Arctic sea ice loss impacts beluga whale migration
Arctic sea ice loss beluga whale migration
2017/2/15
The annual migration of some beluga whales in Alaska is altered by sea ice changes in the Arctic, while other belugas do not appear to be affected.A new study led by the University of Washin...
Local climatic changes impact algae living inside the sea ice, which may drastically affect near shore Arctic marine food webs
Scientists traveled to a town near the top of the world to study a creat...
They know the drill: UW leads the league in boring through ice sheets（图）
ice sheets The university of Wisconsin Antarctica
2014/12/3
Wisconsin is famous for its ice fishers — the stalwarts who drill holes through lake ice in the hope of catching a winter dinner. Less well known are the state’s big-league ice drillers — specialists ...
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,...
Using a camera-equipped robot to explore beneath the Ross Ice Shelf off Antarctica, scientists and engineers with the Antarctic Geological Drilling (ANDRILL) Program made an astonishing discovery.
There is growing scientific concern that corals could retreat from equatorial seas and oceans as the Earth continues to warm, a team of international marine researchers warned today.
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...
Nutritional importance of benthic bacteria for deep-sea nematodes from the Arctic ice margin: Results of an isotope tracer experiment
Nutritional importance benthic bacteria deep-sea nematodes the Arctic ice margin Results an isotope
2014/4/16
A stable isotope (13C)-labeling experiment was performed to quantify the importance of bacterial carbon as a food source for an Arctic deep-sea nematode community. Bacterial functional groups were iso...
Contribution of mycosporine-like amino acids and colored dissolved and particulate matter to sea ice optical properties and ultraviolet attenuation
amino acids colored dissolved
2014/4/16
In the Baltic Sea ice, the spectral absorption coefficients for particulate matter (PM) were about two times
higher at ultraviolet wavelengths than at photosynthetically available radiation (PAR) wav...
Connecting recruitment of Antarctic krill and sea ice
Connecting recruitment Antarctic krill sea ice
2014/4/18
We develop an age-structured model for two krill populations near the Antarctic Peninsula and estimate the relative recruitment events that reproduce observed trends in krill abundance and age structu...
Supersaturated N2O in a perennially ice-covered Antarctic lake: Molecular and stable isotopic evidence for a biogeochemical relict
Supersaturated N2O perennially ice-covered Antarctic lake Molecular and stable isotopic evidence biogeochemical relict
2014/4/21
The east lobe of Lake Bonney, a permanently ice-covered lake in the McMurdo Dry Valleys, Antarctica, has a mid-depth maximum N2O concentration of 43.3 μmol N L-1 (>700,000% saturation with respect to ...
Seasonal changes in planktonic bacterivory rates under the ice-covered coastal Arctic Ocean
Seasonal changes planktonic bacterivory rates the ice-covered coastal Arctic Ocean
2014/4/21
Bacterivory was determined in surface waters of Franklin Bay, western Arctic, over a seasonal ice-covered period (winter-spring, 2003-2004). The objectives were to obtain information on the functionin...
Ice-ocean turbulent exchange in the Arctic summer measured by an autonomous underwater vehicle
Ice-ocean turbulent exchange Arctic summer measured autonomous underwater vehicle
2014/5/16
The first-ever observed horizontal profiles of summertime ice-ocean boundary layer fluxes were obtained using vertical water velocity, temperature, and salinity collected by an Autonomous Underwater V...
Biogas (CO2, O2, dimethylsulfide) dynamics in spring Antarctic fast ice
Biogas dynamics in spring Antarctic fast ice
2014/4/22
We studied the temporal variations of CO2, O2, and dimethylsulfide (DMS) concentrations within three environments (sea-ice brine, platelet ice-like layer, and underlying water) in the coastal area of ...
Barnacle larvae in ice: Survival, reproduction, and time to postsettlement metamorphosis
Barnacle larvae in ice Survival reproduction postsettlement metamorphosis
2014/5/13
Late stage larvae (cyprids) of the barnacle Semibalanus balanoides frequently encounter freezing conditions along the northwest Atlantic coast. S. balanoides cyprids survived for more than 4 weeks emb...
