Marine habitat mapping within the GR2330007 Natura site (Paraktia Thalassia Zoni apo Akr. Kyllini eos Toumpi - Kalogria)

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.本研究针对希腊约300个NATURA 2000网络保护地中的66个，依据《92/43/EEC指令》（欧洲经济共同体，1992）附录一及/或欧洲自然信息系统（European Nature Information System）开展海洋生境类型的描述与制图，该工作由希腊环境规划与公共工程部委托开展。该项目命名为"保护关注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年更名为希腊国家海洋研究中心——HCMR）牵头，联合克里特岛海洋生物学研究所（Institute of Marine Biology of Crete, IBCM，2003年并入HCMR）、塞萨洛尼基亚里士多德大学以及渔业研究所（Fisheries Research Institute, FRI）共同完成。海洋生境类型的识别与建档标注，整合使用了以下多源数据：为该项目需求于1999年下半年采集的1:5000比例尺航空影像、基于科学回声测深仪海底识别系统"RoxAnn"获取的探测数据、底栖植物样本，以及通过水肺潜水与水下摄像开展的原位观测。关于采样工作：硬质底质采样采用水肺潜水完成，样本主要采集于潮下带上带（最低海平面下30至50厘米处）的硬质底质区域。针对软底质生境的研究，依托IMBC"菲莉亚"号科考船开展海洋考察航次，采用史密斯-麦金泰尔采泥器完成沉积物采样。
