Abstract

Lake sediments accumulate material derived from the atmosphere, the lake catchment, and the lake itself, and these materials can be used to infer the history of aquatic and terrestrial ecosystems, the climate system, and global biogeochemical cycling. Several case-studies will be presented to discuss the reconstruction of environmental variability from the paleolimnological record including studies of (1) Climate history: Closed-basin lakes are sensitive recorders of changes in the hydrologic budget and are used in and semi-arid regions to assess patterns of long- and short-term variability in moisture availability; (2) Biogeochemical cycling/pollution history: Basin-wide measurement of mercury accumulation in lake sediments is used to estimate modem and pre-industrial rates of mercury deposition and the contribution of global vs regional sources; and (3) Acidification history: Lake-pH is reconstructed from aquatic microfossils and correlated with changes in pollutant deposition and terrestrial vegetation to evaluate the extent, timing, and causes of acidification.

Assessing trends in fishery resources and lake-water aluminum from paleolimnological analyses of siliceous algae

Technical Report Kingston, J; Birks, H; Uutala, A; ...

Lake water aluminum concentrations have a significant influence on the composition of microfossil assemblages of diatoms and chrysophytes deposited in lake sediments. With the paleolimnological approach of multilake datasets in the Adirondack region of New York, USA, the authors use canonical correspondence analysis to describe past trends in lake water Al. Four lakes, previously investigated regarding acidification and fishery trends, are used to demonstrate that paleolimnological assessment can also provide direction, timing, and magnitude of trends for both toxic metals and fish resources. Additionally, the authors use weighted average regression and calibration to obtain quantitative reconstructions of past lake watermore »« less
Late cenozoic lacustrine and climatic environments at Tule Lake, northern Great Basin, USA

Journal Article Bradbury, J - Climate Dynamics

Cores of lake sediment to a depth of 334 m in the town of Tulelake, northern California, document the late Cenozic paleolimnologic and paleoclimatic history of the northwestern Great Basin. Lacustrine diatoms are abundant throughout the record documenting a nearly continuous paleolimnologic history of the Tule Lake basin. Except for a drier (and cooler?) interval recorded by Fragilaria species about 2.4 Ma, the Pliocene is characterized by a dominance of planktonic Aulacoseira solida implying a warm monomictic lake under a climatic regime of low seasonality. Much of the Pleistocene is dominated by Stephanodiscus and Fragilaria species suggesting a cooler, drier,more »« less

Do the paleolimnological reconstructions reflect the influence of acid deposition?

Conference Smirnov, D

The using possibility of paleolimnological analyses was considered with the documentation aim of acid-forming substances distant transfer on territory of Northern Fennoscandia. The Holocene and ancient interglacial lakes pH-and alkalinity trends, reconstructed by means of bottom sediments diatomic analyses, were studied. It has been made evident that the tendency to sharp changes of these data is revealed on final stages of interglacial periods. At that time the high amplitude of climatic changes with low periodicity is resulting in catastrophic changes of landscapes in the frames of water-catchments bodies. During the last millennium the climatic situation in the Northern Fennoscandia wasmore »« less
A Geochemical and Sedimentary Record of High Southern Latitude Holocene Climate Evolution from Lago Fagnano, Tierra del Fuego

Journal Article Moy, C; Dunbar, R; Guilderson, T; ... - Earth and Planetary Sciences Letters, vol. 302, no. 1-2, February 1, 2011, pp. 1-13

Situated at the southern margin of the hemispheric westerly wind belt and immediately north of the Antarctic Polar Frontal zone, Tierra del Fuego is well-positioned to monitor coupled changes in the ocean-atmosphere system of the high southern latitudes. Here we describe a Holocene paleoclimate record from sediment cores obtained from Lago Fagnano, a large lake in southern Tierra del Fuego at 55{sup o}S, to investigate past changes in climate related to these two important features of the global climate system. We use an AMS radiocarbon chronology for the last 8,000 years based on pollen concentrates, thereby avoiding contamination from bedrock-derivedmore »« less

Eustatic control of tertiary hydrocarbon deposits, Central California borderline basins

Conference Cousminer, H - AAPG Bulletin (American Association of Petroleum Geologists); (United States)

In the central California borderland basins, the Vail-Haq Cenozoic Global Eustatic Cycle appears to have influenced depositional patterns that have fundamental significance in the present distribution of hydrocarbon source and reservoir beds. Coupled with tectonic events, traps were created that now control the distribution of hydrocarbon accumulations. Seismic data combined with subsurface lithostratigraphic, biostratigraphic, and log data from wells drilled on the central California outer continental shelf (OCS) were used to date and correlate Tertiary stratigraphic sequences in the Santa Maria, Bodega-La Honda, and Point Arena basins. Benthic foraminiferal assemblages also served to reconstruct each basin's paleobathymetric history. The westmore »« less
