EARTH SCIENCE ARCHIVE
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.
Precipitation Extremes Drive Swings in Lake Tahoe’s UV Exposure
An 18-year study reveals dramatic year-to-year variations in ultraviolet radiation penetration tied to Sierra Nevada precipitation cycles.
Water Tracks: The Veins of Thawing Landscapes
Tracing and tracking change in permafrost flowpaths could reveal the dynamics of warming poles.
