Integrating Data to Find Links Between Environment and Health

by Zhong Liu, D. Tong, J. Wei and David Meyer 26 May 20219 September 2024

Several obstacles stand in the way of integrating social, health, and Earth science data for vital geohealth studies, but there are tools and opportunities to overcome these obstacles.

Scientists Hope Atmospheric Modeling Can Predict Meteotsunamis

Tim Hornyak, Science Writer by Tim Hornyak 24 May 202117 May 2022

The first extensively documented air pressure–driven meteotsunami on one of the Great Lakes presents an opportunity to use existing weather models to predict when these potentially deadly waves will strike.

A Comprehensive Review of Submarine Volcano Seismoacoustics

by Gregory P. Waite 19 May 202111 May 2022

Although most of Earth’s lava erupts beneath the oceans, submarine volcanoes are comparatively understudied, but a new review of submarine volcano seismoacoustics provides a framework for future work.
