Interactive Graphs and Tables

The NBIC has been receiving ballast water reporting forms from commercial vessels that arrive to U.S. ports from overseas since July 1, 1999. Federal law ( National Invasive Species Act of 1996, P.L. 104-332) mandates that all such arriving ships complete and submit a ballast water information report to NBIC. Ballast Water Management Report forms are available in a number of formats. From these data, the NBIC has created a series of interactive charts and tables that summarize ballast water discharge and management, and ship arrivals, by coastal region and by state over time. In addition, the NBIC has also developed graphs on invasion biology and vectors over time. To access these graphs, click on each of the categories below.

Note: All data available in graphs and tables extend through the last complete month and are refreshed monthly. As ballast water management reports may be amended, corrected or changed during quality control processes, particularly within the 20 days from arrival date for the last complete month, this will result in updates that will register when the data are next refreshed.  All data are subject to change and use of any of the NBIC data implies agreement with the NBIC Data Use Agreement policy. Cite our data.
