Take a virtual journey to Penobscot Bay, Maine, to see how harbor pilots use U.S. Integrated Ocean Observing System (IOOS®) data for real-time ocean and weather conditions. This information is critical for safe navigation as pilots carefully move tankers and other vessels often carrying dangerous cargo safely in and out of port. IOOS coastal and marine data (e.g., water temperature, water level, currents, winds, and waves) are collected by many different tools including satellites, buoys, tide gauges, radar stations, and underwater vehicles. Most of the data collected are streamed online and viewable on digital maps for easy access.
