Abundance

What is line transect boat survey?

  • Go out on a boat and conduct a dolphin survey along fixed routes (i.e. transects) in different areas

  • Two researchers look for dolphins and keep track of the time, positions and other environmental conditions at the same time

  • Record information on group size, distance between the boat and dolphins, angle from the bow etc

  • Enter data collected from boat surveys into a specialized computer program called DISTANCE, which provides estimates of density and abundance of dolphins in the survey area
