Cycles, 22 The purse seine fishing ground, which we believe is the nursery ground for Eastern Pacific tuna, also matches the ocean’s largest site of CO2 release to the atmosphere. The upper panel shows maps field calculations of CO2 release from the atmosphere. Takahashi et al. (2002) The lower panel maps field simulations of CO2 from a biogeochemical climate model developed by Schmittner and co- workers.

Purse seine recording stations superimposed upon a climatological image of annual average oxygen concentration at 150 m depth. PHAM screen shots. The purse seine fishing ground (indicated by +) matches well surface waters where chlorophyll concentration exceeds 1 mg/m3 (upper panel) & overlies the hypoxic layer (lower panel).

11. The Holy Grail of Stock Assessment Models: Recruitment! We have now incorporated into PHAM EOF analysis of time series information from satellites sea surface temperature, chlorophyll, and height and NASA’s ECCO 2 3-dimentsional global circulation model. This analysis yields underlying patterns in spatial and temporal variability that are then compared by cross correlation analysis to the temporal patterns in recruitment. Adults[Age+1] Larvae JuvenilesRecruits[ Age]Adults[Age+i] Spawning Survival Survival is a function of food availability and predation (both natural and human).

12. EOF 1 st Seasonal spatial component & temporal expansion coefficient (right hand corner) EOF 1 st nonseasonal spatial component & temporal expansion coefficient We have developed an algorithm to predict the recruitment of yellowfin tuna based upon EOF extraction of patterns from time series of satellite imagery.

13. Correlation between temporal expansion coefficients and yellowfin recruitment lead to hypothesis of temporal evolution.

Convention for the Conservation of Antarctic Marine Living Resources Convention on the Conservation of Antarctic Marine Living ResourcesConvention on the Conservation of Antarctic Marine Living Resources) The Convention on the Conservation of Antarctic Marine Living Resources, also Commission on the Conservation of Antarctic Marine Living Resources, and CCAMLR, is part of the Antarctic Treaty System. The Convention was opened for signature on 1 August 1980 and entered into force on 7 April 1982 by the Commission for the Conservation of Antarctic Marine Living Resources, headquartered in Tasmania, Australia. The goal is to preserve marine life and environmental integrity in and near Antarctica.Antarctic Treaty SystementeredTasmaniaAustraliamarine lifeAntarctica

22. The hypoxic layer also shapes the distribution of the purse seine catch for each of the 3 species. Here we see that average yellowfin catch/month fished is largest in waters where the hypoxic layer is most intense. The dots are color coded catch with warmest colors indicating larger catch. The lowest concentrations of O2 at 150 m is dark blue and the highest are dark red.
