ABSTRACT: Autonomous passive acoustic instruments remotely sense and capture sounds from a variety of…
Title: An overview of SOCCOM (Southern Ocean Carbon and Climate Observations and Modeling): ten years of studying circulation, heat, and carbon in the Southern Ocean
Abstract: The SOCCOM (Southern Ocean Carbon and Climate Observations and Modeling) program, which started in 2014, seeks to improve global climate understanding and prediction through improved observation and modeling of Southern Ocean processes south of about 30°S. This region is known to be fundamental to climate but had been absurdly undersampled, especially in…
Title: Do plants respond to variations in atmospheric humidity?
Abstract: A growing literature argues that ecosystem-scale evapotranspiration is more sensitive to drying of the atmosphere because of stomatal regulation by plants than to reductions in surface soil moisture. Past studies analysed observations, for which it is difficult to conclusively control for potential relations among plant physiology, measurable state variables such as vapor pressure deficit (VPD) or soil moisture, and ecosystem-scale water flux. Here we analyse…

Title: The South Atlantic Ocean: Circulation from an Inverse Box Model and a Multi-data Set Analysis of the Freshwater Transport by the AMOC
Abstract: The South Atlantic plays a key role in heat transport, as it hosts the returning flow of the Atlantic Meridional Overturning Circulation (AMOC). To gain insights on this role, using data from three hydrographic cruises conducted in the South Atlantic at 34.5ºS, 24ºS, and 10ºW, we identify water masses and compute absolute geostrophic circulation using inverse modeling. Our results…
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…
