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: Nitrogen Fixation in Deep-sea Sediments Project Status: Submitted
Principal Investigator: Anne E. Dekas, Stanford Project Institution: Stanford
Project ID: 105156 Version #: 4
Date Submitted: 2/11/2016 6:23:00 PM Created By: Anne E. Dekas
Date Last Modified: 1/28/2017 4:36:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/BIO - 1634297 - Funded
Summary of Field Work: This work will characterize microbial activity related to nitrogen cycling in marine sediments during a single cruise. We plan to collect sediment cores using an 8-tube multicorer from the OSU Coring Facility at nine sites at a range of water depths (500 m to 4500 m). On-board, we will section the cores and preserve the sediment at a range of temperatures (4C, -20C, and -80C) for subsequent analyses. We will also set up bottle incubations with stable isotope labelled substrates (15N2 and 15NH4+). We would also like to collect water using a CTD rosette to characterize the biogeochemistry of the overlying water column.
Summary of Facility Requirements: We will need a CTD/rosette, 8-tube multicorer, sufficient deck space/A-frame/wire for multicorer deployments/recoveries, indoor bench space, refrigerator, freezers (-20 and -80), and space to secure a liquid nitrogen dewar.
Summary of other requirements and comments: The range of depths we want to sample is required -- 500 m to 4500 m -- but the exact location of the transect and the timing (time of year) is flexible.

CA Coast
Description of Op Area: We will collect samples along an approximately 145 nautical mile transect off the coast of California, just north of the Monterey Canyon. Our goal is to sample sediments from 500 to 4500 meters water depth down to 30-50 cm.

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
 Questions about ITAR/EAR regulations?

Port Calls
Requested Start Port Intermediate Port(s) Requested End Port
Moss Landing, CA, USA None, Moss Landing, CA, USA
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
We are requesting Moss Landing because it is the closest to our study site (174 nautical miles) and also to our home lab. The Monterey port is also close to the study site and would also be suitable.

Science Party
Chief Scientist: Anne E. Dekas, Stanford
# in Science Party 6 # of different science teams 1 # Marine Technicians to be
provided by ship operator:
(include in science party total)
Explanation of Science Party Requirements and Technician Requirements The science party will consist of six people: the PI, a postdoc, three graduate students and a staff scientist. This number of people will allow us to rapidly extrude and subsample the cores, allowing multiple multicore deployments per day, in addition to CTD sampling. Processing sediment immediately after collection is necessary for the microbiological work we will be doing. We also intend to set up an extensive set of bottle incubations on board (~600 100 ml bottles) which will require the full time attention of two of the scientists. The Oceanus requires one technician.
