©2026 Biological and Chemical Oceanography Data Management Office.This dataset contains 48 samples of particulate organic carbon collected from the lower Amazon River from May 1st-12th, 2023. The tabulated data include sample number, date, latitude, longitude, sample type, fraction modern radiocarbon (Fm), Δ14C, δ13C, and molar C/N ratio for suspended sediment, bedload, and bank/flood-deposit samples. Sampling was conducted at discrete sites along the lower Amazon mainstem and nearby depositional environments, so spatial coverage is variable rather than unifo...
