  abstract = {{W}e present a methodology to derive surface geostrophic current from a newly released altimetric sea-level data set. {TOPEX}/{P}oseidon data were first completely reprocessed from {G}eophysical {D}ata {R}ecords using new algorithms accommodating marginal seas and coastal conditions. {T}he methodology applied to the reprocessed data essentially consists of a smoothing of the raw along-track coastal altimetric data at scales at which the geostrophic equilibrium holds. {T}his was reduced to a computational procedure using a set of objective criteria. {W}e have applied the method to the {E}ast {I}ndia {C}oastal {C}urrent ({EICC}) at the western boundary of the {B}ay of {B}engal. {T}his paper first examines the quality of the new data set, which compares well with tide-gauge data; the current we derived is consistent with independent estimates. {O}ur methodology reveals the full spectrum of the along-shore current, ranging from intra-seasonal to inter-annual time scales, from the deep ocean to the shelf-break area where the {EICC} exists. {T}he algorithm can be applied to any coastal region where an order of the {R}ossby radius can be defined, and it therefore opens up bright prospects for mapping the variability of other boundary-current systems in the world ocean from altimetry.},
