Article Synopsis
- This study explored the collection and analysis of microplastics in the air in Auckland, New Zealand, over nine weeks, utilizing advanced microscopy and pyrolysis-gas chromatography-mass spectrometry (Pyr-GC/MS) to identify various types of airborne microplastics.
- The findings showed that smaller microplastics were found in higher numbers and emphasized the need for standardized methods when comparing microplastic research.
- The research identified eight different polymers, with polyethylene, polycarbonate, and PET being the most prevalent, and noted that wind patterns from coastal areas contributed to increased microplastic deposition on urban rooftops.
Alkenones are biomarkers produced solely by algae in the order Isochrysidales that have been used to reconstruct sea surface temperature (SST) since the 1980s. However, alkenone-based SST reconstructions in the northern high latitude oceans show significant bias towards warmer temperatures in core-tops, diverge from other SST proxies in down core records, and are often accompanied by anomalously high relative abundance of the C tetra-unsaturated methyl alkenone (%C). Elevated %C is widely interpreted as an indicator of low sea surface salinity from polar water masses, but its biological source has thus far remained elusive.

The validity of this prediction could potentially be tested through the reconstruction of the climate of the Pliocene epoch (5.33-2.
