Project Summary
      
From August 4 to September 6, 2010, a joint operation between the United 
States and Canadian governments occurred to collect seismic-reflection, 
multibeam bathymetric, and high-resolution chirp data aboard the Canadian 
Coast Guard Ship (CCGS) Louis S. St-Laurent and U.S. Coast Guard Cutter 
(USCGC) Healy icebreakers. These operations were part of the U.S. 
interagency Extended Continental Shelf Project to determine the limits of 
the continental shelf in the Arctic. The Chief Scientist aboard the USCGC 
Healy was USGS scientist Brian Edwards. On a non-interference basis, a 
USGS Ocean Acidification team participated on the Healy to collect 
baseline water data in the Arctic. The USGS Ocean Acidification team, led 
by Lisa Robbins, included both shipboard and home-based team members. A 
number of hypotheses were tested and questions asked associated with 
ocean acidification, including: 
* How do pCO2 fluxes compare within the Arctic Ocean's Canada Basin?
* What is the saturation state for different parts of the basin?
* How does saturation state compare to other regions? If temperature was 
not a factor, how is the saturation state of the Arctic Ocean responding 
to increased atmospheric CO2?
* What is the buffering capacity of the water (Revelle Factor)?
* What kind of variability does the carbon demonstrate in the Arctic 
(near shore versus offshore)? 
      During the cruise, underway continuous and discrete water samples 
were collected and water samples were collected at stations to document 
the carbonate chemistry of the Arctic waters and quantify the saturation 
state of seawater with respect to calcium carbonate. These data are 
critical for testing existing models for which little baseline data is 
available for validation of model results.
