在活跃的海底喷口场周围进行了广泛的深拖调查，以绘制热液排放的三维分布图并计算热液和锰的热液排放。 10公里长的喷口场的排放物形成了约250米厚的近等重羽流，并沿当地净流方向拉长。点源和扩散源的热液排放净输出量是根据羽流的平流输送估算的；热通量为 5.8 × 2.9 x 108 瓦，溶解锰通量为每秒 0.2 × 0.1 摩尔。这种类型的通量测量可以扩展到涵盖整个山脊段，从而可以在公共空间尺度上与理论热和化学过程模型进行比较。
An extensive deep-tow survey around an active submarine vent field was conducted to map the three-dimensional distribution of hydrothermal emissions and calculate the hydrothermal discharge of heat and manganese. Emissions from the 10-kilometer-long vent field formed a nearly isopycnal plume about 250 meters thick and elongated in the direction of the local net current. Net export of hydrothermal discharge from both point and diffuse sources was estimated from the advective transport of the plume; the heat flux was 5.8 � 2.9 x 108 watts and the dissolved manganese flux was 0.2 � 0.1 moles per second. Flux measurements of this type could be expanded to encompass entire ridge segments, allowing comparison with theoretical thermal and chemical process models on a common spatial scale.
