A non-diatom plankton bloom controlled by copepod grazing and amphipod predation: Preliminary results from the LOHAFEX iron-fertilisation experiment
(GLOBEC, 2009)The most memorable LOHAFEX cruise came to an end on 17 March 2009 when RV Polarstern docked in the harbour of Punta Arenas (southern Chile) after successfully carrying out the longest iron fertilisation experiment so far ... -
Distribution of butyltins (TBT, DBT, MBT) in sediments of Gulf of Cadiz (Spain) and its bioaccumulation in the clam Ruditapes philippinarum
(Springer, 2009)Surface sediment samples were analyzed for organotins namely tributyltin (TBT), dibutyltin and monobutyltin from six areas located in the Gulf of Cadiz (14 stations), Spain. The total butyltin ranged between undetected and ... -
Analysis of timber and coating material on an iron anchor recovered off Aguada Bay, Goa
(Current Science Association, 2009)Distinct developments have been observed in the evolution of stone and iron anchors. A wide variety of stone anchors have been reported from Indian waters, preceding the introduction of iron anchors by the Europeans. ... -
Trace gases and CO sub(2) isotope records from Cabo de Rama, India
(Current Science Association, 2009)Concentrations of carbon dioxide (CO sub(2)), methane (CH sub(4)), carbon monoxide (CO), nitrous oxide (N sub(2) O) and hydrogen (H sub(2)), and the stable carbon (delta sup(13) C- CO sub(2)) and oxygen ( delta sup(18) O ... -
A study on biochemical changes in the penaeid shrimp, Metapenaeus monoceros (Fabricius) following exposure to sublethal doses of organochlorine pesticide (endosulfan)
(Elsevier, 2009)Endosulfan, a broad-spectrum non-systemic organochlorine (OC) pesticide is extensively used to control a wide variety of pests in agriculture, horticulture and public health programmes. Biochemical changes occurring in the ... -

On the diurnal ranges of sea surface temperature (SST) in the north Indian Ocean
(Indian Academy of Sciences, 2009)This paper describes the variability in the diurnal range of SST in the north Indian Ocean using in situ measurements and tests the suitability of simple regression models in estimating the diurnal range. SST measurements ... -
Abundance and production of particle-associated bacteria and their role in a mangrove-dominated estuary
(Inter-Research, 2009)A 1 yr study was carried out in the mangrove-dominated, tropical Mandovi estuary (Goa, India) to assess the contribution of particle-associated bacteria (PAB) to the system’s variability in terms of abundance and productivity. ... -
Rock physics modeling of shallow marine sediments in the eastern continental margin of India
(The International Society of Offshore and Polar Engineers, 2009)Rock physics models are used to estimate the geo-technical properties such as the elastic moduli from the porosity and mineralogy datasets. If the velocity measurement is available the same rock physics model can be used ... -
Oxygen isotope records of Globigerina bulloides across a north-south transect in the south-western Indian Ocean
(Springer, 2009)Along a north-south transect (9.69 degrees N to 55.01 degrees S) in the southwestern Indian Ocean during the Indian Pilot Expedition to Southern Ocean (PESO), the oxygen isotopic analysis of planktic foraminifera (Globigerina ... -
The fine art of aquascaping
(Dixitulu, J.V.H., 2009)The ornamental fish trade plays a significant role in the economics of developed as well as developing countries not only as a foreign exchange earner but also as a source of employment. Global trade in ornamental fish ... -
Diagenesis and bioavailability of mercury in the contaminated sediments of Ulhas Estuary, India
(Elsevier, 2009)Sequential extraction of Hg was performed in a core collected from intertidal area in Ulhas Estuary in order to characterize the downward distribution and diagenetic behavior of Hg in a polluted estuary. Concentration of ... -
Acoustic characterization of seafloor sediment employing a hybrid method of neural network architecture and fuzzy algorithm
(IEEE, 2009)Seafloor sediment is characterized acoustically in the western continental shelf of India using the echo features extracted from normal incidence single-beam echo sounder backscatter returns at 33 and 210 kHz. The seafloor ... -
Evidences for seawater-rock hydrothermal interaction in the serpentinites from Northern Central Indian Ridge
(Current Science Association, 2009)Serpentinites and serpentinized harzburgites were collected from a ridge-transform intersection at 6 ddgrees 39 minutes S-68 degrees 19 minutes E from the Northern Central Indian Ridge. The degree of serpentinization is ... -
New records of Thecacineta cothurnioides and Trematosoma rotunda (Ciliophora, Suctorea) as epibionts on nematodes from the Indian Ocean
(Not clear, 2009)This article deals with the report of two suctorian ciliates species viz. Thecacineta cothurnioides Collin, 1909 and Trematosoma rotunda (Allgen, 1952) as epibionts on Tricoma sp. and Pseudochromadora sp. (Nematoda) ... -
Shallow gas charged sediments off the Indian west coast: Genesis and distribution
(Elsevier, 2009)Geophysical and geochemical surveys were carried out off Goa, central west coast of India, to understand the genesis and distribution of shallow gases in marine sediments. Shallow gas charged sediments within the water ... -
Effects of sudden stress due to heavy metal mercury on benthic foraminifer Rosalina leei: Laboratory culture experiment
