Ship Request

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: Hydrothermal Exploration in the Mariana Back-arc: Understanding the physical, chemical, and geological forces that shape biodiversity Project Status: Submitted
Principal Investigator: Joseph Resing, UW Project Institution: OSU_HMSC
Project ID: 104133 Version #: 2
Date Submitted: 11/12/2013 3:07:00 PM Created By: William W. Chadwick
Date Last Modified: 2/13/2014 11:36:00 AM URI Serial #: None
Funding Agencies: OTHER - NONE - Funded
NOAA/OE - NONE - Pending
Summary of Field Work: This project consists of two legs on R/V Falkor in Nov-Dec 2015, each using the port of Guam. Leg 1 will use a CTD and AUV Sentry to survey systematically for hydrothermal plumes along the Mariana back-arc between 13°N and 18.5°N. This Leg will identify and map new vent sites. Leg 2 will then make dives with the Nereus ROV to visually explore the newly discovered vents and sample their fluid chemistry and biology.
Summary of Facility Requirements: Leg 1 (21 days) requires the Sentry AUV. Leg 2 (22 days) requires Nereus in ROV mode. We have chosen Sentry for use on Leg 1 because it is the most efficient AUV for this purpose (including dive duration and survey speed), and Nereus is required for Leg 2 because it is the only ROV currently capable of making dives deeper than 3000 m from R/V Falkor.
Summary of other requirements and comments: The latest update from Eric King of Schmidt Ocean Institute is that these cruise legs are likely to be scheduled in Nov-Dec 2015.
