Sea turtles captured in various fishing gear (pound nets, long haul seines, gill nets) were outfitted with satellite transmitters so that their movements, migratory pathways and foraging behavior could be tracked. Despite their greater expense, satellite transmitters enable the researcher to determine long-range movements of sea turtles in comparison to acoustic and radio transmitters which delineate fine scale movements and habitat preferences. Furthermore, satellite transmitters have the capability of measuring and recording water temperature along with dive depth and duration of each tagged sea turtle. Finally, time spent on the surface can be measured and recorded.

To determine movements of green turtles in the nearshore foraging areas, we deployed acoustic tags and determined their movements through active and passive acoustic telemetry in San Diego Bay and the Long Beach area.

Coastal habitat use and residency of small juvenile Atlantic sharpnose (Rhizoprionodon terraenove) and bonnethead (Sphyrna tiburo) sharks in relation to larger juvenile blacktip (Carcharhinus limbatus) and scalloped hammerhead (Sphyrna lewini) sharks were examined by acoustic monitoring in Crooked Island Sound, FL. This is a raw dataset no analysis or publications have come from this data as of data.

Acoustic Tracking of Reef Fishes to Elucidate Habitat Utilization Patterns and Residence Times Inside and Outside Marine Protected Areas Around the Island of St. John, USVI NOAA's Biogeography Branch, National Park Service (NPS), US Geological Survey, and the University of Hawaii used acoustic telemetry to quantify spatial patterns and habitat affinities of reef fishes around the island of St. John, US Virgin Islands. The objective of the study was to define the movements of reef fishes among habitats within and between the Virgin Islands Coral Reef National Monument (VICRNM), the Virgin Islands National Park (VIIS), and Territorial waters surrounding St. John. In order to better understand species' habitat utilization patterns among management regimes, we deployed an array of hydroacoustic receivers and acoustically tagged reef fishes. Thirty six receivers were deployed in shallow nearshore bays and across the shelf to depths of approximately 30 m. We tagged 184 individual fishes representing 19 species from 10 different families with VEMCO V9-2L-R64K transmitters.

These datasets show acoustically detected fish densities throughout the Caribbean ocean. NOAA/NCCOS collected these datasets to help characterize broad-scale fish abundance, biomass, and understand temporal behavior. Acoustic data was collected aboard NOAA Ship Nancy Foster using 120-7C splitbeam transducer during cruise # NF08-01, NF09-01, NF10-03, NF11-01, NF12-01, NF13-01, and NF14-01. The hull mounted Simrad 120-7C transducer was calibrated to factory standards and environmental parameters where applied during acquisition. Data was collected using 128 microsecond pulse length and had a varied ping rate due to triggering from Reson 7125 multibeam system. The resulting data layers show geo-referenced fish densities per 100 square meter intervals. The fish densities have been divided into three size classes, small fish (<11cm), medium fish (11cm-29cm), and large fish (>29cm).

2013 Summer CalCOFI. The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish and Wildlife, NOAA Fisheries Service and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change. CalCOFI conducts quarterly cruises off southern and central California, collecting a suite of hydrographic and biological data on station and underway. Data collected at depths down to 500 meters include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR, C14 primary productivity, phytoplankton biodiversity, zooplankton biomass, and zooplankton biodiversity.
