Passive seismic imaging of near vertical structures around the SAFOD site, California, jointly using scattered P and SH waves
<p>1, The P and S velocity model are in the velocity folder which written by binary format (float). The size of the velocity model is 101*101*56(Nx Ny Nz) with a 200 meter grid. The upleft corner is (-10km -10km -1km). The unit of the velocity is km/s.</p> <p>2, The stations and events are in the geometry folder:</p> <p>the format of the file is</p> <p>Number of the stations/events</p> <p>Name of the stations/events, X(km), Y(km), Z(km). </p> <p>the origin of the coordinates system is the bole hole SAFOD, and the local coordinates was rotated by 40.5 degree.</p> <p>The name of the events was the origin time (precise to the minute) of the events.</p> <p>For example:</p> <p>the 1227042400 indicates that </p> <p>Year JulianDay hour minute second</p> <p>2001 227 04 24 00</p> <p>You can get the details and download the waveform at the website https://www.fdsn.org/networks/detail/XN_2000/ and https://www.fdsn.org/networks/detail/BP/</p> <p>2.1) the "events_3.7km_56" includes 56 events that was at the same depth~3.7km, The common station (The TANK Station) gather was shown in figure 6. </p> <p>2.2) "events_all" indicates 560 events that shown in Figure 4, and there are about 10 events not in the SAF, we did not use them, the "events_rm_outlier" are the 546 events we lastly used.</p> <p>2.3) "stations.dat.65" is the combination of the PASO and HRSN that in 20km square area as shown in Figure1.</p>
Data from: The effect of DNA degradation bias in passive sampling devices on metabarcoding studies of arthropod communities and their associated microbiota
PCR amplification bias is a well-known problem in metagenomic analysis of arthropod communities. In contrast, variation of DNA degradation rates is a largely neglected source of bias. Differential degradation of DNA molecules could cause underrepresentation of taxa in a community sequencing sample. Arthropods are often collected by passive sampling devices, like malaise traps. Specimens in such a trap are exposed to varying periods of suboptimal storage and possibly different rates of DNA degradation. Degradation bias could thus be a significant issue, skewing diversity estimates. Here, we estimate the effect of differential DNA degradation on the recovery of community diversity of Hawaiian arthropods and their associated microbiota. We use a simple DNA size selection protocol to test for degradation bias in mock communities, as well as passively collected samples from actual Malaise traps. We compare the effect of DNA degradation to that of varying PCR conditions, including primer choice, annealing temperature and cycle number. Our results show that DNA degradation does indeed bias community analyses. However, the effect of this bias is of minor importance compared to that induced by changes in PCR conditions. Analyses of the macro and microbiome from passively collected arthropod samples are thus well worth pursuing.

Gunshot sound files and spectrogram images from passive acoustic monitoring data in Vietnam.
<h3><strong>Introduction</strong></h3> <p>This dataset was created to support benchmarking of automated gunshot detection models using 'torch for R'. The data includes recordings collected from Chu Mom Ray National Park in Vietnam combined with an open dataset of gunshots from Belize (Katsis et al. 2022). The dataset is organized into several folders containing .jpg images and their corresponding .wav audio clips. </p> <h3>Data Summary</h3> <p>The dataset is divided into three main categories based on the region and use case:</p> <ol> <li>imagesvietnamunbalanced: Contains spectrogram images and audio data collected from Chu Mom Ray National Park in Vietnam. These data are used for training and evaluating automated gunshot detection models.</li> <li>imagesvietnam_belize: Includes spectrogram images and audio data from both Vietnam and Belize. The data in this folder is used for benchmarking model performance across different geographical regions.</li> <li>testdatacombined: Separate test data to evaluate performance with a large number of noise clips, representing real-world automated detection scenarios.</li> </ol> <p>Each .jpg image in these directories is associated with a .wav file representing a corresponding audio clip. The .wav files were recorded using passive acoustic monitoring and clips were isolated using manual annotations in Raven Pro Software.</p> <p>If used please cite: </p> <p>Vu, T. T., Phan, D.
