Measurements of CO2 fluxes and bubbles from a tower during ASGASEX
conference paper
The Air-Sea Gas Exchange experiment ASGASEX was conducted from August 30 until October lst from the Meetpost Noordwijk (MPN), a research tower in the North Sea at 9 km from the Dutch coast. The objective of ASGASEX was a study of parameters affecting the air-sea exchange of gases, and a comparison of experimental methods to derive the exchange coefficient for CO2. A detailed description of the ASGASEX experiment is presented in Oost (1994). Our contribution to ASGASEX was a micro-meteorological package to measure the fluxes of CO2, momentum, heat and water vapor, and an instrument to measure the size distribution of bubbles just below (0.5-l m) the sea surface. In this contribution we report preliminary results from the CO2 flux measurements and the bubble measurements. The latter were made as part of a larger study on the influence of bubbles on gas exchange (e.g., Woolf, 1993) in cooperation with the University of Southampton and the University of Galway (see Oost, 1994).
