We present the first digital seafloor geomorphic features map (GSFM) of the global ocean. The GSFM includes 131,192 separate polygons in 29 geomorphic feature categories, used here to assess differences between passive and active continental margins as well as between 8 major ocean regions (the Arctic, Indian, North Atlantic, North Pacific, South Atlantic, South Pacific and the Southern Oceans and the Mediterranean and Black Seas). The GSFM provides quantitative assessments of differences between passive and active margins: continental shelf width of passive margins (88 km) is nearly three times that of active margins (31 km); the average width of active slopes (36 km) is less than the average width of passive margin slopes (46 km); active margin slopes contain an area of 3.4 million km2 where the gradient exceeds 5°, compared with 1.3 million km2 on passive margin slopes; the continental rise covers 27 million km2 adjacent to passive margins and less than 2.3 million km2 adjacent to active margins. Examples of specific applications of the GSFM are presented to show that: 1) larger rift valley segments are generally associated with slow-spreading rates and smaller rift valley segments are associated with fast spreading; 2) polar submarine canyons are twice the average size of non-polar canyons and abyssal polar regions exhibit lower seafloor roughness than non-polar regions, expressed as spatially extensive fan, rise and abyssal plain sediment deposits – all of which are attributed here to the effects of continental glaciations; and 3) recognition of seamounts as a separate category of feature from ridges results in a lower estimate of seamount number compared with estimates of previous workers.

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 2nd group, isopods occurrences sampled during the BIOICE project

ARCOD is the acronym for the data rescue project Archive of Ocean Data, former Arctic Ocean Sediment Data. The projects aim is to make data evailable in electronic, machine-readable form which are available in Russian archives and literature. The project is carried out since 2003 by Dr. Evgeny Gurvich.

HERMES data in PANGAEA only include meiobenthos abundances at the Arctic Håkon Mosby Mud Volcano (1037 records) and meiobenthos abundances in the Black Sea during Poseidon cruise. HERMES is a multidisciplinary research programme investigating Europe's deep marine ecosystems and their environment. Study sites extend from the Arctic to the Black Sea and include biodiversity hotspots such as cold seeps, cold-water coral mounds and reefs, canyons and anoxic environments, and communities found on open slopes.

This dataset was compiled to describe the intertidal meiobenthic community of Kongsfjorden and to better understand the relationship between the horizontal and vertical distribution of meiofauna with a special focus on nematodes and environmental features
