"Regional Ecology and Coastal Hydrography"

Principal Investigator: Ann Bucklin (UNH)

"The objective of REACH is to document and understand the functional inter-relationships among the major elements of the planktonic assemblage in the waters of western Gulf of Maine. The planned field program will characterize the physical dynamics, nutrient availability, and phytoplankton and zooplankton assemblage. The long-term goal of this effort is to work toward a predictive index of harmful algal bloom (HAB) occurrences in near-shore waters of the western Gulf of Maine based on an integrated assessment of the planktonic community." (from REACH home page)

Samples are taken monthly along a cross-shelf transect in coastal waters offshore of New Hampshire (see locations on REACH home page). The CTD cast data served here are part of a full suite of measurements that occur at each station.
