We are pleased to announce the publication of a special e-book issue, co-published by Frontiers in Marine Science and Frontiers in Microbiology.
Co-ordinated by Sophie Bonnet (M.I.O) & Cécile Guieu (L.O.V), with the support of international co-editors, this special issue brings together a series of scientific papers devoted to the impact of hydrothermal activity and undersea volcanism on ocean chemistry and plankton dynamics. It highlights the importance of interdisciplinary approaches, at the interface between oceanography, microbiology and geosciences, to improve our understanding of how the ocean system works.
This special issue is closely linked to the international project TONGA, jointly supported by the Mediterranean Institute of Oceanography (MIO) and the Villefranche Oceanography Laboratory (LOV), in the South Pacific. The project brought together researchers from twenty international institutes to study the influence of shallow submarine volcanoes on ocean biogeochemistry and the carbon cycle.
The e-book is available online, as well as all of the publications from the TONGA project.
A summary article outlining the main findings of the project is available at’following address.
Finally, a visual presentation of the expedition, co-produced by the IRD and the CNRS, is also available. available at.
Our warmest thanks go to all the authors, editors, reviewers and partners for the quality of their scientific commitment and their essential contribution to the success of this collective work.
