Ocean absolute pressure sensor network

RBRquartz³ BPR with long-term deployment rechargeable battery pack

Absolute measurements of ocean floor pressure are the only reliable means of determining if a tsunami is actually propagating offshore.

This pool comprises shallow and deep water instruments with six Enduro absolute pressure, temperature and tilt sensors. One Seabird Scientific SBE54 Tsunameter. And five RBRquartz³ BPRs (bottom pressure recorders) suitable for short and long term studies.
