The Oxygen Isotope Compositions of Large Numbers of Small Cosmic Spherules: Implications for Their Sources and the Isotopic Composition of the Upper Atmosphere
(American Geophysical Union (AGU), 2020)
Cosmic spherules are micrometeorites that melt at high altitude as they enter Earth’s atmosphere and
their oxygen isotope compositions are partially or completely inherited from the upper atmosphere,
depending on the ...
Factors structuring spatio-temporal dynamics of macrobenthic communities of three differently modified tropical estuaries
(2020)
Tropical estuaries of industrialized northwest coast of India, subject to seasonal and multifarious anthropogenic interventions, are poorly studied. Three estuaries, Ulhas, Amba and Savitri were investigated seasonally to ...
Ecology and distribution of tanaids in a large tropical estuary along the Southwest Coast of India
(2020)
The crustacean order Tanaidacea consists of macrobenthic invertebrates, which constitute a major food source for higher trophic levels in estuarine and marine environments. Based on seasonal sampling in the Kochi Backwaters ...
Increased Ventilation of the Northern Indian Ocean during the Last Deglaciation
(Springer, 2020)
This paper gives an overview of the deep-water ventilation studies carried out over the world oceans using radiocarbon. There is a consensus that aged water mass existing in the abyssal ocean during the last glacial, ...
A new species of the genus Corynophrya (Ciliophora: Suctorea) from the west coast of India, Arabian Sea
(CNRS - Station Biologique de Roscoff - ABiMS, Roscoff, France, 2020)
The article presents the description of a new species of the suctorian genus Corynophrya inhabiting the body surface (cuticle) of harpacticoid copepod from the west coast of India, Arabian Sea. The diagnosis of the genus ...
Phthalic acid esters - A grave ecological hazard in Cochin estuary, India
(2020)
Distribution and ecological risks of Phthalic acid esters (PAEs) are poorly studied in estuarine environments in India. An attempt is made to chart the sources and assess the ecological risk of six PAE congeners (Σ6PAEs), ...
Extending the limit of widespread dispersed Toba volcanic glass shards and identification of new in-situ volcanic events in the Central Indian Ocean Basin
(Springer, 2020)
We report the widespread extent of Toba volcanic glass shards in the Central Indian Ocean Basin. Investigation of four sediment cores (7o-17oS) revealed several shard-rich horizons (SRH) that provide the first detailed ...
Hilbert-Huang transform analysis of surface wavefield under tropical cyclone Hudhud
(Elsevier Ltd, 2020)
The characteristics of an evolving ocean surface wavefield under tropical cyclone Hudhud that took place in October 2014 are investigated. The Hilbert-Huang transformation (HHT) is used for the spectral analysis of the ...
Functional and taxonomic (? and ?) diversity patterns of macrobenthic communities along a depth gradient (19-2639 m): A case study from the southern Indian continental margin
(Elsevier Ltd, 2020)
Identifying the drivers that shape the biodiversity of a region is important to predict the response of ecosystems to environmental changes. Macrofaunal distribution pattern in the North Indian Ocean has so far been mainly ...
Design and development of pressure sensor based on Fiber Bragg Grating (FBG) for ocean applications
(EDP Sciences, 2020)
Reactively evaporated TiO2 thin films were deposited on the glass substrate by electron beam heating technique. In the first stage evaporation rates are varied keeping substrate temperature fixed at 200 C and oxygen flow ...
