At the expo NIO displayed
· Charismatic species of marine sea horses Hippocampus kuda, and a graphical interface showing different fish sounds with its frequency spectrum, corresponding fish clips, equipment’s used and the further on-going research to characterize species using the non-linear analysis techniques.
· Marine fossils, excellent indicators of past records of interactions between land, ocean and atmosphere including insolation, wind, sea water temperature and circulation, used to understand complex links between various climate components to help predict future changes. These were displayed under the microscope.
· Marine instrumentation display of new technologies for ocean observation that support the research capabilities at NIO, such as Autonomous Underwater Vehicle (AUV), Autonomous Vertical Profiler (AVP), Sea level Gauges. These instruments are applied in the fields of fisheries, climate change and pollution monitoring studies.
· Marine placer minerals and polymetallic nodules were exhibited as they are considered as commercially viable in future owing to their large extent and composition.
· Marine archaeological studies at the institute have provided evidences for overseas trade during historical periods from Goa and rich maritime practices of India. Stone Anchor and Lead Ingots artifacts were displayed.
· The model of the first indigenously built multi-disciplinary Research Vessel, Sindh Sadhana was displayed which turned out to be the major attraction of the stall.
