Physical characteristics of the coastal waters between Navapur and Umbharat, West coast of India. Part 2. Vertical homogeneity of temperature and salinity
(Indian Association for Limnology and Oceanography, 1982)Vertical distribution of temperature and salinity at five stations in the coastal waters off Navapur-Umbharat (Maharashtra-Gujarat coast, India) was studied over different seasons during 1978. The results showed that inspite ... -
Wave Persistence in Central Bay of Bengal during the Southwest Monsoon
(Indian Association for Limnology and Oceanography, 1982)Wave data collected on board RV @iGaveshani@@ in central Bay of Bengal during Monex-79 are analysed for significant wave height (H@ds@@), average period (T@dc@@), zero-crossing period (T@dz@@) and spectral width parameter ... -
Application of Remote Sensing Techniques to study the Distribution of Mangroves along the Estuaries of Goa
(International Scientific Publications, 1982)Aerial photographs were used to study the distribution of mangroves in the estuaries of Goa during 1978-79. The total area covered by 7 estuaries in Goa including the major Mandovi - Zuari estuarine complex, is approximately ... -
Physical characteristics of the coastal waters between Navapur and Umbharat, West coast of India. Part 3. Stability and dispersion
(Indian Association for Limnology and Oceanography, 1982)Vertical profiles of currents of the coastal waters between Navapur and Umbharat were analysed. Dynamic stability as well as the diffusion capacity of the water columns were estimated from the vertical distribution of ... -
Plastic pellets on the Caranzalem beach sands, Goa, India
(Indian Association for Limnology and Oceanography, 1982)Postmonsoonal survey of Caranzalem beach, Goa, India indicated the presence of plastic pellets. These pellets varied in shape, size and number, and are considered to be contaminants of marine environment -
Oceanography of the northern Arabian Sea
(Elsevier, 1982)The euphotic zone of the northern Arabian Sea ranges from 20-60 m with an average depth of about 40 m. Surface temperatures range from 22.5 to 28.5 degrees C, increasing from north to south. At 1000 m, the temperature is ... -
Carbohydrates in the waters of ponds of Ramanthuruthu Island, Cochin
(CSIR-NISCAIR, 1982)Particulate and dissolved carbohydrates in 4 ponds of the Ramanthuruthu Island (9 degrees 58.5'N lat. and 76 degrees 15.4'E long.) were studied for 1 yr (1978-79). Particulate carbohydrate concentration varied from 0.2 to ... -
Exploration and exploitation of marine living resources. A profile and projections upto the year 2000

Studies on the growth of penaeid prawns: 1. Length-weight relation and condition factor under different levels of feeding
(Indian Association for Limnology and Oceanography, 1982)Length-weight relation and earthworm feeding conditions under different levels for @iPenaeus indicus@@ and @iMetapenaeus dobsoni@@ were estimated. Length-weight exponent in both species was unaffected by the feeding levels ... -
Sub-littoral Meiobenthos of the Northeastern Bay of Bengal
(CSIR-NISCAIR, 1982)Of the 11 taxonomic groups represented, Nematoda followed by foraminifera and harpacticoida were dominant Meiofaunal abundance was more related to the texture of the sediment than variation in depth Population density ... -
Dissolved and particulate trace metals in the western Bay of Bengal
(CSIR-NISCAIR, 1982)Concentrations of Cu, Zn, Mn, Fe, Co, Ni and Pb, both in soluble and particulate forms were studied in the upper 200 m depth. Correlation between the trace metal concentration and the primary productivity was also investigated. ... -
Abyssal benthos of the Central Indian Ocean
(Elsevier, 1982)Quantitative studies of the abyssal benthos (3600 to 5300 m) of the central Indian Ocean show a rich fauna and high standing crops. Density of 3 meiofaunal and 12 macrofaunal taxa are large (2175 to 15233; chi = 6441 m-2). ... -
On the possibility of high-velocity tidal sterams as dynamic barriers to longshore sediment transport: evidence from the continental shelf off the Gulf of Kutch, India
(Elsevier, 1982)Differences in the bathymetry, bottom topography and the abundance of mica and clay minerals on the continental shelf north and south of the Gulf of Kutch, a macrotidal bay, indicate the presence of two distinct sedimentary ... -
Larval and Postlarval Stages of Sicyonia H. M. Edwards (Decapoda, Penaeidea: Sicyoniidae)
(Indian Association for Limnology and Oceanography, 1982)A third protozoeal stage and a late postlarval stage of a species belonging to the genus @iSicyonia@@ are described here with illustrations. The protozoea of @iSicyonia@@ can be easily distinguished by the presence of the ... -
Key to the identification of larvae and postlarvae of the penaeid prawns (Decapoda: Penaeidea) of the Indian Ocean
(Indian Association for Limnology and Oceanography, 1982)Some of the major criteria for identifying the larvae and early postlarvae of the penaeid prawns of the Indian Ocean are presented based on the study on material collected during the International Indian Ocean Expedition ... -
Bacteriological studies off Mangalore coast
(Indian Association for Limnology and Oceanography, 1982)Bacteriological studies of sediment and water in the near shore region off Mangalore showed that both limnotolerant and halotolerant bacteria were present. Significant inter-correlation (quantitative and qualitative) could ... -
Chlorophyll a, Phaeopigments and particulate Organic Carbon in the Northern and Western Bay of Bengal
(CSIR-NISCAIR, 1982)Distribution of chl a at surface closely corresponds to the surface flow patterns. Integral mean concentration (IMC) of chl a in inshore waters (depth 200 m) is double than that in the offshore waters (depth 200 m) while ... -
Denitrification in the Arabian Sea
(Elsevier, 1982)Estimates of the amount of denitrification in the Arabian Sea are inconsistent, and so two methods of calculations of 'original' nitrate concentrations used in earlier studies have been reviewed. Nitrite at intermediate ... -
On the distribution of fluoride, calcium and magnesium in the waters off the central west coast of India
(Indian Association for Limnology and Oceanography, 1982)The distribution of fluoride, calcium and magnesium was studied in the waters off the central west coast of India. The averages F/Cl, Ca/Cl and Mg/Cl ratios observed are (6.83 plus or minus 0.023) x 10@u-5@@, (0.02194 plus ...
