General characteristics Main influences ... Bibliography Summary The Baltic is the largest brackish water system in the world. Its only connection to more open seas are the shallow sounds between Sweden and Denmark. The sea is slowly shrinking because of geological uplifting of land after the last glaciation. In many respects the Baltic is similar to an inland lake or an estuary. It is unique in that there are areas where freshwater, brackish water and marine species are all present. Its salinity increases from east to west and from north to south. The marked vertical and horizontal salinity gradients are reflected in different species communities and species numbers. The highest biodiversity is found in the south-west of the Baltic Sea.

Rivers in the Southern Ocean One of the main characteristics of the Southern Ocean resides in the fact that it is a major source of cold water production (by the formation of some 20 million square kilometres of ice floe per year) and therefore The cold and dense water of the Antarctic - the " Antarctic Bottom Water " - is not the only water travelling in the oceans of the world. Above the deep layers that circulate at a depth of more than 4,000 metres, oceanographic soundings have found "deep circumpolar water" at a depth of less than 3,000 metres regulating the movements of the Southern Ocean. This a huge (very saline) water mass formed in the high latitudes of the Northern Hemisphere that wends its way towards the south. The surfacing of this warmer northern water (its temperature is on average 2 to 3°C higher than the cold water at the bottom) in the Antarctic polar regions is helped by the meeting of the westerly and easterly winds - the zone of Antarctic divergence - which often force the surface Antarctic water to divide in two, one part going northwards and the other towards the coasts. This perpetual toing and froing of water coming from different horizons and meeting in the Antarctic Ocean contributes, rather like the circulation of the atmospheric air mass, to the planet's climatic equilibrium.

Advisory Committee Members: Professors Blanco (Spanish and Portuguese), Seidman (Sociology), Carter (Agricultural and Applied Economics), Fair (Journalism and Mass Communication) Undergraduate adviser in the major: Christine Schindler, 226 Ingraham Hall, 262-8431, The international studies major offers a broad background in international and transnational political, social, economic, commercial, and environmental affairs, together with a comparative study of politics, economics, security, and culture. The goal is to provide students with the necessary tools to understand global processes in their totality and how they are situated and lived in specific regions. It is important to stress that the major itself is not primarily vocational or professional. It does, however, provide an integrated program of courses which lays the foundation for professional training in a wide variety of areas. Such a foundation can be invaluable in securing a place in competitive graduate or professional schools, which, in turn, prepare an individual for government service, or for other careers with an international focus, including those in multinational corporations, international banking houses, foreign press services, and institutions of teaching and research.

1. The climate change - Agriculture conundrum WIM G. SOMBROEK Land and Water Development Division, and Interdepartmental Working Group on Climate Change, FAO, Rome, Italy Agrometeorology Group (Environmental Information Management Service), and Interdepartmental Working Group on Climate Change, FAO, Rome, Italy The world agricultural context The changing agricultural environment Plant physiological direct effects The hydrological cycle and soils ... References The risks associated with climate change lie in the interaction of several systems with many variables that must be collectively considered. Agriculture (including crop agriculture, animal husbandry, forestry and fisheries) can be defined as one of the systems, and climate the other. If these systems are treated independently, this would lead to an approach which is too fragmentary. The issue is more global. It is now held as likely that human activities can affect climate, one of the components of the environment. Climate in turn affects agriculture, the source of all food consumed by human beings and domestic animals. It must be further considered that not only climate may be changing, but that human societies and agriculture develop trends and constraints of their own which climate change impact studies must take into consideration. An expert meeting held at FAO Headquarters in Rome from 7 to 10 December 1993 considered the direct effects of changing hydrological, pedological and plant physiological processes on agricultural production and concentrated on mechanisms. This introductory chapter of its Proceedings looks beyond the technical aspects of agriculture and stresses some of the major goals of FAO.

The lidar has been successfully tested and operated outside Buenos Aires. At the same time, in cooperation with France, an ozone lidar is currently being built. An informal meeting of scientific groups involved in SPARC-related activities was held in December 1995 in the Universidad de Buenos Aires. The Servicio Meteorologico Nacional (SMN), jointly with the province of Tierra del Fuego, continues the operation of the GAW station near Ushuaia. Also, a column NO sensor measurements here as well as at Marambio St. Other activities such as the NSF-CONICET high resolution spectrophotometer at Ushuaia and the national UV-monitoring network, with 5 GUV-511 continue normal operations.
