Stellwagen usage notes

All the data collected by the sediment transport group over the years has been released in the on-line database of oceanographic time-series data at https://stellwagen.er.usgs.gov/.

The full documentation about stellwagen is available at http://dx.doi.org/10.3133/ofr20071194. The Database Access sections have useful related information.

Some notes about how to delve into the data holdings, based on this use case "which meteorological sensors were used on each of the buoys in the Fire Island 2014 experiment?" are shown below. Note: the images display data from 2 different buoys 985 and 1001, so the serial numbers should be different!

Method 1: Use ncBrowse

ncBrowse is a program written by PMEL (http://www.epic.noaa.gov/java/ncBrowse/) of display time-series data that follows the EPIC convention (ours does).

  • get the file you need from stellwagen by
    • clicking on "Experiment list" in the menu tab at the top of the screen
    • select "Fire Island 2014"
    • click on "Catalog of data" in the top right of the page. A new page will be displayed that shows the files available, and some metadata about them.
    • click on 9851met-a.nc to download it.
  • open the file in ncBrowse (right click on the name then choose open with "launchanywhere")
  • click on "view"
  • click on "as table"
  • click on "expand all" at the bottom of the newly displayed window.
  • scroll down to examine the structure and contents of the file. The model and serial number will be under the variable name as shown

You can also click on the variable names in the white part of the original window to plot the data in each variable.

Method 2- using OPeNDAP in the THREDDS server

  • go to the experiment page as described in method 1
  • click on "data access via THREDDS (EPIC)"
  • Click on the file name you want to examine
  • click the first option (OPeNDAP) in the list, and a new page with a lot of information about the file will be displayed
  • scroll in each variable to see the model and serial numbers (shown below)
