Model Archive Summary for Turbidity Derived Suspended-Sediment Concentrations at 11312672 Victoria Canal Near Byron, Ca Model Archive Summary for Turbidity Derived Suspended-Sediment Concentrations at 11312672 Victoria Canal Near Byron, Ca
Continuous 15-minute time-series suspended-sediment concentration (SSC) data computed from instream turbidity data. Turbidity data is managed by California Department of Water Resources (CDWR) using a YSI-6-series multi-parameter water quality sonde. Complete methods for turbidity data collection are described in attached methods document.

Survival of early instar mayflies (Neocloeon triangulifer) exposed to mixtures of major ion salts Survival of early instar mayflies (Neocloeon triangulifer) exposed to mixtures of major ion salts
This data set consists of 96-hour survival of the mayfly Neocloeon triangulifer exposed to a variety of major ion (sodium, potassium, calcium, magnesium, chloride, sulfate, bicarbonate) single salts, binary, and trinary mixtures, gluconate salts, and the organic molecule D-mannitol. Mayflies were less than 24-hours old at the beginning of tests. Mixtures consisted of pairs with either...
Stream Characteristics and Species Data for Foothill Yellow-legged Frogs in Southern San Benito and Western Fresno Counties, California, 2019-2021 Stream Characteristics and Species Data for Foothill Yellow-legged Frogs in Southern San Benito and Western Fresno Counties, California, 2019-2021
These data contain information on stream characteristics (intermittency and temperature), vegetation (canopy and algal cover), amphibian, reptile, and fish observations, and pathogen (amphibian chytrid fungus, Batrachochytrium dendrobatidis) prevalence, all of which are relevant for the suitability of streams in Pinnacles National Park for the reintroduction of foothill yellow-legged...
