This Natural Resource Data Series Report (NRDS) presents data collected from anchialine pools associated with the Ala Kahakai National Historic Trail on the west coast of the island of Hawai`i, Hawaii. This is a summary or “data report” as described in the Water Quality Vital Signs Monitoring Protocol for the Pacific Island Network Version 1.0, Natural Resource Report NPS/PACN/NRR-2011/418. This report is restricted to data presentation and limited description. The data presented in this report will be analyzed for the establishment of expected parameter value ranges and long-term trends in future reports published in the NPS Natural Resource Technical Report (NRTR) series. The purpose of collecting data on Vital Signs is to provide park managers information on current conditions and temporal trends in ecosystem health. Four anchialine pools were sampled up to 17 times from the first quarter of 2008 through 2011. Two major events occurred during the sample period: a tsunami on 11 March 2011, and extensive restoration of one pool (F-ALKA-01) by the State of Hawaii. The tsunami buried one pool (F-ALKA-02) such that water no longer reached the surface, and hence sampling was suspended. Inundation by seawater into F-ALKA-01 was observable as elevated salinity 21 days later but not 48 days later. No notable events were observed in the two subterranean pools F-ALKA-03 and F-ALKA-04.
