1. NATIONAL CENTRE FOR ANTARCTIC AND OCEAN RESEARCH Indian National Antarctic Data Center (INADC) 7 th September 2011 Indian Antarctic Data Centre Management of India National Centre for Antarctic and Ocean Research Ministry of Earth Sciences (Govt. of India) Headland Sada, Vasco da Gama, Goa-403 804

2. India’s National Antarctic Data Centre was established to provide a national facility to manage and disseminate scientific data resulting from Indian Antarctic research program in response to IPY Data Policy and Article III.1.c of the Antarctic Treaty. NCAOR has already designed a web-based Database for Metadata as per the format specified by Joint Committee on Antarctic Data Management (JCADM) and started its preliminary activity of collecting Metadata from the Scientific members of the XXVIII Indian Antarctic Expedition (2008-2009). Establishment of National Antarctic Data Centre at NCAOR

3. The Data Centre Website is based on a Three-tier architecture having a Front end, Middle end and Back end. We have used JSP + HTML as a Front End Tools, Apache Tomcat 6.0 App & Web server as a Middle Tier and PostgreSQL as a backend Database Establishment of National Antarctic Data Centre at NCAOR Data collecting Data processing Data quality emendation Data publishingData sharing Data use and reproduction Data preservation and archive Data Management

5. Progress The summarized information of all archived data (metadata) has been prepared by scientists to offer via data storage of the ‘INDIAN NATIONAL ANTARCTIC Data Centre’ (INADC), especially during the last four years. The compiled metadata comprises observational data from the Arctic, Antarctic and Southern Ocean regions on both Short-term and long term basis. The above ‘Science MetaData Base’ provided by INADC has tight collaboration (data linkage & exchange) with the Arctic & Antarctic Master Directories in the Global Change Master Directory (AMDs/GCMD). Metadata relating to IPY projects taken up by Indian scientists are being complied for hosting on IPY Portal in GCMD.

6. INADC is an authoritative platform for managing and sharing data of Indian polar science. It covers data from a broad spectrum of disciplines, including polar oceanography, polar solar-terrestrial physics, polar glaciology, polar resources and environmental science, polar biology and ecology, and polar atmospheric science, etc. It has become a characteristic center of “India’s Data-sharing Network of Earth System Science”. IADC Portal – Data-Sharing platform of Polar Science

7. Polar ice-snow, a carrier of global climate and environmental changes, plays an important role in the research on the global changes. Up till now all our previous Indian Scientific Expedition to Antarctica (ISEA) had successfully conducted studies on glaciers and snow ice chemistry from Antarctic & Arctic The metadata pertaining to these studies will form part of the Data Portal In addition the Data Portal will host atmospheric data from Arctic & Antarctic Data Portal

8. The NKN comprises of an ultra-high speed CORE (multiples of 10 Gbps), complimented with a distribution layer at appropriate speeds NCAOR is one of the participating institutions at the Edge will connect to the National Knowledge Network seamlessly at speeds of 1 Gbps. INDIA’S NADC will be migrated with NKN Internet. Migrating with National Knowledge Network (NKN)
