El Nino: The climate changer
(NISCAIR, CSIR, 1986)
EL Nino is an abnormal warm situation in the Pacific Ocean which manifests once in a few years due to ocean-atmosphere interaction. It is much talked about inrecent times because it is believed to be'associated with floods, ...
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 ...
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 ...
Biochemical studies in Ulva reticulata Forsskal
(National Institute of Oceanography, Goa, 1986)
Major metabolites like proteins, carbohydrates and lipids in the alga Ulva reticulata were estimated. Carbohydrate was found to decrease after December which may perhaps be due to the spore formation and extensive growth ...
Characterization of purple and green photosynthetic bacteria isolated from the lagoon of Agatti Atoll (Lakshadweep Sea)
(Indian Academy of Sciences, 1986)
The occurrence and characterisation of photosynthetic sulphur bacteria in the tropical waters is reported. These were found with decaying beds of seagrass at Agatti Island, Lakshadweep, India. These were cultured and ...
Relationship between chlorophyll-a and column primary production
(National Institute of Oceanography, Goa, 1986)
Relationship between surface chlorophyll a and column primary production has been established to help in estimating the latter more quickly and accurately. The equation derived is Primary Production, y = 0.54 Ln Chl a - ...
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 ...
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 ...
The intriguing relationship between coiling direction and reproductive mode in benthic foraminifera
(The Palaeontological Society of India, 1989)
Changes in coiling direction in foraminifera have been used extensively as proxy data for paleoclimates. However, most of the studies centred around planktonic foraminifera, and various causes (including reproductive mode) ...
Bioactivity of marine organisms. 4. Screening of some marine animals from the Indian coast
(Indian Association for Limnology and Oceanography, 1989)
Of twenty eight alcoholic extracts of marine organisms screened for a wide range of pharmacological activities, 15 showed biological activity. Of these two were anti implantation, 3 CNS stimulant, 2 hypotensive, 4 diuretic, ...
