Impact of salinity on the grazing rate of a cladocera (Latonopsis australis) in a large tropical estuarine system
(2020)Cladocerans are ecologically important as active grazers at the secondary trophic level, and they are economically important in aquaculture as potential live feed for many commercially valuable fishes. This study deals ... -
Change of lithofacies in marine sediment core from Quaternary to Pre-Quaternary: A case study from the Central Indian Ocean Basin
(2020)A distinct change in lithofacies was observed from red clay to siliceous ooze in a core from Indian Ocean. Radiolarian index species were used to ascertain the Quaternary datum levels and an age of 2.0 Ma is determined up ... -
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 ... -
Spatial and temporal variability in concentration and characteristics of aerosols at Visakhapatnam (east) and Goa (west) coasts of India
(2020)Knowledge on the variability in quantity and compositions of various size groups of aerosols is important to understand their sources and their role in biogeochemical and climate processes. Here, we studied total suspended ... -
Phytoplankton associated with seasonal oxygen depletion in waters of the western continental shelf of India
(2020)We report here results of a time series study carried out to understand seasonal variability of phytoplankton in relation to changes in dissolved oxygen based on observations at the Candolim Time Series (CaTS) station ... -
Dominance of Wolbachia sp. in the deep-sea sediment bacterial metataxonomic sequencing analysis in the Bay of Bengal, Indian Ocean
(2020)The Bay of Bengal, located in the north-eastern part of the Indian Ocean is world's largest bay occupying an area of ~8,39,000 mile2. The variability in bacterial community structure and function in sediment ecosystems of ... -
On the generation and propagation of Makran swells in the Arabian Sea
(2020)Persistent and periodic northerly low-level jets have been identified in the South Asian mid?latitudes and subtropics, which are modified by the presence of Makran mountain ranges adjacent to the central south coast of ... -
Climatology and trends of the Indian Ocean surface waves based on 39-year long ERA5 reanalysis data
(2020)In this study, the wind and the surface waves in the Indian Ocean (IO) during 1979-2017 are studied based on the ECMWF ERA5 Reanalysis data. Long?term statistical analysis of extreme waves is carried out based on Generalized ... -
Effects of salinity and temperature on the acute toxicity of the pesticides, dimethoate and chlorpyrifos in post-larvae and juveniles of the whiteleg shrimp
(2020)In this article, the acute toxicity of the organophosphorus pesticides (OPs), dimethoate (DMT) and chlorpyrifos (CPF) in post-larvae, and juveniles of Litopenaeus vannamei at different ambient salinity (5, 15 and 25) and ... -
Contrasting features of tropospheric turbulence over the Indian peninsula
(2020)Altitude structure of turbulence in the troposphere and lower stratosphere (TLS) over the Indian peninsula is delineated using radiosonde observations carried out from six stations (August 2013 to December 2017) as part ... -
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 ... -
High abundance of Vibrio in tarball-contaminated seawater from Vagator beach, Goa, India
(2020)Tarballs are semi-solid remnants of crude oil and they are formed in marine environment after oil-spill incidents. They are composed of diverse hydrocarbons; some of which are recalcitrant in nature. Recent studies based ... -
Assessment of crustal element and trace metal concentrations in atmospheric particulate matter over a coastal city in the Eastern Arabian Sea
(2020)Major/crustal elements (Al, Ca, Mg, K and Fe) and trace metals (Mn, Cr, Cu, Pb, Zn, and Ni) in atmospheric particulate matter at three sites in Goa (a coastal city in the Eastern Arabian Sea) were assessed during winter ... -
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), ... -
