Abstract

Mid Atlantic Tursiops Surveys (MATS) were conducted in 1995 by NOAA Southeast Fisheries Science Center to examine the distribution and estimate an index of relative abundance for Atlantic bottlenose dolphins (Tursiops truncatus) inhabiting the nearshore coastal waters in mid-and southern Atlantic bight. This data set contains sightings of not only the target dolphins but also other species including cetaceans, sea turtles, fish and shark observed during the aerial surveys.
The same transects were traced three times on different dates during the survey period. This data set is the last one. The other two are provided, too, with the number following MATS95s indicating the first, second and last.
Cetacean and sea turtles observed included:
Cetaceans:
- Atlantic spotted dolphin
- False killer whale
- Standard Bottlenose dolphin
Sea Turtles:
- Hardshell
- Kemp's ridley
- Leatherback
- Loggerhead

This survey's transects information is available in MATS95s3Efforts.

Purpose

The purpose of this survey was to examine the distribution and estimate an index of relative abundance for Atlantic bottlenose dolphins inhabiting the nearshore coastal waters of the U.S. mid- and southern Atlantic bight.

Supplemental information

Records with no common name were observations of pollution (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 as well. Card 'F' indicates the observation was done while off-effort. Card D was used for observation while on 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.).

Attributes

Overview

Attributes described below represent those in the original dataset provided by the provider.
Only minimum required attributes are visible and downlodable online. Other attributes may be obtained upon provider's permission unless otherwise noted below.

The dataset contains information necessary to locate the species sightings observed in the survey. The structure of the dataset was defined by NOAA Southeast Fisheries Science Center. Note that the dataset is a subset of the larger, complete dataset collected in the survey which includes environmental information. The columns before LineNo are applied to the shapefile only. The following information is not included in the dataset but will be found in the master data. For details, please contact NOAA Southeast Fisheries Science Center. Track; Speed; GPS Status; Observers; Airplane altitude; Weather; Sea state; Turbidity; Sunlight; Glare; Water color; Water temperature; Sighting angle; Effort status.
