Thermometric Measurements Of The Molecular Sublayer At The Air-Water Interface, B. Ward
Thermometric Measurements Of The Molecular Sublayer At The Air-Water Interface, B. Ward
OES Faculty Publications
[1] A series of measurements was conducted in the AirSea Interaction Saltwater Tank (ASIST) to study the response of the air-water interfacial molecular sublayer under various heat flux and wind speed conditions. In-situ gradients were measured with a platinum-plated tungsten wire microthermometer, which resolved the temperature of the thermally conductive sublayer. Air-sea heat flux was controlled by changing the air-water temperature difference (ΔTAW) and the wind speed, and measurements were made for three ΔTAW regimes over a range of wind speeds. A function was fitted to the measured temperature profiles as a way of extracting the boundary …
Alteration Processes Of Alkenones And Related Lipids In Water Columns And Sediments, H. Rodger Harvey
Alteration Processes Of Alkenones And Related Lipids In Water Columns And Sediments, H. Rodger Harvey
OES Faculty Publications
Alkenones produced by the haptophyte algae are currently being used as indices of sea surface temperature in recent and past ocean environments, but limited information is available concerning the impact of biotic and abiotic processes on the integrity of these long chain lipids. This synthesis provides selected background information on major alteration processes that must be considered before such indices can be used with confidence. A number of processes in the water column and surface sediments have the potential to impact the structural integrity of alkenones and compromise their ability as temperature markers. Processes discussed include the alteration of alkenone …
