My study aims to quantify water vapor, CO2, and heat exchange between the eastern water bodies and the atmosphere along the low-lying Jordan Valley, Israel. The valley is quite unique, as it captures both a thermal and salinity gradient – from a salty dead sea in a hyper-arid environment to Lake Kinneret and Hula wetland, characterized by freshwater in a Mediterranean climate. Moreover, these water bodies, formed due to tectonic subduction by the active dead-sea transform fault, are highly sensitive to climate change. This is demonstrated by high and low stands, developed during periods of climate change. Hence, I wish to first understand the modern mechanisms that control these water bodies' evaporation, CO2, latent and sensible heat fluxes. And second, to understand the Jordan Valley paleoenvironment variations during periods of past climate change. To do so, I am using the eddy covariance method, a state-of-the-art approach, that directly measures micrometeorological data, alongside synoptic-scale analysis.
