dc.description.abstract Two Autonomous Underwater Vehicle Gliders have alternated continuous sampling of a 45-nautical mile transect line (the Newport Hydrographic Line) across the Oregon continental shelf since April, 2006. Strong currents (>25cm/s) push the gliders off their trajectories as they survey this transect line, preventing them from sampling the historically occupied stations exactly. Three methods were used to map the semi-regular glider data onto a cross-shelf line: (1) an algorithm that groups data by isobaths then block-averages the data, (2) an objective analysis that employs fixed along-isobath and cross-isobath correlation scales, and (3) a hybrid combination of the isobath-binning algorithm and objective analysis. To determine validity and accuracy, the mapping procedures are tested by comparison to moored observations at NH-10 on the Newport Line in 80m water depth while varying the spatial and temporal averaging scales. Isobath binning showed the best agreement with moored observations at the monthly timescale, while objective analysis showed the best agreement with moored observations at the weekly timescale. The hybrid method improved the agreement of the objective analysis at larger timescales. en
