Impact of Research Activities on McMurdo Dry Valley Lakes

项目工作人员建议支持该研讨会提案，该提案根据NSF手册10,122.1.1 .c.3.b免除同行评审。该提案将支持一个研讨会，以解决科学研究对南极洲麦克默多干谷常年冰雪覆盖的湖泊的影响。就该讲习班的相关性咨询了环境干事Joyce Jatko；她支持为其提供资金。这次邀请研讨会将汇集约35名专家，不仅来自极地湖沼学界，而且来自更广泛的水生界。该研讨会讨论了科学界、美国国家科学基金会项目工作人员、美国非政府组织和国际南极社区一直关注的重要问题。受邀参与者名单根据科学学科适当平衡，并包括重要的国际科学家。方案工作人员与项目负责人讨论了拟议参与者名单中缺乏性别平衡的问题，项目负责人向工作人员保证将实现更适当的平衡。讲习班的结果将作为一份报告提供，以便广泛分发。这份报告不仅对科学家有用，而且对南极项目的管理者也有用，因为他们必须确保在南极洲进行的活动得到审查，以符合《南极条约环境保护议定书》的意图。DORAN南极洲维多利亚地南部麦克默多干谷的常年被冰覆盖的湖泊，自从1903年被罗伯特·法尔肯·斯科特发现以来，一直是研究的对象。这些干谷湖在地球上是独一无二的，科学界对最大限度地保护它们的原始自然状态非常感兴趣。该奖项将支持一个邀请讲习班，该讲习班将汇集大约35名在水生环境方面具有专业知识的科学家。讲习班的目的是评估过去和目前在干河谷湖泊及其周围进行的研究活动的影响。该小组将就确定可接受的影响水平以及以对环境负责的方式管理未来研究活动的方法提出建议。鉴于这些湖泊的独特性和科学价值，研讨会的参与者将从南极和北极科学家以及更广泛的水生科学界的调查人员中选择。讲习班与会者将讨论研究活动对南极湖泊的潜在影响，包括冰洞融化、水肺潜水、遥控和自主操作的水下航行器、化学示踪剂的使用、重复的水采样、废物清除和沉积物取心。探讨了岸基研究和冰川融水流研究对干谷湖泊的影响。对人类对地球环境影响问题的一个方面采取这种严肃的态度，应当提供关键的资料，以帮助指导和指导今后的科学活动。

Diary Note OPP-0732029 Program staff recommend support of this workshop proposal, which is exempt from peer review per NSF Manual 10, 122.1.c.3.b. The proposal will support a workshop to address the impact of scientific research on the perennially ice- covered lakes of the McMurdo Dry Valleys, Antarctica. The Environmental Officer, Joyce Jatko, was consulted as to the relevance of this workshop; she endorsed its funding. This invitational workshop will bring together about 35 experts from not only the polar limnology community but from the broader aquatic community. The workshop addresses important issues, which have been the focus of question or concern by the scientific community, program staff at NSF, the US non-governmental community and the international Antarctic community. The invited participant list is appropriately balanced by scientific discipline and includes the key international scientists. Program staff discussed the lack of gender balance in the proposed list of participants with the PIs, who have assured staff that a more appropriate balance will be achieved. The results of the workshop will be made available as a report, to be widely distributed. The report will be useful not only to scientists, but to managers of Antarctic programs who must ensure that activities conducted in Antarctica are reviewed to meet the intent of the Protocol on Environmental Protection to the Antarctic Treaty. 9732029 DORAN The perennially ice-covered lakes of the McMurdo Dry Valleys in southern Victoria Land, Antarctica, have been the object of study since their discovery by Robert Falcon Scott in 1903. These dry valley lakes are unique on Earth, and there is great interest within the scientific community to preserve their pristine nature to the maximum extent possible. This award will support an invitational workshop which will bring together about thirty-five scientists with expe rtise in aquatic environments. The purpose of the workshop is to assess the impact of past and current research activities in and around the dry valley lakes. The group will make recommendations on the establishment of acceptable levels of impact as well as on approaches to management of future research activities in an environmentally responsible manner. Given the uniqueness and scientifically valuable nature of these lakes, workshop participants will be chosen from the pool of Antarctic and Arctic scientists as well as from investigators in the broader aquatic sciences community. Workshop participants will address the potential impacts of research activities on the Antarctic lakes, including ice-hole melting, SCUBA diving, remotely-operated and autonomously-operated underwater vehicles, the use of chemical tracers, repetitive water sampling, waster removal and sediment coring. The impact of shore-based and glacier melt stream research activities on the dry valley lakes will also be explored. This serious approach to one aspect of the issue of human impact to the Earth's environment should provide critical information to help guide and direct future scientific activities.
