NOAA Southeast Cetacean Aerial Survey 1992; SightingsEntry ID: seamap87
Abstract: Southeast Cetacean Aerial Survey, SECAS, was conducted in 1992 by NOAA Southeast Fisheries Science Center (SEFSC) to estimate Cetaceans abundance. This data set contains sightings of cetaceans and sea turtles as well as other species, including fish and shark, observed during the aerial survey. Marine mammals and sea turtles observed includes as follows.
<< Cetacean >>
Atlantic spotted dolphin
Northern right whale
Standard Bottlenose dolphin
<< Sea Turtle >>
Green turtle Hardshell
Survey's transects information is available in 'SECAS92Efforts.' Visual representation of this data set will be provided in the forms of ESRI's coverage and shapefile.
Purpose: The purpose of this data set was to collect Cetacean distribution data and allow for estimating Cetacean abundance in the Southeast. These abundance estimates were expected to serve as a basis for estimating Potential Biological Removals (PBR) for the species stocks in the region in support of Marine Mammal Protection Act (MMPA) requirements. More specifically, the survey was to obtain an index of ... abundance for Tursiops truncatus so as to detect population trends by comparison with historical abundance data (SETS).
SUPPLEMENTAL INFORMATION: Records with no common name are some pollution observed (e.g. plastic). Records were assigned a sequential number LineNo. LineNo can be used to match observations with corresponding transects, each of which has BegLineNo and EndLineNo fields. Observation records with their LineNo between BegLineNo and EndLineNo in a transect are related to that transect. A duplicated LineNo indicates more than one species were observed at the same time. Records include 'off-effort' sightings. Card 'D' indicates the observation was recorded while on-effort. Card 'F' indicates the observation was recorded while off-effort. When searching for a specific species, note that some records don't identify animals observed at a species level. If this is the case, the common/scientific name may be genus/family or higher (e.g. Balaenoptera sp.).
