Abstract Seasonal snowmelt from the Wasatch Mountains of northern Utah, USA, is a primary control on water availability for metropolitan Front, surrounding agricultural valleys, and Great Salt Lake (GSL). Prolonged drought, increased evaporation due to warming temperatures, sustained domestic consumption have caused GSL levels reach record low stands in 2021 2022, resulting exposure dry lakebed sediment. When dust emitted deposited adjacent snowpack, snow darkened, accelerated. Regular...
Forsterite (Fo)-rich olivine compositions from San Carlos (Arizona, SW USA) are commonly used as starting material in experimental petrology. In comparison to the reference USNM 111312/444, it has been shown that major element variability of non-USNM is significant. We complement characterization compositional with new data, including minor and trace analyses. High precision analyses reveal selected elements (e.g., ~6% NiO, ~10% MnO, ~16% CaO, relative) ~75% Cr, ~120% Cu, ~160% P Ti, present...
Abstract Seasonal snowpacks in mountain drainages of the Great Salt Lake Basin (GSLB), western United States, are primary surface water supply to regional agriculture, metropolitan Wasatch Front, and terminal Lake. Spring dust emissions from eastern result a dust‐darkened GSLB snowpack, locally accelerating snowmelt relative dust‐free conditions. Such acceleration has been linked streamflow forecasting errors adjacent Colorado River Basin, but snow darkening impacts within largely...
Abstract In the mountainous headwaters of Colorado River episodic dust deposition from adjacent arid and disturbed landscapes darkens snow accelerates snowmelt, impacting basin hydrology. Patterns impacts across heterogenous landscape cannot be inferred current in situ observations. To fill this gap daily remotely sensed retrievals radiative forcing contribution to melt were analyzed over MODIS period record (2001–2023) quantify spatiotemporal darkening. Each season magnitudes lowest early...
Mantle heterogeneity has a first-order control on the petrological and geochemical differences of erupted mafic lavas worldwide. Because their contrasted distributions between mantle phases, First Row Transition Elements (FRTEs) have been considered potential lithological tracers. Using combination published data natural experimental samples new high-precision analyses variety pyroxenite samples, we investigate parameters that FRTE partition (Ds) exchange (KDs) coefficients common minerals....
Seasonal mountain snowmelt is an important contributor to surface water resources and groundwater recharge in the midlatitudes, making forecasting of timing duration critical for accurate hydrologic prediction. Net solar radiation, controlled primarily by snow albedo, main driver most covered environments. Lowering albedo from episodic dust deposition has been shown be control on patterns Rocky Mountains Western United States. Here, we compare contrast trends impacted over previous two...
First Row Transition Elements (FRTEs) have been identified as potential petrogenetic indicators because of their contrasted partitioning behaviors between the solid mantle phases.Using a combination published data on natural and experimental samples new high precision analyses (high-current microprobe LA-ICP-MS analyses), we investigate various parameters that control FRTE common minerals.Our results show pyroxenites (found in ophiolites ultramafic massifs) peridotites share same...
