Characterization and Calibration of Lamination Stratigraphy of Cores Recovered from Lake Linné, Svalbard Norway, 2005

The lamination stratigraphy of cores recovered from Lake Linné have been characterized and correlated to modern process data, instrumental weather records, and recent glacier mass balance data. The purpose of this work is to calibrate the top 25 cm of cores to records of environmental change during the past 50 years to serve as a calibration in order to understand environmental change during the late Holocene. Sediment cores recovered from glacier-fed Lake Linné contain varved millimeter-scale silt/clay laminations offering annual records of past conditions. Four short cores (<0.5 m long) and four long cores (approximately 2.3 m long) were recovered from three different locations in Lake Linné in August 2004 and May 2005. Cores contain millimeter to centimeter-scale laminations, which are best studied in thin section. Color and grain size changes define silt and clay couplets between 0.5 and 11 mm in thickness. Distinctive laminations can be correlated between cores from locations 0.5 km apart indicating lamintation stratigraphy represents basin-wide depositional events.
