1996年6月28日至7月14日，“FC 96”号考察航行由“Cornide de Saavedra”号考察船在佛兰芒角地区进行。调查包括在732米等深线内佛兰芒角进行的一系列121次随机底拖网。在每次拖网作业开始或结束时设立一个CTD站，共116个站。检测到三种不同的水团。其中两个是已知的：（a）拉布拉多海流沃茨，分布在浅滩周围;（B）中央冰帽海水，太阳能加热的拉布拉多沃茨水保留在冰帽上。这些沃茨形成了每秒4-12厘米的反气旋环流。两个水团在200米深处趋于稳定，温度约为3.5°C，盐度约为34.85 psu。第三个水团是在佛兰芒冰帽西南部200-300米处发现的斜坡水，它占据了两个独立的区域，温度高于4.5°C，盐度高于34.90 psu。这些入侵的斜坡水的佛兰芒帽似乎影响了一些鱼类的分布。特别是，它们与一些底栖物种的地理分布连续性的打破相吻合，如红鱼Marinus和S。带条肌
The research cruise "FC96" was made on the Flemish Cap area on board the RV Cornide de Saavedra from 28 June to 14 July 1996. The survey consisted of a series of 121 random bottom trawls over Flemish Cap inside the boundaries of the 732 m isobath. A CTD station was established either at the beginning or at the end of each trawl for a total of 116 stations. Three different water masses were detected. Two of them are already known: (a) Labrador Current waters, spreading around the Bank; (b) Central Cap seawater, the solar heated Labrador waters retained over the Cap. These waters made an anti-cyclonic gyre of 4–12 cm per sec. Both water masses tended to become stable at 200 m depth, with temperatures about 3.5°C and salinities about 34.85 psu. A third water mass which had not been previously described on Flemish Cap was the Slope Water, found in the southwest area of the Cap between 200–300 m, where it occupied two separate areas with temperatures higher than 4.5°C and salinities higher than 34.90 psu. These intrusions of Slope Water on the Flemish Cap seemed to affect the distribution of some fish species. In particular, they coincided with the breaking of continuity in the geographic distribution of some demersal species, like the redfish Sebastes marinus and S. fasciatus.
