Organic carbon and humic acids in sediments of the Arabian Sea and factors governing their distribution
Organic carbon and humic acids in the sediments of the Arabian Sea show distinct regional variations to the south and north of 15~'N latitude. Significant variations are also observed from the shelf to the slope regions. ...
Grain size studies on the nearshore sediments of Jaigad, Ambwah and Varvada Bays, Maharashtra
(Geological Society of India, 1997)
Bivariate plots of the textural parameter data suggest overlapping environments, such as river/beach to JB, beach/dune/river to AB and dune/beach to VB sediments.
Monitoring effects of simulated disturbance at INDEX site: Current status and future activities
(International Society of Offshore and Polar Engineers, 2003)
During the Indian Deep-Sea Environment Experiment (INDEX), greater than 6000 cu.m of sediment was resuspended 5 m above seafloor. Data collected from deep-towed photography, sediment traps, sediment coring and CTD operations ...
Ferromanganese nodules and their associated sediments from the Central Indian Ocean Basin: Rare earth element geochemistry
(Taylor and Francis, 2001)
The rare earth element (REE) distribution in nine deep-sea ferromanganese nodules and their associated siliceous sediments from the Central Indian Ocean Basin (CIOB) have been studied to elucidate the REE relationship among ...
Acoustic seafloor sediment classification using self-organizing feature maps
A self-organizing feature map (SOFM), a kind of artificial neural network (ANN) architecture, is used in this work for continental shelf seafloor sediment classification. Echo data are acquired using an echosounding system ...
Tracking the history of dinoflagellate cyst assemblages in sediments from the west coast of India
In order to trace the history of dinoflagellate cyst assemblages and provide new insights in to Harmful Algal Bloom (HAB) dynamics in monsoon influenced tropical environments, sediment cores were collected from four different ...
Geochemical and isotopic signatures of surficial sediments from the western continental shelf of India: Inferring provenance, weathering, and the nature of organic matter
(Society for Sedimentary Geology, 2013)
Bottom sediments from thirteen transects sampled mainly at depth contours of 30, 100, and 200 m along the western continental margin of India, falling in two offshore sectors from Dwaraka to Goa and Cape Comorin to Goa, ...
Estimation of carbonate concentration and characterization of marine sediments by Fourier transform infrared spectroscopy.
Fourier Transform Infrared Spectroscopy (FTIR) is a well established method for the characterization of mineralogical and geochemical properties of marine sediments. Understanding the biogeochemical changes in marine ...
Seabottom backscatter studies in the western continental shelf of India
(Academic Press, 1999)
The study is initiated to observe the interaction effects of the sound signal with three different sediment bottoms in the shelf area between Cochin and Mangalore in the western continental shelf of India. An echo signal ...
Studies on sup(226) Ra and sup(210) Pb activities and the concentration factors of sup(226) Ra in the surface organic layers of the estuarine sediments of Mindola and Purna rivers in India
The sediment samples have been collected from estuarine regions of Mindola and Purna of Gujarat State These samples are found to contain less than 3% of organic matter which scavenge and carry most of the activity of ...
