Effects of maceration on light stable isotopic (δ13C, δ18O) values of pig (Sus scrofa) rib bone carbonate
Geoprofiling isotopic analyses provide investigative leads for unidentified human remains cases by determining possible regions of origin or excluding unlikely residences during life, which in turn can reduce the number of missing persons an investigator mustconsider. However, maceration methods involving heat, bleach, baking soda, and detergents have much potential to significantly change biogenic isotopic values in the structural carbonate phas…
Little Ice Age to modern lake-level fluctuations from Ferguson's Gulf, Lake Turkana, Kenya, based on sedimentology and ostracod assemblages
Lacustrine sedimentary records and the proxies contained within them are valuable archives of past climate. However, the resolution of these records is frequently coarse or contains a high degree of uncertainty, making it difficult to resolve how climatic variability impacts the ecosystems on which humans depend. The goal of this study is to couple recent sediment cores sampled at centimeter-scale resolution with paleo- and historical information…
Biogeochemical evidence for residence, diet, and health of the Woman in the Iron Coffin (Queens, New York City)
In 2011, the mummified body of a Black adult female was discovered in a mid‐19th‐century Fisk iron coffin buried in Queens, New York City. Archival research points to the identity of the woman as Martha Peterson, a domestic worker who lived in the home of William Raymond, the business partner and neighbour of Almond Fisk, the coffin inventor and manufacturer. Here, we apply biogeochemical methods to provide information about the Woman in the Iron…
Onset of the African Humid Period by 13.9 kyr BP at Kabua Gorge, Turkana Basin, Kenya
The shift toward wetter climatic conditions during the African Humid Period (AHP) transformed previously marginal habitats into environments conducive to human exploitation. The Turkana Basin provides critical evidence for a dynamic climate throughout the AHP (~15–5 kyr BP), as Lake Turkana rose ~100 m multiple times to overflow through an outlet to the Nile drainage system. New data from West Turkana outcrops of the late-Pleistocene to early-Hol…
Freshwater distributions and water mass structure in the Amundsen Sea Polynya region, Antarctica
We present the first densely-sampled hydrographic survey of the Amundsen Sea Polynya (ASP) region, including a detailed characterization of its freshwater distributions. Multiple components contribute to the freshwater budget, including precipitation, sea ice melt, basal ice shelf melt, and iceberg melt, from local and non-local sources. We used stable oxygen isotope ratios in seawater (δ18O) to distinguish quantitatively the contributions from s…
Pedogenic carbonate stable isotopic evidence for wooded habitat preference of early Pleistocene tool makers in the Turkana Basin
Radiocarbon calibration curve spanning 0 to 50,000 years BP based on paired 230Th/234U/238U and 14C dates on pristine corals
