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: North Atlantic Meridional Circulation during the Last Glacial Maximum: Density Structure and Pre-formed Nitrate Project Status: Submitted
Principal Investigator: Arthur Spivack, URI_GSO Project Institution: URI_GSO
Project ID: 103830 Version #: 1
Date Submitted: 2/15/2013 4:39:00 PM Created By: Robert A. Pockalny
Date Last Modified: 5/15/2014 9:36:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1334606 - Funded
Summary of Field Work: This project will involve sediment cores at 7 sites in the western North Atlantic (Researcher Ridge and Nares Abyssal Plain) at water depths ranging from 1000 to 6000 m. Coring sites will be identified with multibeam swath mapping and CHIRP sub-bottom seismic data. Coring operations will include the WHOI Long Core, gravity cores, multi-cores and hydrocasts with a CTD/Niskin Bottle Rosette. Optimal cruise times are January to April, due to tropical cyclone activity in our operations area during the months of June through October.
Summary of Facility Requirements: Geophysical Site Survey:
- Deep-water multibeam bathymetry and backscatter
- CHIRP Sonar

Coring Operations:
- WHOI Long Core & shipboard support personnel
- Gravity Cores
- Multi-Core
- CTD/Rosette
- Geobiology Field Lab
- Refrigerated core container provided by WHOI Long Coring facility
Summary of other requirements and comments: Lab space for core description, sampling and analysis.
Standard core supplies (e.g., core liners, storage tubes, end caps for core liners and storage tubes, core cutters, etc).
Standard sediment description instruments (microscope, etc.)
Two -80° freezers

Requested Ship, Operating Days and Dates

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
Ship Choice:
- Only the R/V Knorr can accommodate the WHOI Long Core operations.

- January through April is the best weather window to avoid tropical storm activity in our proposed operation areas.

Number of Days:
Transit times to/from our first/last coring sites is estimated at 4 days each way (total 8 days) for transit speeds of 10 kts.
We calculated occupying each coring station for 2 days for initial survey and full suite of coring operations (gravity, 2 long cores, hydrocast, multi-core). For 7 sites that is 14 days.
We estimate a cumulative 8 days of transit time between successive coring sites.
Our experience with the Long Core system also sugegsts we will need a full day before and after the cruise to load and offload our science gear, supplies and cores.
The mob/demob times may be reduced if equipment can be loaded and/or unloaded at WHOI.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? No Coastal States:
 Important Info on Foreign Research Clearances  

Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
No If yes, have you applied for the necessary permits through your export control office? No

Port Calls
Requested Start Port Intermediate Port(s) Requested End Port
San Juan, Puerto Rico None Woods Hole, MA, USA
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
San Juan, Puerto Rico is a closest major port to our first coring site and will be able to handle the required vans and materials for use on the cruise. Woods Hole is the home port to the R/V Knorr and is close to URI/GSO where the cores will be stored.
