The Hawaiian Monk Seal in the Northwestern Hawaiian Islands, 1995 (open access)

The Hawaiian Monk Seal in the Northwestern Hawaiian Islands, 1995

The following report is based on findings from the observational studies on the Hawaiian monk seal in the Northwestern Hawaiian Islands during 1995. The objectives of this research were to conduct beach counts (censuses), tag weaned pups and immature seals for permanent identification, identify other seals by previously applied tags and by natural or applied markings, monitor reproduction, survival, injuries, entanglements, interatoll movements, disappearances, and deaths, perform necropsies, collect tissue samples for DNA analysis, and inventory, sample, and destroy debris capable of entangling wildlife.

Proterozoic Geology of the Granite Village Area, Albany and Laramie Counties, Wyoming, Compared with that of the Sierra Madre and Medicine Bow Mountains of Southeastern Wyoming (open access)

Proterozoic Geology of the Granite Village Area, Albany and Laramie Counties, Wyoming, Compared with that of the Sierra Madre and Medicine Bow Mountains of Southeastern Wyoming

Abstract: "Precambrian metavolcanic rocks north and south of the village of Granite, Wyoming, belong to a sequence of isolated metavolcanic and metasedimentary masses in the Sherman Granite of the southern Laramie Mountains. Similar rocks lie to the west, in the Precambrian uplifts of the southern Medicine Bow Mountains and Sierra Madre. A major fault system, the Cheyenne belt, splits these two ranges into northern and southern domains, and may constitute a suture along which Early Proterozoic islands arcs collided with an Early Proterozoic passive margin. Projection of the Cheyenne belt into the Laramie Mountains suggests that the study area, which is 65 kilometers south of the proposed suture, comprises a distinct volcanic arc with a unique chemistry or age. However, chemistry of the volcanic rocks of the study area as determined as so far does not differ significantly from those of the Medicine Bow Mountains and Sierra Madre."
