论文摘要
我们提供了一种新的方法，用于计算在海洋中任意固定位置之间漂流器最有可能的路径。我们还提供了与此路径相关的旅行时间的估计。拉格朗日的途径和旅行时间不仅在理解表面速度方面具有实践价值，而且还在建模海洋传播物种（例如浮游生物生物）和浮动碎屑（例如塑料）的运输方面具有实践价值。特别是，估计的旅行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时，通常比欧几里得距离更有信息。我们的方法纯粹是数据驱动的，与现有方法相比，不需要对漂流者轨迹的模拟。我们的方法在全球范围内缩放，并且可以同时处理海洋中的多个位置。此外，我们提供与最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 floating 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.
