Project Description and Facility Requirements
Project Web Page:
Summary of Field Work: We will perform in situ ship wire experiments on the solubility and reaction kinetics of inorganic and biogenic calcium carbonates, including foraminifera, pteropods, and coccoliths. The study site is the Wilkinson Basin in the Gulf of Maine.

We will deploy two custom instruments which are battery powered. These instruments will be deployed on a non-conducting hydrowire at 200-250m depth for 10-24 hours at a time. A Seabird CTD will be deployed in between the two instruments. We will also potentially hang customized 1.2 L Niskin bottles above our instruments, which are triggered to close by traditional messengers. We will run at least five of these hydrowire-based experiments for a total cruise duration of 5-7 days.

Hydrocasts using a CTD/Rosette will be conducted before and after each experiment. If possible we would also like to deploy short-duration sediment traps.

We would like to catch the seasonally depressed aragonite saturation states in either the fall or spring of 2020. A regional-class ship should be of sufficient size to perform this work.
Summary of Facility Requirements: We will need a CTD/Rosette, a non-conducting hydrowire for experiment deployments (250m). Potentially an A-frame for deployment of sediment traps.
