In the published version of this article, there was an error in Fig. 2b. The revised Fig. 2b shows the geothermal gradient of 14 °C km^-1 instead of 17 °C km^-1, as correctly described in the figure caption of the published article.

Methane hydrates (MHs) phase stability diagram for the Adriatic Sea a at present environmental conditions (maximum depth 1212 m, salinity 3.87%, and seafloor temperature 13 °C) and b during last glacial maximum (21.5–18.3 ka BP) presumed conditions (maximum depth 1112 m, salinity 3.97%, and seafloor temperature 10 °C). The solid lines were drawn from the MHs P–T phase equilibrium data, with the pressure converted to depth assuming hydrostatic conditions in both the water and sediment and assuming seawater density of 1030 kg m⁻³. The intersections of the solid (phase boundary) and dotted lines (geothermal gradient of 14 °C km⁻¹) provide the upper and lower depth boundary of the MHs stability field. Dashed lines present the environmental conditions taken as an input for the MHSZ evaluation
