Seamap Data - Live Bottom 1982-1999
Entry ID: SEAMAP_LIVE_BOTTOM



Summary
Abstract: This data set consists of epibenthic organisms found in nets during
trawls on the Texas-Louisiana-Mississippi continental shelf conducted as part
of the Southeast Area Monitoring and Assessment Program (SEAMAP), a joint
effort of the NOAA National Marine Fisheries Service and the Gulf states. The
trawl sites data base represents approximately 12,800 trawl start locations
(latitude and longitude) in the Gulf of Mexico during 1982-1999. The live
bottom data base represents the subset of start locations where live bottom
organisms were recorded. Live bottom organisms were defined as those that are
attached to the bottom (sessile) and project into the water column, thus
providing structure to an potentially otherwise unstructured sand, mud, or rock
bottom. Live bottom organisms included sponges, corals, sea fans, sea pansies,
gorgonians, sea pens, bryozoans, endoprocts, and crinoids. Data are maintained
by the National Marine Fisheries Service and were provided by Mark McDuff, NOAA
Fisheries, Pascagoula, MS.


Purpose: This was one of fifty-seven GIS data layers created by scientists at
the Fisheries Ecology Branch of the NOAA National Marine Fisheries Service
Galveston Laboratory to compile information relevant to studying the effects of
shrimp trawling on the Gulf of Mexico continental shelf. The purpose of this
project was to help identify data available to describe the continental shelf
of the Gulf of Mexico in order to delimit future research activities, not to
quantify previous research.

SUPPLEMENTAL INFORMATION: This data layer was prepared with ArcView 3.2, in a
non-projected format using decimal degrees for latitude and longitude. The data
layers were gathered from separate sources using various means of mapping and
having variable quality control. As a result, some of the layers may not
display exactly at larger scales. Since this project encompassed a Gulf-wide
scale, many of the layers contain neither perimeter nor area values. Attempting
to project these layers into an appropriate projection and then calculating
"accurate" area values is not recommended. Most of these data layers were not
designed for that purpose. Any calculations of this nature should be considered
only rough estimates. Users are advised to consult original publications and
data sources for exact data.

Quality
The NMFS Galveston Laboratory Fishery Ecology Branch compiled these data sets
in order to develop a scientific basis for refining essential fish habitat
designation for future amendments to fishery management plans. NMFS is not
responsible for any uses of these data sets beyond those for which they were
intended, and NMFS makes no claims regarding the accuracy of any data provided
by agencies or individuals outside NMFS.

Species are identified aboard the survey vessel immediately after catch.
Species that cannot be identified are frozen for later identification in the
laboratory. Integrated Taxonomic Information System (ITIS) is the current
(2002) authority for taxonomic classification. Historical species
identification data has been updated to use only current valid taxonomic
classifications in the Integrated Taxonomic Information System (ITIS). Full
taxonomic classifications can be obtained from ITIS.
