Biases in radiocarbon dating of organic fractions in sediments from meromictic and seasonally hypoxic lakes [PDF]
Bulletin of the Geological Society of Finland, 2019 We present here radiocarbon dating results from two boreal lakes in Finland, which are permanently (meromictic) or seasonally stratified and contain continuous sequences of annually laminated sediments that started to form in the early Holocene.

Exploring site formation and building local contexts through wiggle-match radiocarbon dating: re-dating of the Firth of Clyde Crannogs, Scotland [PDF]
, 2017 There are at least four wooden intertidal platforms, also known as marine crannogs, in the Firth of Clyde, on the west coast of Scotland. The interpretation of these sites partly depends on their dating and, if coeval, they could point to the presence of

AMS radiocarbon dating from the Neolithic of eastern Ukraine casts doubts on existing chronologies [PDF]
, 2015 The Seversky Donets River (Northern Donets) basin in eastern Ukraine and the Lower Don River valley in Russia were inhabited by populations that have been considered to be one of the earliest pottery-using cultures in Europe.

Copenhagen Radiocarbon Dates VI [PDF]
Radiocarbon, 1960 The following list comprises a selected number of measurements made up to November 1963. Age calculations are based on a contemporary value equal to 95% of the activity of the NBS oxalic-acid standard, and on a half life for C14of 5570 ± 30 yr.Results are expressed in years before 1950 and in the b.c.-a.d. scales.

Optical dating and sedimentary record from the terrace depositional profile of the Warta River (Central Poland) [PDF]
, 2014 Results of OSL dating and sedimentary studies from the profile of the low alluvial terrace of the middle Warta River are presented. The samples were dated using the single-aliquot regenera-tive method.
