Summary

- Physical-chemical processes trace in the marine environment: The Marine Chemistry Group (QUIMA) is interested in the study of the biogeochemistry processes that control the behaviour of trace metal in the ocean. Actually, we study the kinetic of oxidation of Fe(II) and Cu(I) in seawater at nanomolar levels with oxygen and hydrogen peroxide and the effect of organic matter on the oxidation rate. We also study the interaction of phytoplankton with trace metals (iron and copper) in relation with sorption and complexation processes. Individual organic compounds characterization, behaviour under different physicochemical conditions and its interaction with trace metals in seawater is other important field of work.
- Carbon dioxide and climatic change: The Marine Chemistry Group is interested in the study of carbon dioxide system and its effect on climate change. We have participated in different cruises in the North-East Atlantic Ocean, mainly in the Canary region. We are measuring the carbon dioxide parameters, pCO2, pH and AT and CT in the Oceanic Time Series ESTOC since 1994. We have participated in the VI Framework European Project CARBOOCEAN, CARBOCHANGE, inside the VII Framework program, establishing a VOS line from Gran Canaria to South Africa using a comercial ship. Inside the VII European Framework Program we are involved in the project EUROSites to include sensors, pH and pCO2 in ESTOC site. Nowadays, we participate in the CanBIO project- CanOA subproject (Gobierno de Canarias-Fundación Loro Parque), CARBOCAN (Gobierno de Canarias), INTERREG projects PLANCLIMAC (MAC2/3.5b/244) and RESCOAST (MAC2/3.5b/314) establishing a carbon dioxide network in the Canary region with SOOP (lines and oceanogrphic buoys), with the SOOP CanOA as part of ICOS-ERIC
