Abstract:

Water column discrete observations of temperature, salinity, density, irradiance, dissolved nutrients (nitrate, nitrite, phosphate, ammonium, silicate), oxygen, chlorophyll-a, primary production (carbon uptake) rates, and particulate organic carbon and nitrogen from samples collected monthly at a shelf station off A Coruña (NW Spain) between 2017 and 2018. These series are part of the long-term observational project RADIALES (Instituto Español de Oceanografía, IEO, Spain).

Comment:

Method comment:

1) Chla: filtration (Whatman GF/F filters), extraction in 90% acetone overnight (-20°C) and measured spectrofluorometrically. Reference: Neveux and Panouse 1987.

2) PP: 14C-bicarbonate uptake. in situ-simulated incubations for 2h at noon. Reference: Bode et al. (2019).

3) POC, PON, C/N: Filtration (Whatman GF/C filters until 1996; GF/F from 1996 onwards), drying (60°C) and combustion in elemental analyzer (Parsons et al. 1984)
