Beach debris survey Signy Island, South Orkney Islands 1999/2000
Abstract: During the 1999/2000 austral summer the tenth annual beach debris survey was carried ... from three study beaches. The debris was counted, measured and classified by type,material, mass and ... size categories. A total of 55 items weighing 10.78kg was collected. The number of items was 35% less ... than 1998/99, and the second lowest ever recorded. The total mass of the waste recovered has decreased ...

KPFM2, be careful what you ask for – you just might get it
Abstract: We have substantially revised the krill-predator-fishery model that was presented to ... the WG-EMM in 2005. The new version of our model is called KPFM2, and we have addressed all four of ... the changes which the WG-EMM indicated would be required to use the model for providing advice on the ... allocation of catch among the SSMUs (i.e., add seasonality, consider alternative movement hypotheses, add ...

Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
distribution from acoustic line-transect data. MaxEnt is founded on the bedrock of probability theory and ... allows the most efficient possible use of known data in the inference process. The method takes explicit ... account of spatial correlation in the observed data and seeks to reconstruct a distribution of density ... across the whole survey area that is both consistent with the observed data and for which the entropy is ...
