PROFESSIONAL EXPERIENCE

ORGANIZATION Shipping Corporation of India, Mumbai [May 2010]

PROJECT • Worked in the Ship Building & Services Dept. on the ship acquisition process

• Reviewed the stability calculation, vibration analysis & GA drawings for the acquisition of a 57,000 ton DWT bulk carrier

• As part of a team, analyzed and recommended changes to the ship design; sent for approval

SUMMER INTERNSHIP

ORGANIZATION MIT, Woods Hole Oceanographic Institute of Technology Massachusetts, USA [May-July 2009]

PROJECT TITLE Dispersion Relationship of the Kelvin waves in the Indian and the Pacific Ocean

PROJECT BREIF • Fourier analyzed Sea Surface Height data of these oceans, acquired through Satellite Altimetry, to compute the power spectral density, to find out the contribution of the different frequencies.

• The analysis showed that the waves run parallel to each other with almost the same velocity and the higher power levels are at low frequencies, and that the waves move eastward.

• Having concluded that these are Kelvin waves, the dispersion relation was used to establish that the waves are more visible in the Pacific Ocean, a fact attributed to the superposition of waves in the Indian Ocean due to the presence of many islands and smaller size.

ACHIEVEMENTS • Developed a method to identify Kelvin waves on the ocean surfaces

• Concluded the presence of Kelvin waves is much less in the Indian Ocean than the Pacific Ocean

• Received a verbal Invitation for a graduate internship with the Dept. of Physical Oceanography
