| Abstract | An Ocean Observatory is being deployed in Bonne Bay, a fjord on the west coast of Newfoundland, in Fall 2003, by Memorial University of Newfoundland, to understand the influence of the physical environment on the temporal variability of marine ecosystems. The Observatory provides investigators scheduled and interactively managed real time data acquisition and control of the network of sensors. Serving a multidisciplinary team, the instrument array is diverse, including acoustic sensors to determine currents, bubble distribution and plankton abundance, video to determine plankton and benthos species abundance, and sensors for temperature, salinity, chlorophyll fluorescence, carbon dioxide, oxygen and inorganic nutrient concentrations and spectral irradiance. The control and telemetry system is comprised of a power distribution subsystem and TCP/IP based network consisting of two Ethernet local area networks, one on shore linking data acquisition and control computers and one underwater connecting the sensors, joined by an armored 1.5 km electrooptic cable. The system is designed to be modular, accommodating guest instruments at spare Ethernet and serial ports. The paper describes the functional requirements, the software and network architectures, and the physical implementation of the ocean observatory. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
