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 Information  
Project Title: Biogenic Calcium Carbonate Solubilities and Reaction Rates by Lab and Field Saturometry Project Status: Submitted
Principal Investigator: Adam Subhas, WHOI Project Institution: WHOI
Project ID: 106352 Version #: 2
Date Submitted: 2/11/2019 10:51:00 PM Created By: Adam Subhas
Date Last Modified: 8/3/2019 10:03:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/CO - 1923998 - Funded
Summary of Field Work: We will perform in situ ship wire experiments on the solubility and reaction kinetics of inorganic and biogenic calcium carbonates, including foraminifera, pteropods, and coccoliths. The study site is the Wilkinson Basin in the Gulf of Maine.

We will deploy two custom instruments which are battery powered. These instruments will be deployed on a non-conducting hydrowire at 200-250m depth for 10-24 hours at a time. A Seabird CTD will be deployed in between the two instruments. We will also potentially hang customized 1.2 L Niskin bottles above our instruments, which are triggered to close by traditional messengers. We will run at least five of these hydrowire-based experiments for a total cruise duration of 5-7 days.

Hydrocasts using a CTD/Rosette will be conducted before and after each experiment. If possible we would also like to deploy short-duration sediment traps.

We would like to catch the seasonally depressed aragonite saturation states in either the fall or spring of 2020. A regional-class ship should be of sufficient size to perform this work.
Summary of Facility Requirements: We will need a CTD/Rosette, a non-conducting hydrowire for experiment deployments (250m). Potentially an A-frame for deployment of sediment traps.

Requested Ship, Operating Days and Dates
Year: 2021 Ship/Facility: Endeavor
Optimum Start Date: 4/1/2021 Dates to Avoid: We need to catch the seasonal low in aragonite saturation in the Wilkinson Basin, which happens in the fall and spring. So either season will work, but winter and summer must be avoided.

Two custom-built, battery-powered instruments which will hang on a hydrowire at 250m depth. They will be about half the size and weight of McLane in situ pumps. Other devices will be custom-modified 1.2L niskin bottles which will hang on the same wire, spaced ~50m apart, to be triggered by traditional messengers.
