Seaglider SG005, an autonomous underwater vehicle, collected physical ocean data from the coastal waters of Washington and Oregon between August 21, 2003, and January 20, 2004. The glider measured temperature, salinity, and depth-averaged currents along sawtooth trajectories through the water column. Data is archived by NOAA's National Centers for Environmental Information under accession 0155930.
Gulf of Maine control points used to validate the accuracy of interpolated water density rasters. The dataset was created by NOAA NCEI, with points randomly selected from seasonal and yearly water density measurements at various depths. The data appears to have been last updated in 2004.
Research papers and socioeconomic data tables assess the economic benefits and costs of Marine Managed Areas in Hawaii. The dataset combines results from multiple studies conducted by NOAA researchers. Data collection and analysis occurred from 1998 to 2003.
Ground validation GPS point data for benthic habitat maps of the Mariana Archipelago. The data were collected through a cooperative project involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, BAE Systems Spectral Solutions, and Analytical Laboratories of Hawaii. The data were generated in 2004 to validate maps derived from IKONOS satellite imagery.
Physical oceanographic data collected by an autonomous Seaglider vehicle during a mission in the Gulf of Alaska. The dataset was created by the University of Washington and archived by NOAA's National Centers for Environmental Information. Measurements were recorded from November 5 to December 23, 2003.
1113 benthic habitat characterizations were collected via GPS field observations to validate coral reef habitat maps. This accuracy assessment data was produced through a cooperative effort involving NOAA's National Centers for Coastal Ocean Science, the University of Hawaii, BAE Systems, and Analytical Laboratories of Hawaii. The dataset was finalized in 2004.
NOAA_NCEI provides a survey assessing marine nonindigenous and cryptogenic species on coral reefs across five Hawaiian islands. The study recorded 486 total taxa from 41 survey sites, identifying only 26 nonindigenous species. Data collection occurred from November 2002 to November 2003 using a standardized rapid assessment method.
A two-year mark-recapture study from November 2001 to October 2003 tracked mangrove terrapins in Big Sable Creek, Everglades National Park. The dataset, collected by CEOS_EXTRA, provides capture histories from 5 sampling trips to estimate survival, capture probability, and abundance. It established the first baseline assessment for this species in the coastal Everglades.
NCEI Accession 0108077 contains discrete profile chemical and physical data from the MP-5, MP-6, and MP-9 cruises in the North Pacific Ocean. The dataset includes measurements of total alkalinity, dissolved inorganic carbon, salinity, and temperature collected from three research vessels between July 2002 and August 2003. These data were collected by Patricia L. Yager of the University of Georgia as part of the MANTRA/PIRANA (MP) project.
Collections from 2002-2003 at harbor and reef sites on four Hawaiian islands recorded 1039 marine taxa. The survey identified 112 introduced or cryptogenic species, representing 10.9% of total taxa. Data was collected by researchers and archived by NOAA's National Centers for Environmental Information.
Video products were collected during the 2003 Titanic expedition aboard the R/V Akademik Mstislav Keldysh and its MIR I and MIR II submersibles. The dataset was created by NOAA_NCEI and covers the period from 2003-06-22 to 2003-07-02. It documents an assessment of the Titanic wreck site.
Mid-Atlantic Bight oceanographic data includes current meter readings, CTD (Conductivity, Temperature, Depth) profiles, and fluorometer measurements. The dataset was collected via ship-based instruments over a four-day period in April 2003. Data were submitted by the University of Delaware Marine Laboratory.
Seaglider SG005 data contains physical ocean measurements collected by an autonomous underwater vehicle off the Washington coast. The dataset was collected by the University of Washington and archived by NOAA NCEI. Measurements were recorded during a 5-day mission from February 8 to 12, 2003.
Long-term monitoring from 1979 to 2003 assesses the recovery of mosses in Antarctica's Taylor Valley from human disturbances like walking tracks and sample removal. The dataset, compiled by SCIOPS, documents impacts from field seasons in 1979/80 and 1980/81, with recovery evaluations conducted in 1989/90, 1996/97, and 2002/03.
One-meter panchromatic and four-meter multispectral IKONOS satellite imagery was purchased to support coral mapping activities for Guguan Island in the Northern Mariana Islands. The project was a cooperative effort involving the National Ocean Service, the University of Hawaii, and Analytical Laboratories of Hawaii. The imagery was processed between 2001 and 2003 to minimize atmospheric and water column effects.
NOAA NCEI provides IKONOS satellite imagery for Agrihan Island in the Northern Mariana Islands. The collection includes one-meter panchromatic and four-meter multispectral data purchased to support coral reef mapping and GIS projects. This imagery was processed by a cooperative effort involving NOAA, the University of Hawaii, and Analytical Laboratories of Hawaii between 2001 and 2003.
NOAA NCEI provides one-meter panchromatic and four-meter multispectral IKONOS satellite imagery for Asuncion Island in the Northern Mariana Islands. The imagery was processed to minimize atmospheric and water column effects to support coral reef mapping and time series analysis. Data collection was a cooperative effort involving NOAA, the University of Hawaii, and Analytical Laboratories of Hawaii, with imagery purchased and processed between 2001 and 2003.
From 2001 to 2003, IKONOS satellite imagery was collected for Saipan in the Northern Mariana Islands. The project was a cooperative effort involving the National Ocean Service, the University of Hawaii, and Analytical Laboratories of Hawaii. The imagery includes one-meter panchromatic and four-meter multispectral data, processed to minimize atmospheric and water column effects for coral reef analysis.
IKONOS satellite imagery provides one-meter panchromatic and four-meter multispectral data for Anatahan Island in the Northern Mariana Islands.
