syneruptively

— Carbon dioxide is one of the most common magmatic gasses and is often emitted at submarine hydrothermal and eruptive vents (e.g., Chadwick, Cashman, et al., 2008; Lupton et al., 2006). Chadwick et al. (2014) observed CO2 bubbles emerging from the eruptive vents at NW Rota-1 detach from the syneruptively generated sulfur-rich plumes and rise higher in the water column before eventually dissolving. Our observations provide evidence that CO2 appears to behave similarly at Hunga.
