Predicting the potential distribution of major marine mammals in the Cosmonaut Sea

Frontiers in Marine Science
The Southern Ocean, a critical marine region on Earth, is undergoing significant environmental changes due to global climate change, including reductions in sea ice extent, ocean acidification, and alterations in the Antarctic Circumpolar Current (ACC ...

Diverse impacts of sea ice and ice shelf melting on phytoplankton communities in the Cosmonaut Sea, East Antarctica

Environmental Research Letters
Antarctic sea ice and glacier melt profoundly impacts marine ecosystems. Our study in the Cosmonaut Sea summer measures seawater oxygen isotopes, size-fractionated chlorophyll-a, and phytoplankton communities.

Age and feeding habits of Caml grenadier Macrourus caml in Cosmonauts Sea

Fishes, 2022
Abstract Macrourus caml is a main by-catch in the Southern Ocean fishery, and a main prey species of Antarctic toothfish, which plays an important role in Southern Ocean ecosystem. In this study, age estimation and stomach content analysis were conducted by using samples collected from the Cosmonauts Sea in 2021.

Biodiversity of Demersal Fish Communities in the Cosmonaut Sea Revealed by DNA Barcoding Analyses [PDF]

Genes (Basel)
The Cosmonaut Sea is one of the least accessed regions in the Southern Ocean, and our knowledge about the fish biodiversity in the region is sparse. In this study, we provided a description of demersal fish diversity in the Cosmonaut Sea by analysing cytochrome oxidase I (COI) barcodes of 98 fish samples that were hauled by trawling during the 37th and

Temperature structure and characteristics appearing on SSM/I images of the Cosmonaut Sea, Antarctica [PDF]

Annals of Glaciology, 1994
Water-temperature structure in the Cosmonaut Sea at 60 68° S, 35 65° E in 1987–92 shows that cold water with a temperature below -1.5°C was present in the coastal region. The Circumpolar Deep Water with a temperature higher than 1.0°C was found below about 150m depth from northeast to northwest of the cold water area.

Comparison of Minimum Taxonomic Unit Division Pipelines in Metabarcoding Analysis of Antarctic Phytoplankton Communities [PDF]

Progress in Fishery Sciences
The Southern Ocean plays a pivotal role in global carbon cycling and climate regulation. As a fundamental component of Antarctic ecosystems, phytoplankton provide the main nutritional support for Antarctic krill (Euphausia superba Dana), a vital fishery ...
