Regime Shifts and Recruitment in the Western and Central Pacific Ocean

while we were interested in decadal-scale variability and the existence of relatively stable states (i.e., regimes) with rapid transitions (i.e., shifts) between them. Our project had three components: first, data rescue of historical datasets on tuna diet in the Pacific and comparison with data collected in recent years; second, objective characterization of oceanographic variability and derivation of oceanographic indicators; and third, development of statistical models relating oceanographic variability to tuna recruitment. The first two components seek to improve our ecological understanding while the third seeks to apply that knowledge to improving stock assessments and projections.
