Viruses are recognized as the most abundant and dynamic biological entities in the marine and estuarine environment. However, studies on the dynamics and activity of viruses in transient estuarine systems are limited. This study examines temporal and spatial variations in viral abundance (VA) and viral activity across the salinity gradient in a monsoon-driven tropical estuarine system (Cochin e...

Coastal environment is controlled by a complex interaction of physical, chemical, biological, and geological processes. Physical processes are responsible for controlling the transport and distribution of all dissolved and suspended matters in coastal waters. A comprehensive understanding of these processes is crucial to the design and implementation of management strategies that track ecosyste...

Physicochemical variability in estuarine systems plays an important role in estuarine processes and in the lifecycles of estuarine organisms. In particular, seasonality of freshwater inflow to estuaries may be important in various aspects of fish lifecycles. This study aimed to further understand these relationships by studying the movements of a top-level estuarine predator in response to phys...

a comprehensive evaluation of the residual levels of organochlorine insecticides (ocis) in the sediment cores of cochin estuarine system (ces) is highlighted in this research article. it assessed the distribution pattern and impact of these xenobiotics in this environmental niche. fifteen persistent organochlorine compounds (ocs) were quantitatively analysed in the six sediment core samples col...

phytoplankton communities play a significant role in the oceanic biological pump by forming the base of the trophic structure. increase in nutrients loading affects spatial and temporal distribution of phytoplankton. this study examined the phytoplankton community structure and ecological indices in relation to nutrients dynamics in both estuarine and oceanic areas of ramisi-vanga systems alon...

Satellite measurements of coastal and estuarine water level, water temperature, salinity, and turbidity continue to improve and now provide an opportunity to interpret coastal processes over an unprecedented range of spatial scales. Because these measurements are surface manifestations of tidal processes, river flow, and bathymetry, they can be used to obtain information about underlying physic...

Tidal inlets are of great societal importance as they are often associated with ports and harbours, industry, tourism, recreation and prime waterfront real estate. Their behaviour is governed by the delicate balance of oceanic processes (tides, waves and mean sea level), and fluvial/estuarine processes (riverflow and heat fluxes), all of which can be significantly affected by climate change (CC...

In many European estuaries, extensive areas of intertidal habitats consist of bare mudflats and sandflats that harbour a very high abundance and biomass of macrobenthic invertebrates. The high stocks of macrobenthos in turn provide important food sources for the higher trophic levels such as fish and shorebirds. Climate change and associated sea-level rise will have potential to cause changes i...
