Evaluation of de la Mare’s composite standardised index for generating a simple time-series summary of many long-term datasets on Antarctic predators: consequences of missing values and criteria for inclusion of predator parameters
Abstract: In 1997, de la Mare presented a statistic (labelled the Composite Standardised Index at ... the Workshop on Area 48) to WG-EMM for generating a simple time-series index of many long-term ... datasets on Antarctic predators. The value of the index in a given year is dependent on the specific ... parameters present in that year. In this respect, the robustness of the index is dependent on that subset of ...

NET-BASED VERIFICATION OF ACOUSTIC TECHNIQUES USED TO IDENTIFY ANTARCTIC KRILL
Abstract: We validate the acoustic target classification protocols developed for the Stochastic ... that were collected during two cruises to the South Georgia region in 1996. For each krill aggregation ... sampled by net we calculated the difference between acoustic backscatter at 120 and 38 kHz (Sv120-38) and ... at 200 and 120 kHz (Sv200-120). We considered the performance of 4 different acoustic target ...
