Simulating the Holocene lake-level record of Lake Bysjön, southern Sweden
C 14 dating ; Evapotranspiration ; Holocene ; Lake ; Lake level ; Model ; Palynology ; Precipitation ; Rill wash ; Sweden
This paper investigates whether it is possible to reproduce the observed lake-level changes at Bysjön through the Holocene by combining the effects of precipitation changes and known changes in radiation and temperature regimes, and whether
this results in more plausible estimates of changes in Holocene precipitation. These investigations are carried out using a physically based lake-catchment model, driven by known changes in radiation and temperature regimes and by systematic changes
Sedimentation in Chilko Lake : a record of the geomorphic environment of the eastern Coast Mountains of British Columbia, Canada
British Columbia ; Canada ; Dating ; Deglaciation ; Geophysics ; Lacustrine sedimentation ; Lake ; Palaeo-environment ; Sediment budget ; Varves
Fieldwork at Chilco Lake was carried out in July 1994. The objectives of this study are : 1) to ascertain the quantity, rate, and processes of sediment delivery to a large, glacier-fed lake to the east of the axis of the Coast Mountains; 2
) to consider how the hydroclimate and sediment routing in this environment can explain the pattern and quantity of deposition compared to other large lakes west of the axis; and 3) to determine the role of large lakes in the regional pattern of sediment
The hydrological development of Lake Müritz in the Late Quaternary. Records and their interpretation
Climatic variation ; Diatom ; Geochemistry ; Germany ; Holocene ; Human impact ; Lake ; Lake level ; Mecklenburg-West Pomerania ; Palaeo-environment ; Palaeohydrology ; Quaternary
Geological, geomorphological, archaeological and historical records allow a reconstruction of the hydrological development of Lake Müritz (Mecklenburg-Vorpommern, Northeast-Germany) in the Late Quaternary. After a very high lake-level
in the Weichselian the lake-level in the early Holocene was some metres lower than at present. In the Mid- and Late Holocene the lake-level rose up which fluctuations. Lake-level fluctuations before Medival Times seem to have been caused by climatic changes, lake
Lake levels since about 40,000 years ago at Lake Chalco, near Mexico city
C 14 dating ; Diatom ; Holocene ; Lacustrine sediment ; Lake ; Lake level ; Magnetic susceptibility ; Mexico ; Mexico City ; Palaeo-environment ; Pleistocene ; Quaternary ; Volcanism
The AA. present a paleolimnological record from the central part of Lake Chalco (diatoms, magnetic susceptibility, organic content, C 14 ages of sediments). This record, spanning at least 40,000 yr, offers a more detailed interpretation of the last
-glacial and post-glacial environmental history of this lake. The AA. also use recent volcanological findings to explore how volcanic activity may have affected the lake's history.
Glacioisostasy and lake-level change at Moosehead Lake, Maine
C 14 dating ; Deglaciation ; Geophysics ; Glacial isostasy ; Holocene ; Lake ; Lake level ; Model ; Palaeo-environment ; Stratigraphy ; Thermoluminescence ; United States of America
Reconstructions of glacioisotatic rebound based on relative sea level in Maine and adjacent Canada do not agree well with existing geophysical models. In order to understand these discrepancies better, the AA. investigated the lake-level history
of 40-km-long Moosehead Lake in northwestern Maine. The rebound history inferred from lake-level data is consistent with previous interpretations of nearby relative sea-level data, which indicate a significantly steeper and faster-moving ice-proximal
Late Quaternary variations in the level of paleo-Lake Malheur, eastern Oregon
Archeological site ; C 14 dating ; Dune ; Holocene ; Lake ; Lake level ; Oregon ; Palaeolake ; Quaternary ; United States of America
The present Malheur Lake system, which includes Malheur, Harney, and Mud Lakes, contains one of the largest freshwater marsh habitats in the United States. Although the lake typically is no more than 3 m deep, it can experience very dynamic water
-level fluctuations and spatial variation. Beginning ca. 5000 yr B.P., based on shells in the Malheur Lake dune islands, the Malheur Lake system's environmental history is marked by fluctuating water levels, a pattern apparently characterizing

Brackish environment ; Coastal dynamics ; Coastal environment ; Coastal geomorphology ; Freshwater environment ; Lake ; New Zealand ; Pool ; Sand bar ; Sea level ; South Island
Documentary and anecdotal evidence is presented to supplement geomorphological evidence for the conversion of Lake Forsyth (Wairewa) from marine inlet to brackish to freshwater lake within near historic time. Growth of the barrier across the lake
Correlation of Late-Pleistocene lake-level oscillations in Mono Lake, California, with North Atlantic climate events
C 14 dating ; California ; Climatic variation ; Correlation ; Lacustrine sediment ; Lake level ; Marine sediment ; North Atlantic Ocean ; Oxygen 18 ; Palaeogeography ; Pleistocene ; Quaternary ; United States of America
In this study, the AA. have employed paleomagnetic secular variation (PSV) data obtained on North Atlantic and Mono Lake sediments as well as O 18 and total inorganic carbon (TIC) measurements of Mono Lake sediments to show that lowstands of Mono
Lake occurred during Heinrich events H1, H2, and H4. These results enforce the concept that relatively dry-wet oscillations in the climate of the Great Basin of the western United States occurred at approximately the same times as cold-warm oscillations
Stratified marine lakes of Palau (Western Caroline Islands)
Belau ; Carbonate rock ; Ecosystem ; Hydrobiology ; Hydrochemistry ; Karst ; Lake ; Marine hydrology ; Pacific Region ; Salinity ; Sea level ; Tide ; Water stratification ; Water temperature
The AA describe some of the physical and chemical attributes of eleven meromictic marine lakes in Palau, of which 8 are on the island of Mecherbar, 2 are on the island of Koror, and 1 is on the island of Urukthapel. They also describe a holomictic
marine lake from Mecherbar and a marine lake with a variable pattern of tidal mixing from Gologuguel Island, which are important for the discussion. Their emphasis is on water-column stratification, patterns of tidal mixing, and temporal stability
of selected lakes over a period of 18 years. The AA. make brief remarks throughout about the biology of some of the lakes.

This article gives a summary of the studies of the history of Lake Ladoga after the last glaciation, seen against the general development of Quaternary studies. The early studies were influenced by the Deluge theory, which later was replaced
Paleomagnetic investigation of the Bonneville Alloformation, Lake Bonneville, Utah
California ; Geochronology ; Lacustrine sediment ; Lake level ; Nevada ; Palaeo-ecology ; Palaeomagnetism ; Pleistocene ; Quaternary ; United States of America ; Utah
Paleomagnetic secular variation in a portion of the Bonneville Alloformation is compared with secular variation in lacustrine sediments in the Mono Basin, California, and with secular variation in Lake Lahontan sediments in the northwestern Great
Basin. The deposition occurred during a transgressive stage of Lake Bonneville and coincided with a wet period in the Lahontan Basin.
Northwest outlet channels of Lake Agassiz, isostatic tilting and a migrating continental drainage divide, Saskatchewan, Canada
C 14 dating ; Canada ; Drainage network ; Glacial features ; Glacial lake ; Glaciolacustrine ; Holocene ; Isostasy ; Lacustrine sediment ; Palaeo-environment ; Saskatchewan ; Stratigraphy
Lake cores obtained from the northwest outlet glacial Lake Agassiz in northwest Saskatchewan, provide a minimum date for the cessation of the flood from the northwest outlet, and a chronology for abandonment of mid-Holocene channels that presently
straddle the Mackenzie and Churchill drainage divide. Holocene differential isostatic uplift caused the flow reversal in the upper Churchill basin. Anastomosed channels at the mouth of rivers flowing north into lakes indicate that uplift is still active
Early Pleistocene glacial Lake Lesley, West Branch Susquehanna River valley, central Pennsylvania
Dating ; Fluvioglacial features ; Geochronology ; Glacial features ; Palaeo-environment ; Palaeomagnetism ; Pennsylvania ; Pleistocene ; Proglacial lake ; Stratigraphy ; United States of America
The AA. use new exposures in the West Branch Susquehanna River (WBSR) valley and magnetostratigraphy to reconstruct depositional environments in Glacial Lake Lesley, constrain the age of Glacial Lake Lesley, and constrain the maximum extent
of Glacial Lake Lesley. To achieve these objectives, detailed stratigraphic sections were described at McElhattan and Linden. The AA. use paleomagnetism as an age correlation tool in the WBSR valley to correlate contemporeanous glaciofluvial and proglacial
Geochemical characterization of soil organic matter and variability of a postglacial detrital organic supply (Chaillexon Lake, France)
This paper deals with a geochemical investigation (Rock-Eval pyrolysis) of soil organic matter sampled in a lake watershed, and the study of the sedimentary organic matter trapped in the lake deposits. The research was conducted on Chaillexon Lake
Evidence at Lomax, Illinois, for Mid-Wisconsin (≃40,000 yr B.P.). Position of the Des Moines Lobe and for diversion of the Mississippi River by the Lake Michigan Lobe (20,350 yr B.P.)
Glacial lake ; Illinois ; Mississippi ; Multivariate analysis ; Palaeo-environment ; Palaeoclimate ; Palaeohydrology ; Pleistocene ; Quaternary ; Stream ; United States of America
An abrupt change in environment from a wetland to a deeper slackwater lake at 20,345 yr B.P. occurred in a second-order valley tributary to the Mississippi River near Lomax, Illinois. The age of this shift is associated with the overflow of glacial
Lake Milan and diversion of the Mississippi River from the Princeton Valley (Rock Island to Peoria) to its present course (Rock Island to St. Louis). In this paper, the paleohydrology and paleoclimatology at Lomax is interpreted based on evidence from
Late Holocene climatic changes in western equatorial Africa inferred from pollen from Lake Sinnda, southern Congo
Pollen analysis of 2 cores from the Lake Sinnda, located in one of the driest areas of the southern Congo, reveals a history of vegetation and climate in this region during the past 5000 yr. A major change centered around 3000-2500 yr B.P
. is indicated by an abrupt decrease in forest pollen and by a corresponding increase in grassland pollen. Concurrent drying up of the lake shows that climate, in particular aridity, was the major cause of this change. The aridity predates agriculture marked

The AA. discuss the timing of the last, and most dramatic, pluvial event recorded in Lake Lahontan and Searles Lake, and of distinct dry periods recorded as evaporite layers in the Searles basin. The last major pluvial events in these closed basins
Late Holocene lake sedimentology and climate change in Southern Alberta, Canada
Alberta ; Canada ; Climatic variation ; Grain size distribution ; Holocene ; Lacustrine sediment ; Lake ; Palaeo-environment ; Palaeoclimatology ; Tephrochronology
Climatic changes in southern Alberta, Canada, for the past 4000 yr are reflected in a high-resolution record of lake sediment grain size. The proposed mechanism for this response is that outflow discharge removes fine-grained sediments
, but increasingly fine sediments are retained and deposited as streamflow declines. The grain-size record from Pine Lake reflects historic climate fluctuations, as well as prehistoric fluctuations including the Little Ice Age and the Medieval Warm Period. Grain size
