Document/Research. Maximum depths from ETOPO1 are not expected to exactly match known measured maximum depths as ETOPO1 represents average depths over ~4 sq. (28) A bank covered 45 to 70 fathoms is 18 miles northwest of Tanner Bank. Mapsof depth-averaged temperature of the North Pacific Ocean are derivedusing the time series col-lected through 1998. In this zone, the intensity of light rapidly dissipates as depth decreases. Average depth is generally around 7,300 metres. This climatology is based on more than 100 years' worth of observations, and it incorporates a significant amount of data not previously available to the public. Sea-floor depths were corrected for sound velocity in sea water using Matthew's (1939) tables. The zone between 200 m (656 ft) and 1,000 m (3,280 ft) is usually referred to as the "twilight" zone, but is officially the dysphotic zone. Mesophotic reefs occur within the mesophotic (meaning "middle light") zone of tropical and subtropical ocean regions, ranging from 100 ft (~30 m) to over 490 ft (~150 m) depth. The North Pacific Gyre (NPG) or North Pacific Subtropical Gyre (NPSG), located in the northern Pacific Ocean, is one of the five major oceanic gyres.This gyre covers most of the northern Pacific Ocean.It is the largest ecosystem on Earth, located between the equator and 50° N latitude, and comprising 20 million square kilometers. 1, B and C).
