Fish Community and habitat assessment in the Sandusky River, OH, April 2021 through October 2021 Data includes fish abundance and habitat data collected at ten sites in the Sandusky River, OH. Fish were collected using two 3.67 m long hoop nets with an initial hoop diameter of 0.91 m. Nets were set perpendicular to the current, opening toward the shoreline. Nets were set for approximately 24 hours and catch rates for each set were defined as the number of fish caught in the two hoop nets per 24-hour sampling period. Fish were identified to species, measured for total length (mm), and released. Water quality was taken daily at each site at approximately the same time of day with a YSI Exo2 multiparameter sonde. Physical habitat data was recorded at the start of each trial. Vegetation coverage was characterized...

This dataset contains more than 23,908earthquakes in 346 well distributed clusters. Currently there are more than 4M arrival times with the majority being the Pg, Pn, P, Sg, Sn and S phases. The term “calibrated” refers to the property that the hypocenters are minimally biased by unknown Earth structure and that the uncertainties are meaningful. Uncertainties are calculated using empirically determined variability of the arrival time data itself, specific to each calibrated cluster of hypocenters. The data are carefully processed...
