An 18S V4 rRNA metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, through the year and down to 1000 m depth [PDF]

open access: yesEarth System Science Data, 2021
Arctic marine protist communities have been understudied due to challenging sampling conditions, in particular during winter and in deep waters. The aim of this study was to improve our knowledge on Arctic protist diversity through the year, in both the ...

Epipelagic representations and rigid local systems [PDF]

open access: yesSelecta Mathematica, 2016
We construct automorphic representations for quasi-split groups $G$ over the function field $F=k(t)$ one of whose local components is an epipelagic representation in the sense of Reeder and Yu. We also construct the attached Galois representations under the Langlands correspondence.

Food limitation and growth in temperate epipelagic appendicularians (Tunicata) [PDF]

open access: yesMarine Ecology Progress Series, 2003
Through an extensive review of reports on appendicularian ecology, we have developed a set of equations on the feeding, metabolic and growth rates of temperate epipelagic appendicularian species. We have used these equations to study the conditions in which these species are likely to ex- perience food-limited growth.

Using a recreational grade echosounder to quantify the potential prey field of coastal predators.

open access: yesPLoS ONE, 2019
Quantifying the distribution of prey greatly improves models of habitat use by marine predators and can assist in determining threats to both predators and prey.

Long-term dynamics of forage base and food supply for nekton in the upper epipelagic layer of the western Bering Sea. Part 1. Composition and abundance of zooplankton and small-sized nekton

open access: yesИзвестия ТИНРО, 2022
An updated concept for the state, dynamics, and production of plankton communities in the upper epipelagic layer of the western Bering Sea is presented based on the timeseries for 1986–2020.

Diving behaviour of whale sharks in relation to a predictable food pulse [PDF]

open access: yes, 2005
We present diving data for four whale sharks in relation to a predictable food pulse (reef fish spawn) and an analysis of the longest continuous fine-resolution diving record for a planktivorous shark.

Genomic Comparison and Spatial Distribution of Different Synechococcus Phylotypes in the Black Sea

open access: yesFrontiers in Microbiology, 2020
Picocyanobacteria of the genus Synechococcus are major contributors to global primary production and nutrient cycles due to their oxygenic photoautotrophy, their abundance, and the extensive distribution made possible by their wide-ranging biochemical ...

Significance of gene variants for the functional biogeography of the near-surface Atlantic Ocean microbiome

open access: yesNature Communications, 2022
The taxonomic and functional diversity of marine microbial communities are shaped by both environmental and biotic factors. Here, the authors investigate the functional biogeography of epipelagic prokaryotic communities along a 13,000-km transect in the ...

Multibeam volume acoustic backscatter imagery and reverberation measurements in the Northeastern Gulf of Mexico [PDF]

open access: yes, 2002
Multibeam volume acoustic backscatterimagery and reverberation measurements are derived from data collected in 200-m-deep waters in the northeastern Gulf of Mexico, with the Toroidal Volume Search Sonar (TVSS), a 68-kHz cylindrical sonar operated by the ...

Global patterns of epipelagic gelatinous zooplankton biomass

open access: yesMarine Biology, 2011
There is concern that overfishing may lead to a proliferation of jellyfish through a process known as fishing down the food web. However, there has been no global synthesis of patterns of gelatinous zooplankton biomass (GZB), an important first step in determining any future trends.
