Vermetids珊瑚礁在温带水域的存在，它们在地中海的扩散，以及进行14c年龄的可能性，使得Vermetids可以作为海平面变化的指标。通过同位素分析，我们提出了新的海洋气候趋势波动数据，这些数据可以解释为海表温度（SST）的变化，这些数据记录在水蛭（dendropooma peeum）礁上。同位素记录显示，在公元1600 ~ 1850年期间，δ18O相对于现今值为正值；这种偏差与被称为小冰期（LIA）的气候变冷事件有关。随后，我们可以观察到上个世纪特有的变暖趋势。这些初步结果表明，Vermetids可以被认为是地中海乃至温带地区新的海温替代资料。
The presence of Vermetid reefs in temperate waters, their diffusion in the Mediterranean Sea, and the possibility of performing14C ages allowed the use of Vermetids as an indicator of sea level changes. We present new data on sea climate trend fluctuations that could be interpreted as Sea Surface Temperature (SST) variations, recorded on Vermetid (Dendropoma petraeum) reefs, by means of isotopic analysis. The isotopic records show positive values of the δ18O relative to present-day values in the period between 1600 and 1850 AD; this deviation occurs in association with the climatic cooling event known as Little Ice Age (LIA). Subsequently, we can observe the warming trend that characterized the last century. These preliminary results indicate that Vermetids could be considered a new SST proxy-data for the Mediterranean Sea and, more generally, for temperate areas.
