Geochemical proxies for environmental change in Lake Pupuke, Auckland, New Zealand

Abstract

Accumulated sediments within Lake Pupuke represent a high-resolution, continuous record of change from crater formation (ca. 200 kyr) to present. This study represents a component of the ongoing NZ-Maar project which aims to establish a reliable high-resolution Late Quaternary climatic history for the Auckland region based on multi-proxy investigations of the Auckland maar lakes. Here a multi-proxy record from Lake Pupuke sediment spanning the last ca. 48 cal. kyr BP is presented.
