Oregon State University's PRISM Group conducted a project to create updated climate maps for various Pacific island regions, including the Hawaiian Islands, Guam, CNMI, Palau, American Samoa, and the Federated States of Micronesia. These maps, produced at high resolution, encompassed temperature and precipitation data for the period of 1971-2000, aiding in climate analysis and resource management for these areas.
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.
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.
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.
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.
American Samoa boasts rich coral reefs fringing its islands, with coral reef protection integrated into a national system, including management by the National Park of American Samoa and the National Marine Sanctuary Program. The division between American Samoa and independent Samoa is relatively recent, with intertwined pre-Western histories and cultural connections that endure today among all Samoan Islands.
