Experiments, field sampling, and remote sensing were employed, to estimate the seasonal variation of the BP and the abundance of cells in the northwestern Arabian Sea. An experimental setup for BP measurements integrated a “Chelsea Instruments” GlowTracka sensor, which required ~5 N. scintillans cells to obtain a statistically robust signal.

The remotely sensed chlorophyll-a concentration was analyzed, for the period from 2000 to 2022. A positive linear relationship between the abundance of N. scintillans cells in experiments and their BP was elucidated.
