Marine habitat mapping within the GR2330008 Natura site (Thalassia Periochi Kolpou Kyparissias: Akr. Katakolo - Kyparissia)

The description and mapping of marine habitat types according to Annex I of Directive 92/43/EOK (EEC, 1992) and / or the European Nature Information System (EUNIS) in 66 of approximately 300 Greek NATURA 2000 network sites, were the subject of Research Work for the Ministry of Environment Planning and Public Works of Greece. This research project, under the name "Identification and description of habitat types at sites of interest for conservation", lasted from 1999 to 2002 and was carried out by the National Centre for Marine Research (NCMR, renamed as Hellenic Centre for Marine Research - HCMR since 2003) in association with the Institute of Marine Biology of Crete (IBCM, joined to HCMR since 2003), the Aristotle University of Thessaloniki and the Fisheries Research Institute (FRI). The recognition and imprinting of marine habitat types was based on the combined use of aerial photos of scale 1:5000 acquired during the second half of 1999 for the needs of the project, data from the scientific echo sounder Sea-Bed discrimination system "RoxAnn", phytobenthos samples and in situ observations by scuba diving and underwater cameras. Regarding the sampling, hard bottom samplings were carried out using SCUBA diving. The samples were collected on hard substrates mainly in the upper infralittoral zone (30 to 50 cm below the lowest sea level). For the study of the soft bottom habitats, oceanographic cruses were carried out with the IMBC R/V “Filia”, using a Smith McIntyre sediment sampler.本数据集针对希腊约300个自然2000（NATURA 2000）保护网络站点中的66个，依据欧盟理事会92/43/EEC指令（欧洲经济共同体，1992年）附件一及/或欧洲自然信息系统（European Nature Information System, EUNIS）完成海洋生境类型的描述与制图，该工作为希腊环境规划与公共工程部的研究课题。本研究项目命名为"保护关注区域生境类型的识别与描述"，实施周期为1999年至2002年，由国家海洋研究中心（National Centre for Marine Research, NCMR，2003年起更名为希腊海洋研究中心（Hellenic Centre for Marine Research, HCMR））牵头，联合克里特海洋生物学研究所（Institute of Marine Biology of Crete, IBCM，2003年起并入HCMR）、塞萨洛尼基亚里士多德大学以及渔业研究所（Fisheries Research Institute, FRI）共同开展。海洋生境类型的识别与标注工作依托多源数据与技术手段完成：包括为满足项目需求于1999年下半年获取的比例尺1:5000的航空影像、科学回声测深仪"RoxAnn"海底识别系统采集的数据、植物底栖生物（phytobenthos）样本，以及通过水肺潜水（SCUBA diving）与水下相机开展的原位观测。关于采样工作，硬质底质采样通过水肺潜水完成，样本采集于最低海平面以下30至50厘米的上潮下带（upper infralittoral zone）硬质基质区域。针对软底质生境的研究，团队依托IMBC号"Filia"科考船开展海洋科考航次，并采用Smith McIntyre沉积物采样器完成样本采集。
