Phytoplankton response to the contrasting physical regimes in the eastern Arabian Sea during north east monsoon

Chndrasekhararao, A.V.; Kurian, S.; Vidya, P.J.; Gauns, M.; Shenoy, D.M.; Mulla, A.; Naik, H.; Reddy, T.V.; Naqvi, S.W.A. (Elsevier, 2018)

Phytoplankton abundance and composition in two contrasting physical regimes - convective mixing in the northeastern Arabian Sea (NEAS) and Arabian Sea mini warm pool (ASMWP) in the southeastern Arabian Sea (SEAS) - were ...

Epibiotic communities (microalgae and meiofauna) on the pneumatophores of Avicennia officinalis (L.)

Sahoo, G.; Ansari, Z.A.; Shaikh, J.B.; Varik, S.U.; Gauns, M. (Elsevier, 2018)

In a mangrove environment, several groups of organisms are symbiotically associated with pneumatophores (aerial roots). But whether these organisms are exclusively found in this habitat (uniqueness) or accidentally settled ...

Meta-analysis cum machine learning approaches address the structure and biogeochemical potential of marine copepod associated bacteriobiomes

Sadaiappan, B.; PrasannaKumar, C.; Nambiar, V.U.; Subramanian, M.; Gauns, M. (Springer-Nature, 2021)

Copepods are the dominant members of the zooplankton community and the most abundant form of life. It is imperative to obtain insights into the copepod-associated bacteriobiomes (CAB) in order to identify specific bacterial ...

Environmental association of heterotrophic micro-eukaryotes in the varying biogeochemical regimes of the Arabian Sea, resolved via high-throughput sequencing

Das, P.B.; Gauns, M.; Stock, A.; Naqvi, S.W.A. (Springer, 2021)

The diverse physicochemical conditions prevailing in the Arabian Sea are expected to result in marked spatial variations in heterotrophic flagellate (HF) and ciliate communities. Here, we report the environmental association ...

Benthic exchange along a tropical estuarine salinity gradient during dry season: Biogeochemical and ecological implications

Pratihary, A.K.; Naik, Richita; Karapurkar, S.; Gauthankar, M.; Khandeparker, R.; Manjrekar, S.; Gauns, M. (Elsevier, 2021)

Benthic biogeochemistry and its coupling with pelagic ecology are less understood in tropical than in temperate estuaries, which have significant implications for global carbon and nutrient cycling. In dry season, the ...

Diversity of culturable nitrate-reducing bacteria from the Arabian Sea oxygen minimum zone

Mulla, A.; Fernandes, G.; Menezes, L.; Meena, R.M.; Naik, H.; Gauns, M.; Damare, S.R. (Elsevier, 2018)

The subsurface waters of the northern Arabian Sea display a pronounced oxygen minimum layer associated with high nitrite maxima which provide an ideal niche for organisms that can respire nitrate. Culture-based studies ...

A study on microzooplankton community from the coastal waters of eastern Arabian Sea: Emphasis on the dominance of heterotrophic dinoflagellates

Elangovan, S.S.; Gauns, M. (Springer, 2023)

We studied the community composition of microzooplankton (MZP) from the surface waters off Candolim, Goa. The MZP communities were examined for the year 2013, covering different seasons and four stations (Near-shore: G3 & ...

Observational insights into chlorophyll distributions of subtropical South Indian Ocean eddies

Dufois, F.; Hardman-Mountford, N.J.; Fernandes, M.; Wojtasiewicz, B.; Shenoy, D.M.; Slawinski, D.; Gauns, M.; Greenwood, J.; Toresen, R. (Wiley-Blackwell, 2017)

The South Indian Ocean subtropical gyre has been described as a unique environment where anticyclonic ocean eddies highlight enhanced surface chlorophyll in winter. The processes responsible for this chlorophyll increase ...

Autonomous profiling float observations reveal the dynamics of deep biomass distributions in the denitrifying oxygen minimum zone of the Arabian Sea

Wojtasiewicz, B.; Trull, T.W.; Bhaskar, T.V.S.U.; Gauns, M.; Prakash, S.; Ravichandran, M.; Shenoy, D.M.; Slawinski, D.; Hardman-Mountford, N.J. (Elsevier B.V., 2020)

Data from 13 autonomous profiling BGC-Argo floats, equipped with biogeochemical and bio-optical sensors deployed between 2011 and 2016, were used to explore the potential of bio-optical methods to map deep biomass distribution ...

Ecological diversity of planktonic protists in spatial regimes of the Arabian Sea revealed through next-generation sequencing

Das, P.B.; Gauns, M.; Naqvi, S.W.A. (Elsevier, 2019)

Eukaryotic microbes inhabiting diverse ecological niches are capable of mediating biogeochemical shifts. Here, we studied the distribution patterns of protistan community in oxygen-deficient sites in the Arabian Sea and ...
