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.

Clinical Observations of Ocular Disease in Hawaiian Monk Seals (Monachus schauinslandi)

From abstract: In 1995, 12 undersized, weaned female Hawaiian monk seal pups were captured at French Frigate Shoals in the Northwestern Hawaiian Islands... Eleven of the pups developed clinical signs of an eye disease between 12 and 46 days after capture... The cause of the eye disease and the site where it originated remain unknown.

Comprehensive Evaluation of Shallow Reef Fish Populations at French Frigate Shoals and Midway Atoll, Northwestern Hawaiian Islands (1992/93,1995-2000) (open access)

Comprehensive Evaluation of Shallow Reef Fish Populations at French Frigate Shoals and Midway Atoll, Northwestern Hawaiian Islands (1992/93,1995-2000)

From abstract: This document represents the sixth and last of a series of Honolulu Laboratory reports providing estimates of shallow reef fish population densities based on diver-surveys conducted at roughly annual intervals at two sites (French Frigate Shoals (FFS) and Midway Atoll (Midway) in the Northwestern Hawaiian Islands (NWHI)). The purpose of the time series has been to develop the capability to characterize the standing stock densities of shallow reef fishes, as one potentially important component of the monk seal forage base with precision sufficient to detect twofold changes over a decadal time scale when sampled at a yearly frequency.

Corrected Catch Histories and Logbook Accuracy for Billfishes (Isiophoridae) in the Hawaii-based Longline Fishery (open access)

Corrected Catch Histories and Logbook Accuracy for Billfishes (Isiophoridae) in the Hawaii-based Longline Fishery

From abstract: This paper presents corrected catch histories, standardized catch rates, and evaluations of the accuracy of federally mandated commercial logbooks for billfishes taken as incidental catch by the Hawaii-based longline fishery. The study was conducted because billfish misidentifications in logbooks caused by similarities in body size, shape, and coloration have long represented a major challenge in monitoring this fishery.

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.
