An inexpensive method for calibrating an infrared analyzer to measure varying ranges of carbon dioxide partial pressures (Pco₂) is described. A discussion is made of the hydrographic (temperature, salinity, and sigma-t) and chemical (dissolved oxygen, AOU, Pco₂ pH, and nutrients) variables that were observed along the Newport hydrographic line in March and June 1971. A winter storm in late March led to an inshore feature of doming isolines. Indications of early seasonal upwelling and photosynthesis were also observed. June conditions were characterized by a deteriorated upwelling regime and an inshore phytoplankton bloom. The Columbia River plume was also driven abnormally close (65 kilometers) to shore by southwesterly winds. Chemical variables as observed in the Columbia and Willamette Rivers in June, 1971 are compared to data from a study made in December, 1968. A large gradient in Pco₂ and temperature is observed in the Willamette River approximately 3.5 kilometers upstream from the confluence in June, but not in December. This observation is related to the seasonal flow patterns of the two rivers. Chemical variables in the Columbia River are influenced by seasonal phytoplankton activity, but oxidation of organic matter is the predominating factor in the Willamette River. Pco₂ values calculated from pH and alkalinity measurements agreed to ± 5 percent with directly measured Pco₂ values in the Columbia River. / Graduation date: 1973

Os documentos apresentados no PDPA deveriam permitir ao setor público lidar com duas variáveis de difícil tratamento isto é, a preservação do manancial hídrico e a expansão urbana, indicando pressupostos que orientariam os programas de recuperação da Bacia Hidrográfica do Guarapiranga. Em decorrência destes pressupostos destacados no capítulo 4 - item 4.1, o Plano de Desenvolvimento e Proteção Ambiental - PDPA, lidou com questões múltiplas atinentes ao uso e ocupação do solo da Bacia do Guarapiranga e à qualidade das águas de seus tributários e é sobre este documento que o trabalho, ora desenvolvido, analisa as ações propostas. Sempre com a visão crítica e, apesar da inegável qualidade deste plano, propondo reunir organizações públicas diversas, de esferas administrativas diferentes, com relevantes aspectos de ações dependentes de esforços combinados de dois ou mais executores, o PDPA, apesar da vanguarda nestas ações deixou alguns desafios a vencer e, mais ainda, lições que devem ser objeto de discussões e comentários, visando à sua absorção no caso de novos projetos semelhantes ao Guarapiranga. Portanto, este trabalho de dissertação apresenta, dentro do âmbito deste plano de recuperação ambiental, uma avaliação dos principais requisitos para uma ordenação do uso compatível com as condições da bacia hidrográfica, cujo principal objetivo é o abastecimento público de água de 3 milhões de habitantes. / The Plan of Development and Environmental Protection - PDPA, was elaborated to guide action in the brainstorming to preserve an indispensable source to the public supplying of the Region Metropolitan of São Paulo. The documents presented in the PDPA would have to allow the public sector to deal with two variable of difficult treatment that is, the preservation of the hydric source and the urban expansion, indicating estimated that they would guide the programs of recovery of the Hydrogeographic Basin of the Guarapiranga. In result of these estimated detached in the chapter 4 - item 4.1, the Plan of Development and Environmental Protection - PDPA, it dealt with multiple questions to the use and occupation of the ground of the basin of the Guarapiranga and to the quality of waters of its tributaries and is on this document that the work, however developed, analyzes the actions proposals. Always with critical vision and despite the undeniable quality of this plan, considering congregating public organizations diverse, of different administrative spheres, with excellent aspects of dependent actions of agreed efforts of two or more executors, the PDPA, despite the vanguard in these actions left some challenges to win e, more still, lessons that must be objects of quarrels and commentaries aiming at to its absorption in the case of new similar projects to the Guarapiranga. Therefore, this work of dissertation inside aims at of the scope of this plan of environment recovery to evaluate if the same it took care of to the main requirements for an ordinance of the compatible use with the conditions of the hydraulic basin, whose main objective is water the public supplying of 3 million inhabitants.
