This dataset includes triple oxygen isotopes (δ17O and δ18O), a tracer of gross primary production; oxygen/argon dissolved gas ratios, a tracer of net community production or carbon export; temperature and salinity. Samples were collected during transects across the Pacific Ocean from Hong Kong to Long Beach, CA on commercial container ships starting in 2008.
