Australia committed to restore 30% of degraded ecosystems by 2030 when we signed the global biodiversity framework. But what does that really mean? It’s open to interpretation. So let’s be ambitious.

Mathematical Models for Evaporating Sessile Droplets

The evaporation of a sessile droplet is a multifaceted problem of enduring scientific interest that is key to a wide range of everyday and industrial situations, such as protein crystallography, surface patterning, ink-jet printing, and agrochemical spraying of plants. In this talk I shall review some of the recent developments in the study of evaporating droplets, focusing on situations in which relatively simple mathematical models can give new insights into this fascinating multidisciplinary problem, including the competitive evaporation of multiple droplets, the evaporation of a droplet on a non-planar substrate, and the effect of the spatial distribution of the local evaporative flux on the deposit left on the substrate by a particle-laden droplet. The results presented in this talk are the outcome of joint work with a large number of collaborators, including Drs Brian Duffy, David Pritchard and Alexander Wray (University of Strathclyde), Professor Khellil Sefiane (University of Edinburgh) and Professor Colin Bain (University of Durham), and past and present research students Gavin Dunn, Jutta Stauber, Feargus Schofield, Hannah-May D’Ambrosio, Laura Mills, David Craig and Henry Sharp, all of whose invaluable contributions are gratefully acknowledged.

What are the challenges simulating historical ocean deoxygenation?

Global warming is causing a decrease in the amount of dissolved oxygen (o2) in the ocean, which is a major issue for marine ecosystem and sea life. However, we face challenges in accurately predicting these changes in o2 levels using our current models. In this presentation, I will talk about the uncertainties and missing pieces in our ocean biogeochemistry simulations. Specifically, I will look at the latest models that simulates how the o2 and temperature have changed over the past 50 years. I will closely look at o2 and heat in the top 700 meters of the ocean, using models from the Coupled Model Intercomparison Project Phase 6 (CMIP6). I will compare changes in o2 levels and ocean heat content (OHC) to show how the ocean’s physical and biogeochemical response to climate change differ. These comparisons use forced ocean-only models (from the Ocean Model Intercomparison Project phases 1 and 2, or OMIP1 and OMIP2 ) and coupled climate models (from CMIP6 ’s historical simulations). The models show different trends in o2 and OHC over the past five decades. A closer look at the OMIP1 and OMIP2 models suggests that different atmospheric forcing such as surface wind could explain why these models simulate different changes. Furthermore, comparing OMIP models with CMIP6 historical models reveals that differences in the background mean state of the models, due to how they were initially set up and spun-up, lead to significant differences in how they simulate o2 levels will change due to climate change. Finally, I will discuss how future studies could improve our understanding of ocean deoxygenation and biogeochemistry changes by using coordinated simulation efforts. This could help us figure out what controls changes in o2 levels and other related aspects of the ocean biogeochemical cycles.
