This data set consists of the benthic sampling carried out beyond the
continental shelf in the Gulf of Mexico by Willis Pequegnat of Texas A&M,
primarily in the 1960's and 70's. The data were hand entered from a copy of:
Pequegnat, W.E. 1983. The ecological communities of the continental slope and
adjacent regimes of the northern Gulf of Mexico. Prepared for the Minerals
Management Service under ... contract AA851-CT1-12.
A variety of sampling gear was used, but most samples were collected with a
wire-mesh dredge (Skimmer) and an otter trawl. Most of the animals are in the
megafauna size class.
The sampling was unique in that it was carried out around the Gulf of Mexico
prior to restrictions on sampling in the EEZ. Taxonomic quality control
should be good, especially for crustacea and echinoderms. Pequegnat actively
submitted vouchers to the U.S. National Museum of Natural History and
cooperated with a number of experts. It is not, however, possible to be
certain which specimens in the data set were actually examined by experts.
This data set was converted in a format suitable for OBIS by R.S. Carney of
Louisiana State University with support from the Minerals Management Service.
