Cetacean occurrence near an offshore oil platform in southern Brazil
Information about cetaceans in offshore Brazilian waters is scarce, and oil-rigs could provide an important opportunity to obtain new data. The present work was conducted on the P-XIV oil-rig (Petrobrás) (26o46’02.2”S; 46o47’02.15”W), located on the border of the continental slope, in an area of 200...
