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: Collaborative Research: ETBC: Amazon iNfluence on the Atlantic: CarbOn export from Nitrogen fixation by DiAtom Symbioses (ANACONDAS) Project Status: Submitted
Principal Investigator: Patricia L. Yager, Georgia Project Institution: Georgia
Project ID: 103110 Version #: 1
Date Submitted: 8/30/2011 5:04:00 PM Created By: Patricia L. Yager

Funding Agencies: NSF/OCE/BIO - 0934095 - Funded

Summary of Field Work: We request one two-week (15 day) research expedition to the nearshore Amazon River plume (0-10N, 45-55W) during late-spring/early summer (May-June). Our preferred port of call would be Barbados. This additional cruise (beyond the two already funded) would allow us to sample the critical inner plume area during the flood stage of the river. Our funded research cruise in May 2010 was not able to sample this area as expected because there was an embassy error in obtaining our coastal permissions from Brazil. We did not discover the error until we were at sea (and compared files with the Brazilan Navy observer onboard). At that point it was too late to fix.

This additional cruise would allow us to survey waters in and around the inner Amazon plume and near the mouth to characterize the diversity and activity of N2-fixing organisms and their impact on C and N export to the deep sea. We will collect water samples for analysis and experimentation using a CTD/rosette and will carry out an extensive suite of experiments to measure the rates of N2-fixation and primary and secondary production in these waters. We will collect zooplankton with a mocness system and bottom samples with a multicorer.
Summary of Facility Requirements: We request principle use of a large (global-class) ship capable of deploying a CTD/rosette to 1000 m, a multicorer off the fantail with a winch to 5000 m, vertical and diagonal zooplankton nets, and floating sediment traps to 200 m. We will also need a cold van and a radiation safety van onboard. We need to image the seafloor using 12KHz or better sonar system. Support for ~30 scientists onboard. We need a CTD/rosette, a meter mocness system, a hydrowire for deploying nets, a multicorer, and provision for deploying hand nets from the fantail. We also need deck space for flowing seawater incubators and lab space for filtrations, nutrient chemistry, microscopy, core-processing and other lab analyses.
Summary of other requirements and comments: Results from our May-June 2010 expedition onboard RV Knorr confirmed that the outer plume is a strong sink for CO2. Intermediate salinity stations (mid-plume) show a net balance between autotrophy and heterotropy (CO2-neutral), but the inner plume (for which we only have one station at 16 ppt) suggests that the plume flips back to net-autotrophic (CO2 sink). Since the inner plume covers a large area - having no data from that area makes modeling and whole-ecosystem calculations of the CO2 impact and nutrient budgets difficult. If approved, we would start the Brazil permissions process immediately. We are currently on the verge of getting those permissions for our Melville expedition in September. I will let you know as soon as I know we have them.

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
We need a global class vessel to accomplish the various operations over abyssal depths, particularly the coring. Our timing choices reflect that we are trying to capture the maximum flood stage of the river, which occurs during May or June each year.

Foreign Clearance and Permitting Requirements
Foreign Clearance Required? Yes Coastal States:

Brazil, Barbados, Guyana, Suriname
 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
Bridgetown, Barbados Bridgetown, Barbados Bridgetown, Barbados
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
Barbados has easy airport access from US, shipping is relatively easy, liquid nitrogen is available. Intermediate port-of-call would be used for swapping science personnel, shipping home time-sensitive or storage-sensitive samples, refreshing perishable supplies like liquid N2 or dry ice stores.
