recoprocal transplant experiments between harsh reefflat pools and the mild open ocean determined relative roles of environment and genes in growth
outdoor experiments with water flow and other parameters show water motion reduces bleaching from higher water temperature

reef fishes lower diversity on Rose Atoll than on Tutuila
This argues that algae are more important than corals in the functioning of reef communities

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 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 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.
