Archive of Updates and Forecasts


Below are links to previous updates of ocean ecosystem indicators and forecasts based on those indicators.  Semiannual updates are provided after data from spring sampling cruises has been collected and analyzed, and annual updates after September sampling and analysis is complete.  Data on adult returns is compiled as it becomes available and is reported along with recent adult return data.  Figures are not archived at this time, but many show cumulative information from all years for which we have data.
