Statement on the war in Ukraine 

Without forgetting wars, tragedies and suffering in other parts of the world,
CGG wishes to express particular solidarity with Ukraine in these horrible days of war and invasion.
CGG condemns the war imposed on Ukraine by the Russian Federation,
a war that leads to terrible humanitarian crisis and bears many signs of war crimes.
We also express our appreciation of and solidarity with those scientists and
all people in Russia who spoke out and are speaking out against the war.
We understand and value that they risk persecution for their moral integrity and bravery.
We wish Ukraine an early and lasting peace, liberty, recovery and ongoing independence.

CGG is the journal of the Earth Science Institute (ESI) of the Slovak Academy of Sciences (since July 2015), formerly of the Geophysical Institute of the SAS, which merged in July 2015 with the Geological Institute of the SAS to form the ESI SAS with two divisions (geology and geophysics). CGG is a successor of the journal Contribution of the Geophysical Institute of the SAS published by the institute (once per annum, ISSN 0586-4607) since 1969 and its associated “Series of Meteorology” (once per annum, ISBN 80-224-0187-0) since 1974. Since 1998 (Vol. 28) the CGG had been published in print as 4 issues per annum. Since 2009 the 4 issues are published also electronically as Open Access fulltexts. From 2009 to 2019 CGG has been co-published by Versita, DeGruyter (successor of Versita) and recently by Sciendo (of De Gruyter). In 2014 (Vol. 44) the print production stops and CGG becomes electronic only.
