Major marine life/habitats: plankton - live suspended in water, non-swimming or weakly swimming, cannot counteract currents, turbulence, bacteria, protists, plants, animals < few cm, nekton - larger animals able to swim against current, turbulence, shrimp to whales. Includes seabirds, pinnipeds etc: neuston - sea surface organisms, bacteria to flying fish, benthos - seafloor-dwelling, benthos types. In open ocean, salinity 33-37 psu: highest around 30on and s, lowest near 0o and poles, marginal seas may be much more or less saline, dissolved oxygen, atmospheric o2 dissolved into seawater at surface. If organic matter accumulates in thermocline (where temperature changes greatly), o2 depletion occurs: can result in mass fish mortality, light penetration, the vast majority of light energy is from the sun, pe(cid:374)etrates the (cid:449)ater"s surfa(cid:272)e fro(cid:373) a(cid:271)o(cid:448)e.
