JC010: Mud volcanoes and submarine canyons


Meet...Kostas Kiriakoulakis, biogeochemist

Kostas is a Research Fellow at the University of Liverpool and he has been working in marine science since finishing his PhD. Most of his work is ultimately related to the understanding of carbon cycle, particularly in the marine/aquatic environment. The carbon cycle is a complex series of processes through which carbon is exchanged between the biosphere (organisms), geosphere (rocks), hydrosphere (water), and atmosphere (air) of the Earth.

Kostas also teaches Oceanography within the Continuing Education Department. He has been asked to review a few articles for peer-reviewed scientific journals and books and has a growing list of peer-reviewed publications as first and co-author. For a brief period (1998-1999) he worked on past climate change, he studied high resolution (decadal) climatic record of Early Holocene (10000 to 5000 years ago) from lake (Horsewater Lake Project) sediments of NW England.

Due to his high interest in advancing our knowledge about the present phenomena that occur in the ocean he intensified his research in this environment. He recognises that the ocean is a fragile ecosystem that plays an important role in controlling the climate, and that it has started to be severely affected by man, through pollution, overexploitation, habitat destruction and release of greenhouse gases.

Kostas has collaborated in several international projects dealing with marine issues. Topics that he has worked include the impact of seasonality on organic matter fluxes and composition in the open ocean (EU project: BENGAL), eco-biogeochemical investigations of cold-water coral and carbonate mound systems (EU projects: ECOMOUND, ACES, HERMES), seamounts and their effects on the marine environment (EU project: OASIS) and organic matter in submarine canyons (HERMES).

Molecular tracers (biomarkers), stable isotopes and microscopic investigations are the approaches that he has used to study the functioning of modern marine ecosystems. If you would like to get more information about Kostas, you can see his personal webpages at the Univerisity of Liverpool.
