Heterogeneous ices in ice wedges structure on the Pur-Taz interfluve peatlands of the north of West Siberia

Лëд и снег, 2020
Structure of arctic peatlands with massive ice and structure-forming ice were studied in drained lake («khasyrey») of the Pur-Taz interfluves (the north of West Siberia). The period of accumulation of two-meter thickness of the peat was established to be

Bayesian age models and stacks: combining age inferences from radiocarbon and benthic δ¹⁸O stratigraphic alignment [PDF]

Climate of the Past, 2023
Previously developed software packages that generate probabilistic age models for ocean sediment cores are designed to either interpolate between different age proxies at discrete depths (e.g., radiocarbon, tephra layers, or tie points) or perform a ...

Assessing the ability of the 14C projection-age method to constrain the circulation of the past in a 3-D ocean model [PDF]

, 2008
Radiocarbon differences between benthic and planktonic foraminifera (B-P ages) and radiocarbon projection ages are both used to determine changes of the past ocean circulation rate.
