Seventy six parent and alkylated polycyclic aromatic compounds, including polycyclic aromatic hydrocarbons (PAHs), were quantified in watershed and reef sediment from Olowalu, Maui, in February 2022 to explore urban and wildfire effects. Sample locations and total organic carbon contents (OC) are available in the accompanying file OlowaluWatershedReef2022_compositions.csv.

Fine-sediment elemental chemistry and short-lived cosmogenic radionuclides (Beryllium-7, Cesium-137, and Lead-210) were quantified to describe land-based sediment sources and runoff to Olowalu Reef in February 2022. Charcoal counts, total organic carbon contents, and 76 urban- and wildfire-associated contaminants called polycyclic aromatic hydrocarbons (PAHs) were quantified to explore urban and wildfire effects in watersheds above Olowalu Reef and in reef sediment. Sampling occurred approximately two months after winter flooding and one month after tsunamigenic waves impinged on the Maui shore from the eruption of Hunga-Tonga volcano in the South Pacific. The USGS Coastal and Marine Hazards and Resources Program...

This data release contains a comma-delimited ascii file of 25 discrete discharge measurements made at sites along selected reaches of Waikapū Stream, Maui, Hawai'i on October 16, 2018 and May 7, 2019. These discrete discharge measurements form what is commonly referred to as a “seepage run.” The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during fair-weather, low-flow conditions, generally characterized by negligible direct runoff within the reach. The measurements can be used to characterize the net seepage of water into (water gain) or out of (water loss) the stream channel between measurement sites provided that the measurements were made during stable, nonchanging...
