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.
