A comprehensive fish and sediment sampling effort was conducted at the central San Juan Channel sand wave field, a region where bottom currents have shaped the seafloor geomorphology into a series of successive crests and troughs at depths of 60-80 m to determine sediment associations of Pacific sand lance in offshore waters.
Sand Lance also occur in deep water (>30 m) on sand wave fields in the San Juan Channel (Blaine 2006; Gary Greene, Tombolo Institute, Orcas Island, WA, pers.

The ultimate wow piece is the dramatic "sand wave" installation in the ceiling of the lobby.

The sand wave field experienced a net migration to the southwest of about 17 m/yr; the maximum distance moved in two years was 49 m.
Pipelines sometimes have to cross a sand wave field.
Sand Waves series is a collection that personify the image of Absheron peninsula in summer, a favorite spot to relax for many generations of local residents.
Beluga whale critical habitat, salmon fisheries, 40-foot boulders, 15-foot-tall sand waves along the ocean bottom, strong currents, shallow water close to shore, ice scouring that could expose or damage a pipeline - all present problems best avoided as much as possible as Alaska.
Sediment transport and sand waves will be studied in this highly dynamic area (6 knot currents).
