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

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 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 specimens investigated on morphological and molecular basis in this study were sampled in the course of different projects: The IceAGE program (Icelandic marine Animals: Genetics and Ecology, Brix et al. 2014a) is an ongoing research project (IceAGE 2 in 2013, IceAGE-RR in 2018, IceAGE 3 in 2020) which was established as a follow up of the very successful BIOFAR (Biology of the Faroe Islands, Nørrevang et al. 1994; Gerken and Watling 1999) and BIOICE (Benthic Invertebrates of Icelandic waters, Omarsdottir et al. 2013) projects. It is aimed to develop into a long-term study to get an overview of the biodiversity in this extremely diverse region around Iceland with a variety of different habitats and environmental challenges in its adjacent waters. Based on genetic and morphological diversity, it aims to create an inventory of the fauna as elementary knowledge for a comprehensive understanding of possible responses to changing climate conditions in marine environments (Brix et al. 2014a). The focus of the expedition PS106/1 (ARK-XXXI/1.1, 24th of May – 21st of June, 2017) off northern Svalbard onboard the RV Polarstern in course of PASCAL (Physical feedbacks of Arctic PBL, Sea ice, Cloud and Aerosol) was an interdisciplinary approach for studying the interaction of different Arctic feedback mechanisms based on atmospheric, oceanographic, physical and biological studies (Macke and Flores 2018). In this context the vessel was attached to an ice floe during a two-week passive drifting according to the ocean’s current as a preliminary trial-expedition to the first year-round MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition (Sep/2019 – Sep/2020).

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.

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).
