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: Mechanisms of nutrient input at the shelf margin supporting persistent winter phytoplankton blooms downstream of the Charleston Bump Project Status: Submitted
Principal Investigator: James Nelson, Skidaway Project Institution: Skidaway
Project ID: 102544 Version #: 1
Date Submitted: 6/10/2010 3:30:00 PM Created By: James Nelson
Date Last Modified: 7/14/2010 1:40:00 PM URI Serial #: None
Funding Agencies: NSF/OCE/BIO - 1032285 - Funded
Summary of Field Work: This collaborative project with Harvey Seim (University of North Carolina, Chapel Hill) and Catherine Edwards (SkIO) investigates physical-biological coupling on the outer continental shelf/upper slope of the South Atlantic Bight (SAB) inshore of the zone of maximum deflection of the Gulf Stream (off Long Bay). The field work focuses on physical mechanisms of nutrient input from the upper slope to the outer shelf euphotic zone in winter, the new primary production this supports, and functional characteristics of the phytoplankton bloom assemblage.

The observational approach will utilize two autonomous Teledyne Webb Slocum gliders, three moored instrument packages on the outer shelf, shelf break and upper slope (at ~30, 75 and 150 m depth), and intensive ship surveys. The shelf break mooring will include an autonomous moored profiler (ODIM Brooke Ocean SeaHorse). The ship survey work will employ a towed, undulating multi-instrument package (Sea Sciences Acrobat) for repeated surveys of the bloom features on the outer shelf off Long Bay (~40 km cross-shelf x 80 km along-shelf). Surveys will alternate with CTD/carousel stations that will include sampling for pigments, nutrients, primary productivity experiments, and analyses of the functional characteristics of the phytoplankton assemblage. The microplankton will be characterized by shipboard analyses of live samples using a microfluidics/imaging system (Fluid Technologies, Inc. "Flow-Cam"), augmented by lab work with preserved samples. 14C-HCO3 uptake experiments will be conducted using a deck incubator system and photosynthetron units. Isotope work (label additions and sample processing) will be conducted in the ship's isotope van. Given the frequency of winter storms, our field strategy using this coastal class vessel will be to shelter in Winyah Bay or in the lee of Cape Fear during storms to be in position for rapid response to favorable workable conditions (seas of ~1.8 m or less for the Acrobat surveys).

Year 1 field work will involve a 1-month deployment of the gliders, and several field trials for a reconfigured Acrobat package, the autonomous moored profiler (SeaHorse) and field trials of the Flow-Cam system (to establish protocols for intensive work in Year 2).

The major field effort in Year 2 will be conducted between Jan-April, 2012. An initial cruise (5-d from SkIO) will deploy the moorings, and test and deploy the glider. This will be followed by three 12-d cruises spaced between Feb and the beginning of April for intensive surveys and sampling of the bloom features. Due to repeated winter storms, we will operate from Long Bay during these periods, working on the outer shelf between storms and sheltering in Winyah Bay, SC or in the lee of Cape Fear, NC during storms. In addition to the SkIO/UNC-CH scientific party, most cruises will also include two experienced observers who will be conducting surveys of seabirds and cetaceans (part of our community outreach effort). In mid-April, a 5-d cruise will be conducted to recover the glider and moored packages. A follow-up cruise in 2013 will target along-shelf sampling of bloom features detected in satellite imagery.
Summary of Facility Requirements: All cruises will utilize the R/V Savannah's CTD/carousel and along-track mapping system.

Deck incubators will be designed and constructed at SkIO and secured near the aft-starboard rail for cruises.

Three intensive survey/sampling cruises will require use of the ship's isotope van (positioned on the port side of the fan tail area).

A small winch with faired cable (SkIO inventory) will be mounted on the deck for the Acrobat package.

Operations will use both A-frame and J-frame.

The ship's wet lab will be used for sample processing and storage in refrigerator and freezer, and a large liquid N2 Dewar will be carried for pigment samples (SkIO inventory). The dry lab benches will be used for laptops for Acrobat control, communications with the glider and for the Flow-Cam system.

We anticipate use of the ship's sat comm system for obtaining regular updates of satellite imagery for the study area.

Scientific parties (SkIO, UNC-CH) would be 5-8 personnel per cruise plus 1-3 observers for the seabird survey component, and 1-2 students from Georgia Tech Savannah campus.

The ship's tender (RHIB) will likely be used when inshore in Winyah Bay for exchange of seabird observers.
Summary of other requirements and comments: NOTE:

This STR is to replace an earlier submission.

The STR submitted in February 2010 showed up as submitted on the "Principal Investigator" page (with UNOLS Project ID #102415), but does not appear on the "Scheduling" page for the R/V Savannah. In the original submission, I had duplicated an earlier submission and then edited dates of cruises. Dates for "earliest start" and "latest start" appear to have not been edited, resulting in those being for the prior year (e.g., requested start dates in 2011, "earliest" & "latest" in 2010).

Possibly this error resulted in the request showing as "submitted" on the PI page not being accepted by the "Schedule" part of the system.
