Research Field Notes: No. 9



7/30/2014. Dolphin Boat Survey

Today’s survey extended from the Jupiter Inlet (N 260 56.624' W 800 03.805') down to the Lake Worth Inlet [aka the Palm Beach Inlet] (N 260 46.300' W 800 03.500').

Research Organization: Taras Oceanographic Foundation

Wind/Water conditions: S,SW 5. Seas 0-2’

Duration: 8am-3: pm

Dolphin encounters: Today we had several encounters during survey one. We saw a total of 25 tursiops; maybe 2 spotted. The first few encounters were brief. We had a very long encounter that lasted 1.5-2 hours. There were three cow/calf pairs and one matriarch with them; plus one lone male following them on the outside. We observed many behaviors. Tail slaps, belly up; rolls; long dives, short dives, travelling; acrobats and even some squeeks. The babies were playful, but the gatekeeper kept trying to distract us by crossing in front of the bow so we had to stop-- allowing the group to move away from us. Interesting. The (assumed) male just kept up off to the side following the entire time.

During Survey two: zero encounters. The wind and seas picked up, and as usual the rain was chasing us home early.
OTHER: Turtle counts:  6    Trash count:    5
