  Bogoslof Volcano, Alaska   (Site not responding. Last check: 2007-11-02)
Bogoslof is the emergent summit of a submarine volcano, situated 40 km north of the main Aleutian arc.
Castle Rock (Old Bogoslof) is a steep-sided pinnacle that is a remnant of a spine from the 1796 eruption.
Fire Island (New Bogoslof), a small island located about 600 m NW of Bogoslof Island, is a remnant of a lava dome that was formed in 1883.

 Bogoslof - Activity
Its surface is often rough and blocky as a result of fragmentation of the cooler, outer crust during growth of the dome.
Old Bogoslof, Fire Island, and the southwest shore of the lagoon remained the same as in the preceding year, but the new spines had become connected with the northeast shore of the lagoon, and a portion of the shore on that side had risen ten feet.
Forked lightning in the direction of Bogoslof was seen before daylight, and when Bogoslof was sighted the new central peak was seen to be in a state of eruption.

Bogoslof Island is an intriguing place, and I feel fortunate to be on a team of biologists surveying its wildlife.
The refuge lands are scattered from Forrester Island in Southeast Alaska to the Barren Islands near Homer, along the Alaska Peninsula to the end of the Aleutians, across the Bering Sea to the Pribilofs and St. Matthew and north to Cape Lisburne in the Chukchi Sea.
Bogoslof itself was one of the early refuges designated in 1909 and later combined with other insular refuges and new lands to form the Alaska Maritime National Wildlife Refuge.

Bogoslof Island showed little to no habitation by northern fur seals prior to the 1970’s.
Although the sporadic distribution of northern fur seals around the world makes it difficult for scientists to accurately estimate their populations, it is commonly agreed that a majority of the world’s fur seals occur in Alaska.
Because adult fur seals are often at sea and difficult to study, scientists take a census of seal pups at the Pribilof and Bogoslof rookeries to examine biological trends and to estimate the total number of fur seals in Alaska.

While on Bogoslof conducting this research, we will also have the opportunity to obtain a new population estimate to see if the numbers of fur seals have continued to grow at such an extraordinary rate.
Because adult fur seals are often at sea, a census of seal pups is made at the Pribilof and Bogoslof rookeries to examine biological trends and to estimate the total number of fur seals in Alaska.
Bogoslof is a small island 2.0 km long and 0.75 km wide located 50 miles northwest of Dutch Harbor.

Alternatively, the degree of philopatry in walleye pollock may be extremely low despite the spatial and temporal predictability of spawning aggregations.
The temporal genetic variation we observed in Prince William Sound and Bogoslof Island is consistent with this theory.

 Bogoslof Volcanoes, Alaska Science Forum
The beginnings of the island, Bogoslof volcano, actually existed in 1768 in the form of a rock, called Ship Rock, rising sharply out of the sea.
Still, all was not done, for in 1927 a new dome thrust up in defiance of the ocean waves which over the years had steadily been eroding away the Bogoslof Islands.
The ocean may win and totally destroy the islands, but chances are that future eruptions will restore them in some form and that birds and sea lions will continue to roost there in the intervals between eruptions.

The original Harriman Expedition visited Bogoslof Island on July 8, 1899, and the current expedition is expected to be near Bogoslof Island in mid-August of 2001.
However, the expedition anticipates being in the Bogoslof Island area during the Steller sea lion and northern fur seal pupping season, and landing on the island could [[Page 37600]] have a significant adverse impact on successful reproduction or pup- rearing.
Condition of this exemption include (1) a prohibition to land on the island, (2) the expedition vessel is not allowed to operate within 1 nm of any point on the rookery, and (3) no one is allowed to enter within 500m of any point on the rookery by any means, such as an inflatable vessel.

Bogoslof is one of only four locations where Red-legged Kittiwakes breed in the Bering Sea.
In particular, although energy reserves were similar among Common Murres nesting on Bogoslof and St. Paul Is., baseline and acute stress-induced levels of corticosterone were elevated in birds at St. Paul I. compared to Common Murres nesting on Bogoslof Island.

During the period of greatest recorded land mass (late 1800s), cliff-nesting habitat was at least 17 times greater at Bogoslof and 25 times greater at Fire Island than in the 1973 when censuses were again taken on this one-mile-long island.
Cliffs along the edges of Bogoslof’s plateau are eroding at a more rapid rate than at adjacent Castle Rock, Kenyon Dome, and Fire Island.
The changes in the composition and abundance of birds on Bogoslof Island provide a ongoing example of the colonization by seabirds of a recently-formed volcano.

Juvenile male fur seals are still killed by Aleut natives on St. George and St. Paul Islands for subsistence purposes, 232 and 1,588 seals being killed on the respective islands in 1996.
Fur seals are not killed on Bogoslof Island or San Miguel Island but it is thought that 0.2-2% of the population on the Asian islands are killed each year, including 1,500 males on Tyuleniy Island and 5,000 pups on the Commander Islands.
Up to 87% of the pups born at the colony in 1997 during the 1997-98 El NiƱo died before weaning and it may take the population several years to recover.

In the mid-1980s to early 1990s, a large pulse fishery for pollock developed in the Donut Hole in the central Bering Sea and a much smaller fishery developed near Bogoslof Island (north of the eastern Aleutian Islands) beyond the eastern Bering Sea shelf (see Figure 5.5).
The Bogoslof fishery peaked at 377,000 mt in 1987, whereas the Donut Hole fishery peaked at 1.4 million mt in 1989.
Because of concerns about relationships between pollock near Bogoslof Island and those in the Aleutian Basin, the domestic Bogoslof Island fishery was closed in 1991.
