EARTH SCIENCE ARCHIVE
Machine Learning Model Flags Early, Invisible Signs of Marsh Decline
Decreases in underground plant biomass could signal future marsh loss and prompt conservation measures.
A Transatlantic Communications Cable Does Double Duty
A new device enables existing submarine cable networks to measure deep-sea movements. It could ultimately help improve tsunami warnings and climate monitoring.
How Plants Respond to Scattered Sunlight
A new study investigates how diffuse light affects evapotranspiration and carbon uptake across forest, grassland, shrub, and agricultural areas.
Mapping Mud Volcanoes in Shallow Seas
A team of scientists put together a global database of submarine mud volcanoes. Orders of magnitude more are still bubbling, undiscovered, in the deep ocean.
Biomass and Biodiversity Were Coupled in Earth’s Past
Measuring shells and skeletons encased in thousands of limestone samples has revealed that the sheer amount of living stuff in Earth’s oceans changed alongside the diversity of organisms.
Deep Root Respiration Helps Break Down Rocks
The carbon dioxide that results from respiration in and around deep roots is an essential component in the chemical weathering of sandstone rock soils.
Environmental Groups Sue to Block Everglades Detention Facility
The groups assert that the facility will undermine decades’ of work and billions of dollars spent restoring and protecting the Everglades’ delicate ecosystem.
New Satellite Adds Evidence of an Earth-Shaking Wave
A tsunami struck a fjord in East Greenland in 2023, ringing seismometers for nine straight days. A new satellite study provides the first observational evidence of the waves.
Hydrothermal Hazards on Display in Yellowstone National Park
Tourists and officials were startled by a hydrothermal explosion at Black Diamond Pool in July 2024. Geoscientists are working out how and why it occurred to better understand these hazardous events.
Shedding Light on the Mysteries of Deep Earthquakes
By analyzing forty deep earthquakes around the world, researchers discover the key role of a dual mechanism that allows earthquakes to grow larger and release more stress.
