For this project, NOAA Ship Rainier will be operating around American Samoa and PRIA to conduct an extensive hydrographic survey to map bathymetry and habitat around the islands, pinnacles, and reefs in support of nautical charting and habitat mapping. With the collaboration and partnership of the National Centers for Coastal and Ocean Science (NCCOS), the National Coral Reef Monitoring Program (NCRMP), and the National Marine Fisheries Service (NMFS), this project will also study the health of coral reef systems, ocean chemistry, and fisheries habitat. This team has developed a strategy to map the waters from nearshore to depths greater than 1000 meters. Within the project area, the ship's crew will collect bathymetric data to update charts and acquire backscatter data to characterized habitat, while visiting scientists from NCRMP will perform coral reef assessment dives and other oceanographic observations. Data collected during this mission are pivotal to long-term biological and oceanographic monitoring of coral reef ecosystems in American Samoa and PRIA. This project will add to information collected during previous monitoring and mapping surveys. Oceanographic and ecological time series data will allow scientists to evaluate potential changes in environmental conditions and coral reef health. This will enable federal and state resource managers to more effectively conserve coral reef ecosystems of American Samoa and PRIA, and manage ecosystem services. Data collected during this project also supports monitoring components of the NCRMP Coral Reef Ecosystem Integrated Observing System. A modern bathymetric survey in this area will identify hazards and changes to the seafloor, provide critical data for updating National Ocean Service (NOS) nautical charting products, and improve maritime safety. It will also address data gaps to support the Seabed 2030 global mapping initiative. Survey data from this project is intended to supersede all prior survey data in the common area. completed NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA National Centers for Environmental Information Water Column Sonar Data Manager (303) 497-4742 325 Broadway, Mail Code E/NE42 Boulder CO 80305-3328 USA wcd.info@noaa.gov pointOfContact notPlanned Earth Science > Oceans > Ocean Acoustics > Acoustic Scattering Earth Science > Oceans > Aquatic Sciences > Fisheries Earth Science > Oceans > Ocean Acoustics Earth Science > Biosphere > Ecosystems > Marine Ecosystems > Pelagic Earth Science > Biosphere > Ecosystems > Marine Ecosystems Earth Science > Biosphere > Ecosystems > Marine Ecosystems > Benthic Earth Science > Biosphere > Ecosystems > Aquatic Ecosystems Earth Science > Oceans > Bathymetry/Seafloor Topography > Bathymetry Earth Science > Oceans > Bathymetry/Seafloor Topography > Seafloor Topography theme Global Change Master Directory (GCMD) Science Keywords 2020-01-09 publication 9.1 NASA Goddard Space Flight Center, Earth Science Data and Information System https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

The EM 302 transducers are modular linear arrays in a Mills cross configuration with separate units for transmit and receive. This sonar offers significantly larger swath width, increased data density and resolution. Beam focusing is applied both during reception and transmission. The system has up to 288 beams / 432 soundings per swath with pointing angles automatically adjusted according to achievable coverage or operator defined limits. In multi-ping mode, 2 swaths are generated per ping cycle, with up to 864 soundings. With multi-ping the transmit fan is duplicated and transmitted with a small difference in along track tilt. The applied tilt takes into account depth, coverage and vessel speed to give a constant sounding separation along track. The beam spacing can be adjusted as equi-distant or equi-angular. EM 302 uses both CW pulses and FM sweep pulses with pulse compression on reception, in order to increase the maximum useful swath width. The transmit fan is split in several individual sectors with independent active steering according to accomplish compensation for the vessel movements: yaw, pitch and roll. The high density, high resolution, large coverage and water column capability makes EM 302 an ideal system to explore the sea bed and the water column for detection and characterization of a broad spectrum of features. RICHARD2023L4_EM304 completed NOAA Ship Rainier 2021-03-11 creation Rainier Homeported in Newport, Oregon, NOAA Ship Rainier is a hydrographic survey vessel that maps the ocean to aid maritime commerce, improve coastal resilience, and understand the marine environment. Rainier’s officers, technicians, and scientists log the data that NOAA cartographers use to create and update the nation’s nautical charts with ever-increasing data richness and precision.

The system is available in three separate configurations; one designed specifically for installation on small survey vessels and a 6000 meter depth rated system for either ROV or AUV use. Each of these configurations provides superlative data quality and ease of use over depths from 0.5 to 500 meters. Special emphasis has been put on maximizing operational efficiency and features such as variable swath width and roll stabilisation combined with a high ping rate and excellent data quality. The SeaBat 7125 provides a swath up to 165 degrees and uses up to 512 beams in operator selectable modes. Kongsberg EM710 Multibeam Echosounder EM710 Kongsberg Maritime http://www.km.kongsberg.com/ks/web/nokbg0240.nsf/AllWeb/993132242751F5EDC1256FA300360548?OpenDocument resourceProvider Kongsberg EM710 Multibeam Echosounder The EM 710 multibeam echosounder is a high to very high resolution (up to 800 soundings per ping) seabed mapping system capable of meeting all relevant survey standards. The system configuration can be tailored to the user's requirement, allowing for choice of beam widths as well as transmission modes. The minimum survey depth is from less than 3 meters below the transducers, and the maximum depth is approximately 2000 meters, somewhat dependant upon array size. Across track coverage (maximum swath width 140º) is up to 5.5 times water depth, to a maximum survey depth more than 2000 meters. The along track beamwidth depends upon the chosen transmit transducer configuration with 0.5º, 1º and 2º available as standard. The receive beam width is either 1º or 2º depending on the chosen receive transducer. The EM 710 operates at sonar frequencies in the 70 to 100 kHz range. The transmit fan is divided into three sectors to maximize range capability, but also to suppress interference from multiples of strong bottom echoes. The sectors are transmitted sequentially within each ping, and uses distinct frequencies or waveforms.
