项目摘要
Collaborative Research: RUI: Sensitivity of Circum-Arctic Peatland Carbon to Holocene Warm Climates and Climate Seasonality (PIs: Zicheng Yu, David Beilman, and Philip Camill) Recent accelerated Arctic warming has caused widespread changes in terrestrial ecosystems, including carbon dynamics. Past climate warming and documented ecosystem responses provide crucial insights from Earth?s history for understanding and projecting possible responses to future climate change. In this project, researchers from Lehigh University, University of Hawaii and Bowdoin College will evaluate the outcomes of ?natural climate-warming experiments? that have occurred across the Arctic over the Holocene (the last 12,000 years). They will focus on two warm climate intervals: (1) the Holocene Thermal Maximum ranging in timings between 10,000 and 6000 years ago, and (2) the warm Medieval Climate Anomaly around 1000 years ago. The funds were requested (1) to collect new samples from carbon-rich peatlands from several critical regions (including Alaska, Mackenzie Basin, Hudson Bay Lowlands, Labrador, and Kamchatka), (2) to carry out integration and synthesis of available data, and (3) to work on climate-carbon modeling experiments along with their collaborators. The idea that both temperature and climate seasonality are dominant controls of carbon balances in carbon-rich Arctic ecosystems has important implications for projecting the fate of Arctic carbon in the future, as future warming is expected mainly in the winter season. Other broader impacts include (1) the support of new faculty career development, (2) training of undergraduate students, graduate students, and a postdoctoral fellow, emphasizing groups traditionally underrepresented in the natural sciences, (3) international collaborations and training through two workshops, and (4) public outreach through a symposium on Arctic climate change and soil carbon dynamics and the development of long-term exhibits at the Peary-MacMillan Arctic Museum at Bowdoin College.
合作研究:- 我知道环北极泥炭地碳对全新世温暖气候和气候季节性的敏感性(PI:Zicheng Yu,大卫Beilman,和Philip Camill)最近加速的北极变暖引起了陆地生态系统的广泛变化,包括碳动态。过去的气候变暖和记录的生态系统反应提供了来自地球的重要见解?的历史,了解和预测可能的应对未来气候变化。在这个项目中,来自利哈伊大学,夏威夷大学和鲍登学院的研究人员将评估的结果?自然气候变暖实验在全新世(过去的12,000年)发生在整个北极地区。他们将重点关注两个温暖的气候间隔:(1)全新世热最大范围的时间范围在10,000和6000年前,和(2)温暖的中世纪气候异常约1000年前。申请资金的目的是:(1)从几个关键地区(包括阿拉斯加、麦肯齐盆地、哈德逊湾低地、拉布拉多半岛和堪察加半岛)的富碳泥炭地收集新样本;(2)对现有数据进行整合和综合;(3)与合作者一起沿着气候-碳模拟实验。温度和气候季节性是富碳北极生态系统碳平衡的主要控制因素,这一观点对预测北极碳的未来命运具有重要意义,因为预计未来变暖主要发生在冬季。其他更广泛的影响包括(1)支持新教师的职业发展,(2)培训本科生,研究生和博士后研究员,强调传统上在自然科学中代表性不足的群体,(3)通过两个研讨会进行国际合作和培训,以及(4)通过北极气候变化和土壤碳动力学研讨会以及在鲍登学院的Peary-MacMillan北极博物馆开发长期展览来进行公众宣传。
