Volcanic ash geochemistry and leachate analyses from the 2008 opening of Halemaʻumaʻu crater, Kīlauea Volcano, Hawaiʻi Volcanic ash geochemistry and leachate analyses from the 2008 opening of Halemaʻumaʻu crater, Kīlauea Volcano, Hawaiʻi
On March 19, 2008, an explosive eruption occurred at the summit of Kīlauea Volcano for the first time since 1924. This event marked the beginning of a continuous summit eruption that lasted until the 2018 Kīlauea lower East Rift Zone eruption (Neal and others, 2019). The March 19 explosive eruption excavated a crater approximately 35 meters wide and scattered volcanic tephra over a 30...
Archive of Bank Stability and Toe Erosion Model (BSTEM) Simulations of Caulks Creek, Wildwood, Missour Archive of Bank Stability and Toe Erosion Model (BSTEM) Simulations of Caulks Creek, Wildwood, Missour
The Bank Stability and Toe Erosion Model (BSTEM) version 3.3.1 (Ursic and Langendoen, 2021) was used to predict bank retreat at five locations along Caulks Creek, Wildwood, Missouri, for a selection of design storm scenarios. BSTEM is a macro-enabled Excel spreadsheet (.xlsm file) that simulates the retreat of a bank profile due to a combination of fluvial and geotechnical processes...
High resolution double-difference relocations of earthquakes in and offshore Puerto Rico and Virgin Islands during the deployment of ocean bottom seismometers from mid-2015 to mid-2016 High resolution double-difference relocations of earthquakes in and offshore Puerto Rico and Virgin Islands during the deployment of ocean bottom seismometers from mid-2015 to mid-2016
Puerto Rico is a Caribbean Island with a population of about 3.2 million people who are exposed to natural hazards including earthquakes and submarine landslides that can generate tsunamis. Previous work has shown seismicity offshore Puerto Rico especially between the coastline and the Puerto Rico Trench north of the island. The Puerto Rico Seismic Network maintains the local seismic...
Highway-Runoff Database (HRDB) Version 1.2.0 Highway-Runoff Database (HRDB) Version 1.2.0
The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation's receiving waters...
Occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA Occupancy surveys near Marbled Murrelet (Brachyramphus marmoratus) nest sites and random locations between 2018 and 2022 along the central Oregon coast, USA
There are four data tables (csv documents) provided here which are formatted according to tidy data principles. We identified sites centered on known murrelet nest trees (nest sites) and on randomly selected trees (control sites) and the first table contains variables that vary at the site level. Each site had up to three stations where occupancy surveys were collected, so the second...
Mean annual water-budget components for Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, and the Island of Hawaiʻi for a set of recent and future climate conditions, and 2020 land cover Mean annual water-budget components for Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, and the Island of Hawaiʻi for a set of recent and future climate conditions, and 2020 land cover
The shapefiles in this dataset represent the spatial distribution of mean annual water-budget components, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, and the Island of Hawaiʻi, for a set of recent and future climate conditions, and 2020 land cover. The four main climate scenarios used in the water-budget analyses include a reference climate scenario representative of recent...
