透明外聚合物颗粒（TEP）是有机物（OM）通过气泡清除到海面微层（SML）并通过气泡破裂进入大气的主要传输机制。然而;关于气泡清除对 SML 中 TEP 富集的影响知之甚少。本研究考察了几种鼓泡条件和藻类种类对 SML 中 TEP 富集的影响。 SML 中的 TEP 富集通过鼓泡得到增强，鼓泡速率的影响比气泡尺寸的影响更大，并且随着时间的推移，富集度不断增加。深度剖面显示，在底层水 (ULW) 中形成的任何 TEP 聚集体都会快速（<2 分钟）传输到 SML，并且 TEP 通过鼓泡夹带在 SML 中。物种实验确定，不同浮游植物物种的存在及其随后释放的前体物质通过气泡清除进一步增强了 TEP 富集的有效性。
Transparent exopolymer particles (TEP) act as a major transport mechanism for organic matter (OM) to the sea surface microlayer (SML) via bubble scavenging, and into the atmosphere via bubble bursting. However; little is known about the effects of bubble scavenging on TEP enrichment in the SML. This study examined the effects of several bubbling conditions and algae species on the enrichment of TEP in the SML. TEP enrichment in the SML was enhanced by bubbling, with a larger impact from bubbling rate than bubble size and increasing enrichment over time. Depth profiles showed that any TEP aggregates formed in the underlying water (ULW) were rapidly (<2 min) transported to the SML, and that TEP was entrained in the SML by bubbling. Species experiments determined that the presence of different phytoplankton species and their subsequent release of precursor material further enhance the effectiveness of TEP enrichment via bubble scavenging.
