Objectives1. Physical oceanographic studies focused on the distribution of surface and sub-surface (to 600 m) water masses and the delineation of boundaries. Specifically, North Atlantic sub-tropical mode water (18°C Water) was studied in relation to the phase of the North Atlantic Oscillation (NAO).
2. Chemical oceanographic studies focused on the geographic distribution of nutrients (phosphate and nitrate), extracted chlorophyll-a, and pH. Sea surface pH was related to abundance, size, and shell characteristics of pteropods.
3. Biological studies focused on the geographic distribution of zooplankton, several meroplanktonic larvae including lobster (phyllosoma), eel larvae (leptocephali) and invasive lionfish larvae (Pterois volitans). Studies of pelagic Sargassum weed, associated fauna, and localized nutrient concentrations were examined using a modified Dip Net.
4. Geological studies focused on sediment distribution and shoaling in Samana Bay in relation to water depth, tidal cycle, and distance from shore.
