论文摘要
与被驱动的漂流器的卫星追踪轨迹一致，但与欧拉（Eulerian）对海面高度的卫星高度测量测量的评估相矛盾，我们表明，北巴西电流环（NBCR）无能为力地绕过较小的antilles作为相干运输物质的结构。 Decacto海洋学Eulerian，基于流线的涡流检测技术无法产生正确评估的性质的性质植根于其缺乏客观性。我们通过在几乎整个范围内应用\ emph {Geodesic Eddy检测}来得出这一结论。尽管我们检测到可以将NBCR的转换为可以归类为连贯的Lagrangian涡流的NBCR，但它们通常会在到达较小的安提特斯之前经历强大的细丝和完全损失的连贯性。此外，丝状材料几乎不会渗透到加勒比海，更不用说墨西哥湾，而不是与群岛以东的环境流体混合在一起。
Consistent with satellite-tracked trajectories of drogued drifters, but at odds with Eulerian assessment of satellite-altimetry measurements of sea-surface height, we show that North Brazil Currents Rings (NBCRs) are incapable of bypassing the Lesser Antilles as structures that coherently transport material. The nature of the inability of the de-facto oceanographic Eulerian, streamline-based eddy detection technique to produce a correct assessment is rooted in its lack of objectivity. We arrive at this conclusion by applying \emph{geodesic eddy detection} on the altimetric dataset over nearly its entire extent. While we detect northwestward translating NBCRs that can be classified as coherent Lagrangian eddies, they typically experience strong filamentation and complete loss of coherence prior to reaching the Lesser Antilles. Moreover, the filamented material hardly penetrates into the Caribbean Sea, let alone the Gulf of Mexico, and not without substantively mixing with the ambient fluid east of the archipelago.
