Chilika Lake, the largest brackish water lagoon in Asia, is a prominent biodiversity hotspot along the Indian east coast. The geomorphology, water quality and biological productivity of the lake had undergone significant changes over the years under the influence of natural events and anthropogenic interventions. Decades of research have shown that the ecological changes of the lake system and its fisheries were influenced mainly by the water exchange between the lake and the sea that controls… 
Geo-Dynamics, Salinity Gradient, and Vegetation Interdependence in Chilika Lagoon, a Tropical Wetland in Eastern India
Chilika a shallow brackish lagoon, India, is shrinking for sediment surplus budget. South Mahanadi deltaic branches i.e. Daya and Bhargavi terminate at the southwest swamps of the Lagoon. The annual
Ecology, Conservation, and Restoration of Chilika Lagoon, India
This book provides an overview of the decades-long work of studying, analyzing, and reversing the environmental pressures that threatened India’s Chilika Lagoon, the largest brackish-water lagoon in
Geomorphology, Land Use/Land Cover and Sedimentary Environments of the Chilika Basin
The Chilika is one of the largest brackish water lagoons in Asia and is well known for its biologic diversity. Designated as one of the Ramsar sites in 1981, Chilika was under serious threat in the
Spatio-Temporal Variation in Physicochemical Parameters of Water in the Chilika Lagoon
Assessment of physicochemical parameters of Chilika lagoon water is of vital importance as it guides to monitor the pollution status and formulate a management plan. Mixing of water from river and
Geotechnical Characterization of Huma Bay Mud from Chilka Lake
Chilika Lake is the largest coastal lagoon in India. The geomorphology, water quality and biological productivity of the lake had undergone significant changes over the years under the influence of
Seagrass and macrophyte mediated CO2 and CH4 dynamics in shallow coastal waters
It is inferred that although seagrass meadows act as a weak source of CH4, they could be effective sinks of CO2 if land-based pollution sources are minimized.
Spatiotemporal distribution and composition of phytoplankton assemblages in a coastal tropical lagoon: Chilika, India
Based on the multivariate ordination analysis, salinity regime and light availability played important role in determining the distribution, diversity, and composition of phytoplankton communities.
Seasonal and spatial variations in elemental distributions in surface sediments of Chilika Lake in response to change in salinity and grain size distribution
Chilika lake, the largest brackish water lagoon in Asia, has a unique setting, where the north-eastern part receives freshwater from the terrestrial runoff, and the south-eastern part receives
Spatial and temporal dynamics of dissolved nutrients and factors affecting water quality of Chilika lagoon
Water quality of Chilika lagoon was assessed for pre- and post-monsoon seasons. A marked spatial and temporal variability in the water quality was observed in this study. Principal component analysis


Chilika Lagoon: Restoring ecological balance and livelihoods through re‐salinization
This paper reviews the past and present conditions and management of Chilika Lagoon, the largest lagoon on India's eastern coast. Spatial and temporal salinity gradients, because of freshwater river
Fisheries enhancement and biodiversity assessment of fish, prawn and mud crab in Chilika lagoon through hydrological intervention

Conservation of Environment and Protection of Marginalized Fishing Communities of Lake Chilika in Orissa, India
Abstract Situated in the coastal belt of Orissa in India, Lake Chilika has been designated under the Ramsar Convention as a Wetland of International importance (IUCN) especially as water fowl Habitat
A Study for the Improvement of the Chilka Lake Tidal Inlet, East Coast of India
Chilka Lake, the largest tidal inlet connected to the Bay of Bengal is hydraulically found poor with little exchange of water between the sea and the lake. The shorefront of the lake is exposed to a
