Otolith Chemistry Reflects Frontal Systems in the Antarctic Circumpolar Current
Pronounced environmental trends across fronts suggest that the otolith chemistry of oceanic fish can resolve zones on either side, promoting application to population questions at similar spatial scales. Trace and minor elements laid down immediately prior to capture—along the edges of otoliths from Patagonian toothfish Dissostichus eleginoides—discriminated frontal zones in the Antarctic Circu...
متن کاملOtolith Chemistry Indicates Population Structuring By The Antarctic Circumpolar Current
Large-scale transport of seawater in ocean currents may generate spatially complex population structure through the advection of life stages of marine fish species. To test this, we compared the chemistry of otolith nuclei from Patagonian toothfish (Dissostichus eleginoides), presently managed as spatially discrete populations corresponding to fishing management areas along the Antarctic Circum...

متن کاملTopographic meandering of Antarctic Circumpolar Current and Antarctic Circumpolar Wave in the ice‐ocean‐ atmosphere system
[1] Topographic meandering of Antarctic Circumpolar Current (ACC) is found to be an impediment in the propagation of Antarctic Circumpolar Wave (ACW) in the Indian Ocean sector of Antarctica. Reasons for this are attributed to the southward advection of the ACW anomalies associated with the topographic meandering of the ACC. The southward meandering of ACC facilitates warming up of the region e...
متن کاملAntarctic Circumpolar Current in coupled climate models
1 The transport of the Antarctic Circumpolar Current (ACC) varies strongly across the cou2 pled GCMs (general circulation models) used for the IPCC AR4. This note shows that a 3 large fraction of this across-model variance can be explained by relating it to the param4 eterization of eddy-induced transports. In the majority of models this parameterization is 5 based on the study by Gent and McWi...
