Terri Cook

Terri Cook is an award-winning freelance writer whose career has focused on exploring and explaining the 4.5-billion-year-history of the remarkable planet we live on. Cook, who has an M.S. degree in Earth science from the University of California, Santa Cruz, writes about geology, ecology, and the environment—as well as wine, tea, hiking, and biking—for a diverse group of publications, including Eos, Scientific American, NOVA Next, Science News, and EARTH magazine, as well as Avalon Travel and numerous other travel-related publications. Her reporting has taken her to 25 states and 20 countries scattered across 5 continents, from the depths of the Grand Canyon to the sandy Australian Outback to the mist-shrouded summit of Bali’s Mount Batur. As the coauthor of three popular guidebooks, including Hiking the Grand Canyon’s Geology and Geology Underfoot Along Colorado’s Front Range, Cook gives frequent presentations about geology and science communication. She is the recipient of a 2016 European Geosciences Union Science Journalism Fellowship and is based in beautiful Boulder, Colo.

Harnessing Remote Infrasound to Study Volcanic Eruptions

by Terri Cook 30 April 20182 May 2022

Data from the 2015 eruption of Chile’s Calbuco volcano suggest the international network built to monitor nuclear explosions may also be used to detect and characterize volcanic activity.

Evidence of Extensive Ice Deposits Near Mercury’s South Pole

by Terri Cook 20 April 201810 January 2023

New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.

Dust Does Not Control Surface Ocean Productivity

by Terri Cook 4 April 201819 October 2021

The first continuous comparisons between daily atmospheric dust and ocean productivity measurements indicate that they are not correlated in the Gulf of Aqaba’s nutrient-limited ecosystem.

Widespread Mantle Upwelling Beneath Oceanic Transform Faults

by Terri Cook 13 March 20188 July 2024

A global characterization of mantle flow patterns beneath active oceanic transforms suggests pervasive upwelling stabilizes divergent plate boundaries by warming and weakening these enigmatic features.
