| Abstract | In September 2007 the Littoral Acoustic Demonstration Center (LADC), a consortium of University and Navy scientists, conducted an experiment in the northwest Gulf of Mexico to measure the three-dimensional acoustic field of the primary arrival from a seismic airgun array. The water depth was approximately 1500 m. The acoustic measurements were made by Generation 2 4-channel EARS (Environmental Acoustic Recording System) buoys developed by the Naval Oceanographic Office (NAVOCEANO), with each channel capable of measuring to 25 kHz. A total of 48 hydrophones were deployed on 3 moorings at 20 different depths. At each depth there was a sensitive and desensitized phone, the latter used to prevent clipping. Eight hydrophones (four pairs) were ship-deployed near the surface. A dedicated source ship, the M/V Fairfield ENDEAVOR, supplied almost all the shots, although the M/V Veritas VANTAGE, which was conducting a survey in the area, provided a few lines of opportunity. The M/V CAPE HATTERAS was used to deploy, manage, and recover the receiving hydrophone arrays, as well as to conduct all environmental measurements. It also deployed and provided communication and control for the Ultra Short BaseLine Localization (USBL) system and a single Acoustic Doppler Current Profiler (ADCP), which were used to give accurate hydrophone positions during the experiment. About 3.5 TB of data were collected. |

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.
