PACKAGE DESCRIPTION: This dataset includes surface chemical, meteorological, physical data collected from Saildrone TPOS_2017_SD1006 in the North and Tropical Pacific Ocean from 2017-09-02 to 2018-05-18. These data include mole fraction of CO2 in air in equilibrium with the seawater at sea surface temperature and measured humidity, mole fraction of CO2 in air from airblock, 4 feet above the sea surface at measured humidity, barometric pressure, LICOR temperature and pressure, oxygen percent saturation, partial pressure of carbon dioxide in water, partial pressure of carbon dioxide in atmosphere, difference of the partial pressure of CO2 in seawater and air (pCO2 SW - pCO2 Air) and pH on total scale. The Autonomous Surface Vehicle CO2 (ASVCO2) instruments used to collect these data include Bubble type equilibrator for autonomous carbon dioxide (CO2) measurement, Carbon dioxide (CO2) gas analyzer, Humidity Sensor, and oxygen meter.

Detailed sampling and analyzing information: |
At the beginning of each sample, the instrument self-calibrates using a zero and high standard. The zero standard is generated by cycling a small amount of air through a soda lime chamber. The high standard is from a cylinder of calibrated standard reference gas, 396.21 umol/mol, from ESRL. ESRL standards are traceable to WMO x93 scale with a stated reproducibility of 0.06 micromole/mole. For more information on estimates of accuracy and precision of the MAPCO2 system, see Sutton et al. 2014. |

%O2 |
Abbreviation: |
%O2 |
Unit: |
The percent oxygen of the surface seawater divided by the percent oxygen of the atmosphere at 4 feet above the sea surface. Disclaimer: The oxygen measurement is made in the equilibrated air. We have found that the oxygen does not come to complete equilibrium so any rapid changes in oxygen do not get properly captured using this system. Therefore, we tend to use the oxygen data only as a qualitative sense of the biology. It is not a quantitative measure. |
