VERtical Transport
In the
Global Ocean-
aka VERTIGO-
is currently one of our largest and most exciting projects.
As its name implies, this study looks at how materials get
from the surface to the deep ocean. In fact, there are really
only two ways to get there—either with ocean currents that
sink to the deep ocean, but that takes place only in a few
regions near the Arctic and Antarctic, or hitching a ride
on sinking particles, and it’s the sinking particle
story that VERTIGO is all about.
- Where do marine particles come from?
- How do marine plants and
animals create and destroy particles in the ocean?
- How quickly
do particles sink? How deep do they go?
- Are all marine particles
the same?
- And what is the marine “snow” forecast?
Many basic questions such as these will be addressed by this
international, interdisciplinary team of ocean scientists.

July 21 - August 27, 2005
VERTIGO scientists are heading to cold and nutrient rich
waters in the NW Pacific on the R/V
Revelle in search of a region where particle fluxes out
of the surface ocean are thought to be among the world's highest.
A site called "K2" has been chosen for our second major research
expedition, since this is where the Japanese already maintain
deep ocean sediment traps which capture sinking particles below
the "twilight zone" where VERTIGO scientists will be working.
At "K2" the High
Latitude Time
Series (HILATS)
Observatory program has been in place only since 2001.

Sponsors
VERTIGO has been supported primarily by the U.S. National Science
Foundation in collaboration with the Antarctic Climate &
Ecosystems Cooperative Research Centre, the U.S. Department
of Energy, Woods Hole Oceanographic Institution and the Fund
for Scientific Research - Flanders (Belgium) and other national
and international sponsors.
