We introduce a new method to correct the glider\u2019s along-track coordinate, which is, in general, biased by the unsteady relative movements of the glider and the eddy, yielding large errors on horizontal derivatives. Here, we take advantage of the synopticity of satellite along-track altimetry to apply corrections on the glider\u2019s position by matching in situ steric height with satellite-measured sea surface height. This relocation method allows recovering the eddy\u2019s azimuthal symmetry, precisely estimating the rotation axis position, and computing reliable horizontal derivatives. It is shown to be particularly appropriate to compute the eddy\u2019s cyclo-geostrophic velocity, relative vorticity, and shear strain, which are otherwise out of reach when using the glider\u2019s raw traveled distance as a horizontal coordinate. The Ertel potential vorticity (PV) structure of the warm core ring is studied in details, and we show that the PV anomaly is entirely controlled by vortex stretching. Sign reversal of the PV gradient across the water column suggests that the ring might be baroclinically unstable. The PV gradient is also largely controlled by gradients of the vortex stretching term. We also show that the ring\u2019s total energy partition is strongly skewed, with available potential energy being 3 times larger than kinetic energy. The possible impact of this energy partition on the Loop Current rings longevity is also discussed.<\/jats:p>","DOI":"10.3390\/rs13132456","type":"journal-article","created":{"date-parts":[[2021,6,23]],"date-time":"2021-06-23T11:28:41Z","timestamp":1624447721000},"page":"2456","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Dynamical Structure of a Warm Core Ring as Inferred from Glider Observations and Along-Track Altimetry"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9465-0113","authenticated-orcid":false,"given":"Thomas","family":"Meunier","sequence":"first","affiliation":[{"name":"Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2988-0307","authenticated-orcid":false,"given":"Enric","family":"Pall\u00e1s Sanz","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Ensenada 22860, Mexico"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1712-729X","authenticated-orcid":false,"given":"Charly","family":"de Marez","sequence":"additional","affiliation":[{"name":"Laboratoire d\u2019Oc\u00e9anographie Physique et Spatiale, 29280 Plouzan\u00e9, Brittany, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7449-6614","authenticated-orcid":false,"given":"Juan","family":"P\u00e9rez","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Ensenada 22860, Mexico"}]},{"given":"Miguel","family":"Tenreiro","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Cient\u00edfica y de Educaci\u00f3n Superior de Ensenada, Ensenada 22860, Mexico"}]},{"given":"Angel","family":"Ruiz Angulo","sequence":"additional","affiliation":[{"name":"Institute of Earth Sciences, University of Iceland, 102 Reykjavik, Iceland"}]},{"given":"Amy","family":"Bower","sequence":"additional","affiliation":[{"name":"Woods Hole Oceanographic Institution, Woods Hole, MA 02543, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"422","DOI":"10.3389\/fmars.2019.00422","article-title":"OceanGliders: A component of the integrated GOOS","volume":"6","author":"Testor","year":"2019","journal-title":"Front.
