Interagency Agreement No. NPS-IA-1100-9-0001/DPP89-12135 Modification No. 3

自1986年以来，公众对南极洲的兴趣急剧增加。作为回应，商业旅游经营者扩大了他们的南极业务，特别是在南极半岛地区。由于许多游客是美国公民，访问美国南极站的需求也有所增加。作为美国国家南极项目的管理者，美国国家科学基金会正试图在不对研究项目产生重大影响的情况下满足纳税人游客的需求。由于国家公园管理局在规划和管理美国各地公园和其他地点的游客方面拥有丰富的经验，美国国家科学基金会寻求他们的帮助，制定计划，使游客能够非正式地进入美国站，而不会增加美国在南极洲有限资源的压力。根据这份机构间协议的条款，国家公园管理局将帮助国家公园基金会制定、计划和呈现解说节目和其他游客活动，并将向国家公园基金会提供以下内容：1、向参观帕尔默站的游客播放一盘录像带（大约15分钟长）。1990年1月至3月期间在帕尔默站提供口译服务。O由两个机构确定的规划和其他服务。

Since 1986, public interest in Antarctica has increased dramatically. In response commercial tour operators have expanded their antarctic operations, particularly in the Antarctic Peninsula region. Because many of the tourists are U.S. citizens, the demand for visits to U.S. Antarctic Stations also has increased. The National Science Foundation, as manager of the U.S. national program in Antarctica, is attempting to meet the demands of taxpaying tourists without significant impact to the research program. Because the National Park Service has extensive experience in planning and managing tourists at parks and other sites throughout the United States, NSF has sought their assistance to develop programs that will provide tourists with informal access to U.S. stations without increasing pressures on limited U.S. resources in Antarctica. Under the terms of this interagency agreement, the National Park Service will help NSF formulate, plan, and present interpretive programs and other visitor activities and will provide NSF with the following: o a video tape (approximately 15 minutes long) to be shown to tourists visiting Palmer Station. o interpreter services at Palmer Station between January and March 1990. o planning and other services as determined by both agencies.
