Heat‐flow in the Caribbean is poorly known and generally low in the major basins and the Greater Antilles arc, but with some high values in active zones, like in the Cayman trough or in the Lesser Antilles Arc. Here we present new heat‐flow data for offshore Haiti, which is part of the Greater Antilles arc. We obtain new heat‐flow estimates from in situ measurements and Bottom Simulating Reflector (BSR). Both methods suggest a regionally low heat‐flow, respectively 46 ± 7 and 44 ± 12 mW/m², with locally high values exceeding 80 mW/m². The high heat‐flow values are generally located near faults, and could be related to fluid circulations. Our study confirms a low heat‐flow pattern at the scale of the Caribbean but points out the existence of local‐scale variability with high heat‐flow along the northern faults of the Caribbean region.

加勒比板块海地近海热流量估算

加勒比海的热流知之甚少，在主要盆地和大安的列斯群岛弧中普遍较低，但在活跃区，例如在开曼海槽或小安的列斯群岛弧中，热量的流量较高。在这里，我们提供了海地近海的新热流数据，这是大安的列斯群岛的一部分。我们可以通过现场测量和底部模拟反射器（BSR）获得新的热流估算值。两种方法均表明区域内的热流较低，分别为46±7和44±12 mW / m ²，局部高热值超过80 mW / m ²。高热值通常位于断层附近，可能与流体循环有关。我们的研究证实了加勒比海地区的低热流模式，但指出了加勒比海地区北部断层热流较高的局部尺度变化。
