Carbon Dioxide Concentration Mechanisms in Natural Populations of Marine Diatoms: Insights From Tara Oceans
(Frontiers Media S.A., 2021)Marine diatoms, the most successful photoautotrophs in the ocean, efficiently sequester a significant part of atmospheric CO2 to the ocean interior through their participation in the biological carbon pump. However, it is ... -
Geochemistry of aerodynamically distorted Australasian microtektites: Implications for ejecta on Mars and Venus
(Springer, 2021)We report microtektites recovered from a large area of the deep seafloor (Central Indian Ocean) that appear to have undergone aerodynamic distortion during re-entry into the atmosphere. Considering the geographic locations, ... -
Tuning the extraction mechanism of uranyl ion in bicyclooctanium, propylpyridinium, piperidinium and imidazolium based ionic liquids: First ever evidence of �cation exchange�, �anion exchange� and �solvation� mechanism
(Elsevier BV, 2021)A novel diamide ligand, 5-bromo-N1, N3-diisopropylisophthalamide has been synthesized and characterized by FTIR, 1H NMR, and 13C NMR. The extraction mechanism of uranyl ion with the diamide ligand has been studied in ... -
Wave Climate Variability and Occurrence of Mudbanks Along the Southwest Coast of India
(Frontiers Media S.A., 2021)Mudbanks (MBs) are a natural phenomenon, forming along the southwest coast of India during southwest monsoon (SWM), almost every year. High waves initiate these formations. The temporal variability (both intra-annual and ... -
Glass spherules from Antarctica blue ice and deep-sea sediment of the Central Indian Ocean Basin
(Springer, 2021)We report the chemical composition of 176 glass spherules obtained from Antarctica blue ice and deep-sea sediments from the Central Indian Ocean Basin. This study compares the chemistry of glass spherules collected from ... -
Microplastics as an emerging source of particulate air pollution: A critical review
(Elsevier, 2021)Accumulation of plastic litter exerts pressure on the environment. Microplastics (MPs) pollution has become a universal challenge due to the overexploitation of plastic products and unsystematic dumping of plastic waste. ... -
A comparative study on microzooplankton communities in two tropical monsoonal estuaries
(Elsevier, 2021)We studied on microzooplankton (MZP) communities from two major rivers, the Mandovi and the Zuari estuarine system of Goa on central west coast India. Despite both estuaries having a common point of discharge (eastern part ... -
Coccolithophores: an environmentally significant and understudied phytoplankton group in the Indian Ocean
(Springer, 2021)Coccolithophores are unique primary producers in the ocean with the ability to calcify. They are known to produce calcareous scales, which form the significant part of calcite oozes or chalk deposits on the seafloor. ... -
Late Quaternary record of Indian summer monsoon-induced stratification and productivity collapse in the Andaman Sea
(John Wiley and Sons, Ltd, 2021)During each summer monsoon, the northeastern Indian Ocean receives a huge amount of rain and river discharge, resulting in strong stratification and prevalence of oligotrophic conditions. These water column changes impact ... -
The Sino-Indian Geopolitics and Maritime Security of the Indian Ocean Region
(Taylor and Francis, 2021)The Indian Ocean Region (IOR) is a prominent arena in international politics, in terms of trade, tourism, population, among other aspects. Several countries, some unconnected geographically, have shown interest in these ... -
Velocity modeling and attribute analysis to understand the gas hydrates and free gas system in the Mannar Basin, India
(Elsevier, 2021)The Mannar basin, located between India and Sri Lanka, is poorly explored for hydrocarbon compared to other petroliferous basins in the Indian offshore. 2D multichannel seismic data was acquired onboard R/V Samudra Ratnakar ... -
Trace metals concentration in water hyacinth implicates the saltwater barrage altered hydrography of Kochi backwaters, southwest Coast of India
(Elsevier, 2021)This study in the Kochi backwaters (KBW) presents the distribution of 9 trace metals (Fe, Zn, Cu, Mn, Ni, Co, Cr, Cd, Pb) in different parts (root, stolon and leaf) of the common water hyacinth Eichhornia crassipes during ... -
Two decades of current observations in the equatorial Indian Ocean
(Springer, 2021)Deep-sea moorings in the equatorial Indian Ocean were first deployed by India in the year 2000, and currents were measured at three locations (77°E, 83°E, and 93°E) on the equator. In this paper, we present two decades of ... -
Influence of phytoplankton pigment composition and primary production on pCO2 levels in the Indian Ocean
(Springer, 2021)The tropical Indian Ocean is a net sink for the carbon dioxide (CO2) in the atmosphere and phytoplankton production plays a crucial role in CO2 fixation and determines the direction of CO2 flux at the sea-to-air interface. ... -
Seaweed-based cellulose: Applications, and future perspectives
(Elsevier, 2021)Cellulose is a naturally occurring organic polymer extracted mainly from lignocellulosic biomass of terrestrial origin. However, the increasing production of seaweeds for growing global market demands has developed the ... -
Sedimentological responses to coastal dynamics along the Thane District, North Maharashtra, West Coast of India
(Springer, 2021)We present the results of sedimentological responses to coastal dynamics of the Arnala beach, located between Vaitarna and Ulhas rivers, Thane district, Maharashtra, India. The coast is remarkably flat and wide and in the ... -
Response of macrozoobenthic communities to summer monsoon upwelling and related hypoxia in the south eastern Arabian Sea shelf
(Elsevier, 2021)Coastal upwelling in the south eastern Arabian Sea (SEAS) leads to oxygen depletion over the continental shelf during the summer monsoon season (June-September), with latitudinal gradients in intensity. Based on two surveys ... -
Phosphorus cycling from a coastal upwelling zone in the Southeastern Arabian Sea
(Springer, 2021)The present study examined the seasonal cycling of phosphorous (P) along the southwest coast of India (SWCI) based on two cruises during the southwest monsoon (SWM) and northeast monsoon (NEM) of 2018. During SWM, the ... -
Controls of mass transport deposit and magnetic mineral diagenesis on the sediment magnetic record from the Bay of Bengal
