This map contains citations to U-series data from the USGS lab, published in several
articles between the late 1970’s and the early 1990’s (Szabo, Cronin et al., Mixon et al.,
Oldale et al., Muhs et al.). Data obtained more recently include those in Wehmiller et al.
2004 (Quaternary International) and unpublished results obtained on corals collected by
Wehmiller or Oches and analyzed at the University of Minnesota or Woods Hole
Oceanographic Institute.

This map has layers representing AAR data obtained by multiple laboratories using
samples from multiple sources. It also includes U-series data obtained by Muhs et al.
(1992) and Hollin and Hearty (1990). Luminescence and ESR data obtained by Burdette
et al. are also included in the map, as are sites where Sr-isotope analyses have also been
conducted on mollusks that were also analyzed for AAR. Most of the Sr-isotope data are
unpublished, although those for sites in North Carolina were published in Wehmiller et
al. (2012 – Quaternary Geochronology).
