New research suggests that continually monitoring gravity changes near active volcanoes could provide insights into volcanic activity.
Pacific Ocean
An Ancient Sea Once Separated the Pacific and Indian Oceans
Seafloor under the hypothesized East Asian Sea vanished 10 million years ago as surrounding plates swallowed it up, according to new reconstructions of plate tectonics in the Philippine Sea region.
In the Eastern Pacific Ocean, the "Blob" Overshadows El Niño
Underwater gliders and ocean modeling reveal unexpectedly weak El Niño effects on a major West Coast current.
Closing the Pacific Rainfall Data Void
A new climatology tool uses satellite data to map precipitation in a data-sparse region of the Pacific Ocean.
Shift in Pacific Sea Level Trends Will Affect the West Coast
The first study on the shift toward higher sea levels in the eastern Pacific Ocean over the past 5 years indicates it will continue, leading to much higher seas on the western coasts of the Americas.
Japan's Volcanic History, Hidden Under the Sea
Scientists investigate marine tephra layers for clues to Japan's volcanic past.
Ocean Floor Networks Capture Low-Frequency Earthquake Event
Last August, stations on a newly deployed permanent ocean floor observation network recorded rarely seen, very low frequency signals from shallow earthquakes.
Streamlining Rapid Tsunami Forecasting
With enough sensors, traditional forecasting methods could be replaced by models continuously updated with real-time wave data.
What Does the Pacific Arctic's New Normal Mean for Marine Life?
Climate change has reconfigured Arctic ecosystems. A 5-year project focuses on the relationships among oceanographic conditions and the animals and other life-forms in this region.
Understanding the Distribution of Juvenile Jumbo Squid
An expanding zone of shallow, oxygen-depleted water in the eastern tropical Pacific Ocean may be vertically restricting the habitat of this important source of food, according to a recent study.
