@Sea - Drifting Houses in the Gulf Stream


HARBOR BRANCH research scientist Dr. Marsh Youngbluth and a team of international investigators will go to sea On 16 April, 2001, aboard the R/V SEWARD JOHNSON. The team will embark on a weeklong marine science cruise in the western Gulf Stream. The focus of the mission will be to document a little-known but ubiquitous and ecologically important class of pelagic tunicates called Appendicularians. A rigorous dive schedule is planned for the JOHNSON-SEA-LINK I (JSL I) research submersible, as the science team carries out the most ambitious series of in situ studies and live specimen collections yet attempted for these animals. Such cutting-edge science is possible due to the support of HBOI's experienced ship and submersible crews and a team of world-class ocean engineers.

@Sea will bring the action to you. Our board mission correspondent Dr. Jim Masterson will provide, via satellite, daily remote dispatches and digital imagery from aboard the R/V SEWARD JOHNSON. Check back each day during the mission to learn more about these under-appreciated animals that not only play a vital role in energy flow in shallow and deep marine ecosystems, but may also hold keys to unlocking the mystery of vertebrate evolution from our invertebrate ancestors. Share the excitement as marine scientists probe the waters off the Florida coast using high-tech gear, in hopes of capturing and studying the strange and fragile Appendicularia.

This expedition is made possible through a grant from the Biological Oceanography Program of the National Science Foundation with additional support from Harbor Branch Oceanographic Institution.
