 This study investigated the effects of internal solitary waves, ISWs, on the deep sea floor and its impact on benthic organisms. It found that ISWs can significantly affect the benthos, increasing the abundance and density of benthic organisms up to five times more than those not exposed to ISWs. This suggests that ISWs have a strong influence on the deep sea ecosystem, potentially altering the structure and function of the deep sea floor.
