This metadata record describes the LiDAR data that was collected for 147 square miles within part of Flagler County, Florida during 28 February - 5 May 2004. In 2008, because the final lidar dataset satisfied the accuracy requirements in the FDEM Baseline Specifications, the lidar data was processed into .LAS files, and breaklines and contours were generated for the Florida Division of Emergency Management (FDEM) using the existing lidar data from 2004.

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 3 September - 1 October 2005, marine invertebrate quantitative assessments were conducted, as part of Rapid Ecological Assessments (REA), during the Reef Assessment and Monitoring Program (RAMP) Cruise OES 0511 in the Marianas Archipelago. Such cruises are conducted at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). At specific reef sites, marine invertebrate zoologists along with coral and algal biologists entered the water and conducted a fine-scale (~100 m2) and high degree of taxonomic resolution benthic REA survey for coral, algae, and key invertebrate species. Invertebrate surveys were focused on quantifying key non-coral invertebrate species common to the reef habitats, and were conducted using a combination of different survey techniques to quantify the diverse communities. These methods included belt-transect surveys, roving-swim surveys, and quadrat surveys. In belt-transect surveys, quantitative counts of key invertebrates were recorded along two consecutively-placed 25m long and 2m wide belt transects (total area = 100 m2). For any species that cannot be identified in the field, a photograph and a representative specimen, if possible, is collected for later identification. Roving-swim surveys were conducted in the general area with the goal to collect qualitative data for rare, larger, and cryptic organisms, such as Crown of Thorns Starfish and Triton's Trumpet snails which may not be seen during belt-transect surveys, and to survey any additional habitats present at the site, e.g. sand, sea grass, pavement, etc. This was accomplished by swimming a zig-zag pattern that extends roughly 5 m on either side of the two transect lines (total length = 500 m). Quadrat surveys were used to quantify the smaller, more cryptic invertebrates which were sometimes overlooked or too numerous to count during belt-transect surveys. Ten 0.25-m2 quadrats were laid out at 2-m intervals along two of the 25-m transects (total area = 5 m2). For each quadrat the percent cover of sponges, octocorals and zoanthids was recorded, as well as urchins, hermit crabs of the genus Calcinus, trapezid crabs, and coralliophilid snails. In addition, up to 25 cm diameters of all urchin species are measured. Based on data from previous REA surveys, a group of target invertebrate species was chosen for quantitative counts at 8 REA sites at Saipan Island in the Marianas Archipelago. The species in the list were chosen because they have been shown to be common components of the reef habitats and they are species that are generally visible (i.e.; non-cryptic) and easily enumerated during the course of a single 50-60 minute SCUBA survey.

Bathythermograph data were collected from the HUMBOLDT within a 1-mile radius of Ocean Weather Station C (5245N 0350W) and in transit. Data were collected by the United States Coast Guard from 05 January 1965 to 21 January 1965. The platform was equipped and staffed to observe weather and sea conditions. 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 the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

The NOAA WAVEWATCH III® hindcast dataset comprises output fields from the monthly WAVEWATCH III® hindcast model runs conducted at the National Centers for Environmental Prediction. Each model run produces a collection of files containing gridded fields comprised of input and mean wave parameters such as the significant wave height, directions, frequencies etc. Once per month, a wave simulation is carried out using restart files from the previous month and forced by hindcast wind products for the entire month. The resulting output data are transferred to NODC on a monthly basis. NODC assembles the series of files into monthly accessions to facilitate archival retention and public access. The fields are encoded in the standard GRIdded Binary version 2 (GRIB2) file format. Wave spectral data summaries are included, as well as detailed spectra at selected locations, in tabular text format. Nine different sets of output fields, corresponding to nine different grids used in the numerical simulations, are included. These include a global grid, as well as regional and coastal grids covering much of the North Atlantic and North Pacific oceans.

The marine algae, invertebrate and fish communities were surveyed at ten islet or offshore island sites in the Main Hawaiian Islands in the vicinity of Lanai, (Puu Pehe and Poo Poo Islets), Maui (Kaemi and Hulu Islets and the outer rim of Molokini), off Kaulapapa National Historic Park on Molokai (Mokapu, Okala and Namoku Islets) and Oahu (Kaohikaipu Islet and outside Kapapa Island) in 2007. Survey protocol at all sites consisted of an initial reconnaissance survey on which all algae, invertebrates and fishes that could be identified on site were listed and or photographed and collections of algae and invertebrates were collected for later laboratory identification. Following the reconnaissance surveys, quantitative estimates of coral and algal coverage and size and biomass of fishes along 25 m transects were conducted at each site and their locations were recorded using GPS. This dataset consists of the photographic images from this project. In a separate NODC Accession, 0042684, quantitative results in spreadsheets are provided. The images could serve useful as new software becomes available for assessing coral and algae types and coverage via digital photographs.

This image represents a LiDAR (Light Detection & Ranging) 5x5 meter resolution bathymetric surface for an area surrounding the mouth of Salt River Bay (SARI)St. Croix in the U.S. Virgin Islands (USVI). The image's horizontal coordinate system is NAD83 UTM 20 North, and depth values are in meters referenced to Mean Lower Low Water (MLLW) heights. Fugro LADS, in collaboration with NOAA's NOS/NCCOS/CCMA Biogeography Branch, the University of New Hampshire and the National Park Service, acquired bathymetry, relative seafloor reflectivity and hyperspectral imagery in St. Croix from 2/21 to 2/22/2011. Hyperspectral data were acquired using a Hyspex VNIR-1600 sensor. Bathymetry and reflectivity data were acquired using a LADS (Laser Airborne Depth Sounder) Mark II Airborne System from altitudes between 1,200 and 2,200ft at ground speeds between 140 and 175 knots. The 900 Hertz Nd: YAG (neodymium-doped yttrium aluminum garnet) laser (1064 nm) acquired 5x5 meter spot spacing and 200% seabed coverage. In total, 1.62 square kilometers of LiDAR were collected between 0 m and 34 m in depth. Environmental factors such as wind strength and direction, cloud cover, water clarity and depth influenced the area of data acquisition on a daily basis. The data was processed using the LADS Mark II Ground System and data visualization, quality control and final products were created using CARIS HIPS and SIPS and CARIS BASE Editor. All users should individually evaluate the suitability of this data according to their own needs and standards.
