Abstract: The main objective of the study is to describe as concisely as possible the oceanographic conditions of the Mozambique coastal waters. This could be of value for further hydrodynamic studies of coastal areas with particular emphasis on physical processes that most influence the coastal and marine resources, contributing for its sustainable management.

Abstract: Observing changes in the rise of relative sea level has resulted from the balance between the sea level rise due to the global warming of the planet, and the vertical displacements of the coast due to geological movements. The main objective of this paper is to outsource information about sea level monitoring in Mozambique, as part of a common global effort aiming to colect and analyse data that can help in understanding physical processes envolving ocean basins or oceans as a hole. Tidal stations at Maputo (lat. 25º 58.5’ S, lon. 32º 34.2’ E), Beira (lat.19º 49.4’ S, lon. 34º 50.0’ E), Quelimane (lat. 18º 00.3’ S lon. 36º 58.2’ E), Nacala (lat. 14º 27.8’ S, lon. 40º 40.8’ E), Inhambane (lat. 23º 52.0’ S, lon.35º 22.6’ E) Pemba (lat. 12º 58.0’ S, long. 40º 29.3’ E) has provided an important contribution in operational and research applications, being the last two stations, part of a global sea level observing network (GLOSS network). Consistent achievements as to the investigation of the sea level trends in the coast of Mozambique do not show up with evidence as yet, relying in the need for longer and uninterrupted time series, and subject to the application of improved quality control techniques. Pre-processing techniques were therefore developed in the Department of Oceanography of the national Institute of Hydrography and Navigation envisaging to exceed observed diversions in heights (use of cubic and lagrangian polynomials) and diversions in phase (use of Spline function). The effectiveness of these techniques is shown in some of the processed sea level plots presented on the panel. Tue, 01 Jan 2002 00:00:00 GMT http://hdl.handle.net/1834/191 2002-01-01T00:00:00Z
