Summary
Abstract: This package documents carbonate data obtained during two NOAA CO2
Dynamics Cruises and the NORPAX Hawaii-Tahiti Shuttle Experiment. One
data source was NOAA/s CO2 Dynamics Cruise of the eastern North
Pacific aboard the R/V MILLER FREEMAN. The ship departed Kodiak,
Alaska, on June 14, 1981 and arrived at Hilo, Hawaii, on July 4 after
occupying nine stations along the 150 degree West vertical transect.
After reaching the southernmost point of the cruise track (8 degrees
North), the R/V MILLER FREEMAN occupied seven stations while returning
to Seattle, Washington. Data, including alkalinity, calcium, and pH,
are provided for all sixteen stations.

The second source of data, NOAA's CO2 Dynamics Cruise in the western North
Pacific aboard the R/V DISCOVERER, departed Kwajalein, Alaska, on May 27, 1982
and arrived at Adak, Alaska, on June 29, 1982. During the cruise, ten stations
were occupied with all stations located near the 165 degree East vertical
transect. Total alkalinity and pH measurements were determined at 25 degrees
Celsius using a Radiometer TTT61 Digital Titrator and a combination electrode,
respectively.

For the NORPAX Hawaii-Tahiti Shuttle Experiment, samples were collected during
Legs 3 (April, 1979) and 13 (March-April, 1980). Greater details about the
cruise tracks, the precision and calibration of the experimental techniques,
and discussion of the data are provided in NDP-029 by CDIAC.

Based on these data, Chen et al., (1986) concluded that the North Pacific Ocean
contains 14.7 x 10,15th grams excess carbon and that the deep water of the
eastern North Pacific is older than that of the western North Pacific. They
also estimated that about a 25% increase in total inorganic CO2 of deep water,
after leaving the Southern Ocean surface, is contributed by inorganic CaCO3
dissolution.
