Seasonal patterns of phytoplankton biomass and productivity in a tropical estuarine complex (west coast of India)
(Indian Academy of Sciences, Bangalore, 1989)
Phytoplankton cell numbers and chlorophyll a determinations were made during the premonsoon, monsoon and postmonsoon periods in the Mandovi-Zuari estuarine complex (west coast of India). Primary productivity estimates ...
Extracellular products of photosynthesis in a tropical environment
(Indian Academy of Sciences, Bangalore, 1987)
Extracellular products in the Arabian Sea averaged 0.42 g/cm2/day and represented 35% of the total carbon fixed by phytoplankton. No seasonal changes are observed during the two seasons i.e. premonsoon (Jan-Feb) and onset ...
Nitrogenous nutrients and primary production in a tropical oceanic environment
(Rosenstiel School of Marine and Atmospheric Science of the University of Miami, 1986)
Measurements of the concentrations of nitrogenous nutrients and primary production were made at 10 stations along 8 degrees N and 10 degrees N in the tropical oceanic Lakshadweep waters Inorganic nitrogen (NO3, NO2 and ...
Effect of environment on pigment ratios in Dunaliella spp. from the salt pans of Gujarat
(Indian Academy of Sciences, Bangalore, 1989)
The effect of varying salinity and pH of the medium on growth and pigment ratios of Dunaliella cells in culture was studied. Cell growth was found to be optimal at pH 8 and at intermediate salt concentrations of 1-2 M NaCl. ...
Particulate organic matter in the coastal and estuarine waters of Goa and its relationship with phytoplankton production
(Elsevier, 1985)
In the coastal and estuarine waters of Goa, particulate organic carbon (POC) varied from 0.52 to 2.51 mg l-1 and from 0.28 to 5.24 mg l-1 and particulate phosphorus (PP) varied from 0.71 to 5.18 mu g l-1 and from 0.78 to ...
Urea as nitrogen source for phytoplankton production in coastal waters of Goa
(CSIR-NISCAIR, 1985)
Annual variation of urea in coastal waters off Goa, India is 0 to 2.92 mu g-at N.1/1 and 0 to 4.69 mu g-at N.1/1 in adjacent estuarine waters of Mandovi. Peaks of phytoplankton production accompanied with the decrease in ...
Dissolved organic nutrients and phytoplankton production in the Mandovi estuary and coastal waters of Goa
(Indian Association for Limnology and Oceanography, 1984)
Total organic nitrogen (TON) and dissolved organic phosphorus (DOP) in the coastal and estuarine waters of Goa, India varied from 0.6 to 47.1 mu g-at N 1-1 and 0.12 to 3.49 mu g-at P l-1 respectively. The chlorophyll content ...
Primary production in the Bay of Bengal during August 1977
(Indian Association for Limnology and Oceanography, 1983)
Primary production, chlorophyll @ia@@, phaeophytin, phytoplankton and particulate organic carbon (POC) were studied at 14 stations in the Bay of Bengal during August 1977. Column primary production, chlorophyll @ia@@, and ...
Oceanography of the northern Arabian Sea
(Elsevier, 1982)
The euphotic zone of the northern Arabian Sea ranges from 20-60 m with an average depth of about 40 m. Surface temperatures range from 22.5 to 28.5 degrees C, increasing from north to south. At 1000 m, the temperature is ...
Adaptations in Phytoplankton to Changing Conditions in Tropical Estuaries
(Indian Association for Limnology and Oceanography, 1980)
Experimental studies on phytoplankton organisms from Cochin backwaters (a tropical estuary) have shown that many algal forms are adapted to changing conditions of salinity, light and nutrients. Photosynthesis in 12 species ...
