 ERD scientists have been collaborating with the Monterey Bay National Marine Sanctuary (MBNMS) to develop value-added data maps that describe representative conditions of ocean surface waters off Central California. These enhanced maps are based on long-term satellite-derived sea-surface temperature data and use a classification scheme to discriminate between different ocean signatures. MBNMS has incorporated these maps into their ongoing discussions with various stakeholders on the formation of marine protected areas in sanctuary waters. A description of this data product and its applications has been written up in a paper titled "Integrating Enhanced Satellite Data Maps into Coastal Management Efforts" by Petra Stegmann, David Foley, Chad King, Franklin Schwing, Holly Price, Steven Bograd, and Daniel Palacios.

Daniel Palacios has been collaborating in a multi-author, multi-national effort to compile historical blue whale information (sighting and catch positions) in the southern hemisphere, led by Trevor Branch of the University of Cape Town and funded by the IWC. Palacios's role is primarily to help explain whale distribution patterns in relation to oceanographic processes in the Southern Ocean.

Palacios also assisted Robert Emmett (NWFSC/Newport Lab) in acquiring satellite-derived products from SeaWiFS for use in a trophic model for predicting annual adult salmon run sizes. By incorporating data on chlorophyll-a concentrations and optical water clarity (as measured by the attenuation coefficient at 490 nm) for an ocean region off the Columbia River, Emmett hopes to account for variations in juvenile salmon predation success, which will improve the performance of the model.
