National Oceanic and Atmospheric Administration (NOAA) scientists from the Southeast Fisheries Science Center (SEFSC) and Atlantic Oceanographic and Meteorological Laboratory (AOML), working with scientists from the University of the Virgin Islands (UVI) in St. Thomas conducted a multi-year interdisciplinary research project which was a continuation of the 2007-2011 project using the NOAA Ship Nancy Foster to conduct biological and physical oceanographic surveys of the Virgin Island's (VI) bank ecosystems and surrounding regional waters as well as areas around Jamaica, Cuba and the Gulf of Mexico . The long-term sustainability of fisheries in the VI and surrounding regions is dependent on a comprehensive understanding of regional spawning aggregations, larval transport, and overall larval recruitment in the study area.

This survey sampled water properties, currents, and dispersal and transport of settlement-stage larvae in the VI and neighboring regions. Data in this archival package includes: processed larval fish data collected from the various net tows (BONGO, MOCNESS, etc.) , processed data from all conductivity, temperature, depth (CTD) casts, processed data from all lowered acoustic Doppler profiler (LADCP) casts, processed hull-mounted acoustic Doppler current profiler (SADCP), processed sea surface, flow-through data collected with the ship's thermosalinograph (TSG) and fluorometer collected aboard NOAA Ship Nancy Foster during cruises NF-15-02, NF-15-03, NF-16-02, NF-16-03, NF-17-03 and NF-18-03 from 2015-04-11 to 2018-06-24

To provide an understanding of regional spatial variation in the supply of settlement-stage fishes, and also insights into the relative importance of Grammanik Bank and its Marine Protected Areas as a source of juvenile fishes recruiting to the waters of the VI.

We measured seawater properties and collected icthyoplankton samples at sites in Puerto Rico, the USVI, and the BVI. Results from the survey should provide a better understanding of regional spatial variation in the supply of settlement-stage fishes between managed and non-managed areas across the region, as well as insights into the relative importance of Grammanik Bank as a source of juvenile fishes recruiting to the waters of the VI.

Atlantic bluefin tuna (ABT) is the highest-valued Atlantic tuna species on the market today. The species is an important export for American fishermen, with a majority of the product going to Japanese markets. The United States also imports ABT for consumption from a number of nations.

In an effort to improve our understanding of ABT spawning activity and the environmental conditions affecting the western Atlantic stock, we propose to sample areas adjacent to confirmed spawning grounds (the Gulf of Mexico) in the US EEZ. During FOCUS B of our 2015 research cruise aboard NF, we extended our annual ABT larval survey to the western Caribbean, the southeastern Gulf of Mexico, and Florida Straits in an effort to determine the extent of ABT spawning in this region. Additionally, we used adaptive sampling methods to further develop a larval habitat model. Identifying the relationships between ABT larvae and physical oceanographic gradients will greatly enhance current understanding of the early life history dynamics of this species. This work will also provide useful information on larval bluefin abundance and distribution for the entire Gulf of Mexico and western Caribbean. We anticipate that this work will reduce the variance in the calculation of the ABT larval index, which should lead to improved stock assessments across the region
