1986年4月，海洋号考察船参加了在北纬27-29度，西经68-71度区域进行的锋面海气相互作用实验。目的是调查一个明显的海洋锋2 -4及其对海洋和大气边界层的影响。虽然系泊设备还没有恢复，而且大部分数据分析也只是初步的，但在这里可以报告从SeaSoar 5，6（图1a）观测中得出的锋面的典型密度结构，这些观测是在收集后的几个小时内进行分析的。揭示了以前未报道的细节，包括潜没的pycnostads（弱垂直密度梯度的地区）与异常的温度/盐度签名，分裂的锋面射流和三维结构不明显的表面温度场。
In April 1986, RV Oceanus participated in the Frontal Air-Sea Interaction Experiment (FASINEX1) in the region 27-29 N, 68-71 W. The objective was to survey a pronounced oceanic front2–4 and its effect on the oceanic and atmospheric boundary layers. Although moorings have yet to be recovered, and much of the data analysis is as yet only preliminary, it is possible to report here the typical density structure of a front as derived from SeaSoar5,6 (Fig. 1a) observations, which were analysed within a few hours of collection. Previously unreported detail is revealed, including subducted pycnostads (areas of weak vertical density gradient) with anomalous temperature/salinity signature, splitting of the frontal jet and three-dimensional structure not apparent in the surface temperature field.
