This project is to make laboratory measurements of the target strength (TS) of Pacific hake (Merluccius productus) as a function of frequency and the angle of orientation.The specific tasks include the following: 1. Calibrate the sonar at the Henderson Acoustic Facility at the Applied Physics Lab (APL) at the University of Washington (UW). 2. Conduct measurements of target strength (TS) of Pacific hake swimbladders at frequencies 15 kHz to 40 kHz vs. all angles of orientations (4solid angle, alone with swimbladders inflated with a number of different air volumes that may reflect the variation in swimbladder volume at different depths or pressures), and process and analysis the data. The project involves collaborative research activities. Drs. Dajun Tang and Darrell Jackson, and Russell Light at the APL will be funded by the NWFSC ($90K) to conduct the experiments and analyze the data. Larry Hufnagle and Dezhang Chu (NWFSC) will provide fish (hake) and assist with the experiments. We expect to obtain information of hake TS as a function of frequency and angle of orientation, and write a peer-reviewed paper. Although this project has ended officially, the analysis and publication effort will by continually funded by APL/UW. Raw acoustic data

Sanborn Map Company completed the original classification of the multiple return LiDAR of Berkeley County, South Carolina in 2009. In 2013, Dewberry was tasked with reviewing and updating the original LiDAR product. The nominal point spacing for this project is 1.4 meters. Dewberry used proprietary procedures to update and reclassify the LAS according to updated project specifications: 1-Unclassified, 2-Ground, 7-Noise,8- Model Key Points, 9-Water, 10-Ignored Ground, 13- Points removed from bridges and culverts (which were moved to class 15 at OCM).

Description

XBT data were collected from the NOAA Ship SURVEYOR in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the National Ocean Service (NOS) from 27 September 1976 to 22 October 1976. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

Data from Coral Reef Ecosystem Division (CRED), NOAA Pacific Islands Fisheries Science Center (PIFSC) Sea Surface Temperature (SST) Buoys provide a time series of surface water temperature at coral reef sites. The SST buoy (Model SST-001, Sound Ocean Systems, Inc., www.soundocean.com/index.htm) with external temperature recorder (Sea-Bird Model SBE39, Sea-Bird Electronics, Inc., www.seabird.com) telemeters a subset of the daily data in Near Real Time (NRT) via a Telonics ST-13 or ST-20 ARGOS PPT transmitter and internally records higher resolution temperature data from the SBE39, typically at a 600 second sampling interval for a duration of 2 years. This record refers to the internally recorded (high resolution in situ) SBE39 temperature data. When a SST buoy is recovered, a new one is typically deployed in the same place. Time series data combining multiple deployments from a given site may also be available. Please contact CRED with any questions.

Description

Towed-diver surveys (aka. Towboard surveys) are conducted by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center (PIFSC) as part of biennial Pacific Reef Assessment and Monitoring Program (RAMP) Cruises. These cruises support NOAA Coral Reef Conservation Program (CRCP) long-term goals for sustainable management and conservation of coral reef ecosystems. 7 towboard surveys (17.7188 km in length), were conducted at Molokai Island in the Main Hawaiian Islands from July 27 - August 20 2006 as part of RAMP Cruise HI0610. Towboard surveys are a good method for obtaining a general description of large reef areas, assessing the status of low-density populations of large-bodied reef fish, large-scale disturbances (e.g., bleaching), general distribution and abundance patterns of macro-invertebrates (e.g., COT, giant clams), and for assessing trends in these populations and metrics. A pair of scuba divers (1 fish and 1 benthic diver) are towed 60 m behind a small survey launch at a speed of 1-2 knots and a depth of approximately 15m. Each survey is 50 min long, covers about 2 km of habitat, and is divided into ten 5-minute survey segments. The fish diver records, to the lowest possible taxon, all large-bodied reef fishes (>50cmTL) seen within 5m either side and 10m in front of the towboard. Length of each individual is estimated to the nearest cm. The fish towboard is also outfitted with a forward-facing digital video camera to record the survey swath. The benthic diver records percent cover of coral and macroalgae, estimates benthic habitat type and complexity, and censuses a suite of benthic macroinvertebrates including Crown of Thorns sea stars and sea urchins. The benthic towboard is equipped with a downward-facing digital still camera which images the benthos at 15 second intervals. These images are analyzed for percent cover of coral, algae, and other benthic components. Both towboards are equipped with SEABIRD SBE-39 temperature/depth sensors set to record at 5 second intervals. Latitude and longitude of each survey track is recorded at 15 second intervals using a Global Positioning System (GPS) receiver onboard the tow boat. A layback algorithm is applied to more accurately map the position of the divers with respect to the reef environment. This algorithm calculates the position of the divers based on the position of the tow boat taking into account the length of the tow rope, the depth of the divers, and the curvature of the survey track. This metadata applies to the fish biomass observations.

Description

This archival package contains near-real-time ocean surface velocities, also known as total vector velocities, derived from HF radar stations. The velocities are arranged in a horizontal latitude/longitude grid. Measured velocities are indicative of the upper 0.3 - 2.5 meters of the ocean depending on the operating frequency and the vertical velocity profile of the water column. Data are in netCDF and velocities are reported in the Climate and Forecast (CF) compliant variables, surface_eastward_sea_water_velocity and surface_northward_sea_water_velocity. NDBC, which with SIO assembles data from the IOOS HF Radar Network, submits these data monthly to NCEI as part of NCEI's Integrated Ocean Observing System Data Assembly Centers (IOOS DACs) Data Stewardship Program. Remote sensing of ocean surface velocity from shore-based HF radar sites bridges the operational observational gap between point samples obtained from in-situ sampling and synoptic scale relatively low resolution data obtained from satellites by providing continuous mesoscale coverage at relatively high resolution near the coast.

Gridded multibeam bathymetry is integrated with bathymetry derived from multpectral World View-2 satellite data. Gridded (5 m cell size) multibeam bathymetry collected aboard NOAA Ship Hiialaka'i and R/V AHI. Multibeam data were also collected aboard the NOAA Ship Oscar Elton Sette in 2010, a 224’ (68 m) United States National Oceanographic and Atmospheric Administration research ship. Bathymetry values shallower than ~20 m were derived by gauging the reletive attenuation of coastal, blue, green and yellow spectral radiance as a function of depth. A multiple linear regression analysis of coastal,blue, green and yellow band spectral values against depth determined the variables of y-intercept, coastal,blue, green and yellow slope values. Variables then used in multivariate slope intercept formula to derive depth. Digital image processing to derive depths conducted with the ENVI 4.8 software program while data editing and integration was performed using ArcGIS 10. This data set is for the shelf environment of Rota Island, Mariana.
