Primary production of tropical marine ecosystems
(Wiley Eastern, New Delhi, 1992)
Among tropical marine ecosystems estuaries are one of the highly productive areas and act as a nursery to large number of organisms. The primary production in most of the estuaries is less during the monsoon period. ...
Assimilation potential of water column biota: Mesocosm-based evaluations
(Tata Energy Research Institute, India, 2003)
This chapter presents a generalized picture of various aspects of assimilation by native biota and underscores the importance of safeguarding the environment from excessive discharge of nutrient-rich effluents, even though ...
Natural isotopic composition of nitrogen in suspended particulate matter in the Bay of Bengal
(The European Geosciences Union, 2004)
The first measurements of nitrogen isotopic composition (delta sup(15) N) in suspended particulate matter (SPM) of the surface Bay of Bengal (BOB) at 24 different locations during pre- (April-May 2003) and post- ...
Influence of physical processes and freshwater discharge on the seasonality of phytoplankton regime in the Bay of Bengal
(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 ...
Phytoplankton production and chlorophyll distribution in the eastarn and central Arabian Sea in 1994-1995
(Current Science Association, Bangalore, India, 1996)
Measurements of primary production, chlorophyll a, particulate organic carbon (POC) and nitrogen (PON) were carried out during the inter-monsoon winter monsoon and summer monsoon seasons of 1994-95 in the central and eastern ...
Distribution of nutrients in the coastal and estuarine waters of Goa
(Indian Association for Limnology and Oceanography, 1987)
Concentrations of nitrate and phosphate in the coastal waters of Goa varied from 0 to 2.4 mu g at 1-1 and from 0.1 to 2.4 mu g at 1-1 respectively, during post and premonsoon periods. In the estuarine region the nutrients ...
Variation of physico-chemical characteristics with tide in Visakhapatnam harbour waters, east coast of India
(CSIR-NISCAIR, 1987)
Variations in physico-chemical parameters (DO, BOD, NO2, SiO4, PO4 suspended solids, salinity and currents) observed in the waters of main channel of Visakhapatnam Harbour over a tidal cycle in different seasons from ...
Nutrients in some estuaries of Kerala
(Indian Association for Limnology and Oceanography, 1983)
Some environmental parameters and nutrients like inorganic phosphate, nitrate, nitrite and ammonia from four estuaries namely Kallai, Beypore, Korapuzha and Mahe along north Kerala Coast were studied for an year (1980-81). ...
Seasonal changes in Carrageenan and other Biochemical Constituents of Hypnea Musciformis
(CSIR-NISCAIR, 1980)
Carrageenan content was maximum in winter. Near inverse relationship was observed between the total carbohydrate and carrageenan. Protein levels were highest when the nitrogenous nutrients were high
Effects of industrial waste disposal on the water quality of the river Kolak
(Indian Association for Limnology and Oceanography, 1980)
About 6 mld of industrial waste water is discharged without proper treatment in the fresh water zone of the river Kolak. Parameters like suspended solids, pH, chloride, DO, BOD, phosphate, nitrate, boron, sulphate and trace ...
