The Gravity Recovery and Climate Experiment (GRACE) satellite mission (2002-2017) consisted of two satellites at ~500 km altitude separated by 200 km, following each other in the same orbit. The distance between the two GRACE satellites changes because of the gravitational pull of the masses beneath the satellites. As such, mass changes at or near the Earth’s surface caused variations in the dista ...[Read More]

Sea-level change serves as a direct indicator of climate change with profound implications for coastal areas. Since 1900, the global mean sea level (GMSL) has risen over 20 cm, leading to beach erosion, delta inundation, and increased flooding worldwide. Over glacial cycles spanning tens of thousands of years, interactions between ocean and continental-scale ice sheets can cause GMSL to fluctuate ...[Read More]

I hope you are ready to be inspired because we have another exciting interview, with Kristel Chanard, our Outstanding Early Career Scientist Awardee of 2022. I promise that her answers will encourage you to pursue a career in science or continue to that! Her answers remind us again that we need to make geosciences more inclusive and diverse. So, let’s leave the spotlight to Kristel and hear what ...[Read More]
