In Situ Benthic Reflectances of Gamache Bay, Anticosti Island

This dataset contains the benthic reflectance measurment made underwater (SCUBA diving) and in air, acquired in 2021, 2022 and 2023 around Gamache Bay, Anticosti Island. The data where acquired as part of the Algae-WISE project to create a database of benthic reflectance spectra used for inversion of remote sensing signal in optically shallow waters. The database include reflectance spectra of brown algae, brown algae with the epiphyte Membranipora sp., coraline algae, red algae and sediment/rock. When available algae species are recorded (Thesis Chap. 2 R. Mabit, 2026).
