Simple multiple regression model for long range forecasting of Indian summer monsoon rainfall
(Springer-Verlag, 2008)The relationship between the Indian Ocean Sea-Surface Temperature Anomalies (SSTA) and the Indian Summer Monsoon Rainfall (ISMR) have been examined for the period, 1983-2006. High and positive correlation (0.51; significant ... -
Prediction of littoral drift with artificial neural networks
(Copernicus, 2008)The amount of sand moving parallel to a coastline forms a prerequisite for many harbor design projects. Such information is currently obtained through various empirical formulae. Despite so many works in the past an accurate ... -
The response of microzooplankton (20-200 mu m) to coastal upwelling and summer stratification in the southeastern
(Elsevier, 2008)During the late summer monsoon (LSM), coastal upwelling and river runoff have increased the nutrient concentration in the inshore region of the southeastern Arabian Sea. This has resulted in elevated chlorophyll-a (av. 40 ... -
Cytogenetic studies in green mussel, Perna viridis (Mytiloida: Pteriomorphia), from West Coast of India
(Springer-Verlag, 2008)Chromosomes of Perna viridis were characterized by karyotype analysis, C-banding and nucleolus organizer regions (NORs). The diploid chromosome number was confirmed as 30 and the karyotype is composed of ten metacentric ... -
Strong variability in bacterioplankton abundance and production in central and western Bay of Bengal
(Springer-Verlag, 2008)With large influx of freshwater that decreases sea-surface salinities, weak wind forcing of less than 10 m s sup (-1) and almost always warm (greater than 28 degrees C) sea-surface temperature that stratifies and shallows ... -
Fresh water influence on nutrient stoichiometry in a tropical estuary, Southwest coast of India
(Corvinus University of Budapest, 2008)Cochin backwaters, a micro tidal estuary, undergo a characteristic transformation from a river dominated system during summer monsoon to a tide-dominant system during pre-monsoon season. The present study observes that as ... -
Trace metal concentrations in marine zooplankton from the western Bay of Bengal
(Corvinus University of Budapest, 2008)Trace metal contents in zooplankton samples were estimated as a part of Marine Research-Living Resource Programme (MRLR) programme at 24 stations to establish the importance of these metals in the Bay of Bengal. The average ... -
Seasonal variation of oxidative biomarkers in gills and digestive gland of green-lipped mussel Perna viridis from Arabian Sea
(Elsevier, 2008)Investigations on seasonal variation in oxidative stress biomarkers were carried out on the natural population of green-lipped mussel Perna viridis collected from Bambolim beach area of Goa (India). Oxidative stress indices ... -
Degradation of alkenones by aerobic heterotrophic bacteria: Selective or not ?
(Elsevier, 2008)Four bacterial communities were isolated from Emiliania huxleyi strain TWP1 cultures before and after the algal cells had been treated with different antibiotics. Incubation of E. huxleyi with these bacterial communities ... -
Ocean iron fertilization - Moving forward in a sea of uncertainty
(American Association for the Advancement of Science, 2008)Ocean iron fertilization (OIF), one of several ocean methods proposed for mitigating rising atmospheric CO2, involves stimulating net phytoplankton growth by releasing iron to certain parts of the surface ocean. The ... -
Preface to: Marine micropaleontological studies from the northern Indian Ocean
(NISCAIR, CSIR, 2007)Indian Ocean is unique, being land-locked towards the northern margin, and experiences, highest reported oceanic productivity. It is also the locale for the most severe oxygen depleted waters in the coastal and intermediate ... -
Composition and genesis of zeolitic claystones from the central Indian Ocean Basin
(Geological Society of China, 2007)More than fifty indurated sediments recovered from the Central Indian Ocean Basin (CIoB) are examined during the course of collection for manganese nodules and crusts. The samples occur as slabs either over which ferromanganese ... -
The Mandovi and Zuari estuaries
(National Institute of Oceanography, India, 2007)Being a national institute dedicated to the study of ocean sciences, National Institute of Oceanography (NIO), Dona Paula, Goa, India owes it to the country to disseminate knowledge generated by its scientists for the ... -
Stone anchors along the coast of Chilika Lake: New light on the maritime activities of Orissa, India
(Current Science Association, 2008)Since the beginning of maritime archaeological studies, several types of stone anchors have been either retrieved or located along the coast of India. These stone anchors show their evolution to the development and have ... -
A method of transferring G.T.S. benchmark value to survey area using electronic total station
(National Institute of Oceanography, India, 2007)A G.T.S. (Great Trigonometrical Survey) benchmark is a permanently fixed reference survey station (or point), having known elevation with respect to a standard datum (mean sea level). These are established all over India ... -
Biochemical composition of the lamellibranchs Meretrix casta (Chemnitz) and Sanguinolaria diphos (Gmelin)
(Central Marine Fisheries Research Institute, 1974)The two eulamellibranch bivalves, Meretrix casta (Chemnitz) (Family: Veneridae) and Sanguinolaria diphos (Gmelin) Family: Psammobiidae) are found in vellar estuary, Porto Novo (Lat. 11 degrees 29'N and Long. 72 degrees ... -
Canonical sound speed profile and related ray acoustic parameters in the Bay of Bengal
(Andhra University, 2005)Following Munk's canonical theory, canonical parameters (i.e., B the stratification scale and epsilon the perturbation coefficient) in adiabatic ocean are obtained using SOFAR channel parameters (i.e., C sound velocity at ... -
A brief report on mets system
(National Institute of Oceanography, 2005)Mets system is basically a gas monitoring system, used for the detection of underwater gas. The system consists of a sensor, datalogger and energy module. The sensor works on the diffusion techniques. The system can be ... -
Development of summer monsoon and onset of continuous rains over central west coast of India
(Andhra University, 2005)A new interpretation of the start of summer monsoon along central west coast of India is presented in this paper. Many authors misinterpret onset of continuous rains as start of summer monsoon front, These two are different ... -
Upwelling features near Sri Lanka in the Bay of Bengal
