Sedimentological evidence of the level and climate changes of Lake Zeribar in the Holocene
Lakes are very interesting sedimentary environments for the study of ancient climate, changes in sedimentary environments and lake level changes. Lake Zeribar is situated in the Zagros Mountains, Kurdistan, Iran. The main purpose of this research is to examine grain size sediments, geochronology and clay mineralogy accumulated in Zeribar Lake in order to check the water level fluctuations, clim...
متن کاملResponse of a Lake Michigan coastal lake to anthropogenic catchment disturbance
A paleolimnological investigation of post-European sediments in a Lake Michigan coastal lake was used to examine the response of Lower Herring Lake to anthropogenic impacts and its role as a processor of watershed inputs. We also compare the timing of this response with that of Lake Michigan to examine the role of marginal lakes as ‘early warning’ indicators of potential changes in the larger c...
متن کاملA Preliminary Analysis of Lake Level and Water Storage Changes over Lakes Baikal and Balkhash from Satellite Altimetry and Gravimetry
Lakes Baikal and Balkhash are two of the world’s major lakes affecting fresh water supplies in their catchments. Measurements from satellite altimetry (TOPEX/Poseidon, Jason-1 and -2), satellite gravimetry (GRACE) and a hydrological model (LDAS) are used to see the relationship between lake level change (LLC) and water storage change in these two lakes. At Lake Baikal, the average rate of LLC i...
متن کاملSiliceous microfossil succession in the recent history of two basins in Lake Baikal, Siberia
As part of the international cooperative Baikal Drilling Project, siliceous microfossil assemblage succession was analyzed in two short (~ 30-cm) sediment cores from Lake Baikal. One core was recovered from the north basin (Core 324, 55°15~N, 109°30~E), a second from between the central and southern basins (Core 316, 52°28'N, 106°5rE). The northern core had higher amounts of biogenic silica (40...
متن کاملDetermination of Climate Changes on Streamflow Process in the West of Lake Urmia With Used to Trend and Stationarity Analysis
One of the most important hydrological time series task is to determine if there is any trend in the data and how to achieve stationarity when there is nonstationarity behavior in data. Detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. In this study yearly, monthly and daily stream...
