The present study examines the seasonal relationship between land surface temperature (LST) and normalized difference water index (NDWI) on various surfaces in Raipur City of India by using a series Landsat images for four specific seasons since 1991-92. LST is retrieved mono-window algorithm technique. results show that area noticeably affected composition. best correlation (correlation coeffi...

Seasonal variations in the fouling diatom community from a monsoon influenced tropical estuary were investigated. The community composition did not differ significantly between stainless steel and polystyrene substrata due to dominance by Navicula spp. The experimental evidence suggests that Amphora, which is a dominant fouling diatom in temperate waters, ultimately dominates the community in t...

Incidence of faecal coliforms in shellfish harvesting areas of the southern coastal district of Karnataka was examined for evaluating the sanitary quality in relation to the seasonal monsoon and river-runoff. Faecal coliforms (FC) counts in seawater, mussel tissue and sediments were highest in monsoon. Geometric mean for FC in sea water was below 14 MPN/100 ml, standard set for “approved area” ...

The Barind region of Bangladesh suffers from frequent drought due to poor and delayed rainfall in pre monsoon and monsoon season. In the present study details analysis of rainfall data has been carried out for the years 1971-2010. Two well known drought indices, Standard precipitation index (SPI) has been used to evaluate the precipitation deficit, and Markov chain model used to quantify the dr...

Trichiurus lepturus (ribbon fish) was collected from different spatial locations (south west (SW) coast edging the Arabian Sea and south east (SE) coast surrounding the Bay of Bengal of India) and seasons (pre-monsoon, monsoon and post-monsoon) during a continuous period of four years (2008 through 2011), and their edible muscles were studied for differential nutritional compositions of protein...

Abstract Pakistan is an agricultural country mainly dependant on irrigation through the Indus water system. The country has developed the world’s largest contagious canal network. Monsoon precipitation is the lifeline of Pakistan which not only caters the national power supply and standing crops water demands but help gathers the reserves to meet the requirements of low flow period in the next ...

The present study is aimed at characterizing the landfill leachate as well as its impact on the surrounding groundwater in Kolkata, India. Landfill leachate has been seasonally characterized from 2012-2014, indicating the landfill site in methanogenic phase with high contamination of organics, nutrients, salts, and heavy metals. Sixty groundwater samples have been analyzed for twenty two physic...

Vegetative plants of certain seaweeds were collected from the natural habitat of Kilakarai and Mandapam coast were subjected to SEM-energy dispersive spectroscopic analysis and quantified the following minerals viz., Na, Mg, Si, S, Cl, K, Ca, Mn, P, Fe, Zn and Cr during summer, pre-monsoon, monsoon and post-monsoon seasons in 2007-2008. The order of preferential accumulation of elemental compos...
