The sources and fates of nutrients in the Deep Lake watershed
… the sources and fates of nutrients within the Deep Lake watershed located in Stevens County, WA. Deep Lake is a 191-acre exorheic lake found just below the Canadian border in northeast Washington state. It is situated at the bottom of a narrow valley with steep walls and is fed throughout the …

Deep-lake carbonates and speleothems as high-resolution archives of paleohydrology in the Bonneville Basin, UT
… during the past glacial period; closed-basin lakes in this region have been studied for over a century. We present lake and speleothem records from the Bonneville Basin that are anchored by high-precision U-Th ages. Deep-lake carbonates are deposits that form beneath the surface of lakes in …

Paleolimnological Study of Chironomidae (Diptera) Assemblage Responses to Multiple Stressors in Lake Nipigon (Northwestern Ontario)
Lake Nipigon is a large, deep lake in northwestern Ontario that has experienced over a century of environmental disturbance linked to hydroelectric development, mining, and climate change. This thesis applied paleolimnological methods to reconstruct historical chironomid assemblages and their …

Predator-prey dynamics under the influence of exogenous and endogenous regulation : a data-based modeling study on spring plankton with respect to climate change
… dependence on the environmental conditions in a deep lake (Lake Constance) and a shallow marine water (mesocosms from Kiel Bight), using descriptive statistics, multiple regression models, and process-oriented dynamic simulation models. The development of the spring phytoplankton bloom, …

Caracterização geoquímica e paleoambiental do cretáceo inferior da Bacia de Camamu, Bahia
… sediments were deposited in a fault-bounded deep lake with fresh to brackish water. Organic preservation was greatly enhanced by the stable water collumn stratification and bottom anoxia. High organic carbon contents and hydrogen indices, together with the strong ¹³C isotopic depletion …

Past And Present Hydrogeology Of The Atacama Desert, Northern Chile: Human And Natural System Interactions
… and Early Pliocene, before the forearc basin was deeply incised, a lake existed in the western part of the forearc basin. New 40Ar/39Ar ages of volcanic ashes intercalated with lake and overlying fluvial deposits indicate that lacustrine deposition had begun by 10.86 ± 0.04 Ma, and the final stage …

A Multi-Archive Reconstruction of Holocene Summer and Winter Monsoon Variability in NW South Asia
… BP, gypsum from three Holocene Thar Desert playa lakes, and sub-annually resolved trace element and stable isotope data from DHAR-1 speleothem covering 4.2-2.5 ka BP. The major findings from this thesis contribute to a more comprehensive understanding of climate change in NW South Asia throughout …
