At the beginning of the Miocene, the northern margin of the Arabian plate, then part of the African landmass, collided with Eurasia; as a result, the [[Tethys Ocean|Tethys]] seaway continued to shrink and then disappeared as [[Africa]] collided with [[Eurasia]] in the [[Turkey|Turkish]]–[[Arabian Peninsula|Arabian]] region.{{sfn|Torsvik|Cocks|2017|p=261–264}} The first step of this closure occurred 20 Ma, reducing water mass exchange by 90%, while the second step occurred around 13.8 Ma, coincident with a major expansion of Antarctic glaciers.<ref>{{cite journal |last1=Bialik |first1=Or M. |last2=Frank |first2=Martin |last3=Betzler |first3=Christian |last4=Zammit |first4=Ray |last5=Waldmann |first5=Nicolas D. |date=20 June 2019 |title=Two-step closure of the Miocene Indian Ocean Gateway to the Mediterranean |journal=[[Scientific Reports]] |volume=9 |issue=1 |page=8842 |doi=10.1038/s41598-019-45308-7 |pmid=31222018 |pmc=6586870 |bibcode=2019NatSR...9.8842B }}</ref> This severed the connection between the Indian Ocean and the Mediterranean Sea and formed the present land connection between Afro-Arabia and Eurasia.<ref>{{Cite journal |last1=Torfstein |first1=Adi |last2=Steinberg |first2=Josh |date=14 August 2020 |title=The Oligo–Miocene closure of the Tethys Ocean and evolution of the proto-Mediterranean Sea |url=https://www.researchgate.net/publication/343661439 |journal=[[Scientific Reports]] |language=en |volume=10 |issue=1 |page=13817 |doi=10.1038/s41598-020-70652-4 |pmid=32796882 |issn=2045-2322 |pmc=7427807 |access-date=4 September 2023}}</ref> The subsequent [[Orogeny|uplift of mountains]] in the western [[Mediterranean]] region and a global fall in sea levels combined to cause a temporary drying up of the Mediterranean Sea (known as the [[Messinian salinity crisis]]) near the end of the Miocene.{{sfn|Torsvik|Cocks|2017|p=259, 267, 287}}

From 13.8 to 13.36 Ma, an evaporite period similar to the later Messinian salinity crisis in the Mediterranean ensued in the Central Paratethys, cut off from sources of freshwater input by its separation from the Eastern Paratethys. From 13.36 to 12.65 Ma, the Central Paratethys was characterised by open marine conditions, before the reopening of the Bârlad Strait resulted in a shift to brackish-marine conditions in the Central Paratethys, causing the Badenian-Sarmatian Extinction Event. As a result of the Bârlad Strait's reopening, the lake levels of the Eastern Paratethys dropped as it once again became a sea.<ref>{{cite journal |last1=Simon |first1=Dirk |last2=Palcu |first2=Dan |last3=Meijer |first3=Paul |last4=Krijgsman |first4=Wout |date=7 December 2018 |title=The sensitivity of middle Miocene paleoenvironments to changing marine gateways in Central Europe |url=https://pubs.geoscienceworld.org/gsa/geology/article/47/1/35/567589/The-sensitivity-of-middle-Miocene |journal=[[Geology (journal)|Geology]] |volume=47 |issue=1 |pages=35–38 |doi=10.1130/G45698.1 |s2cid=134633409 |access-date=7 January 2023}}</ref>

The [[Fram Strait]] opened during the Miocene and acted as the only throughflow for Atlantic Water into the Arctic Ocean until the Quaternary period. Due to regional uplift of the continental shelf, this water could not move through the Barents Seaway in the Miocene.<ref>{{Cite journal |last1=Lasabuda |first1=Amando P.
