Biography

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.

The flat Australian outback overlies a series of ancient mountain chains.

Research Spotlight 5 November 2018

Unraveling the Origins of Australia’s Ancient Mountain Chains

New data synthesis suggests that varying rates of trench retreat along the margin of the Gondwana supercontinent were responsible for the curvature of the Tasmanide mountain chains.

Geology & Geophysics

An updated Antarctic Magnetic Anomaly Map helps researchers study the structure of lithosphere around the South Pole.

Research Spotlight 24 October 2018

A More Detailed Look at Earth’s Most Poorly Understood Crust

The second-generation Antarctic Digital Magnetic Anomaly Project offers a powerful new tool for probing the structure and evolution of the southernmost continent’s lithosphere.

Atmospheric Sciences

Researchers measure wind speeds to understand turbulence in nighttime inversions of the stable boundary layer.

Research Spotlight 21 September 2018

Wind Speed Governs Turbulence in Atmospheric Inversions

Measurements made during a field campaign in Idaho indicate that the speed of winds 2 meters above Earth’s surface determines the type of turbulence present in nighttime inversions.

Biogeosciences

Satellite image of Point Barrow, Alaska. A 40-year record of carbon dioxide concentrations in Alaska offers insight into how the carbon cycle responds to temperature.

Research Spotlight 21 September 2018

Autumn Warming No Longer Accelerating Carbon Loss in the North

An analysis of Point Barrow’s 40-year record points to the importance of calculating the carbon cycle’s response to temperature during the northern latitudes’ non-growing season.

Planetary Sciences

Research Spotlight 13 August 2018

Evidence of Regional Deposition in Mars’s South Polar Deposits

Shallow Radar correlation of discrete units in one of the Red Planet’s largest ice reservoirs suggests that its material was emplaced as a single, regional deposit.

Ocean Sciences

Researchers look at the traces of icebergs in the Norwegian Sea to better understand the past behavior of North Atlantic currents

Research Spotlight 1 August 2018

Scraping Bottom: Iceberg Scours Reveal North Atlantic Currents

A 3-D seismic analysis of Pleistocene iceberg gouges indicates that surface currents in the Norwegian Sea flowed northward and remained consistent during numerous glacial cycles.

Hydrology, Cryosphere & Earth Surface

Researchers recreate streams in the lab to study sediment pulses

Research Spotlight 24 July 2018

How Are Sediment Pulses Generated?

A new long-term flume experiment shows that bed load gravel travels downstream in recurring, 10-hour pulses even when water flow and sediment supply are constant.

Ocean Sciences

Researchers use seafloor pressure sensor data to examine how infragravity waves are reflected back to shore by the edge of a continental shelf

Research Spotlight 23 July 2018

On the Origin of Infragravity Waves

Seafloor pressure sensor data show that long-period ocean surface waves radiating from the world’s shorelines are mostly reflected back to shore by the continental shelf edge.

Space Science & Space Physics

Satellite observations offer a glimpse of how Kelvin-Helmholtz waves behave in Earth’s magnetic tail

Research Spotlight 20 July 2018

Measurements of Kelvin-Helmholtz Waves in Earth’s Magnetic Field

Simultaneous satellite observations from different distances of Earth’s magnetic tail offer insight into how these instability waves evolve through time and space.
