1. Milk fatty acid signatures indicate both major and minor shifts in foraging ecology of lactating Antarctic fur seals

   Abstract:  Fatty acid signature analysis is based on the conservation and unique signatures of fatty acids in the marine food chain and it may be useful in determining the composition of seal diets or in detecting changes in diets. We apply fatty acid signature analysis to milks collected from

2. Dietary segregation of krill-eating South Georgia seabirds

   Abstract:  The diets of six of the main seabird species (two petrels, two albatrosses, two penguins) breeding at Bird Island, South Georgia were studied simultaneously during the chick-rearing period in 1986. For five species, Antarctic krill Euphausia superba was the main food (39-98% by mass);

3. Development of the krill stock in the elephant island region during the 1996/97 season

   Abstract:  During December 1996 the Elephant Island standard grid was surveyed for krill and salps. Krill and salps were present at almost all of the stations, other epipelagic zooplankton species were relatively scarce. Maximum krill density exceeded 7350 juvenile krill per 1000 m3. In general

4. Consumption of krill by minke whales in Areas IV and V of the Antarctic

   Abstract:  The consumption of Antarctic krill (Euphausia superba) by the southern minke whale (Balaenoptera acutorostrata) in Areas IV and V of the Antarctic was estimated from diurnal change in the forestomach content mass, standard metabolism and the body mass increase methods based on JARPA (the

5. Interannual changes in body fat condition, stomach content mass and distribution of minke whales in Antarctic Areas IV and V

   Abstract:  As an indicator of body fat condition, interannual variability in girth of minke whales (Balaenoptera acutorostrata) was analyzed in relation to sea-ice extent, stomach-content mass and distribution of minke whales in Antarctic Areas IV (70°-130° E) and V (130° E-170°W) from 1989/90 to

6. Establishment of a cemp monitoring program at Bouvetøya

   Abstract:  A CCAMLR Ecosystem Monitoring Program (CEMP) has been initiated by Norway at Bouvetøya, South Atlantic Ocean. A permanent research station was established at the CEMP site, Nyrøysa, on the western coast of the island during the 1996/97 field season. Species included in the monitoring

7. Preliminary results from CEMP monitoring of Antarctic fur seals, chinstrap penguins and macaroni penguins at Bouvetøya 1996/97

   Abstract:  A CCAMLR Ecosystem Monitoring Program (CEMP) was initiated at Bouvet0ya, South Atlantic Ocean, during an expedition to the island from 9 December 1996 to 22 February 1997. A research station was established at the CEMP site, Nyrøysa, on the western coast of the island. Species included

9. Catch per unit effort data from the early years of commercial krill fishing operations in the Atlantic sector of the Antarctic

   Abstract:  Catch Per Unit Effort data are presented from krill fishing operations in CCAMLR Subareas 48.1, 48.2, 48.3 for the period 1975/76 to 1987/88. Comparisons are carried out between Subareas in single years, between years on a Subarea and Area basis, and between oceanic and shelf regions.
