Evaluating the estuarine tidal discharge through water stage component analysis and in-situ measurement - Case study Mandovi-Zuari estuary of Goa, India
(Elsevier, 2023)Determining tidal reach and long-term monitoring of tidal discharge are vital in an estuarine system due to their potential use in water resource management and inland navigation. The upstream river discharge contributes ... -
Seasonal distribution of cirrus cloud characteristics and their rapid descent from polarization lidar measurements at the west coast of India
(Springer, 2023)Cirrus clouds are highly reflective clouds that play an important role in the atmospheric radiative balance and contribute to climate change. We present the seasonal distribution of cirrus cloud occurrence, characteristics ... -
Surviving in a warming and crowded world: a review of Irrawaddy dolphin in Asia’s largest brackish water lagoon
(Springer, 2023)In human-altered environments, wildlife is impacted by a range of factors; therefore, understanding on responsible factors can aid in developing conservation strategies. Irrawaddy Dolphins (IRD: Oracella brevirostris) are ... -
Response of oceanic subsurface chlorophyll maxima to environmental drivers in the Northern Indian Ocean
(Elsevier, 2024)Subsurface Chlorophyll Maxima (SCM) contributes a significant proportion to depth-integrated ocean primary production, making it important to understand its spatiotemporal variability in changing environmental conditions. ... -
Distribution and antibiotic resistance of vibrio population in an urbanized tropical lake-the Vembanad-in the southwest coast of India
(Springer, 2023)Among the diverse Vibrio spp. autochthonous to coastal ecosystems, V. cholerae, V. fluvialis, V. vulnificus and V. parahaemolyticus are pathogenic to humans. Increasing sea-surface temperature, sea-level rise and water-related ... -
Spatial and temporal variation of dissolved iodine in the eastern Arabian Sea
(Elsevier, 2023)Here we report the seasonal and spatial variation of iodide (I−) and total dissolved iodine (TI) along a transect covering the oxygen minimum zone (OMZ) in the Arabian Sea (AS). This data is generated after a gap of more ... -
Coupling between chromophoric dissolved organic matter and dissolved inorganic carbon in Indian estuaries
(Elsevier, 2023)This study investigates the coupling between Chromophoric Dissolved Organic Matter (CDOM) and Dissolved Inorganic Carbon (DIC) in eighteen Indian estuaries across salinity gradient of the east and west coasts during the ... -
Spatial variability in plankton metabolic balance in the tropical Indian Ocean during spring intermonsoon
(Elsevier, 2023)The tropical Indian Ocean consists of three basins, namely the Arabian Sea (AS), Bay of Bengal (BoB) and Southern Indian Ocean (SIO), with relatively nutrient-rich waters in the former two basins. It is hypothesized that ... -
Microbial distribution and diversity along a vertical profile in the water column of a seasonal Oxygen minimum zone in the Southeast Arabian Sea
(Elsevier, 2023)The Oxygen Minimum Zones (OMZ) support a milieu of microbial communities capable of degrading complex molecules. The current study reports the vertical distribution of microorganisms and diversity of bacteria in Arabian ... -
Southeastern Arabian Sea Salinity variability: mechanisms and influence on surface temperature
(Springer, 2023)Previous studies suggest that the winter surface freshening in the southeastern Arabian Sea (SEAS) contributes to the development of very high Sea Surface Temperatures (SST) thereby influencing the following summer monsoon ... -
Risk assessment of polycyclic aromatic hydrocarbon infested sediments along the coast of Goa, India
(Springer, 2023)Goa, a small state in India, is a tourist hotspot known for its coastline and beaches. Anthropogenic activities lead to pollution in the environment. Amongst many other pollutants, polycyclic aromatic hydrocarbons represent ... -
Period and length of high surface gravity waves measured in the coastal waters of eastern Arabian Sea and its variations in 10 years
(Elsevier, 2023)Information on the period and length of waves is required for the planning and design of marine facilities and wave energy converters. In this article, the period and length of the waves measured during the peak monsoon ... -
Role of subsurface layer temperature inversion in cyclone induced warming in the northern Bay of Bengal
(Elsevier, 2023)Subsurface Layer Temperature Inversion (SLTI) is a prominent physical process occurring in the Bay of Bengal (BoB) during winter. BoB also witnesses intense cyclones during winter (post-monsoon). Sidr is a category-5 cyclone ... -
Report of epibiont Thecacineta oregonensis (Ciliophora: Suctorea) on Desmodora sp. (Nematoda) at 990 m depth from seamount flank of the Andaman Sea, Indian Ocean
(Station Biologique de Roscoff Institute, Roscoff, France, 2023)Suctorian epibionts Thecacineta oregonensis (Murphy, 1965) attached on the cuticle of nematode Desmodora sp. is reported here from the seamount area of the Andaman Sea at 990 m depth. The T. oregonensis is reported here ... -
Eastern Arabian Sea CO2 outgassing during the last deglaciation and Holocene related to deep-water carbonate chemistry
(Elsevier, 2023)Glacial to interglacial changes in atmospheric CO2 are an intriguing part of carbon reorganization in the climate system and are estimated by investigating deep-water carbonate ion concentrations ([CO32−]). The scarcity ... -
Contribution of tropical cyclone induced waves to the mean and extreme wave climatology in the Bay of Bengal
(Elsevier, 2023)This paper examines the contribution of tropical cyclones (TCs) to the mean wave and the extreme wave climatology in the Bay of Bengal (BoB). To assess the impact of TCs on the wave activity in the BoB, we compare 40-years ... -
ESIPT-based probes for cations, anions and neutral species: Recent progress, multidisciplinary applications and future perspectives
(The Royal Society of Chemistry, 2023)Fluorescent and colourimetric probes for small analytes (cations, anions and neutral molecules) have drawn significant attention in recent years. These probes interact with analytes and induce spectral change due to the ... -
Factors influencing nearshore hypoxia in the southeastern Arabian Sea: A sensor-based study
(Elsevier, 2023)Seasonal upwelling and the associated incursion of hypoxic waters into the coastal zone is a widely studied topic over different upwelling zones. However, its persistence or variations over short time scales are poorly ... -
