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.) ... -
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% ... -
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 - ... -
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 ... -
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 ... -
Seasonal changes in suspended sediment load in the Gauthami-Godavari Estuary
(Indian Association for Limnology and Oceanography, 1994)Studies carried out on suspended matter characteristics of the the Gautami Godavari Estuary revealed that the concentration of suspended matter (CSM) during southwest monsoon influenced mainly by the increased run off at ... -
Variation in biofouling on different species of Indian timbers
(Indian Association for Limnology and Oceanography, 1993)Biofouling on twenty species of wood exposed in waters of Mormugao Harbour, Goa, India have been presented. Macrofouling biomass varied from species to species. Maximum biomass was recorded on Artocarpus chaplasha (4 kg/m2) ... -
Seasonal primary production in different sectors of the EEZ of India
(Indian Association for Limnology and Oceanography, 1993)The seasonal and regional variations in the primary production, based on the data collected at 562 stations over the period from 1962 to 1988, are presented. The entire Indian Exclusive Economic Zone (EEZ), measuring 2.01 ... -
Observed currents at Bombay High during a winter
(Indian Association for Limnology and Oceanography, 1993)Ten day records of Aanderaa current meters (24 Dec 1981 to 2 Jan. 1982) at four depths, viz. 30, 45, 60 and 75 m at Bombay High (19˚24.5'N, 71˚2.5'E) off the west coast of India, in a water depth of 80 m have been subjected ... -

Modeling the barrier-layer formation in the South-Eastern Arabian Sea
(American Meteorological Society, 2007)The effect of salinity on the formation of the barrier layer (BL) in the South-Eastern Arabian Sea (SEAS) is investigated using an ocean general circulation model. In accordance with previous studies, the runoff distribution ... -
Simulated seasonal and interannual variability of mixed layer heat budget in the northern Indian Ocean
(American Meteorological Society, 2007)A global Ocean General Circulation Model (OGCM) is used to investigate the mixed layer heat budget of the Northern Indian Ocean (NIO). The model is validated against observations and shows a fairly good agreement with mixed ... -
