| Definition | A broadband ocean bottom seismometer system designed for seafloor deployment for long-term tsunami and earthquake research. It features a Guralp CMG-40 T broadband seismometer encased in a titanium pressure tube, mounted to a titanium frame featuring yellow syntactic foam flotation units, titanium pressure tubes containing batteries and a GEOLON-MCS data recorder, plus a flasher, radio beacon, signal flag, anchor and acoustic release. The flotation units of the LOBSTER-7300 are made of denser syntactic foam than the LOBSTER-6000. The titanium pressure tubes of the LOBSTER-7300 are also thicker than the LOBSTER-6000. The OBS system can be deployed for up to 1 year. The LOBSTER-7300 K/MT 517 is depth-rated to 7300 m. The Guralp CMG-40 T seismometer has a tilt range of +/- 2.5 degrees, and a dynamic range of 148 dB at 1 Hz and 151 dB at 5 Hz. The seismometer also has an operating temperature from -20 to +75 degC, and an output sensitivity of 2000 V/m/s (2 �� 1000 V/m/s) differential standard output (full-scale clip level of 8.8 mm/s). | |
