Advancements in Arctic Hydrographic Operations and Unmanned Systems: OTWG ARHC9 Report

DESCRIPTION

The OTWG report from Arctic Regional Hydrographic Commission (ARHC9) details significant advancements in Arctic hydrographic operations, particularly focusing on unmanned systems. Key sections discuss collaborations with institutions like UNH and NOAA, personnel exchanges between the U.S. and Canada, and recommended actions for hydrographic adequacy risk assessments and vertical datum evaluations. The report highlights operational models tested in Arctic surveys and emphasizes the importance of updating data quality assessments every five years to support marine navigation and safety in polar regions.
