An Experimental Study of Phase Variations in Line-of-Sight Microwave Transmissions

From Introduction: "The purpose of this report is to present an analysis of time variations in: (1) the phase (relative to a stable phase reference) if a 9414 Mc/s signal transmitted over this path, referred to hereafter as single-path phase data; (2) the phase observed at one receiving antenna relative to that observed at an adjacent antenna, referred to as phase difference data; (3) atmospheric refractivity as recorded by a microwave refractometer located at the Haleakala terminal; (4) the wind velocity at both ends of the path, and (5) surface atmospheric refractivity measured at 5 stations located on or near the path."

Investigation of Waikele Well No. 2401-01, Oahu, Hawaii: Pumping Test, Well Logs and Water Quality (open access)

Investigation of Waikele Well No. 2401-01, Oahu, Hawaii: Pumping Test, Well Logs and Water Quality

Introduction: A dependable water supply is required for Naval Magazine Lualualei, Waikele Branch. The water supply for Naval Magazine Lualualei, Waikele Branch, Oahu, Hawaii has been dependent on Oahu Sugar Co.'s water for many years. Because the supply of water from Oahu Sugar Co. is not always dependable, in March 1982, the Pacific Division of the Naval Facilities Engineering Command entered into a cooperative agreement with the U.S. Geological Survey to determine the productivity and water quality of an abandonment Navy well. The well, No. 2401-01, is located in Waikele Gulch near the confluence of Waikele and Kipapa Streams (fig. 1.0-1)

The Effects of Pumpage, Irrigation Return, and Regional Ground-Water Flow on the Water Quality at Waiawa Water Tunnel, Oahu, Hawaii (open access)

The Effects of Pumpage, Irrigation Return, and Regional Ground-Water Flow on the Water Quality at Waiawa Water Tunnel, Oahu, Hawaii

From executive summary: Studies of the salinity problem at Waiwa shaft by the Public Works Center, Fourteenth Naval District, Pearl Harbor, have indicated that the increasing salinity is due to contamination from irrigation-return water or seawater intrusion. Because of the concern over the continuing deterioration of their principal source of water, the Pacific Division, Naval Facilities Engineering Command requested the U.S. Geological Survey to undertake this study.

From abstract: A stock assessment of the main Hawaiian Islands "Deep7" bottomfish complex was conducted through fishing year 2010, including projections to determine total allowable commercial catches (TACs) and their probabilities of overfishing. This assessment was conducted using re-audited bottomfish catch and effort data from commercial catch reports for the years 1948-2010.

Censuses and Interatoll Movements of the Hawaiian Monk Seal on Laysan Island, 1985 (open access)

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.

Research Plan for Marine Turtle Fibropapilloma

The following report is the results of a workshop held to determine the cause of fibropapilloma (lobulated tumors), thereby ultimately leading to solutions and effective strategies for containment. The urgent need to solve this problem arises from the unanimous belief among the workshop participants that this disease will continue to affect populations of turtles locally and worldwide, adding further to their survival difficulties. The workshop was held in December of 1990 and the research behind the workshop results from about 10 years of observing the species.
