Oceanography


The deep green sea holds many secrets in its breast - and has fascinated men and women down the ages. Its mysterious depths appear to call on men to explore, understand and expose its mystery.

If you are also lured by the siren call, then oceanography is what you should look at seriously.

Oceanography, as the name suggests, focuses on the ocean and its related activities. It includes within its ambit a wide array of disciplines - physical, chemical, biological, geophysical, ocean engineering, marine biology and geotechnology.

Physical oceanography, deals with the movements of the ocean water - wave motions, tides, currents and temperature and density of seawater. It studies the influence of atmosphere on weather and climate globally, transmission of light and sound through water, and the ocean’s physical interaction with the seafloor and the coastline.

chem.jpg (3703 bytes) Chemical oceanography studies the chemical composition and properties of seawater. It analyses seawater components, various dissolve and suspended organic and inorganic materials, salinity and the effects of pollutants. It also examines chemical processes operating within the marine environment. It helps in understanding the movements of ocean currents around the globe and their effect on the climate.
Biological oceanography is concerned with the diverse forms of ocean life. It studies the evolution adaptation, survival and interaction of marine life with their environment and the effect of pollution on them. The work involves development of ecologically sound methods of seafood production. (Imagine the development of sea-farms which help alleviate hunger from the world!) st_fish.jpg (3949 bytes)
floor.jpg (2324 bytes) Geological and geophysical oceanography explores the geophysical nature and structure of the ocean floor and map submarine structures. It studies the nature of rocks and sediments and tries to understand the process that created the ocean basins.
Marine and ocean engineering designs equipment and systems to be used in making oceanographic measurements. It is also engaged in research along with the other- scientists involved in oceanography.

Research in oceanography may include various diverse issues such as actively spreading mid-ocean ridges, analysis of lava of underwater volcanoes, or, assessment of the feasibility of mineral and chemical extraction from the ocean basin. Development for environmental technology to remove toxic contaminants and other pollutants from the ocean water is another important area of research.

To be successful in oceanography, you should have an inquisitive mind and a love for adventure. It is an interdisciplinary science. So, you should have adequate knowledge of various subjects like chemistry, earth science, biology, physics, computer science, and mathematics. The best option would be a degree in ocean engineering (BTech/MTech) or BTech in ocean engineering & naval architecture.

It is not possible in India to study BSc in oceanography; instead, you can get a Bachelors degree in physical science, biological, geology or civil/construction engineering and then specialize in oceanography at the postgraduate or doctoral level.

Alternatively, after your BSc/ BE, you can do MSc / ME / MTech in marine biology, marine biotechnology, marine geology, marine science, marine zoology, botany, marine geophysics, applied geophysics, ocean engineering, marine technology or geotechnology to work in the field of oceanography. It would be even better if you have a PhD in oceanography.

You may wonder about the employment opportunities in this area! Well, globally, employment opportunities are increasing at a modest rate of five to six per cent per annum. A high premium is being put on using oceanic studies in forecasting climatic, conditions, making oceans polluted free to maintain ecological balance. Developing systems for using marine life, as major source of food is also becoming very important. In India, apart from some work on the above fields, oceanographers are increasingly finding opportunities in petroleum exploration and extraction from sea basins. If you want to have a high profile career in oceanography, you may have to look for opportunities in USA after a Ph.D. from a US university.

With a degree in one of the many branches of ocean sciences you can look for a job in the department of clean development, Government of India, concerned with the ocean environment, marine resources, and the ocean’s strategic importance for national defence. Geological Survey of India and research institutions like National Institute of oceanography, have limited posts of research fellows and lectures.

Careers in private industries are also available, primarily in petrochemical and petroleum engineering in companies like ONGC (Oil & Nature Gas Commission), Essar Oil, Reliance Industries Ltd.

In governments departments and agencies, the starting salary after your MSc can be in the range or Rs 6,500 to Rs 8,000 per month depending on the nature of the job. In the private sector, the salary can be slightly higher. The same is true for research institutions. After for research institutions after your Ph.D., you can begin with about Rs 10,000 to Rs 12,000 per month.

Oceanography, apart from ocean engineering, is mainly research oriented. The change of doing manual work is extremely rare. Even if you get into a private sector petroleum company, it is unlikely that you will ever have to work out of your lab unless you are an ocean engineer. Outdoor work may involve sea diving (wow!), spending day abroad a ship in the middle of the ocean. So, those who are afraid of the sea should not think about it (and of course, those who get seasick, should stay far from it?). diving.jpg (4629 bytes)
Memo So, pal! Go ahead and find out the mysteries of the ocean for yourself. While you are at it, see if you can find a pearl or two for me, will ya?
