n-Alkanes in surficial sediments of Visakhapatnam harbour, east coast of India
(Indian Academy of Sciences, 2013)Surface sediments collected from 19 stations along Visakhapatnam harbour were analysed for organic carbon (OC), delta sup(13)C sub(oc), total lipids (TL), total hydrocarbon (THC), n-alkane concentration and composition. ... -
N2 production rates limited by nitrite availability in the Bay of Bengal oxygen minimum zone
(Macmillan Publishers Limited, 2017)A third or more of the fixed nitrogen lost from the oceans as N<sub>2</sub> is removed by anaerobic microbial processes in open ocean oxygen minimum zones. These zones have expanded over the past decades, and further ... -

Nannoplankton from RC9-156 in the southeastern Arabian Sea
(Geological Society of India, 1983)A deep sea core RC9-156 collected in the Arabian Sea at a water depth of 4583 m was analysed for calcareous nannoplankton and dissolution studies. Twelve species of nannoplankton were identified and based on the assemblage, ... -
Nannoplankton from Recent Sediments off the Andaman Islands
(CSIR-NISCAIR, 1981)Sixteen sediment samples have been investigated for the distribution of nannoplankton. Of the total 38 species encountered, 14 are modern and remaining 24 are reworked fossils ranging in age from Eocene to Pliocene. Majority ... -
Nannoplankton from the Bombay-Saurashtra continental shelf of India: An appraisal using cluster analysis
(Indian Association for Limnology and Oceanography, 1984)Nannoplankton data from 28 stations in the northwestern continental shelf of India was subjected to Q-mode cluster analysis. Two biotopes A and B were identified. Although, Gephyrocapsa oceanica was by far, the most abundant ... -

Nannostructure and significance of fish coprolites in phosphorites
(Elsevier, 1994)Phosphatic coprolites (0.5-2 cm long) occurring in Cretaceous-Eocene phosphorites of Tunisia, Morocco, Mauritania, Senegal, and Egypt were investigated for their petrology by using SEM. They exhibit a homogeneous porous ... -
Nanomaterials for Fluorescence and Multimodal Bioimaging
(Wiley, 2023)Bioconjugated nanomaterials replace molecular probes in bioanalysis and bioimaging in vitro and in vivo. Nanoparticles of silica, metals, semiconductors, polymers, and supramolecular systems, conjugated with contrast agents ... -
Naphthalene induced activities on growth, respiratory metabolism and biochemical composition in juveniles of Metapenaeus affinis (H.Milne Edward, 1837)
(NISCAIR, CSIR, 2010)Toxicity of naphthalene was carried out on Metapenaeus affinis (H. Milne Edward, 1837) to investigate its effects on growth, metabolic index and biochemical constituents. Growth rate in terms of weight gain was 32.13% in ... -

National oceanographic information system
(Indian Library Association, 1991)Ocean study is inherently interdisciplinary and therefore calls for a controlled and integrated approach for information generation, processing and decision making. In this context, Indian National Oceanographic Data Centre ... -

Native aluminium (spherules and particles) in the central Indian Basin sediments: Implications on the occurrence of hydrothermal events
(Elsevier, 2007)We have sampled particles of native aluminium (Alº) in two sediment cores from the Central Indian Basin (CIB). The cores are geographically separated but are located at the base of two seamounts. The native Alº particles ... -
Natural and human-induced hypoxia and consequences for coastal areas: Synthesis and future development
(European Geosciences Union, 2010)Hypoxia has become a world-wide phenomenon in the global coastal ocean and causes a deterioration of the structure and function of ecosystems. Based on the collective contributions of members of SCOR Working Group 128, the ... -
Natural decadal sea-level variability in the Indian Ocean: lessons from CMIP models
(2019)Indian Ocean decadal sea-level variability is an active research area, with many unresolved questions due to inadequate observational coverage. In this study, we analyse 26 Coupled Model Intercomparison Project (CMIP) ... -
Natural diet of the alligator pipefish, Syngnathoides biaculeatus (Bloch, 1785) inhabiting Palk Bay, southeast coast of India
(NISCAIR-CSIR, India, 2018)A total of 56 guts of the alligator pipefish, Syngnathoides biaculeatus collected from Palk Bay, southeast coast of India were analysed for determining its natural diet composition. The gut fullness index as assessed by ... -
Natural hazards, disasters and human kind: Whither ecosystem management?
(Cafet-Innova Technical Society, 2013)Natural hazards such as yearly storm surges that create irreplaceable damage, the December 2004 tsunami that demolished large parts of the Indian coast, and the June 2013 Himalayan floods that swept river banks proved yet ... -
