Surface Geostrophic Currents in the Gulf of Mexico
Go To Frame =
Surface geostrophic currents are derived from the near real-time satellite altimetry product produced by AVISO (www.aviso.altimetry.fr) and served via the E.U. Copernicus Marine Environment Monitoring Service (CMEMS)
(marine.copernicus.eu/). A mean dynamic height of mdt_cnes_cls2013 is added to the sea level anomaly
data to get sea surface height (SSH). Geostrophic currents are computed from the gradient of the SSH, which approximates the actual surface currents. A quantitative assesment of the altimetry product using the drifter data
observations in the estern Gulf of Mexico can be seen in Liu et
al. . This product is further used in the analysis of the Gulf of Mexico Loop Current patterns [Liu et al., 2016a; Weisberg and Liu,
2017] and the West Florida Shelf offshore forcing index [Liu et al., 2016b].
