  2. Oceanic basin - Wikipedia

    en.wikipedia.org/wiki/Oceanic_basin

    Nevertheless, and since ocean basins are interconnected, many oceanographers prefer to refer to one single ocean basin instead of multiple ones. Older references (e.g., Littlehales 1930) [4] consider the oceanic basins to be the complement to the continents, with erosion dominating the latter, and the sediments so derived ending up in the ocean ...

  3. List of drainage basins by area - Wikipedia

    It includes drainage basins which do not flow to the ocean (endorheic basins). It includes oceanic sea drainage basins which have hydrologically coherent areas (oceanic seas are set by IHO convention). The oceans drain approximately 83% of the land in the world. The other 17% – an area larger than the basin of the Arctic Ocean – drains to ...

  4. Seabed - Wikipedia

    en.wikipedia.org/wiki/Seabed

    The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates mid-ocean ridges along the center line of major ocean basins, where the seabed is slightly shallower than the surrounding abyssal plain.

  5. Watersheds of North America - Wikipedia

    en.wikipedia.org/wiki/Watersheds_of_North_America

    The Pacific Basin is bounded by the Continental divide to the east and Pacific Ocean to the west; the basin excludes the endorheic Great Basin in the west. The Great Basin has a closed loop boundary encompassing substantially all of Nevada, the western half of Utah and parts of Oregon, California, Idaho, and Wyoming.

  6. Boundary current - Wikipedia

    en.wikipedia.org/wiki/Boundary_current

    The world's largest ocean gyres. Western boundary currents may themselves be divided into sub-tropical or low-latitude western boundary currents.Sub-tropical western boundary currents are warm, deep, narrow, and fast-flowing currents that form on the west side of ocean basins due to western intensification.

  7. Marine geophysics - Wikipedia

    en.wikipedia.org/wiki/Marine_geophysics

    Marine geophysics is the scientific discipline that employs methods of geophysics to study the world's ocean basins and continental margins, particularly the solid earth beneath the ocean. It shares objectives with marine geology , which uses sedimentological , paleontological , and geochemical methods.

    The NWS also said to expect ocean water to surge and sweep across beaches, coastal benches and lava flows, creating the potential for impacts to coastal properties and infrastructure, including ...

  9. Oceanic trench - Wikipedia

    en.wikipedia.org/wiki/Oceanic_trench

    Trenches were not clearly defined until the late 1940s and 1950s. The bathymetry of the ocean was poorly known prior to the Challenger expedition of 1872–1876, [12] which took 492 soundings of the deep ocean. [13] At station #225, the expedition discovered Challenger Deep, [14] now known to be the southern end of the Mariana Trench.
