Sabina Airoldi with the carcass of a common bottlenose dolphin found at sea
By "touching" the
dolphins with a special sponge on top of a long pole,
tiny
skin fragments can be collected for genetic
analyses
Dedicated
software developed by the International Fund For Animal Welfare (IFAW)
indicates the location of a sperm whale
During the phot-identification of sperm whales a
photogrammetry technique is also applied,
using a laser range finder. This technique enables to
estimate the body lenght of the individuals phptographed
Collection of faecal samples of sperm whales enable to investigate the species' feeding habits
A solitary fin whale is sighted
Passive tracking of a fin whale by using a laser range-finder
Collection of faecal samples of a fin whale
A
v-TDR (velocity-time-depth recorder) is attached to a fin whale by means
of a suction cup to investigate diving behaviour
A v-TDR attached to a pilot whale has shown its extraordinary diving capabilities
Researchers
and project participants analyse cetacean photos and
attempt
a preliminary identification of the individuals sighted at sea
