McGillis 9711218 Support is provided to measure air-sea gas fluxes directly in the air boundary layer by the eddy correlation (direct covariance) method; to compare the results with the well-established method of estimating gas transfer velocities from tracer mass balances in the ocean; and to develop a parameterization of this flux (and its gas transfer coefficient) as a function of environmental forcing on shorter time scales than is possible with the mass balance technique. The techniques developed in the lab will be tested in coastal waters in 1997, and as part of carbon dioxide exchange program in the open ocean in 1998.

McGillis 9711218 支持通过涡相关（直接协方差）方法直接测量空气边界层中的海气通量；将结果与根据海洋示踪质量平衡估算气体传输​​速度的成熟方法进行比较；并开发该通量（及其气体传递系数）的参数化，作为环境强迫的函数，在比质量平衡技术更短的时间尺度上。 实验室开发的技术将于 1997 年在沿海水域进行测试，并作为 1998 年在公海进行二氧化碳交换计划的一部分。
