In support of NOAA’s new Ocean Acidification Program, scientists from PMEL's carbon group will begin a 22-day cruise on August 11 along the Pacific west coast to survey ocean acidification (OA) conditions and study the relationship between OA and the seasonal development of hypoxic conditions on the continental shelf. Funded by the NOAA Ocean Acidification and Global Carbon Cycle Programs, the cruise will sample at approximately 96 stations offshore from Washington to California. In conjunction with the cruise, repeat glider transects will be conducted and testing of new wave gliders will also occur to provide a large-scale picture of OA along the U.S. west coast.
PMEL and University of Washington scientists will help campers turn into oceanographers at the 9th annual NOAA Science Camp in Seattle, Washington the weeks of July 18th and 25th. Middle school campers will get to experience what it is like to be an oceanographer by using instruments to measure physical properties of the water and atmosphere as well as getting the chance to see a working buoy in the water and learn how PMEL uses buoys to gather data around the world.
NOAA Science Camp is sponsored by Washington Sea Grant. Check out their web page for a video and more information.
Scientists and engineers at PMEL recently returned from an expedition in the Arctic where they launched two small, new, remotely-operated, unmanned aircraft to measure black soot. The soot is produced by burning diesel fuel, agricultural fires, forest fires, and wood-burning stoves, and is transported by winds to the Arctic, where it darkens the surface of snow and ice, enhancing melting and solar warming.
PMEL staff are aboard two international vessels to recover and deploy moorings in the Indian Ocean as part of the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA) project. RAMA was initiated in 2004 to collect key oceanographic and meteorological data from the poorly observed Indian Ocean.
NOAA has updated the Arctic Future website to reflect recent observations and add results in the Arctic Council 2011 Snow, Water, Ice and Permafrost in the Arctic assessment. Other topics include: satellites show the Arctic losing summer sea ice for the past 30 years, an increased linkage between the Arctic and mid-latitudes, and glacier melt contributing to sea level rise.

Scientists from PMEL’s Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI) group set sail on April 30 for the first major cruise of Gulf of Alaska Integrated Ecosystem Research Program (GOA-IERP). Led by PMEL's Dr. Nancy Kachel, EcoFOCI and GOA-IERP will look at oceanographic and climate influences, and relationships between trophic levels in a changing ecosystem and will include zooplankton sampling, hydrographic measurements, water and iron sampling.
For more information on this expedition please visit the EcoFOCI cruise website.
PMEL scientists, Dr. Tim Bates and Dr. Patricia Quinn, will lead the US component of the Coordinated Investigation of Climate-Cryosphere Interactions (CICCI) project based out of Svalbard, Norway during the month of April. PMEL will fly two Unmanned Aerial Systems (UAS) equipped with sensors to measure aerosol properties to help understand the processes controlling the distribution of black carbon in the Arctic atmosphere.
Using data from two hydrophones, Dr. Bob Dziak and his acoustics team at PMEL and Oregon State University captured the sounds of the March 11 Mw 9.0 earthquake that shook Japan and sent a tsunami wave across the Pacific Ocean. The hydrophones recorded the seismic and acoustic arrivals of the earthquake, known as P- and T-waves respectively.
Research models developed at PMEL’s NOAA Center for Tsunami Research and installed at NOAA Tsunami Warning Centers accurately predicted the wave arrival time within 15 minutes for Hawaii, Alaska, and the U.S. West Coast during the Honshu tsunami event on March 11. The 9.0 magnitude earthquake was detected by a Deep-Ocean Assessment and Reporting of Tsunamis (DART®) 3 minutes after the earthquake and the tsunami was measured 25 minutes later.
PMEL recently launched its own YouTube channel where you will find our stories and research come to life with videos, photos, and animations often narrated by the scientists that do the research. On the PMEL YouTube channel you can learn how a tsunami forecast is generated, listen to the sounds of the Arctic, watch an animation on the latest buoy technology, plus much more.
