Keep Charts Current with NOAA Blog

NOAA’s new blog dives deeper into navigational products and services.

The new NOAA Coast Survey blog is diving deeper with brief vignettes about the hydrographic technologies and nautical charting products that support maritime commerce, respond to maritime emergencies, protect coastal life and property, and explore marine archeology.

NOAA representatives are excited to start this new venture. The blog platform gives NOAA hydrographers and cartographers a platform for sharing insights into the technologies, using a blend of photos, illustrations, and personal observations.

This month, blog writers are focusing on NOAA Ship Fairweather's 30-day reconnaissance survey into the Arctic. For instance, the post Fairweather zigzags her way to depth soundings gives insight into the survey operations that follow up on 140 years of Coast Survey work in Alaskan waters. Scientists and crew onboard the ship will be sharing their logs, and the blog will track the ice cover as the ship approaches Barrow later next week. (Will there be enough open sea to allow safe transit past Barrow to the Canadian border?)

NOAA's Office of Coast Survey has been the nation's nautical chartmaker for two centuries. Coast Survey contributes nautical charts, hydrographic data, and navigational assistance to the full range of NOAA's navigational services.
