Increased frequency, severity, and extent of disturbances such as beetle outbreaks, catastrophic fires, windstorms, and droughts, have caused widespread concern about ecosystem health. Because the consequences of disturbance can take many years to play out, evaluation of their potential impacts is difficult without a baseline record of ecosystem processes that spans decades to a few thousand years. Two groups of scientists, ecosystem ecologists and paleoecologists, study these processes, but they typically examine events and consequences on different time scales. Researchers from each group will be brought together to characterize past ecosystems in a PROBE (Paleo Reconstructions Of Biogeochemical Environments) workshop, where several datasets, including sediment records, tree-ring records, soil records, and long-term instrumental measurements will be examined to assess how ecosystem processes (particularly carbon and nitrogen cycling) have responded to disturbance. The PROBE workshop will benefit society and the larger scientific community. The workshop will include early career participants, providing opportunities to train young scientists how to conduct collaborative and interdisciplinary research that is needed for the 21st century. Several participants have developed specialized techniques such as charcoal analysis and stable isotope interpretation and knowledge of these techniques will be shared at the workshop. Finally, several participants are working with government agencies and NGOs to provide information about the effects of disturbance, especially insect outbreaks and wildland fire management. The workshop will provide information that will be helpful to managers, particularly those trying to develop strategies for dealing with disturbances.

增加的频率，严重程度和程度的障碍（例如甲虫暴发，灾难性的火灾，风暴和干旱）引起了人们对生态系统健康的广泛关注。由于干扰的后果可能需要多年的时间才能发挥作用，因此，如果没有数十年到几千年的生态系统过程的基线记录，对其潜在影响的评估很难。两组科学家，生态系统生态学家和古生物学家研究了这些过程，但它们通常会检查不同时间尺度的事件和后果。每个小组的研究人员都将聚集在一起，以探测器（生物地球化学环境的古重建）研讨会来表征过去的生态系统，其中几个数据集，包括沉积物记录，树木环记录，土壤记录和长期工具测量，以评估生态系统过程（尤其是碳和氮气和氮气循环），以评估生态系统过程（尤其是）。调查研讨会将使社会和更大的科学界受益。该研讨会将包括早期职业参与者，为培训年轻科学家的机会提供机会如何进行21世纪所需的合作和跨学科研究。一些参与者开发了专业技术，例如木炭分析和稳定的同位素解释，这些技术的知识将在研讨会上共享。最后，几名参与者正在与政府机构和非政府组织合作，以提供有关干扰影响的信息，尤其是昆虫爆发和野外火灾管理。研讨会将提供对经理有帮助的信息，尤其是那些试图制定处理干扰策略的人。
