Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Hawaiʻi Volcanoes National Park Effects of Felling and Tarping Trees on ROD Viability and Ambrosia Beetle Activity 2022-2023 Hawaiʻi Volcanoes National Park Effects of Felling and Tarping Trees on ROD Viability and Ambrosia Beetle Activity 2022-2023
Felling and tarping is a common management strategy for ʻōhiʻa lehua trees (Metrosideros polymorpha) infected with rapid ʻōhiʻa death (ROD) caused by Ceratocystis lukuohia and Ceratocystis huliohia fungal pathogens and spread via ambrosia beetles (Coleoptera: Curculionidae). In order to understand how tarping may decrease fungal viability or the spread of viable beetle frass, this study...
Island of Hawai'i Ambrosia Beetle Trapping Data and Locations of Suspected Ceratocystis-positive ʻōhiʻa at Two Sites, 2021-2022 Island of Hawai'i Ambrosia Beetle Trapping Data and Locations of Suspected Ceratocystis-positive ʻōhiʻa at Two Sites, 2021-2022
This data release includes data and metadata documenting 1) ambrosia beetle (Coleoptera: Curculionidae) species caught in multi-panel traps within ʻōhiʻa lehua (Metrosideros polymorpha) dominated forests in Hawaiʻi Volcanoes National Park as well as results from culturing Ceratocystis lukuohia or Ceratocystis huliohia, the fungi that cause rapid ʻōhiʻa death (ROD), from these traps, 2)...
Chub whole body calorimetry, feeding trial ration, and chironomid weights to develop inputs for a bioenergetics community model Chub whole body calorimetry, feeding trial ration, and chironomid weights to develop inputs for a bioenergetics community model
A series of laboratory studies were conducted to understand Sicklefin and Shoal Chub feeding rates and maximum ration. Data included determination of Chironomid weight, estimated by taking weights and counts of approximately 5 grams of laboratory cultured chironomids. Chub maximum ration was determined by finding the feeding rate of dry commercial fish food that thar resulted in complete
Data release for mortality events in Yuma myotis (Myotis yumanensis) due to white-nose syndrome in Washington, USA, 2020-2024 Data release for mortality events in Yuma myotis (Myotis yumanensis) due to white-nose syndrome in Washington, USA, 2020-2024
The impacts of white-nose syndrome (WNS) on many bat species in eastern North America have been well-documented due to the length of time that the causative agent, Pseudogymnoascus destructans (Pd), has been present and the ability to monitor bat hibernacula in that region. However, the disease outcomes for bat species in western North America are less known because of the more recent...
Oceanographic Time Series Measurements Collected at Dorado, Puerto Rico Oceanographic Time Series Measurements Collected at Dorado, Puerto Rico
The U.S. Geological Survey (USGS) deployed thirteen pressure loggers (RBR) to measure water levels and wave conditions on a reef-lined coast in Dorado, Puerto Rico. These loggers were positioned along a cross-shore transect that extends 1.8 kilometers from the coast (on the forereef, reef crest, and reef flat) and at various points within the reef embayment. Initial deployments began in...
Distance to the nearest stream by stream order for selected watersheds in the United States Distance to the nearest stream by stream order for selected watersheds in the United States
Accurate representation of stream networks at various scales in a hydrogeologic system is integral to modeling groundwater-stream interactions at the continental scale. To assess the accurate representation of stream networks, the distance of a point on the land surface to the nearest stream (DS) has been calculated. DS was calculated from the 30-meter Multi Order Hydrologic Postion...
