    Field studies were carried out at Bouvetøya from 9 December 1998 to 27 February 1999. The main objective for the 1998/99 expedition was to continue the CEMP-monitoring work initiated in 1996/97. The species monitored were Chinstrap Penguin (Pygoscelis antarctica), Macaroni Penguin (Eudyptes chrysolophus) and Antarctic Fur Seal (Arctocephalus gazella). In addition to the CEMP-work, other work on seabirds and seals was carried out, including diving behaviour of penguins, and studies of diet and pup production of fur seals. The following CEMP-parameters were studied in Chinstrap Penguin and Macaroni Penguin: breeding population size (A3), age-specific annual survival and recruitment (A4), duration of foraging trips (A5), breeding success (A6), chick diet (A8), and breeding chronology (A9). For Antarctic Fur Seal, data were collected on the duration of adult female foraging/attendance cycles (C1) and pup growth (C2).
