Map showing lava flows in the southeast part of the Memnonia Quadrangle of Mars Map showing lava flows in the southeast part of the Memnonia Quadrangle of Mars

The Systematic mapping of lava flow units in the Tharsis region has been compiled into a series of 16 maps at 1:2,000,000 scale. This work provides information on the sources and areal extent of the lava flows, on their eruptive sequences and relative ages, and on relations between the flows and geologic structure in the largest, most active tectonic and volcanic province on Mars. Some...

Nutrient and Sediment Concentrations, Loads, and Yields in the Upper Macoupin Creek Watershed, Water Years 2018–2021 Nutrient and Sediment Concentrations, Loads, and Yields in the Upper Macoupin Creek Watershed, Water Years 2018–2021

This data release includes estimates of annual and daily concentrations and fluxes for nitrate plus nitrite, total phosphorus, and suspended sediment for two sites in the Upper Macoupin Creek Basin watershed (UMCB) produced using the Weighted Regressions on Time, Discharge, and Season -- Kalman Filter (WRTDS-K; Zhang and Hirsch, 2019) model in the Exploration of and Graphics for RivEr...
