15.2.2.4 Geographic Information System (GIS)
For the record of the geographic position of sighted animals, with reference to the
boat position, a GPS Map 76 and a GPS Map 60c (Garmin
®
) were utilized, in the
waypoint function. For posterior analysis and studies of the humpback whale
distribution along the time in the study area, a GIS environment modeling was
created, including important features such as the Brazilian coastline, bathymetry
and the plotted geographic coordinates of each sighting, in a digital nautical charter,
using the software Arc View GIS (version 3.1).
Fig. 15.10 A competitive group of humpback whales can be sighted during their breeding season.
This group composition is characterized by a central female and multiples escorts, engaged in
dispute behaviors, even including a ruff fight for a mate partner (Photo: Marcos Rossi-Santos/IBJ)
Fig. 15.11 Genetic studies of humpback whales worldwide have shown that a whale closely associated with a calf is its mother, an adult female, as the same way that singing and escorting are
behavioral roles performed only by males
