Harmful Algal Event Database (HAEDAT)

The Harmful Algal Event Database (HAEDAT) is a component of the Harmful Algal Information system (HAIS) within the International Oceanographic Data and Information Exchange (IODE) of the Intergovernmental Oceanographic Commission (IOC) of UNESCO, and in cooperation with ICES, and PICES. The HAEDAT is a meta database containing records of harmful algal events. HAEDAT contains records from the ICES area (North Atlantic) since 1985, and from the PICES area (North Pacific) since 2000. IOC Regional networks in South America, South Pacific and Asia, and North Africa have recently started contributing. This instantiation of the HAEDAT database contains all species occurrences associated with harmful algal events, including abundance and toxicity ranges.有害藻华事件数据库（Harmful Algal Event Database, HAEDAT）是联合国教科文组织（UNESCO）政府间海洋学委员会（Intergovernmental Oceanographic Commission, IOC）下属国际海洋数据与信息交换系统（International Oceanographic Data and Information Exchange, IODE）内的有害藻华信息系统（Harmful Algal Information System, HAIS）的组成部分，并与国际海洋考察理事会（ICES）、北太平洋海洋科学组织（PICES）开展合作。该库为元数据库，收录各类有害藻华事件的相关记录。自1985年起，HAEDAT收录北大西洋ICES海域的相关记录；自2000年起，收录北太平洋PICES海域的相关记录。南美洲、南太平洋、亚洲及北非的IOC区域网络近期已启动数据贡献工作。 本次发布的HAEDAT数据库实例收录了与有害藻华事件相关的全部物种出现记录，涵盖物种丰度与毒性范围数据。
