The primary objective for developing a CeDAMar database is to generate a map of biological abyssal sampling stations in the World Ocean. These data represent the European coverage.

This experimental research in glacial Kongsfjorden (Spitzbergen) investigates the long term colonisation capacities of Arctic soft bottom meiofauna.

These data give - for the first time - an overview of the meiofauna that inhabits the slope and the abyssal plains in Antarctic waters to a depth of 5 200 m.

This datasets contributes to a better understanding of diversity in small peracarid crustacean and their possible distribution patterns in remote deep-sea regions. It contains specimen ocurrence records of the taxon Cumacea sampled with diverse benthic gears (epibenthic sledges, box corer) on the Yermak Plateau north of Svalbard during the PASCAL project with RV Polarstern in 2017 and during the IceAGE expedition IceAGE1 in 2011 in deep sea regions of the Nordic GIN-Seas (Greenland, Iceland and Norwegian Sea).

A quantitative small-scale snap-shot investigation on an intertidal sandflat in Jade Bay (North Sea) was conducted.

The main question in this research was how Harpacticoid copepod communities differ in species composition and diversity on a north to south gradient in the Western Baltic area and what factors might explain these differences

The North Atlantic and Arctic Isopoda dataset contains three parts: 1. Distribution records collected from literature; 2. Distribution records of specimens collected by the BIOICE project (Benthic Invertebrates of Icelandic waters 1992-2004); 3. Distribution records of specimens collected by the IceAGE project (Icelandic marine animals: Genetics and Ecology, since 2011). This dataset contains distribution data regarding the 3nd group, isopods occurrences sampled during the IceAGE project

This dataset contains Amphipod distribution records and is based on literature from the years 1931 to 2018. The data were collected during a variety of cruises and sampling events while the majority was obtained during the Danish Ingolf expedition. Sampling events took place in the North Atlantic and Arctic waters which included the Artic Ocean, Barents Sea, Kara Sea, Labrador Sea, Buffin Bay and Greenland Sea. Amphipods were predominantly collected using dredges, epibenthic sledges and remotely operated vehicles but scuba divers and vehicle-free baited traps were also used. This way, over 1566 Amphipod samples were collected in total which include 45 families, 117 genera and 164 species.

<p>The species <i>Mulinia lateralis</i> (Say, 1822) is native in the western Atlantic Ocean and was first documented in European coastal waters in 2017. To report its current distribution status in the central Wadden Sea, individuals were collected systematically from intertidal flats along 10 transects ranging from the outer Ems estuary to the outer Elbe estuary (German North Sea coast) between February and May 2022. In total, 897 specimens of M. lateralis were sampled from 392 stations (mean abundance 2.29 ± 4.97 ind./m²). The shell length ranged between 3.98 to 23.5 mm thus representing.&nbsp;</p>
