Journal ArticleDOI
Distribution and sources of sedimentary organic matter in a tropical estuary, south west coast of India (Cochin estuary): a baseline study.
TL;DR: It is found that the dynamic cycling of nitrogen through various biogeochemical and organic matter degradation processes modifies the OC/TN ratios and δ¹⁵N to a considerable degree.
Journal ArticleDOI
Toxic Metals Enrichment in the Surficial Sediments of a Eutrophic Tropical Estuary (Cochin Backwaters, Southwest Coast of India)
TL;DR: Concentrations and distributions of trace metals in surficial sediments of the Cochin backwaters were studied during both monsoon and pre-monsoon periods and showed that metal contamination was the product of anthropogenic activities.
Journal ArticleDOI
Dynamics of polycyclic aromatic hydrocarbons (PAHs) in surface sediments of Cochin estuary, India
A. Ramzi,K. Habeeb Rahman,T.R. Gireeshkumar,K.K. Balachandran,Chacko Jacob,N. Chandramohanakumar +5 more
TL;DR: Polycyclic aromatic hydrocarbons showed significant seasonal dynamics in surface sediments of a tropical ecosystem (Cochin estuary, south west coast of India), indicating land/river runoff as the major transport pathway.
Journal ArticleDOI
Spatial variability and contamination of heavy metals in the inter-tidal systems of a tropical environment
C. S. Ratheesh Kumar,Manju Mary Joseph,T. R. Gireesh Kumar,K. R. Renjith,M.N. Manju,N. Chandramohanakumar +5 more
TL;DR: In this article, the degree of anthropogenic influence on heavy metal concentration in the sediments of the mangrove and adjacent estuarine stations using enrichment factor and geoaccumulation index was assessed.

Georg Martin,Georg Martin,K. R. Muraleedharan,J.G. Vijay,G. Rejomon,N.V. Madhu,A. Shivaprasad,C K Haridevi,M. Nair,K.K. Balachandran,C. Revichandran,K. V. Jayalakshmy,N. Chandramohanakumar +12 more
TL;DR: In this paper, the authors studied the hydrographic characteristics of the southwest coast of India and its adjoining Cochin backwaters (CBW) during the summer monsoon period and observed anomalous formation of anoxia and denitrification were observed in the bottom layers of CBW, which have not been previously reported elsewhere in any tropical estuarine systems.
