The U.S. National Oceanographic Data Center (NODC) periodically receives a standard suite of shipboard sensor data (also known as underway data) from each NOAA ship with the Scientific Computer System (SCS). These data include measurements of salinity and temperature from thermosalinographs, bottom depth, wind speed and direction, atmospheric temperature, pressure and humidity, position and date/time. The NODC archives, quality-controls, and loads these data into the Shipboard Sensor Database (SSD), which may be queried by date, position, and data type, and from which data may be downloaded.
The SCS was developed by NOAA Marine and Aviation Operations to acquire data from a ship's meteorological, oceanographic, fishery, and navigational sensors and to provide these data to scientists in real time. The NOAA ships shown above and below are currently equipped with the SCS.
