Fig. 5.1: Schematic representation of various Maritime Zones
In one of the largest ever marine geophysical
surveys conducted by India, over 31,000 line
km of multi-channel seismic reflection, gravity
and magnetic data together with bathymetric
information were acquired along 42 predetermined
profiles. In addition, 100 Ocean
Bottom Seismometers (OBS) were deployed with
a significant retrieval rate of 92% and high quality
wide angle seismic reflection and refraction data
were obtained at critical locations.
The integration of the analytical results and their
documentation in accordance with the Scientific
and Technical Guidelines of the UN CLCS were
carried out at the National Centre for Antarctic and
Ocean Research (NCAOR) by a team of scientists
from several institutions. The final documents were
again reviewed by a Group of Experts constituted
by the Ministry of Earth Sciences. The entire
data has been organised on a suitably structured
RDBMS, as a centralised national facility.
On 11 th May, 2009, India filed to the CLCS, her
first partial submission under the provisions of
Article 76 for a continental shelf extending beyond
200 M from the Indian baselines (Fig. 5.2).
The Data Centre currently in an advanced stage
of development would describe the content,
format and access methodology with abundant
metadata describing the primary details in
terms of when and how the data was collected,
the nature of data collected, how the data was
processed, necessary supporting information
that went in to the processing, etc. The database
format is also planned to be flexible enough to
allow for both vertical and lateral growth. In
addition, it would facilitate: (i) migration of data
