1. FROID and BECOOL projects: 4 fieldworks – Belgium-France consortium Coordinators (François Fripiat and Harry Zekollari) Objective 1: What control age distribution in blue ice areas? Objective 2: Drill cores (< 300 m) where the ice is the oldest Meteorites and ice dating Surface transects and short cores Radar transects and ablation stake Ice Flow Modeling Quest of the Oldest ice in blue ice area near PES Ice core drilling down to the bedrocks Tollenaar et al., 2022, Sci. Adv.; Tollenaar et al., 2024, GRL PE station
2. Greenhouse gas feedback? Climate forcings? Warmer world Marine record Antarctic T°C Is it possible to extend the ice core record back in time? Tollenaar et al., 2022, Sci. Adv.; Tollenaar et al., 2024, GRL Old ice Objective 1: What control age distribution in blue ice areas? Objective 2: Drill where the ice is the oldest Lisiecki and Raymo, 2005; Jouzel et al., 2007; Bereiter et al., 2015 EPICA Dome C (EDC) 3260m ice core
3. Blue ice near PES has strong potential to contain very old ice Etienne Legrain Postdoc VUB-ULB Veronica Tollenaar Postdoc VUB ice-dynamical flowline models Legrain et al., 2026, to be submitted soon Sensitivity to forcing parameters
