by more than 800 kilometers of fiber optic cable, NEPTUNE's research stations probe diverse underwater worlds extending from the
shallows of the
continental shelf into the depths of the abyss: 1.
Earlier this year an analysis of mitochondrial DNA conducted
by researchers in the United States, Japan, and Taiwan estimated that the first anglerfish appeared about 160 million years ago, during the Jurassic Period, and quickly diversified as they spread into habitats ranging from

The increased wave action reaches down and stirs up sediments on

by currents such as the Transpolar Drift.
The waves that run along
shallow continental shelves are much larger than those over the deep ocean, and so the force applied
by the standing waves is also larger in
shallow water.

shallow seas over
continental shelves that provided light, oxygen, and nutrients for life to thrive in, because intense mountain - building also increased erosion and the discharge of eroded nutrients into those seas.
