OPTIR spectra of JB_S01_B_F_1 (White Fragment) particles from marine sediment samples collected in Juara Beach, Tioman Island in August 2024 using a OPTIR Spectrometer at Krakow University, Poland

Particles from JB_S01_B_F_1 were simply placed the particles on a glass slide at once, there was no further fixation.将来自JB_S01_B_F_1的颗粒直接一次性置于载玻片（glass slide）上，未进行额外固定处理。
