Numerical modelling of tides and storm surges in the Bay of Bengal
(2012)This study generated improved reliable bathymetric datasets for the continental shelf of the Indian Ocean. Simulation of tides and generation of co-range and co-tidal charts of the major semi-diurnal and diurnal constituents ... -
Ancient coastal transportation system along the Western Saurashtra coast: Evidence from Navibandar
(Current Science Association, 2013)A recent maritime archaeological exploration around Navibandar, Gujarat yielded evidence of ferry/jetty points. These points were well connected with the stone-paved roads. Interestingly, the roads have evidence of the use ... -
Impact of eutrophication on the occurrence of Trichodesmium in the Cochin backwaters, the largest estuary along the west coast of India
(Springer, 2013)Phytoplankton studies in early 1970s have shown the annual dominance of diatoms and a seasonal abundance of Trichodesmium in the lower reaches of the Cochin backwaters (CBW) and adjacent coastal Arabian Sea during the ... -
Nutrient biogeochemistry of the eastern Arabian Sea during the southwest monsoon retreat
(Springer, 2013)Hydrography of the eastern Arabian Sea and associated chemical and biological responses were studied during the withdrawal phase of summer monsoon 2003. The shelf region off the southwest coast of India (10 degrees N-15 ... -
Changes in the soft-bottom macrobenthic diversity and community structure from the ports of Mumbai, India
(Springer, 2013)Soft-bottom macrobenthic diversity and community structure were assessed at Mumbai and Jawaharlal Nehru ports during three different periods between 2001 and 2002 (November 2001 post-monsoon 1, April/May 2002 pre-monsoon, ... -
New records of epibiont Ciliates (Ciliophora) from Indian coast with descriptions of six new species
(Station Biologique de Roscoff, 2013)Six epibiont ciliates Cothurnia palkensis, C. nova, C. disper, C. dovgali, C. mannaerensis and C. clampi are described as new for science from the Indian coast. Acineta truncata Collin, 1909 and A. tuberosa Ehrenberg, 1834 ... -
Assessing the distribution and abundance of seabed minerals from seafloor photographic data in the Central Indian Ocean Basin
(Taylor & Francis, 2013)Distribution characteristics of deep-sea mineral resources such as polymetallic nodules and ferromanganese crusts are often influenced by local seafloor features such as the topographic undulations and sediment thickness. ... -
Dinoflagellate cyst assemblages in recent sediments of Visakhapatnam harbour, east coast of India: Influence of environmental characteristics
(Elsevier, 2013)The distribution and abundance of dinoflagellate cysts in recent sediments from Visakhapatnam harbour, east coast of India was investigated and compared with sediment characteristics and physico-chemical variables of the ... -
Seasonal stratification and property distributions in a tropical estuary (Cochin estuary, west coast, India)
(European Geosciences Union, 2013)The intratidal, spring–neap and seasonal variations in stratification were examined in the Cochin estuary. The observations established a strong connection with the distribution of chemical and biological properties. The ... -
Ecology and trophic preference of picoplankton and nanoplankton in the Gulf of Mannar and the Palk Bay, southeast coast of India
(Elsevier, 2013)The Gulf of Mannar (GoM) and the Palk Bay (PB) are two least studied marine environments located between India and Sri Lanka. The environmental and smaller plankton (0.2–20 mu m) data from 30 locations in the GoM and PB ... -
Macrobenthos in anthropogenically influenced zones of a coralline marine protected area in the Gulf of Kachchh, India
(Elsevier, 2013)The Gulf of Kachchh Marine National Park and Sanctuary (MNPS) has one of the four coral reef systems of India. However, owing to its unique geographical position, this area has been transformed into an industrial hub ... -
A study on the characteristics of temperature inversions in active and break phases of Indian summer monsoon
(Elsevier, 2013)The thermal inversion characteristics during active and break cycles of two consecutive and contrasting monsoon years were studied using GPS radiosonde profiles in Goa (15 degrees 46′ N; 73 degrees 08′ E), located on the ... -
Ultrafiltration technique in conjunction with competing ligand exchange method for Ni–humics speciation in aquatic environment
(Elsevier, 2013)The combination of ultrafiltration technique with competing ligand exchange method provides a better understanding of interactions between Ni and different molecular weight fractions of humic acid (HA) at varying pH in ... -
Ichthyofaunal diversity and ecology of intertidal rock pools of Goa, west coast of India
(Fishing Chimes, 2012)A total of 386 fish representing 9 species were collected from two rocky shores of Goa viz. Vainguinim and Anjuna beaches. Family Blenniidae constituted 80% of fishes which included three species of the Genus Istiblennies ... -
Abundance and size variation of Globorotalia menardii in the Northeastern Indian Ocean during the Late Quaternary
(Geological Society of India, 2012)Variation in absolute abundance, size and coiling direction ratio of the planktic foraminifera Globorotalia menardii during the late Quaternary have been studied in three cores, collected along a north-south transect from ... -
Influence of upper-ocean stratification on tropical cyclone-induced surface cooling in the Bay of Bengal
(American Geophysical Union, 2012)Surface cooling induced by tropical cyclones (TCs) is about three times larger during premonsoon than during postmonsoon season in the Bay of Bengal. We investigate processes responsible for this seasonal contrast using ... -
Microbial community response during the iron fertilization experiment LOHAFEX
(American Society for Microbiology, 2012)Iron fertilization experiments in high nutrient-low chlorophyll areas are known to induce phytoplankton blooms. However, little is known about the response of the microbial community upon iron fertilization. As part of the ... -
Controlling factors of the oxygen balance in the Arabian Sea's OMZ
(European Geosciences Union, 2012)The expansion of OMZs (oxygen minimum zones) due to climate change and their possible evolution and impacts on the ecosystems and the atmosphere are still debated, mostly because of the inability of global climate models ... -
