SUCCES3 cruise biogeochemical dataset (1): SuperSucker data, ammonium and nitrate+nitrite

High-frequency beogeochemical dataset of cross-sections along the central Oregon shelf acquired during the cruise SUCCES3, from 30 July to 10 August 2009. The dataset includes: - Day of year (UTC), longitude (W), latitude (N), profile number. - SuperSucker data: altitude from seabed (m), depth in the water column (m), distance from start of the transect (km), distance from coast (km), bottom depth (m), pressure (dbar), temperature (C), salinity, density anomaly (calculated from pressure, temperature and salinity, kg m^-3), dissolved oxygen (calibrated with discrete samples, µM), and beam attenuation (m^-1). - <em>In situ</em> dissolved inorganic nutrients analysis: ammonium (µM) and nitrate+nitrite (µM). Continuous biogeochemical <em>in situ</em> data were processed first correcting with standards, after, filtering to remove extreme values, and finally, synchronizing with depth and temperature based on a known sample-flow lag based on <em>in situ</em> and surface salinity measurements.
