I am conducting research and am looking to track the monthly TEU volumes for various U.S. ports, including the Seattle-Tacoma NW Seaport Alliance. I did find a pdf on your website that includes a great deal of information on the monthly TEU volumes, however I was hoping to see the total full and total empty imports/exports. Only international imports/exports appear to be broken up into full vs. empty, and I am hoping there is a way to access that information in total, not just international volume. Please let me know if there if you can provide this data, or if you have an alternative database where the data can be accessed. Thank you; I appreciate your time.
