The '''Carlsberg Ridge''' is the northern section of the [[Central Indian Ridge]], a divergent [[tectonic plate]] boundary between the [[African Plate]] and the [[Indo-Australian Plate]], traversing the western regions of the [[Indian Ocean]].<br />
<br />
The ridge of which the Carlsberg Ridge is a part extends northward from a [[Triple junction|triple point junction]] near the island of [[Rodrigues (island)|Rodrigues]] (the [[Rodrigues Triple Point]]) to a junction with the [[Owen Fracture Zone]]. The ridge started its northwards propagation in the late Maastrichtian and reached the incipient Arabian Sea in the Eocene. Then it continued to accrete basalt but did not propagate for nearly 30 Ma. Then, in the early Miocene it started to propagate westwards towards the Afar hot spot, opening the Gulf of Aden.<ref>{{Cite journal|last1=Stein|first1= C.A.|last2=Cochran|first2=J.R.|year=1985|title=The transition between the Sheba Ridge and Owen Basin: rifting of old oceanic lithosphere|journal=Geophys.

The Carlsberg Ridge is seismically active, with a major [[earthquake]] being recorded by the [[U.S. Geological Survey]] at 7.6 on the [[moment magnitude scale]] on July 15, 2003.<ref>{{cite web|title=M 7.6 - Carlsberg Ridge|url=https://earthquake.usgs.gov/earthquakes/eventpage/usp000c2ka#executive|author=USGS|publisher=[[United States Geological Survey]]}}</ref><br />

The [[submarine ridge]] was discovered by the Danish research vessel [[Dana (1921)|Dana]] during the ''[[Dana expedition|Carlsberg Foundation's Oceanographic Expedition around the world]]'' (1928–1930), better known as the ''[[Dana expedition|2nd Dana Expedition]]'', and named after the [[Carlsberg Foundation]], which funded the entire expedition and subsequent analysis and publication of results.<ref>''Earth and Space'' (The Open University, 2007), p. 222 and {{cite web|url=http://earth-info.nga.mil/gns/html/history.htm#C |title=NGA: Undersea Features History |publisher=[[National Geospatial-Intelligence Agency]] |accessdate=2013-12-01 |url-status=dead |archiveurl=https://web.archive.org/web/20130709031400/http://earth-info.nga.mil/gns/html/history.htm |archivedate=2013-07-09 }}</ref><ref>Wolff, Torben (1967).
