Global seafloor topography (predicted bathymetry) NOTB EUS

deep sea, seamounts provide raised and exposed habi-tat where hydrodynamic energy can be focused and secondary biological productivity may be enhanced (McClain 2007). Seamounts (as defined by Pitcher et al. 2007) are elevated seafloor structures, mostly formed by volcanism (Wessel 2007), that are numerous (e.g. >30000 in the Pacific Ocean, Smith & Jordan 1988), but mostly small in area (e.g...

You’ll notice when you study the Ocean Tracks bathymetry map that there is a chain of seamounts extending north from the Hawaiian Islands (see image below). This chain of undersea mountains is important evidence of plate tectonics. Hawaii is above a volcanic hot spot in Earth’s mantle, and as the Pacific Plate has moved in a northwesterly direction over millions of years, the volcanic

  • sphere is the Hawaiian-Emperor seamount chain in the Pacific Ocean. The earliest gravity measurements [gening Meinesz, 1941] suggested that the load of the seamount chain was not supported according to the Airy model of isostasy but was regionally supported. Gunn [1943], Walcott [1970a], and Watts and Cochran [1974] have shown that gravity data are generally consistent with a …
