RADIOLARIAN BIOSTRATIGRAPHIC AND PALEOCEANOGRAPHIC STUDIES OF MONTEREY-LIKE ROCKS OF THE HUMBOLDT BASIN, NORTHERN CALIFORNIA
… in the California Current System are the dominant controls on faunal distribution and organic carbon preservation. An example of doming of deep water masses (Weinheimer et al., 1986) indicating analogous El Nino-like circulation is detected and differentiated from other similar appearing …

Petrology and diagenesis of the lower Mississippian Price Formation, southwestern Virginia
… Price Formation was to determine the dominant controls on diagenesis and porosity as the Price sandstones are potential reservoirs for coalbed methane. Facies analyses of the cores, in combination with outcrop data from previous studies, lead to the conclusions that these rocks …

Investigating Subsurface Flow Delivery to a Small High Arctic River
… the hillslope-floodplain-channel continuum are dominant controls on the delivery of baseflow, stormflow and solutes to channels in temperate systems. Arctic systems are increasingly being shown to possess similar delivery mechanisms, however the topic is understudied, acutely so in the High …

Trace elements in marine biogenic carbonates: analysis and application to past ocean chemistry
… foraminiferal habitat and dissolution as controls<br/>on Mg/Ca. Determinations of Cd/Ca in seven species of planktonic foraminifera<br/>confirm that the dominant controls on Cd/Ca are foraminiferal habitat and hydrography,<br/>with only a minor influence of post depositional dissolution. …

The sedimentology of the cambrian clastic sediments of Northwest Scotland
… buried under carbonate platform sediments. The dominant controls on the facies developed in this sequence were thermal subsidence, eustatic sea level rise and tidal resonant effects. Two rapid shallowing events, in the middle of the Pipe Rock and at the top of the Fucoid Beds, may have been …

Predicting malaria dynamics under climate change
… Climate change drives shifts in microtopographic controls on the persistence of mosquito habitat and the life cycles of Anopheles vector and Plasmodium parasite, which affect the transmission of malaria. The ability to accurately predict malaria dynamics in the future requires the consideration of …

Vegetation Variability and Its Hydro-Climatologic Dependence
… of vegetation, its dependence on hydrologic controls such as topography, soil properties, vegetation type, and climate variations (e.g., the El Nino Southern Oscillation [ENSO]), and to synthesize this understanding for future predictive modelling applications. The initial phase of this study …

Upwelling dynamics off Monterey Bay : heat flux and temperature variability, and their sensitivities
… studies to determine which variables are dominant controls for upwelling events in the Monterey Bay region. Our motivations include determining the dominant atmospheric fluxes and the causes of high-frequency fluctuations found in ocean thermal balances. We focus on the first upwelling …

Using the growth patterns and geochemistry of coralline red algae to develop proxies for paleoclimate reconstruction in tropical and subarctic environments
… bands (n = 0-20) in <6 months and that the more dominant controls on growth are light and axial branch orientation to the light source. These results highlight the importance of calibration studies to develop paleo-archives. The trace elemental content of the GOP rhodoliths revealed that the …

Data-driven analyses of watersheds as coupled human-nature systems
… integrity. We also aim to understand how the dominant controls of these emergent properties change through time. This study targets these needs by quantitatively linking natural and anthropogenic drainage area characteristics to flow frequency and measures of ecological health using data …
