Network Attributes for the Hi Res National Hydrography Dataset (NHD) based initial 3D Hydrography Program Network DISCLAIMER "These data are preliminary or provisional and are subject to revision. They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data." See Full Metadata Here This dataset contains the initial 3D Hydrography Program (3DHP) flow network based on the final High Resolution National Hydrography Dataset (NHD) [data] [documentation] and a set of mainstem rivers [data] built on the Medium resolution NHDPlus Version 2 (NHDPlusV2). Two key pieces of... Categories: Data, Data Release - In Progress; Tags: Conterminous US, environment Data Release: Regional Moment Tensor Solutions The development and deployment of digital broadband seismographs provides the data required to rapidly assess earthquake size, determine source parameters and better characterize ground motions affecting earthquake hazard. The focus of regional moment tensor analysis is to estimate the moment magnitude, faulting parameters and source depth of earthquakes that are too small to be recorded teleseismically. Thus they have the potential of extending the earthquake catalog to magnitudes less than about M4-4.5. This data distribution provides the details required to critically review the resulting catalog, e.g., the waveforms used, processing parameters and velocity model. In addition the issue of the correct local...

This includes the station, location and arrivaltime input files to the tomography and the output relocations and resulting P- and S-wave images. The output results are relocated seismicity, tomographic velocity models (P and S-wave). We included a file containing coordinate information (latitude, longitude, elevation) of all California seismic stations, some of which are used in this study. Note that we did not use the S-wave imaging results in the study of Furlong et al. (2024)--see reference below. Checkerboard reconstructions are also provide, which includes the input and output models.... Categories: Data Release - In Progress Massachusetts River Herring Daily Counts and Environmental data The timing of biological events in plants and animals, such as migration and reproduction, is shifting due to climate change. Anadromous fishes are particularly susceptible to these shifts, as they are subject to strong seasonal cycles when transitioning between marine and freshwater habitats to spawn. We used linear models to determine the extent of phenological shifts in adult alewife (Alosa pseudoharengus) as they migrated from ocean to freshwater environments during spring to spawn at 12 sites along the northeast U.S. We also evaluated broad-scale oceanic and atmospheric drivers that trigger their movements from offshore to inland habitats including sea surface temperature (SST), North Atlantic Oscillation index,...
