Estimation of air-sea CO2 flux in the coastal waters of Visakhapatnam
Latha, T.P.; Rao, K.H.; Sarma, V.V.S.S.; Seetaram, P.; Choudhury, S.B.; Nagamani, P.V.; Dutt, B.S.; Dhadwal, V.K.; Manna, S. (Springer, 2015)Observations were conducted in a time series mode off Visakhapatnam in Bay of Bengal, for a period of 10 days from 8 to 19th February 2013 to examine the short-term atmospheric events on chemical processes in the upper 100 ... -
Heat content of the Arabian Sea Mini Warm Pool is increasing
Nagamani, P.V.; Ali, M.M.; Goni, G.J.; Udaya Bhaskar, T.V.S.; McCreary, J.P.; Weller, R.A.; Rajeevan, M.; Gopalakrishna, V.V.; Pezzullo, J.C. (John Wiley & Sons, Ltd, 2016)Sea surface temperature in the Arabian Sea Mini Warm Pool has been suggested to be one of the factors that affects the Indian summer monsoon. In this paper, we analyze the annual ocean heat content (OHC) of this region ... -
Particle backscattering variability in the coastal waters of Bay of Bengal: A case study along off Kakinada and Yanam Regions
Latha, P.T.; Nagamani, P.V.; Rao, B.S.; Amarendra, P.; Rao, K.H.; Choudhury, S.B.; Dash, S.K.; Sarma, V.V.S.S. (IEEE, 2013)The distribution and variability of particulate back scattering coefficient (b<sub>bp</sub>) in the Godavari basin are reported for the first time using in situ measurements. A coastal cruise was conducted in the coastal ... -
Retrieval and Validation of Chlorophyll-a Concentrations in the Coastal Waters Off Yanam and Kakinada (Godavari) Basin Along East Coast of India.
Latha, T.P.; Nagamani, P.V.; Rao, K.H.; Dash, S.K.; Choudhury, S.B.; Rehman, A.; Sarma, V.V.S.S.; Babu, M.N.; Amarendra, P.; Rao, B.S.; Prasad, T.D.V. (Springer, 2014)In this study chlorophyll measurements were made during March 2012 in the estuarine waters of Off Kakinada and Yanam coast, Bay of Bengal onboard a coastal vessel. In-situ water samples and optical data was collected at ... -
Satellite and In Situ Observations of a Phytoplankton Bloom from Coastal Bay of Bengal: Role in pCO2 Modulation
Roy, R.; Rao, K.H.; Latha, T.P.; Dadhwal, V.K.; Sarma, V.V.S.S.; Nagamani, P.V.; Choudhury, S.B.; Pondala, S. (Springer, 2017)A phytoplankton bloom was monitored in coastal waters of Bay of Bengal and its influence in water column properties was investigated. Significant draw down of CO2 was noted within the vicinity of the bloom associated with ... -
Setting of cloud albedo in the atmospheric correction procedure to generate the ocean colour data products from OCM-2
Nagamani, P.V.; Latha, T.P.; Rao, K.H.; Suresh, T.; Choudhury, S.B.; Dutt, C.B.S.; Dadhwal, V.K. (Springer, 2015)Cloud masking is one of the primary and important steps in the atmospheric correction procedure in particular to coastal ocean waters. Cloud masking for ocean colour data processing is based on the assumption that the water ... -
Validation of satellite-derived tropical cyclone heat potential with in situ observations in the North Indian Ocean
Nagamani, P.V.; Ali, M.M.; Goni, G.J.; Dinezio, P.N.; Pezzullo, J.C.; UdayaBhaskar, T.V.S.; Gopalakrishna, V.V.; Nisha, K. (Taylor & Francis, 2012)Tropical cyclone heat potential (TCHP) is an important ocean parameter influencing cyclones and hurricanes. The best approach for computing TCHP is to use in situ measurements. However, since in situ data have both spatial ...
