The beach sediments are medium-sized sand, unimodal, well-sorted to mode-rately sorted, nearly symmetrical and mesokurtic to leptokurtic in terms of their grain size distribution. The sand-silt ratios are very high. The content of heavy minerals is very less compared to the content of light minerals and there is an appreciable percentage of shell fragments. The heavy minerals commonly found in these sediments in the decreasing order of abundance are opaques, garnet, zircon, hornblende, actinolitetremolite, sillimanite, enstatite, rutile, pyroxene, spinel, epidote and kyanite. The percentage of quartz in the light mineral fraction varies from 68 to 99. The provenance of these beach sands is the Netravati river basin of Western Ghats largely consisting of Precambrian granitic gneisses.Keywords

This review is based on a comprehensive search of literature on beach morphological and nearshore dynamics studies in India. It includes importance of beach morphological studies, critical evaluation of various methods/approaches and tools used, sediment dynamics and causes for coastal erosion, coastal protection structures and their impact on beach morphology and shoreline changes. The objectives of this paper are to (1) review the State-of-the-Art of research conducted and inferences drawn in the country on beach morphology, (2) understand the impact of coastal structures (seawalls and breakwaters) on beach morphology and shoreline changes, and (3) to identify the grey areas in beach morphotogical studies and suggest the approaches for future research or field monitoring programs.Keywords

The Fourth Conference of Karnataka Science and Technology Academy (KSTA) was organised at Mangalore University on 28th and 29th January, 2012. The Hon’ble Chief Minister of Karnataka, Shri D.V. Sadananda Gowda inaugurated the conference as well as science exhibition. In his inaugural address, the Chief Minister urged the scientific community to pursue the challenges and convert the challenges into opportunities in the present competitive world. He mentioned challenges that the state is facing, especially in drought management, dry land development and resource conservation. Furthermore, he stressed the need of effective utilization of available water resources for agriculture as well as storage and processing of agricultural products. He said that only a quarter of the agricultural land in the state is irrigated and hence it is necessary to develop drought resistant variety of crops for dry land cultivation. He exhorted scientific fraternity to come up with tangible solutions to the challenges in the field of marine fisheries management, solid waste management, renewable energy and climate change. He concluded his speech by announcing special fellowship scheme to encourage students who opt for basic science subjects at degree, PG and doctoral levels.- National Seminar on Geospatial and Ecological Mapping of Biodiversity: Tools and Techniques

This article highlights major scientific outcomes of the studies carried out using Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) airborne data over the coastal regions of Mangaluru, Gulf of Kachchh (GoK) and Chilika lagoon. Various hyperspectral remote sensing techniques involving bio-optical models and spectral classification algorithms are used to achieve different objectives related to coastal ecosystem monitoring. AVIRIS-NG airborne data are used to estimate particle size of suspended solids along the coastal waters of Mangaluru using an analytical optical model. The spatial distribution of particle size of the suspended solids in the coastal waters is brought out, while along the coastal land of Mangaluru, the beaches are classified based on uniform sediment characteristics using spectral matching algorithm. AVIRIS-NG data for Pirotan reef in GoK is analysed and species-level identification of the dominant brown macroalgae is carried out. Species-level distribution of brown macroalgae is mapped and used to study the microhabitat preference of different species. At Chilika lagoon, the AVIRIS-NG data are analysed to map the abundance of submerged seagrass using bio-optical model, which provides vital information to the coastal management community. The study asserts the importance of hyperspectral data and various advanced data analysis techniques related to the estimation of geophysical parameters of the coastal waters and monitoring the vital coastal ecosystems.Keywords
