Abstract

Pump CTD profiles include data on time, latitude, longitude, depth, h2s, o2, sulfide, pH, po4, NO3, NO2, NH4, SiO2, fluorescence, turbidity, density, temperature, and salinity from six stations in the Baltic Sea collected between September 20 - 27, 2021. Data was collected from the R/V Elisabeth Mann Borgese.

Cite Dataset

An independent pump CTD was used to collect data on macronutrients, described by Strady et al., 2008 and Schulz-Vogt et al., 2019 . Nutrient analyses were done according to guidelines of Grasshoff et al., 1999, with the precision on each nutrient being 0.01 (PO43-), 0.02 (NO3-), 0.006 (NO2-), and 0.05 (NH4+) µM.

 

The pump CTD was designed by groups at IOW and MPI, for the CTD in the PUMP–CTD-System a SBE911+ from SEABIRD-Electronics USA is used. Further details are provided in Strady et al., (2008). 

 

CTD sensor measurements: temperature, conductivity and pressure. Temperature and salinity are mean values obtained from Temp (ITS-90) and Salinity Practical (PSU) from CTD data. Nutrients measured with Quattro Seal: NO3, NO2, NH4 and PO4.

 

Sensors connected to pump CTD O2, H2S and pH. See supplemental files for detection limits and calibration of these sensors.
