Microplastics particle morphology in a glacimarine sediment core from Disko Bay, Greenland
PANGAEA
Parga Martínez, Karla B; Andersen, Thorbjørn Joest; Posth, Nicole; da Silva, Vitor; Strand, Jakob — 2024 The dataset contains information on microplastics particle morphology from microplastic particles extracted from a sediment core from Disko Bay, Greenland. The microplastic particle morphology is based on the length to diameter ratio of the major and minor dimensions (obtained from sIMPle software and µ-FTIR data). Particles were categorized as fiber-like if the ratio was > 3 (Fiber = Y) and as fragment-like if the ratio was < 3 (Fiber = N). The dataset also includes information on polymer type, lead-210 year, sediment layer (Depth), major and minor dimensions (µm) and size class (small or large).

Microplastics accumulation in a glacimarine sediment core from Disko Bay, Greenland
PANGAEA
Parga Martínez, Karla B; Andersen, Thorbjørn Joest; Posth, Nicole; da Silva, Vitor; Strand, Jakob — 2024 The dataset provides information on microplastics particles identified in a sediment core from Disko Bay, Greenland, collected in August 2015 and dated back to 1930. This sediment core was used for the reconstruction of microplastic accumulation in the Anthropocene. The sediment layers were dated radiometically (Lead-210 and Americium-241), extracted and identified via µ-FTIR.The table contains particle count, mass, polymer type, number of particles per polymer type, sediment layer (depth), which corresponds to a specific year, and microplastics accumulation in number of particles/Kg d.w.

Limit of detection (LoD) of microplastic accumulation in a glacimarine sediment core from Disko Bay, Greenland
PANGAEA
Parga Martínez, Karla B; Andersen, Thorbjørn Joest; Posth, Nicole; da Silva, Vitor; Strand, Jakob — 2024 The dataset contains information on limit of detection of microplastic particles extracted from a sediment core from Disko Bay, Greenland. The limit of detection was calculated based on the number of particles found in the procedural blanks during sample processing and it was calculated according to (mean+3)*SD. The dataset also provides information on the number of particles found in the air blanks of the clean laboratory where the sediments samples were processed.

Microplastics size class and fractions in a glacimarine sediment core from Disko Bay, Greenland
PANGAEA
Parga Martínez, Karla B; Andersen, Thorbjørn Joest; Posth, Nicole; da Silva, Vitor; Strand, Jakob — 2024 The dataset contains information on microplastics particle size and size fractions throughout a sediment core from Disko Bay, Greenland, collected in August 2015 and dated back to 1930. Each sediment layer (depth) corresponds to a Lead-210 year categorized as Pre-plastic Boom (before 1950) and Post-Plastic Boom (after 1950). The polymer type, major and minor dimensions and the score were obtained during µ-FTIR data processing through the software sIMple. Particle size were categorized as small (20 - 100 µm) and large (>100µm) and further divided intro size fractions ((1) 20-50µm, (2) 50-100µm, (3) 100-250µm, (4) 250-500µm, (5) ≥500µm).
