The Pelagic Habitat Analysis Module (PHAM) will provide an advanced information system that will enhance decision support systems currently at agencies managing pelagic fisheries and marine protected areas. PHAM will leverage streams of NASA research products from JPL and integrate this with multivariate datasets in support of agency marine resource management applications. PHAM will be a development of SSA¿s EASy marine GIS, that provides the computational and visualization tools to integrate scientific algorithms, satellite imagery, and field data for decision support, including fisheries oceanographic and tagging data. Proof of concept of enhanced DSS via PHAM will be provided by specific agency case study applications. PHAM will provide software for automated processing of satellite imagery and related environmental information for improved definition of the habitat of pelagic species. Such processing includes algorithms for EOF analysis of satellite imagery (SST, color, and altimetry), SST-based analysis of data from electronically tagged species, and bio-optical analysis of ocean color imagery. The information on habitat provided by PHAM will be incorporated into models of stock recruitment and stock assessment by managers of marine fisheries at the Inter-American Tropical Tuna Commission (IATTC) and NOAA¿s Southwest Fisheries Science Center (SWFSC). IATTC is responsible for management of tuna stocks in the eastern Pacific Ocean, while scientists of the NMFS Fisheries Ecology Division help manage the fisheries of Pacific blue and shortfin mako sharks of the California Current. PHAM will provide managers of marine sanctuaries informatics resources for habitat analysis to augment their GIS-based decision support systems. These tools are used to make decisions regarding reserve design, human impacts to the sanctuary, the distribution and health of protected species, and the environmental conditions that affect these species. Our collaborators consist of the Channel Islands National Sanctuary and the Papahanaumokuakea Marine National Monument. Both sanctuaries will apply PHAM to better define the habitat of resident species as well as to help determine whether local ecological changes are linked to regional climatic shifts. PHAM meets the national priorities of ecological forecasting and coastal management. It directly addresses the need to improve decision support for marine protection area management and marine fisheries assessment. In addition, PHAM directly address national calls for ecosystem-based management of living marine resources.
