About the M/V Skogafoss
In March 2014, the Ocean Carbon Group (OCC) at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) installed an automated system to measure surface pCO2 on the Volunteer Observing Ship M/V Skogafoss. The M/V Skogafoss affords AOML's OCC scientists an opportunity to gather data in the North Atlantic Ocean. In addition, the ship regularly repeats the same cruise track thus allowing the instruments to monitor small changes in the ocean and atmosphere. Eventually, a long series of high quality observations will be available that will provide new insights on weekly, monthly, seasonal, and longer time cycles. Every 4 hours, the instrument takes at least 5 air measurements and 100 water measurements while the ship is underway. Each 4-week cruise track begins and ends in Portland, Maine. Every day via Iridium satellite communications, the data is sent to AOML where it is processed, and the final data is posted to the Skogafoss web site. Files are arranged by year using the cruise designation skoYYYYMMDD.csv where YYYY is the year, MM the month and DD the date.

About this Web Site
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 xml 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 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.
