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.
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.
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 report focuses on addressing the critical challenges of sustainable water resources management on Tutuila, the main island in the Territory of American Samoa. It presents an updated conceptual hydrogeological model of the island's groundwater and surface water resources by integrating existing hydrological information with recently acquired subsurface datasets, shedding light on the complex nature of Tutuila's hydrogeology, which varies significantly across different locations on the island.
This report documents the UH monitoring network which provides hydrologic parameters, such as precipitation, streamflow, and aquifer response, in small island developing communities like Tutuila, American Samoa, where water resources are limited. It highlights the collaborative efforts between the University of Hawaii's Water Resources Research Center and the American Samoa Power Authority to establish a new monitoring network for weather, stream gauging, and aquifer data, providing essential information for sustainable water resource management and various applications

Soil Survey and analysis by Hawaii State Office, Soil Conservation Service, US Department of Agriculture, Honolulu, Hawaii. The field survey was completed in November 1981.
The Integrated Feasibility Report and Environmental Assessment (IFR/EA) is a study led by the Honolulu District of the Pacific Ocean Division of USACE, with the American Samoa Government as the non-Federal sponsor. It focuses on addressing flood risk in the Tafuna-Leone Plain of Tutuila Island, which is densely populated and vulnerable to frequent flooding due to heavy rainfall, shallow stream channels, and various development-related factors.
This report presents findings from the analysis of radiocarbon dates and volcanic stratigraphy in the Leone Volcanics region of Tutuila Island, American Samoa, shedding light on the timing and spatial distribution of late-Holocene volcanic events. Key insights include identifying a distinct reddish ash stratum dating to approximately AD 650-750 as the most recent eruptive event, along with observations on the source and sequence of ash deposits, suggesting multiple eruptive events from both seaward and inland craters, potentially continuing as recently as AD 1300.
This paper presents over 100 radiocarbon dating results for Tutuila and Manu'a in American Samoa, contributing to various aspects of Samoan archaeology.
