AB: One objective of the May 2004 pilot study for the Lagrangian Transport and Transformation Experiment (LaTTE) was to determine the relative advantages of studying the Hudson River plume within the spatial and temporal context provided by a research-friendly coastal ocean observatory. Towards this end, a shelf-wide observational backbone was locally enhanced with high-resolution relocatable systems in the New York Bight apex. The permanent backbone includes local acquisition of international satellite ocean color imagery, a network of long-range High Frequency radars, and a cross-shelf Endurance line occupied by an autonomous underwater glider. The higher resolution HF Radar, glider and mooring network was originally deployed in the vicinity of the Long-term Ecosystem Observatory, where it attracted a large number of scientists to coastal upwelling experiments conducted offshore Tuckerton, NJ from 1998-2001. With scientific interest in the series of coastal upwelling experiments having peaked and run its course through the publication phase, the high resolution systems were moved to the New York Bight Apex to hopefully repeat the cycle of attracting a variety of scientists to a specific interdisciplinary process study site. During the LaTTE pilot study, datasets from the nested observation network were assembled in real-time at a shore-based acquisition center, and high-resolution atmospheric forecasts were performed. Specific emphasis was placed on communicating the real time observatory data and forecasts to scientists on a pair of research vessels conducting a dye release with the associated physical, biological and chemical sampling. Observational results from the observatory will be reviewed, with specific emphasis placed on the observed response of the Hudson River plume to a windshift from upwelling to downwelling favorable winds in the middle of the pilot experiment. This includes a shift from a relatively weak plume flowing eastward along the south shore of Long Island to a much more distinct plume flowing southward along the New Jersey coast. The observatory results provide a spatial and temporal context for viewing the LaTTE dye release, chemical and biological results.
