Geochemistry of hydrothermal fluids at the Lucky Strike Hydrothermal Field data from the EMSO-Azores observatory, 2010

High temperature hydrothermal fluids are collected during the MOMARSAT 2010 cruise by gas-tight fluid sampler manipulated and triggered by the hydraulic arm of the submarine vehicle (ROV Victor6000). Several hydrothermal vents are sampled, namely : Aisics, Tour Eiffel, Cypress, Crystal.

Several chemical analyses are performed aboard the research vessel: such as salinity and d20/20 by refractometer, pH by electrode (pH standard 4.01 and 7), Conductivity, salinity and total dissolved solid (TDS) by electrode (standard solution at 1413 µS/cm).

本数据集的高温热液流体采集自MOMARSAT 2010航次，由无人遥控潜水器（ROV Victor6000）的机械臂操控并触发的气密流体采样器完成采集。本次航次共对多处热液喷口进行采样，分别为：Aisics、Tour Eiffel、Cypress、Crystal。

本次采样配套在调查船上开展了多项化学分析项目：包括通过折射仪测定的盐度与d20/20值、采用电极法（以pH标准液4.01和7校准）测定的pH值，以及通过电极法（以1413 µS/cm标准溶液校准）测定的电导率、盐度与总溶解固体（TDS）含量。
