Although the Indian Ocean (IO) contains a substantial fraction of these waters, abyssal pathways and upwelling in the basin remain poorly understood due to sparse observations. Here, we investigate abyssal transports using an eddy\u2010resolving regional ocean model. We find the abyssal waters flooding the IO along three distinct pathways with a net northward transport of \u223c12.5\u00a0Sv across S, consistent with observational estimates. For the first\u2010time, we identify regional hot\u2010spots of large\u2010scale abyssal upwelling that occur along ridges and continental boundaries, transferring \u223c10\u00a0Sv of abyssal waters upward, of which \u223c8\u00a0Sv returns southward as deep waters. These results provide new constraints on the structure and closure of the lower limb of the IO overturning circulation.<\/jats:p>","DOI":"10.1029\/2026gl124017","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T12:11:58Z","timestamp":1783599118000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tracing the Abyssal Water Pathways in the Indian Ocean"],"prefix":"10.1029","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3286-9432","authenticated-orcid":false,"given":"Kaushik","family":"Mishra","sequence":"first","affiliation":[{"name":"Centre for Atmospheric and Oceanic Sciences Indian Institute of Science  Bengaluru India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6543-2590","authenticated-orcid":false,"given":"Bishakhdatta","family":"Gayen","sequence":"additional","affiliation":[{"name":"Centre for Atmospheric and Oceanic Sciences Indian Institute of Science  Bengaluru India"},{"name":"Department of Mechanical Engineering The Australian Centre for Excellence in Antarctic Science University of Melbourne  Melbourne VIC Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2397-5364","authenticated-orcid":false,"given":"Kathryn L.","family":"Gunn","sequence":"additional","affiliation":[{"name":"School of Ocean and Earth Science University of Southampton  Southampton UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.
