In the early 1980's, two shipping vessel collisions at the Tampa Bay Sunshine Skyway Bridge happened within weeks of each other. These accidents spurred Federal legislation leading to the development and establishment of NOAA's first Physical Oceanographic Real Time System (PORTS®) in 1991. This July, PORTS celebrates 30 years of providing commercial vessel operators with accurate and reliable real-time environmental conditions to enhance the safety and efficiency of maritime commerce.
