Unpicking the Anthropocene in the Hawaiian Archipelago

海洋岛屿通常被视为全球变暖影响的关键早期指标或缩影，但它们也受到更广泛的人类影响的影响，包括入侵物种的引入、加速的土壤侵蚀和污染。这种加速的人类影响，特别是在20世纪50年代全球人为影响的“大加速”期间(拟议的人类世时代的开始)，在更早的人类影响和自然环境变化的几个世纪中被重叠。当地的沉积系统记录了这些变化在形态、沉积物、化学和化石方面的证据，是较长期和较新的人类影响和环境变化的关键档案。该项目将研究夏威夷群岛周围最近沉积沉积物的使用，以确定推定的人类世，并将其与早期的沉积、地球化学和生物变异性区分开来。

Oceanic islands are often regarded as key early indicators or microcosms of the impacts of global heating, but they also are impacted by a wider range of human impacts, including introduction of invasive species, accelerated soil erosion, and pollution. This accelerated human impact, particularly from the 1950s during the "Great Acceleration" of global anthropogenic impacts (the beginning of the proposed Anthropocene epoch), is overprinted however on centuries of earlier human impact and natural environmental change. Local sedimentary systems record evidence of these changes in their morphology,sediments, chemistry and fossils, and are key archives of longer-term and more recent human impacts and environmental changes. This project will examine the use of recent sedimentary deposits from around the Hawaiian archipelago in identifying the putative Anthropocene, and distinguishing it from earlier sedimentary, geochemical and biological variability.
