Abstract

Abstract

En 中文
• A compact speaker-type seismic source enables low-impact offshore CO₂ storage monitoring. • Source miniaturization (∼50 kg) allows deployment from small vessels and autonomous platforms. • Highly repeatable signals achieve airgun-equivalent amplitudes through stacking. • Deep (>2 km) subsurface reflections are imaged at nearshore potential CCS sites. • Compatibility with DAS enables scalable, quasi-real-time, continuous offshore monitoring.
