Marine organisms have evolved in a viscous environment with a high heat capacity and solute concentrations similar to intracellular milieus, in which drag rather than gravity is the dominant force controlling movements. As a result, metabolisms, physiologies, and dispersal strategies of marine organisms are tightly coupled to oceanographic processes and features. Marine habitats are often defined on the basis of bottom structure which is relatively stable in space and time. However, oceanographic features including temperature, salinity, and current velocity are at least as important and often provide contexts for structural characteristics. These parameters are particularly important in determining the timing of formation, durations, as well as locations and volumes of critical habitats that ultimately control the production of marine resource species. Defining ecological habitat indicators for fishery resources is challenging due to the complex interactions between marine ecosystems and the physical forcing of key oceanographic features and processes. Ocean observatories now sample these critical variables at the broad spatial and fine temporal scales required to describe the effects of spatially dynamic ocean characteristics, enabling significant advances in the understanding of life history processes for living marine resources that use coastal ecosystems. As part of the U.S. Integrated Ocean Observing System (IOOS) program, partners in the Mid-Atlantic region along the United States east coast are developing a fully regional scale ocean observing network. The Mid Atlantic Regional Ocean Observing System (MARCOOS) data footprint stretches along 1000 km of coastline from Cape Hatteras, NC to Cape Cod, MA offshore to the shelf break. This region covers a large part of the Northeast U.S. Continental Shelf Large Marine Ecosystem (LME) in which climate and fisheries are the primary driving forces (Sherman, 2003). MARCOOS brings three key technologies that allow for fine scale characterization of the coastal ocean in support of fisheries science, including the acquisition of data streams from U.S. and foreign satellites in space, a network of high-frequency radars deployed along the shore, and a fleet of robotic gliders flying beneath the ocean surface. Within this context we will discuss fisheries applications utilizing retrospective analysis, adaptive sampling, and technological advances extending AUV missions toward fisheries specific applications. These include, real-time support for adaptive larval and fisheries process studies within the observatory footprint, integration of acoustic telemetry receivers on regional glider surveys to describe spatial population structure, and the development of observatory based ecological indicators to support the spatial management of fishery resources.
