The Main Elements of the Field Ice-wedge Sampling Strategies for Isotope and Radiocarbon Analysis

The main purpose of the paper is to create an optimal strategy for field testing wedge ice isotope and radiocarbon analyses. scientific significance this task need a detailed isotopic characterization well-dated sections with wedges. solution problem will allow us obtain complete paleotemperature scenario Holocene late Pleistocene in north Western Siberia, northern central Yakutia, Chukotka, Arctic islands. Reliable ranges composition values be obtained as result application improved method sampling. It give picture variations wedges during certain period its formation combination age setting data. provisions analyses are formulated. innovativeness proposed technique consists comparing oxygen deuterium curves from two parallel quasi-synchronous exposed by single outcrop yedoma deposits. Previously, it was believed that sampling different would same results. preliminary studies carried out author show not always case. At depths, both identical noticeably determinations were samples neighboring Predominantly horizontal deposits should still referred insufficiently developed procedure, supplemented vertical possible develop criteria excluding older 14С dates due admixture allochthonous organic material inversions only. This impossible using
