Report of the Working Group on the Effects of Extraction of Marine Sediments on the Marine Ecosystem (WGEXT)

The Working Group on the effects of extraction of marine sediments on the marine ecosystem (WGEXT) met at Stony Brook University, Manhattan, New York, USA, between 14 and 17 April, 2009. The meeting was chaired by Mr Gerry Sutton. Thirteen participants from eight ICES Member Countries were able to supply figures for marine aggregate extraction. Four other ICES countries participated by correspondence and the figures likely account for the majority of the total marine aggregate extracted in 2008.
