In collaboration with its partners, the National Oceanic and Atmospheric Administration’s Center for Operational Oceanographic Products and Services (CO-OPS) is excited to share a training video about the International Great Lakes Datum (IGLD), located here. IGLD is the official water level reference system for the Great Lakes, their connecting waterways, and the St. Lawrence River. The system is needed for safe marine navigation, water level regulation, surveying, mapping, shoreline use planning and restoration, and more.  

The purpose of the training video is to educate technical users on the current IGLD (1985) and expected changes with the new IGLD (2020). It provides foundational knowledge of the IGLD, covering its historical context, the collaborative efforts between the U.S. and Canada for a binational update, and potential impacts for the expected 2027 update.

THSOA Southeast Chapter Scholarship 2024:
Congratulations to our recipients!

The Southeast chapter of The Hydrographic Society of America is pleased to announce that we have awarded $14,000 in scholarships for the 2023-2024 academic year. We had 15 applicants this year and, although they were all worthy, it just was not possible to awarded everyone a scholarship. I want to thank the hard work of the SE Chapter  education committee in determining who was awarded.

We thank all of our sponsors of our events throughout the year. Without them none of this would be possible.

We are devastated by the sudden loss of our colleague and dear friend Don Ventura. With an impressive career, Don was an IHO Category ‘A’ Charge Surveyor, Fellow and Chartered Marine Scientist (Hydrography) with the Institute of Marine Engineering, Science and Technology (IMarEST); he was engaged in hydrography since 1984. His experience included 22 years’ service as a hydrographic surveyor in the British Royal Navy, (including 3 years’ exchange with the US Navy at the Naval Oceanographic Office, Stennis Space Center, Mississippi), 3 years employed with SAIC (now Leidos) and 14 years with Fugro. Don was a passionate and dedicated member of the Teledyne Geospatial Product Management Team leading Bathy Lidar Solutions, which greatly benefitted from his tenured experience and professional accreditations. Don’s enthusiasm for the people and technology was evident to everyone who worked with him.
