Capturing Community Voices: A Regional Survey of Tracer Hydrology across Latin America and the Caribbean

A voluntary online survey was coordinated between July and August 2025 as part of the regional Isotope Hydrology Seminar Series. The survey targeted 82 researchers and practitioners across Latin America and the Caribbean, with 45 completed responses (55% response rate). Respondents provided demographic details and answered 21 structured questions covering tracer sampling, water sources, isotopic and geochemical tracers, sampling frequency, modeling approaches, database size, costs, and data accessibility. Additional topics included publication outputs, repository contributions, data end-users, citizen science, policy applications, and resource needs. Responses were compiled and analyzed in R to identify common practices, critical gaps, and opportunities for strengthening tracer hydrology in the region.
