Abstract. Past and future development of hypoxia in the Baltic Sea 1850-2098. This animation shows summer mean bottom oxygen concentration [mL /L] from a model ensemble discussed by Meier et al. (2021, doi:10.1038/s43247-021-00115-9). The time series stretches from model year 1850 to 2098 and is comprised of the historical spin up (Meier et al., 2019a,b) 1850 to 1975, the historical period (Saraiva et al., 2019a,b) 1976 to 2005 and the RCP4.5 scenario combined with the nutrient load scenario according to BSAP 2006 to 2098 (Meier et al., 2021). Oxygen concentrations below 2 mL /L indicate hypoxic areas and negative values (red colours) indicate anoxic conditions. Hydrogen sulfide is considered as negative oxygen equivalents (1 mL H2S /L = - 2 mL O2 /L).
