Low-Oxygen 'Dead Zones' in North Pacific Linked to Past Ocean-Warming Events

Nov. 18, 2015 — A new study has found a link between abrupt ocean warming at the end of the last ice age and the sudden onset of low-oxygen, or hypoxic conditions that led to vast marine dead ... read more

Nov. 18, 2015 — The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction ... read more

Nov. 18, 2015 — A year ago, researchers discovered that fat helps coral survive heat stress over the short term -- and now it seems that fat helps coral survive over the long term, too. The study offers important ... read more

Study Links Deep-Time Dust With Major Impacts on Carbon Cycling

Nov. 17, 2015 — A new study links vast amounts of iron-rich dust deposits from the late Paleozoic period of 300 million years ago with implications for major ecosystem fertilization and a massive drawdown of ... read more

Nov. 16, 2015 — Seismologists studying the 2011 Chile earthquake have discovered a previously undetected earthquake that took place seconds after the initial rupture. This newly discovered phenomena, which they ... read more

Nov. 16, 2015 — The first data-driven estimate of the Earth's total supply of groundwater shows that less than six per cent of groundwater in the upper two kilometers of the Earth's landmass is renewable ... read more

Nov. 16, 2015 — Ancient climates on Earth may have been more sensitive to carbon dioxide than was previously thought, according to new research. Scientists examined nahcolite crystals found in Colorado's Green ... read more

Nov. 13, 2015 — A shortage of a rare mineral could spur global market instabilities, according to a new analysis of international commodity trade ... read more

New Research Shows La Niña Is Not Helping Hawai'i's Rainfall, Groundwater

Nov. 12, 2015 — Historically when El Niño events occur, Hawai'i has experienced nearly six months of drought, from November to April. Conversely, during La Niña events rainfall has been greater than normal - ... read more

Nov. 12, 2015 — According to new research, a mass extinction 359 million years ago known as the Hangenberg event triggered a drastic and lasting transformation of Earth's vertebrate ... read more

Oceans, Ocean Activism, Deserve Broader Role in Climate Change Discussions

Nov. 12, 2015 — Researchers argue that both ocean scientists and world leaders should pay more attention to how communities are experiencing, adapting to and even influencing changes in the world's ... read more

Nov. 12, 2015 — A glacier in northeast Greenland that holds enough water to raise global sea levels by more than 18 inches has come unmoored from a stabilizing sill and is crumbling into the North Atlantic Ocean. ... read more

Increased Deforestation Could Substantially Reduce Amazon Basin Rainfall

Nov. 12, 2015 — Continued deforestation of the Amazon rainforest could diminish the amount of rain that falls in the Amazon River basin, finds a new study. These declines in rainfall could potentially alter the ... read more

Nov. 12, 2015 — Gradual melting of winter snow helps feed water to farms, cities and ecosystems across much of the world, but this resource may soon be critically imperiled. In a new study, scientists have ... read more

Nov. 11, 2015 — It is common knowledge that the Earth's rigid upper layer called lithosphere is composed of moving plates. But just what mechanism first set plate tectonics into motion still remains a mystery. ... read more

Nov. 11, 2015 — The sensitivity of marine communities to ocean warming rather than rising ocean temperatures will have strong short-term impacts on biodiversity changes associated with global warming, according to ... read more

Nov. 11, 2015 — A research team is using the Titan supercomputer to develop physics-based earthquake simulations to better understand earthquake systems, including the potential seismic hazards from known faults and ... read more

Idea of Slow Climate Change in Earth's Past Misleading

Nov. 11, 2015 — Climate change is progressing rapidly. It is not the first time in our planet's history that temperatures have been rising, but it is happening much faster now than it ever has before. Or is it? ... read more

Dust, Iron, Life: How Atmospheric Dust Prepped Earth for Life

Nov. 10, 2015 — Dust begets life, and Earth's atmosphere 300 million years ago was perhaps the dustiest of all time, with large consequences for carbon cycling and the climate system. In a new article ... read more

Nov. 10, 2015 — A new study identifies a set of features common to all ocean ecosystems that provide a visual diagnosis of the health of the underwater environment coastal communities rely on. Together, the features ... read more
