1. RAW

Données brutes Manta (format propriétaire)

Format Propriétaire

Source: Hydrophones + Géophones Manta

Résolution ADC: 24-bit, ±2.5V

2. SEGY

Conversion intermédiaire via mantasegy (Box64/ARM)

mantasegy (Box64/ARM)

Format: SEG-Y Rev.1

Conversion: Binaire Manta → SEG-Y

3. Normalisation

Conversion ADC → valeurs physiques calibrées

Python + Calibration

Géophones (SM-24):

v(m/s) = (ADC / gain) × 28.8 V/(m/s)

Hydrophones:

P(µPa) = (ADC / gain) × sens(µPa/V)

ADC → Voltage:

V = ADC × (5.0 / 2²⁴)

Normalisation trace:

(trace - mean) / std
