Operations during this 22-day expedition included collection of 47,899 square kilometers of seafloor bathymetry (40,108 in the U.S. Exclusive Economic Zone). During mapping operations, NOAA Ocean Exploration simultaneously collected EM 304 multibeam sonar bathymetry observations and Simrad EK60/EK80 split-beam fisheries sonar observations of biologic material in the water column, as well as Knudsen 3260 sub-bottom profiler observations of sub-seafloor geologic structure and sediment. Focused survey regions included closing bathymetric gaps in the Gulf of Alaska, California, and off the coast of British Columbia, Canada. An additional focused survey in the Cascadia margin off the coast of Washington improved data quality in a region of interest for geological hazards. The exploratory mapping operations conducted during this expedition provide initial characterization of the region, as well as data to support further exploration. All data associated with this expedition have been archived and are publicly available through the NOAA archives.\r\n \r\n \r\n The primary objective of the expedition was to explore deepwater areas in the Gulf of Alaska, Canadian EEZ, Washington, Oregon, and California to provide baseline information to support science and management needs. Briefly, this expedition sought to: collect high-resolution bathymetry in areas with no or low-quality mapping data, survey geological features in these areas to acquire a foundation of sonar and oceanographic data.\r\n \r\n \r\n \r\n \r\n \r\n NOAA National Centers for Environmental Information\r\n \r\n \r\n \r\n \r\n \r\n \r\n ncei.info@noaa.gov\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/contact\r\n \r\n \r\n NCEI Contact Information\r\n \r\n \r\n Information for contacts at NCEI.\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n pointOfContact\r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA/OAR/OER - Ocean Exploration and Research\r\n \r\n \r\n \r\n \r\n \r\n \r\n 301-734-1014\r\n \r\n \r\n 301-713-4252\r\n \r\n \r\n \r\n \r\n \r\n \r\n 1315 East-West Hwy, SSMC3, #10210\r\n \r\n \r\n Silver Spring\r\n \r\n \r\n MD\r\n \r\n \r\n 20910\r\n \r\n \r\n USA\r\n \r\n \r\n oceanexplorer@noaa.gov\r\n \r\n \r\n \r\n \r\n 8am-5pm, Monday through Friday\r\n \r\n \r\n \r\n \r\n \r\n resourceProvider\r\n \r\n \r\n \r\n \r\n \r\n \r\n Abby Letts\r\n \r\n \r\n NOAA/OAR/OER\r\n \r\n \r\n principalInvestigator\r\n \r\n \r\n \r\n \r\n \r\n \r\n notPlanned\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.ncei.noaa.gov/data/oceans/oer/video/graphic/EX2307-BrowseGraphic.jpg\r\n \r\n \r\n \r\n \r\n \r\n \r\n Pacific Ocean\r\n \r\n \r\n Gulf of Alaska; west coast of Canada, Washington, Oregon, and California\r\n \r\n \r\n place\r\n \r\n \r\n \r\n \r\n \r\n \r\n Earth Science > Oceans > Marine Environment Monitoring\r\n \r\n \r\n Earth Science > Oceans > Aquatic Sciences\r\n \r\n \r\n Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography\r\n \r\n \r\n theme\r\n \r\n \r\n \r\n \r\n Global Change Master Directory (GCMD) Science Keywords\r\n \r\n \r\n \r\n \r\n 2020-01-09\r\n \r\n \r\n publication\r\n \r\n \r\n \r\n \r\n 9.1\r\n \r\n \r\n \r\n \r\n NASA Goddard Space Flight Center, Earth Science Data and Information System\r\n \r\n \r\n \r\n \r\n \r\n \r\n https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords\r\n \r\n \r\n Global Change Master Directory (GCMD) Keywords\r\n \r\n \r\n The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

Meterological data: sensors that measure atmospheric properties. Oceanographic data: Sensors that measure the physical and/or chemical properties of the ocean. Sonar data: Single-beam and Doppler Speed. Winches data: three winches output line out, line rate and line tension.

Teledyne RDI's vessel-mounted Ocean Surveyor family of ADCPs continues to raise the bar, collecting detailed maps of the distribution of water currents and suspended materials through the water column and along the ship's path - at depths and resolutions previously considered unattainable. In real time, the ADCP is also used to aid in situ decision-making, to adapt field operations, and to understand current regime characteristics.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n WetLabs ECO FLNTU\r\n \r\n \r\n \r\n \r\n \r\n ECO FLNTU Fluorometer\r\n \r\n \r\n \r\n \r\n \r\n \r\n WetLabs\r\n \r\n \r\n \r\n \r\n \r\n \r\n 541-929-5650\r\n \r\n \r\n \r\n \r\n \r\n \r\n USA\r\n \r\n \r\n support@seabird.com\r\n \r\n \r\n \r\n \r\n \r\n \r\n http://www.comm-tec.com/Prods/mfgs/Wetlabs/Manuals/FLNTU_Manual.pdf\r\n \r\n \r\n Combination Fluorometer and Turbidity Sensor\r\n \r\n \r\n ECO FLNTU User's Guide\r\n \r\n \r\n information\r\n \r\n \r\n \r\n \r\n \r\n \r\n resourceProvider\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n ECO FLNTU Fluorometer\r\n \r\n \r\n \r\n \r\n fluorometer\r\n \r\n \r\n The WetLabs ECO FLNTU is a dual-wavelength, single-angle sensor for simultaneously determining both chlorophyll fluorescence and turbidity. \r\n It detects light scattered by particles suspended in water, generating an output voltage proportional to turbidity or suspended solids. \r\n Scaling factors are used to convert the voltage readings to values representing chlorophyll concentration and turbidity expressed in Nephelometric Turbidity Units (NTUs).\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n","source_transform":{"@type":"dcat:Dataset","accessLevel":"non-public","contactPoint":{"@type":"vcard:Contact","fn":"NOAA National Centers for Environmental Information","hasEmail":"mailto:ncei.info@noaa.gov"},"describedByType":"application/octet-steam","description":"From September 23 October 14, 2023 (Seward, Alaska to San Francisco, California), NOAA Ocean Exploration completed Seascape Alaska 6: Gulf of Alaska Transit Mapping (EX2307). Operations during this 22-day expedition included collection of 47,899 square kilometers of seafloor bathymetry (40,108 in the U.S. Exclusive Economic Zone). During mapping operations, NOAA Ocean Exploration simultaneously collected EM 304 multibeam sonar bathymetry observations and Simrad EK60/EK80 split-beam fisheries sonar observations of biologic material in the water column, as well as Knudsen 3260 sub-bottom profiler observations of sub-seafloor geologic structure and sediment. Focused survey regions included closing bathymetric gaps in the Gulf of Alaska, California, and off the coast of British Columbia, Canada. An additional focused survey in the Cascadia margin off the coast of Washington improved data quality in a region of interest for geological hazards. The exploratory mapping operations conducted during this expedition provide initial characterization of the region, as well as data to support further exploration. All data associated with this expedition have been archived and are publicly available through the NOAA archives.","distribution":[{"@type":"dcat:Distribution","describedByType":"application/octet-steam","description":"The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.
