I am trying to understand the energetics of coastal circulations on the west coast of India. what are the type of analysis and modelling study required?. what are the reliable temperature/salinity sources can be used as boundary conditions?.
Mohammed: this is an extremely broad set of questions.
(1) What analyses are required....
Depends on what the question is of course. If it is the seasonal cycle of the circulation then you may find that the global HYCOM simulations/analyses are useful. You need to understand THREDDS and NETCDF to acces them from http://tds.hycom.org/thredds/GLBu0.08/expt_19.1.html?dataset=GLBu0.08/expt_19.1/2012/3hrly.
(2) What TS data is available?
NOAA has a good service at http://www.nodc.noaa.gov/OC5/WOD/pr_wod.html.
Best of luck.

For the surveys depends on the spatial scale of your study...what do you want study?
On top of tides, winds and density, if you are referring to near-shore circulation, the effect of gravity waves through Stokes drift velocities and wave setup (water piling against the coast) can be very important... but it depends on the spatial scale, as Francesco said, and the particular characteristics of the area you are focusing on.
This is a broad research theme. I would recommend the paper by Uchiyama et al (2010) for the wave currents interaction in the near-shore.
