Integral values of biomass and stock of zooplankton in the epipelagic layer of the area 71 in the North Pacific, including the Bering and Okhotsk Seas, and patterns of distribution for mass species

open access: yesИзвестия ТИНРО, 2015
The Okhotsk and Bering Seas and the subarctic zone of the North Pacific are surveyed well by the expeditions conducted by Pacific Fish. Res. Center (TINRO) in the last three decades (115 surveys in 1984-2013), with sampling of zooplankton for monitoring ...

Zooplankton biomass in the ice-covered Weddell Sea, Antarctica [PDF]

open access: yes, 1991
Zooplankton was sampled by a Rectangular Midwater Trawl (RMT 1 + 8) in Weddell Sea surface waters (0 to 300 m) between 66 and 78°S during austral summer (February – March 1983). Sixty-nine taxa including different developmental stages were considered and

Ocean-bottom krill sex [PDF]

open access: yes, 2011
For the first time the entire sequence of the mating behaviour of Antarctic krill (Euphausia superba) in the wild is captured on underwater video. This footage also provides evidence that mating can take place near the seafloor at depths of 400700 m ...

Summer Diet of Humpback Whales in the Northern Strait of Georgia, British Columbia (Canada), Revealed by Stable Isotope Analysis

open access: yesMarine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT North Pacific humpback whales (Megaptera novaeangliae) have recovered rapidly following their depletion by commercial whaling. Diet studies are necessary to assess food web implications of their recovery. This study investigates the diet composition of humpback whales foraging in the northern Strait of Georgia, British Columbia, Canada, an ...

Feeding Ecology of Three Euphausiid Species in the North Pacific Ocean Inferred From 18S V9 Metabarcoding and Stable Isotope Analysis

open access: yesFrontiers in Marine Science, 2021
Euphausiids are abundant micronekton and important links between higher and lower trophic levels in marine ecosystems; however, their detailed diets cannot be fully understood by conventional microscopy, especially in subtropical areas.

Evaluation of Antarctic krill (Euphausia superba) meal supplementation in diets for olive flounder (Paralichthys olivaceus)

open access: yes, 2020
The supplemental effect of Antarctic krill meal (KM) into a low fish meal (FM) diet was evaluated for olive flounder (Paralichthys olivaceus). A 56% FM‐based diet was regarded as a high FM inclusion diet (HFM), and a low‐FM diet (LFM) was prepared by ...

The Biodiversity of Peter I Island—The Most Remote Island in the World

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
Peter I Island is one of the most isolated and least visited islands on earth; lying within the Antarctic Polar Front but over 420 km from continental Antarctica. Here we assess the biodiversity of the island from both previous records and our own BioBlitz in January 2022.
