About the Gordon Gunter
The NOAA Ship Gordon Gunter, commissioned on August 28, 1998 was originally the U.S. Naval Ship RELENTLESS. Beginning in March 1998, the ship was refitted to contain modern navigational electronics, oceanographic winches, sensors, sampling equipment, and a custom-designed marine mammal observation and survey station. The Gordon Gunter operates primarily in the Gulf of Mexico, Atlantic and Caribbean waters. For more information on the Gordon Gunter, follow the link to its homepage.

About this Web Site
In 2008, the Global Carbon Group at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) installed an underway system to measure surface pCO2 on the Gordon Gunter. This web site provides access to this data. The data are organized by year and by cruise. For each cruise, a graph showing the pCO2 values plotted on the cruise track is shown. Next to each graph are links to the comma-delimited data file and associated Readme text file. To download a particular file, select the year from the drop-down list box and click on GO. Select a cruise, right-click on the link to its data file and select the download option. The same procedure can be applied to download the Readme files. The Realtime Display link consists of plots of the data as they are received and is mainly used for troubleshooting. The realtime data has not been quality controlled and should not be used for scientific purposes. The first two Realtime Display plots represent raw (unprocessed) xCO2 data as a function of time and location. Other links in the menu bar on the left provide contact information and return access to the AOML GCC homepage.
