Antarctic Ocean Legacy: Towards Protection of the Weddell Sea Region [PDF]

open access: yes, 2014
Ice-bound, wild and remote, the Weddell Sea is a large, deep embayment nestled between the Antarctic Peninsula and Cape Norvegia. Lying south of the Atlantic Ocean, it is one of the most intact ecosystems in the world.At its widest, it is 2,000 km across,

The association of Antarctic krill Euphausia superba with the under-ice habitat.

open access: yesPLoS ONE, 2012
The association of Antarctic krill Euphausia superba with the under-ice habitat was investigated in the Lazarev Sea (Southern Ocean) during austral summer, autumn and winter.

Nanoplastics affect moulting and faecal pellet sinking in Antarctic krill (Euphausia superba) juveniles

open access: yesEnvironment International, 2020
Plastic debris has been identified as a potential threat to Antarctic marine ecosystems, however, the impact of nanoplastics (

Phytoplankton Bloom Changes During Three Regime Shifts Derived From Sea Ice Concentration in the Ross Sea

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Sea Ice Concentration (SIC) plays an important role in the Antarctic polynyas, especially where biological interactions through changes in chlorophyll‐a concentration (CHL) phenology are concerned. To specifically understand how much SIC change affects CHL in the Ross Sea polynya (RSP), the regime shift index (RSI) was applied to the SIC ...

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

open access: yesFrontiers 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.

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

open access: yesAntarctic 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.

Record phenological responses to climate change in three sympatric penguin species

open access: yesJournal of Animal Ecology, Volume 95, Issue 3, Page 455-469, March 2026.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

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

open access: yesPLoS 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

Ecological Feedbacks in the Earth System

open access: yesEarth's Future, Volume 14, Issue 2, February 2026.
Abstract Ecological feedbacks are fundamental features of the Earth system, affecting physical processes and chemical cycles. Our understanding of the interactions underlying these feedbacks at different spatial and temporal scales and the extent to which feedbacks affect Earth system functioning remains limited.
