The distribution and diversity of amphipod crustaceans of Icelandic waters, in water depths between 18-3700 m, was examined and how it relates to environmental parameters and depth. Data on amphipod occurrence and abundance were collated from the historical literature (Ingolf Expedition, 1895-96), as well as recent expeditions (1998-2018) such as BioIce (Benthic invertebrates of Icelandic waters) and IceAge (Icelandic marine Animals: Genetics and Ecology, www.iceage-project.org) resulting in 355 amphipod species amongst 71,108 individuals from 532 localities. Samples were taken by a number of trawled sampling devices, including different types of dredges and sledges, as well as Remotely Operated Vehicle (ROV). A 1 ° hexagonal grid was constructed in to map the distribution of the amphipod species alongside twelve environmental factors retrieved from the Bio-Oracle 2.1 database. Due to strong autocorrelation of some of these factors, the analysis was limited to a set of eight variables: depth, pH, ...
