Estimation of sedimentary proxy records together with associated uncertainty

Abstract: Abstract. Sedimentary proxy records constitute a significant portion of the recorded evidence that allows us to investigate paleoclimatic conditions and variability. However, uncertainties in the dating of proxy archives limit our ability to fix the timing of past events and interpret proxy record intercomparisons. While there are various age-modeling approaches to improve the estimation of the age-depth relations of archives, relatively little focus has been placed on the propagation of the age (and radiocarb… Show more

“…Such correlations between locations are probably relevant for some noise terms while they are probably less important for others. We focused on the time series approach and did not choose a probabilistic approach like, for example, Breitenbach et al (2012) or Goswami et al (2014). Neither does our approach as of now explicitly link to probabilistic age modelling approaches as described by Haslett and Parnell (2008), Blaauw and Christen (2011), or Trachsel and Telford (2017).…”

“…There are a number of approaches to transfer the dating uncertainty towards the proxy record error (e.g. Breitenbach et al, 2012;Goswami et al, 2014;Boers et al, 2017). Ensemble and Bayesian age-depth modelling approaches also allow us to infer an additional error term (e.g.…”

“…The 14 C series of the Suigetsu sediments, shown here in Fig. 5a, has been used as a comparison curve to fit radiometrically dated archives -such as speleothem data (Hoffmann et al, 2010;Southon et al, 2012) -onto the Suigetsu varve chronology. As done in the previous section for NGRIP, we represent in Fig.…”
