Popis

The Integrated Science Data Management (ISDM) office processes oceanographic profiles reported for the world oceans in near real-time from the Global Telecommunications System (GTS) for the Global Temperature and Salinity Profile Program (GTSPP). These data also support the activities of the Ship of Opportunity Programme Implementation Panel (SOOPIP) and the WOCE Upper Ocean Thermal Program (WOCE UOT). The ISDM sends a copy of these data to the US NODC three times each week.

Popis

This project is a cooperative effort between the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment, the University of Hawaii, and Analytical Laboratories of Hawaii, LLC. The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerial photography, hyperspectral and IKONOS satellite imagery. The enhanced spectral resolution of hyperspectral and control of bandwidths of multispectral data yield an advantage over color aerial photography particularly when coral health and time series analysis of coral reef community structure are of interest. Depending on the type of instrument, a spectral imaging system can be utilized to see multiple colors from ultraviolet through the far infrared range. The AURORA hyperspectral imaging system collected 72 ten nm bands in the visible and near infrared spectral range with a 3 meter pixel resolution. The data was processed to select band widths, which optimized feature detection in shallow and deep water. Photointerpreters can accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor using a software interface such as the Habitat Digitizer.

Popis

These data represent data collected from the Shipboard Environmental (data) Acquisition System (SEAS), a program developed by National Oceanic and Atmospheric Administration (NOAA) to provide accurate meteorological and oceanographic data in real time from ships at sea through the use of satellite data transmission techniques. The system transmits data through either the Geostationary Operational Environmental Satellite (GOES) or the International Maritime Satellite Organization (INMARSAT C) satellites to NOAA for use in weather, climatological and ocean models. NOAA is actively participating in an international effort to increase the number of subsurface temperature observations in support of global oceanographic and climate studies. NOAA's Expendable Bathythermograph (XBT) program, SEAS, currently supports about 80 Voluntary Observing Ships (VOS). SEAS XBT data are archived by the National Oceanographic Data Center (NODC) on a weekly basis.

NCEI Accession 0130659 includes physical and profile data collected aboard the NAVIGATION RESPONSE TEAM 3 during project OPR-N338-NRT3-10 in the North Pacific Ocean from 2010-10-07 to 2011-01-18. These data include CONDUCTIVITY, HYDROSTATIC PRESSURE, SALINITY, SOUND VELOCITY, WATER DENSITY and WATER TEMPERATURE. The instruments used to collect these data include CTD. These data were collected and submitted by the NOAA Office of Coast Survey in support of hydrographic multibeam surveys to meet NOAA charting requirements.

Popis

The dataset consists of 115 CTD casts in the region north of Flemish Cap. Some casts cover the full water column, while others only cover the upper 1000 db. The CTD casts were obtained with a SeaBird SBE911+ system, measuring temperature (2 sensors), conductivity (2 sensors), pressure, beam transmission, height above the bottom, oxygen (2 sensors), and chlorophyll fluorescence. All sensors were sampled at 24 Hz. The data were processed using the SeaBird data processing software suite, SBEDataProcessing-Win32, and with software in MATLAB. A low pass filter, with time constant of 0.15 s, was applied to the pressure record. To account for the transit time between the temperature and conductivity sensors, the conductivity measurements were aligned with the temperature measurements using empirically determined time delays. The primary conductivity was delayed by 0.035 s relative to pressure (this is in addition to the advance of 0.073 s which is performed by the SeaBird deckbox during data acquisition, thus resulting in a net advance of 0.038 s). The secondary conductivity was advanced by 0.048 s (except for cast ctd001, which had the automatic deckbox advance value of 0.073 s applied. Thus the secondary conductivity from this cast was delayed by 0.025 s, giving a net advance of 0.048 s). The two oxygen voltages were advanced by 4 s relative to pressure. A correction for conductivity cell thermal mass effects was applied to both conductivity channels using the parameters recommended by SeaBird (alpha=0.03, 1/beta=7.0). The temperatures, conductivities, and oxygen voltages were then median filtered using a 7-scan window. A loop edit step was then applied, whereby portions of the cast in which the pressure was not changing sufficiently fast (0.2 dbar/s) were removed. This was followed by computation of salinity, potential temperature, potential density, sound velocity, geopotential anomaly, and oxygen concentration. Unfortunately, it was found that the SeaBird data processing module Derive used the primary temperature and salinity in computing both primary and secondary oxygen. Because there were several casts during which the primary temperature sensor intermittently failed, this resulted in loss of oxygen data. To get around this problem, the oxygen calculation was performed separately in MATLAB using the SeaBird algorithm and with primary/secondary oxygen computed using primary/secondary T and S respectively. Finally, the data from the downcast were averaged into 1 dbar bins. Further details of the CTD data processing can be found in the header portion of the individual cast files. The final data files contain raw sensor values (1 dbar bin averages) plus a number of derived variables (e.g. potential temperature, salinity, sigma-theta, oxygen). A full list of the output variables is contained in the header portion of the cast files. The casts were visually examined to determine the quality of the data from the 2 separate sensor suites (primary and secondary). A header line was placed in each file indicating the preferred sensor pair (PRIMARY or SECONDARY) if one was bad or whether both were of equal quality (BOTH GOOD).
