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.

2005 Cruise
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.

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.
