... Abstract Green tides have occurred in Jinmeng Bay (JMB) since 2015. Wind field is a very important physical factor controlling the migration of green algae. Based on MIKE 21, a particle tracking model was established to simulate the movement of green algae driven by wind and tide. The results...

.... Furthermore, localised absorption effects from gas pockets lead to dimming amplitudes for events beneath them. To deal with these issues, we propose to use time-lag full wave-form inversion (TLFWI) to resolve the velocity of complex overburdens and least-squares Q prestack depth migration (LS Q-PSDM) to...
