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 column stations were sampled over 100 days at sea along the section, making a variety of physical, chemical and biological measurements.  The data collected on this expedition will be compared with earlier data sets from previous decades to detect changes in ocean properties.
