  • Advances in Quaternary tephrostratigraphy and tephrochronology in New Zealand

    Lowe, David J.; Newnham, Rewi M. (1999)
    This paper summarises recent studies on Quaternary tephra deposits in New Zealand, and refers to a range of tephrochronological applications including sequence stratigraphy, palaeoclimatic reconstruction, and archaeology. ...
  • The advent of the Anthropocene in Australasia.

    Bostock, Helen C.; Lowe, David J.; Gillespie, Richard; Priestley, Rebecca; Newnham, Rewi M.; Mooney, Scott D. (Australasian Quaternary Association (AQUA), 2015-07-21)
    As early as the late 19th Century, several scientists had suggested that humans were starting to influence the physical environment of planet Earth (e.g. Marsh, 1864; Stoppani, 1873; Arrhenius, 1896; Chamberlain, 1897). ...
  • Ages of 24 widespread tephras erupted since 30,000 years ago in New Zealand, with re-evaluation of the timing and palaeoclimatic implications of the Lateglacial cool episode recorded at Kaipo bog

    Lowe, David J.; Blaauw, Maarten; Hogg, Alan G.; Newnham, Rewi M. (Elsevier Ltd., 2013)
    Tephras are important for the NZ-INTIMATE project because they link all three records comprising the composite inter-regional stratotype developed for the New Zealand climate event stratigraphy (NZ-CES). Here we firstly ...
  • Can oxygen stable isotopes be used to track precipitation moisture

    Amesbury, Matthew J.; Charman, Dan J.; Newnham, Rewi M.; Loader, Nwil J.; Goodrich, Jordan Paul; Royles, Jessica; Campbell, David I.; Keller, Elizabeth D.; Baisden, W. Troy; Roland, Thomas P.; Gallego-Sala, Angela V. (Elsevier, 2015-08-14)
    Variations in the isotopic composition of precipitation are determined by fractionation processes which occur during temperature- and humidity-dependent phase changes associated with evaporation and condensation. Oxygen ...
  • Carbon stable isotopes as a palaeoclimate proxy in vascular plant dominated peatlands

    Amesbury, M.J.; Charman, D.J.; Newnham, Rewi M.; Loader, N.J.; Goodrich, Jordan Paul; Royles, Jessica; Campbell, David I.; Roland, Thomas P.; Gallego-Sala, Angela (PERGAMON-ELSEVIER SCIENCE LTD, 2015-09)
    Carbon stable isotope (δ¹³C) records from vascular plant dominated peatlands have been used as a palaeoclimate proxy, but a better empirical understanding of fractionation processes in these ecosystems is required. Here, ...
