The Ixtoc-1 oil spill (1979–80) released 475 million liters of petroleum into the Southern Gulf of Mexico (sGoM) likely causing Marine Oil Snow Sedimentation and Flocculent Accumulation (MOSSFA) to occur. A multiproxy approach including short-lived radioisotopes (²¹⁰Pb_xs), benthic foraminifera stable isotopes (δ¹³C_CaCO3), and volcanic sediment grains was used to investigate regional events (e.g. oil spills and volcanic eruptions) recorded in sedimentary records. Depleted δ¹³C_CaCO3 from 1979 to 80 outside of natural variability most likely results from petrogenic carbon deposition 100–250 km west of Ixtoc-1, possibly associated with MOSSFA. An event, characterized by increased volcanic input, depleted δ¹³C_CaCO3, and increased mass accumulation rates was consistent with the El Chichón eruption (1982) 80–100 km north of Ixtoc-1. Many factors confound the uniform distribution and preservation of these events in the sGoM. However, a multiproxy approach may aid to distinguish multiple events in the sGoM sedimentary record.

Ixtoc-1漏油事件（1979-80）向墨西哥南部海湾（sGoM）释放了​​4.75亿升石油，这很可能导致海洋油雪沉淀和絮凝剂累积（MOSSFA）的发生。一个多重代理的方式，包括短寿命放射性同位素（^210个铅_XS），底栖有孔虫稳定同位素（δ ¹³ C ^_碳酸钙），和火山沉积物颗粒被用来研究区域的事件记录在沉积岩记录（例如漏油和火山爆发）。耗尽δ ¹³ C ^_碳酸钙从1979年到80年，在自然变率以外的地区，很可能是Ixtoc-1以西100-250公里处的成因碳沉积作用的结果，可能与MOSSFA有关。的事件，其特征在于增加的火山输入，耗尽δ ¹³ Ç_碳酸钙，以及增加的质量累积速率是与ELChichón喷发（1982）Ixtoc-1的80-100公里处是一致的。许多因素混淆了sGoM中这些事件的均匀分布和保存。但是，多代理方法可能有助于区分sGoM沉积记录中的多个事件。
