Streambed and suspended sediment data from streams in western Montana from 2018 Streambed and suspended sediment data from streams in western Montana from 2018

This data release contains streambed sediment data, suspended sediment data, and stream stage data from tributary streams in Western Montana. These datasets were created to assess the linkages between unpaved roads and instream sediment distributions. Surveys were collected in tributaries and rivers within the Clearwater River and Swan River basins in Montana. Site locations were...

Pathological findings by fixative time and formulation for Porites evermanni and Montipora capitata Pathological findings by fixative time and formulation for Porites evermanni and Montipora capitata

Collections for histopathology in corals require holding of samples in seawater for a time before they are fixed for histopathology processing. This could adversely affect interpretation of morphologic changes during histopathology examinations. We evaluated microscopic morphology of Porites evermanni and Montipora capitata, held (0-120 min) in seawater prior to fixation in Z-Fix...
