Video signals from the Aialik
Bay cameras are routed to the Alaska SeaLife Center via microwave
through several repeaters. |
 |
One of the cameras is mounted
high on a cliff above the terminus of Aialik Glacier, providing
a birds-eye view of both ice cover and harbor seal abundance. |

icebergs calved from the glacier as safe resting, pupping and
nursing locations. (photo © David William Miller) |

In the early 1980's, harbor
seals were much more abundant in Aialik Bay than they are today.

Technicians adjust one of the
cameras while Shannon Atkinson, Science Director at he Alaska
SeaLife Center, looks on. The cameras are powered by both wind
and solar panels, and the signals transmitted via microwave. |

This aerial view shows upper
Aiailik Bay, where Aialik calves icebergs into the ocean that
harbor seals use for resting, pupping, and nursing. |

Tour vessels, as well as kayakers,
have become much more common near Aialik Glacier over the last
two decades. Researchers want to know if their presence disturbs
seals resting on the ice. |

A remote camera array located
on Squab Island, near the face of Aialik Glacier, provides a live,
round the clock view of harbor seal activity. |
