Rese­ar­chers are spy­ing on table man­ners of wha­les

Do mari­ne bio­lo­gists not alre­a­dy know about the fee­ding and migra­tio­nal beha­viour of hump­back wha­les? After all, the­se ani­mals are the best-stu­di­ed wha­les in the sou­thern hemi­sphe­re. So far, small data log­gers atta­ched to the ani­mals have sam­pled depth data, migra­ti­on rou­tes and water cha­rac­te­ristics. Now the­se litt­le aids can even pick up 3-D moti­on pat­terns and record under­wa­ter vide­os. Aus­tra­li­an and Ame­ri­can sci­en­tists were inte­res­ted in using the­se methods to find even more details about fee­ding beha­vi­or and food com­po­si­ti­on of the hump­back wha­les.

At the same time, they used their time in the field to fas­ten con­ven­tio­nal data log­gers to the dor­sal fin of min­ke wha­les. The­se wha­les live clo­se to the ice in the sou­thern sum­mer and litt­le is known about them. The sci­en­tists hope to gain more infor­ma­ti­on about this spar­se­ly stu­di­ed wha­le spe­ci­es. Mari­ne ani­mals that bene­fit from pack ice habi­tats are par­ti­cu­lar­ly affec­ted by incre­asing sea tem­pe­ra­tures, oce­an aci­di­fi­ca­ti­on and incre­asing strong winds.
