Quantitative Benthic Samples from the Deep Gulf of Mexico with Some Comments on the Measurement of Deep-Sea Biomass
Anchor dredge samples and a photographic survey indicate that the benthic fauna of the deep Gulf of Mexico is depauperate compared to other basins. Infaunal biomass (expressed in terms of wet weight, dry weight, animal numbers, and organic carbon) decreased logarithmically with depth (i.e., logarithm10 mg C/m2 = 2 − 0.000522 [depth]) suggesting considerable energy loss in the passage of food along a complex food “ladder” in the water column.
