2024 R/V Thompson Transit

Float deployments on the R/V Thompson transit from Honolulu, Hawaiʻi to Apra Harbor, Guam.

A true cruise of opportunity, GO-BGC will deploy six WHOI floats from the R/V Thompson as the ship transits from Hawaiʻi to Guam. The ship is headed to Guam to pick up another scientific party, but on this transit, there is no other science purpose except float deployment and concurrent water sampling. Cora Hersh, a graduate student in the MIT-WHOI Joint Program, will be on the transit cruise in charge of deployment and sampling for the six floats on board.


Chief Scientist: Deborah West-Mack, Woods Hole Oceanographic Institution
