(2022). Age scales for the Palmer, Jurassic, and Rendezvous Antarctic Peninsula Ice Cores (Version 1.0) [Data set]. NERC EDS UK Polar Data Centre. https://doi.org/10.5285/b3eca350-79aa-49b2-bd6b-ffee86ad6559 We present the age scales for three Antarctic Peninsula (AP) ice cores: Palmer, Rendezvous, and Jurassic. The three age scales are all from intermediate-depth cores, in the 133-141 m depth range. The Palmer age scale covers 390 years, 1621-2011 C.E., and is from one of the oldest AP cores. Rendezvous and Jurassic are from lower elevation high-snow accumulation sites and therefore cover shorter intervals, 1843-2011 C.E. and 1874-2011 C.E., respectively. The Palmer, Rendezvous, and Jurassic cores were all drilled in November-December 2012 using the British Antarctic Survey (BAS) electromechanical dry drill (without drill fluid). Water isotopes and the chemical species used to establish the age scales were measured in the ice core labs at BAS (Cambridge, UK) using Continuous Flow Analysis (CFA) or from melted discrete cut ice samples. The annual-layer markers for dating of the cores were primarily determined using nssSO4 and H2O2 summer peaks, with d18O and MSA as additional support. This research effort was carried out by the BAS Ice Core group and the established age scales will provide the foundation for multiple upcoming projects. The ice core drilling and analysis was funded by the British Antarctic Survey, Natural Environment Research Council (NERC, Cambridge, UK), part of UK research and innovation and NERC grant [NE/J020710/1]. Palmer analysis was funded by Haus der Kulturen der Welt (HKW, Berlin, Germany), in collaboration with the Anthropocene working group (AWG).

Due to its clear seasonality, and its distinct summer peaks throughout the record, nssSO4 was chosen as the primary chemical for annual layer markers and their timing (assigned as the 1st of January). The d18O, H2O2, and MSA records were evaluated simultaneously with the nssSO42 record. Data collection: The ice core records were measured in the BAS ice core laboratory. The CFA system comprises Fast Ion Chromatography (FIC), Inductively Coupled Plasma Mass Spectrometry (ICP-MS), fluorescence, and laser spectroscopy instrumentation. The processing of the data, visualization, and the manual annual layer counting was done utilizing MATLAB 2020b. Data quality: The established age scale accuracy was evaluated against and showed good agreement with known volcanic event horizons. See the listed publication for more detail. asNeeded completed
