Description

DescriptionThis dataset contains AI-based fish detections from underwater pictures collected by several cameras at the OBSEA seafloor observatory. Located 4 km offshore from Vilanova i la Geltrú, Spain (NW Mediterranean), OBSEA is a multiparametric platform that has been continuously acquiring multidisciplinary marine data since 2009. The observatory includes a seabed station and a moored buoy.The AI model is a YOLOv8 xlarge trained with labeled underwater pictures from OBSEA. The model can be found here. The dataset also contains links to underwater pictures taken by several underwater cameras at OBSEA seafloor station.General InformationPlatforms: OBSEA Expandable Seafloor ObservatorySensors: IPC608UW-10, DCS-7010L, GNC328G2-XD, Sony_SNC-RZ25N, PopUp_Cam, AXIS_P1346Coordinates: latitude 41.18212 °N, longitude 1.75257 °E, depth 20.0 mTemporal Coverage: from 2020-01-01 to 2020-12-31Sampling Frequency: variable
