Tapas Chowdhury â€“ Instructor of the Institute
At the outset, Mr. Chowdhury highlighted the unparalleled activities of the Institute round the year relating to river and sea and stated that this particular workshop is basically aimed at creating marine awareness and popularizing marine sports and adventure among the youth.
He enthused the audience to be well conversant with the enchanting and mesmerizing marine world, to which they were hitherto unexposed. Â He stated that only one-third of the worldâ€™s surface is land and the rest is made up of seas and oceans. Thus, the larger portion of the worldâ€™s life exists in water.
Subsequently, he dwelt upon water sports and adventure involving mainly scuba diving, white water rafting, kayaking etc. He also mentioned about natural disasters, such as earthquakes, landslides etc. to which mankind is exposed quite frequently and some effective rescue techniques to tackle such eventualities.
Mr. Chowdhury also gave a brief description of the Rowing and Sailing expedition from Kolkata to Andaman Islands organized by the Institute in early 2013 in commemoration of the 150th Birth Anniversary of Swami Vivekananda. The audience were spellbound on hearing about the thrilling moments of this expedition under his leadership. Six young and daring explorers had set out for this journey in a tiny un-propelled boat named â€œIndiraâ€ on 16th January 2013 and touched the shores of Port Blair on 3rd February 2013 overcoming the challenges posed by the mighty and furious waves of Bay of Bengal.
In conclusion, he stated about the Instituteâ€™s ensuing programmes for the year 2014-15 comprising of High Altitude Trekking Climbing (Gangotri-Gaumukh), Rafting expedition (Debaprayag-Haridwar) and Rowing Paddling expedition (Haridwar to Allahabad). In this context, he narrated the following main objectives of the expedition :
a)Â Â Â Â Â Â Â Â Monitoring water quality of different important places;
b)Â Â Â Â Â Â Â Â Photography of the ghats, temples, monuments etc. along the river bank with their proper documentation;
c)Â Â Â Â Â Â Â Â Study of the bank erosion along the river side; and
d)Â Â Â Â Â Â Â Â Study of the inhabitants along the river bank.
Soumen Das â€“ Trainer of the Institute
At the outset, Mr. Das stated that he is very much happy to have the privilege to speak about Disaster Management, being a trainer of the course â€˜Disaster Management (Marine) Life Saving and Rescue Operationâ€™ conducted by the Institute round the year.
He mentioned that â€˜Disaster Managementâ€™ may be regarded as one of the noblest services on earth. It is a humanitarian serviceÂ to â€œSave the life of a fellow human beingâ€.
He said that drowning of humans in water bodies such as tanks or pools or in tidal water and flood water is a very common disaster. The rescuer who is determined to save a drowning person must have a very stable mind. At the very moment of rescue, he exposes his own life to utmost danger. He has to face totally adverse situations. It is a common fact that the drowning person in tidal or flood waters would surround the neck of the rescuer firmly with his hands. At that crucial moment, the rescuer should adopt a few distinctive physical techniques to save his own life. These techniques are common for both swimmers and non-swimmers.
He further elaborated that normally for life saving, empty plastic bottles tied together, emergency rafts made of tied rubber tyres are used. Besides, a wooden cot turned upside down and covered with a polythene sheet is also used as a makeshift raft. These facilitate to extend all possible help to the victim.
Finally, he talked about the first aid to administered to a rescued person. He also emphasized on care to be given in case of cardiac attack and snake bites. In many cases it has been observed that a person rescued from flood water or tidal water or a victim of snake bite requires such special care. He added that if first aid is not enough, the victim should be immediately taken to the nearest hospital with the help of the local people.
His speech was backed by demonstration on stage and slide shows.
Koustav Chowdhury â€“ Eminent Navigational Astronomer associated with the Institute
Mr. Chowdhury commenced his speech by stating that Navigational Astronomy is a technique for determining the position in the high seas by observation of the identified stars, planets, the sun and the moon.
He further explained that anyone who is on a ship on the high seas, is far from the earthly landmarks. Though there are modern navigational aids like GPS, which depends on receiving data from a world wide network of artificial satellites, these may go wrong and mislead a sailor by providing erroneous messages. But nature never lies. He who can read the night sky can at least be aware of his location in the vast expanse of the sea. This signifies that knowledge of astronavigation is a must for every sea faring person. He also discussed briefly about the system of tidal effect, which solely depends on the solar system.
He mentioned that navigational astronomy is also known as astronavigation. He urged the youngsters to remember that â€˜Astronomyâ€™ is the oldest science and the sailors are the oldest astronomers indeed.
Finally, he talked about the sustained endeavour of mankind to know more about the planet â€˜Marsâ€™.
His speech was substantially backed by slide show.
