Seafloor Crust


seafloor crust
    seafloor
  • The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean. At the bottom of the continental slope is the continental rise, which is caused by sediment cascading down the continental slope.
  • The bottom of a sea or ocean; often covered with sediment
  • the solid surface underlying a body of water; also called seabed.
    crust
  • A slice of bread from the end of the loaf
  • the outer layer of the Earth
  • form a crust or form into a crust; "The bread crusted in the oven"
  • a hard outer layer that covers something
  • The tough outer part of a loaf of bread
  • A hard, dry scrap of bread

Mantle and Lower Crust Exposed in Oceanic Ridges and in Ophiolites: Contributions to a Specialized Symposium of the VII EUG Meeting, Strasbourg, Spring 1993 (Petrology and Structural Geology)
The processes involved in accretion taking place at oceanic ridges are approached here via petrological and structural analysis of oceanic rocks in present-day oceanic ridges, combined with similar studies based on ophiolites, and includes present cases of slow and fast oceanic spreading and inferred analogues in ophiolites. A complementary model study of cyclic oceanic activity reconciles the extreme cases of slowly and rapidly spreading ridges. In essence, based as it is on the analysis of `real rocks', this book on mantle-crust interactions reinforces the well-known contrast between processes taking place at slow and fast oceanic ridges. Audience: Contains valuable information for scientists interested in the nature and generation of the ocean floor in present-day oceanic ridges and in their ophiolite counterparts.

Project TOPAZ
Project TOPAZ
This endeavor aims to vertically drill towards the center of the Earth to cause artificial volcanic eruptions and/or earthquakes. The energy released by these events is considerable. Note that the energy in Joules equals 1.74 x 10(5 + 1.44*M) with M being the Richter magnitude. The deepest hole ever drilled by the Integrated Ocean Drilling Program was to 4.943 feet below the sea-floor in the Pacific Ocean off Costa Rica. IODP’s predecessor, the Ocean Drilling Program, reached 6.924 feet into the seafloor, also in the eastern Pacific Ocean. We will obviously focus our attention to American territory, where the crust of the Earth is comparatively thin so there will be significant yield of material. (The gained volcanic material, expected to be mostly iron, might be used in conjunction with project SUNSTONE) Should the generation of seismic activity prove to be successful, the collection of energy is likely to happen through hollow containers with variable volume which can be adapted to the eigenfrequency of the quake-event. The violent reverberations of the space are caught by a multitude of generators.

View of LAKE TEKAPO from the top of Mount John. Lake Tekapo township is on the right (see close-up view posted in comments). Tekapo in Maori means night sleeping place. Lake Tekapo has the clearest and darkest night sky in New Zealand. Millions of years ago, this area was part of a seafloor valley. Movement of two large plates of the earth's crust had pushed the seabed upwards to form the land it is today. During the ice-age era, huge glaciers of ice deposited large volumes of rock at its terminal, forming a dam that trapped the glacial water in the valley. This glacial lake covers an area of 83 square kms, and is at an altitude of 710 metres above sea level (making it the highest lake in New Zealand). Maximum length is 27 kms, maximum width is 6 kms, maximum depth is 120 metres. Lake Tekapo, Mount John University Observatory, South Island, New Zealand (Monday 2 May 2011 @ 3:17pm).
