Occurrence of white gelatinous foam on the beaches of Kollam (southwest coast of India) due to the senescent bloom of Phaeocystis globosa
(Current Science Association, IAS, 2020)
An unusual white gelatinous foam (~2 ft high) was detected on the beaches of Kollam (Mundakkal), Kerala, southwest coast of India. It extended to ~300 m alongshore on 10 June 2019 from 7 am and sustained till around 10 am. ...
Benthic-pelagic coupling assessed using phytoplankton marker pigments: a case study from the Paradip port, East Coast of India
(Springer, 2022)
This study addresses the seasonal distribution of phytoplankton marker pigments (PMP) and the ratios (indicating freshness and fate) from water and surface sediments from the coastal port ecosystem (Paradip port, Odisha, ...
Chemical composition of Low Moor and Walker Company cannons in the Odisha State Maritime Museum, east coast of India
(Current Science Association, IAS, 2022)
Cannons are military or civil weapons supported on carriages or fixed mounts and used in warfare as well as against rebellions. Now, most of the cannons are exhibited in museums, forts, public and private buildings , and ...
In-situ O-isotope analysis of relict spinel and forsterite in small (<200µm) Antarctic micrometeorites - Samples of chondrules & CAIs from carbonaceous chondrites
(Elsevier, 2022)
We report high-precision secondary ion mass spectrometer triple oxygen isotope systematics (95 individual analyses) from 37 micrometeorites (MMs) collected from South Pole Water Well (SPWW), Antarctica. The study population ...
Conjugate nature of the Alleppey-Trivandrum Terrace Complex with the Northern Madagascar Ridge in the early opening model of the Arabian Sea: evaluation based on an integrated geophysical investigation
(Springer, 2022)
The southwestern continental margin of India reveals the presence of an anomalous bathymetric high feature located in the mid-continental slope region off Trivandrum. Based on the analysis of the available geophysical data ...
Seasonal variability in environmental parameters influence bacterial communities in mangrove sediments along an estuarine gradient
(Elsevier, 2022)
Mangrove ecosystems are repositories of divergent microbial communities which respond differently to environmental characteristics. Hence, it is important to understand the community structure with respect to pertinent ...
A Path-Following Controller for Marine Vehicles Using a Two-Scale Inner-Outer Loop Approach
(MDPI, 2022)
This article addresses the problem of path following of marine vehicles along straight lines in the presence of currents by resorting to an inner-outer control loop strategy, with due account for the presence of currents. ...
Nitrogen fixation in the western coastal Bay of Bengal: Controlling factors and contribution to primary production
(Elsevier, 2022)
N2 fixation rates were measured at 18 stations in the western coastal Bay of Bengal (BoB) to evaluate its contribution to the external source of nitrogen and its controlling factors. During the study period (fall monsoon), ...
Dark survival in biofilm-forming microalgae: potential for colonizing benthic ecosystems
(Oxford Academic, 2022)
The biofilm-forming microalgae are known to experience periods of continuous darkness (upto several days), in addition to the natural day-night cycle, especially in the intertidal sediment regions (when transported to ...
Phytoplankton assemblage and chlorophyll a along the salinity gradient in a hypoxic eutrophic tropical estuary-Ulhas Estuary, West Coast of India
(Elsevier, 2022)
Phytoplankton assemblage and chlorophyll a along the salinity gradient and oxygen zonation were studied in Ulhas Estuary. Oxic condition exist in euhaline region of the estuary that receives oxygenated coastal waters, ...
