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
(2019)This chapter reviews different mining rates for polymetallic nodules and evaluates the ensuing environmental impacts as well as metal production with respect to land reserves, metal prices, and projected investments. It ... -
Dynamics and succession of plankton communities with changing nutrient levels in tropical culture ponds of whiteleg shrimp
(2019)Optimal water quality is a prerequisite for the economic and environmental sustainability of shrimp aquaculture. The dynamics and succession of phytoplankton and microzooplankton assemblages and their interrelationship ... -
Variability of the local wave regime and the wave-induced sediment transport along the Ganpatipule coast, eastern Arabian Sea
(2019)For planning coastal protection measures, information on nearshore waves and the wave-induced sediment transport rates are required. This study examines wave-induced longshore sediment transport (LST) rate considering three ... -
Oil pollution in the Eastern Arabian Sea from invisible sources: A multi-technique approach
(2019)The Eastern Arabian Sea (EAS) is affected by oil pollution, as often evidenced by the presence of tarballs along the West Coast of India (WCI). Tarball samples collected during May 2017 along the Goa coast were subject to ... -
Experimental and Kinetic studies on the combined influence of ultrasonication and rare earths on removal of azo dyes
(2019)The aim of the present study is to decolorize azo dyes containing (-N=N-) bonds such as Reactive Black 5 (RB 5), Basic Blue 3 (BB-3) and Disperse Blue 373 (DB 373) in the presence of ultrasound (US) and rare earth (RE), ... -
Deep-Sea Mining and the Environment: An Introduction
(2019)Seafloor minerals, many of which occur in the deep ocean in international waters, have attracted significant attention due to the discovery of deposits with high metal grades and large volumes, in addition to the growth ... -
Seismic evidence of free gas migration through the gas hydrate stability zone (GHSZ) and active methane seep in Krishna-Godavari offshore basin
(2019)Seismic amplitude versus offset (AVO) analysis was performed on the multichannel seismic data in the vicinity of Site NGHP-01-10, where thick fracture-filled gas hydrate is reported, to understand the fluid migration in ... -
A global Plankton diversity monitoring program
(2019)Plankton are the base of marine food webs, essential to sustaining fisheries and other marine life. Continuous Plankton Recorders (CPRs) have sampled plankton for decades in both hemispheres and several regional seas. CPR ... -
Origin and distribution of shallow gas-charged sediment on the inner continental shelf of central west coast of India
(2019)High-resolution shallow seismic investigations on inner continental shelf of Goa have been carried out to map gas-charged sediment zones and investigate origin of trapped gas. Analyses of data reveal that the gas is trapped ... -
Conidial germination of marine-derived fungi under simulated deep-sea conditions in the presence of inducers
(2019)The abilities of conidia of four deep-sea fungi, Aspergillus flavus NIOCC20, A. sydowii CH2, A. terreus A4636 and Penicillium sp. A4623 and one terrestrial fungus, A. terreus MTCC479 to germinate under simulated deep-sea ... -
Crustal architecture and rift tectonics across the Visakhapatnam Bay basin, central-east Indian margin: Insights from multichannel seismic and potential field data
