Improved bathymetric datasets for the shallow water regions in the Indian Ocean
Sindhu, B.; Suresh, I.; Unnikrishnan, A.S.; Bhatkar, N.V.; Neetu, S.; Michael, G.S. (Indian Academy of Sciences, 2007)Ocean modellers use bathymetric datasets like ETOPO5 and ETOPO2 to represent the ocean bottom topography. The former dataset is based on digitization of depth contours greater than 200 m, and the latter is based on satellite ... -
Improving modeling of tides on the continental shelf off the west coast of India
Testut, L.; Unnikrishnan, A.S. (Coastal Education and Research Foundation, 2016)Global tidal solutions are sometimes inaccurate in coastal regions. This is particularly true in some regions of the northern Indian Ocean, which are characterized by wide continental shelves and large tidal ranges. We ... -
Increasing trend of `Break-Monsoon` conditions over India — Role of ocean–atmosphere processes in the Indian Ocean
RameshKumar, M.R.; Krishnan, R.; Sankar, S.; Unnikrishnan, A.S.; Pai, D.S. (IEEE, 2009)Analysis of daily rainfall data over India during the period 1951–2007 reveal an increased propensity in the occurrence of `monsoon-breaks` over the subcontinent. The increasing trend is seen both in the duration and ... -
Indian Moorings: Deep-sea current meter moorings in the Eastern Equatorial Indian Ocean

Influence of ENSO on the Pacific decadal oscillation in CMIP models
Nidheesh, A.G.; Lengaigne, M.; Vialard, J.; Izumo, T.; Unnikrishnan, A.S.; Cassou, C. (Springer, 2017)Emerging decadal climate predictions call for an assessment of decadal climate variability in the Coupled Model Intercomparison Project (CMIP) database. In this paper, we evaluate the influence of El Ni�o Southern Oscillation ... -
Is sea-level rising?
Unnikrishnan, A.S. (Ocean Society of India, 2016)There has been considerable research on sea-level-rise caused by global warming. The various reports of the Intergovernmental Panel on Climate Change (IPCC) made assessments of observed sea level rise and future projections. ... -
Large-scale processes in the upper layers of the Indian Ocean inferred from temperature climatology
