Volcanoes are amazing features and a major contributor of CO2 to the atmosphere. One challenge has been to measure the carbon isotopic signature of a volcanic plume, which tells a lot about the deep processes and can potentially help forecast eruptions. This one-hour webinar will feature John Stix (Professor, McGill University) and Fiona D’Arcy (PhD student, McGill University) joined by Gregor Lucic (Application Scientist, Picarro) as they unravel the possibilities when deploying Picarro instruments in the field.

Methane is the second most prevalent greenhouse gas emitted from human activities. Atmospheric methane concentrations have tripled since pre-industrial times, and this increase has contributed about 20% of the global radiative forcing due to long-lived greenhouse gases. Quantifying sources of methane is therefore necessary to inform future climate change mitigation policy.

In this webinar replay Felix Vogel (Researcher, LSCE) and David Kim-Hak (Product Manager, Picarro) will introduce you to identifying urban and industrial greenhouse gas sources using the Picarro G2201-i for best-in-class greenhouse gas (GHG) concentration and isotopic measurements.

In this webinar replay, learn about how Picarro's Cavity Ring-Down Spectroscopy (CRDS) technology can be used to measure soil gas flux in-situ. Dr. Nabil Saad (Picarro, Inc.) is joined by Dr. Jesper Christiansen (U. of Copenhagen) and Dr. Nick Nickerson (Eosense). Jesper and Nick have hands-on experience with Picarro's G2508 Soil Flux System and they share their experience and results in achieving lower detection limits in gas flux measurements during the webinar.

Listen to Adam Subhas (California Institute of Technology), Nick Rollins (University of Southern California) and Nabil Saad (Picarro, Inc.) discuss making accurate and precise total carbon and δ13C measurements on discrete samples using a Picarro Cavity Ring-Down Spectrometer and the Liaison Introduction System. Adam and Nick will demonstrate how Picarro carbon isotope analyzers can be coupled to an Automate FX for seawater DIC measurements and solid carbonates, and to an Elemental Analyzer for organic carbon measurements and TOC. Adam will also share recent results from calcite dissolution experiments that are designed to probe the global carbon cycle and how the saturation state of the oceans can drive changes in atmospheric carbon dioxide.
