During certain points in the year there is an inflow of warm, saline water into the Isfjorden, which results in the circulation of water layers that foster the growth of plankton, which sustains large number of crustaceans. The crustaceans attract fish like the capelin and polar cod, which in turn draw seabirds and mammals.
Birds Only a few species of birds live in or visit the park, but the ones that are found here often gather in huge numbers. The birds found in Isfjorden include
Brünnich's guillemot,
little auk,
Atlantic puffin,
glaucous gull,
northern fulmar and
black-legged kittiwake. Other notable species recorded here are
barnacle and
pink-footed geese, and the Svalbard
rock ptarmigan. ==References==
