aNitrate bottle measurements from the same CTD cast were interpolated to the depths of the ?13C							
bottle measuremts.
"bSampling location: 42.105°N, 125.837°W."
"cIdentical depths at the same site indicate duplicate ?13C measurements, the same nitrate measurement"
 is listed for each ?13C replicate.
