Is the Baltic Sea acidifying? IOW researcher adapt optical pH measurement method for brackish waters
Great advancement for pH-monitoring in the Baltic Sea: For a better observation of possible acidification trends in brackish waters, Jens Müller, marine chemist at the IOW, for the first time adapted a highly precise optical pH measurement technique for the use at low salinities, which until now was only applicable at high salinity levels of the open ocean. The newly adapted method, for which a market-ready device has already been designed, is therefore highly suitable for routine use within the framework of the Helsinki Commission's (HELCOM) Baltic Sea environmental monitoring. The work was carried out as part of the EU project BONUS PINBAL*.
