Talk Title: "Recent Variability in Abyssal Ocean Properties and Circulation"
Description: The bottom limb of the Meridional Overturning Circulation (bMOC) is defined by the balance between the formation of Antarctic Bottom Water (AABW) through near surface buoyancy loss around Antarctica and the integrated gain of buoyancy and return flow through abyssal diapycnal mixing. The strength of this overturning constrains ocean heat and carbon storage with direct implications for climate. Here, I examine the variability in the properties of AABW along the bMOC to provide evidence that the rate of ventilation and circulation within the abyssal Southern Ocean has significantly decreased over the past 20 years, driving the observed global scale warming of the abyssal ocean with implications for global heat and sea level budgets.
Jennifer Vanos, Assistant Professor, CASPO, Department of Family Medicine & Public Health at UC San Diego
Talk Title: "Human Biometeorology: Connecting Weather & Climate to Health"
Description: Dr. Vanos will speak about her research in the study of human biometeorology, which is an interdisciplinary science that studies the influence of atmospheric processes on human health. She focuses on human exposures to extreme heat, radiation, and air pollution within urban areas and the influence of microclimatic landscape design on said exposures. She further works to holistically understand the heat stress through human heat balance modeling and the biophysical mechanisms underlying the heat balance in vulnerable populations, such as children, in conjunction with their micro-environments. Her research transfers across scales, from regional- to city- to micro-scale, which influences the way in which researchers collect, apply, and connect weather/climate and health data. Pursuing these strategies is a vital component for human adaption to urban growth, climate variability, and small-scale extremes that influence health outcomes.
