Analysis of acoustic data for the 1994 Krill Flux Workshop
Agnew, D.J.
Abstract:
A methodology is described which when applied to data from an acoustic survey will yield mean krill density along an arbitrary section through the survey area, giving results compatible with the specifications given in wg-krill-93 Appendix D. A program written to calculate such sections is also described and example output displayed. A similar program calculates current speeds normal to a Read More

Use of current velocity data from FRAM to investigate the large scale transport of krill in the Scotia Sea
Murphy, E.J.
Abstract:
Current velocity data from a single time realisation of the FRAM model are presented for particular areas of the Scotia Sea. The regions are based on the CCAMLR sub-areas and also include a more detailed area around South Georgia. Mean current velocities have been calculated for region boundaries over the upper 250m of the water column. These have been combined with estimates of krill density Read More

Large scale circulation in the South Atlantic: estimates from giant iceberg drift rates
Trathan, P.N. and C. Symon
Abstract:
The paper reports work currently in progress and presents estimates for ocean circulation in the Scotia Sea. The estimates are derived from the drift rates of giant icebergs calved in the Weddell Sea since 1974. Comparison with other estimates is limited by the lack of studies reported in the literature, however, efforts to make these comparisons are in hand.

Stream lines in the FRAM velocity field: speeds and directions from passive tracers
Murphy, E.J.
Abstract:
A single time realisation of the FRAM model has been used to obtain trajectories of passive tracers. This note presents some of the analyses to provide background information on the potential transfers of krill in the Scotia Sea. More detailed presentation of the stream lines in the South Georgia region are also reported.

Tracer trajectories from the western shelf of South Georgia: ship displacement data
Murphy, E.J., I. Everson and C. Goss
Abstract:
Corrected ships heading data were used to calculate drift data for the shelf area to the west of South Georgia. The data were collected over a six-week period during 1986. A distance weighted interpolation was used to obtain tracer trajectories in this irregular data grid. The vector field is complex with no simple flow field. These data include a lot of complex process interactions. Particles Read More
