Abstract

Abstract of the Thesis The role of submarine groundwater discharge (SGD) on the water quality in Jamaica by Stivaly Paulino Master of Science in Marine and Atmospheric Science (Marine Geology) Stony Brook University 2017 To aid ecosystem management in fish sanctuaries along the northern coast of Jamaica, West Indies, it is necessary to locate and categorize submarine springs. Continuous shoreline surveys of 222Rn were conducted in Discovery Bay (18.469, -77.415), Turtle Crawl (18.176, -76.422) and Cold Harbour (18.174, -76.404) with simultaneous aerial thermal infrared imagery. Elevated 222Rn activities corresponded with plumes of cooler water at the shoreline indicative of submarine groundwater discharge (SGD), both from diffuse sources and from submerged springs. Distinct plumes of cooler water were not associated with stream discharge and measured 2 to 3 °C cooler than ambient surface seawater. Elevated 222Rn activities of 570 Bq m-3 in the plumes could be enriched over ten-fold above ambient open water activities of about 30 Bq m-3 but plume values were only about a tenth of end-member concentrations which were measured at ~5700 Bq m-3. Heterogeneous and variable SGD, and any associated contaminant load, has the potential to impact water quality in marine parks, conservation areas and marine and fish sanctuaries. | 63 pages
