Benthic macrofaunal abundance data from the Western North Sea collected from 2000 to 2002

Data contains the abundance of macrofauna in benthic samples obtained from 0.1m2 Hamon or Day grab samples conducted by Cefas in the Western North Sea between 2000-2002. Sampling occurred mainly in spring and early summer of 2000 in the North Sea. Sampling was conducted with a 0.1m2 Day or Hamon grab depending on the sediment type. Macrofauna were identified to species level and enumerated, with macrobenthos density derived.
