ABC Fluxes Project

Atlantic BiogeoChemical Fluxes

pi

Elaine McDonagh

 Time-series of temperature, salinity and current speeds from the RAPID array at 26°N indicate that the fluxes vary on a range of timescales. ABC Fluxes addresses these issues by deploying new chemical sensors and samplers on the RAPID mooring, and by using the new observations to calculate time-series of nutrient and inorganic carbon fluxes across 26°N.

Research objectives

To calculate time series (including uncertainty estimates) of inorganic carbon and nutrient fluxes in the Atlantic at 26.5°N using a hierarchy of approaches including new observations..

EuroSea Project

Improving and integrating the European Ocean Observing and Forecasting System

aim

Overview of the EuroSea Project

EuroSea works to improve the European ocean observing and forecasting system in a global context, delivering ocean observations and forecasts to advance scientific knowledge about ocean climate, marine ecosystems and their vulnerability to human impacts and to demonstrate the importance of the ocean to an economically viable and healthy society.

WP7. Ocean Climate Indicators Demonstrator

WP7 assesses the ocean role in climate through new ocean climate indicators, and evaluates the economic value of the ocean carbon sink using a combined observing, integration, and dissemination approach. A dedicated task is focusing on carbon fluxes and uptake in the northwest Atlantic (Labrador and Irminger Seas) and the Western Mediterranean, two important areas for carbon uptake. The observations are augmented by Deep-Argo floats from EuroSea to generate user-relevant ocean-climate indicators.

my role

Task 7.1 Carbon audit of the European relevant deep convection regions

Leaded by Johannes Karstensen, task 7.1 aims to develop information products linking  in situ data from autonomous platforms, such as BGC-Argo, moored instrumentation and long-range autonomous surface vehicles (ASVs) deployed in EuroSea, with ocean color data and other observations. My role within this task links to the biogeochemical linkages between surface physical and biogeochemical constraints and the carbon fluxes, by means of the use of neural networks that will serve to estimate carbon fluxes for the North Atlantic.
