Element concentrations from two benthic chambers and the ambient bottom water during an in-situ incubation experiment in July 2025

Description: The dataset contains major and trace element concentrations measured by inductively coupled plasma optical emission spectrometry (ICP-OES) from water samples collected during a 16-day in-situ incubation experiment in the Baltic Sea (2025-07-12 to 2025-07-29). Samples were collected using an automated glass-syringe sampler deployed within two benthic chambers of a Biogeochemical Observatory (BIGO, Sommer et al., 2009) at 54° 34.432' N, 10° 10.776' E, at 22 m water depth. In one chamber, 29 g of fine calcite powder were added to the bottom water to assess the potential of enhanced benthic calcite weathering as an ocean alkalinity enhancement (OAE) strategy. Seven samples per chamber and from the ambient bottom water were analyzed to trace elemental changes associated with calcite dissolution.
