Physico-chemical Characteristics of Ground Water Quality in Koundampalayam Panchayat, Coimbatore District, Tamilnadu- India

Present work was undertaken to analyse the  physical and chemical characteristics of the drinking water in the selected areas of Kavundampalayam Panchayat in Coimbatore.  15 bore wells having different depth were selected for analysis (three zones with five stations each). Over all analysis explains that all the parameters showed higher values at II zone compared to other zones. Some of the parameters were found to be higher than the prescribed limits while other parameters were lower than the limits. No marked relationships were recorded among the parameters. The water quality of these zones will be degrading much in future. The major factors of the water quality deterioration appeared to be the lack of proper sanitation and protection of drinking water bodies

Data Descriptor: high resolution multibeam and hydrodynamic datasets of tidal channels and inlets of the Venice Lagoon

Tidal channels are crucial for the functioning of wetlands, though their morphological properties, which are relevant for seafloor habitats and flow, have been understudied so far. Here, we release a dataset composed of Digital Terrain Models (DTMs) extracted from a total of 2,500 linear kilometres of high-resolution multibeam echosounder (MBES) data collected in 2013 covering the entire network of tidal channels and inlets of the Venice Lagoon, Italy. The dataset comprises also the backscatter (BS) data, which reflect the acoustic properties of the seafloor, and the tidal current fields simulated by means of a high-resolution three-dimensional unstructured hydrodynamic model. The DTMs and the current fields help define how morphological and benthic properties of tidal channels are affected by the action of currents. These data are of potential broad interest not only to geomorphologists, oceanographers and ecologists studying the morphology, hydrodynamics, sediment transport and benthic habitats of tidal environments, but also to coastal engineers and stakeholders for cost-effective monitoring and sustainable management of this peculiar shallow coastal system

Bottom carbonate production in Little America Basin, Ross Sea, Antarctica

LAB samples show that the living carbonate fauna (biocoenosis) is not entirely preserved in the death assemblage (taphocoenosis) of related sediments. Although several of the collected invertebrate species produce calcareous skeletal parts, only small amounts of these skeletons are preserved as bioclasts in near surface deposits. Our collections show that less stable carbonate minerals, such as coral aragonite, are lost rapidly. Where present, the resulting biogenic carbonate sediment close to the ice-shelf is a calcitic bryomol assemblage. Such assemblage is typical of polar and cool-temperate settings

Deep-water Corallium rubrum (L., 1758) from the Mediterranean Sea: preliminary genetic characterisation.

The precious red coral Corallium rubrum (L., 1758) lives in the Mediterranean Sea and adjacent Eastern Atlantic Ocean on subtidal hard substrates. Corallium rubrum is a long-lived gorgonian coral that has been commercially harvested since ancient times for its red axial calcitic skeleton and which, at present, is thought to be in decline because of overexploitation. The depth distribution of C. rubrum is known to range from c. 15 to 300 m. Recently, live red coral colonies have been observed in the Strait of Sicily at depths of c. 600\u2013800 m. This record sheds new light on the ecology, biology, biogeography and dispersal mechanism of this species and calls for an evaluation of the genetic divergence occurring among highly fragmented populations. A genetic characterization of the deep-sea red coral colonies has been done to investigate biological processes affecting dispersal and population resilience, as well as to define the level of isolation/differentiation between shallow- and deep-water populations of the Mediterranean Sea. Deep-water C. rubrum colonies were collected at two sites (south of Malta and off Linosa Island) during the cruise MARCOS of the R/V Urania. Collected colonies were genotyped using a set of molecular markers differing in their level of polymorphism. Microsatellites have been confirmed to be useful markers for individual genotyping of C. rubrum colonies. ITS-1 and mtMSH sequences of deep-water red coral colonies were found to be different from those found in shallow water colonies, suggesting the possible occurrence of genetic isolation among shallow- and deep-water populations. These findings suggest that genetic diversity of red coral over its actual range of depth distribution is shaped by complex interactions among geological, historical, biological and ecological processes

Stratigraphic and morphologic evidence of the Holocene evolution of the Italian and Slovenian Waters (Northern Adriatic)

Il settore pi\uf9 settentrionale del Mare Adriatico, data la bassa pendenza del suo fondale, \ue8 un\u2019area particolarmente sensibile alle variazioni del livello marino che, durante il Quaternario recente, hanno causato importanti cambiamenti paleoambientali. Questa zona, situata tra l\u2019Istria, il Carso e la Pianura Veneto- Friulana, \ue8 suddivisa tra le acque territoriali italiane, slovene e croate e, nel passato, tale frammentazione amministrativa ha fortemente limitato gli studi. Nel maggio 2012 un team di ricercatori italiani e sloveni ha effettuato il rilevamento della piattaforma slovena e italiana a bordo della nave oceanografica \u201cUrania\u201d. Durante la crociera, denominata NAD2012, sono state acquisite circa 400 NM di profili sismo acustici CHIRP-sonar e, nelle acque italiane, sono stati effettuati 10 carotaggi a gravit\ue0. I nuovi dati hanno consentito di osservare in continuit\ue0 la transizione stratigrafica tra la pianura alluvionale friulana e la costa rocciosa dell\u2019Istria. L\u2019assetto generale del Nord Adriatico era stato recentemente ricostruito grazie ai dati geofisici, batimetrici e stratigrafici raccolti durante altre crociere effettuate per la realizzazione della Carta Geologica dei Mari Italiani [Trincardi et al., 2011]. Nella piattaforma slovena lo studio delle morfologie del fondale \ue8 stato consentito da un DEM di altissima risoluzione prodotto negli ultimi anni dalla societ\ue0 Harpha Sea tramite rilievi batimetrici multibeam. Il DEM ha inoltre consentito la precisa pianificazione dei profili geofisici acquisiti durante la crociera NAD2012. L\u2019area tra Monfalcone e Pirano \ue8 caratterizzata da depositi marini olocenici fini, con uno spessore massimo di 25 m presso Pirano che si assottiglia verso la costa friulana. Questo corpo sigilla la pianura alluvionale che caratterizzava la zona fino a circa 9,5 ka cal BP [Covelli et al., 2006], quando l\u2019innalzamento eustatico ha portato l\u2019Adriatico a sommergere il Golfo di Trieste. Lungo la costa orientale l\u2019antica pianura \ue8 contraddistinta da un complesso di dossi fluviali, con una direzione ENE-WSW, alimentati dalle valli che drenano il Carso e l\u2019Istria. Invece, dalla piattaforma italiana fino alla baia di Capodistria, il DEM evidenzia un percorso meandriforme inciso, parzialmente sepolto dal delta olocenico dell\u2019Isonzo e che corrisponde ad un probabile percorso tardoglaciale di questo fiume. Anche al largo di Chioggia si riconosce un esteso sistema idrografico inciso di et\ue0 post-LGM, successivamente riempito da depositi estuarini e lagunari, probabilmente formato dal Po.
