These data were collected through an online survey hosted on Qualtrics software. The survey was designed to understand perceptions of coastal landscapes, specifically dykes, dykelands, and tidal wetlands, along with coastal adaptation options, specifically managed realignment and flood risk mapping, among residents of the Minas Basin region of Nova Scotia, around the Bay of Fundy. Recruitment was conducted through a multiple-reminder mailout of a simple random sample of the Nova Scotia Residential Dwelling Characteristics dataset (2022), rendering a response rate of 21%. Participants were rewarded with the option to enter to win one of twenty Tim Hortons or Irving Gas gift cards. Permission to make data public was a condition of participation, and all 'free text' questions have been removed to avoid the possibility of identification.
