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 (NW Spain) from samples collected monthly at a shelf station off A Coruña between 1989 and 2016.
These series are part of the long-term observational project RADIALES (Instituto Español de Oceanografía, IEO, Spain).

Comment:
Method comment:
1) Chla: filtration (Millipore cellulose acetate 0.8 µm pore-size until 1992; Whatman GF/F filters from 10992 onwards), extraction in 90% acetone overnight (-20°C) and measured fluorometrically (until 2000) or espectrofluorometrically (from 2000 onwards). Intercallibration adjustments between methods were made to ensure the compatibility of the series for the entire sampling period. References: Parsons et al. 1984; Neveux and Panouse 1987.
2) PP: 14C-bicarbonate uptake.in situ-simulated incubations for 2h at noon. Reference: Bode et al. (2011).
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)
