Fungal diversity notes 1-110: Taxonomic and phylogenetic contributions to fungal species
(Springer, 2015)This paper is a compilation of notes on 110 fungal taxa, including one new family, 10 new genera, and 76 new species, representing a wide taxonomic and geographic range The new family, Paradictyoarthriniaceae is introduced ... -
Biochemical and stable carbon isotope records of mangrove derived organic matter in the sediment cores
(Springer, 2016)Core sediments from five mangrove ecosystems along northern Kerala Coast were collected to evaluate the nature and sources of organic matter in these ecosystems. General sedimentary parameters (pH, Eh, grain size and total ... -
A comparison of Mg/Ca ratios in Globigerinoides ruber (white): sensu stricto versus a mixture of genotypes
(Geological Society of India, 2016)Mg/Ca ratios were measured in core AAS9/21 from the eastern Arabian Sea (EAS), on two sets of planktonic foraminifera, one with a mixture of Globigerinoides ruber genotypes (sensu stricto and sensu lato) and the second ... -
DNA damage and oxidative stress in marine gastropod Morula granulata exposed to phenanthrene
(Springer, 2016)DNA damage and oxidative stress in marine gastropod Morula granulata was measured after in vivo exposure to four different concentrations (10, 25, 50, and 100 mikrog/L) of phenanthrene. Comet assay was used for measurement ... -
Tumour-like anomaly of copepods-an evaluation of the possible causes in Indian marine waters
(Springer, 2016)Globally, tumour-like anomalies (TLA) in copepods and the critical assessment of their possible causes are rare. The exact causative factor and ecological consequences of TLA in copepods are still unclear and there is no ... -
Intraseasonal variability of mixed layer depth in the tropical Indian Ocean
(Springer, 2016)In this paper, we use an observational dataset built from Argo in situ profiles to describe the main large-scale patterns of intraseasonal mixed layer depth (MLD) variations in the Indian Ocean. An eddy permitting (0.25°) ... -
Assessment of seasonal and year-to-year surface salinity signals retrieved from SMOS and Aquarius missions in the Bay of Bengal
(Taylor & Francis, 2016)The Bay of Bengal (BoB) exhibits a wide range of sea surface salinity (SSS), with very fresh water induced by heavy monsoonal precipitation and river run-offs to the north, and saltier water to the south. This is a ... -
Morphotectonic and petrological variations along the southern Central Indian Ridge
(Springer, 2016)In order to ascertain the effect of geomorphic and tectonic domains on the formation, enrichment, and ascension of the ridge axis melt, structural and petrological data from a nearly 300-km-long axial stretch along the ... -
Residual estuarine circulation in the Mandovi, a monsoonal estuary: A three-dimensional model study
(Elsevier, 2016)Observations in the Mandovi estuary, located on the central west coast of India, have shown that the salinity field in this estuary is remarkably time-dependent and passes through all possible states of stratification ... -
Spatial variability in phytoplankton community structure along the eastern Arabian Sea during the onset of south-west monsoon
(Elsevier, 2016)The Arabian Sea experiences moderate to weak upwelling along the south-west coast of India, which subsequently propagates towards the north. This causes variation in plankton community composition, which is addressed in ... -
Reevaluation of design waves off the western Indian coast considering climate change
(Marine Technology Society, 2016)Knowledge of design waves with long return periods forms an essential input to many engineering applications, including structural design and analysis. Such extreme or long-term waves are conventionally evaluated using ... -
Indian Ocean dipole modulated wave climate of eastern Arabian Sea
(European Geosciences Union, 2016)Intrinsic modes of variability have a significant role in driving the climatic oscillations in the oceanic processes. In this paper, we investigate the influence of an inter-annual mode of variability, the Indian Ocean ... -
South Asian summer monsoon variability during the last ~54 kyrs inferred from surface water salinity and river run off proxies
(Elsevier, 2016)The past variability of the South Asian Monsoon is mostly known from records of wind strength over the Arabian Sea while high-resolution paleorecords from regions of strong monsoon precipitation are still lacking. Here, ... -
Why is the Bay of Bengal experiencing a reduced rate of sea surface warming?
(Royal Meteorological Society, 2016)The sea surface temperature (SST) in the Bay of Bengal (BoB) during the period 1960–1995 showed a decadal cycle, riding over a warming trend. The disruption of the decadal cycle was noticed post-1995 and was followed by a ... -
Large-scale bioprospecting of cyanobacteria, micro- and macroalgae from the Aegean Sea
(Elsevier, 2016)Marine organisms constitute approximately one-half of the total global biodiversity, being rich reservoirs of structurally diverse biofunctional components. The potential of cyanobacteria, micro- and macroalgae as sources ... -
Mud banks of Kerala: Mystery yet to be unveiled!
(CSIR-NISCAIR, 2016)Mud Banks are areas of the sea adjoining the coast with calm water during the roughest monsoon conditions of the sea. They provide a rich catch of fishery too. -
Coupled C-S-Fe geochemistry in a rapidly accumulating marine sedimentary system: Diagenetic and depositional implications
(Wiley, 2015)In the present study, we have investigated the C-S-Fe systematics in a sediment core (MD161-13) from the Krishna-Godavari (K-G) basin, Bay of Bengal he core covers the late Holocene period with high overall sedimentation ... -
Can hydrocarbons in coastal sediments be related to terrestrial flux? A case study of Godavari river discharge (Bay of Bengal)
(Current Science Association, 2015)A sediment core aged ~250 years and deposition rate of ~2.4 mm yr<sup>-1</sup> raised from the coastal region receiving inputs from the Godavari river was examined for n-alkanes The carbon preference index (CPI) of shortchain ... -
