IAEA Affirms Japan’s Fukushima-Related Radioactivity Monitoring
Laboratories outside Japan have validated the results. Marine radioactivity levels from the nuclear disaster have fallen, but questions remain years after the meltdown.
An 1888 Volcanic Collapse Becomes a Benchmark for Tsunami Models
When volcanic mountains slide into the sea, they trigger tsunamis. How big are these waves, and how far away can they do damage? Ritter Island provides some answers.
Is the Lower Crust Convecting Beneath Mid-Ocean Ridges?
The first attempt to couple models of hydrothermal circulation and magmatic convection along fast-spreading ridges may explain the spacing of hydrothermal vent fields along the East Pacific Rise.
Powerful Pacific Forces Disrupt the California Current
Scientists create a 66-year data record to shed light on the role of El Niño in the California Current System’s shifting temperatures.
Auroras May Explain an Anomaly in Earth’s Ionosphere
A new study finds that the ionospheric anomaly over the Weddell Sea is likely influenced by proximity to auroral energy input, rather than by tilting magnetic fields.
Sediment Cores Reveal Ocean Current’s Past Life
East Asia’s Black Current may have rerouted in the past 10,000 years or so.
Mesmerized by Gracefully Gliding Albatrosses
Despite avian distractions and dreadful weather, a research cruise to map the seafloor off Alaska revealed new insights into the Queen Charlotte Fault.
Probing the Power of Pacific Supertyphoons
Despite higher than normal surface temperatures and heat contents of ocean waters where the storms developed, evidence is lacking that global warming is revving them up.
New Volcanic Island Unveils Explosive Past
A recent volcanic eruption near Tonga in the southwest Pacific created a new island, giving scientists a rare opportunity to explore the volcanic record of this remote region.
