©2020 Biological and Chemical Oceanography Data Management Office.SOLARIS superoxide profiles and standard CTD profiles including oxygen, turbidity, fluorescence, temperature, and PAR data from seven stations in the Baltic Sea collected between September 20 - 27, 2021. Data was collected from the R/V Elisabeth Mann Borgese.
In situ measurements of superoxide were made with a superoxide sensor, SOLARIS, which has been previously described in detail in Taenzer et al., 2022. Superoxide is quantified using a chemiluminescent method where seawater is drawn in and combines with the chemiluminescent probe methyl Cypridina luciferin analog (MCLA) in a mixing cell. MCLA reacts specifically with superoxide, and the light that is produced is quantified by a photomultiplier. Data are collected at the frequency of 2 Hz, as raw counts.
Temperature, oxygen, salinity, photosynthetically active radiation (PAR), fluorescence, and turbidity were measured by a standard CTD package and associated rosette mounted sensors (Seabird 9/11+).
