Abstract The COVID-19 epidemic-led lockdown (LD) from March 25 to May 31, 2020, had a different level of impact on air quality in the ecologically sensitive region of northeast India, even though the restriction on main anthropogenic activities was expected to reduce particulate matter concentration. The daily average black carbon concentration mea...

Abstract The proper functioning of the river ecosystem has been symbolised by healthy aquatic life. The river Ganga has shown signs of rejuvenation due to lockdown. In this study, an attempt has been made to analyse the change in river water quality using Sentinel-2 and Landsat-8 imageries. The quantitative analysis has been performed for temperatu...

Seismographs record earthquakes and also record various types of noise, including anthropogenic noise. In the present study, we analyse the influence of the lockdown due to COVID-19 on the ground motion at CSIR-NGRI HYB Seismological Observatory, Hyderabad. We analyse the noise recorded a week before and after the implementation of lockdown by esti...

Carbon and oxygen isotopic ratios of foraminiferal test are exclusively used for tracing the past changes in ocean circulation, air–sea exchange, global carbon cycle and temperature variations of water masses. Here we present the carbon and oxygen isotopic ratios of benthic foraminifera from sediment core AAS-9/21 retrieved from a water depth of 18...

AbstractRiver channel migration is a disastrous phenomenon in many parts of the world. It results in large-scale damage to the infrastructure, loss of lives and significantly affects livelihood. It also brings rapid and random changes in land use and land cover (LULC). Jiadhal river is a river of this kind in eastern India. It experiences frequent ...

Despite the advent of towing conductivity, temperature and depth (CTD) sensors, expendable bathythermographs (XBTs) and expendable CTDs (XCTDs) are still employed as an easy and effective means to collect temperature profiles in the ocean from a moving ship. Since these expendable probes do not have any pressure sensor, it infers depth from the tim...

The present study mainly focuses on the effect of temperature enhancement on local weather due to the heat emitted from anthropogenic sources with a numerical weather prediction model. In this study, anthropogenic heat (AH) flux is mainly considered as heat generated due to industrial action in the urban area. Angul district located between 20.41–2...

AbstractA complex magma mingling/interaction zone in the Bundelkhand craton, Central India, was formed when several pulses of mafic magma interacted with the still-crystallising felsic magma. Coeval emplacements of mafic−felsic magmas (marked by the cuspate−lobate boundary, crystal transfer, and hybrid rocks) produce various styles of interactions ...

AbstractThe metallurgical processes in production of iron and steel from ores produce slags (blast furnace slag and basic oxygen furnace slag), which is usually dumped as solid waste by various steel plants around the world. The present study assessed and estimated the impact of slag dump piling up for the last 60 years on the hydrogeological envir...

The Deccan volcanic province (DVP) is one of the largest igneous provinces of the world and occupies almost 15% of the landmass of India. It is fascinating not only because of its size, but also due to its varied nature of basement and potentiality for mineral resources. The analysis of regional and residual gravity anomalies indicated sub-surface ...
