Laura Vázquez Álvarez,
alumna de Grado en Ciencias del Mar en la Universidad de Las Palmas de Gran
Canaria, ha realizado la presentación y defensa de su Trabajo Final de Grado
(TFG). El TFM, dirigido por la Dra J. Magdalena Santana-Casiano y el Dr.
Melchor González-Dávila, se titula "Carbonate Chemistry variability in
the East Coast of Gran Canaria island".
Este trabajo se ha centrado en el análisis de datos oceanográficos obtenidos en la boya oceanográfica Morgan I, localizada en la Bahía de Gando desde el 26 de Marzo de 2020. Para el TFG se han analizado los dos primeros meses.
Estos datos se enmarcan dentro del
proyecto CanOA, dentro del programa público-privado CanBIO del Gobierno de
Canarias y la Fundación Loro Parque.
A continuación se puede leer un resumen
del trabajo, en inglés.
Here it is shown the first-two-month data obtained
from the oceanographic buoy MORGAN I, set in Gando Bay the 26th of
March 2020. Physico-chemical and biological parameters were studied in order to
know the variation of the carbonate system and possible acidification. It was
seen the expected changes due to the arrival of the springtime: decreases in
oxygen concentration and pH, and rises in temperature, salinity and seawater
carbon dioxide fugacity, this last one mainly controlled by temperature
oscillations. It was also seen a relationship between SST, SSS and moon phases
caused by the variation of the tidal strength. A budget of CO2 flux
was also made, concluding that Gando Bay acts as a sink of CO2 atm,
with a rate of 15.5 tons per day for March-May. Anyway, this research is
time-limited, so it has to be continued in order to know the whole year
seasonal variation.
