This dataset is a stationlist of the 3 cruises which were undertaken in the framework of the ICEAGE project (Icelandic marine Animals: Genetics and Ecology). This station list contains all stations of the M85/3 (2011-08-27/09-28) , POS456 (2013-07-20/08-04) and MER75 (2018-06-29/08-08) cruises. The samples taken at these stations we analysed for the presence and abundance of isopods and amphipods for which the data can be found in other datasets linked to this dataset record.

Isopoda from this data set were collected during the DIVA (Latitudinal Gradients of Deep-Sea BioDIVersity in the Atlantic) 1-2 expeditions (Me 48/1 -DIVA 1; Me 63/2 - DIVA 2) on board RV Meteor, taking place in July 2000 (DIVA 1), and between February and March 2005 (DIVA 2). Samples were taken by means of an epibenthic sledge (EBS). A total of 15 EBS samples were taken in three abyssal basins of the equatorial and South-eastern Atlantic at depths between 5,047 and 5,657 m, Guinea basin in the equatorial Atlantic, as well as the Angola and Cape basins in the SE Atlantic. Macroecological patterns of diversity and abundance in the deep sea have been derived to a large extent from macrofaunal data from the North Atlantic, while data from the Southern Hemisphere abyss are sparse. This leads to a somewhat distorted view of biodiversity patterns along latitudinal gradients.

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>

Benthic isopods from this data set were collected during the IceAGE 3 expedition (SO276) on board RV Sonne in July 2020 with an epibenthic sledge (EBS). A total of seven EBS samples were taken in two areas of the Aegir ridge (Norwegian basin) at depths between 681 m to 3,702 m. The benthic samples taken are the first from the deep seabed within the Aegir ridge and therefore represent an important data set for assessing the diversity of the deep Nordic seas and their relationship to water mass distribution and depth. Isopoda collected by the EBS contained 1,978 specimens divided into eleven families, 25 genera and at least 42 species. Munnopsidae were by far the most dominant family contributing 59.1% to total isopod specimens, followed by the Munnidae (18.3) and Katianiridae (17.8). The remaining families were present with less than 5% of total Isopoda.

This Amphipoda 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). The IceAGE data are outcome of two Amphipoda identification workshops held in Wilhelmshaven, Germany (2016) and Spala, Polen (2017).

Benthic Haploniscidae (Iopoda) in this data set were collected during BIOICE (Benthic invertebrates of Icelandic waters), IceAGE (Icelandic marine Animals: Genetics and Ecology), IceAge 2 (Icelandic marine Animals: Genetics and Ecology 2), IceAGE RR (Icelandic marine Animals: Genetics and Ecology Reykjanes Ridge) and IceAge 3 (Icelandic marine Animals: Genetics and Ecology cruises 3) projects during 1992- 2020

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).

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
