This work is part of a systematic and global re-occupation of selected hydrographic sections being carried out to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2) and related parameters. By integrating the scientific needs of the carbon and hydrography/tracer communities, major synergies and cost savings are achieved. The work consists of boundary-to-boundary sections of full-depth stations, at nominal 30-nmile spacing in basin interiors (closer at boundaries and over bathymetric features), with one deployment per station of a CTDO/rosette system with 36 10-liter bottles and LADCP. The ship's standard underway systems (including meteorology, surface seawater T/S/O2/pCO2/etc., centerline depth to bottom, navigation, hull-mounted ADCP, etc.) are also used. Program water column measurements include CTDO, salinity, oxygen, nutrients, CFCs, ocean carbon parameters, and various tracers. Differently from the 2015-2020 US GO-SHIP proposal and program, we plan to also carry out a companion bio-/ecological measurement program (a “Level 2” program in GO-SHIP terminology), with individual components and budgets proposed in separate proposals. As per instructions from NSF Program Officers, the planned number of days needed to complete the bio-/ecological measurements is listed for each cruise (indicated in the “Bio days” column of the table above). The total amount of UNOLS days requested (reported in the “Days at sea” column of the table above) includes also the days required by the bio-/ecological measurement program for each cruise. Argo float and surface drifting buoys deployments are routinely done. Requests for ancillary sampling are commonly received in the year (or more) ahead of each cruise. Please check with GO-SHIP cruise coordinator Isa Rosso for any pending or approved additions to ship time or other ship-related logistics requirements.
Summary of Facility Requirements:	CTD winch (and spare CTD winch, or spare drum if replaceable at sea on main winch); must be able to level wind the wire used; must be suitable for conducting cable; modern slip-rings in good condition; read-outs for winch speed, tension, and wire out (prefer slave/remote read-outs also available in CTD lab); control of winch payout and recovery speed steady in range 0.1-1.0 meters/second (10-60 meters/minute), with smooth low-speed "inching" during deployment and recovery; wire: UNOLS 0.322" CTD cables required on main CTD winch and spare; sheaves: adequate diameter and construction for UNOLS 0.322" CTD cable; guard to keep cable from jumping sheave when wire goes slack; anti-icing if used in icing conditions; prefer 10,000 meters wire, but require at least 1000 meters more wire than depth of deepest cast; wire history available; lubricant/dressing history and chemical composition available if CFCs or trace organics are to be measured. The estimated, separately-proposed bio-/ecological program would require a daily rosette cast to 1500 meters (a cast every station on ARC01). The most time-efficient approach would be to use a separate CTD/rosette system deployed via a (possibly portable) CTD winch outfitted with at least 2000 meters of standard CTD cable, via a separate sheave on the ship. If that or other suitable separate bio-/ecological rosette/winch/sheave system cannot be procured, and if it is necessary to use the GO-SHIP rosette, our preliminary estimate is that this would double the extra ship time needed for the bio-/ecological casts for each requested cruise. We will use nearly all lab space on a UNOLS Global-class ship, plus at least one lab van and 1-3 storage vans. No radioisotope use - in fact, the ship must be swab-tested to be "clean" for 14C and tritium. Some cruises use 50 or more standard compressed gas cylinders. Normal ship's underway systems (including pCO2) are required on all program cruises.
Summary of other requirements and comments:	Rosso assists logistics coordination for UNOLS, USCG, and USAP cruises for the program. Rosso will hand off cruise planning to the chief scientist for each cruise. The chief scientist is selected by the science oversight committee (chairs: L. Talley and G. Johnson) ca. one year ahead of each cruise. Swift is an unfunded co-Investigator (not co-PI) who is a senior advisor for US GO-SHIP, with special focus on logistics. Ports listed are commonly-used ports, convenient to the ends of the transects. Other ports can be used, but may change total days required at sea for a given cruise. It is common for the GO-SHIP program to receive requests for additional sampling, sometimes requiring extra ship time, ahead of a given cruise. (These are called “Level 3” programs in GO-SHIP terminology.) NSF has asked that, whenever possible, such requests be made at least one year ahead of a given cruise so that agency consideration can be given to the impacts and costs of the extra Level 3 days. Please check with GO-SHIP cruise coordinator Isa Rosso for any pending or approved additions to ship time or other ship-related logistics requirements. A new component of the US GO-SHIP sea program, separately proposed, will be “Level 2” bio-/ecological measurements, with individual components and budgets proposed in separate proposals. At the direction of NSF Program Officers, a preliminary estimate of the ship time and ship resources required for the Level 2 bio-/ecological program is included in these ship time requests (as opposed to being included in the separate bio-/ecological proposals). We estimate the extra ship time at approximately 1 day for every 24 GO-SHIP days at sea, except for the ARC01 cruise, where there would be a bio-/ecological cast at each station. These extra days have been itemized as “Bio days”. As per present practice and Program Officer instructions, approximately one year ahead of each requested cruise, the ship time, technical and personnel resources, and budgets required for each upcoming cruise will be examined and negotiated. Shipboard complement for the core program is about 27 persons, not including foreign observers (if required), resident technicians, persons from enhanced outreach/educational opportunities, or personnel from add-on ancillary programs (typically 1-12 extra persons). On some cruises all available science berths on global-class research ships are utilized. There is confusion regarding the definitions of terms on the UNOLS ship time request forms in terms of days requested. Due to complicated loading, each cruise requires 4 days on in-port loading (except for 1 or 2 cruises with multi-day transits to the first station, in which case 3 full days of loading may be sufficient). Each cruise also requires 2 days in port at the end of the cruise for unloading, except when the final stations are very close to port, in which case an extra day in port may be required to analyze the final samples from sea. For cruises with intermediate port stops, we request 2 nights in port (3 UNOLS days). Ship operators may require more time, in which case their extra time should be added to the 3 days.

Optimum Start Date:	1/1/2021	Dates to Avoid:	This cruise operates in the Atlantic Ocean, in the range of latitudes affected by hurricanes. Hurricane season in this part of the globe is from 1 June to 30 November; hence, it should not be carried out during that time. This is the A20/A22 cruise. If the ports change, the days at sea will need to be updated.

requirements that could affect choice
of ship in scheduling.

Dynamic positioning is used to hold station position and maintain wire safety. Multibeam is used only in "raw" mode to inspect bathymetry along track and near stations. Centerline depth to bottom is, however, required along track and at stations. Ship must be swab-tested to verify lack of contamination for 14C and tritium. There is usually one lab van and 1-2 storage vans for this program.

and provider for "other" systems.

To accommodate the requests from the companion bio-/ecological measurement program, a portable winch to operate with 2000 meters of 0.322" standards UNOLS CTD wire will be requested.

In addition, we normally use a PMEL-supplied lab van for the DIC measurements. There will be 1-2 science-supplied storage vans as well.
