| Cruise Info. | |
| Ship name (ship code) | RV Atlantic Explorer (33H4) |
| Cruise identifier | AE1921 (BAIT-III, GApr13) |
| Cruise period | 2019-08-16 — 2019-08-22 |
| Status | Completed |
| Port of departure | Bermuda, Bermuda |

| Purpose | Research |
| Objectives | In a joint NSF-NERC project (funded), field data from the Bermuda Atlantic Time-series Study (BATS) region will be combined with an established, state-of-the-art ocean biogeochemical model in order to constrain the pools, fluxes and physicochemical transformations that control the oceanic distribution of dissolved iron (dFe), thereby advancing our ability to model the ocean iron cycle and project its sensitivity to future change. Specifically, seasonally resolved data on the vertical (upper 2,000 m) and lateral (tens of km) distributions of particulate, dissolved, colloidal, soluble and ligand-bound iron species will be obtained from the chemical analysis of water column samples collected during five cruises, spanning a full annual cycles, shared with the monthly BATS program cruises. These data, along with ancillary data from the BATS program, will be used to test and inform numerical modeling experiments, and thus derive an improved understanding of the mechanisms that control the distribution and dynamics of dFe in the oceanic water column. |
