USGS Data Series 741

Who They Are

The U.S. Geological Survey (USGS) is a scientific agency that is part of the U.S. Government’s Department of Interior. Its scientists study geology and earth sciences, as well as the natural hazards that threaten it. While contracted to the USGS, I was a part of a team that published a report on carbon data in the Arctic Ocean.

What They Needed

  • A simple way to analyze and display the complex three-dimensional data both on the website and on a poster.
  • A version of the report that could be distributed both on the web and on CD

The Solution

For the data, we had several large datasets containing up to 354,000 three-dimensional ocean chemistry measurements. We needed to be able to display this data on a map, but Excel could not plot the data on a map, and GIS could only plot two of the three dimensions on a map.

For the website, the USGS provided a template that I customized using HTML and CSS to create a foundation for the website to be built on. I posted the cruise data, XML metadata, and the GIS shapefiles I had created to the website, and the lead scientists provided me with the text and the rest of the content.

The End Result

I saved over 1 month of data analysis by writing a Mathematica script that consolidated over 50 two-dimensional figures into 4 three-dimensional figures that were plotted on a three-dimensional bathymetric grid of the ocean floor, allowing the entire dataset to be displayed on our poster at the 2010 American Geophysical Union Fall Meeting. The report was published in 2013.
