| Summary: | Abstract: Radiocarbon dates from pygoscelid penguin tissues from ornithogenic soils and beach deposits at Stranger Point, King George (25 de Mayo) Island, Antarctic Peninsula. Uncorrected dates are in radiocarbon years before present (BP); calibrated dates were corrected for the marine carbon reservoir effect (delta R = 700 +/- 50 years) and calibrated with Calib 7.0.4 to provide 2σ ranges in calendar years BP. All dates except were completed at the Woods Hole National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) facility and are designated with OS numbers. Localities include ancient penguin breedings sites (mounds, M), active colonies (I9, B3), and a mid-Holocene marine beach deposit (Pingfo 1).
