Description
The authors conducted "a multi-core, multidisciplinary palaeolimnological study of the partially varved sediment of a deep, meromictic, arctic lake, Kongressvatnet" (Svalbard, Western Spitsbergen, 78°01'N, 13°58'E), based on measurements and analyses of "sedimentation rates, magnetic properties, varve thickness, organic matter, geochemistry, pigments from algal and photosynthetic bacteria, mineralogy and biological assemblages (diatoms, Cladocera)," which were derived from three sediment cores taken from the deepest part of Kongressvatnet. These data revealed the existence of what they describe as "the Dark Age Cold Period, the Medieval Warm Period as well as the Little Ice Age."
