Mud, Mud, Glorious Mud

By Mikala Maher, University of Canberra

After what seemed liked forever, and exceeded excitement on Christmas morning, we finally had sediments to explore. Over the last two days we have deployed a total of four Kasten Corers and two sediment grabs from the shallow shelf to the deep marine environment within a Submarine canyon environment.

A view of the sediment grab sampler being deployed off the starboard winch from a few levels above.  The upper deck is a safe spot for CAPSTAN students to stand without being in the way when they want to see the deployment.
The Smith Mac sediment grab sampler is deployed over the side of RV Investigator to collect surface sediments from 500 m below the ocean surface.

With adrenaline kicking in, samples were prepared and while desperately waiting for samples to dry discussions where held proposing suggestive theories as to what secrets the mud will contain, consulting with the new bathymetry and causing a rave in the observations room.  

Emotions were high with the excitement ongoing deployments and exploring the prepared samples and boy do we have some spectacular organisms and some outstanding structures.

Tag lines are put on the kasten core to assist in recovery from the A-frame on the back deck of RV Investigator during the 2019 CAPSTAN marine science training voyage.

My research will be looking at exploring a link to Last Glacial Maximum with shelf sediments. Without further ado, and with credit to the Ice Age, I present to you the sedimentology Mud song.

Mud, glorious mud…we’re anxious to dry it

Two cores a day, our favorite deployment!

Just picture a Turbidite, matching the Bouma sequence

Oh, mud, wonderful mud, marvelous mud, glorious mud.

Mud, glorious mud,

Slide smears and wet sieves

Mud made from plankton

Or hemipelagic rain.

Do nothing but sample,

On mud, magical mud, wonderful mud, marvelous,

MMUUDD

Mud, glorious mud

Freshly plucked from the sea floor

A little smelly but filled with beauties

Soon, we’ll hit the jackpot

Just thinking of gravity cores

Puts us in a mood for

Mud, glorious mud, marvelous mud, fabulous mud,

Beautiful mud,

Magical mud,

GLORIOUS MUD.

Once secured to saw horses in the wet-dirty lab, one side of the kasten core is removed to reveal the glorious mud inside.  Once open, scientists 'clean' the core and then describe it before proceeding to take discrete samples.
Beautiful mud, Magical mud, Glorious mud!
