Environmental impact of Methane seepage and sub-seabed characterization at LoVe-Node 7
This article from Muhammed Fatih Sert reports on the connectivity between cold seeps and coral reefs through the dissolved organic carbon (DOC) cycle, revealing a potential duality:– Cold seep-derived organic carbon fuels cold-water corals, acting as a carbon and energy source.– At the same time, seep-driven inorganic carbon plays a role in water column redox, […]
The 1st EMAN7 publication has been published in Journal of Geophysical Research: Oceans! In the article “Contrasting Methane Seepage Dynamics in the Hola Trough Offshore Norway: Insights From Two Different Summers”, we show that increased bottom temperature and low tide conditions boost methane activity, while strong currents and intermittent seep activity explain the thinly distributed […]
Vienna, Austria, 14–19 April 2024 Biogeochemistry of seep-impacted sediments at a cold-water coral site off the Vesterålen coast, Northern Norway Claudio Argentino1,Giuliana Panieri1,Luca Fallati2,Alessandra Savini2,Ines Barrenechea Angeles1,Abidemi Akinselure1,and Benedicte Ferré1 Methane seepage in the Hola area off the coast of Vesterålen (N. Norway) has long been known for its peculiar association with cold-water coral mounds, […]
Cádiz, Spain, 23-27 October 2023 Claudio Argentino (3rd from the right) presented data from the Hola area off the coast of Vesterålen (N. Norway) at the conference GIMS15: Gas in Marine Sediments. During the conference he described imagery, sediment and pore fluid datasets collected in 2022 that his group combined to reconstruct biogeochemical processes in the sediment and […]
The first cruise of EMAN7 occurred from June 8th to 16th 2022 onboard RV Kronprins Haakon. Using the equipment from the ship and the ROV Ægir6000, we collected visual and physical data in order to characterize the seafloor, subseafloor and the local biology as well the water column and bubbles escaping the seafloor. We also […]
