Journal ArticleDOI
Methane cold seeps as biological oases in the high‐Arctic deep sea
Emmelie K. L. Åström,Michael L. Carroll,William G. Ambrose,Arunima Sen,Anna Silyakova,JoLynn Carroll +5 more
TL;DR: Faunal data, visual observations, and measurements of sediment characteristics indicate that methane is a key environmental driver of the biological system at VR and it is suggested that chemoautotrophic production enhances infaunal diversity, abundance, and biomass at the seep while MDAC create a heterogeneous deep-sea habitat leading to aggregation of heterotrophic, conventional megafauna.
Journal ArticleDOI
Geophysical and geochemical controls on the megafaunal community of a high Arctic cold seep
Arunima Sen,Emmelie K. L. Åström,Wei-Li Hong,Aleksei D Portnov,Malin Waage,Pavel Serov,Michael L. Carroll,JoLynn Carroll +7 more
TL;DR: In this article, cold-seep megafaunal communities around gas hydrate mounds (pingos) in the western Barents Sea were investigated with high-resolution, geographically referenced snapshots acquired with an ROV and a towed camera.
Journal ArticleDOI
Community succession in hydrothermal vent habitats of the Eastern Lau Spreading Center and Valu Fa Ridge, Tonga
Arunima Sen,Elizabeth L. Podowski,Erin L. Becker,Erica A. Shearer,Amy Gartman,Mustafa Yücel,Stéphane Hourdez,George W. Luther,Charles R. Fisher +8 more
TL;DR: In this article, the authors used high-resolution imagery and in situ physico-chemical data collected over 4 yr and analyzed within a Geographic Information System (GIS) to determine the formation and evolution of the Lau Basin hydrothermal vent communities.
Journal ArticleDOI

TL;DR: The presently active region of the Congo deep-sea fan (around 330 000 km2), called the terminal lobes or lobe complex, covers an area of 2500 km2 at 4700-5100 m water depth and 750-800 km offshore as mentioned in this paper.
Journal ArticleDOI
Atypical biological features of a new cold seep site on the Lofoten-Vesterålen continental margin (northern Norway).
Arunima Sen,Tobias Himmler,Wei-Li Hong,Cheshtaa Chitkara,Raymond W. Lee,Bénédicte Ferré,Aivo Lepland,Jochen Knies +7 more
TL;DR: A newly discovered cold seep from the Lofoten-Vesterålen margin (Norwegian Sea) is dominated by the chemosymbiotrophic siboglinid Oligobrachia haakonmosbiensis, but additionally displays uncharacteristic features.
