The critical zone thus includes all resources critical to life. This paper evaluates chemical and physical processes in the critical zone, specifically in soils, streams, and groundwater. Our work suggests the important influence of groundwater-surface water interactions on mountain streams with an emphasis on the transport of water and solutes.

Relating spatial and temporal scales of climate and ocean variability to survival of Paciﬁc Northwest Chinook salmon (Oncorhynchus tshawytscha) RISHI SHARMA,1* LUIS A. VE´LEZ-ESPINO,2 ALEX C. WERTHEIMER,3 NATHAN MANTUA4 AND ROBERT C. FRANCIS4 1Columbia River Inter-Tribal Fish Commission, NE Oregon St, Suite , Portland, OR , U.S.A. Spatial variability (both SDspace and CVspace) decreased with movement duration, while temporal variability (both SDtime and CVtime) increased with movement duration. We found strong negative correlations between spatial and temporal variabilities over variations in movement duration, whether the variability examined was absolute or by: 4.
Regarding vegetation response to rainfall variability, two main areas were identified where differences in LSP metrics between wet and dry years were larger than the average. The first one was a zone within the humid to semi‐arid transition belt, where NDVI maximum, NDVI amplitude and NDVI integral showed higher values during wet by: 2. teaching and writing about spatial, temporal, and spatial-temporal data analysis. It was only after we became aware of material described in Lindgren et al. () that we realised that GLMs and GLMMs, and all their zero-inflated cousins and smoothing cousins, can be extended to spatial, temporal, and spatial-temporal Size: KB.

Spatial variability in the hyporheic zone refugium of temporary rivers Article (PDF Available) in Aquatic Sciences 73(4) November with Reads How we measure 'reads'. The spatiotemporal variability of hyporheic fluxes is not well understood over several temporal scales and consequently, we studied their spatial and temporal variation over a pool-riffle-pool.
We documented spatial and temporal variability of hyporheic zone geochemistry in response to a large‐scale storm event, Tropical Storm Irene (August ), across a pool–riffle–pool sequence along Chittenango Creek in Chittenango, NY, by: This study examined spatial variability in the refugial capacity of the hyporheic zone in two groundwater-dominated streams in which flow permanence varied over small areas.
Two non-insect taxa, Gammarus pulex and Polycelis spp. were common to both streams and were investigated in detail. Hydrological conditions in both streams comprised a four Cited by: title = "Temporal and spatial response of hyporheic zone geochemistry to a storm event", abstract = "Although there has been recent focus on understanding spatial variability in hyporheic zone geochemistry across different morphological units under baseflow conditions, less attention has been paid to temporal responses of hyporheic zone Cited by: Temporal variability speaks to the variability of time.
Time is not a constant. We often think of time as being constant because we measure it with very accurate clocks, and we live our lives in. The Hyporheic zone has a distinct and varied ecology, with the zones physical and geochemical properties and abiotic conditions all affecting the ecological communities and locations within the zone.
Due to the varying conditions of the hyporheic zone to the surface waters there is the potential for the hyporheic zone to act as a refuge for. Spatial and Temporal Variability of Soil Physical and Hydraulic Properties Research Findings, Reports, and Publications for this Project Site-specific farming assumes that fields used for agricultural production are not uniform but rather exhibit large spatial variability in their properties.
Spatial and temporal variation in deep soil water content at a watershed scale have not yet been characterized adequately due to the lack of deep soil water data. Deep soil–water storage (SWS) up to a depth of 5 m (n = 73) was measured at 19 sampling occasions at the LaoYeManQu watershed on the Chinese Loess Plateau (CLP).Cited by: 4.
Monthly acceleration potential (AP) relative to dbar is calculated for the isopycnal surface kg m −3 from January to December to investigate the spatial and temporal variability of the California Current.
A composite analysis was conducted to obtain the total-time mean AP field and the climatological monthly mean AP Author: Peter C. Chu, Tetyana Margolina, DyAnna Rodriguez, Chenwu Fan, Leonid M. Ivanov. To illustrate this interaction, we constructed two-way variability tables in which spatial (habitat, reach or zone, system, intersystem) and temporal (within a day, within a season, within a year, year to year) scales were ordered on separate axes, and examples of concurrent spatial and temporal variability were entered at the intersects of the Cited by: The spatial-temporal variability of NH3 at the study sites That the relationship between the hourly mean NH3 concentration and relative humidity and temperature was not significant Measurements at sites such as the Burnaby South High School where the average monthly NH3 concentrations for the year and ranged between and ppb.

The northern part of Hindukush Mountains has a perplexing environment due to the influence of adjacent mountains of Himalaya, Karakoram, and Tibetan Plateau. Although reliable evidences of climate change are available; however, a clear knowledge of snow cover dynamics in the context of climate change is missing for this region.

Introduction. The Amazon in South America and equatorial Africa and Indonesia form the three main centers of action of deep convection around the global tropical belt .In particular, the Amazon exhibits a high spatial and temporal variability of rainfall with a very pronounced seasonality, such that the rainy and dry seasons typically occur during the months of summer/autumn and winter Cited by: 4.
Temporal is a fancy term referring to comparisons made with respect to the passage of time. If a process is temporally extended, it means that it happens over a period of time. If two events differ temporally, they happen at different points in ti.

Three sites are in Nunavut (Alert, Iqaluit, and Baker Lake), two in the Northwest Territories (Table Mountain and Wrigley), and four in the Yukon. Abstract: The spatial-temporal variability of drought occurrence over Bulgaria is characterized based on long-term records (–) of Meteosat information and the SVAT model-derived soil moisture availability index (referred to root zone depth, SMAI).
Land surface temperature according to theAuthor: Julia Stoyanova, Christo Georgiev, Plamen Neytchev, Andrey Kulishev.Spatial–temporal reasoning is an area of artificial intelligence which draws from the fields of computer science, cognitive science, and cognitive theoretic goal—on the cognitive side—involves representing and reasoning spatial-temporal knowledge in mind.Expansion and contraction of the hyporheic zone due to temporal hydrologic changes between stream and riparian aquifer influence the biogeochemical cycling capacity of streams.
Theoretical studies have quantified the control of groundwater discharge on the depth of the hyporheic zone; however, observations of temporal groundwater controls are Cited by:
