Madison-Swanson MPA reef fish video survey
공공데이터포털
The Southeast Fisheries Science Center Mississippi Laboratories conducts standardized fisheries independent resource surveys in the Gulf of Mexico, South Atlantic, and U.S. Caribbean to provide abundance and distribution information to support regional and international stock assessments. The reef fish survey of Madison-Swanson and Steamboat Lumps MPA is conducted primarily on the along topographic features (e.g. reefs, banks and ledges) of the MPA. A two-stage sampling design is used with the first stage or primary sampling units defined by geographic/geoform strata including ridges, pinnacles, rubble and sand flats and the second stage being randomly selected sites within the geoform strata. Sampling is conducted using a video camera array. No biological sampling is coupled with the survey because of the areas status as an MPA. The camera array consists of four housings positioned orthogonally and center mounted at a height of 51 cm above the bottom of the array. Each housing contains a pair of black-and-white Videre stereo cameras along with a color mpeg camera. Sampling of reef sites with video cameras occurs only during daylight hours, with the first gear deployment one hour after sunrise and the last gear retrieval one hour prior to sunset. Video arrays soak for 35 minutes. Habitat mapping was conducted using a multibeam echosounder by USGS. At each site hydrological data is collected using Conductivity Temperature Depth sensor (CTD).
Large Pelagic Logbook Trip Survey (Vessels)
공공데이터포털
This data set contains catch and effort for fishing trips that are taken by vessels with a Federal permit issued for the swordfish and sharks under the Highly Migratory Species (HMS) fishery management plan. Fishermen that own vessels with permits in these fisheries are required to complete a vessel logbook for every trip in which any species in the Highly Migratory Species fishery management plans are caught and landed. Fishermen are not required to report fishing trips in which other than these species are caught. However, fishermen are required to submit a no-fishing report if they did not fish for or catch any HMS species during a calendar month. In 1986, the Southeast Fisheries Science Center (SEFSC) initiated a logbook program for vessels that held a federal vessel permit to fish for swordfish in the Atlantic Ocean and Gulf of Mexico. In 1993, a similar program was initiated for vessels with a federal permit to fish for sharks that are included in the HMS fishery management plan. In order to provide sufficient level of detail for fishing effort by the longline vessels, the catch and effort data need to be reported for each longline set. Consequently, a single logbook form was designed for the fishermen to record the catch (numbers of animals caught) and effort, which includes data on the length of the longline, the number of hooks and the duration of the set. To reduce the number of times that fishermen need to record certain pieces of information, e.g., location of unloading, duration of trip, number of crew, a trip summary form was designed in 1999 that includes the trip-related information that is the same for every set. This redesign of the logbook form resulted in two forms, the trip summary and the set forms. Only one trip summary needs to be completed for each trip, but a separate set form needs to be completed for each longline set made during the trip. At the same time, additional questions were added to the trip summary form to collect information on the expenses that the vessels incurred during the trip. Initially, this information was voluntary and the fishermen did not have to provide the cost data whereas the catch and effort data are mandatory and the vessels permit will not be renewed if logbooks are not received for every trip where swordfish and/or sharks are caught and landed.
North Atlantic Right Whale Aerial Survey
공공데이터포털
The North Atlantic Right Whale Aerial Survey is a NOAA Fisheries program conducted by the Northeast Fisheries Science Center, which conducts aerial surveys to locate and record the seasonal distribution of North Atlantic Right Whales (Eubalaena glacialis) off the northeastern coast of the United States. The purpose of these North Atlantic Right Whale (NARW) aerial surveys is to monitor the population, track injury rates, and identify areas of entanglement and vessel collision risks. The Marine Mammal Protection Act (MMPA) and Endangered Species Act (ESA) mandates the National Marine Fisheries Service (NMFS) to evaluate the status of the NARW population and reduce mortality below the population's Potential Biological Removal (PBR) in order for the species to recover. A major component of the surveys is photo identification of individual right whales to estimate the population and its annual rate of mortality. Distance sampling data is collected for all large whale species during systematic aerial surveys of neritic waters of the eastern seaboard of the U.S. Additional aerial surveys are focused in areas of seasonal right whale occurrence. Right whale absolute density (individuals km2) is calculated from spatial, temporal, and environmental covariates, accounting for detectability differences between observation conditions, and corrected for perception and availability biases, whale dive behavior, group composition, and group size. Seasonal densities are calculated using covariate maps. When right whales are encountered, the aircraft breaks from the systematic trackline to circle and collect photographs of natural markings on the whales for individual identification using handheld digital cameras. Estimation of the NARW population is based on a state-space model of the sighting histories of individual whales constructed from the central photo-ID catalog curated at the New England Aquarium. Most of the population is photographically captured each year. The comprehensive capture effort provides small credible intervals to the population estimate, which in turn provides relatively precise estimates of annual mortality. High precision estimates of right whale mortality are critical to meet conservation goals. Photographic captures in specific areas over shorter periods can provide estimates of both local abundance and seasonal residency of individuals.

Atlantic Protected Species Assessment Aerial Surveys
공공데이터포털
These data sets include a compilation of aerial line-transect surveys conducted over continental shelf waters of the southeastern U.S. Surveys have been conducted intermittently since 1982. The majority of these surveys are targeted to assess the abundance and spatial distribution of bottlenose dolphins and sea turtles between Florida and New Jersey. Surveys are conducted in high-winged twin engine aircraft flying at altitudes of 600-750 feet. Visual observations of marine mammals, sea turtles, birds, and other species are recorded including species identifications, counts of animals. Surveys are conducted along line transects oriented perpendicular to the shoreline and follow protocols consistent with analysis using Distance approaches to estimate detection probability and abundance. These data have been used to provide abundance estimates for target species in annual Marine Mammal Protection Act Stock Assessment Reports.
