Research Project
The long-term development of cold-water corals and coral mounds controlled by changing environmental conditions, West Melilla Coral Province, Alboran Sea, west Mediterranean Sea
Scleractinian cold-water corals (CWCs) have a world-wide distribution and termed as ‘hotspots of biodiversity’ due to their roles in providing habitats for species rich ecosystems in bathy zones as they can form large sea-bed structures. Lophelia pertusa and Madrepora oculata are the most prominent, and the only species that can form coral mounds, which consist of coral fragments, coral associated fauna fragments and hemipelagic or pelagic sediments, and provide the perfect materials for paleoceanography scientific research.
Two different CWCs mound provinces were found in the eastern Alboran Sea (west Mediterranean Sea), with patches of living CWCs found in the Eastern Melilla Cold-water Coral Province (EMCP) and no living CWCs were observed in the Western Melilla Cold-water Coral Province (WMCP). In geological time scales, coral growth in the EMCP was related the enhanced productivity during B/A interstadial and the Early Holocene, with high coral mound aggradation rates up to 419 cm ka-1, while little is known about the development of CWC in the WMCP due to lack of sediment core materials. Besides, the development of CWCs in Alboran Sea is different from other areas in Mediterranean Sea since Holocene. Thus my study will address the long-term development of CWCs in the WMCP, also to get a closer grip on the main forcing factors controlling CWC development in the EMCP and WMCP.
In order to unravel the development of CWC mounds in WMCP, on-mound and off-mound sediment cores were collected during R/V Maria S. Merian cruise MSM 36 cruise. Paleoceanography records from the off-mound core and records of CWCs development from on-mound cores will be reconstructed to provide us detailed information of development of CWCs in this region.
