Chromophoric Dissolved Organic Matter (CDOM) Napierian Absorption Coefficients from the North Atlantic Subtropical Gyre from R/V Atlantic Explorer AE1707, AE1829, AE1820, AE1905 from 2017-2019 (MODIE project)
Abstract:
These data are chromophoric dissolved organic matter (CDOM) Naperian absorption coefficients (ag) of seawater from the North Atlantic subtropical gyre, collected as a part of the OCE-1635618 project, “Transforming our understanding of DIC Photoproduction in Oceanic Waters”. The goal of the project was to investigate and constrain the photoproduction rates and efficiencies of dissolved inorganic carbon (DIC) from photochemical degradation of dissolved organic carbon in the open ocean, which could provide better estimates of DIC photoproduction flux in the open ocean and improve carbon budget modeling.
The surface (1 m) and deep (3000 m) seawater samples were collected using Niskin bottles mounted on a CTD rosette, for photoirradiation experiments, during Bermuda Atlantic Time-series Study (BATS) cruises in May 2017, July 2018, October 2018, and April 2019 aboard the R/V Atlantic Explorer. ag were measured with spectrophotometers.
