The indicators for the animal life in the sea (the marine fauna) provide some information on the state of this life in Svalbard, on Bj\u00f8rn\u00f8ya and Jan Mayen, and in surrounding waters. The monitoring concerns seabirds, marine mammals, commercially exploited fish stocks and zooplankton.<\/p>\n\n\n\n
