Abstract:
|
The Ocean Bottom Seismoemter (OBS) is a key
instrument for geophysical study of sea sub-bottom layers. At
present, more relaible autonomous equipment capable of staying
underwater for long periods of time and therefore handling large
data storage are needed. This paper presents a new Ocean
Bottom Seismometer designed to be used in long period seismic
surveys. Power consumption and noise level of the acquisition
system are the key points to optimize the autonomy and the data
quality. To achieve our goals, a new low power datalogger with
high resolution and Signal–to-Noise Ratio (SNR) based on
Compactflash memory card is designed to enable continous data
acquisition. The equipment has been evaluated in the lab and is
going to be used in real environmental conditions in second
semester of 2011. |
