Scientific objective: The main objective is to examine the relationship between the molecular composition of Dissolved Organic Matter (DOM) and the diversity and activity of microorganisms in the coastal upwelling system of the NW of the Iberian Peninsula.
1) Study the effect of DOM diversity on the microbial activity in the upwelling system of the NW of the Iberian Peninsula at different spatial and monthly scales.
2) Study the effect of DOM diversity on the microbial diversity in the upwelling system of the NW of the Iberian Peninsula at different spatial and monthly scales.
Cruise programme: The RADIALES program (http://www.seriestemporales-ieo.com/) has been conducting research cruises at approximately monthly intervals since the 1990s (Casas et al. 1997, 1999, Bode et al. 2012) with the objective of monthly monitoring the oceanographic conditions and the plankton of the Atlantic coast of the north of Spain. For this proposal we will collect samples on board B/O Margalef in the Radial of Santander (several station located in the transect 3º 47.0 W), Gijón (several stations located in the transect 5º 32.8 W), Cudillero (several stations located in the transect 6º 08.0 W), A Coruña (core Station 2, 8.5 ºN; 8º 57.5'W), Vigo (core Station 3 43°25.3'N;8°26.2'W) located in the north coast of the Iberian Peninsula and with ≈100-400 m depth. An overview of the time series of this station can be found at http://www.st.nmfs.noaa.gov/copepod/time-series/es-50102).
