Effect of carbon source concentration and culture duration on retreivability of bacteria from certain estuarine, coastal and offshore areas around the peninsular India.
(Indian Academy of Sciences, 2006)Improved culture-based approaches efficiently compliment the limitations encountered in molecular methods to delineate the diversity and functions of uncultured organisms. The present study endeavours to reduce the anomaly ... -
Mining of phosphorite resources from the Indian continental shelf will help food production
(Books & Journals Private Ltd., 1983)Phosphate is used as a plant nutrient in fertilisers The main sources of phosphate are phosphatic rocks The National Institute of Oceanography had conducted a phosphate exploration programme on the continental shelf of ... -
Observations on phytoplankton pigments, zooplankton and physico-chemical parameters in surface waters from southern Indian Ocean and Antarctic region
(Indian Association for Limnology and Oceanography, 1993)Observations on distribution of chlorophyll a, phaeopigments, zooplankton and physico-chemical parameters in the Southern Ocean were carried out during 9th Indian Antarctic-Expedition (1989-1990). The results indicated ... -
Bioactivity of marine organisms. Part 3. Screening of marine algae of Indian coast for biological activity
(Indian Association for Limnology and Oceanography, 1991)Ethanolic extracts from Indian marine algae have been tested for anti-viral, anti-bacterial, anti-fungal, anti-fertility, hypoglycaemic and a wide range of pharmacological activities. Of 34 species investigated 17 appeared ... -
Solar desalination, brine and fine chemicals - a preliminary report
(Indian Association for Limnology and Oceanography, 1991)Solar stills put into operation by taking known quantities of sea water of different salinities varying from 27. 75 - 36.27 x 103 during April-May 1990, indicated fresh water yield of 55-68% (av. 64) The volumes of brine ... -
Harmonic tidal analysis at a few stations using the least squares method
(Indian Association for Limnology and Oceanography, 1991)Using the least squares method, harmonic analysis has been performed on hourly water level records of 29 days at several stations depicting different types of non-tidal noise. For a tidal record at Mormugao, which was free ... -
Mixing in Visakhapatnam harbour and nutrient inputs to nearshore waters, east coast of India
(Indian Association for Limnology and Oceanography, 1990)The flushing time (t) and replacement time CD are computed for different seasons to understand mixing in Visakhapatnam harbour. Replacement times are higher than the flushing times indicating that the transverse mixing in ... -
Spectra of currents and temperature off Godavari (east coast of India)
(National Institute of Oceanography, Goa, 1989)Time series data of currents and temperature obtained from a mooring of current meters off Godavari (East Coast of India) during September 1980 are analysed to study the space scales of semidiurnal and internal oscillations ... -
Hydrography of the northern Bay of Bengal during southwest monsoon
(National Institute of Oceanography, Goa, 1989)Hydrography of the Bay of Bengal to the north of 19°N during southwest monsoon is discussed on the basis of temperature, salinity, oxygen and density distribution. The thermohaline features are analysed to understand the ... -
Chemistry of the sea surface microlayer. 1. Fabrication and testing of the sampler
(National Institute of Oceanography, Goa, 1988)A screen sampler fabricated to study the sea surface microlayer (SML) has been described. The screen sampler was tested in the Mandovi estuary and adjacent waters. Physico-chemical parameters of the subsurface waters from ... -
Seabed topography and distribution of manganese nodules in the Central Indian Ocean
(National Institute of Oceanography, Goa, 1988)The relationship between seabed topography and distribution of nodules, recovery of free fall grab samplers, nodule size and chemical composition of manganese nodules in the Central Indian Ocean have been studied. Nodule ... -
Phytoplankton and zooplankton of some paddy-cum-prawn culture fields in and around Cochin
(National Institute of Oceanography, Goa, 1988)The Phytoplankton and zooplankton from the paddy-cum-prawn culture fields from 4 areas in and around the Cochin backwaters were studied. Total Phytoplankton counts in the seasonal and perennial fields in all the areas ... -
Application of FFT methods to wind wave data series by adding zeros
(National Institute of Oceanography, Goa, 1987)A method to add zeros (in FFT methods) to a short data sample (< 2m) to make the sample size equal to 2m is illustrated in this paper. It is found that the spectrum could be computed reliably without any undesirable side ... -
Effect of attenuation correction on surface amplitude distribution of wind waves
(National Institute of Oceanography, Goa, 1987)Some selected wave profiles recorded using a ship borne wave recorder are analysed to study the effect of attenuation correction on the distribution of the surface amplitudes. A new spectral width parameter is defined to ... -
Petroleum hydrocarbons in surface sediments in Kandla creek (Gujarat)
(National Institute of Oceanography, Goa, 1987)Petroleum hydrocarbons in the surface sediments were determined gravimetrically and spectroscopically to evaluate petroleum oil pollution in the Kandla creek. They ranged from 9.6 — 140.5 and 6.5 — 23.3 μg g-1 (wet wt.) ...
