The Research
Our main research subject is the sperm whale, the largest of
the toothed whales and we are using photo-identification analysis (photo-ID)
to try and determine population size and migration patterns. Sperm whales
develop a unique pattern along the trailing edge of their tail due to fatigue
and this pattern can be used to identify individual animals.
Since 1993 we have identified nearly 600 animals and by comparing our photos
with the rest of the North Atlantic, we have found animals seen in the Azores
that have also been seen in the Canaries and Madeira.
Dolphins & Turtles
We also use photo-ID to identify bottlenose dolphin and so
far we have seen over 800 individuals. In summer 2000 work will start on photo-ID
of Risso’s dolphin as we have collected hundreds of photos of these animals
over the years. One of our sponsored students will be analyzing these photos
as part of his MS.c degree thesis. We are working with the Archie Carr Institute
in Florida to study the migrations of loggerhead turtles that pass by the
Azores.
These animals have lots of problems at the moment (natural and manmade) so
we hope the 6-7 minutes they are on board Physeter will help to provide vital
information on how to help them. In addition we record all sightings of marine
mammals we see (20 species so far identified) and keep a log of environmental
data for each day.
How You Can Help
Participating on one of our tours funds the
research we do so you do not have to
do any work while on board and you are free to sit back and relax.
We have a full crew on board taking care of all the chores and research and the atmosphere on board is very relaxed and informal.
