and the island of Novaya Zemlya largely free of sea ice.

During July, the lower sea ice area was mainly due to a lower than average sea ice concentration across the whole sector, in particular in the northwestern parts of the Greenland Sea and in the Barents Sea, rather than a large shift in the sea ice edge.
