EQUIPMENT Detailed descriptions of the equipment and systems, including hardware and software, used for bathymetric data acquisition and processing are listed below. 1.0 Hardware 1.1 Hardware Systems Inventory Detailed hardware information, including models and serial numbers, is included in Appendix I of this report. All launch hardware was verified during the months of February and March 2014. Manufacturer’s product specifications are maintained with reference documentation on board Fairweather. 1.2 Echo Sounding Equipment 1.2.1 Reson 7125 SV Multibeam Echosounder (MBES) Survey launches 2805, 2806, 2807, and 2808 are each equipped with a dual frequency Reson 7125 SV MBES. The Reson 7125 SV has both a low frequency (200kHz) and high frequency (400kHz) transmit array with swath coverage of 128°. The swath is made up of 256 discrete beams for 200 kHz and either 256 or 512 discrete beams for 400 kHz. The typical operational depth ranges for the Reson 7125 SV operating at 200 kHz is 3 to 400 meters and 3 to 100 meters operating with the 400 kHz system.

Energy and material are continually exchanged at the interfaces between water and air, ice, rocks, and sediments. In addition to the physical and chemical processes, biological processes play a significant role. Vast areas of the ocean remain unexplored. Investigation of the surface ocean is carried out by satellites. All other observations and measurements have to be carried out in-situ using research vessels and spe- cial instruments. Ocean observation requires the use of special technologies such as remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), towed camera systems etc. Seismic methods provide the foundation for mapping the bottom topography and sedimentary structures. We cordially welcome you to the international OCEANS ’09 conference and exhibition, to the world’s leading conference and exhibition in ocean science, engineering, technology and management. OCEANS conferences have become one of the largest professional meetings and expositions devoted to ocean sciences, technology, policy, engineering and education.

  • Descriptive Report to Accompany Hydrographic Survey H-10791
    U.S. DEPARTMENT OF COMMERCE NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION NATIONAL OCEAN SERVICE Data Acquisition & Processing Report Type of Survey Hydrographic Project No. 2011 Rainier field season Time frame June - October 2011 LOCALITY State Washington/Alaska General Locality Strait of Georgia, WA and West of Prince of Wales Island, AK 2011 CHIEF OF PARTY Captain Donald W. Haines, NOAA LIBRARY & ARCHIVES DATE Data Acquisition and Processing Report NOAA Ship Rainier (s221) 2011 Field Season Chief of Party: Captain Donald W. Haines, NOAA A. EQUIPMENT This Data Acquisition and Processing Report describes both the survey equipment used and the standard methods for acquisition applied to the equipment used. Not necessarily all equipment described within this report was used during data acquisition for all projects and/or sheets. Data were acquired by the following Rainier survey vessels: Hull Number Vessel type 2801 28 foot Jensen survey launch 2802 28 foot Jensen survey launch 2803 28 foot Jensen survey launch 2804 28 foot Jensen survey launch S221 231 foot steel hydrographic ship Vessels S221, 2801, 2802, 2803, and 2804 are used to acquire shallow-water multibeam (SWMB) data and sound velocity profiles. Any vessel may be utilized for collecting bottom samples and detached positions (DPs). Vessel descriptions and offset measurements are included in the 2011 NOAA Ship Rainier Hydrographic Readiness Review Package. Three different categories of echosounder systems are available for use by Rainier survey vessels. The individual system(s) chosen for use in a given area were decided at the discretion of the Hydrographer using the guidance stated in the Hydrographic Survey Project Instructions, the Hydrographic Surveys Specifications and Deliverables Manual (HSSDM), and the Field Procedures Manual, and depended upon the limitations of each system, the bottom topography, the water depth, and the ability of the platform vessel to safely navigate the area.

    I. OVERVIEW A. Brief Summary and Project Period From April to July 2016, NOAA and partners will conduct three telepresence-enabled ocean exploration cruises on NOAA Ship Okeanos Explorer to collect critical baseline information in and around the Commonwealth of the Northern Marianas Islands (CNMI) and the Marianas Trench Marine National Monument (MTMNM). NOAA will work with the scientific and management community to characterize unknown and poorly-known areas through telepresence-based exploration. This expedition is part of a three year Campaign (CAPSTONE) focused on systematically collecting baseline information to support science and management needs within and around the Monuments and other protected places in the Pacific, and serves as an opportunity for NOAA and the Nation to highlight the uniqueness and importance of these national symbols of ocean conservation. This document contains project instructions for EX-16-05 Leg 1. Operations for this cruise will include ROV, mapping, telepresence-based remote participation, and CTD rosette operations. The expedition will be commence in Santa Rita, Guam with operations beginning on April 20th and conclude in Saipan, CNMI on May 11th. Operations will use the ship’s deep water mapping systems (Kongsberg EM302 multibeam sonar, EK60 split-beam fisheries sonars, ADCPs, and Knudsen 3260 chirp sub-bottom profiler sonar), NOAA’s two-body 6000 m remotely operated vehicle (ROVs Deep Discoverer and Seirios), CTD rosette, and the ship’s high-bandwidth satellite connection for real-time ship to shore communications. Daytime ROV dives are planned every day from April 21 –May 10. ROV dives will include high-resolution visual surveys and limited rock and biologic specimen sampling.

These subsurface features affect bridge scour, flood mitigation, erosion control and siltation transport, maritime navigation, marine construction, dredging, offshore oil exploration and offshore oil drilling, among many other activities. Hydrographic surveying does not strictly apply to coastal and oceanic regions of the US. Hydrographic surveying has many applications inland. Many environmental and civil engineering project in and around bodies and channels of water (streams and rivers, lakes and ponds, wetlands) can all benefit from hydrographic surveys and analysis.

Canadian Forces (CF) personnel are required to make assessments of the effects of meteorological, oceanographic, and/or ice conditions (hereafter referred to as “Met Effects”), on the operation of CF equipment. The current methods of assessing Met Effects for the CF rely on a suite of standard NATO criteria and manual or semi-automated processes. More sophisticated systems exist that offer improved estimates through automated software applications. One such system, Navy Integrated Tactical Environmental System, Variant II Redesign (NITES IIR or N2R), is a sophisticated Met Effects assessment application with performance degradation predictions for known capabilities. For each specific piece of equipment, the N2R application forms an assessment based on certain aspects of the equipment's operating characteristics and technical specifications and how they react to varying meteorological, oceanographic, or ice conditions.

  • Underwater Inspection of Bridge Substructures Using Imaging Technology
    Underwater Inspection of Bridge Substructures Using Imaging Technology June 14, 2018 Sponsored by Federal Highway Administration Office of Infrastructure FHWA-HIF-18-049 FOREWORD With the growth in the range and capabilities of sonar technology, many states are investigating its use for underwater bridge substructure inspection. FHWA provides overall guidance for these inspections and recognized the need for a comprehensive evaluation of the capabilities of sonar technologies for this important activity. In this study, a range of sonar technologies were evaluated in a variety of underwater conditions to evaluate how these technologies can be effectively used in conjunction with or independently of divers. It will be useful for bridge personnel responsible for inspecting bridge foundations. The study described in this report was conducted at the Federal Highway Administration (FHWA) Turner-Fairbank Highway Research Center (TFHRC) J. Sterling Jones Hydraulics Laboratory. The state transportation departments that contributed funding for this study were California, Missouri, North Dakota, South Carolina, Texas, and Wisconsin.
