2015 with maximum SST anomalies of 6C off Southern California Jacox et al 2016 69. Many feed on the abundant plankton.

The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean.

. They occupy the sea floors and lake beds which usually consist of mud sand gravel or rocks. Gentemann et al 2017 70. Demersal fish also known as groundfish live and feed on or near the bottom of seas or lakes the demersal zone.

The benthic zone is the area below the pelagic zone but does not include the very deepest parts of the ocean see abyssal zone below. Largest heatwave ever recorded often called The Blob. The mesopelagic zone is the disphotic zone meaning light there is minimal but still measurable.

Rudnick et al 2017 71 and subsurface warm anomalies in the deep British Columbia Fjord that persisted through the beginning of. However characteristics of deep-sea organisms such as bioluminescence can be seen in the mesopelagic 2001000m deep zone as well. In coastal waters they are found on or near the continental shelf and in deep waters they are found on or near the continental slope or along the continental rise.

Here temperature decreases as depth increases toward the abyssal zone since light cannot penetrate through the deeper water. The bottom of the zone consists of sand slit andor dead organisms.
