2. Correlation of sea-surface temperature (SST) with sea-ice concentration (SIC) between Subarea 48.6 and other areas such as Ross Sea, Weddell Sea

   Abstract:  Since the correlation of SST between Subarea 48.6 and Division 58.4.2 was reported in ... and the Sea offPeru were re-analyzed in this paper. There is some correlation of SIC between Subareas ... 48.6 and 88.1 with SST data from 2002-2019. In addition, the correlation of SST and SST shifted forward ...

In contrast, mealing all waste had a marked effect on several of the bird groups. In particular ... observations on the second trial, the minced treatment suggested a reduction in the numbers of all albatross ...

5. A method for inferring movement rates of fish from mark–recapture data

   release and the recapture. In addition, the intensity of fishing effort (i.e. sampling) by location and ... distances approach. In addition, it also provides a way to generate a movement model that is parameterized ... required for the probability of recapture in a location to match the relative probability of catching an ... unmarked fish in that location. Clearly this may be related to the distance from the release point, but ...

8. The relative by-catches of taxa associated with vulnerable marine ecosystems by autolines and Spanish longlines

   Abstract:  We reanalyzed data collected by the longline fishery in Subarea 88.1 to compare the ... with each gear type, we attributed this difference to a difference in the rate at which VME taxa drop ... greater than Spanish bycatch at all depths represented in our data. Limiting the use of Autolines, which ... are in more intimate contact with the sea floor than Spanish longlines, may decrease bycatches of VME ...
