water samples were collected from five selected mangrove ecosystems along kerala coast, north of cochin, on seasonal basis and analysed for various hydrographic parameters. to explain spatiotemporalvariations and the processes controlling their distribution, anova (two factor without replication),correlation and principal component analysis were carried out. concentration of total nitrogen vari...

Surface samples have been collected from Kerala coast, Valapatanam-Azhikode deposit of northern Kerala coast. The average heavy minerals percentage shows 30.32 %. The heavy mineral assemblage of samples from area showed an appreciable percentage of opaque followed by sillimanite and zircon.

Among radiation exposure pathways to human beings, inhalation dose is the most prominent one. Radon, thoron, and their progeny contribute more than 50 per cent to the annual effective dose due to natural radioactivity. South west coast of India is classified as a High Natural Background Radioactivity Area and large scale data on natural radioactivity and dosimetry are available from these coast...

Silver pomfret, Pampus argenteus is an economically important seafood species. The fishery resource of pomfret in Indian waters shows a dwindling catch since the last few years and the pomfrets caught were mostly undersized which calls for immediate attempts for management of resources. An accurate definition of population structure is important for management of this species. The genetic stock...

Kerala, the South-West coastal state of India, was ravaged by a series floods during Monsoon 2018. The season marked severely anomalous rainfall trends, with over 100 mm departures from mean daily precipitation in northern districts State. Unlike previous works, this study not only documents extreme event, but also identifies tropical dynamics responsible for it. synoptic disturbances Pacific t...

The temperature and moisture data from TIROS operational vertical sounder (TOVS) are examined to obtain humidity parameters like, mid and upper tropospheric water vapour, and scale height of water vapour. Their usefulness in characterizing the onset of south-west (SW) monsoon over India is studied. The NOAA satellite data (finished product) with a resolution of 2.5 ~ lat/lon are used to obtain ...

The prevalence of ailments and hospitalization in Kerala was examined using data from the 52 nd National Sample Survey Data on Health Care in Kerala in 1995-6. The survey included 24401 people from 4928 households. Age and seasonality had considerable effects on the morbidity of individuals. The burden of ill health was higher in rural areas than in urban areas. People who were more likely to h...
