Neutrally Buoyant Sediment Trap (NBST)

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.

2004 Cruise
June 20 July 11, 2004
This Web site was set up so we were able to post VERTIGO cruise updates from our June 20 – July 11, 2004 work on the University of Hawaii research vessel Kilo Moana and provide general information about our project. The site we went to north of the island of Oahu, is one of the most intensively studied pieces of ocean real estate. It is the location of the U.S. Hawaii Ocean Time-series (HOT) program where for the past 16 years marine scientists have been studying the ocean and the seasonal cycles of marine plants and animals, and how they impact the chemistry of the waters they live in.

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.
