Microsphere abundance indicated qualitatively: — = no microspheres detected, + = <1 microsphere per field of view (FOV), ++ = 1–5 microspheres/FOV, +++ = 5–10 microspheres/FOV, ++++ = 10–100 microspheres/FOV, NA = no sample available due to damage or loss. Samples were collected by toothpick from interior and exterior of cores and stored in ~1 mL filtered 1× PBS or seawater. ID = internal identification number assigned onboard to each sample collected.
