Heat flow measurements on METEOR cruise M86/5@en

Mud volcanoes (MV) are sources of mass and energy, transported from deeper levels of the sediment pile to the surface. Together with fluid and gas, thermal energy is emitted through these structures. Therefore heat flow determination is a sensible tool to detect and quantify the amount of convective flow. In the Gulf of Cadiz several mud volcanoes can be found along major tectonic lines (SWIM faults). We employ geothermal measurements to observe the activity of mud volcanoes and possible leakage at the faults apart from pronounced structures.泥火山（Mud volcanoes, MV）是物质与能量的运移源，可将沉积物柱深层的物质与能量输送至地表。这类构造在排出流体与气体的同时，还会释放热能。因此，热流测定是探测并量化对流热流规模的可靠手段。在加的斯湾（Gulf of Cadiz），沿主要构造线（SWIM断裂带）分布有多座泥火山。除了这类特征明显的构造体之外，我们还借助地热测量手段，观测泥火山的活动状态以及断裂带处可能存在的渗漏现象。
