Research into Marine Transportation System (MTS) performance measures is an ongoing and collaborative effort by a number of Federal agencies, including the Committee on the Marine Transportation System (CMTS), US Army Corps of Engineers (USACE), US Department of Transportation (USDOT), Maritime Administration (MARAD), US Coast Guard (USCG), National Oceanic and Atmospheric Administration (NOAA), Saint Lawrence Seaway Development Corporation (SLSDC), US Environmental Protection Agency (EPA), Bureau of Transportation Statistics (BTS), Federal Maritime Commission (FMC), National Transportation Safety Board (NTSB), Oak Ridge National Lab (ORNL), Oceanographer of the Navy, and The Volpe Center.
This page visually summarizes various MTS performance measures in several different categories.
The U.S. Coast Guard investigates maritime-associated incidents, including vessel groundings, accidents at sea, and maritime casualties.
This data does not provide insight into the number of incidents or the availability of investigators.
The U.S. Coast Guard investigates and reports on accidents and other events associated with our national waterways, this includes both recreational and commercial (non-recreational) vessels.
Once a case has been resolved, a limited number of facts about the case are released through the USCG’s MISLE Data files.
For unresolved cases the only information available is the total number of cases, shown in grey in the bar graph to the left, these could be either recreational or commercial.
