A checklist of benthic foraminiferids from the inner shelf of Dabhol-Vengurla region, Arabian Sea
(Geological Society of India, 1979)Sixty-four benthonic foraminiferids are reported from Dabhol-Vengurla innershore neritic environment and they are listed in the order of their relative abundance. Small microenvironments or milieus created by the dominance ... -
A comparison of the marine and estuarine benthic fauna of the nearshore regions of the Arabian Sea.
(National Academy of Sciences, India, 1968)The distribution and abundance of the benthic fauna of the Arabian sea were studied in the nearshore region at a depth of 10 fathoms, about 7 miles off Cochin. The results showed that the macrofauna was more abundant than ... -
A preliminary report on the distribution and relative abundance of Euthecosomata with a note on the seasonal variation of Limacina species in the Indian Ocean
(National Academy of Sciences, India, 1968)Euthecosomata (holoplanktonic opisthobranch molluscs) sorted out from the collections of the International Indian Ocean Expedition are now being studied and the present communication is a first report based on an examination ... -
A preliminary study of anaerobic thiosulfate-oxidising bacteria as denitrifiers in the Arabian Sea
(Taylor & Francis, 1988)Bacteria which oxidize thiosulfate and reduce nitrate (TONRB) and bacteria which oxidize thiosulfate and denitrify (TODB) sampled at 5-, 100-, 200-and 300-m depths were enumerated in agar shake cultures by colony counting ... -
A study of medusae from Andaman and Nicobar waters
(Zoological Society of Kerala, 1993)The results obtained from 14 cruises undertaken by FORV Sagar Sampada during the period 1986-1990 from Andaman and Nicobar waters are detailed. 346 zooplankton collections were made during this period and medusae were found ... -
Abundance and size variation of Globorotalia menardii in the Northeastern Indian Ocean during the Late Quaternary
(Geological Society of India, 2012)Variation in absolute abundance, size and coiling direction ratio of the planktic foraminifera Globorotalia menardii during the late Quaternary have been studied in three cores, collected along a north-south transect from ... -
Abundance of dissolved polysaccharides in the oxygen minimum layer of the northern Indian Ocean
(Elsevier, 1998)Water samples collected from the upper 1500 m at seven stations in the Bay of Bengal and at five stations in the Arabian Sea, were analysed for dissolved carbohydrate by the MBTH (3-methyl-2-benzothiazolenone hydrazone ... -
Abundance of macroalgal organic matter in biofilms: Evidence from n-alkane biomarkers
(Taylor and Francis, 2004)Biofilm development on titanium panels immersed in the surface waters of Dona Paula Bay, Goa, India was investigated using molecular biomarkers such as n-alkanes and other chemical and biological parameters. Biofilm biomass ... -
Adaptations in Phytoplankton to Changing Conditions in Tropical Estuaries
(Indian Association for Limnology and Oceanography, 1980)Experimental studies on phytoplankton organisms from Cochin backwaters (a tropical estuary) have shown that many algal forms are adapted to changing conditions of salinity, light and nutrients. Photosynthesis in 12 species ... -
An interactive program for digitization of seabed photographs
(CSIR-NISCAIR, 1989)A program for dignitization of seabed photographs to compute coverage and abundance of polymetallic nodules is developed. Since the objects in the seabed photograph are partially covered by thin sediment layer, the automatic ... -
An overview of the planktonic foraminiferal fauna in waters off the Kerala Coast, south-west India during summer
(Marine Biological Association of India, 1997)Twentyeight species of planktonic Foraminifera are recorded from 46 plankton samples collected from 27 stations of 5 traverses along the Kerala Coast. The mean abundance of total foraminiferal sepcimens of all the stations ... -
Assessment of viability in the bacterial standing stock of the Antarctic Sea from the Indian side
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 2001)During the austral summer, the bacterial population along the cruise track extending from 70 degrees S and 18 degrees E to 30 degrees S and 35 degrees E are examined. During the cruise, three distinct fractions of the ... -
Bacterial abundance and production in the central and eastern Arabian Sea
(Current Science Association, Bangalore, India, 1996)Seasonal and spatial variations in bacterial and picoplankton abundances and bacterial production (thymidine incorporation rates) were determined in the water column up to 150 m in several stations in the central and eastern ... -
Bacterial abundance, communities and heterotrophic activities in the coastal waters off Tamil Nadu
(NISCAIR, CSIR, 1996)Culturable aerobic heterotrophic bacterial (CAHB) numbers, total direct counts (TDC), bacterial generic composition and uptake of labelled glucose by natural microbial assemblages were studied from a few selected coastal ... -
Bacteriological quality of creeks and marine water bodies in North Goa: Ecosystem upkeep perspectives for tourism-related activities
(Tata Energy Research Institute, India, 2003)Keeping tourism-related activities in the fore, several relevant bacteriological parameters were studied in depth in North Goa's aquatic ecosystems. Total bacterial abundance and activity for sewage-indicator bacteria and ... -
Benthic communities associated with ferromanganese nodules from the Central Indian Ocean
(Regional Research laboratory, Bhubaneswar, 2005)Micro- meio- and macrobenthic associations with Ferromanganese nodules collected from the Central Indian Ocean were evaluated. The area of nodules ranged from 13.58 to 21 cm super (2). The density of abyssal macrobenthos ... -
Benthos
(Oxford and IBH, New Delhi, 2001)Benthic organisms are sessile and sedentary in nature. True benthos can be divided into two groups - epifauna and infauna. They comprise major invertebrate phyla. Benthic organisms are separated into micro, meio, macro and ... -
