In this paper a process for the detection of clusters in oceanographic data is described. The application to oceanographic data is relevant as it allows the improvement of the understanding of the phenomena occurring in the Portuguese coast. Additionally, the application also illustrates how the self-organizing maps maybe used to explore and explain clusters, especially emphasizing the relevanc...

The importance of tracking the provenance of electronic data becomes apparent when data set providers need to also provide metadata describing where the data came from. This need has driven the development of a practical oceanographic data provenance system at the Monterey Bay Aquarium Research Institute. MBARI’s Shore Side Data System is designed to manage data collected, processed, and archiv...

Our long-term goal is to provide the fundamental mapping information and visualization tools necessary to support STRATAFORM's multidisciplinary effort to develop a more complete understanding of how short-term oceanographic and geological processes interact to produce the preserved geologic record on the shelf and slope portions of the continental margins. This effort began with detailed mappi...

The influence of environmental variables (oceanographic and climatic) on the catch rates striped red mullet (Mullus surmuletus) by artisanal fishery was investigated using different time series models (Dynamic Factorial Analyses; Min-Max Analyses Generalized Least Square models). Climatic oceanographic survey data were collected at areas Portuguese coast (Northwestern, Southwestern South-Algarv...

The Mapping, Charting and Geodesy Branch of the Naval Research Laboratory at Stennis Space Center, Mississippi. is conducting a multi-year program for the development of unmanned, untethered sensor systems for the collection of tactical oceanographic data in littoral regions. The primary function of this program is the development of immediate force-multiplying survey capabilities for the colle...

A new oceanographic measurement concept, Acousti-cally Focused Ocean Sampling-AFOS, is presented, combining a tomographic network with small autonomous underwater vehicles. Using wireless local area network technology, the acoustic tomography data are recorded and processed in real time for achieving a low-resolution estimate of oceanographic parameters. The results are used to focus direct mea...
