2. Proposed revision to the estimation of fisheries footprints

   Abstract:  A revised approach to the estimation of longline fisheries footprints is presented. The ... method uses a data-derived estimate of the uncertainty around the locations of longlines to define a ... grid. The proportion of the area of each grid cell that is covered by buffered lines is then used as a ... footprint index.

6. Target strength of mackerel icefish (Champsocephalus gunnari) from a scattering model

   backscattered target strength (TS) of six mackerel icefish (Champsocephalus gunnari) of total length 26.8–35.0 ... cm, at 38 kHz. The model used computed tomography (CT) scans of fish to determine the sound speed and ... density throughout the fish and simulated the complex interaction of the incident sound wave with the ... applicable to fish of length 26–35 cm. Existing in situ TS estimates are for smaller fish (16–26 cm) and ...

   influence biological activity. We pursued daily transition of coastal polynyas in the Antarctic Peninsula ... area from 1978 through 1995 using images of sea ice concentrations by the satellite microwave ... observations. A typical polynya existed off the tip of the Peninsula in 1987 and 1991. In the such years, sea ... ice cover developed extensively. Inversely, the years of the narrow sea ice cover were 1988, 1989,1990 ...
