Short summary
Seasonal monsoon storms over South Asia and the northern Indian Ocean bring heavy rains and thick clouds, decreasing how much sunlight reaches the ocean. We used new autonomous instruments to show that cloudy periods reduce subsurface ocean productivity by more than half, with ripple effects through the food web. These short-term shifts are as large as seasonal changes in productivity and influence how the ocean stores carbon.
