Structured Flotsam as Fish Aggregating Devices
Abstract: A modern adaptation of an old fishing technique is gaining recognition in the Pacific and elsewhere as an effective means to increase fishing productivity in the open sea. The use of man-made, free-floating, and anchored floating devices to aggregate pelagic fishes for subsistence, recreational and commercial fishing has increased markedly in recent years; estimates of deployed and planned units exceed 1,000. These devices have been anchored in depths ranging from several hundred to several thousand fathoms. This report reviews the development and present use of fish aggregating devices in the Pacific and Indian Oceans.
Possible Effects of Sampling Biases on Reproduction Rate Estimates for Dolphins in the Eastern Tropical Pacific
From introduction: The purpose of this report is to present a sensitivity analysis on the effects that biased sampling of young calves and lactating females would have on the various estimated life history parameters. This sensitivity analysis provides one measure of reliability of the various estimates. Also, where inconsistencies in the estimates can be identified, this analysis provides one means for evaluating which estimates are likely in error.

Population Monitoring of the Hawaiian Monk Seal, Monachus schauinslandi, and Captive Maintenance Project at Kure Atoll, 1988
Abstract: Data on the Hawaiian monk seal, Monachus schauinslandi, were collected at Kure Atoll from 23 February to 20 October 1988. Beach counts made on 54 atoll-wide censuses averaged 30.0 seals, including pups of the year. Eight pups (five females and three males) were born; seven survived to weaning. Thirteen injuries to 12 seals were documented, and 5 seals became entangled in marine debris. An estimated 1,195 kg of debris were removed from beaches. Thirty-two of 40 seals tagged at Kure Atoll since 1981 were resighted. Five weaned female pups were maintained in a protective enclosure until 20-21 September, and a yearling Kure Atoll seal, which had been rehabilitated in Honolulu, was maintained in the enclosure from 22 March to 12 May.
Field Manual for Phocid Necropsies (Specifically Monachus schauinslandi)
From introduction: This necropsy manual is a guide for students and technicians in the examination of dead phocids, specifically the Hawaiian monk seal. With this manual, the person performing the necropsy should be able to conduct a gross examination of a monk seal and collect the necessary tissues for microscopic pathology and toxicological studies. The necropsy instructions are based on the assumption that the seal's carcass is very fresh and time is not a limiting factor.

Censuses and Interatoll Movements of the Hawaiian Monk Seal on Laysan Island, 1985
Abstract: Research on the Laysan Island population of the endangered Hawaiian monk seal, Monachus schauinslandi, was conducted from 2 march to 30 November 1985. census totals excluding pups ranged from 76 to 147, an average increase of nearly 20 animals from the 1984 census results. Overall monthly haul-out distribution for all seals showed highest use in the north ecological unit followed by the west unit. Relatively few animals hauled out in the eastern and southern portions of the island. Interatoll movement of nine seals was documented, resulting in a net increase of three animals to the Laysan Island population.
Mineral industry of Alaska in 1934
From Introduction: "The value of its mineral resources has long been recognized as a matter of concern in the welfare of every nation, and all wise governments almost from time immemorial have taken steps to find out about, utilize, and safeguard such of these natural resources as lie within their own boundaries or to acquire rights in those they need that lie outside those boundaries. Obviously one of these lines concerns itself with the record of present performance-how much of the different mineral commodities is the country at present producing, where does this production come from and what are the facts as to the current developments in the industry? To answer some of these questions authoritatively is part of the work of the Alaskan branch of the Geological Survey, and answers to those questions for the year 1934 are given in the accompanying report."

Tungsten Deposits of the Nightingale District, Pershing County, Nevada
Abstract: The tungsten deposits of the Nightingale district are just within the western border of Pershing County, Nev., and in the Nightingale or Truckee Range, which lies east of Winnemucca Lake. The Tertiary volcanic rocks of the district rest unconformably upon intrusive granodiorite and steeply dipping metamorphosed limestones and slates of unknown age. The tungsten deposits are of the contact-metamorphic type: The ore consists of scheelite bearing tactite, a dark silicate rock that was formed by metamorphism of limestone at the granodiorite contact. Scheelite (calcium tungstate) is the only valuable mineral. The gangue minerals are epidote, quartz, pyroxene, garnet, calcite, tremolite, molybdenite, pyrite, pyrrhotite, chalcopyrite, arsenopyrite, apatite, and sphene. The bodies of tactite are generally tabular, and they extend downward steeply, because both the limestones and the granodiorite contact dip vertically or nearly so. The largest tactite body of the district is at the Nightingale mine; it attains a maximum thickness of 60 feet and is nearly a thousand feet long, but only for part of its length is it thick enough and rich enough to be potentially minable. That it continues downward below the mine workings, which extend to a depth of 128 feet, is shown by nine drill holes put down by the Bureau of Mines, United States Department of the Interior, in 1940, all of which encountered tactite at depths of, 260 to 350 feet. The mine has produced about 12,000 tons of ore, and its ore bodies contain the principal reserve of the district. In 1938 the reserves of the entire district were estimated to be about 50,000 tons of ore averaging between 0.25 and 0.50 percent of W03. Later diamond drilling by the Bureau of Mines indicated that the principal tactite body continues to at least twice the depth hitherto explored by the mine workings.
Topaz Deposits Near the Brewer Mine, Chesterfield County, South Carolina
From introduction: Lode and placer deposits of massive topaz rock were discovered near the old Brewer gold mine in northwestern Chesterfield County, S. C., in 1935. Preliminary tests have shown that this rock can be used in the manufacture of refractory ware and as a source of mullite, thus augmenting supplies of kyanite that have been coming from India.
Tungsten Deposits in the Sierra Nevada Near Bishop, California: A Preliminary Report
From abstract: Scheelite ore bodies occur at widely separated localities in the Sierra Nevada near Bishop, Calif. The scheelite is found in altered sedimentary rocks at or near the contact between granitic rocks and limestones that are partly changed to silicate rocks composed largely of garnet. Mineralization was closely connected with the intrusion of the granite, the latest of the varied intrusives that make up the rocks of the Sierra Nevada.
Quicksilver deposits in the Steens and Pueblo mountains, southern Oregon
From Abstract: "This report describes the occurrence of the mica and its physical properties among which is an unusually wide range of colors. A table is presented showing the results of power-factor measurements made by the National Bureau of Standards on 196 samples of sheet mica from 109 mica mines and 15 feldspar mines.It is concluded that more systematic planning of mica mining, for the district as a whole. would result in an average yearly production of at least 90,000 pounds of relatively clear sheet and possibly much more."
Quicksilver deposits in the Steens and Pueblo mountains, southern Oregon
From Scope of Report: "During the summer of 1940, 34 days were spent in a preliminary study of the quicksilver deposits in the Steens and Pueblo Mountains. Nearly all of the quicksilver prospects were examined and mapped, and the general geology of the east flank of the mountains from north of Andrews to Denio was reconnoitered."
