The Submarine Ring of Fire ’14 cruise is completed and PMEL scientists are back in the lab analyzing the data. While underway, 19 short videos were created by Saskia Madlener with music by Charlie Brooks. Take a look at the videos to get a sense of what life on the ship was like and how the scientists dealt with successes and challenges at sea. Despite problematic weather, the scientists were able to get biological, chemical, geological and acoustic data over the duration of the cruise, using hydrographic instruments and the remotely operated vehicle Jason.

Along with increasing sea levels, melting glaciers are putting something else into the world’s oceans -- a huge load of organic carbon that has the potential to change marine chemistry and ecosystems, says a newly published study by a team of mostly Alaska scientists.
The waves that most of us are familiar with are the waves at the beach—waves that endlessly curl and crash on the shore. But the ocean and atmosphere also have what are called “planetary waves”—waves of immense scale. Kelvin waves are a kind of planetary wave.
In December, Pure and Applied Geophysics (PAGEOPH) published the topical issue, Tsunamis in the Pacific Ocean: 2011-2012, which contains 21 new papers discussing tsunami events that occurred in this two-year span. PMEL scientists contributed three of the papers to this issue.
Bernard et al. report on a small tsunami produced by a Mw 7.3 earthquake offshore of Japan, adjacent to the source region for the 2011 Tohoku event. They present deep-water... more
