Dr. Evan J. GowanFatourou et al use biological proxies to investigate the connection of the Gulf of Corinth in Greece with the Mediterranean Sea during the Middle and Late Pleistocene. The connection for the past 400,000 years has been through the western Rion Sill, which is currently at 60 m depth. During glacial periods, sea level fell sufficiently to isolate the Gulf of Corinth from the Mediterranean Sea. Therefore, this record can be used as a way to estimate global ice volume. The major glacial periods of MIS 18, 14, 8, 6, 4 and 2 show a complete isolation of the Gulf.The major interglacials of MIS 17, 13, 11 and 9 indicate fully connected conditions. MIS 7 shows fluctuations, indicating that ice volume varied. This is perhaps not surprising, since there is a large interruption in MIS 7 with a sharp rise in δ¹⁸O in the marine records, likely a brief glaciation.During MIS 5, there is also fluctuations, with evidence of isolation during the MIS 5b stadial. During MIS 3, there is evidence that sea level must have risen enough that there was periodically a connection with the Mediterranean Sea (i.e. sea level > -60 m).Obviously, pin-pointing a specific sea level from these data is difficult, since the height of the sill likely varied due to tectonics, and the "connection" based on these proxies probably does not depend precisely on sea level being above or below -60 m.<a href="https://fediscience.org/tags/Paleoclimate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Paleoclimate</a> <a href="https://fediscience.org/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://fediscience.org/tags/Greece" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Greece</a> <a href="https://fediscience.org/tags/Mediterranean" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mediterranean</a> <a href="https://fediscience.org/tags/IceSheets" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IceSheets</a><a href="https://doi.org/10.1016/j.quascirev.2025.109393" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://doi.org/10.1016/j.quascirev.2025.109393</a>

Dr. Evan J. GowanIn episode 5 of the Raised Beaches Podcast, I highlighted five papers. These cover the subjects of determining past sea level position from beach ridges, Holocene sea level, an orbital theory of interglacials, and two paleo sea level compilations.

Bob LeFridge :tinoflag:I live on a beach and this is quite big.Minimum floor levels are being raised in low-lying coastal parts of Dunedin, effective today.When my neighbour built about ten years ago, the minimum was 0.5m. The new minimum floor level is 3.05m - 3.17m above sea level "in certain areas".Three metres! While I approve the forward thinking, we'll have a lot of houses on poles.

Dr. Evan J. GowanI have released episode 5 of the Raised Beaches Podcast, a podcast about paleoclimate, Earth science and global change! This episode's deep dive is on the greenhouse effect. Get it in the following link or wherever you get your podcasts. In the intro, I talk about going to watch Sakurajima Volcano erupt, an earthquake I felt in January, my efforts to download data from NOAA and how US government agencies are being shut down, and a commentary on DEI.I discuss in the deep dive how the greenhouse effect works, and why greenhouse gases are needed to keep the planet inhabitable. In the second part I discuss the history of the discovery of the greenhouse effect and how it got its name, and the greenhouse effect on Venus and Mars.Finally, I discuss in the papers section a recent paper I am coauthor on, led by Alessio Rovere, about determining past sea level position from a beach ridge in Argentina. I discuss 4 other papers. <a href="https://fediscience.org/tags/Paleoclimate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Paleoclimate</a> <a href="https://fediscience.org/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateChange</a> <a href="https://fediscience.org/tags/Podcast" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Podcast</a> <a href="https://fediscience.org/tags/SeaLevel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SeaLevel</a> <a href="https://fediscience.org/tags/NOAA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NOAA</a> <a href="https://fediscience.org/tags/Volcano" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Volcano</a><a href="https://raisedbeaches.buzzsprout.com/2401751/episodes/16758479-episode-5-the-greenhouse-effect" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://raisedbeaches.buzzsprout.com/2401751/episodes/16758479-episode-5-the-greenhouse-effect</a>
