Abstract

This dataset contains data from the geographic information system (GIS) shapefile of recovered Florida manatee (Trichechus manatus latirostris) carcass locations within Florida from April 1974 through to the latest spatially verified data presently available. Locations are based both on coordinates provided by field staff (gathered either by geographic positioning system [GPS] or by using navigation charts to ascertain latitudes and longitudes) and maps provided by the field staff. Fish and Wildlife Research Institute (FWRI) GIS staff in the Marine Mammal subsection verify that the provided coordinates match the intent of the plotted location. Points representing carcass locations were entered into a GIS using a digital shoreline basemap taken largely from NOAA navigation charts (1:40,000) and from USGS quadrangles (1:24,000). The scale is considered to be 1:40,000.

Purpose

The primary use of this dataset is to display reported manatee carcass recovery locations and associated attributes, such as cause of death.

Supplemental information

Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI).

Counts were not available and filled with "1"; time was not available and filled with "00:00:00."

Attribute (table column)Description
oiddefinition not provided
objectidObject ID
countyCounty within Florida that the manatee carcass was recovered in.
obs_datetimeDate (time was not recorded and is 00:00:00)
fieldidUnique Field ID assigned to each manatee carcass recovered. This ID is used to identify the region of Florida, year and chronological order within that year for the region of Florida where the carcass was recovered. Exceptions include animals that were rescued, then died while in the care of an oceanaria facility, which include Sea World (SWFTm), Lowry Park Zoo (LPZ) and Miami Seaquarium (MSQ).
