Engineers recover a Lamont ocean bottom seismometer and absolute pressure gauge package after one year on the seafloor offshore Gisborne, New Zealand.
This material relates to a paper that appeared in the May 6, 2016 issue of Science, published by AAAS. The paper, by L.M. Wallace at University of Texas Institute for Geophysics (UTIG) in Austin, Texas, and colleagues was titled, “Slow slip near the trench at the Hikurangi subduction zone, New Zealand.”

Seafloor absolute pressure gauges lashed to the deck of the R/V Roger Revelle. It is important to strap down the instruments, especially during high seas such as those sometimes found offshore Gisborne, New Zealand.

Marine technician Jay Turnbull (Scripps Institution of Oceanography) helps usher an ocean bottom seismometer onto the R/V Roger Revelle during the night after it spent a year on the seafloor offshore Gisborne, New Zealand recording ground motion.

Scientists deploy an ocean bottom seismometer and absolute pressure gauge offshore Gisborne, New Zealand from the R/V Tangaroa.

Engineers recover a Tohoku University seafloor absolute pressure gauge after one year on the seafloor offshore Gisborne, New Zealand.

Scientists and engineers aboard the R/V Roger Revelle haul a barnacle and mud encrusted absolute pressure gauge out of the ocean. The white panels help protect the instrument from trawling during its one year deployment on the seafloor.
