文摘
- •
Flow processes at the sediment–water interface are similar in streams and the ocean.
- •
The MATTSI computer program detects porewater exchange using heat as a tracer.
- •
Flushing is approximated in a 1-D framework using an effective thermal dispersivity.
- •
The model detected episodic sub-seafloor flushing at a continental shelf site.
- •
Flushing occurred during periods with high current velocity and thermal instability.
