Article 7, paragraph 1 of Legislative Decree no. 381: "The name of the Experimental Geophysical Observatory (Osservatorio geofisico sperimentale) of Trieste changes to the National Institute of Oceanography and Applied Geophysics (Istituto nazionale di oceanografia e di geofisica sperimentale) - OGS".

Prof. Iginio Marson, as Board Member, takes over the running of the Institute after the news of his proposed appointment as the President by the Ministry.

By Decree of the Presidency of the Council of Ministers, the new President of the Institute is Prof. Iginio Marson, who also retains the position of Dean of the Faculty of Engineering of the University of Trieste.

The Ministry of Education, Universities and Research (MIUR), together with the Ministry of Productive Activities (MAP), reviews the persons in charge of implementing the PNRA (National Programme for Research in Antarctica), and establishes the Consortium for the Implementation of the Programme in Antarctica, in which OGS participates. Dr. Ivo Grimaldi, Director General of OGS is a member of the Consortium's Board of Directors (Decreto Legge).

The CRS Department installs the first station for the Friuli Venezia-Giulia crustal deformation survey network, using GPS-RTK technology.

By resolution N. 4.1.3.2004, the OGS Board of Directors decides to establish the Department for the Development of Research and MArine Technologies - RIMA  - and to assign it the task, among others, of managing the research vessel "OGS-Explora".

With deliberation N.4.3.1.2005, the Board of Directors of OGS decides to extend the Institute's studies to marine biology (link to page La Biologia del Mare a Trieste) and to establish the Department of Biological Oceanography - BIO in the premises where the "Consorzio per il Laboratorio di Biologia Marina", in dissolution, in via Auguste Piccard 54, used to be.

By resolution N.3.12.4.2005, part of the staff formerly employed by the "Consorzio per il Laboratorio di Biologia Marina" is transferred to the BIO Department.

As part of a collaboration with the Instituto Antartico Argentino, a broadband seismograph is installed beyond the Antarctic Circle, at the Argentine base of San Martin. The data are available in real time on the web, via the European ORPHEUS network.

Acquisition of a new oceanographic measurement system: the glider (aliante-sottomarino), opening a new era in depth measurements. 

Renewal of the ICTP-OGS agreement for the TRIL Oceanography and Earth Sciences Scholarship Programme.

The ship "OGS-Explora", in the framework of the International Polar Year 2007-2008, leaves Kristiansund (Norway) for the only Italian polar cruise. This is the EGLACOM project (Evolution of a GLacial Arctic COntinental Margin: the Southern Svalbard ice stream-dominated sedimentary system). The project starts with funding from the Ministry of Education, Universities and Research, and also thanks to the fact that the ship was already in Norway at the end of an industrial data acquisition cruise for the Norwegian Statoil.

This was the first OGS cruise to be followed through a blog.

As part of the IPY (International Polar Year) a seismograph is installed in collaboration with the Instituto Antartico Argentino at the Argentinian station "Belgrano II" at 77°52' South. It is the second closest fixed seismograph to the pole, after the US POLA station at the South Pole. It is also connected in real time with the ORPHEUS network.

The twin-engine aircraft "Piper PA-34-200T Seneca II" is purchased for carrying out hyperspectral aerophotogrammetry.

The Board of Directors is expanded to include a further 5 ministerial appointees in order to draw up the new statutes of OGS pursuant to art. 3, paragraph 3 of the Legislative Decree 213/2009 (D.leg.vo 213/2009). 

According to press reports, it appears that the Government, in the financial manoeuvre currently under discussion, is planning to abolish the OGS as a "useless body" and subsequently merge it with the National Research Council (CNR). The OGS Presidency ascertains that the decision taken by the Ministry of Finance is also unknown to the Ministry of Research (MIUR). In the following days, the staff held a permanent assembly (assemblea permanente). The OGS receives expressions of solidarity and esteem (solidarietà e stima) from all political parties.  

In the decree-law n.78 of 31.05.2010 (decreto legge n.78 del 31.05.2010), published in the Official Gazette, Annex 2 (art. 7, paragraph 20) in the list of bodies to be suppressed, there is no OGS.

The new President of OGS is Prof. Maria Cristina Pedicchio, full professor at the University of Trieste and President of the Cluster of Biomedicine  (CBM).

According to the resolution of the Board of Directors of 21.6.2012, the Institute is divided into three "Scientific Research Sections" (Geophysics - GEO, Oceanography - OCE, Centre for Seismological Research - CRS), and one "Technological Research Section" (Research Infrastructures - IRI).

The Board of Directors decides, with regard to the name of the body, to univocally adopt the title given in Law no. 381/1999 (art. 7, c. 1), namely: " National Institute of Oceanography and Applied Geophysics - OGS".
