說明
The dataset describes the megabenthic biodiversity that has been recorded in five locations at the upper mesophotic zone of the National Marine Park of Alonissos Northern Sporades. The expedition ran in the summer of 2021 with a focus on the study of the structure of the octocoral habitats with emphasis on the forests of Eunicella cavolini and Paramuricea clavata. Non-invasive methods have been applied to collect the relevant information. This includes 4K GoPro cameras with lights and scaled laser beams along with an underwater camera system with strobes. The provided dataset is preliminary and far from being considered complete; however, it sets the foundation for new information to be added in future expeditions.

取樣方法
Equipment used are GoPro cameras, Canon Cameras, Visual Census. During June 2021, technical scuba diving operations were carried out at every site to verify the occurrence of coral forests and perform noninvasive monitoring from 30 to 45 m depth, with qualitative explorations up to 60 m depth. Underwater videos were carried out using 4K cameras equipped with two video lights of 12,000 lm each and two parallel laser beams for scaling. Image analysis and processing for the coral forests were performed using ImageJ/Fiji software, and sampling units of 2.5 ± 0.2 m2 were defined along each transect, according to the minimal area used for the quantification of Mediterranean octocoral habitats.
| 研究範圍 | Octocoral forests created by the yellow sea fan Eunicella cavolini and the red sea fan Paramuricea clavata were studied at the National Marine Park of Alonissos Northern Sporades (Aegean Sea, Greece), between 30 and 45 m depth, in order to assess their conservation status and the occurrence of both natural and anthropogenic stressors. |

方法步驟描述:
- Based on local knowledge and interviews with diving centers, five sites have been selected for the assessment of upper mesophotic coral forests. Three of them are located in the straits of Skopelos–Alonnisos, at Agios Georgios islet and Mikro islet, and at the tip of Fanari in Alonnisos. Two more sites are located 1.5 nautical miles northeast of Dyo Adelfia islet, at the so-called Barketa reef, and off the twin islets Moro and Moules.
