Geophy. Res., xxx (Cx),doi:10.1029/2003JC002131, 2004 Introduction This dataset contains data obtained during the Coastal Ocean Processes Program (CoOP) Coastal Air-Sea Chemical Fluxes study conducted from the R/V Oceanus in coastal and offshore waters south of Cape Cod, Massachusetts in June/July, 1997. The data set includes 15-minute averages of wind speed, friction velocity, heat transfer velocity, gas transfer velocity, mean square slope, CDOM fluorescence of subsurface water and the difference between microlayer and subsurface CDOM fluorescence, the latter used as a proxy for surface film enrichment. 1. 2003JC002131-TABLE2.txt Data supporting Figures 3- 5, 7, 8, 14 and 15: 1.1 Column "Yday_decimal", Decimal yearday, 1997. 1.2 Column "U_10", m/s, Wind speed at 10 m height and neutral buoyancy. 1.3 Column "u_star", cm/s, water-side friction velocity. 1.4 Column "k_h", cm/hr, heat transfer velocity. 1.5 Column "n_1", Schmidt number (Sc) exponent used to scale heat transfer velocities to Sc = 660 in Figures 3, 5, and 7. 1.6 Column "k_gas_1", gas transfer velocity at Sc = 660, scaled from k_h using n_1. 1.7 Column "n_2", ", Schmidt number (Sc) exponent used to scale heat transfer velocities to Sc = 660 in Figures 4 (left panel), and 8 (left panel). 1.8 Column "k_gas_2", gas transfer velocity at Sc = 660, scaled from k_h using n_2. 1.9 Column "n_3", Schmidt number (Sc) exponent used to scale heat transfer velocities to Sc = 660 in Figures 4 (right panel), and 8 (right panel). 1.10 Column "k_gas_3", gas transfer velocity at Sc = 660, scaled from k_h using n_3. 1.11 Column "mss_40_800", mean square slope obtained from integration of the slope spectrum over the wave number interval 40-800 radian/m. 1.12 Column "mss_40_100", mean square slope obtained from integration of the slope spectrum over the wave number interval 40-100 radian/m. 1.13 Column "mss_100_200", mean square slope obtained from integration of the slope spectrum over the wave number interval 100-200 radian/m. 1.14 Column "mss_200_400", mean square slope obtained from integration of the slope spectrum over the wave number interval 200-400 radian/m. 1.15 Column "mss_400_800", mean square slope obtained from integration of the slope spectrum over the wave number interval 400-800 radian/m. 1.16 Column "CDOM", CDOM (chromophoric dissolved organic matter) fluorescence measured for subsurface water at 10 cm nominal depth; excitation wavelength = 255 nm, emission wavelength = 350 nm; 1 unit is equivalent to the fluorescence of a 1 ppb quinine sulfate standard. 1.17 Column "CDOM_delta", Surface microlayer CDOM fluorescence minus subsurface CDOM fluorescence.
