(from Geoviten-ekstern 18.12.2009) Our planet is a work of life. Biological and geological processes have been inextricably linked since life first emerged on Earth. Learning more about when and where life first evolved is central to understanding how geobiological systems have shaped our planet. The answers to these questions are preserved in sparse and fragmentary early Archean rocks that... Read more
Det norske forskningsskuta "G.O. Sars" havner i klasse med verdens største containerskip og bilfrakteverktøy i dokumentaren "Mighty Ships".
DNA-sequencing gives us the possibility to study the genetic code of all living organisms. Many researchers today take advantage of developments in molecular biology technology that have led to the development of massive parallel pyrosequencing.
CGB researchers re-visited Loki's Castle, the world's northernmost identified Black Smoker, and Håkon Mosby Mud Volcano. This year Discovery channel was also onboard.
CGB will be taking an active role in an Astrobiology summer school addressing these issues 29 June-13 July 2009. Professor Nils-Kåre Birkeland will be one of the lecturers, lecturing on the "Genetics of thermophiles" and the "Molecular basis of the stability of biomoleculees in hot environments". Researcher Ida Helene Steen and research assistant Solveig Hoem are leading some... Read more
Guest researcher and mineralogist Beata Smieja-Król says that peatland is only interesting when it is polluted!
Professor Lise Øvreås is participating in a research cruise in the Lau basin, east of Fiji, where scientists are investigating extreme organisms living around the hydrothermal vents found there.
Written by Friederike Hoffman, Sars Centre. Sponges are major constitutes of coral reef and deep sea communities. They excrete high amounts of ammonium and, due to the activity of associated microorganisms, nitrite and nitrate; these are essential nutrients, and sponges are thus considered as important nutrient sources in the marine ecosystem.
In 2000 during an oceanographic cruise a group of researchers stumbled upon a unique discovery – a completely new kind of hydrothermal vent field.
Preliminary analysis of 3650m of pristine rock core is revealing some unexpected data that may provide insights into perhaps the earliest perturbations of the global carbon cycle.
A book chapter by Vigdis Torsvik and Lise Øvreås... The book is entitled: Microbial diversity, life strategies, and adaptation to life in extreme soils. I: Microbiology of Extreme Soils. Springer 2008 ISBN 978-3-540-74230-2. s. 15-43.
They are studying the microorganisms found around the hostile environments found in the deep sea and at hydrothermal vents to learn more about how they collaborate to build up chemosynthetic ecosystems that support unique communities of larger organisms.
