Nekton community of the Scotia Sea as sampled by the RMT 25 during austral summer [PDF]
The nekton community was sampled by a Rectangular Midwater Trawl (RMT 25) over the upper 1000 m of the Scotia Sea dunng January 1991. A total of 81 nekton and micronekton species were collected from 2 sites, one in the oceanlc western Scotia Sea (Stn 1)

We examined the dB difference in target strength at multiple frequencies (ΔTS) for the identification of Antarctic krill (Euphausia superba) and ice krill (Euphausia crystallorophias) using a stochastic distorted-wave Born approximation model.

Predatory impact of the myctophid fish community on zooplankton in the Scotia Sea (Southern Ocean) [PDF]
Myctophids are the most abundant mesopelagic fishes in the Southern Ocean, although their trophic role within the predominantly krill-based food web in regions south of the Antarctic Polar Front (APF) is poorly resolved. This study therefore examined the

Antarctic krill ( Euphausia superba Dana, 1850) exemplifies the key role of marine crustaceans in fisheries, foodwebs, and biogeochemical cycles. Ecological understanding and policy decisions require information on population trends.

Cohort tracking using size‐frequency population survey data to estimate individual growth
Abstract The relationship between a species' growth rate and its size—its growth function—represents essential biological information for supporting sustainable fisheries and wildlife management. Yet, growth functions are known for only a fraction of species. Progress is especially limited in marine invertebrates, including shellfish, due to challenges

Characterization of polymorphic microsatellite loci in the Antarctic krill Euphausia superba [PDF]
Background: The Antarctic krill, Euphausia superba is a pelagic crustacean, abundant in high-density swarms (10 000 – 30 000 ind/m2) with a circumpolar distribution and a key role in the food web of the Southern Ocean.

Do small swimmers mix the ocean?
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).
