OCE 96-34495 O'Donnell The project will apply a generalized inverse method to the problem of estimating tides and residual currents in under-sampled fields such as those generated by Acoustic Doppler Current Profilers (ADCPs) operated from moving ships. Shipboard ADCP sampling suffers from inherent limitations which necessitate separation of tides and low- frequency flows during post-processing. The generalized inverse method will improve on existing least-squares fitting techniques by explicitly including dynamical constraints. In addition to development and assessment of the generalized inverse method, emphasis will be placed on evaluating and designing optimal sampling strategies for use in field studies.

OCE 96-34495 O‘Donnell该项目将应用一种广义逆方法来估计欠采样区域中的潮汐和残流，例如从移动中的船舶上操作的声学多普勒海流剖面仪(ADCP)所产生的潮汐和残流。舰载ADCP采样存在固有的局限性，需要在后处理过程中将潮汐和低频水流分开。广义逆方法将通过显式地包含动力学约束来改进现有的最小二乘拟合技术。除了开发和评估广义逆方法外，还将重点评估和设计用于实地研究的最佳抽样策略。
