[1] In summer on the shallow New England continental shelf, near the coast the water temperature is much cooler than the observed surface heat flux suggests. Using depth‐integrated heat budgets in 12 and 27 m water depth calculated from observed surface heat flux, water temperature, and velocity, we demonstrate that on time scales of weeks to months the water is persistently cooled due to a mea...

This paper focuses on the integration of basin sediment transport with a physically-based hydrological model that links the water budget model WaSiM (Water Simulation Model) to the erosion model AGNPS__5. The results of the water budget simulation are then incorporated into the AGNPS_5 model to calculate sediment transport. The surface runoff calculated in WaSiM replaces the SCS curve number ru...

Evapotranspiration (ET) is a key component of the hydrologic cycle, accounting for ~70% of precipitation in the conterminous U.S. (CONUS), but it has been a challenge to predict accurately across different spatio-temporal scales. The increasing availability of remotely sensed data has led to significant advances in the frequency and spatial resolution of ET estimates, derived from energy balanc...

The secondary mineral budget on Earth is dominated by clay minerals, Al-hydroxides, and Fe-oxides, which are formed under the moderate pH, high water-to-rock ratio conditions typical of Earth's near-surface environment. In contrast, geochemical analyses of rocks and soils from landed missions to Mars indicate that secondary mineralogy is dominated by Mg (±Fe, Ca)-sulfates and Feoxides. This dis...

We estimated the mass budget for mercury (Hg) seasonally deposited into the Florida Everglades and investigated seasonality of Hg cycling by analyzing data obtained for water, soil, flocculent detrital material (floc), periphyton, and mosquitofish collected throughout the Everglades freshwater marshes in the 2005 dry and wet seasons. Higher wet season total Hg (THg) in soil, floc, and periphyto...

[1] Estuarine near‐surface turbulence is important for transport, mixing, and air‐water exchanges of many important constituents but has rarely been studied in detail. Here, we analyze a unique set of estuarine observations of in situ atmospheric and full water column measurements, estimated air‐sea exchanges, and acoustic measurements of several terms in the turbulent kinetic energy (TKE) budg...

The water budget in clay shale terrain is controlled by a complex interaction between the vertisol soil layer, the underlying fractured rock, land use, topography, and seasonal trends in rainfall and evapotranspiration. Rainfall, runoff, lateral flow, soil moisture, and groundwater levels were monitored over an annual recharge cycle. Four phases of soil–aquifer response were noted over the stud...

This study documents the Earth radiation budget as simulated by the latest version of the National Center for Atmospheric Research community climate model (CCM2). The validation of the simulated Earth radiation budget is carried out through comparison with Earth Radiation Budget Experiment (ERBE) data. The study also documents the new cloud parameterization employed by CCM2. In general, the rad...

One advantage of dual-polarization radars is the ability to differentiate between water and ice phases in storms. The application of difference reflectivity (ZDP) in the analysis of mixed-phase precipitation is presented. Here, ZDP analysis is used to obtain the fraction of water and ice in mixed-phase precipitation. The techniques developed are applied to data collected on 9 August 1991 during...

Today, a 34m global equivalent water layer (GEL) lies in the Martian polar-layered deposits and shallow ground ice. During the Amazonian, 3m was outgassed, and 31m was lost to space and to the surface, leaving 62m at the end of Hesperian. During the Hesperian, volcanic outgassing added 5m, 7m was lost, and 40m GEL of groundwater was added to form outflow channels, leaving 24m carryover of surfa...
