Using seabird and whale distribution models to estimate spatial consumption of krill to inform fishery management

Ecosphere, 2022
Ecosystem dynamics at the northwest Antarctic Peninsula are driven by interactions between physical and biological processes. For example, baleen whale populations are recovering from commercial harvesting against the backdrop of rapid climate change ...

Sinking krill carcasses as hotspots of microbial carbon and nitrogen cycling in the Arctic

Frontiers in Marine Science, 2022
Krill represent a major link between primary producers and higher trophic levels in polar marine food webs. Potential links to lower trophic levels, such as heterotrophic microorganisms, are less well documented.

Antarctic Krill Biomass and Flux Measured Using Wideband Echosounders and Acoustic Doppler Current Profilers on Submerged Moorings

Frontiers in Marine Science, 2022
During austral summer 2018/2019, we deployed an array of six submerged moorings equipped with Nortek Signature100 integrated wideband echosounder and acoustic Doppler current profilers (ADCPs) on the continental shelf of the northern Antarctic Peninsula.

Implications for the mesopelagic microbial gardening hypothesis as determined by experimental fragmentation of Antarctic krill fecal pellets

Ecology and Evolution, 2021
Detritivores need to upgrade their food to increase its nutritional value. One method is to fragment detritus promoting the colonization of nutrient‐rich microbes, which consumers then ingest along with the detritus; so‐called microbial gardening ...

Setting a precautionary catch limit for Antarctic krill [PDF]

, 2002
A revised precautionary catch limit for Antarctic krill (Euphausia superba) in the Scotia Sea of 4 million tons was recently adopted by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Krill and salp faecal pellets contribute equally to the carbon flux at the Antarctic Peninsula

Nature Communications, 2021
Krill and salps are important for carbon flux in the Southern Ocean, but the extent of their contribution and the consequences of shifts in dominance from krill to salps remain unclear. We present a direct comparison of the contribution of krill and salp

Catch Pattern for Antarctic krill (Euphausia superba) of Different Commercial Trawls in Similar Times and Overlapping Fishing Grounds

Frontiers in Marine Science, 2021
Antarctic krill (Euphausia superba) is harvested using different design midwater trawls. Knowing the selective properties between trawls is crucial information for the management of the krill resources.

Загрязненность прибрежной экосистемы тяжелыми металлами как показатель климатических изменений в Антарктике

Український антарктичний журнал, 2020
Во время предыдущих исследований в районе Украинской антарктической станции (УАС) Академик Вернадский нами было обнаружено повышенное содержание тяжелых металлов в донных осадках и в грунтах о-вов Аргентинского архипелага и выявлена аккумуляция тяжелых ...

Acoustic Detection of Krill Scattering Layer in the Terra Nova Bay Polynya, Antarctica

Frontiers in Marine Science, 2020
Krill play a crucial role in the transfer of energy in the marine food web, connecting primary producers and the upper trophic levels in the Terra Nova Bay polynya (TNBP), which is part of the Ross Sea marine protected area.
