Spatial Variability in Phytoplankton Response to Projected Increases in Iron and Temperature in the Ross Sea

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The Ross Sea supports massive phytoplankton blooms and exhibits the highest marine primary productivity rates due to seasonal relief of iron and light limitations. Although Earth System Models project regional increases in temperature and iron supply, there is uncertainty regarding the response of different phytoplankton communities. To assess

Spatial data of Antarctic krill (Euphausia superba) fishery in the Western Antarctic Peninsula

open access: yes, 2020
Spatial data of Antarctic krill (Euphausia superba) fishery in the Western Antarctic Peninsula, consisting of two GIS files: a spatial grid (geotif) with number of years of fishing effort occurring in a given cell, and a spatial polygon file, both in ...

Resolving environmental drivers of microbial community structure in Antarctic soils [PDF]

open access: yes, 2009
Antarctic soils are extremely cold, dry, and oligotrophic, yet harbour surprisingly high bacterial diversity. The severity of environmental conditions has constrained the development of multi-trophic communities, and species richness and distribution is ...

Factors impacting the timing of reproductive development in female Antarctic krill at the northwestern Antarctic Peninsula

open access: yesFrontiers in Marine Science
The northwestern Antarctic Peninsula is an important spawning, recruitment, and overwintering ground for Antarctic krill. The region is warming rapidly, and the current impacts of climate and environmental variability on the reproductive cycle of krill ...

Molecular Mechanism of Absorption, Transport and Metabolic Transformation of Astaxanthin in Aquatic Animals

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
This manuscript systematically elucidates the molecular mechanisms underlying absorption, transport, and metabolism of Astaxanthin in aquatic animals, through the analysis of biological functions, transport proteins, and enzyme metabolism system. Furthermore, it outlines future molecular research strategies for Astaxanthin, providing a theoretical ...

Enabling Under Ice Glider Operations: A Backseat Driver Approach

open access: yesJournal of Field Robotics, Volume 43, Issue 5, Page 3292-3311, August 2026.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

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.

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.

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

open access: yesRemote Sensing in Ecology and Conservation, Volume 12, Issue 4, Page 645-660, August 2026.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...
