Climate Change Prompts Alaska Fish to Change Breeding Behavior

IMG_6900.jpg

A new University of Washington study finds that one of Alaska’s most abundant freshwater fish species is altering its breeding patterns in response to climate change, which could impact the ecology of northern lakes that already acutely feel the effects of a changing climate.

Heat From Earth’s Core Could Be Underlying Force in Plate Tectonics

NewimagefromRowley1-9-17.png

For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth’s core. The new findings also challenge the theory that underwater mountain ranges known as mid-ocean ridges are passive boundaries between moving plates. The findings show the East Pacific Rise, the Earth’s dominant mid-ocean ridge, is dynamic as heat is transferred.

Fossils Found Reveal Unseen ‘Footprint’ Maker

Fossils found in Morocco from the long-extinct group of sea creatures called trilobites, including rarely seen soft-body parts, may be previously unseen animals that left distinctive fossil ‘footprints’ around the ancient supercontinent Gondwana.

Study of Microbes Reveals New Insight About Earth’s Geology and Carbon Cycles

Subsurface-microbiome_900px.jpg

Tiny microbes play a big role in cycling carbon and other key elements through our air, water, soil and sediment. Researchers who study these processes at Argonne National Laboratory have discovered that these microbial communities are significantly affected by the types of carbon “food” sources available. Their findings reveal that the type of carbon source affects not only the composition and activity of natural microbial communities, but also in turn the types of mineral products that form in their environment.

National Geographic Supports Volcano Research in Chile

As planning continues for humanity’s first visit to Mars, scientists still have much to learn about the planet’s physical makeup. By comparing current satellite images to similar shots of Earth, they are coming to understand how volcanic activity shaped the Red Planet, and extrapolating lessons learned to address concerns closer to home.

Release of Water Shakes Pacific Plate at Depth

A team of seismologists analyzing the data from 671 earthquakes that occurred between 30 and 280 miles beneath the Earth's surface in the Pacific Plate as it descended into the Tonga Trench were surprised to find a zone of intense earthquake activity in the downgoing slab. The pattern of the activity along the slab provided strong evidence that the earthquakes are sparked by the release of water at depth.

Where’s the Center of North America? UB Geographer’s New Method Finds a New Answer

Where is the geographic center of a state, country or a continent? It’s a question fraught with uncertainty. Do you include water in your calculation? What happens when the shoreline shifts? But to University at Buffalo geographer Peter Rogerson, the challenge of finding a middle doesn’t mean you shouldn’t try.

Fossil Fuel Formation: Key to Atmosphere’s Oxygen?

blackshalecroplg_LK.jpg

For the development of animals, nothing — with the exception of DNA — may be more important than oxygen in the atmosphere. A study now online in the February issue of Earth and Planetary Science Letters links the rise in oxygen to a rapid increase in the burial of sediment containing large amounts of carbon-rich organic matter.

A Tectonic Shift in Predicting Earthquakes, Volcanic Hazards

A recent study by the University of Delaware's Jessica Warren and colleagues at two other universities provides a new data set that scientists can use to define a tectonic plate and predict future earthquake and volcanic hazards, where they might occur and how deep the devastation might be.
