IndARC

On 23rd July, 2014 when a team of scientists from the ESSO-National Centre for Antarctic and Ocean Research (NCAOR) and the ESSO-National Institute of Ocean Technology (NIOT) successfully deployed IndARC, the country’s first multi-sensor moored observatory in the Kongsfjorden fjord of the Arctic, roughly half way between Norway and the North Pole. This moored observatory, designed and developed by ESSO-NIOT and ESSO-NCAOR with ESSO-Indian National Centre for Ocean Information Services (INCOIS) was deployed from the Norwegian Polar Institute's research vessel R.V. Lance during its annual MOSJ-ICE cruise to the Kongsfjorden area. 

The observatory is presently anchored (78°57´ N 12°01´E), about 1100 km away from the North Pole at a depth of 192 m and has an array of ten state-of-the-art oceanographic sensors strategically positioned at discrete depths in the water column. These sensors are programmed to collect real-time data on seawater temperature, salinity, current and other vital parameters of the fjord.

The Kongsfjorden is an established reference site for the Arctic marine studies. The Kongsfjorden has been considered as a natural laboratory for studying the Arctic climate variability, as it receives varying climatic signals from the Arcitc/Atlantic in the course of an annual seasonal cycle. ESSO-NCAOR has been continuously monitoring the Kongsfjorden since 2010 for understanding response of the fjord to climate variability at different time scales. The temperature and salinity profiles of the fjord, water column nutrients and diversity of biota are being monitored at close spatio-temporal scales throughout the spring-summer-fall seasons. There exists a great need to know on how the fjord system is influenced by, or responds to exchanges with the water on the shelf and in the deep sea outside during an entire annual seasonal cycle. In particular, there is a need for continuous observations of the water transport into the interior part of the fjord. One of the major constraints in such a study has been the difficulty in reaching the location during the harsh Arctic winter and obtaining near-surface data. 

The IndARC observatory is an attempt to overcome this lacuna and collect continuous data from depths very close to the water surface as well as at different discrete depths. The data acquired would be of vital importance to the Indian climate researchers as well as to the international fraternity. In addition to providing for an increased understanding of the response of the Arctic to climatic variabilities, the data would also provide a good handle in our understanding of the Arctic processes and their influence on the Indian monsoon system through climate modelling studies.

The deployment of the country’s first polar mooring is a testimony to the capabilities of the ESSO in designing, developing and installing underwater observatories. The technical and logistics support extended by the Norwegian Polar Institute, is a good example of the increasing scientific and technical co-operation between India and Norway in addressing the global climate change.

कर्ण और कृष्ण का संवाद - रामधारी सिंह 'दिनकर'

Following is excerpt from poem Rashmirathi written by Ram dhari singh dinkar. Karna reply to Krishna when he told story of his birth and ask him to join pandava side. सुन-सुन कर कर्ण अधीर हुआ, क्षण एक तनिक गंभीर हुआ,  फिर कहा "बड़ी यह माया है, जो कुछ आपने बताया है  दिनमणि से सुनकर वही कथा मैं भोग चुका हूँ ग्लानि व्यथा  मैं ध्यान जन्म का धरता हूँ, उन्मन यह सोचा करता हूँ,  कैसी होगी वह माँ कराल, निज तन से जो शिशु को निकाल  धाराओं में धर आती है, अथवा जीवित दफनाती है?  सेवती मास दस तक जिसको, पालती उदर में रख जिसको,  जीवन का अंश खिलाती है, अन्तर का रुधिर पिलाती है  आती फिर उसको फ़ेंक कहीं, नागिन होगी वह नारि नहीं  हे कृष्ण आप चुप ही रहिये, इस पर न अधिक कुछ भी कहिये  सुनना न चाहते तनिक श्रवण, जिस माँ ने मेरा किया जनन  वह नहीं नारि कुल्पाली थी, सर्पिणी परम विकराली थी  पत्थर समान उसका हिय था, सुत से समाज बढ़ कर प्रिय था  गोदी में आग लगा कर के, मेरा कुल-वंश छिपा कर के  दुश्मन का उसने काम किया, माताओं को बदनाम किया  माँ का पय भी न पीया मैंने, उलटे अभिशाप लिया मैंने  वह तो यशस्विनी बनी रह

एक पुलिसवाले की व्यथा

लोग अक्सर कहते हैं कि पुलिस सही तरीके से क्राइम कंट्रोल नहीं करती है लेकिन पुलिस करे तो करे क्या। उग्र भीड़ को क्राइम कंट्रोल करने पर आधारित एक लघु कथा। उन्मादी भीड़ हाथों में नंगी तलवारें, लाठी, डंडे लिए पागलों की तरह पुलिस वालों को पत्थर मार मार कर खदेड़ रही थी। उसकी पुलिस भीड़ से अपना असलाह और खुद को बचाते हुए पीछे हट रही थी। थानेदार का सर बुरी तरह फूट गया दो सिपाही उसे सँभालते हुए पीछे हट रहे थे बड़े अफसर, एस डी ऍम, सब मौके से गायब थे। ऑर्रडर देने वाला कोई दूर दूर तक नहीं था। भीड़ हावी होती जा रही थी। सब को कहीं न कही चोट लगी थी।भीड़ को लाठी डंडो से काबू करने के हालात तो बिलकुल भी नहीं थे। सबकी जान पर बनी हुई थी परंतु हाथ में लोड राइफल होते हुए भी जवान गोली चलाने से बच रहे थे, कैसी कायर स्तिथि थी। अचानक हवलदार बुधना को भीड़ ने पकड़ लिया और एक आदमी ने बुधना के सर पर कैरोसिन की गैलन उंडेल दी और दूसरे ने माचिस निकाली ही थी की धाँय की आवाज हुई और माचिस वाला जमीं पर लुढकने लगा।दूसरी आवाज में तेल के गैलन वाला जमीं पर कला बाजी खा रहा था । भीड़ जहां थी वहीँ थम गयी और उलटे पावँ भागने लगी लेकिन......अ

Scheme for creation of National Optical Fiber Network for Broadband connectivity of Panchayats

The Union Cabinet recently approved a scheme for creation of a National Optical Fiber Network (NOFN) for providing Broadband connectivity to Panchayats. The objective of the scheme is to extend the existing optical fiber network which is available up to district / block HQ’s level to the Gram Panchayat level initially by utilizing the Universal Service Obligation Fund (USOF). The cost of this initial phase of the NOFN scheme is likely to be about Rs.20,000 crore. A similar amount of investment is likely to be made by the private sector complementing the NOFN infrastructure while providing services to individual users. In economic terms, the benefits from the scheme are expected through additional employment, e-education, e-health, e-agriculture etc. and reduction in migration of rural population to urban areas. As per a study conducted by the World Bank, with every 10% increase in broadband penetration, there is an increase in GDP growth by 1.4%. NOFN will also facilitate implemen

Analysis of Civil Services Prelims paper ( CSAT ) 2011

Anyone who is following the recent trends of civil services prelims papers , can easily predict the unpredictable nature of the paper . Also since this year CSAT has been introduced for the first time every one was curious to see the prelims paper of this year . Atlast today on 12th june suspense ended and what we found was more unpredictable than predictable .I will do paper wise analysis Paper 1 : The topics which came in paper was very much on predictable line . It was very specifically written in UPSC syllabus "General issues on Environmental ecology, Bio-diversity and Climate Change - that do not require subject specialization" , though question have always been asked from these topics but since UPSC mentioned it as separate topic this year , few questions were expected form this topic . Similarly few questions were expected from the Economics , Polity , International affairs , general science and History as well . But then , with UPSC one can never expect que
