Call

Modular Ocean Research Infrastructure — Initial Development and Demonstration (2021)

Vessel

PSV Atlantic Condor, Atlantic Towing Ltd.

Dates

• Mobilization: September 2-8, 2021
• Offshore: September 9-18, 2021
• De-mobilization: September 19-24, 2021

Cruise aims:

1. Mooring deployment Seacycler PPS-Plankton & Carbon Mooring
2. Water column sampling for SeaCycler, PPS and Carbon Package ‘calibrations’ extensive sampling after mooring deployments at mooring location ‘Bowtie’ sampling around mooring location for spatial context

1. Water column sampling for biogeochemistry objectives, underway samples, filters, – extended Halifax Line
2. Obtain fog and particle measurements (atmosphere)

Objectives and Science questions

1. SeaCycler and PPS testing: operation, communication, sample triggering
2. Observe late fall productivity in relation to other biogeochemical processes: air-sea exchange of gases, carbon budget, turbulence (Wallace/Atamanchuk/Bertrand/LaRoche)
3. Establish the extent to which specific coccolithophore-produced biomarkers capture the isotopic composition of the water they grow in.
