我们提供了一种新颖的方法来计算漂流者在海洋中任意固定位置之间最有可能采取的路径。我们还提供与此路径相关的旅行时间的估计。拉格朗日路径和传播时间不仅在理解表面速度方面具有实用价值，而且在模拟浮游生物等海洋物种和塑料等漂浮碎片的运输方面也具有实用价值。特别是，估计的行程时间可用于计算估计的拉格朗日距离，在理解位置之间的连通性方面，该距离通常比欧几里得距离提供更多信息。与现有方法相比，我们的方法纯粹是数据驱动的，不需要模拟漂移轨迹。我们的方法可以在全球范围内扩展，并且可以同时处理海洋中的多个位置。此外，我们还提供与最有可能的路径和相关旅行时间相关的误差和不确定性的估计。
We provide a novel methodology for computing the most likely path taken by drifters between arbitrary fixed locations in the ocean. We also provide an estimate of the travel time associated with this path. Lagrangian pathways and travel times are of practical value not just in understanding surface velocities, but also in modelling the transport of ocean-borne species such as planktonic organisms, and oating debris such as plastics. In particular, the estimated travel time can be used to compute an estimated Lagrangian distance, which is often more informative than Euclidean distance in understanding connectivity between locations. Our methodology is purely data-driven, and requires no simulations of drifter trajectories, in contrast to existing approaches. Our method scales globally and can simultaneously handle multiple locations in the ocean. Furthermore, we provide estimates of the error and uncertainty associated with both the most likely path and the associated travel time.
