Long-term radon-222 (Rn) and hydroclimatic dataset for a coastal estuary, Corpus Christi Bay, Texas.

The dataset features radon-222 (Rn), a radioactive tracer naturally present and frequently employed to assess submarine groundwater discharge (SGD). This collection is part of a study aimed at refining SGD estimations in shallow estuaries through the prediction of Rn variations using accessible hydroclimatic parameters [1]. The dataset includes measurements of Rn in water gathered recurringly from Aug.
