mostly rock samples, because the island was part of the volcanic arc, so lots of volcaniclastic samples (basalts, andesite, rhyolite, sideromelane) and hyaloclastites, that she can use for experiments regarding io, triton, and enceladus, which also have volcanic activity. (and one has water!) also probably a great deal of soil samples to continue testing how the different levels of elements affect the growth of plant life.

it's definitely all related to her actual work within terraforming/geology and hopefully will also benefit her future certifications lmao
