Polar Oceans in Peril and a Planet at Risk [PDF]
, 2009 The snow-covered lands and icy waters of these polar regions are, for many people, the purest examples of true wilderness left on this planet. While the Arctic has been home to indigenous peoples for millennia, Antarctica has only played host to visiting

Do small swimmers mix the ocean?
, 2010 In this communication we address some hydrodynamic aspects of recently revisited drift mechanism of biogenic mixing in the ocean (Katija and Dabiri, Nature vol. 460, pp. 624-626, 2009).

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.Abstract We use shipboard ADCP data (1999–2018) and a box‐integration approach to study the spatial and seasonal variability that regulates water mass exchanges between the Bellingshausen and Weddell Seas in the northwest Antarctic Peninsula. This system comprises three major currents: the Gerlache Strait Current (GSC), the Bransfield Current (BC), and

Physical Drivers of Phytoplankton Bloom Initiation in the Southern Ocean's Scotia Sea [PDF]
, 2019 : The Scotia Sea is the site of one of the largest spring phytoplankton blooms in the Southern Ocean. Past studies suggest that shelf‐iron inputs are responsible for the high productivity in this region, but the physical mechanisms that initiate and ...

A bioenergetics model for estimating prey consumption by an Adélie penguin population in East Antarctica [PDF]
, 2015 Quantifying prey consumption by top predators is a crucial component of ecosystem-based management in the Southern Ocean. In this study, we developed a bioenergetics model to estimate prey consumption by a top predator, the Adélie penguin Pygoscelis ...

Characterisation of the Pump-Suction Flow Field of Antarctic Krill and Key Influencing Factors
Applied SciencesTo address the problem of high damage rates and low efficiency during Antarctic krill pumping, this study used Discrete Phase Modelling (DPM) computational fluid dynamics (CFD) to analyse how krill–water mixing ratios and centrifugal pump speeds affect ...

Blocking primers to enhance PCR amplification of rare sequences in mixed samples – a case study on prey DNA in Antarctic krill stomachs [PDF]
, 2008 Background Identification of DNA sequence diversity is a powerful means for assessing the species present in environmental samples. The most common molecular strategies for estimating taxonomic composition depend upon PCR with universal ...

Deterioration of Antarctic Krill Muscle during Freeze Storage
Agricultural and Biological Chemistry, 1983 The effects of freezing on the heat-induced gelation, Ca2+-ATPase activity and myofibril structure of Antarctic krill muscle were investigated. Muscle from freshly caught krill was immediately stored at-20°C in the presence (to prevent freezing) (glycerol krill) and absence (frozen krill) of glycerol.
