This image represents a 0.3x0.3 meter principal component analysis (PCA) surface for areas inside Fish Bay, St. John in the U.S. Virgin Islands (USVI). It was created by integrating eight topographic complexity surfaces (mean depth, standard deviation of depth, curvature, plan curvature, profile curvature, rugosity, slope, and slope of slope). The eight complexity surfaces were rendered, stacked and exported to create one image with several different bands (each band representing a specific complexity surface). This stacked image was transformed into its first three principal components using the "Principal Components Analysis" function in ENVI 5.0. The transformation reduced the dimensionality of the dataset by removing information that correlated among the different bands (i.e., complexity surfaces). The resulting PCA GeoTIFF was created to aid in the classification of benthic habitat inside Fish Bay, St. John.The original bathymetric surface used to derive the tographic complexity surfaces and PCA was collected by Fugro LADS and funded by the National Oceanic & Atmospheric Administration (NOAA). Bathymetry and reflectivity data were acquired between 1/29/2011 - 2/28/2011using 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 3x3 meter spot spacing and 200% seabed coverage. Depths between 3 and 40 m were surveyed, producing a 3x3 m bathymetry and 3x3 m reflectivity surface. These surfaces were resampled to 0.3x0.3 m to match the spatial resolution of the orthophotos collected by the U.S. Army Corps of Engineers in 2012. 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.

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

Data from Coral Reef Ecosystem Division (CRED), NOAA Pacific Islands Fisheries Science Center (PIFSC) Subsurface Temperature Recorders (STR) provide a time series of water temperature at coral reef sites. Data is typically collected at 1800 second intervals for a duration of 2 years using a SBE39 Temperature Recorder (Sea-Bird Electronics, Inc., www.seabird.com). When a STR 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. For program information see the web site http://www.pifsc.noaa.gov/cred/oceanography.php

Coral health and disease assessments were conducted along 2 consecutively placed 25-m transects, as part of Rapid Ecological Assessments conducted at 8 sites at Swains Atoll in the American Samoa during 22 February - 19 March 2008, aboard the NOAA Hi'ialakai Reef Assessment and Monitoring Program (RAMP) Cruise HI0802. Within an area of 1-3m on each side of both transect lines, each colony was inspected and every diseased/afflicted coral enumerated and identified to the lowest taxonomic level. For each affected coral the following information was recorded: colony size, type of affliction, area affected, percent live/dead, and severity of the affliction (mild = 1-10%, moderate = 11-25%, marked = 26-50%, severe = 51-75%, acute = 76-100%). Coral afflictions were classified into one of six general categories (following Willis et al., 2004) including: bleaching, tissue loss, black band disease, skeletal growth anomaly, predation, and other lesions. This latter category included algal overgrowth, as well as unidentified syndromes causing deterioration of scleractinian corals. Tissue samples of selected cases were procured for histopathological analyses. These data provide the basis for computing quantitative estimates of disease incidence and prevalence. Samples and photographs provide aid in further disease characterization and description. Histological tissue samples are traditionally fixed in a formaldehyde solution prior to preparation for processing and analysis.

XBT data were collected from the USCGC MIDGETT in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the US Coast Guard (USCG) from 04 May 1978 to 22 May 1978. 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.
