As a result, different seamount science disciplines often do not collaborate or are not even aware of each other. However, it is obvious that interdisciplinary collaboration is the most successful approach to help understand the integrated chemical, phys- ical, and biological systems at seamounts.

  • Mapping Bathymetry
    Doctoral thesis in Marine Geoscience Meddelanden från Stockholms universitets institution för geologiska vetenskaper Nº 344 Mapping bathymetry From measurement to applications Benjamin Hell 2011 Department of Geological Sciences Stockholm University Stockholm Sweden A dissertation for the degree of Doctor of Philosophy in Natural Sciences Abstract Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. Examples, where knowing the exact water depth or the morphology of the seafloor is vital include marine geology, physical oceanography, the propagation of tsunamis and documenting marine habitats. Decisions made at administrative level based on bathymetric data include safety of maritime navigation, spatial planning along the coast, environmental protection and the exploration of the marine resources. This thesis covers different aspects of ocean mapping from the collec- tion of echo sounding data to the application of Digital Bathymetric Models (DBMs) in Quaternary marine geology and physical oceano- graphy. Methods related to DBM compilation are developed, namely a flexible handling and storage solution for heterogeneous sounding data and a method for the interpolation of such data onto a regular lattice. The use of bathymetric data is analyzed in detail for the Baltic Sea. With the wide range of applications found, the needs of the users are varying. However, most applications would benefit from better depth data than what is presently available. Based on glaciogenic landforms found in the Arctic Ocean seafloor morphology, a possible scenario for Quaternary Arctic Ocean glaciation is developed.

  • Arctic Ocean Bathymetry: a Necessary Geospatial Framework Martin Jakobsson,1 Larry Mayer2 and David Monahan2
    ARCTIC VOL. 68, SUPPL. 1 (2015) P. 41 – 47 http://dx.doi.org/10.14430/arctic4451 Arctic Ocean Bathymetry: A Necessary Geospatial Framework Martin Jakobsson,1 Larry Mayer2 and David Monahan2 (Received 26 May 2014; accepted in revised form 8 December 2014) ABSTRACT. Most ocean science relies on a geospatial infrastructure that is built from bathymetry data collected from ships underway, archived, and converted into maps and digital grids. Bathymetry, the depth of the seafloor, besides having vital importance to geology and navigation, is a fundamental element in studies of deep water circulation, tides, tsunami forecasting, upwelling, fishing resources, wave action, sediment transport, environmental change, and slope stability, as well as in site selection for platforms, cables, and pipelines, waste disposal, and mineral extraction. Recent developments in multibeam sonar mapping have so dramatically increased the resolution with which the seafloor can be portrayed that previous representations must be considered obsolete. Scientific conclusions based on sparse bathymetric information should be re-examined and refined. At this time only about 11% of the Arctic Ocean has been mapped with multibeam; the rest of its seafloor area is portrayed through mathematical interpolation using a very sparse depth-sounding database. In order for all Arctic marine activities to benefit fully from the improvement that multibeam provides, the entire Arctic Ocean must be multibeam-mapped, a task that can be accomplished only through international coordination and collaboration that includes the scientific community, naval institutions, and industry. Key words: bathymetry; Arctic Ocean; mapping; oceanography; tectonics RÉSUMÉ. Une grande partie de l’océanographie s’appuie sur l’infrastructure géospatiale établie à partir de données bathymétriques recueillies par des navires en route, données qui sont ensuite archivées et transformées en cartes et en grilles numériques.

  • Office of Coast Survey Contributions to a National Ocean Mapping Strategy
    Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy July 2020 Office of Coast Survey National Oceanic and Atmospheric Administration MESSAGE FROM THE DIRECTOR I am pleased to release this Office of the Coast Survey plan for contributions to a National Ocean Mapping Strategy. This timely report articulates our ongoing commitment and approach to meeting our core surveying and nautical charting mission while supporting broader societal needs to fill fundamental gaps in seafloor mapping. This is an exciting and pivotal time to be leading the nation’s primary marine mapping program. National and international interest has never been higher. Leaders are increasingly recognizing the value – indeed the necessity – of understanding the basic contours of the seafloor and marine environment to support the Blue Economy and successfully balance marine resource conservation and uses. This is clearly reflected in the June 2020 National Strategy for Mapping, Exploring, and Characterizing the United States Exclusive Economic Zone (EEZ).1 One of the most important goals in this Strategy is to map the U.S. EEZ, “larger than the combined land area of all 50 states, … containing 3.4 million square nautical miles of ocean.” With 54 percent of U.S. waters essentially unmapped, we have a great opportunity to conduct regional mapping campaigns, using a mix of survey techniques and technologies above, on and in the water. It is also important to make the resulting data usable and available in standard formats wherever possible. Adding emphasis to global interest in mapping the oceans, the United Nations has proclaimed a Decade of Ocean Science for Sustainable Development (2021-2030), calling for an increase in ocean research to support the sustainable management of marine resources and the Blue Economy.

  • Submarine Topography in the Gulf of Alaska
    BULLETIN OF THE GEOLOGICAL SOCIETY OF AMERICA VOL. 71, PP. 1087-1108. 12 FIGS.. 1 PL. JULY 1960 SUBMARINE TOPOGRAPHY IN THE GULF OF ALASKA By WILLIAM M. GIBSON ABSTRACT A bathymetric chart of the Gulf of Alaska and approaches covering an area of about 800,000 square nautical miles has been prepared from Coast and Geodetic Survey hydrography, 1925-1957, with a view to defining regional physiographic provinces. The basic data comprise 90 sounding lines across the gulf, 42,000 miles of graphically recorded profiles obtained during the last 5 years, and detailed surveys of 60 seamounts, seaknolls, and ridges. Tentative names are assigned principal features of the sea floor to facilitate discussion. The bathymetry and illustrated profiles reveal clearly the form of the Aleutian Trench, two submarine mountains, several seamount chains and groups, a ridge and trough prov- ince, a 200-mile trench west of Vancouver Island, a great trough paralleling the West Coast, and an inferred fracture zone extending in several wide echelon bands across the gulf. The submarine topography is discussed in relation to existing theories of earth science and correlated with features previously mapped on the mainland and in the Central Pacific Ocean.

  • Representations on Bathymetric Charts
    Internationa! Hydrographic Review, M onaco, LVIII (2), July 1981 REPRESENTATIONS ON BATHYMETRIC CHARTS by Bunkichi Imayoshi(I), Osamu A to b e (2), Masuoki H orikoshi (3), Kenzo Imai (2), Akira Irahara(4), Kokichi Ishii(2), Fusao Ito (2), Osamu N akamura (2), Kunikazu N ishizawa (2), Takahiro Sato (2), Hiroshi Shoj: (5) and Kunio Yashima (2) Paper presented at the 10th International Cartographic Association Conference, To­ kyo, August 1980. PREPARATION OF BATHYMETRIC CHART SERIES IN JAPAN The preparation of bathymetric charts in Japan started in 1925, when, on the occasion of the Third Pan Pacific Science Congress in Tokyo, Dr. O g u r a , a member of the Japanese Hydrographic Department, presented the first bathyme­ tric chart ever compiled in the country. The chart covered the seas adjacent to Japan and was based on sounding data collected up to 1 923 by the Hydrogra­ phic Department, for the purpose of producing nautical charts. For a long time the nautical chart was accepted as the sole map for the sea. In 1954 and 1955, a bathymetric survey for the submarine tunnel between Honshu and Hokkaido was carried out by the Hydrographic Department at the request of Japan National Railways. Since then it has been recognized that the bathy­ metric chart is an important basis of information for various ocean-related activities. In 1967, the Hydrographic Department commenced work on a project to pro­ duce “Basic Maps of the Sea” (scale 1:200 000) for the continental shelf margin.
