SF6示踪剂释放实验(TRES)为海洋学的许多领域提供了基本见解。最近，SF6已经成为一种强大的瞬时示踪剂，产生了对大规模海洋树木的替代示踪剂的需求。由于SF5CF3的性质和行为以及注入、采样和分析技术的相似之处，SF5CF3有可能在TRES中取代SF6。在南加州海岸外的圣莫尼卡盆地，研究了SF5CF3对TRES的适宜性。2005年1月，将大约10摩尔的SF6和SF5CF3的混合物注入到800米深的等径表面上。在接下来的23个月里，两种示踪剂的浓度非常接近，表明SF5CF3是海洋中SF6的可行替代品。从实验中推断出的混合参数证实了圣莫尼卡盆地早些时候的SF6 TRE的结果。
SF6 tracer release experiments (TREs) have provided fundamental insights in many areas of Oceanography. Recently, SF6 has emerged as a powerful transient tracer, generating a need for an alternative tracer for large‐scale ocean TREs. SF5CF3 has the potential to replace SF6 in TREs, due to similarities in their properties and behavior, as well as techniques for injection, sampling, and analysis. The suitability of SF5CF3 for TREs was examined in Santa Monica Basin, off the coast of Southern California. In January 2005, a mixture of ca. 10 mol of both SF6 and SF5CF3 was injected on an isopycnal surface near 800 m depth. Over the next 23 months, concentrations of the two tracers mirrored each other very closely, indicating that SF5CF3 is a viable replacement for SF6 in ocean TREs. The mixing parameters inferred from the experiment confirmed the results from an earlier SF6 TRE in the Santa Monica Basin.
