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.

海洋岛通常被视为全球供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，包括引入入侵物种，加速的土壤侵蚀和污染。这种加速的人类影响，尤其是从1950年代开始的全球人为影响的“巨大加速”（拟议的人类世时代的开始），但在几个世纪以前的人类影响力和自然环境变化中都被过多地宣传。当地沉积系统记录了其形态，沉积物，化学和化石的这些变化的证据，并且是长期和最新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附近的最近的沉积沉积物来识别假定的人类世，并将其与早期沉积物，地球化学和生物学变异性区分开来。
