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 were: Cetaceans: - Atlantic spotted dolphin - Northern right whale - Standard Bottlenose dolphin Sea Turtles: - Green turtle - Hardshell - Kemp's ridley - Leatherback - Loggerhead This survey's transects are available in the 'SECAS91Efforts' table/shapefile. ESRI coverage and shapefiles are available for this data set.

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., <i>Balaenoptera</i> sp.).

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). notPlanned Lance Garrison NOAA Southeast Fisheries Science Center Primary contact lance.garrison@noaa.gov NA NA NA Lance Garrison owner NA zd_87 2025-07-31T14:03:52-04:00 dataset Garrison, L. 2013.
