El pasado mes de Julio, la estudiante del grado en Ciencias del Mar, Irene Sánchez Méndoza, defendía su Trabajo Final de Grado (TFG). Este trabajo se centró en el estudio del sistema del CO2 entre Tenerife, La Gomera y La Palma, a través del buque de oportunidad Benchijiua Express de la compañía Fred Olsen. El resumen del trabajo (en inglés) indica:
The seasonal and annual variability of the different carbonate system variables in the western island waters of the Canary archipelago (La Palma, La Gomera, and Tenerife) were investigated for four years. Data were collected between March 2019 and May 2023 aboard a Voluntary Observing Ship (VOS). The temperature, partial pressure of CO2 expressed as fugacity (fCO2), and CO2 fluxes (FCO2) showed seasonal changes over the years. The fugacity of CO2 in seawater shows seasonal variations mainly influenced by temperature, with an increase of 9.20 μatm ºC-1 from winter to summer. The variability of the CO2 flux was controlled by wind speed and slightly by temperature. During the study period, the region behaved as a source of CO2 at 0.23 mmol m-2 d-1, showing itself as a sink during the colder months (-0.34 mmol m-2 d-1) and as a source during the warmer months (1.19 mmol m-2 d-1).
Este estudio está enmarcado en el convenio público-privado CANBIO, en el subproyecto CanOA.
