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: Toward Improving Coastal Fog Prediction (C-FOG) Project Status: Submitted
Principal Investigator: Harindra J. Fernando, ND Project Institution: ND
Project ID: 106146 Version #: 2

Summary of Field Work: This project concerns a two-year comprehensive research program on coastal fog with emphasis on understanding and parameterizing sub-grid thermodynamic and microphysical processes relevant to improving numerical weather prediction and other forecasting models.

The project is centered on a field program over land and water to be conducted during September to November 2018. The land program will be based on two specific sites: St. John’s/Bay Bulls (Newfoundland) and Ovens Natural Park/Lunenberg (Nova Scotia), Canada, the former being known as the fog capital of the world. The two sites will be densely instrumented with flux towers (momentum, temperature and moisture), lidar systems, microwave radiometers, aerosol particle counters, scintillometers, sodars/RASS and ceilometers. A DIAL lidar is being pursued for water vapor measurements.

The ocean based measurements are scheduled during 1-30 September 2018. During this period, the climatology of the area is rich in fog and no-fog days, thus allowing to observe dynamicl ocean-atmosphere conditions for fog formation and dissolution as well as delineate mechanisms underlying the life cycle of coastal fog.

It is hypothesized that the temperature gradients between Gulf Stream and Labrador Current waters create favorable conditions for fog formation and advection toward the coast. Horizontal mixing between the two currents, small-scale vertical mixing processes, sea surface temperature, air-sea fluxes and near-surface density stratification are considered as factors that lead to local fog generation. The areas of highest gradients and intense sheared mixing are outside of the EEZ of Canada, and hence the proposed RV-based measurement campaign does not require any special permission. The land based campaign will be conducted in collaboration with Environment Canada, which has access to several sites in the two areas of interest.
Summary of Facility Requirements: We will need ship's CTD/ADCP, meteorological tower, deck space for instrument deployment and recoveries and a AUV/TLS launch location. The R/V deck instrumentation (to be supplied by the PIs) includes: motion stabilized Lidar, microwave radiometer, ceilometer, radiosonde launching station, flux tower, Sea Surface, Remote Ocean Surface Radiometer (ROSR) and a sea snake chain. In addition, periodic deployment of vertical microstructure profiler is expected.
Summary of other requirements and comments: Coordination between air traffic control and the releases of radiosondes; synergistic ship and on-land profiling with TLS systems. Both of these issues can be addressed in due course.

Requested Ship, Operating Days and Dates
Year: 2018 Ship/Facility: Hugh R. Sharp
Optimum Start Date: 9/1/2018 Dates to Avoid: August and latter part of October ought to be avoided. August does not typically have the right atmospheric condition for our research. November will not allow coordinated/synchronized measurements over land and over ocean, as the intense operational period of land-based measurements will be from Sept 1st to October 1st (afterwards, only autonomous stations will run continuously). If needed, the IOP can be extended to include the first part of October.
Earliest Start Date: 8/27/2018 Multi-Ship Op: No
Latest Start Date: 10/7/2018 Other Ship(s): N/A

Repeating Cruise?
(within same year)
No Interval: N/A # of Cruises:  

Description of Repeating cruise requirements: The measurements will be made in the where of Labrador and Gulf Stream waters meet. Some repetition of the measurement tracks are expected, but the final decision of the measurement strategy will ne made during the C-FOG planning meeting to be held on May 21, 2018.
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
We need specific atmospheric conditions that occur seasonally in Sept/October. September is preferred to allow intense coordinated measurements over land and ocean.
Due to the large number of participants and large number of measurement platforms on board we require an Ocean/intermediate class ship. This would be also crucial to allow fine-scale ocean measurements, as rough water conditions are expected.
Work Area for Cruise

Description of Op Area: The experiment is planned to be conducted in the international waters, 200 NMi east of Newfoundland , Cananda. Marsden grids of 150 & 149 is expected to be the zone of the deployment region.

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)?
Yes If yes, have you applied for the necessary permits through your export control office? No
 Questions about ITAR/EAR regulations?

Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.)
Not planning to make measurements in the Canadian EEZ. Extensive program is planned in international waters. If there is a port call in Halifax, it will be an innocent passage.
Port Calls
Requested Start Port Intermediate Port(s) Requested End Port
St. George's, Bermuda Halifax, Canada St. George's, Bermuda
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops
It is assumed that Atlantic Explorer will be stationed in St. Georges prior to C-FOG campaign. Given the 28-day endurance of the requested ocean/intermediate class vessel, a port call is suggested. Halifax, Nova Scotia, is the best choice as there will be a land based station/personnel in Halifax. The oceanographic measurements will only be conducted outside the Canadian EEZ but atmospheric measurements on RV is expected to be continuous if allowed. We have permission to conduct land based atmospheric measurements via an agreement with Environment Canada. We will carefully review all requirements and restrictions.
