The dataset provides geotiff maps depicting coral growth and survival favorability in Guam and American Samoa under three climate scenarios, derived from various environmental factors. Scores between 0 and 1 indicate coral conditions, with 0 being the worst and 1 being the best, as detailed in the 2022 manuscript "Where favorable environmental conditions and resilient corals coincide: Guam and American Samoa".
Climate change disproportionately affects developing countries due to its impacts on agriculture, water supplies, and natural disasters, jeopardizing progress in poverty reduction and threatening the well-being of billions. The World Bank Group is actively aiding these nations by addressing climate challenges through tailored approaches, encompassing data on climate systems, resilience, emissions, and various sectors like health and infrastructure.
This dataset comprises water temperature data collected through subsurface temperature recorders (STRs) for monitoring seawater temperature variability at permanent coral reef sites in American Samoa. Deployed as part of the NOAA National Coral Reef Monitoring Program (NCRMP), these high-accuracy temperature loggers, manufactured by SeaBird Electronics (SBE), operate at depths of 0 to 30 meters along depth transects at Ocean and Climate Change monitoring survey sites for 3 years. Recovered STRs are replaced with new deployments in the same location.
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.
Sea level anomalies in the tropical Pacific, influenced by events like El Niño and La Niña, pose risks to islands due to fluctuations in mean sea level. Advanced climate models and a multimodel ensemble approach offer improved forecasting, aiding Pacific island communities in mitigating the impacts of sea level extremes.
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).
Ground-water and rainfall data from Tutuila and Aunuu in American Samoa, spanning October 1987 to September 1997, reveal trends in pumpage, chloride concentrations, and water levels. Noteworthy findings include varied pumpage rates and chloride concentrations, with Aua experiencing record-high chloride levels, while water levels in certain areas remained consistent or declined during the 12-month period ending September 1997.
This tool provides rain data in American Samoa from 1945-2024. The desired year and month can be selected.
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.
The data described here is from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted in Aua Reef, American Samoa, by scientists of the Ecosystem Sciences Division (ESD) of the NOAA Pacific Islands Fisheries Science Center (PIFSC). The NOAA Fisheries, Ecosystem Sciences Division established 18 survey sites along the water quality gradient near land-based source pollution. This is part of a larger collection of datasets collected as part of the CRCP-funded project 'Linking watershed management activities to reef health in American Samoa' (project no. 31303).
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.
Flask CO2 and isotopic data sets taken at American Samoa: Latitude 14.2°S Longitude 170.6°W Elevation 30m. These data are subject to revision based on recalibration of standard gases.
The Weather Research and Forecast model (WRF) utilizes triply-nested meshes with varying horizontal resolutions (20 km, 4 km, and 0.8 km) to cover tropical and subtropical regions. The atmospheric driving fields, sourced from NASA's Modern-Era Retrospective Analysis and NOAA's sea surface temperature, include variables like temperature, wind, geopotential height, and water vapor. The Pseudo-Global-Warming method incorporates global warming signals from 12 CMIP5 models for future runs, spanning from January 1st, 2080 to December 31st, 2099, under RCP4.5 and RCP8.5 scenarios.
The data includes tide gauge readings from before 1950 until the present in Pago Pago.
