Dataset of microscopic images and infrared spectra of beach sediment samples from Juara, Salang, and Tulai in Tioman Island, Malaysia
AI summary Read the abstract
This dataset paper provides microscopic images and infrared spectra of beach sediment particles — including microplastics — collected from three beaches on Tioman Island, Malaysia. The data, covering particles in both the microplastic (<5 mm) and macroplastic (>5 mm) size ranges, is intended as a reference resource for environmental monitoring and pollution studies in marine ecosystems. Making such raw spectral and imaging data publicly available is important for building the comparative databases needed to standardize microplastic identification methods across different research groups.
This dataset presents a comprehensive collection of microscopic images, infrared (IR) spectra of particles obtained from beach sediment in Tioman Island, Malaysia. Sediment samples were collected from multiple sites across three selected beaches to identify material composition and assess the concentration of plastic particles, including both microplastics (<5 mm) and macroplastics (>5 mm), in the region. The IR spectroscopic analysis was carried out in the mid-infrared range (4000-370 cm⁻¹), enabling detailed vibrational characterization of compounds present in the samples. By integrating multiple spectroscopic techniques and vibrational calculations, this dataset provides a valuable resource for environmental monitoring, microplastic pollution studies, and material identification in marine ecosystems.
