Dec. 11 mini-symposium in Washington, D.C. celebrates 1 million ocean profiling milestone of the international Argo float network

The Argo program, a global array of more than 3,000 autonomous ocean-monitoring floats, has collected its one millionth profile of ocean salinity and temperature-a critical milestone in ocean observing science. To celebrate, the National Oceanographic Partnership Program (NOPP) invites media to an Argo mini-symposium which includes speakers from U.S. federal agencies and international researchers that are involved in the program and support its continued growth.

To put this achievement into context, since the 1890s, oceanographers have collected only about 500,000 profiles in the upper 1,000 meters and only about 200,000 to 2,000 meters of the ocean's surface. It took Argo floats a dozen years to reach 1 million profiles at these depths, and, but will only take eight years to collect the next million profiles. The use of this sustained dataset can improve projections of sea level rise, better our understanding of climate variability, and offer insights into ocean heat circulation.

NOAA is committed to maintaining one-half of the worldwide Argo network by supporting the U.S. component of the international program. The Argo Program was originally funded through NOPP in 1999 and continued to be implemented through NOPP until 2011. Today, Argo is funded as tasks under cooperative agreements with three academic institutions, along with programs within NOAA. To learn more, visit

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter and our other social media channels.
