Total electron content data at three GPS stations in Yellowstone National Park

Total electron content (TEC) data—a measure of activity in the ionosphere—at three GPS stations in Yellowstone. Each line color is a measurement using a different satellite passing overhead. Note how the data are steady until the evening of May 10, 2024, when the signals start to fluctuate wildly due to the arrival of the Coronal Mass Ejection.

Illustration of the crystal growth process that leads to melt inclusion entrapment. (a) A crystal (gray area) nucleates and grows. (b) As the magma cools, the crystal corners will grow more efficiently than crystal edges. (c) This growth process will lead to the entrapment of surrounding melt (orange area).

Plot of specific conductance, discharge, and temperature measured at the Yellowstone River at Corwin Springs, Montana, during early-mid 2023. The anomalous spikes in temperature and specific conductance on May 23, 2023, are thought to be when a large sand and bar was deposited at the site. May 23 is also the peak flow in 2023.
