The ocean twilight zone teems with life, from the microscopic to the gargantuan.

He adds: «This
twilight zone acts as a gate for the transfer of carbon to the deep
ocean.»
By using the manned submersible Curasub for exploration of the deep reefs around Curacao and documenting their discoveries in major scientific journals, marine biologists from all over the world have helped this Caribbean island in rapidly earning a reputation as a destination where exploring the
twilight zone of the
ocean is producing dynamic results.
The
twilight zone plays a prominent role in transferring the atmosphere's excess carbon dioxide (from fossil fuel burning) into deep
ocean storage.
In 2013, researchers with Britain's National Oceanography Centre explored the
twilight zone near Ireland from top to bottom, measuring carbon and
ocean life at all points.
The results also reveal that
twilight zone bacteria and zooplankton have a special synergy that plays a prominent role in how much carbon reaches the deep
ocean.

But the new study, detailed in the April 27 issue of the journal Science, finds that not all of this carbon makes it past the region of the
ocean known as the mesopelagic or «the
twilight zone» — roughly 300 to 3,000 feet below the surface where there isn't enough light for photosynthesis — which acts as a gateway to the deep
ocean below.
On its way to being stored in the darkest depths of the
ocean, carbon may be consumed and recycled by marine organisms as it enters... the
twilight zone.
«The
twilight zone is a critical link between the surface and the deep
ocean,» said Ken Buesseler of the Woods Hole Oceanographic Institute in Massachusetts, co-author of the new marine
twilight zone study.
The researchers found that only 20 percent of carbon in the
ocean surface made it past the
twilight zone off Hawaii, and only 50 percent passed through the gateway near Japan.
