Data on Europe-wide public preferences for plankton-based ecosystem services and marine biodiversity from a series of deliberative monetary valuation workshops.

Our article describes data from a discrete choice experiment conducted within a series of deliberative monetary valuation workshops. The workshops were held across Europe and explored public preferences for plankton-based ecosystem services and marine biodiversity. In total, data were collected from 15 workshops in five different countries. In each region, workshops were carried out in both coastal and inland locations. The dataset includes responses from 172 respondents, obtained between October 2023 and February 2024. In addition to respondents' preferences, socio-demographic data and other personal characteristics, postcodes, prior knowledge, beliefs and motivations were elicited. The data can be used to conduct custom analyses of preferences and willingness to pay for the aspects covered in the choice experiment, also incorporating the respondent-specific explanatory variables collected.
