This dataset, consisting of 3 separate files, provides the basis for our manuscript entitled "Saxitoxin and tetrodotoxin bioavailability increases in future oceans". Each file contains the data for one figure. For detailed calculation methods please refer to the method and supplementary information sections of the associated manuscript. Fig1_STX_and_TTX_pH-availability contains abundance data of saxitoxin (STX) and tetrodotoxin (TTX) protonation states across the pH range from 6 to 10 at 3 different temperatures. It is calculated based on published pKa data using the Henderson-Hasselbalch equation. Temperature is taken into account employing a pKa-influencing factor of -0.2/+10C.Fig2_Dinos_HAEDAT_STX_concatenated contains all the information required for plotting the pH and temperature dependent global toxicity map. It combines georeferenced records for localities with STX-related HABs (extracted from the Harmful Algal Information System metadatabase - HAEDAT) and the distribution of two dinoflagellate ... : Supplement to: Roggatz, Christina C; Fletcher, Nichola; Benoit, David M; Algar, Adam C; Doroff, Angela; Wright, Bruce; Wollenberg Valero, Katharina C; Hardege, Jörg D (2019): Saxitoxin and tetrodotoxin bioavailability increases in future oceans.
