Title: Quantification of plastic pollution on global coastlines

Abstract: It is estimated that 300 million metric tonnes (MMT) of plastic are produced annually and that 4 to 12 MMT of this plastic enter the ocean every year. Although we have estimates of how much plastic enters the ocean, the fate of this plastic is unclear. The mass of plastic pollution on the ocean surface only accounts for 1% of annual inputs, so the remaining 99% of plastic mass in the ocean is “missing”. Coastlines are suspected to contain a large portion of this …

Title: Observational evidence of cold filamentary intensification in an energetic meander of the Antarctic Circumpolar Current

Talk Abstract: Eddy stirring at mesoscale oceanic fronts generates finescale filaments, visible in submesoscale-resolving model simulations and high-resolution satellite images of sea surface temperature, ocean colour and sea ice. Submesoscale filaments have widths of 𝑂(1-10 km) and evolve on timescales of hours to days, making them extremely challenging to observe. Despite their relatively small scale,…

Title: Understanding Seasonal Asymmetry in Polar Climate Change

Talk Abstract: The Arctic has warmed up to four times faster than the global average in recent decades, with far-reaching impacts on local ecosystems and global climate. Yet there is still debate over the drivers of polar-amplified warming, how they interact with each other, and their relative importance. To better understand the mechanisms of polar climate change, we investigate its seasonal asymmetries—why does the Arctic warm more in winter than in summer, and what are…

Title: Three Easy Pieces in Moist Atmospheric Dynamics

Talk Abstract: Much of our understanding of mid-latitude dynamics comes from dry models of the atmosphere. Both individual weather systems and the mean state of the mid-latitude atmosphere can be usefully studied while neglecting atmospheric water vapor, which eliminates the complications of phase changes and associated latent heat release. But despite the advantages of this simplification, it is clear that moisture does affect the mid-latitude atmosphere in profound ways. In this…

The Astrobiology Graduate Conference (AbGradCon) is a three-day conference dedicated to early-career scientists who study the complex and diverse topics that the astrobiology field encompasses. The goal of AbGradCon, organized entirely by graduate students, is to promote the scientific research of young astrobiologists, while promoting collaboration, practical training, and camaraderie. This year's conference will…
