Underway physical oceanography and meteorological data were collected during the SO269 expedition (August, 3rd – August, 24th), on-board of the German R/V Sonne. The SO269 expedition was carried out in the frame of the project South China Sea – natural laboratory under climatic and human induced stress. Physical oceanography (temperature, salinity, chlorophyll a, turbidity, depth, conductivity, and sound velocity) together with the meteorological (air temperature, pressure, humidity, wind speed and wind direction) are of one-minute resolution.

The column "Elevation" only refers to the meterological parameters: Temperature, air * Pressure, atmospheric * Humidity, relative * Wind direction * Wind speed---The column "Depth water" only refers to the water parameters: Temperature, water * Salinity * Chlorophyll a * Conductivity * Sound velocity in water * Turbidity (Nephelometric turbidity unit)
