It was published in the Official Gazette (DOU) of Brazil, Section 3,
pp. 25-37, of 4 of June 2012 the call for several permanent positions
at the Observatorio Nacional / MCTI in Rio de Janeiro, Brazil.****
Observatorio Nacional -MCTI is a 185 years old premier research institute
in Brazil developing both research and teaching at graduate levels in many
areas of geophysics. It houses a newly established National Equipment Pool
whose vast instrument collection includes 60 broadband seismometers, 340
high-frequency single-component seismometers, 12 broadband magnetotelluric
systems, 40 long period magnetotelluric systems, 3 absolute gravity
stations, 12 differential GPS systems, 6 Scintrex CG5 gravity systems, and
6 Overhauser magnetometers. The Pool is supported by a well-equipped
workshop and advanced parallel computing facilities.****
