The data document the results of several microbe bioassays performed by the USGS on Phragmites australis plants, including those performed on mature leaves, seedlings, and dead leaf tissues exploration of the literature to find accounts of microbes associated with Phragmites worldwide. For the bioassays, we prepared 162 pure cultures isolated from Phragmites plants in North America along the east coast, Florida, the Gulf of Mexico, and the Great Lakes area, 125 of which were from a previous study, and 38 represent new collections. The DNA sequences used to identify the 37 new collections are included. Microbes were isolated from plants collected from 2015-2018. We performed assays using both North American plant...
The Critical Minerals in Archived Mine Samples Database (CMDB) contains chemistry and geologic information for historic ore and ore-related rock samples from mineral deposits in the United States. In addition, the database contains samples from archetypal deposits from 27 other countries in North America, South America, Asia, Africa and Europe. Samples were obtained from archived ore collections under the U.S. Geological Survey's project titled "Quick Assessment of Rare and Critical Metals in Ore Deposits: A National Assessment" (2008 to 2013) in an effort to begin an assessment of the Nations' previously mined ore deposits for critical minerals. Mineralized and altered rock samples were provided by the Colorado...

The aim of this study was to determine if Arase dam gate removal and flushing elevated concentrations of any trace elements in Kuma River and Yatsushiro Bay sediments or caused riverine environmental change. The Arase dam gate on the Kuma River was opened in April 2010. Surface and bottom sediments were compared using 10-cm-long cores (2011) and two grain size fractions. Surface sediment data from 2002, 2012, and 2013 from the Kuma River and Yatsushiro Bay were also compared. The sediments were analyzed using XRF for 23 elements, and the grain size analysis was done. The short core surface and bottom sediments do not show major chemical changes, and therefore, may not represent post-and pre-dam sediments. Results...

This inventory was originally created by Yagi and others (2009) describing the landslides triggered by the M6.9 Eastern Honshu, Japan earthquake that occurred on 2008-06-13 at 23:43:45 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory also could be associated with other earthquakes such as aftershocks or triggered events. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data and associated metadata were not acquired by the U.S. Geological...

For more than 25 years, the U.S. Geological Survey Gas Hydrates Project has compiled and maintained an internal database of locations where the existence of gas hydrate has been confirmed or inferred in research studies. The existence of gas hydrate was considered confirmed when gas hydrate was recovered by researchers or videotaped from a vehicle (such as a submersible or remotely operated vehicle) near the sea floor. The existence of gas hydrate was considered inferred when seismic data, borehole logs, or certain geochemical characteristics match anomalies known to characterize gas hydrate. This data release provides a text description of the region, geographic coordinates, and the citation for the published reference...
This database is the result of an extensive literature search aimed at identifying documents relevant to the emerging field of dam removal science. In total the database contains 296 citations that contain empirical monitoring information associated with 207 different dam removals across the United States and abroad. Data includes publications through 2020 and supplemented with the U.S. Army Corps of Engineers National Inventory of Dams database, U.S. Geological Survey National Water Information System and aerial photos to estimate locations when coordinates were not provided. Publications were located using the Web of Science, Google Scholar, and Clearinghouse for Dam Removal Information.

The Sea Surface Temperature (SST) data of the nearshore region of the North Pacific show temperature ranges in degrees C using points whose locations correspond to the centroids of AVHRR Pathfinder version 5 monthly, global, 4 km data set (PFSST V50). The pathfinder rasters are available from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. The data points in this dataset lie within a 20 km buffer from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) coastline. The GSHHS vector data are available from the National Geophysical Data Center (NGDC). Furthermore, each point in the SST dataset is categorized by the ecoregion in which it is located. This...
This inventory was originally reated by Sekiguchi and Sato (2006) describing the landslides triggered by a sequence of earthquakes, with the largest being the M 6.6 Niigata-Chuetsu, Japan earthquake that occurred on 23 October 2004 at 08:56:00 UTC. Care should be taken when comparing with other inventories because different authors use different mapping techniques. This inventory includes landslides triggered by a sequence of earthquakes rather than a single mainshock. Please check the author methods summary and the original data source for more information on these details and to confirm the viability of this inventory for your specific use. With the exception of the data from USGS sources, the inventory data...

This paper analyzes the socio-cultural, political and economic conditions prevalent during the inception of nuclear power programs in Japan and South Korea in order to identify commonalities which support nuclear power program expansion. The study identifies six factors as having a clear influence on supporting nuclear power development: (1) strong state involvement in guiding economic development; (2) centralization of national energy policymaking and planning; (3) campaigns to link technological progress with national revitalization; (4) influence of technocratic ideology on policy decisions; (5) subordination of challenges to political authority, and (6) low levels of civic activism. The paper postulates that...
The Aratozawa Dam landslide in Japan, was triggered by the 7.2 magnitude Iwate-Miyagi-Nariku earthquake which occurred on 14 June 2008. The landslide at the Aratozawa Dam in Kurihara measures over 1km in length and is 0.8 km wide. The landslide body mass is around 6700 million cubic meters and the amount of displacement was around 300 meters in the main section. The landslide was translational in nature and the geology comprises hard volcanic rocks overlying soft Tertiary sediments.

Over the past several years, the State of Washington has invested substantial time and energy to streamline the environmental regulatory and permit process. The creation of the Multi-Agency Permitting Team (MAP team) pilot is one such strategic investment. The concept is based on the idea that an interagency team composed of diverse disciplines, located within one office, will experience enhanced communication, coordination, and higher-quality, more timely permit decisions. Currently, the MAP team consists of staff from five government agencies: the U.S. Army Corps of Engineers, Washington State Department of Ecology, Washington State Department of Fish and Wildlife, Washington State Department of transportation,...

Geologic samples including hand samples and thin sections that were collected between 1955 and 1956 by Helen Foster and Harold May during the geologic mapping of the Pacific islands of Ryukyu that extend southwest from Japan. Most of the samples were collected from Ishigaki Island and were analyzed to interpret the geology of Ishigaki in USGS Professional Paper 399-A. Ruth Deike of the USGS Geologic Division began an inventory of the samples and thin sections in 2007, but the samples were soon after sent to the Core Research Center for storage. The inventory of the samples was completed by Chris Stuckey of the Core Research Center with a total of 807 hand samples and thin sections. Supplementary data has been added...
