Project Title: RAPID: Fate of freshwater and heat in the West Greenland Current Project Status: Submitted
Principal Investigator: Robert S. Pickart, WHOI Project Institution: WHOI
Project ID: 106829 Version #: 1
Date Submitted: 5/25/2020 7:34:00 PM Created By: Robert S. Pickart

Funding Agencies: NSF/OPP/ARC - 2034801 - Funded
Summary of Field Work: This is a hydrographic cruise to determine the evolution and fate of the Arctic-origin freshwater, Greenland meltwater, and subtropical-origin warm water in the West Greenland Current. Sections will be occupied from the southern tip of Greenland to Nares Strait, including detailed measurements in several troughs that lead to glacial fjords along the West Greenland Coast. Extensive mapping will be done in Baffin Bay to measure the inflows, outflows, and recirculation. In addition, we will do a detailed survey of one of the large eddies shed by the West Greenland Current. Collaborative projects will include glider work and chemical sampling to distinguish the sources of freshwater.
Summary of Facility Requirements: The activities include conductivity-temperature-depth (CTD) work, water sampling, use of expendable probes, and underway sampling. We will use the starboard CTD system, underway systems, vessel-mounted ADCPs, and bathymetric systems. Glider deployments and recoveries will be done.
Summary of other requirements and comments: We will rely heavily on CTD work and vessel-mounted ADCP measurements.

Requested Ship, Operating Days and Dates
Year: 2021 Ship/Facility: USCGC Healy
Optimum Start Date: 9/7/2021 Dates to Avoid: We are completely flexible to fit into Healy's schedule, and will accommodate our work plan based on the length of time available for the fall 2021 science leg. We are requesting 40 days, but a 35-day leg will allow us to complete the majority of our objectives.

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

Canada, Greenland
 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?

Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.)
We will need clearance to sample within 1nm of the Labrador/Baffin Island coast as well as the West Greenland coast.

Explanation of Science Party Requirements and Technician Requirements We will use the CTD/rosette and starboard winch with conducting wire, underway thermosalinograph, vessel-mounted ADCPs, and bathymetric systems. We will use expendable probes and do glider work. We will carry out science operations around the clock. Technicians are needed for managing the CTD system, running salts, IT activities, and the operation of the multi-beam, Knudsen, and vessel-mounted ADCPs. Assistance will be needed with the glider operations as well.

requirements that could affect choice
of ship in scheduling.

We are taking advantage of the Healy going east in 2021. Part of the study area will have pack-ice, hence an ice-breaker is essential. We will do multi-beam mapping in the fjord troughs.
