Epistemic opacity in Antarctic science: Unknowing the last frontier

People and Nature, Volume 8, Issue 6, Page 1641-1647, June 2026.
Abstract Antarctica is facing intensifying pressures from climate change, industrial fishing, tourism and renewed geopolitical competition, even as scientific activity on the continent reaches unprecedented levels. We argue that this proliferation of research often fails to deliver the integrated, policy‐relevant knowledge needed for precautionary ...

Conservation planning in the Weddell Sea (Antarctica): A comparative analysis of decision‐support tools

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
We compare simulated annealing (SA, Marxan) and integer linear programming (ILP, prioritizr) to evaluate their performance in developing spatial conservation priorities for the proposed Weddell Sea Marine Protected Area Phase 1. While both approaches identify largely overlapping priority areas, ILP consistently produces more compact and cost‐efficient ...

Penguin guano suppresses the grazing rate and modifies swimming behavior in Antarctic Krill (Euphausia superba)

Frontiers in Marine Science
Antarctic krill (Euphausia superba) are a key component of the Antarctic ecosystem linking primary and some secondary production to higher trophic levels including fish, penguins, seals, and whales.

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Distribution of the Antarctic Sea-birds in the Outer Margin of the Summer Pack Ice Area

Antarctic Record, 1979
The distribution of the Antarctic sea-birds was investigated in 1976-1977 and 1977-1978 summer seasons. The observations were performed along the outer margin of the pack ice area between longitude 50° E and 165° E.

Identifying Risk: Concurrent Overlap of the Antarctic Krill Fishery with Krill-Dependent Predators in the Scotia Sea.

PLoS ONE, 2017
Mitigating direct and indirect interactions between marine predators and fisheries is a motivating factor for ecosystem-based fisheries management (EBFM), especially where predators and fisheries compete for a shared resource. One difficulty in advancing

Size Selection of Antarctic Krill (Euphausia superba) in Trawls

PLoS ONE, 2014
Trawlers involved in the Antarctic krill (Euphausia superba) fishery use different trawl designs, and very little is known about the size selectivity of the various gears. Size selectivity quantifies a given trawl's ability to catch different sizes of a harvested entity, and this information is crucial for the management of a sustainable fishery.
