Mariners are advised to exercise caution when passing under all overhead cables and to avoid anchoring or conducting seabed operations in the vicinity of submarine cables.  The clearance of an overhead cable may differ from its charted value due to changes in atmospheric conditions, water levels and other factors.  For additional information, consult Notice to Mariners No. 16 of each year and the appropriate volume of CHS Sailing Directions.
