Glacier Bay National Park Superintendent, Cherry Payne, has asked all mariners to exercise caution to avoid harbor seals hauled out on floating glacier ice in Glacier Bay and elsewhere. Harbor seals often utilize floating ice in glacial fjords, but are especially vulnerable during the summer pupping and molting seasons.

Recently, seals with pups have been reported on floating ice just outside of Johns Hopkins Inlet, Jaw Point, and Tarr Inlet in areas frequented by cruise ships and other vessels. Wind can push floating ice fairly rapidly, so conditions may change from day to day or even hour to hour. When disturbed, the seal pups can be separated from their mother, with potentially fatal consequences. Disturbances by passing vessels can also stress molting seals and impact their health. Mariners are urged to maintain at least one quarter mile distance from seals hauled out on ice. Mariners should also reduce speed and maintain a greater distance if the seals appear agitated by the vessel’s approach. To protect harbor seals, Johns Hopkins Inlet is closed to all vessel traffic from May 1 until June 30, and closed to cruise ships until August 31 each year.  

Superintendent Payne recommends that mariners keep a sharp lookout for seals in these and other areas, and take early action to minimize any disturbance. As a reminder, park regulations and the Marine Mammal Protection Act prohibit the harassment of harbor seals and other marine mammals.

Glacier Bay has a maritime climate, heavily influenced by ocean currents. The result is mild winter and cool summer temperatures at sea level. Summer visitors can expect highs between 50-60F. Winter lows rarely drop into the single digits.
