Core sampling week, in pictures

As compared to usual, lots happened this week! Here’s a summary of what’s been happening, told in pictures.

 

Testing out our brand-new core splitter on an empty core tube.

 

My very own freshly split core!

 

The new core scanner took super-high-definition photos of my core so that changes in color and texture were easier to see.

 

Our first chance to test out the new core sampling tools we made out of sheet metal.

 

Making my way down the core! The larger sample vials will be used for lipid extractions (my main project, and what I talk about all the time), and the smaller tubes will be used to take carbon to nitrogen ratios (which can help us understand whether more terrestrial or more aquatic plants are represented).

 

This section has shells!!

 

Shell fragments held up on a spatula.

 

These samples are ready to freeze dry!
