Interactions of sulfur and methane-oxidizing bacteria in tropical estuarine sediments
(2019)The bacterial oxidation of sulfur and methane is central to the biogeochemical processes in sediments such as the tropical mangrove sediments. However, there is a lacuna of information on the seasonal interactions including ... -
Genome analysis of Marinobacter phage AS1 suggests its close interactions with host Marinobacter sp.
(2019)Marinobacter comprises a widespread and ecologically significant genus of marine bacteria with vast metabolic capabilities. However, very few reports on phages infecting this genus exist. In this study, we isolated and ... -
Chromate detoxification potential of Staphylococcus sp. isolates from an estuary
(2019)Chromium (Cr) pollution is an emerging environmental problem. The present study was carried out to isolate Cr-resistant bacteria and characterize their Cr detoxification and resistance ability. Bacteria screened by exposure ... -
Spatial and temporal variations in source, diagenesis, and fate of organic matter in sediments of the Netravati River, India
(2019)Organic matter (OM) such as organic nitrogen plays a substantial role in the global biogeochemical cycling of bio-reactive components-amino acids (AA) in aquatic environments. Spatial and temporal variations in source, ... -
Seasonal variation in Beta-glucosidase-producing culturable bacterial diversity in a monsoon-influenced tropical estuary
(2019)The episodic monsoon condition in a tropical estuarine environment inputs high allochthonous materials that are rich in carbohydrates and are mainly broken down by enzymatic hydrolysis thus alter both organic matter and ... -
Environmental Factors for Design and Operation of Deep-Sea Mining System: Based on Case Studies
(2019)This chapter brings together environmental factors that are expected to influence the design and operation of deep-sea mining system for polymetallic nodules. The study analyzes possible effects of various environmental ... -
Snapshot of environmental condition in different tropical estuarine systems by using S. cucullata (an edible oyster) as bio-indicator
(2019)Accumulation of toxic metals and indigenous bacteria in oyster, (Saccostrea cucullata) and their impact on antioxidant enzyme activities in the biological system was studied and used to provide snapshot of environmental ... -
Extinction of Antimicrobial Resistant Pathogens Using Silver Embedded Silica Nanoparticles and an Efflux Pump Blocker
(2019)Control measures against antimicrobial resistant bacterial pathogens are important challenges in our daily life. In this study, we discuss the sensitivity and resistance of four bacterial pathogens, Vibrio alginolyticus, ... -
Processes controlling arsenic enrichment along the eastern Arabian Sea surficial sediments
(2019)The processes enriching redox-sensitive arsenic (As) was investigated in 111 surficial sediments (27-3679�m water depth) overlain by varying levels of dissolved oxygen along the eastern Arabian Sea. Under oxygenated ... -
Isotopic fingerprinting of fluid circulation at the terminal stage of the Himalayan orogeny: An example from the Himalayan forearc basin, Indus Tsangpo suture zone, Ladakh, India
(2019)Quartz and calcite veins are omnipresent in the Indus basin sedimentary rocks (IBSRs) of the Indus Tsangpo suture zone (ITSZ) which were formed by the accumulation of sediments derived from both sides of the tectonic plate. ... -
Colonies of marine cyanobacteria Trichodesmium interact with associated bacteria to acquire iron from dust
(2019)Iron (Fe) bioavailability limits phytoplankton growth in vast ocean regions. Iron-rich dust uplifted from deserts is transported in the atmosphere and deposited on the ocean surface. However, this dust is a poor source of ... -
Report of epibiont ciliates (Cilliophora: Suctorea) on pelagic ostracods (Crustacea: Ostracoda) from the Arabian Sea
(2019)The article deals with the report of 5 suctorians viz. Lecanophryella satyanandani (Santhakumari, 1986), Paracineta karunakarani Santhakumari, 1986, Ephelota gemmipara (Hertwig, 1876), Acineta foetida Maupas, 1881 and ... -
Indonesian throughflow controlled the westward extent of the Indo-Pacific Warm Pool during glacial-interglacial intervals
(2019)The tropical atmospheric circulation is strongly influenced by the sea surface temperature (SST) of the warmest region of the world ocean, the Indo-Pacific Warm Pool (IPWP). The effect of recent anomalous Indian Ocean ... -
sFDvent: A global trait database for deep-sea hydrothermal-vent fauna
(2019)Traits are increasingly being used to quantify global biodiversity patterns, with trait databases growing in size and number, across diverse taxa. Despite growing interest in a trait?based approach to the biodiversity of ... -
Last 35,000-year water column temperature and productivity variation in the Eastern Arabian Sea: monsoon and global climate connection
(2019)A radiocarbon-dated sediment core from the flat top of Wadia Guyot at a 1500-m water depth in the Eastern Arabian Sea (EAS), western margin of India, preserves the records of past changes in water column temperatures and ... -
Macrobenthic fauna with special reference to the ecology and population structure of a tubicolous amphipod, Chelicorophium madrasensis (Nayar, 1950) in a tropical estuary, southwest coast of India
(2019)The ecology and population structure of the corophid amphipod Chelicorophium madrasensis (Nayar, 1950) was studied for 1�year in the Cochin estuary (CE), a tropical monsoonal estuary along the southwest coast of India. The ... -
Shipwrecks in the off shore waters of the Indian peninsula-a review
(2019)Marine archaeological investigations in the Indian waters have made steady progress during the last four decades, spearheaded by the marine archaeology centre of the CSIR-NIO, Dona Paula, Goa. Wooden and steel hulled ... -
Review of Mining Rates, Environmental Impacts, Metal Values, and Investments for Polymetallic Nodule Mining
