The ability of corals to adapt to climate change relies on the existing genetic variation for climate-related resistance. By genotyping 15,399 single nucleotide polymorphisms in Acropora hyacinthus corals within a naturally variable temperature environment, 114 highly divergent SNPs were identified as potential candidates for environmental selection, indicating the presence of alleles preadapted to high temperatures in the population.
This document, serving as both the Final Management Plan (FMP) and Final Environmental Impact Statement (EIS), outlines proposed revisions to sanctuary regulations led by the National Oceanic and Atmospheric Administration (NOAA) and involves collaboration with the American Samoa Department of Commerce (AS DOC).
Marine biological surveys were conducted at American Samoa on the Island of Tutuila between 21 April - 5 May, 1974. The surveys were in response to the U.S. Army Corps of Engineers request for examination of the marine environment where potential storm damage mitigation projects are proposed.
This booklet describes the U.S. Army Corps of Engineers' role in water resources development and the Pacific Ocean Division and Honolulu Engineer District have been assissting the Government of American Samoa in the management and development of the territory's water resources. The "urbanization" of American Samoa and the accompanying desires for modern conveniences have placed heavy demands on the territory's fragile infrastructure, including its vital resource.
This document details the appendices for the vulnerability assessment. It examines topics such as stakeholder summary notes, climate data inventory, sources, and relevant literature.
The preservation of our environment is a vital and growing concern in the United States. This report is to assist in the implementation of the regulation of these areas, the U.S. Army Corps commissioned a survey and preparation of a report on the wetlands of American Samoa.
This report details a wide variety of beach aspects in American Samoa. That includes flood control, beach erosion, and environmental protection.
This study of the baseline water quality in American Samoa covered the effects of wet and dry seasons and a variety of tide and weather conditions on water quality and exchange characteristics of several water classifications. Current measurements in the Tafuna area show a reversing tide related longshore current with net transport towards to the southwest.
This report has been prepared by the U.S. Fish and Wildlife Service for inclusion in the U.S. Army Corps of Engineers American Samoa Water Resources study, and will contribute to the development of a comprehensive plan
The drainage basins of Tutuila are quite similar topographically and produce similar amounts of runoff. Hydropower is not feasible due to low or intermittent flow in streams.
This study investigates the status of giant clam populations, at Rose Atoll, Samoa, revealing its significance as a refuge with high clam densities and low mortality rates.
