In the Baltic Sea, this process could so far not be quantified, partly due to a lack of appropriate pH observations. This study unravels a positive alkalinity trend in the Baltic Sea over the past two decades that counteracted acidification. Further, state-of-the-art spectrophotometric pH measurements in brackish waters are enabled by characterizing pH buffer solutions and the indicator dye m-Cresol purple at low salinities. Finally, pH fluctuations and their implications for benthic ecosystems are examined. %L 333.7 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00002303 %U http://purl.uni-rostock.de/rosdok/id00002303 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-diss2018-0135-7 %U https://d-nb.info/1293653497/34 %U https://doi.org/10.18453/rosdok_id00002303
