Macrofauna abundance matrix from litter samples from the North Sea 2020-2021 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFASa52e4cec-7409-4278-b18c-fec29cca7a1d Macrofauna abundance matrix for each taxa identified from litter samples, sorted by station. This is a combination of litter samples from the CEND 18/20 and CEND 06/21 CSEMP (Clean Safe Seas Environmental Monitoring Programme) surveys. The litter items are labelled with the station code and unique litter item and arranged in columns. The taxa names are listed in the rows. Corresponding abundance data for each taxa found on the litter item at that station is listed throughout the matrix. At the bottom of the taxa list is the categories: number of species, which includes the total; polymer type; whether the litter item was flexible or solid; the rugosity of the litter item; the size class; and the overall code describing these characteristics. 20241011 20241008
