I'm on an mCDR panel at #EGU25, but I just learned that our convener Carolin Löscher from Denmark won't be there.

She's been diagnosed with a rare and aggressive form of cancer whose expensive treatment is only available in the US and UAE.

Screenshot of the European Geosciences Union (EGU) General Assembly 2025 website showing the session details for "Session US2 – Marine Carbon Dioxide Removal: Fostering Earth Science Forces for Combating Global Warming." The session is scheduled for Friday, May 2, 2025, from 14:00 to 15:40 CEST in Room E1. It is chaired by Giulia Faucher, Carolin Löscher, and Gerhard Herndl. The program includes a 5-minute introduction, speaker presentations, a discussion on marine carbon dioxide removal (mCDR), and audience questions. Featured speakers are Louis Legendre (France), Daria Atamanchuk (Canada), and David Ho (USA). The session is hybrid with Zoom access. 🌊

#WeekendReading: Hoogakker (and 67 other people) go into the current state of low-oxygen proxies currently in use in paleoceanography. It's a small book (95 pages), more than a paper, and covers a lot. 🧪⚒️

Overview of oxygen “stage” nomenclature used in this review. From top to bottom shows the ranges most often associated with the descriptive terms OMZ, oxygen-deficient zone (ODZ), anoxia, dysoxia/hypoxia, and anoxia in seawater. Oxygen concentrations are shown on a log-linear scale along with a simplified schematic of several proxy-relevant components of other redox-sensitive reactions. Chemical concentrations other than oxygen are non-dimensional, but all relate to scales. The redox ladder is modified from Canfield and Thamdrup (2009).
