Narvekar, J.; Chowdhury, R.R.; Gaonkar, D.; DineshKumar, P.K.; PrasannaKumar, S. (Springer-Nature, 2021)Upwelling is a physical phenomenon that occurs globally along the eastern boundary of the ocean and supports pelagic fishery which is an important source of protein for the coastal population. Though upwelling and associated ... -
Observed coherency in the seasonal sea level fluctuations along the coastline of the Indian subcontinent
Srinivas, K.; DineshKumar, P.K.; Ravichandran, C. (School of Naval Oceanology and Meteorology, 2007)Seasonal sea level fluctuations result from oceanographic, meteorological and hydrological forcings. The largest seasonal signals of sea level, however, are primarily caused by hydrological forcings. The climatological ... -
