[ Get Data ]

Abstract: Macrobenthic infauna collections were made to investigate potential changes in community structure (abundance, biomass, diversity) in the Chirikov Basin, northern Bering Sea between 1986 and 2002; one of the biomass hot spot region in the Arctic. Two cruises to the Chirikov Basin were conducted in the years 1986 and 2002 with the R/V/ Alpha Helix. Samples were taken at the same 20 stations during ... View entire text

Purpose: To asses community structure (abundance, biomass, diversity) of the infauna of the Chirikov Basin, northern Bering Sea for the years 1986 and 2002.

GRAB SAMPLERS Ancillary Description
Quality ATTRIBUTE ACCURACY REPORT: Accuracy of the van Veen grab was not tested. The complete grab sample was washed over 1 mm screen and all specimens were preserved and later sorted. When hitting the sea floor, van Veen grabs blow away an unknown (specimen-density specific) portion of the sediment surface. Despinte this, van Veen grabs are the standard tool for sampling macroinfauna (details in “Methods ... View entire text
