The Lower Mystic Lake (Medford/Arlington, MA) is a 24 m deep, ectogenically meromictic, low elevation (1 m a.s.l.), coastal lake directly connected to Boston Harbor by the Mystic River. About 1,000 ye...
Paleoceanography and paleoenvironmental changes of the Cenomanian-Turonian boundary interval (94-93 Ma): The record of Oceanic Anoxic Event 2 in the central and eastern parts of the Western Interior Sea
Cretaceous Oceanic Anoxic Event 2 Cenomanian-Turonian boundary Foraminifera Paleoceanography Western Interior Sea
2014/10/22
The Cenomanian/Turonian (C/T) boundary marine strata of the Late Cretaceous Western Interior Sea (WIS) exhibit a positive carbon isotopic excursion in the bulk-carbonate and organic carbon. This marks...
A High-Resolution Temperature Record from Lakes of the Lofoten Islands, Northwestern Norway based on a New UK37 Temperature Calibration from in situ Measurements
A High-Resolution Temperature Record Lakes of the Lofoten Islands Northwestern Norway a New UK37 Temperature Calibration
2014/10/22
The temperature-sensitive lipids, long chain alkenones (LCAs), are considered to be a powerful paleothermometer in deciphering the variability of sea surface temperature (SST) through time. Recent stu...
Holocene Climate and Environmental Changes: Disentangling Natural and Anthropogenic Signals in the Sedimentary Record of Lake Lilandsvatnet (NW Norway),
Holocene Climate and Environmental Changes Disentangling Natural Anthropogenic Signals Sedimentary Record of Lake Lilandsvatnet

This thesis presents a multi-proxy paleoenvironmental reconstruction from the sedimentary archives of Lilandsvatnet, a small arctic lake on Vestvågøy, in the Lofoten Islands, Norway. Lofoten...
Holocene Paleo-environmental Variability Reconstructed from a Lake Sediment Record from Southeast Greenland
Holocene Paleoenvironmental Variability Reconstructed a Lake Sediment Record Southeast Greenland
2014/10/21
Arctic climate variability over the Holocene has been both extensive and, at times, abrupt. Current understanding of these changes is still quite limited with few highresolution paleoclimate records a...
Update of the Chronology of Natural Signals in the Near-Surface Mean Global Temperature Record and the Southern Oscillation Index
Climate Variability Southern Oscillation Index ENSO
2013/3/11
Time series for the Southern Oscillation Index and mean global near surface temperature anomalies are compared for the 1950 to 2012 period using recently released HadCRU4 data. The method avoids a foc...
A contribution to improved flood magnitude estimation in base of palaeoflood record and climatic implications–Guadiana River(Iberian Peninsula)
flood magnitude estimation palaeoflood record climatic implications
2009/12/16
The Guadiana River has a significant record of historical floods, but the systematic data record is only 59 years. From layers left by ancient floods we know about we can add new data to the record, a...
