Tide gauges capture tremor episodes in cascadian subduction zone

Fri, 15 Feb 2019 09:29:22 EST ~ Hourly water level records collected from tide gauges can be used to measure land uplift caused by episodic tremor and slip of slow earthquakes in the Cascadia Subduction Zone, according to a new report. Find out more...

Massive Bolivian earthquake reveals mountains 660 kilometers below our feet

Thu, 14 Feb 2019 15:31:25 EST ~ Geophysicists used data from an enormous earthquake in Bolivia to find mountains at the base of the mantle's transition zone, located 660 kilometers below our feet. Their statistical model didn't allow for precise height measurements, but these mountains may be bigger than anything on the surface of the Earth. The researchers also examined the top of the transition zone (410 km down) and did not find similar roughness. Find out more...

The smallest skeletons in the marine world observed in 3D by synchrotron techniques

Thu, 14 Feb 2019 11:55:38 EST ~ Coccolithophores are microscopic marine algae that use carbon dioxide to grow and release carbon dioxide when they create their miniature calcite shells. Scientists have revealed the nano-level 3D structure of their calcite shells, providing new perspectives for assessment of the role of these tiny microorganisms in the global carbon cycle. Find out more...

Undersea gases could superheat the planet

Wed, 13 Feb 2019 09:08:12 EST ~ Geologic carbon and hydrate reservoirs in the ocean pose a climate threat beyond humanmade greenhouse gases. Find out more...

Antarctic ice shelves buckle under weight of meltwater lakes

Wed, 13 Feb 2019 08:16:50 EST ~ The filling and draining of meltwater lakes has been found to cause a floating Antarctic ice shelf to flex, potentially threatening its stability. Find out more...

Wave device could deliver clean energy to thousands of homes

Tue, 12 Feb 2019 19:08:52 EST ~ A device that could convert wave energy into electricity has been demonstrated in scaled trials. Find out more...

New deep sea animal discoveries warrant expanded protections in Costa Rican waters

Mon, 11 Feb 2019 18:29:01 EST ~ Scientists surveyed deep-sea seamounts outside Isla del Coco UNESCO World Heritage site revealing coral communities with surprising diversity. Find out more...

NASA finds possible second impact crater under Greenland ice

Mon, 11 Feb 2019 18:28:36 EST ~ A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland. Find out more...

Arctic sea ice loss in the past linked to abrupt climate events

Mon, 11 Feb 2019 16:40:33 EST ~ A new study on ice cores shows that reductions in sea ice in the Arctic in the period between 30-100,000 years ago led to major climate events. During this period, Greenland temperatures rose by as much as 16 degrees Celsius. Find out more...

Marine scientists find toxic bacteria on microplastics retrieved from tropical waters

Mon, 11 Feb 2019 11:03:48 EST ~ A team of marine scientists had uncovered toxic bacteria living on the surfaces of microplastics (which are pieces of plastic smaller than 5 millimeters in size) collected from the coastal areas of Singapore. These bacteria are capable of causing coral bleaching, and triggering wound infections in humans. The team also discovered a diversity of bacteria, including useful organisms - such as those that can degrade marine pollutants like hydrocarbons - in the plastic waste. Find out more...
