Revelle Blog #6 Seafloor sampling

10 months ago by Sarah Seabrook and Dr. Claire McKinley

A critical mission for this research project, is to get samples of sediment deep beneath the seafloor to track deep fluid flow through the Hikurangi subduction zone. Fluid conditions affect the likelihood and type of earthquakes that occur at faults.

Revelle Blog #5 How do we get pore water?

10 months ago by Dr. Claire McKinley

We collect samples of sediment called cores from the seafloor using a giant straw shaped cookie cutter or by taking small 'hand held' cores using Jason, a high tech robotic submarine.

Revelle Blog #4 Mapping the ocean

10 months ago by Dr. Claire McKinley

Mapping is the first thing we do at every location. We are mapping the ocean to locate bubbles, because bubbles will lead us to sites on the seafloor that have fluid flow, or seeps. We do this so when we take cores, measure heat flow and deploy instruments we know...

Revelle Blog #3 What is pore water?

10 months ago by Dr. Claire McKinley

One of the main goals of this voyage is to measure and study pore water to figure out trapped water’s role in allowing slow slip earthquakes to occur. Slow slip earthquakes is when movement between the tectonic plates occurs slowly across the subduction zone, over a period of weeks to...

Revelle Blog #2 Why come all this way?

11 months ago by Dr. Claire McKinley

We are on the New Zealand subduction zone to study the causes of earthquakes in the region. A subduction zone is where one tectonic plate subducts, or is forced below, another. They are also where the biggest earthquakes and tsunamis occur.

Revelle Blog #1 To sea we go

11 months ago by Dr. Claire McKinley

We have finally departed Wellington aboard the US research vessel Revelle, on its second of three voyages studying the Hikurangi subduction zone. A subduction zone occurs where one plate dives under, or subducts below, another plate.

Preparing for the big one on the Hikurangi Subduction Zone

11 months ago by East Coast LAB (Life at the Boundary)

Planning for a rupture of New Zealand’s largest fault - the Hikurangi subduction zone - has kicked into motion, with scientists certain it’s a case of when, not if.
