Fuerteventura (Canary Islands) hosts the most representative emergent Holocene marine deposits in the middle latitudes of the eastern Atlantic Ocean. The deposits consist of berms and beachrocks suggesting a cyclical cause as the orbital movement of the Earth. Radiocarbon ages place a group at around 4.2 kyr BP and another group at around 1.4 kyr BP. They have been recorded at 4 m and 3.5 m apmsl respectively. The present-day tidal amplitude is around 3 m. Assuming a similar value for the Holocene, the corresponding relative sea level rises were around 2.5 m and 2 m apmsl respectively. During these two periods, the sea surface temperatures at the southern tip of the Canary Current were colder than the present-day SST. Intercalated terrestrial deposits indicate a lowering of the sea-level at ca. 3 kyr BP.
