NODC Accession 0107210 includes profile, biological and physical data collected aboard the ALBATROSS IV, ENDEAVOR, OCEANUS and SEWARD JOHNSON during cruises AL9306, AL9403II, EN268, OC301, OC303, SJ9503, SJ9505 and SJ9507 in the Gulf of Guinea, Mediterranean Sea - Western Basin, North Atlantic Ocean, North Pacific Ocean and Tyrrhenian Sea from 1993-05-22 to 1997-05-17. These data include SALINITY, HYDROSTATIC PRESSURE, SIGMA-THETA, FLUORESCENCE, Potential temperature (theta) and TRANSMISSIVITY. The instruments used to collect these data include CTD. These data were collected by Greg Lough and James P. Manning of National Marine Fisheries Service and Steve M. Bollens of Washington State University as part of GB. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-04-26. The following is the text of the abstract provided by BCO-DMO: The MOCNESS is based on the Tucker Trawl principle (Tucker, 1951). The particular MOCNESS system from which these CTD data came is one of three net systems. The MOCNESS-.25 carries nine rectangular nets (1/4-m2), usually with 64 micrometer mesh. In all three MOCNESS systems, the underwater unit sends a data frame, comprised of temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds. Temperature (to approximately 0.01 deg C) and conductivity are measured with SEABIRD sensors. Normally, a modified T.S.K.-flowmeter is used. Both the temperature and conductivity sensors and the flowmeter are mounted on top of the frame so that they face horizontally when the frame is at a towing angle of 45deg. Calculations of salinity (to approximately 0.01 o/oo S), potential temperature (theta), potential density (sigma), the oblique and vertical velocities of the net, and the approximate volume filtered by each net are made after each string of data has been received by the computer. (Wiebe et al., 1985) In addition, data were collected from four other sensors attached to the frame: the Transmissometer, the Fluorometer, the Downwelling light sensor, and the Oxygen sensor. A SeaBird underwater pump was also included in the sensor suite. It should be noted that whenever the data are of questionable value, 50.000 is written in the particular data field. Unless otherwise indicated, these data have not been post-processed. For additional information, contact the chief scientist (http://globec.whoi.edu/jg/serv/globec/gb/inventory.html0?project,name_prin) for the cruise or the U.S. GLOBEC Data Management Office (http://globec.whoi.edu/globec-dir/contact_dmo.html) (DMO). Note: Some variables have been eliminated from the display but are nevertheless available. These variables include: oxycurrent, oxytemp, tempco, and echo.

This dataset contains an ESRI Grid representing the rugosity of the bathymetry of an offshore portion of the NPS's Virgin Islands Coral Reef National Monument, south of St. John, US Virgin Islands, based on a 10m bathymetric grid. Rugosity is defined as the ratio of surface area to planar area and is used as a measure of benthic terrain complexity or "roughness". Rugosity values near 1 represent flat, smooth terrain, while higher values reflect increasing rugosity or terrain roughness. For rugosity grid interpretation, is is recommended that the grid be reclassified according to standard deviation divisions.NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the US Virgin Islands from 2/1/05 to 2/12/05. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9 as an XY event. Then the ArcToolbox conversion tool 'Feature to Raster' was used to generate an ESRI Grid of bathymetry. The Benthic Terrain Modeller (BTM) tool, a collection of ArcGIS terrain visualization tools developed by the Oregon State University (OSU) Department of Geosciences and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, was used to calculate the rugosity of that bathymetric grid. More information on the specific algorithms used can be found in the BTM's documentation.The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Hurricanes & Tropical Storms report focuses primarily on storms and conditions that affect the U.S. and its territories, in Atlantic and Pacific basins. The report places each basin's tropical cyclone activity in a climate-scale context. Key statistics (dates, strengths, landfall, energy, etc.) for major cyclone activity in other basins is occasionally presented. Reports began in June 2002. The primary Atlantic hurricane season (June-November) is covered each year; other months are included as storm events warrant. An annual summary is available from 2002. These reports are not updated in real time.

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

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 20120227 to 20120325, reef fish assessment surveys were conducted, as a part of Rapid Ecological Assessments (REA), during the Pacific Reef Assessment and Monitoring Program (RAMP) Cruise HA1201 in the Pacific Remote Island Areas region by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). During the cruise, 35 REA sites were surveyed at Johnston in the Pacific Remote Island Areas region. At each REA site, fish biologists entered the water and conducted a fine-scale (~700 m^2) and high degree of taxonomic resolution REA survey to assess and monitor species diversity, size distribution, and abundance of fish in shallow-water hard-bottom (less than 30 m) habitats. Reef fish assessment surveys were focused on cataloging the diversity (species richness), abundance (numeric density) and biomass (fish mass per unit area) of diurnally active reef fish assemblages. The stationary point count (SPC) method was used to quantify reef fish species. Two divers lay out a 30 m transect line, and position themselves at the 7.5 and 22.5 meter marks. The SPC biologist then records estimated size and abundance of all fish within a visually estimated 15-m diameter cylinder centered on the stationary diver (7.5-m radius, total area ~ 177m^2 per cylinder). The diver first spends 5 minutes identifying all fish species in the cylindrical area, then proceeds to count and estimate size (total length) for each in a series of "instantaneous" point counts or sweeps of the cylinder. Fish were identified at the species level, wherever possible. All reef-associated fish, including those in the water column, were surveyed. The survey time for each stationary point count survey was approximately 20 min and generally four stationary point count surveys (two per diver) were conducted at each fish REA site. After completing REA surveys, divers noted the presence, at the survey site, of any unusual fish species not counted during SPC counts, in order to facilitate species lists per location.
