Marine Heatwaves Characteristics in the Barents Sea Based on High Resolution Satellite Data (1982–2020)
peer reviewed Marine heatwaves (MHWs) can potentially alter ocean ecosystems with far-reaching ecological and socio-economic consequences. This study investigates the spatiotemporal evolution of the main MHW characteristics in the Barents Sea using high-resolution (0.25° × 0.25°) daily Sea Surface T...
