"It is just shallow water geophysics for the team of Instituto de Pesquisas de Tecnologicas and Dr Luis Antonia Pereira de Sousa.

Taiaçupeba Lake - Suzano, Sao Paulo with 2 to 7 m depth only.

Meridata Dual chirp 2-8 kHz abd 10-20 kHz + SIG boomer (500-2000 Hz)."

Seismic survey in Viana do Castello, Portugal

Geosub  Prospecção Geomática e Ambiente, Lda has been awarded an study in the Port of Viana do Castello including a geophysical survey. Geosub has rented the SIG boomer system, from our rental pool. The quality of the data was important. On a small boat, a pole can serve as an outrigger to keep the streamer from the turbulence of the propeller's wash.

Geophysical campaign in the Ionian sea

SIG sparker and multi-channel acquisition has been used during the geophysical campaign CRACK onboard the R/V "Le Téthys II", with international teams of institutes and universities (IUEM/UBO Brest, Ifremer Brest, Univ. of Montpelliers, GEOMAR Kiel, and Univ. Kiel, Univ. Catania, Italia, and Univ. of Malta). The objective of this survey was to identify and quantify the submarine deformation alond the East coast of Sicily, in the coastal region of Etna-Catalane. 600 km of sparker profiles, in water depths of less than 150 m, have led to images of sediments over 100-200 m.
