We introduce a database of hydrothermal vent fluid compositions extracted from peer‐reviewed publications. The database includes general fluid parameters (e.g., temperature, salinity, and pH) as well as major‐, minor‐, and trace‐element concentrations (including rare earth elements) of dissolved cations, anions, reduced carbon compounds, and gases. In addition, isotopic compositions of elements and molecules are included. Each parameter in the database is given in a uniform unit and enables direct intercomparison of data from the incorporated sources. The database provides detailed information about geographic location, the date of sampling, and a broad set of supplementary information that enables clear identification of each individual sample and the original data source. This type of metadata was used to merge compositional data for discrete vent fluid samples that originate from different publications. Hence, the database provides a more complete set of compositional parameters than the original sources do. To facilitate operability, the database is provided as ®Excel sheet, which enables users to visualize, sort, filter, and evaluate the database in a straightforward way. The sample information metadata enables extraction of available vent fluid data for specific regions, tectonic settings, host rock types, etc. The database will be a useful tool in determining (1) mechanisms that set fluid chemistry, as well as (2) regional and global geochemical fluxes across the seabed. To demonstrate the extent of the database, we examine the global distribution of magnesium, chloride, and sodium concentrations in vent fluid samples that are incorporated in MARHYS Database.

MARHYS（海洋水热解决方案）数据库：船用热液排放流体，终端构件和海水成分的全球汇编

我们引入了一个从同行评审出版物中提取的热液排放流体成分的数据库。该数据库包括常规流体参数（例如温度，盐度和pH），以及溶解的阳离子，阴离子，还原的碳化合物和气体的主要，次要和痕量元素浓度（包括稀土元素）。另外，包括元素和分子的同位素组成。数据库中的每个参数均以统一单位给出，并且可以直接比较来自合并来源的数据。该数据库提供有关地理位置，采样日期以及广泛的补充信息的详细信息，这些信息可以清楚地标识每个单独的样本和原始数据源。这种类型的元数据用于合并来自不同出版物的离散排气流体样品的成分数据。因此，该数据库提供了比原始来源更完整的组成参数集。为了促进可操作性，该数据库以®Excel表格的形式提供，使用户能够以直观的方式可视化，排序，过滤和评估数据库。样本信息元数据可以提取特定区域，构造背景，基质岩石类型等可用的排空流体数据。该数据库将是确定（1）设置流体化学机制的有效工具，以及（2）区域和构造的有用工具。整个海床的全球地球化学通量。为了说明数据库的范围，我们检查了镁，氯化物，
