N2 - Microplastics are both pervasive in the marine environment and highly detrimental to it. In this study, we investigate the abundance, distribution, and characteristics of microplastics in surface waters on a transect spanning 6 major ocean current regions in the Atlantic Ocean from Scheveningen (the Netherlands) to Montevideo (Uruguay). 50 surface trawls were completed with a manta net (mesh 500 µm, cod 333 µm) and particles were analyzed in the laboratory including polymer type identification with ATR-FTIR spectroscopy. An overall abundance of 0.011 items/m³ was found with no significant difference between microplastic abundance and distance to coast. The dominant polymer types were HD-PE (63.5 %) and PP (28.3 %), shape was fragments (88.6 %), and color was white (59.1 %). We conclude that this study's findings reaffirm the widespread presence of microplastic pollution in the Atlantic Ocean, contributing data from consistently under-sampled regions such as the South Atlantic.
