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 ...
Toxic effects of domestic sewage on zooplankton
(National Institute of Oceanography, Goa, 1987)
The toxic effects of raw domestic sewage on different groups of zooplank-ton, was tested in the laboratory for evaluating acute toxicity. 24 hr., LC-50 values for larvae of stomatopods, gastropods and chaetognaths (2-7% ...
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 ...
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 ...
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.) ...
Phytoplankton distribution in Cochin backwaters - a seasonal study
(National Institute of Oceanography, Goa, 1986)
Skeletonema costatum was the most abundant species in alt the 3 stations. The distribution of Asterionella japonica was least consistent than that of Nitzs-chia closterium which was most consistent at Station 1. At station ...
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 - ...
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 ...
