Sedimentation

Over 4.5 billion years, volcanoes, asteroids, and climate change have wiped out millions of species.

Not all critical minerals need to come from digging up the earth.

THIRUVANANTHAPURAM, India, Feb 25 (IPS) - Ibrahim Basheer plunges into the sea and disappears. He remains gone for a couple of minutes before resurfacing for a deep breath of air, repeating this for the next half an hour. When he finally climbs aboard his boat, the net sack around his neck is filled with mussels—his catch for that diving trip. He rests for a short while before diving into the sea again—needing one…

In Puerto Rico and elsewhere, researchers are attempting to restore coral reefs and make corals more resilient to ocean heat — with some recent success.

The amount of contaminated water laced with raw sewage that is flowing across the U.S.-Mexico border into San Diego County exceeded 44 billion gallons in 2023, the most on record in the last quarter-century.

The important role of the Southern Ocean in global biological processes and the carbon cycle has been confirmed anew by a study published in Science that, for the first time based on field evidence, reveals the underappreciated role of inorganic zinc (Zn) particles in these cycles.

The fjords on Sweden's west coast act as effective carbon traps regardless of whether the bottom water is oxygen-rich or not. This is the conclusion of a new study by researchers from the University of Gothenburg.

Archaeologists have discovered what may be Europe's oldest human-made megastructure, submerged below the Baltic Sea and dubbed the Blinkerwall

In southern Germany just north of the Danube, there lies a large circular depression between the hilly surroundings: the Nördlinger Ries. Almost 15 million years ago, an asteroid struck this spot. Today, the impact crater is one of the most useful analogs for asteroid craters on early Mars.

Are you hungry for some nitro-scrambled egg-and-bacon ice cream? Did you want a little fried mayo on that sandwich? Molecular gastronomy has cast cooking in a new light and created some seemingly bizarre, but shockingly delicious dishes.

Global warming is not solely a modern-day occurrence but has been a prominent feature of Earth's geological history for millennia. One such event occurred approximately 40 million years ago, lasting ~400,000 years, known as the Middle Eocene Climatic Optimum (MECO).

Amazonian lakes sequester carbon dioxide at a rate 39% higher than the rainforest itself. This is according to a 2022 study by researchers from Brazil, Australia, the U.S., France, Portugal, the U.K. and Sweden. They found that these bodies of water trap 113.5 grams of carbon per square meter per year in their sediment, while […]

Recently, the journal Science China Earth Sciences published research by Professor Hongwei Kuang, Dr. Nan Peng and Professor Yongqing Liu from the Institute of Geology, Chinese Academy of Geological Sciences.

Carbon sequestration is the process of capturing atmospheric CO2 — the most commonly produced greenhouse gas — and storing it in the Earth.

Radiation in water from Fukushima will be diluted to almost background levels, but some researchers are not sure this will be sufficient to mitigate the risks

Water is an essential and indispensable component of humanity's everyday existence. As the global population grows and the climate warms, so does the water demand.

Varda's satellite is currently operating in orbit after a successful launch on June 12th aboard SpaceX's Falcon 9 rocket

There are benefits of studying certain biological processes under microgravity, but whether those advantages outweigh the costs of getting experiments off Earth remains to be seen.

Cratons are pieces of ancient continents that formed several billions of years ago. Their study provides a window as to how processes within and on the surface of Earth operated in the past. Cratons preserve relics of our young Earth as they host a variety of rock assemblages such as greenstones and granites. Greenstones are rock assemblages that are primarily composed of sub-marine volcanic rocks with minor…

Leda Kobziar and other pyroaerobiologists find life up in smoke. Literally.
