Canadian Hydrographic Service Central and Arctic Region CA373286 - MELVILLE SOUND TO CABOT HEAD CABLES For the mariners' safety, all submarine and overhead cables are assumed to conduct electric power at high voltages and contact with or proximity to these poses an extreme danger. 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. However, if anchors become hooked onto a cable, care must be taken not to sever the cable. Cables installed since the date of publication of this ENC may not be charted. Sufficient clearance must be allowed under all overhead cables. Actual clearances may differ from charted values due to changes in atmospheric conditions, ice buildup and/or water levels. For additional information, consult Notice to Mariners No. 16 of each year and the appropriate volume of CHS Sailing Directions. See Notices to Mariners for subsequent corrections on this chart and Notices to Shipping in force for hazards or changes essential for the safety of navigation. © Fisheries and Oceans Canada 2019.
