Beach debris survey – Main Bay, Bird Island, South Georgia 2000/01
Abstract: During the eleventh year of standardised beach surveys of man-made debris at Bird ... Island, South Georgia, a total of 290 items were collected. This represents a 33.3% decrease on the total ... of 408 items recorded in 1999/00 and the lowest levels of summer beach debris (147 items) since the ... 1994/95 season. The difference between the number of items collected in the summer and winter months is ...

Histopathology of Antarctic krill (Euphausia superba) bearing black spots
onboard a krill fishing vessel in the winter of 2003 and 2006 in the South Georgia region, the Antarctic ... Ocean, approximately 2-5% of sub-samples of 100 krill bore small black spots. The black spots were most ... often found on the cephalothorax of the body. Three bacteria were isolated from these black spots, and ... classified into either Psychrobacter or Pseudoalteromonas by the sequences of 16S rRNA genes. Histological ...

Climate change and precautionary spatial protection: ice shelves
Abstract: Regional climate change is now known to be well established in the Antarctic ... , particularly in the Antarctic Peninsula region. One of the most evident signs of climate change has been ice ... shelf collapse; overall, 87% of the Peninsula’s glaciers have retreated in recent decades. Ice shelf ... may simply include species from areas that are immediately adjacent to the collapsed ice shelf ...

Comparison of NASC values calculated by swarm-based and grid-based acoustic data processing methods for Antarctic krill density estimation
Abstract: The one nautical mile integrated Nautical Area Scattering Coefficient (NASC) values of ... four surveys in 48.1 fishing area were calculated using both the swarm-based and conventional grid ... -based acoustic data processing methods. All parameter settings were consistent with the reports of SG ... -ASAM-2017 except that the dB difference window of Sv 120 kHz-Sv 38kHz is set 0 to 20 dB. And the two ...

A study of UK and Russian surveys using acoustics to augment trawling methods in shelf waters off South Georgia (Subarea 48.3)
. Both used acoustic and trawl methods, and this paper uses both datasets to explore the similarities and ... differences between the surveys and discuss how much of the variation between the vessels was due to ... differences in the gear used and how much was due to natural spatial/temporal variability of the stock. The ... acoustic surveys indicated that icefish were not only located near to the seabed, but that a significant ...

Krill aggregation characteristics: spatial distribution patterns from hydroacoustic observations. Polar Biology (in press)
Abstract: The distributional features and physical characteristics of some 1500 krill (Euphausia ... superba Dana) aggregations detected and sized acoustically in the south-west Indian Ocean are described ... . The aggregations were on average considerably smaller than elsewhere in the Antarctic. Aggregation ... biomass was log-normally distributed with a mean of 0.18 t. Only 3% of the aggregations were heavier than ...
