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.

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas. While flood management strategies are being implemented in urban areas, less is known about how tidal flooding, and associated inundation into surface and groundwater, might influence watershed dynamics and the native animals that depend on estuarine environments where freshwater meets the sea. Efforts for biocultural restoration of ecosystem...

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 was collected to estimate coastal exposure and vulnerability index for rapid decision-making. The dataset identifies coastal regions exposed to climatic changes and prioritizing beaches for restoration goals using various models and indices including: the output of SWAN (Simulating waves nearshore) model, the geomorphology of the coastline of the State of Hawaiʻi based on Environmental Sensitivity Index, an index for identifying coastal regions protected by attenuation capabilities of corals from climatic forcings, the use of linking bathymetry (Multibeam Bathymetry Synthesis - UH SOEST) and Digital Elevation Model (NOAA - IfSAR) of topography for the State of Hawaiʻi, the status of coral reefs using the...
