The next dive ( dive 64 in a series, seventh in the Nekton series ) reached 24, 000 feet in the Nero Deep in the Mariana Trench 70 miles off Guam.

For instance, the Nekton Pilot is a live-aboard dive ship that sails out of Fort Lauderdale, Fla ., taking 30 passengers to scuba dive and snorkel in remote Caribbean areas.

Starting in November 1959 she took part in Operation Nekton, a series of deep dives in the Mariana Trench by Trieste, a deep-diving research bathyscaphe purchased by the Navy the previous year.

The Navy might use schools of these robotic micro-subs, which can communicate with each other, to find downed planes on the sea floor, said Chuck Pell, Nekton's technology director.

Nekton, on the other hand, are larger and swim at biologically high Reynolds numbers ( 10 3 to 10 9 ), where inertial flows are the rule and eddies ( vortices ) are easily shed.

Contrast the terms plankton ( the organisms that float or drift within the water ), nekton ( the organisms that swim ( powerfully ) in the water ), and neuston ( the organisms that float on the water ).
27.
Bioaccumulation and bioconcentration result in buildup in the adipose tissue of successive trophic levels : zooplankton, small nekton, larger fish, etc . Anything which eats these fish also consumes the higher level of mercury the fish have accumulated.
28.
Many organisms, such as jellyfish and most fish, start life as larva and other tiny members of the plankton community, swimming at low Reynolds numbers, but become nekton as they grow large enough to swim at high Reynolds numbers.

On 5 October 1959, " Trieste " departed San Diego for Guam aboard the freighter " Santa Maria " to participate in " Project Nekton ", a series of very deep dives in the Mariana Trench.

Contrast the terms plankton ( the organisms that float or drift within the water ), nekton ( the organisms that swim, powerfully, in the water ), and benthos ( the organisms on the bottom of a body of water ).
