Production of quality biomass of Gelidium micropterum K tzing through optimization of nutrients and salinity for sustainable land-based cultivation
(Springer, 2024)In this study, the seeding density (w/v), Provasoli Enriched Seawater (PES) medium strength, and salinity of the culture medium were optimized to obtain higher growth rates and superior biomass quality of Gelidium micropterum ... -
Discovery of fossil micrometeorites from the Deccan trap intertrappeans
(Wiley Online Library, 2024)Abstract The Cretaceous?Paleogene (K-Pg) boundary represents the extinction of ~70% of species, a prominent Chicxulub impact event and Deccan volcanism. This work reports the first attempt to extract the micrometeorites ... -
Investigating the evolution of sand bars and natural channel formation in the Mandovi estuary along the central west coast of India
(Elsevier, 2024)Coastal formations, such as sandbars, play a vital role in shaping the environment and maintaining local and regional coastal morphology. This study deals with two noteworthy sandbars, namely Aguada and Reis Magos which ... -
Tracing marine and terrestrial biochemical signatures of particulate organic matter in an Arctic fjord (Kongsfjorden)
(Elsevier, 2024)Arctic fjords are hotspot for organic matter (OM) transformation and storage, however, the composition and sources of the particulate organic matter (POM) are still not completely understood. Further, due to the ongoing ... -
A Northgrippian sedimentary magnetic enhancement along the western margin of India
(Elsevier, 2024)Sedimentary magnetic records of shelf region contains complex environmental evolution information, necessitating records from various global regions to accurately interpret its significance. A sediment core (SSD-39/GC-01) ... -
Assessment of Benthic Meiofauna in Multi-Stressed Environment of a Tropical Estuary: a Case Study Using Low Taxonomic Resolution Data
(Springer, 2024)The estuary receives varying anthropogenic inputs that significantly influence the benthic biota and suppress ecological health. Thus, multiple parameters (natural and anthropogenic) and meiofaunal community structures ... -
Seasonal shift in trophic status induced by bacterial metabolic activity in tropical mangrove-dominated estuaries of Southwest India
(Springer, 2024)Mangroves are highly productive ecosystems that supply carbon and nutrients to the coastal food web from autochthonous and allochthonous sources. The fluctuations in the quantity of these sources influence bacterial metabolic ... -
Analyzing the rainfall trend and hydroclimatic teleconnections using Hilbert Huang Transform for the coastal smart cities of India
(Elsevier, 2024)The changing climatic patterns associated with intense and erratic rainfall have led to high flooding risk in urban areas. Identifying these hydro-meteorological risks in cities is a matter of concern for decision-makers. ... -
Polycyclic aromatic hydrocarbons in surface sediments of the western Bay of Bengal: Distribution, sources, and ecological risk assessment
(Elsevier, 2024)This study investigated the distribution, sources, and ecological risk of polycyclic aromatic hydrocarbons (PAHs) in the surface sediments of the Western Bay of Bengal (WBoB). Coastal, shelf and slope sediments from the ... -
Substantial invasion of Antarctic Intermediate Water into the Arabian Sea during Younger Dryas and Heinrich Stadials
(Elsevier, 2024)Antarctic Intermediate Water (AAIW) is an important component of the global thermohaline circulation and an essential limb of the Atlantic Meridional Overturning Circulation (AMOC), which redistributes heat, oxygen, and ... -
Wave energy potential along the Indian coast: A comprehensive review
(Elsevier, 2024)Wave energy is rapidly emerging as a promising and innovative solution among the various renewable energy sources. Given India's extensive coastline, including islands, research on wave energy is essential to harness this ... -
An evaluation of glass beads from the southwestern coastal state of Goa, India, as a potential pollutant in marine ecosystem
(Springer, 2024)Glass beads laid on the road, mainly used for better visibility, can contribute to harmful anthropogenic waste to the marine environment, and it is a prerequisite to distinguish the chemical properties associated with it. ... -
Application of functional metagenomics in the evaluation of microbial community dynamics in the Arabian Sea: Implications of environmental settings,
(Elsevier, 2024)Ocean microbial communities form the base of marine food webs, facilitating energy transfer and nutrient cycling, thereby supporting higher trophic levels. We investigated their composition and functional profiles across ... -
Mass Balance Assessment Using the AARTI Approach in the Baspa Basin, Indian Himalayas
(Springer, 2024)Snow cover and glaciers are the major sources of freshwater from the Polar Regions, Antarctica, Himalaya and the Arctic. Melt from these glacial components forms the supply of water to the downstream communities for various ... -
Assessment of transboundary macro-litter on the remote island of Andaman and Nicobar: Unveiling the governing factors and risk assessment
(Elsevier, 2024)The increasing occurrence of mismanaged plastic litter along India's coastline and the ominous challenges it poses to biodiversity and ecosystem health is a growing environmental concern. To address this issue, we ... -
Size-Fractionated Phytoplankton Biomass in Port Blair Bay, South Andaman Island: Spatial Variability and Environmental Control
(Springer, 2024)Island bays show different physico-chemical characteristics due to their connection with open ocean water and small catchment area, and the same is expected with the biological forms. Phytoplankton size structure significantly ... -
Dissolved and suspended nutrient complexity in an urbanized creek-estuary confluence: Implication on water quality alteration
(Elsevier, 2024)The Thane Creek-Ulhas estuary confluence region acts as a naturally active infiltration system, crucial for altering water quality in the area and Arabian Sea. Particle-water exchange, hydrodynamics, and anthropogenic ... -
