Water level, temperature and chemistry in a deep well on the summit of Kilauea Volcano, Hawaii Water level, temperature and chemistry in a deep well on the summit of Kilauea Volcano, Hawaii
Kilauea, on the Island of Hawaii is one of the world's most active volcanoes and it hosts one of the densest volcano monitoring networks. A deep well on the southwest rim of Kilauea's caldera, often referred to informally as the "NSF Well" or the "Keller Well" was drilled in 1973 to a depth of 1,262 meters from an elevation of 1,103 meters. The ultimate goal of the drilling project was...
Groundwater levels and temperatures in well CH-10b near Hot Creek, Long Valley Caldera, eastern California (ver. 3.0, March 2025) Groundwater levels and temperatures in well CH-10b near Hot Creek, Long Valley Caldera, eastern California (ver. 3.0, March 2025)
Hot Creek Gorge contains the most obvious surface expression of the hydrothermal system in Long Valley Caldera, California, discharging 200-300 L/s of thermal water according to USGS measurements made since 1988. Formerly, Hot Creek was a popular public swimming area, but it was closed in 2006 due to unpredictable temperature fluctuations and sporadic geysering of thermal water within...
Volcanic ash leachate and rainwater chemistry from increased 2018 activity of Kilauea Volcano, Hawaii Volcanic ash leachate and rainwater chemistry from increased 2018 activity of Kilauea Volcano, Hawaii
In early May 2018, activity at Kilauea volcano, Hawaii, increased, with heightened ash production from the summit commencing on May 17. Volcanic ash can scavenge volatile components from volcanic plumes, resulting in the deposition of potentially harmful elements during ash fallout. Leaching of these species (e.g., by rainfall or in water catchment systems) can have implications for...

Coral skeleton δ15N as a tracer of historic nutrient loading to a coral reef in Maui, Hawaii Coral skeleton δ15N as a tracer of historic nutrient loading to a coral reef in Maui, Hawaii
Excess nutrient loading to nearshore environments has been linked to declining water quality and ecosystem health. Macro-algal blooms, eutrophication, and reduction in coral cover have been observed in West Maui, Hawaii, and linked to nutrient inputs from coastal submarine groundwater seeps. Here, we present a forty-year record of nitrogen isotopes (δ15N) of intra-crystalline coral...
