| Abstract | Simulation and interpretation of marine controlled-source electromagnetic (CSEM) data often approximate the transmitter source as an ideal horizontal electric dipole (HED) and assume that the receivers are located on a flat seabed. Actually, however, the transmitter dipole source will be rotated, tilted and deviated from the survey profile due to ocean currents. And free-fall receivers may be also rotated to some arbitrary horizontal orientation and located on sloping seafloor. In this paper, we investigate the effects of uncertainties in the transmitter tilt, transmitter rotation and transmitter deviation from the survey profile as well as in the receiver’s location and orientation on marine CSEM data. The model study shows that the uncertainties of all position and orientation parameters of both the transmitter and receivers can propagate into observed data uncertainties, but to a different extent. In interpreting marine data, field data uncertainties caused by the position and orientation uncertainties of both the transmitter and receivers need to be taken into account. |

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.
