Summer sea surface temperature variability off Vancouver Island from satellite data, 1984-1991
… High Resolution Radiometer (AVHRR) Sea Surface Temperature (SST) data over eight summers (1984-1991) were used to analyze the summer SST patterns of variability off the west coast of Vancouver Island. Empirical Orthogonal Function (EOF) analysis of the spatial variance for 133 nearly cloud-free …

Upwelling dynamics off Monterey Bay : heat flux and temperature variability, and their sensitivities
… already existed. Using the thermal energy (temperature), salinity and momentum (velocity) conservation equations, full ocean fields in the region as well as both control volume (flux) balances and local differential term-by-term balances for the upwelling event events were computed. The …

Consequences of short-term water temperature variability to fish: Current and future climate change impacts
<p>Water temperature has a profound influence on aquatic ectotherms by affecting all aspects of biological organization; from chemical and molecular functioning to whole-organism and population-level impacts. Natural processes and anthropogenic activities can create conditions where temperatures …

On the origins of the ice ages : insolation forcing, age models, and nonlinear climate change
… relationship between orbital forcing and climate variability. To place paleo and modern climate variability in context, the spectrum of temperature variability is estimated from time-scales of months to hundreds of thou- sands of years using a patchwork of proxy and instrumental records. There is …

Snow Accumulation and Melt Timing at High Elevations in Northwest Montana
… of snowmelt driven water supply to climate variability and change is difficult to assess in the mountain west, where strong climatic gradients coupled with complex topography are sampled by sparse ground measurements. We developed a snowmelt model, which ingests daily satellite imagery and …

Representation of Mean Precipitation and Decadal Variability in Atmosphere Models
… thesis, I investigated how decadal sea surface temperature variability affects precipitation over Europe and the Sahel using the atmosphere model OpenIFS. I found that European extreme precipitation is better represented at higher horizontal resolution, while the model time step has a limited …

The influence of spatiotemporal variation in ambient temperature on the ecology and physiology of birds
Ambient temperature has profound effects on the ecology, physiology and distribution of organisms. Ambient temperature regimes vary across spatial and temporal scales and understanding how organisms cope with this variation is a primary goal of ecological and evolutionary physiology. An emerging …

Ecological characteristics of stream reaches with and without low-tech process-based restoration in a wildfire-affected watershed
… characterize differences in sediment size, water temperature, benthic algae, fine and particulate organic matter, large wood, riparian vegetation, macroinvertebrate communities, and brook trout density and size structure. The relict beaver site had more shallow, lentic habitat, finer substrate, …

Reproduction, settlement, and phenology of intertidal barnacles: implications for larval dispersal
… interactions unfold in natural ecosystems where temperature variability is pervasive. In this thesis, I investigate the links between reproduction and settlement timing of intertidal barnacles, and I explore the extent to which the timing of these events is explained by environmental and …

Mechanisms of inter-annual rainfall variability over tropical highlands of Africa and its predictability potential
Modes of climate variability over tropical Africa and adjacent Atlantic and Indian Oceans are investigated using continental monthly averages of gridded rainfall and temperature and marine environmental data, which consists of monthly averages of sea surface temperature, sea level pressure and …

Variability of zooplankton and sea surface temperature in the Southern Ocean
… that the Southern Ocean circulation affects the variability of zooplankton and sea surface temperature, both of which are involved in air-sea exchanges of carbon dioxide. First, I examine the formation of spatial patterns in the distribution of Antarctic krill (Euphausia superba) resulting from …

Economic Implications of Extreme Heat Effects on Rice Yield and Milling Quality in Arkansas
<p>Future increases in global surface temperature threaten those worldwide who depend on rice production for their livelihoods and food security. Past analyses of extreme heat effects on rice production have focused on paddy yield and have not accounted for the detrimental impact of extreme heat on …

Satellite imagery evaluation of soil moisture variability in north-east part of Ganges Basin, India
Soil moisture variability across four river systems in Ganges Basin, from the Tista and Kosi Rivers in the east to the Gandak and Ghaghra-Rapti Rivers in the west, was assessed using Landsat TM Band 6 imagery dating from 1999-2003. The Band 6 thermal channel of Landsat is sensitive to soil …
