Air-Sea Trace Gas Fluxes: Direct and Indirect Measurements

The presence of trace gas fluxes over the open ocean has been evident in the detection of trace gas fluxes across the open ocean for the first time, most notable CO2, but also a comprehensive list of other gases. The primary use of direct methods is to quantify empirical coefficients in bulk measurements of the gas transfer velocity. This research shows modest chemical increase in CO2 flux at low wind speeds. As framed in the COAREG gas transfer algorithm, we include some updates to the theoretical implementation of bulk parameterizations.

High-sensitivity miniature dual-resonance photoacoustic sensor based on silicon cantilever beam for trace gas sensing

To achieve double resonance of the acoustic signal, the resonance frequency of the miniature T-type PA cell is related to the cantilever beam's first-order natural frequency to get double resonance. About 2. 26 cubic centimeters are the volume of the specially made T-type PA cell.
