Sea surface temperature changes during May and August in the western Arabian Sea over the last 22 kyr: Implications as to shifting of the upwelling season
(Elsevier, 2011)In the western Arabian Sea (WAS), the highest seasonal sea surface temperature (SST) difference presently occurs between May and August. In order to gain an understanding on how monsoonal upwelling modulates the SST ... -
Re-introduction and supplementation of species of Acropora and Pocillopora into the lagoons of Lakshadweep Islands, India
(Abu Dhabi: IUCN/SSC Re-introduction Specialist Group, 2008)The genera Acropora and Pocillopora are represented by a large number of species in most coral reefs They are more sensitive to environmental changes and anthropogenic effects and hence are more at risk than other coral ... -
Distribution of diatom Pseudo-nitzschia and dinoflagellates of Dinophysis spp along coast off Goa
(Triveni Enterprises, 2011)As a part of an annual analysis on the phytoplankton distribution and composition, regular monthly sampling carried out during October 2007-September 2008 from salinity gradient zones in the intertidal waters along the ... -
Waves in the nearshore waters of northern Arabian Sea during the summer monsoon
(Elsevier, 2011)Waves at 15 m water depth in the northern Arabian Sea are measured during the summer monsoon for a period of 45 days and the characteristics are described. The significant wave height varied from 1.1 to 4.5 m with an average ... -
Calamenenes - aromatic bicyclic sesquiterpenes - from the Indian gorgonian Subergorgia reticulata (Ellis and Solander, 1786)
(Taylor & Francis, 2011)Three aromatic sesquiterpene derivatives, (+)-(7R, 10S)-2-methoxy calamenene (1), (+)-(7R, 10S)-2,5-dimethoxy calamenene (2) and (+)-(7R, 10S)-2-methoxy-5-acetoxy calamenene (3) were isolated from the methanol extract of ... -
Comparative efficacy of four anaesthetic agents in the yellow seahorse, Hippocampus kuda (Bleeker, 1852)
(Elsevier, 2011)In modern aquaculture, anaesthetics play an important role in reducing handling stress and mortality. In this investigation, the efficacy of four anaesthetic agents (MS-222, benzocaine, clove oil and 2-phenoxyethanol) was ... -
Sea surface salinity variability in the tropical Indian Ocean
(Elsevier, 2011)Argo profiles of temperature and salinity data from the north Indian Ocean have been used to address the seasonal and interannual variability of Sea Surface Salinity (SSS) and SSS Anomaly (SSSA) in 2 boxes from the eastern ... -
Nitrate levels modulate denitrification activity in tropical mangrove sediments (Goa, India)
(Springer, 2011)A study to examine the short-term effect of nitrate and organic carbon addition on denitrification activity was carried out on sediments from a mangrove ecosystem prone to anthropogenic activities (Divar, Goa, India). ... -
Neuro-fuzzy based approach for wave transmission prediction of horizontally interlaced multilayer moored floating pipe breakwater
(Elsevier, 2011)The ocean wave system in nature is very complicated and physical model studies on floating breakwaters are expensive and time consuming. Till now, there has not been available a simple mathematical model to predict the ... -
A novel hybrid technology for remediation of molasses-based raw effluents
(Elsevier, 2011)A novel three-step technology for treatment of four molasses-based raw industrial effluents, varying in their COD, color and turbidity is reported here. Sequential steps involved in this treatment are; (1) sonication of ... -
Surface microtextures of quartz grains from the central coast of Tamil Nadu
(Geological Society of India, 2011)Quartz grain surface micro textures of 12 samples collected from the beach were examined under scanning electron microscopy to understand the role of coastal processes on their transportation and deposition. The study area ... -

Tidal propagation off the central west coast of India
(NISCAIR, CSIR, 2011)Present study reviews the characteristics of tidal propagation on the continental shelf off the central west coast of India. Available observations from tide gauges are used to describe the variations of tidal ranges along ... -
Temporal variability of macrofauna from a disturbed habitat in Zuari estuary, west coast of India
(Springer, 2011)Natural disturbances along with human interference make the tropical estuaries amongst the most disturbed areas globally. In spite of this, information on the seasonal variability of macrofauna from tropical estuaries is ... -
An evaluation of flora from coastal sand dunes of India: Rationale for conservation and management
(Elsevier, 2011)A key component that guarantees stability of coastal sand dunes (CSDs) is vegetation. In this study, the floristic composition and distribution from CSDs of India is reviewed. Analysis revealed a total 338 species of CSD ... -
Physical processes in the Gulf of Kachchh: A review
(NISCAIR, CSIR, 2010)A brief review of various physical processes acting in the Gulf of Kachchh (GoK), which have prominent roles in Gulf dynamics, is presented in this article. The eddies present in the GoK confirm that they are permanent ... -
Distribution of meroplankton in relation to the thermocline in the Western Indian ocean during day and night
(Marine Biological Association of India, 1991)Based on 35 night and 27 day zooplankton collections made from a depth of 200 m to surface and the thermocline layer to surface, the distribution of meroplankton in relation to the thermocline was studied in the western ... -
Natural product antifoulants from the octocorals of Indian waters
(Elsevier, 2011)Natural Product Antifoulants (NPAs) have been proposed as one of the best alternatives for the globally banned toxic biocide -TBT-in antifouling coatings. In search of NPAs from Indian waters twenty nine species of Octocorals, ... -
