PARAMETERS COMPARSION OF LEADS DETECTION IN ARCTIC SEA ICE USING CRYOSAT-2 WAVEFORM DATA
Arctic, Sea ice, Lead, Satellite altimetry
2018/5/14
Leads are only a small part of the polar sea ice structure, but they play a dominant role on the turbulence exchange between the ocean and the atmosphere, they are also important factors about sea ice...
Advances in Sea-Ice Research Based on Remotely Sensed Passive Microwave Data
Advances Sea-Ice Research Remotely Sensed Passive Microwave Data
2015/8/19
Sea-ice cover is the most significant feature of the polar ocean environment. Annual cycles of sea-ice cover and their interannual variations contribute significantly to changes in surface reflectivit...
The availability of real-time information on sea ice conditions in ice covered seas has always been important, not only to strategic military operations, but to the economies of those countries that b...
Hovercraft as a Mobile Science Platform Over Sea Ice in the Arctic Ocean
Arctic Ocean Science Platform Over Sea Ice
2015/7/17
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...
Warm Arctic, Cold Continents: A Common Pattern Related to Arctic Sea Ice Melt, Snow Advance, and Extreme Winter Weather
Arctic sea ice statistical model the Eurasian snow winter temperatures
2015/7/16
Arctic sea ice was observed to be at a new record minimum in September 2012. Following this summer minimum, northern Eurasia and much of North America experienced severe winter weather during the wint...
Sea Ice Monitoring by Synthetic Aperture Radar
Sea Ice Monitoring Synthetic Aperture Radar
2015/7/16
Satellite-borne synthetic aperture radar (SAR) data are highly valuable not only for observing the open ocean but also for monitoring seasonally or permanently ice-covered ocean regions in the Arctic,...
Melting Ice:What is Happening to Arctic Sea Ice,and What Does It Mean for Us?
Melting Ice Arctic Sea Ice What Does It Mean for Us
2015/7/16
Sea ice has emerged as the canary in the coal mine of climate change. Its summer extent in the Arctic has decreased by about 50% over the past decade, and the Arctic Ocean has undergone a regime shift...
how is sediment transported to the seafloor
along coastlines where the sea ice rarely
melts? Are there distinctive characteristics
of the resulting deposits that label them as
accumulating in ...
As the world’s ice diminishes in the face of climate change—from the
dramatic decline in Arctic sea ice, to thinning at the margins of both the Greenland
and Antarctic ice sheets, to retreating mo...
Identifying variable sea ice carbon contributions to the Arctic ecosystem: A case study using highly branched isoprenoid lipid biomarkers in Cumberland Sound ringed seals
Sea ice carbon The arctic ecosystem
2014/10/16
We analyzed liver samples from 322 ringed seals (Pusa hispida) collected from Cumberland Sound (southeast
Baffin Island) to test our ability to differentiate between carbon sources in near apex preda...
Biological- and physical-induced oxygen dynamics in melting sea ice of the Fram Strait
Biological- and physical-induced oxygen dynamics melting sea ice Fram Strait
2014/7/10
We investigated the production, consumption, and exchange of O2 in melting sea ice to assess the biological- and physical-induced O2 turnover. The underside of the ice was covered with 5–20 cm3 large,...
Feeding and overwintering of Antarctic krill across its major habitats: The role of sea ice cover, water depth, and phytoplankton abundance
Antarctic krill Feeding water depth
2014/4/2
Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean
(Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...
On the existence of stable seasonally varying Arctic sea ice
existence stable seasonally varying Arctic sea ice
2012/2/28
Within the framework lower order thermodynamic theories for the climatic evolution of Arctic sea ice we isolate the conditions required for the existence of stable seasonally-varying ice states. This ...
Rapid photoprotection in sea-ice diatoms from the East Antarctic pack ice
Rapid photoprotection sea-ice diatoms the East Antarctic pack ice
2014/4/17
Photoinhibition and D1 protein re-synthesis were investigated in bottom-dwelling sea-ice microalgal communities from the East Antarctic pack ice during early spring. Bottom-dwelling sea-ice microalgal...
Comparison of zooplankton vertical migration in an ice-free and a seasonally ice-covered Arctic fjord: An insight into the influence of sea ice cover on zooplankton behavior
zooplankton vertical migration sea ice
2014/4/16
We present observations of zooplankton diel vertical migration (DVM) over a period of 2 yr in an ice-free and
a seasonally ice-covered Arctic fjord. The contrasting environments permitted assessment ...
