However, observations at this site may not represent the characteristics of the shelf-edge and slope current off the entire west coast of Canada. Here, we use along-track satellite altimetry data over six transects to investigate the characteristics of the surface geostrophic currents over the shelf edge and continental slope off the west coast of Canada from 1992 to 2020. It is shown that along-track satellite altimetry is well suited for monitoring longshore and climatic variations of the near-surface shelf-edge and slope currents off the west coast of Canada. It is found that the surface current over the shelf edge and slope has different features from the south to the north. While the surface current is poleward in winter and equatorward in summer off South Vancouver Island, it is poleward year-round off the rest of the west coast of Canada. The seasonal current anomalies show longshore correlation significant at the 95% confidence level, except at the North Haida Gwaii transect. The first empirical orthogonal function mode of the seasonal current anomalies is correlated with the longshore wind anomalies both off South Vancouver Island and off Oregon. However, this first mode is not correlated with either the Ni\u00f1o 3.4 index or the Pacific Decadal Oscillation index, though they often show large episodic events during strong El Ni\u00f1o and La Ni\u00f1a years. Consistent with previous findings, the present study indicates that the surface currents over the shelf edge and continental slope off the west coast of Canada are related to regional and remote longshore wind forcing.<\/jats:p>","DOI":"10.3390\/rs14061407","type":"journal-article","created":{"date-parts":[[2022,3,15]],"date-time":"2022-03-15T02:56:20Z","timestamp":1647312980000},"page":"1407","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Variability of Longshore Surface Current on the Shelf Edge and Continental Slope off the West Coast of Canada"],"prefix":"10.3390","volume":"14","author":[{"given":"Guoqi","family":"Han","sequence":"first","affiliation":[{"name":"Fisheries and Oceans Canada, Institute of Ocean Sciences, Sidney, BC V8L 4B2, Canada"}]},{"given":"Nancy","family":"Chen","sequence":"additional","affiliation":[{"name":"Fisheries and Oceans Canada, Northwest Atlantic Fisheries Centre, St. John\u2019s, NL A1C 5X1, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"151","DOI":"10.1080\/07055900.1984.9649191","article-title":"Currents along the pacific coast of Canada","volume":"22","author":"Freeland","year":"1984","journal-title":"Atmos.
