Pulicat Lake is one of the major wetlands in India. It is the second largest brackish water lagoon in India next to Chilika Lake in Orissa state. Pulicat Lake sits beside the Bay of Bengal so, the study on the mouth is vital. The investigations were carried out by using multi-temporal satellite imageries of IRS P6, LISS III data for four years viz., 2009, 2011, 2012 and 2013. Subsequent changes in the width of the lake at the southern side were measured. It is found that the lake mouth is not static but dynamic predominantly fluctuating year by year. Obviously, this poses threat to the lake biodiversity. Hence, it is high time to mitigate, manage, monitor and protect the existing width of the sea mouth to keep the lake biological, ecological, economically active. This paper noticed a considerable change in the mouth of the lake studied using satellite imageries and socio-economic settings

“…The rainfall occurs from late August (SWM) to early November (NEM) in the Nellore region. The average annual rainfall in the coastal regions in the Nellore district decreases from 1,270 to 762 mm from the eastern to the western extremity of the basin, respectively (Sreenivasulu et al, 2016). The atmospheric temperature (AT) ranged from 29.7 to 40.9 • C in the summer, and it varied from 21.4 to 29.3 • C in the winter.…”

“…Previous scientific records on the seawater quality parameters are minimal in this region. Although a few environmental contamination studies have been carried out on metal pollution (foraminifera, seawater, sediment, bivalves, and benthos) in this area (Sundara Raja Reddy et al, 2016;Patel et al, 2018;Jha et al, 2019;Pandey et al, 2021), long-term studies on the physicochemical parameters are sparse (Sreenivasulu et al, 2016).…”

Evaluation of Physicochemical Characteristics of Coastal Waters of Nellore, Southeast Coast of India, by a Multivariate Statistical Approach

et al. 2022

The Swarnamukhi river estuary (SRE), and the surrounding sea in Nellore, southeast coast of India, is one of the least studied marine environments, notably for physicochemical characteristics. Seawater samples were collected from five stations every month from 2014 to 2017 to assess physicochemical characteristics. The open sea (OS) station was significantly different from the inner stations, according to non-metric multidimensional scaling and cluster analysis. The variability was shown by strong factor loadings of atmospheric temperature (0.87), water temperature (0.84), biochemical oxygen demand (0.77), ammonia (0.85), and total nitrogen (0.78). Furthermore, one-way ANOVA and box-whisker plots facilitated simplifying and corroborating multivariate results that showed high concentration in the inner stations. Based on the N/P and Si/N ratios, nitrate and silicate were the key limiting factors in this study. The findings are critical for establishing reference conditions for comparison studies with other comparable ecosystems in the tropical region for better environmental conservation and management.

“…Coastal morpho-dynamics are the marine, physical, meteorological and biological activities that interact with the sediments to produce a particular coastal environmental setting (Short & Jackson, 2013). The waves and currents play a significant role in controlling sediment migration and deposition (Sreenivasulu et al, 2016). Wind-generated wave energy input into the littoral zone and, together with wave-generated currents are responsible for the alteration of coastal morphology.…”

Landsat 8 OLI/TIRS data of Tupilipalem coast demonstrations the periodic closure of lagoon mouth over a brief period affecting the ecological setting and the faunal diversity and distribution. The coastal ecosystem includes a significant metal pollutant due to anthropogenic activities. This study documents forty-nine numbers of benthic foraminiferal species and establishes its relationship with heavy metal concentrations (Fe, Mn, Cr, Cu, Ni, Pb, Zn and Cd). The factor loading matrix generated using factor analysis grades the positive and negative correlations among the heavy metals species. The results of geoaccumulation index, enrichment factor, and pollution load index, construes the seasonal differences in metal concentrations and prevalence of higher concentrations of metals in the sediments. Besides, this paper discusses the impact of coastal morphology on heavy metal concentrations coupled with ecology and distribution of benthic foraminifera.
