dc.description.abstractObservations were conducted in a time series mode off Visakhapatnam in Bay of Bengal, for a period of 10 days from 8 to 19th February 2013 to examine the short-term atmospheric events on chemical processes in the upper 100 m water column. Water column temperature, salinity at 2 h interval from surface to 100 m were collected using CTD whereas water samples were collected for nutrients (phosphate and silicate), dissolved inorganic carbon (DIC), pH, total alkalinity (TA) at 4 h interval in the upper 25 m water column. Atmospheric properties such as air temperature, humidity, and wind speed were measured in 1 min interval. The winds were normally northeast direction with speed ranged between 0.1 and 8 m/s from 8 to 13th February and decreased to 0.1–4 m/s between 14 and 19th February 2013. The atmospheric pCO<sub>2</sub> ranged from 380 to 420 μatm whereas surface water pCO<sub>2</sub> ranges from ~370 to 470 μatm during study period. The low pCO<sub>2</sub> levels were associated with low saline water indicating the rich nutrient coastal waters were under saturated with reference to atmosphere. The CO<sub>2</sub> flux estimations for this region showed a significant source to the atmospheric CO<sub>2</sub>. This study provides information on changes in the physical and chemical processes in relation to the CO<sub>2</sub> flux at the air-water interface in the coastal Bay of Bengal
