STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning ( Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

Project Title: Chemical ecology of sponges on Caribbean reefs Project Status: Submitted
Principal Investigator: Joseph R. Pawlik, UNC_W Project Institution: UNC_W
Project ID: 102334 Version #: 1
Date Submitted: 2/3/2010 3:22:00 PM Created By: Joseph R. Pawlik

Funding Agencies: NSF/OCE/BIO - 1029515 - Funded
Summary of Field Work: This renewal will test the ecosystem model of sponges on Caribbean reefs with three primary objectives. The first is to extend our investigations of top-down control of the sponge community. Using the World Resources Institute “Reefs at Risk” database as a guide, we will predict and compare the community structure of sponges and sponge predators on overfished vs. heavily protected reefs. The under-recognized importance of parrotfish predation on sponges will be studied using video-monitoring experiments. Allelopathic competitive interactions between sponges and corals will continue to be investigated using a modified gel-based field assay and diving-PAM fluorometry to determine the differential effects of sponge metabolites on coral photosynthesis and bleaching. The second objective is to better test a competing hypothesis that bottom-up processes, specifically the availability of picoplankton as food, control reef sponge communities. Predator-exclusion experiments will be conducted that decouple the effects of predation from sponge growth at picoplankton-rich and poor, deep and shallow reef sites. The third objective is to expand investigations of sponge life history trade-offs in resource allocation between chemical defense, growth and reproduction by examining differences in recruitment and succession among sponge communities of known age on the surfaces of artificial reefs. This component builds on our recent discovery of sponge community succession on the deck surface of the 155m long shipwreck Spiegel Grove off Key Largo, Florida, the sequence of which strongly corroborates a resource trade-off between chemical defenses and reproduction or growth.
Summary of Facility Requirements: Access to pristine reef sites in the Caribbean, particularly the Bahamas Islands, with appropriate permits for manipulative experiments and limited collections. Berths and dry lab space for 12 scientists. Wet lab space. 3 small boats, 4-5 boat engines, diving compressor.
