The #water has been so calm at #sea for the past week in the #Tyrrhenian as #EXP402 comes to an end.

But the the #ship has more plans for it as it prepares for JR Academy, School of Rock, and #EXP403 .

One more day before we get to port in Naples. The #crew are stringing the #JoidesResolution banner along the #gangway .

Two #Chinese #scientists virtually presented to over 444,000 people in China about #EXP402 & why we are in the Tyrrhenian Sea.

They demo’d an amazing #activity that shows what happened to the #seafloor as the Tyrrhenian sea opened up 10mya.

Time to put away the pipes!

The sections of pipe are stored in the pipe racker horizontally and below the #rig floor deck. Watch as the pipe racker moves a pipe downward to the pipe rack.

The Chief Scientist, during a “sample party”, took the opportunity to make a joke towards the end of the cruise. They definitely have a sense of humor!🤣😂 #EXP402 #IODP #sample #sample party #scientist #rocks #geology #petrography #earthscience #marinescience #funny

#EXP402 isn’t done yet!

We are logging the last drill hole to measure the physical properties of the #seafloor . We can measure #electrical resistivity, density, magnetic susceptibility, and more.

#Scientificoceandrilling #offshore #ship #workneverstops #hardwork #geosciences

The SIEM Offshore #crew are made up of various #engineers , #mechanics , #sailors , and more to make sure this #ship is operated effectively.

From the #drilling shack, with its numerous gauges, the assistant driller operates the drilling pipe.

As we work through the remaining part of #EXP402 , we realize that we had our last call for core on deck and this is very likely the last time hard #rock will be cored by the #JoidesResolution .

Time to pack up! #Microbiologist , Milena, is taking home #samples of #sediment to study what kind of #microbes are present.

Some samples are pink because the #oxygen hasn't been reduced fully like it has with the #green or transparent samples.

#EXP402 #seafloor #science #ship

Section halves, both working and archive, are put away after they have been processed for #ship board #analysis .

Every few days they are packed up and taken down to a giant refrigerator to hold them until we get back to #port .

#EXP402 #sientificoceandrilling #ship #research

Not quite #rock but not quite #sediment .

These cores are compacted #layers of #salt that was left behind when the #Mediterranean suffered an extremely dry period. The left side is red because iron oxides are present.

#EXP402 #scientificoceandrilling #minerals #geosciences

Some #microfossils are so unique to certain #sedimentary layers that they are are used as age estimates. If found in high abundance S. seminulina is about 5.33 million years old, & G. excelsa is a little less than 1 million years old

#EXP402 #scientificoceandrilling #SEMimages

The marine #crew with SIEM Offshore are in charge of #sailing the #ship , keeping it on course, and more. In 60 seconds meet our 2nd mate and what #responsibilities he has while on #shift !

#EXP402 #scienceatsea #offshorejobs #team #ship life #skills #careers

The left core has more organic rich matter, referred to as Sapropel, which is known for its darker #color .

The right core encountered a mass transport event, where the #sediment layers were churned up, possibly due to an #underwater landslide.

#EXP402 #geosciences #science

Instead of #traveling with gallons of freshwater, we can make it on board!

Our #desalinator sits at the back of the ship & is maintained by our #engineering #crew . It is able to supply the #ship with all its #freshwater needs.

#EXP402 #drinkingwater #selfsufficient #offshore

Scientists on #EXP402 shared why they thought IODP is important to them & the #public .

It is an impressive #program to reflect on as the International Ocean Discovery Program (IODP) phase comes to an end.

#scientificoceandrilling #sciencecommunication #collaboration

Preparing for a 2 month expedition takes a lot of anticipating needs. Meet our materials coordinator, John, who ensures that our #inventory is up to date and available for the current and upcoming #expedition crews.

During the 2nd Science & Art broadcast Eirini and Tessa guided drawers through the colors and shapes of a serpentine matrix moving through the multicolored #crystals of #olivine .

Thank you Lee Stelea ⭐️ for joining!

#EXP402 #ocean drilling collected 113.89 meters of hard #rock across 4 locations, meaning we drilled the length of 2.5 Derricks into the #seafloor .

Thank you to the SIEM crew who manage the drilling #operations expertly to ensure we get one core every few hours!
