NOAA’s quest to better understand the world’s seafloor continues, as the National Oceanic and Atmospheric Administration has committed two of its ships to collect and update chart data in the Arctic.
For the past three years we’ve used electronic charting, combined with GPS, for navigation. For instance, on a recent overnight trip from New York Harbor
AIS networks are a mighty addition to any onboard suite of electronics. They have significant value, but also limitations.
