The Kejimkujik Watershed Study (KWS) was initiated in 1978 in response to growing concerns about the possible harmful effects on the environment of long range transport of air pollutants, particularly acid rain. It is one of five calibrated watershed studies in Canada that represent a range of climatic conditions, terrain sensitivities, and rates of atmospheric acidic deposition. This report presents the proceedings of a workshop on the study, covering programs and concepts in integrated monitoring and research; monitoring global change; research and monitoring in and around Kejimkujik National Park; monitoring and research of surface waters, lakes and streams, and forests and watersheds; and the organization and interpretation of Kejimkujik research station establishment. Summary reports are given on watershed studies in the Experimental Ponds Area of Newfoundland, the Integrated Forest Studies Cooperative in Vermont, and the Humic Lake acidification experiment in Norway. Highlights of an open discussion on future activities are also included.

This set of papers presents a description of the synthesis of hydrological problems and various environmental implications and management strategies for different highland and headwater regions of the world. Regions covered include the Himalayas, Russian mountains, Amazonia, and upland Wales.

A workshop was held to explore the need for an ecological research and monitoring site in the Atlantic Maritime Ecozone, with particular reference to the land/sea/atmospheric interface (coastal zone), and to explore the suitability of the Huntsman Marine Science Centre, in conjunction with the Fisheries and Oceans Canada Biological Station, as the administrative center of such a site. This publication presents summaries of the working group discussions on estuarine and marine ecosystems, terrestrial and aquatic ecosystems, and ecosystems data management, and includes papers presented at the workshop. The topics of the papers include ecosystem and wildlife monitoring, atmospheric variables and trees, research and monitoring programs, sulfur dioxide deposition, lakewater chemistry, benthic monitoring, and nutrient cycling patterns.
