The study area was selected based on its variability in current pattern with the change of season, topography and anthropogenic activity. Sangumal situated in Rameswaram island is located in Palk Bay (9°17' N lat; 79°19' E long). As it is near the temple of Rameswaram, it attracts
a lot of tourists round the year. There is a sewage outlet adjacent to this site which brings in effluent from the habitation in the island. The seagrass beds located here are exposed during the lowest low tide in the southwest monsoon season up to a distance of 1-2 km from the shore,
while during northeast monsoon season the current is in the reverse direction towards the coast from Bay of Bengal, hence there will be no exposure of seagrass beds even during low tide
