Augustine Island

Augustine Island

(ô`gəstēn, –tĭn; ôgŭs`tĭn), unihabited volcanic island, S Alaska, in Kamishak Bay at mouth of Cook Inlet. The active Augustine (or St. Augustine) volcano, which forms the entire island, rises to 4,134 ft (1,260 m); ash from its last major eruption (1986) reached Anchorage, some 180 mi (290 km) to the northeast. The 1883 eruption is believed to have caused a 30-ft (9-m) tsunami locally.

Additional maps show a series of offshore transects with latitudes and longitudes noted at endpoints, crossing the mid-Inlet from the Forelands to Ninilchik then circling Kalgin Island and resuming coastal survey at West Foreland headed south with a spoke pattern of tracklines off Augustine Island. These appeared to be proposed tracklines.
Cloudy and choppy in AM, sunny and light breeze in PM." The second map shows trackline from Ursus Cove to Augustine Island with an otter in Ursus Cove: "Sea otters sighted on Belukha survey 4/9/78." The third map shows beluga sightings in Chinitna Bay and Iniskin Bay with trackline from Tuxedni Bay to Ursus Cove, simply identified as: "Survey 4/9/78." Only this map shows the composition of the beluga groups: Chinitna Bay (21 including 4 gray moving into the bay + an additional 4 gray juveniles in the bay), and Iniskin Bay (23-30 (total given as 27 + 2 gray)).
A composite map showing both the April 7 and April 9 surveys included tracklines and the beluga group totals (with the Akumwaruk Bay sighting closer to the spot where the aircraft turned offshore to fly back to Augustine Island).
I saw 3 harbor seals in the cove off the southwest corner of Augustine Island. We saw 3 bears along the shoreline of Iniskin Bay.
The aircraft headed offshore to begin a spoke pattern off Augustine Island, circling the island ("100s HS" 100s of harbor seals on south shore + "2 HS" on north shore) then heading to shore at Bruin Bay then surveying the shoreline north to Ursus Cove ("25 HS" 25 harbor seals south of Ursus Cove) before heading back offshore where the trackline ends.
The map on 18 August shows the trackline beginning offshore (labeled "I"), northeast of Augustine Island. The aircraft entered Tuxedni Bay, encountering 30 belugas.
The second flight (labeled "II") begins in Homer, crossing the inlet to Augustine Island, circling the island then heading to the western shoreline at Ursus Cove.
The second flight departed Homer crossing the bay to Sadie Cove following the shoreline south to English Bay then crossed the inlet to Augustine Island. From Augustine Island the track followed the ice edge to Cape Douglas then turned north to survey along the ice edge into Kamishak Bay to Ursus Cove.
20 that the Augustine Island volcano in Alaska entered a new phase of activity, the third outburst since it erupted last March 27 (SN:5/17/86, p.309).
