“…Recently such qualitative information has been supplemented by estimates of absolute temperature changes based on fossil Coleoptera (Lemdahl, 1988(Lemdahl, , 1991Hammarlund and Lemdahl, 1994). There is also the potential for deriving quantitative palaeoclimatic data from oxygen isotope records obtained on autochthonous lacustrine carbonates, as demonstrated using subfossil ostracods in southern Germany by von Grafenstein et al (1994), although this approach has not yet been applied to characterise the climate of GS-1 in Scandinavia.…”

The isotope composition of authigenic and biogenic carbonates and diatom silica are commonly used as palaeoclimate proxies from lake sediments. This article reviews the controls on the isotope composition of lacustrine skeletal and non skeletal deposits and illustrates how stable isotope studies contribute to an understanding of changes in temperature, precipitation patterns, evaporation and the carbon cycle. It highlights the differences in the palaeoclimate potential of a wide range of lakes ranging from open to closed lake basins. A large number of the case histories, but not all, are drawn from studies of temperate lakes from Europe.Large closed lake systems, in the tropics and elsewhere, lose water predominantly through evaporation, and contain sediments with variable and generally high δ O values that vary by no more than a few ‰. These variations are generally ascribed to variations in temperature or the isotope composition of precipitation (δp), from which either an annual or seasonally specific signal can be gained. These types of lakes are common in Northern Europe and at high altitudes. The interpretation of isotope data from a lacustrine succession requires a knowledge of the local processes that might control and modify the signal. Their effects need to be quantified, and a robust calibration using the modern lake system is necessary to establish the relationship between the measured signal, the isotopic composition of the host waters, and climate.

“…In this paper, we show that dissolved oxygen (DO) is a key environmental determining factor for the presence or absence of ostracodes. Two independent methods are typically used to reconstruct past hydrological conditions: autecology (Delorme 1969;Curry and Delorme 2003), and valve biogeochemistry (Von Grafenstein et al 1994;Ito and Forester 2009). The most robust reconstructions come from sites where the modern lake still exists.…”

Low dissolved oxygen during the summer and early fall controls profundal continental ostracode distribution in Crystal Lake (McHenry County), Illinois, favoring Cypria ophthalmica and Physocypria globula at water depths from 6 to 13 m. These species also thrived in the lake's profundal zone from 14,165 to 9600 calendar year before present (cal yr B.P.) during the late Bølling, Allerød, and Younger Dryas chronozones, and early Holocene. Characterized by sand, cemented tubules, large aquatic gastropod shells, and littoral ostracode valves, thin (1-6 cm) tempestite deposits punctuate thicker deposits of organic gyttja from 16,080 to 11,900 cal yr B.P. The succeeding 2300 yr (11,900-9600 cal yr B.P.) lack tempestites, and reconstructed water depths were at their maximum. Deposition of marl under relatively well-oxygenated conditions occurred during the remainder of the Holocene until the arrival of Europeans, when the lake returned to a pattern of seasonally low dissolved oxygen. Such conditions are also indicated in the lake sediment by the speciation of phosphorus, high concentrations of organic carbon, and abundant iron and manganese occluded to mineral grains. Initial low dissolved oxygen was probably caused by the delivery of dissolved P and Fe in shallow groundwater, the chemistry of which was influenced by Spodosol pedogenesis under a spruce forest. The triggering may have been regionally warm and wet conditions associated with retreat of the Lake Michigan lobe (south-central Laurentide Ice Sheet).
