Air-sea gas transfer in a shallow, flowing and coastal environment estimated by dissolved inorganic carbon and dissolved oxygen analyses
Abe, O.; Watanabe, A.; Sarma, V.V.S.S.; Matsu, Y.; Yamano, H.; Yoshida, N.; Saino, T. (The Oceanographic Society of Japan, 2010)We estimated gas exchange rates in Kabira Reef at Ishigaki Island, southwest Japan, using a mass balance calculation with dual ‘biological’ tracers: dissolved inorganic carbon (DIC) and dissolved oxygen (DO). The nighttime ... -
Coastal versus open-ocean denitrification in the Arabian Sea
Naqvi, S.W.A.; Naik, H.; Pratihary, A.K.; DeSouza, W.; Narvekar, P.V.; Jayakumar, D.A.; Devol, A.H.; Yoshinari, T.; Saino, T. (The European Geosciences Union, 2006)The Arabian Sea contains one of the three major open-ocean denitrification zones in the world. In addition, pelagic denitrification also occurs over the inner and mid-shelf off the west coast of India. The major differences ... -
Diurnal variability of Synechococcus abundance in Sagami Bay, Japan
Mitbavkar, S.; Saino, T. (Springer, 2015)Synechococcus, the most dominant picophytoplankton in coastal regions, exhibits diurnal variations in the open ocean. The aim of this study was to assess its short-term population dynamics and cell cycle phases through DNA ... -
Effect of biofilm on fluorescence measurements derived from fast repetition rate fluorometers
Patil, J.S.; Saino, T. (Taylor and Francis, 2015)This study evaluates, for the first time, the influence of biofilms on single and double optical window (SOW and DOW, respectively) fast repetition rate fluorometer (FRRF) measurements of microalgal photosystem-II initial ... -
Estimating of gas transfer velocity using triple isotopes of dissolved oxygen.
Sarma, V.V.S.S.; Abe, O.; Honda, M.; Saino, T. (Springer, 2010)The atmosphere-ocean exchange of climatically important gases is determined by the transfer velocity (k) and concentration gradient across the interface. Based on observations in the northwestern subarctic Pacific and ... -
Fluctuations in productivity and denitrification in the southeastern Arabian Sea during the Late Quaternary
Kessarkar, P.M.; Rao, V.P.; Naqvi, S.W.A.; Chivas, A.R.; Saino, T. (Current Science Association, 2010)Sedimentological and stable isotopic characteristics of sediments have been studied in a core from the southeastern Arabian Sea containing records of the past 70 ka. Palaeoproductivity proxies such as organic carbon (C ... -
Impact of sinking carbon flux on accumulation of deep-ocean carbon in the Northern Indian Ocean
Sarma, V.V.S.S.; DileepKumar, M.; Saino, T. (Springer, 2007)The export of carbon through the biological pump from the surface to the deep ocean has a direct influence on the removal of CO sub(2) from the atmosphere. This is because the carbon is sequestered for only a few days to ... -
Influence of physical processes and freshwater discharge on the seasonality of phytoplankton regime in the Bay of Bengal
Gomes, H.; Goes, J.I.; Saino, T. (Pergamon, 2000)The seasonality of phytoplankton was examined in the western and northern Bay of Bengal using shipboard data collected during three seasons as well as ocean colour imagery from OCTS and Sea WiFS. Seasonal changes in the ... -
Role of environment and hydrography in determining the picoplankton community structure of Sagami Bay, Japan
Mitbavkar, S.; Saino, T.; Horimoto, N.; Kanda, J.; Ishimaru, T. (The Oceanographic Society of Japan, 2009)Seasonal variations in the picoplankton community were investigated from June 2002 to March 2004 within the photic zone of Sagami Bay, Japan. The study area was mostly dominated by coastal waters during the warm period ... -
Spatial variations in time-integrated plankton metabolic rates in Sagami Bay using triple oxygen isotopes and O2:Ar ratios
Sarma, V.V.S.S.; Abe, O.; Saino, T. (American Society of Limnology and Oceanography, 2008)Plankton metabolic rates, such as rates of gross, net community production and community respiration, were measured in the surface waters using triple oxygen isotopes and O2 : Ar ratios. The 17 delta anomaly showed clear ...
