Earthquake depth impacts potential tsunami threat
Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis.

Meltwater influences ecosystems in the Arctic Ocean
In the summer months, sea ice from the Arctic drifts through Fram Strait into the Atlantic. Thanks to meltwater, a stable layer forms around the drifting ice atop the salty seawater, producing significant effects on biological ...

Environmental DNA is a reliable way to learn about migration from the ocean twilight zone
The mid-ocean "twilight zone" holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult. Many inhabitants ...

Ocean microplastics: First global view shows seasonal changes and sources
An estimated 8 million tons of plastic trash enters the ocean each year, and most of it is battered by sun and waves into microplastics—tiny flecks that can ride currents hundreds or thousands of miles from their point ...

Small 'snowflakes' in the sea play a big role
In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called "marine snow." Marine snow does not only look like real snow but also behaves similarly: Large flakes ...

Study reveals uncertainty in how much carbon the ocean absorbs over time
The ocean's "biological pump" describes the many marine processes that work to take up carbon dioxide from the atmosphere and transport it deep into the ocean, where it can remain sequestered for centuries. This ocean pump ...

Data models point to a potentially diverse metabolic menu at Enceladus
Using data from NASA's Cassini spacecraft, scientists at Southwest Research Institute (SwRI) modeled chemical processes in the subsurface ocean of Saturn's moon Enceladus. The studies indicate the possibility that a varied ...
