- Abstract:
- Aerial distribution surveys are used by marine mammal biologists from FWC and other agencies to determine the seasonal distribution of manatees. Most surveys are conducted from small, four-seat, high-winged airplanes (Cessna 172 or 182) flying at a height of 500-1000 ft at a speed of 70-90 kts. Small helicopters may be used instead of fixed wing aircraft in urban areas or where waters are particularly opaque and hovering may be required. Flights are usually five hours long and are most commonly flown every two weeks for six months. The surveys are designed to maximize the manatee counts by concentrating on shallow nearshore waters around the state where manatees and their primary food source, sea grasses, are located. Flight paths curve parallel to the shoreline, and the airplane circles when manatees are spotted until a count of the number of animals in each group is obtained. Offshore waters are usually not surveyed. Dolphin and sea turtle sightings are recorded opportunistically. All aerial data are recorded on paper maps and entered into a GIS shapefile for spatial analysis. GIS is a computer software system for representing data spatially and for conducting spatial analyses. Surveys of Volusia County (Tomoka River) were flown twice a month from May to November 1985. Staff from FWC, USFWS Sirenia Project, Brevard County and Hobe Sound NWR were observers for these flights. This survey was flown as a part of a larger study that included six east coast counties divided into five survey segments from north to south; Volusia and N. Brevard counties were within segment 1. The survey area includes the Tomoka Basin and Tomoka River.
- Purpose:
- To determine the seasonal distribution of manatees in Volusia County (Tomoka River), FL.
- Supplemental_Information:
- --Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.--

- Methodology_Description:
- Surveys were conducted 2 days per month for six months unless otherwise noted in the completeness report, covering all of the manatee's habitats in Volusia County. Most surveys are conducted by FWC staff from Cessna 172 aircraft at 500-1000 ft and 70-90 kts.
- Process_Step:
- Process_Description:
- After the survey, sightings are assigned a unique ID number, and data are digitized as points into a GIS shapefile. For surveys with two observers, all sightings from the primary observer's maps are digitized. Any additional sightings from the secondary observer's maps are digitized. In cases where both surveyors recorded the same sighting, the number of adults and calves recorded by the primary observer was entered into the shapefile. The location of the point and the attribute information are verified after digitization. The location of the point and the attribute information are verified after digitization. Sightings were plotted in reference to the FWC-FWRI Wildlife Research Marine Mammal section 40K shoreline. This dataset is subset to only include manatee sightings, though sea turtle and/or dolphin sightings may have been recorded.
