abstract: Regional monitoring data from the seas surrounding Sweden.
description: The data are often collected with the help of divers who follow a transect - line along the seabed . The divers observe the occurrence of different species on the ground . What is observed is recorded either on site or analyzed retrospectively based on photographs, videos or samples collected by divers . Often noted the observationdepth, position along the transect line and the sampled surface along the transect line . The methods vary greatly. For each species are presented : measurements : how many there are in a given area (Abundance , Abundance Class), how many are counted (# Counted), the proportion of ground covered (% Cover, Cover Class) or the maximum depth it grew on (Species distribution and maximum depth) . Often also reported the bottom sediment type and the proportion of the bottom that is covered by sediment (sediment deposition cover) .
