Ocean Acidification

Arctic Cruise 2011

Proposed track for the August 2011 cruise.
Track of the August 2011 cruise. [larger version]

On August 15, 2011, a team of scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center and the University of South Florida (USF) boarded the USCGC Healy in Barrow, Alaska, for a seven-week journey in the Arctic Ocean. The team measured baseline seawater chemistry of the Arctic Ocean in order to improve understanding of ocean acidification in polar regions. The scientists worked side-by-side with other scientists aboard who were gathering data about the Extended Continental Shelf (ECS, Law of the Sea), the primary mission of the Healy cruise.

USGS Senior Scientist Lisa Robbins and her team members on board the ice cutter Healy took seawater samples using:

These data, along with the underway data the Healy provides (temperature, salinity, dissolved oxygen, fluorescence, CDOM, depth, wind speed, etc.), allow scientists to obtain a better understanding of the regional ocean chemistry. The cruise track for the 2011 expedition is seen on the right.
