In a paper published recently in Nature Geoscience PMEL Atmospheric Chemistry group, led by Dr. Patricia Quinn, and others show that the organic carbon content of sea spray aerosol (produced by breaking waves on the ocean surface) was similar in all...

From August 2013 to February 2014, PMEL scientists and technicians from multiple groups participated in an Atlantic Ocean survey of the A16 line from 63°N near Iceland to 63°S near Chile on the NOAA Ship Ronald H. Brown. In total, 258 full water...

For the first time, in a research article published January 19 in Nature Climate Change, PMEL's Dr. Michael McPhaden and a team of international scientists provide robust and convincing evidence that greenhouse warming will double the chance of...

PMEL’s Dr. James Overland explains why the eastern United States is experiencing frigid temperatures in early January 2014 on the Arctic web site's new Polar Vortex page. He describes how in the last five years we have seen the jet stream transform...

PMEL's Dr. James Overland is one of three editors of the 2013 Arctic Report Card, released December 12 at the American Geophysical Union's fall meeting. Authored by 147 scientists from 14 countries, this year's report concluded that while long-term...

PMEL successfully deployed the first carbon dioxide flux and ocean acidification mooring in the Northern Indian Ocean on November 23. The Bay of Bengal Ocean Acidification (BOBOA) mooring will help us understand the large intraseasonal, seasonal and...

A two-month long oceanographic expedition, led by PMEL's Dr. John Bullister and AOML's Dr. Molly Baringer, along the A16N line in the Atlantic Ocean was recently completed on NOAA ship Ronald H. Brown. About 50 scientists, from 6 countries made a...

The tropical cyclone Pabuk passed NOAA's Kuroshio Extension Observatory (KEO) mooring on September 26, 2013, followed by Wipha on October 15th, and Francisco on October 26th. Measurements collected during Typhoon Pabuk will be compared with...

The 2013 North Pole web cams were recovered on September 20, marking the end of another successful season monitoring Arctic conditions. The web cams are part of the North Pole Environmental Observatory, tracking snow cover, weather conditions, and...

PMEL scientists Drs. Christopher Sabine and Gregory Johnson participated in the final government approval meeting for the Intergovernmental Panel on Climate Change Working Group I Fifth Assessment Report's Summary for Policymakers (SPM) in Stockholm...

PMEL engineers deployed a Deep-ocean Assessment and Reporting of Tsunamis (DART®) 4th generation monitoring system off the coast of Oregon last week. This system is an enhanced version of the DART®-ETD (Easy to Deploy) technology developed at NOAA...

On Monday, September 9, the launch of the Wendy Schmidt Ocean Health XPrize was announced. XPrize partnered with NOAA and PMEL to help design the XPrize, a $2M competition for the development of two pH sensors to improve our understanding of ocean...

Since it began maintaining a mooring station at the Papa site in the Gulf of Alaska in 2007, PMEL's Ocean Climate Station program has been providing climate and weather observations. In July 2013, Papa became central to the National Science...

The American Meteorological Society released its 2012 State of the Climate report in August that provides annual updates on global climate indicators compiled by 384 scientists from 52 countries. PMEL scientists contributed to 6 articles including...

Scientists from PMEL left for a month-long research cruise in the beginning of August to better understand how the marine ecosystem is responding to changing ocean chemistry along the U.S. West Coast. Scientists aboard the NOAA Ship Fairweather will...

PMEL and JISAO scientists are tracking Arctic sea ice conditions with animations of images from web cams deployed in springtime at the North Pole by the North Pole Environmental Observatory. Images received on July 15 (seen left) reveal widespread...
