Operational forecast of oil spill trajectory and assessment of impacts on intertidal macrobenthos in the Dahanu region, west coast of India
(Coastal Education and Reserch Foundation, 2013)A two-dimensional model has been developed and applied to the hypothetical spills of crude oil in the Dahanu area on the west coast of India. An attempt has also been made to quantify the intertidal macrobenthic biomass ... -

Operationally defined mercury (Hg) species can delineate Hg bioaccumulation in mangrove sediment systems: A case study
(2020)This study investigated the linkage between mercury (Hg) speciation in the surficial sediments from a mangrove ecosystem of the Zuari Estuary, west coast of India, with Hg bioaccumulation in gastropods collected from the ... -
Opisthorchis viverrini: Detection by polymerase chain reaction (PCR) in human stool samples
(Elsevier, 2008)A polymerase chain reaction (PCR) assay was evaluated for detection of Opisthorchis viverrini eggs in the stool specimens of light and heavily infected individuals in Khon Kaen province of Thailand. A total of 75 fecal ... -
Opportunities for offshore mineral exploration in the Indian Ocean
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)The Indian Ocean offers several opportunities for offshore mineral resources in the nearshore and coastal areas, the EEZs of different countries as well as the deep sea regions. The coastal and nearshore resources of heavy ... -

Optical characteristics of colored dissolved organic matter during blooms of Trichodesmium in the coastal waters off Goa
(Springer, 2020)Trichodesmium, a marine cyanobacterium, plays a significant role in the global nitrogen cycle due to its nitrogen fixing ability. Large patches of Trichodesmium blooms were observed in the coastal waters, off Goa during ... -
Optical closure of apparent optical properties in coastal waters off Goa
(Indian Society of Remote Sensing, 2015)Inherent and apparent optical properties were measured for coastal waters off Goa, a site on the west coast of India using the in-situ measuring profiling optical instruments. The optical closure was obtained using the ... -
Optical properties of marine waters and the development of bio-optical algorithms
(Indian Inst. of Technol., New Delhi and NIO, India, 1994)This paper presents the primary optical variables used in the measurement of the optical properties of marine waters. How can in-situ measurements be used in the optical recognition of coastal and open ocean waters. We ... -
Optimal estimation of ship's attitudes for beampattern corrections in a coaxial circular array
(Taylor and Francis, 1994)A study is conducted to estimate the accurate attitude of a ship's motion and the estimation is used to arrive at the corrections required for a farfield pattern of a coaxial circular array. The relevant analytical expression ... -
Optimal parametric modelling of measured short waves
(Allied, Chennai (India), 1996)The spectral analysis of measured short waves can efficiently be carried out by the fast Fourier transform technique. Even though many present techniques can be used for the simulation of time series waves, these may not ... -
Optimal Sensor placement for acoustic range-based underwater robotic positioning
(International Federation of Automatic Control, 2013)This paper addresses the problem of optimal sensor placement for acoustic range-based underwater target positioning. In particular, we focus on the experimental set-up whereby target positioning is ... -
Optimization of alkaline cellulase production by the marine-derived fungus Chaetomium sp. using agricultural and industrial wastes as substrates
(Walter de Gruyter, 2010)Alkaline cellulases were screened from 54 fungal isolates obtained from mangrove leaves and mangrove wood litters as endophytes and wood litter fungi, respectively. Only three fungal isolates tested positive for alkaline ... -
Optimization of the taxonomic resolution of an indicator taxon for cost-effective ecological monitoring: Perspectives from a heterogeneous tropical coastline
(2019)An important requirement towards formulating appropriate management and conservation measures for biological diversity is to devise efficient and cost-effective monitoring protocols that yield coherent data. Environmental ... -
Optimization of urease production by Bacillus halodurans PO15: a mangrove bacterium from Poovar mangroves, India
(Springer Science and Business Media LLC, 2020)Mangrove ecosystems are one of the most versatile habitats for microorganisms with a high potential for producing a variety of extracellular hydrolytic enzymes. In this study, bacteria with urease activity, enzymes that ... -
Optimum sampling interval for evaluating ferromanganese nodule resources in the central Indian Ocean
(Springer, 2001)A study to estimate manganese nodule abundance (weight of nodules in kg/m sup(2)) was carried out in a small area of the abyssal plains covering a one-degree square block in the central Indian Basin. Abundance was assessed ... -
Orbital frequencies in radiolarian assemblages of the central Indian Ocean: implications on the Indian summer monsoon
(Elsevier, 2003)Radiolarian distribution in surface sediments and its relationships with overlying surface oceanography provided impetus for down-core faunal variation related to changes in monsoon intensity due to the Earth's orbital ... -
Ordinary chondritic micrometeorites from the Indian Ocean
(The Meteoritical Society, 2015)Extraterrestrial particulate materials on the Earth can originate in the form of collisional debris from the asteroid belt, cometary material, or as meteoroid ablation spherules. Signatures that link them to their parent ... -
Ore grade manganese nodules from the central Indian basin: an evaluation
(1989)Comparative studies on manganese nodules from two different areas (S and R) in the Central Indian Basin show distinct variations in their composition, grade (percent Ni + Cu), and abundance (kg/m2), which are explained in ... -
