Dataset Card for Amfitrite Open Waters HAB Sentinel2 This dataset contains multispectral Sentinel 2 satellite imagery tiles focused on open water and coastal marine environments, classified by the potential presence of Harmful Algal Blooms (HABs). It is designed to train Machine or Deep Learning models (like CNNs) for large scale environmental monitoring and ocean anomaly detection. Dataset Details Dataset Description Amfitrite Open Waters HAB Sentinel2 is a specialized dataset designed for the detection and classification of Harmful Algal Blooms (HABs) in open waters. The dataset consists of 2,982 multispectral image tiles derived from Sentinel 2 satellite imagery. It features a carefully balanced and curated collection of imagery: 1,445 HAB tiles 1,317 non HAB tiles 110 pure cloud distractors ( 99% of pixels labeled as clouds in the SCL map) 110 pure land distractors ( 99% of pixels labeled as land in the SCL map) The annotation methodology integrates in situ cell count measurements from 9 different global datasets, spatial grid sampling to mitigate coordinate inaccuracies, predictions from the CyFi tool and cross validation against 4 distinct Deep Learning models previously trai…
