NOAA’s Hydrographic Services Review Panel held its annual meeting earlier this week in Portsmouth, NH. Substructure was there to demonstrate our hydrographic and maritime archaeological survey capability on survey vessel Mintaka. We will be running multibeam demonstrations through next week. If you are interested in coming aboard to survey the Piscataqua River, and see what we can do for you, please contact Carol by email or phone (603-957-1045). Demos will be approximately 2 hours total time.
