Observations at sea

In order to assess the state of health of bird and marine mammal populations, it is essential to know how many birds and marine mammals there are (abundance) and where they live (distribution). In this way we can assess whether they are in sufficient numbers or whether they are in danger. Indeed, most of the classification of species in the Red Lists of the International Union for Conservation of Nature (IUCN) is based on knowledge of these two states of affairs.
