Sediments of Lake Vens (SW European Alps, France) record large-magnitude earthquake events
Springer Science and Business Media LLC - Tập 51 - Trang 343-355 - 2013
We studied sediment cores from Lake Vens (2,327 m asl), in the Tinée Valley of the SW Alps, to test the paleoseismic archive potential of the lake sediments in this particularly earthquake-sensitive area. The historical earthquake catalogue shows that moderate to strong earthquakes, with intensities of IX–X, have impacted the Southern Alps during the last millennium. Sedimentological (X-ray images...... hiện toàn bộ
The San Nicolás succession of the Cauca paleolake: a late Holocene laminated ria lake record from the Neotropics
Springer Science and Business Media LLC - Tập 49 - Trang 287-300 - 2013
The stratigraphic, geochemical, and organic matter study of the late Holocene San Nicolás succession of the Cauca paleolake (Santa Fé–Sopetrán pull-apart basin) in the middle Cauca Valley, northern Colombia, suggests that it was deposited in a ria lake environment, at sedimentary accumulation rates in excess of 600 cm ky−1 between ~3500 and ~500 yr BP. Laminated deposition occurred, first under ig...... hiện toàn bộ
Understanding controls on stanols in lake sediments as proxies for palaeopopulations in Mesoamerica
Springer Science and Business Media LLC - Tập 67 - Trang 375-390 - 2022
Faecal stanols in lake sediments have been used as a proxy for human populations in the past in a variety of contexts, with the assumption that variability in faecal stanol concentration or ratios is a reliable proxy for relative catchment-scale human populations. Despite that, the specific controls on faecal stanol concentrations and ratios in lake sediments remain poorly understood. In this stud...... hiện toàn bộ
Diatoms as indicators of climatic and limnological change in Swedish Lapland: a 100-lake calibration set and its validation for paleoecological reconstructions
Springer Science and Business Media LLC - Tập 27 - Trang 97-115 - 2002
This study investigated the distribution of subfossil diatom assemblages in surficial sediments of 100 lakes along steep ecological and climatic gradients in northernmost Sweden (Abisko region, 67.07° N to 68.48° N latitude, 17.67° E to 23.52° E longitude) to develop and cross-validate transfer functions for paleoenvironmental reconstruction. Of 19 environmental variables determined for each site,...... hiện toàn bộ
Enhanced middle Holocene organic carbon burial in tropical floodplain lakes of the Pantanal (South America)
Springer Science and Business Media LLC - Tập 65 - Trang 181-199 - 2020
Wetland carbon storage is an important and environmentally sensitive ecosystem service. Carbon burial in the floodplain lakes of the Pantanal (tropical South America) appears to have varied during the late Quaternary, but several paleolimnological studies have recorded unusually high sediment organic carbon content from ~ 7.3 to 6.0 cal kyr BP in lakes connected to the Upper Paraguay River. We con...... hiện toàn bộ
A diatom record of environmental change in Fryxell Basin, Taylor Valley, Antarctica, late Pleistocene to present
Springer Science and Business Media LLC - Tập 46 Số 2 - Trang 257-272 - 2011
Response of the St. Joseph River to lake level changes during the last 12,000 years in the Lake Michigan basin
Springer Science and Business Media LLC - Tập 37 - Trang 383-394 - 2007
The water level of the Lake Michigan basin is currently 177 m above sea level. Around 9,800 14C years B.P., the lake level in the Lake Michigan basin had dropped to its lowest level in prehistory, about 70 m above sea level. This low level (Lake Chippewa) had profound effects on the rivers flowing directly into the basin. Recent studies of the St. Joseph River indicate that the extreme low lake le...... hiện toàn bộ
An 1800-year record of lake level and climate change from alkaline lakes in southern Inner Mongolia, China
Springer Science and Business Media LLC - Tập 67 - Trang 59-73 - 2021
Paleoclimatic records from the East Asian summer monsoon (EASM) margin are regarded as a direct reflection of the intensity and northern extent of the EASM. Here, we focus on reconstructing climatic evolution over the past 1800 years from two alkaline lakes, Chagan Nuur and Sangin Dalai Nuur, in southern Inner Mongolia. With age control provided by 13 Accelerator Mass Spectrometry radiocarbon ages...... hiện toàn bộ
Clearing the muddy waters: using lake sediment records to inform agricultural management
Springer Science and Business Media LLC - Tập 53 - Trang 1-15 - 2014
Milltown Lake is located in the Irish drumlin belt where small lakes are interspersed amongst rolling hills. Because of poor drainage characteristics of soils in this region, grassland agriculture dominates, with beef rearing and dairying as the main agricultural enterprises. We used paleolimnological techniques in conjunction with export coefficients to investigate the relationship between histo...... hiện toàn bộ
