  1. Some comments on the procedure for testing estimators of krill abundance which utilise survey data

    Abstract:  Since krill distributional data do show evidence of spatial correlation, estimators of ... performance in practice. Such studies require a simple method for computer generation of krill distribution ... " models of krill distribution are considered. These achieve overall spatial correlation by placing ... encouraging improvement in fits to the distribution of inter-swarm distances observed on the 1981FIBEX survey ...

    Abstract:  Data on the distribution and abundance of mid-trophic level organisms (MTLOs) in the ... mesopelagic zones, using sea surface temperature, time of day (day/night) and depth. The resulting models ... predicted backscatter reasonably well in the Pacific sector of the SO, and in an independent dataset in the ... Indian sector of the SO. Our predictive models may provide a tool for inferring abundance and ...
