This award will support a research collaboration between a group headed by Prof. John Sclater of the Scripps Institution of Oceanography and Prof. Ricardo Fernandez of the Centro de Investigacion Cientifica y Educacion Superior de Ensenada (CICESE) of Mexico. The purpose of the collaboration is to study the relation between heat flow and depth in the Gulf of Mexico. The old ocean floor of the western Gulf of Mexico has the lowest heat flow observed through oceanic crust. Most researchers have ignored these data, which was collected in the 60's, attributing the low values to unusually rapid sedimentation or to non-linear thermal gradients. However, a re-analysis of much of the data suggests that the role of non-linear gradients has been exaggerated and that much of the data may be reliable. For this project, the investigators intend to carry out detailed heat flow surveys around two sites in the Gulf of Mexico, make individual measurements on a transect between the two sites, analyze these data, and determine whether it supports the thermal boundary layer model indicated by the earlier measurements.

该奖项将支持由斯克里普斯海洋研究所的John Sclater教授和墨西哥CICESE的Cientifica y Education Superior de Ensenada(CICESE)的Ricardo Fernandez教授领导的研究小组之间的研究合作。合作的目的是研究墨西哥湾热流和深度之间的关系。墨西哥湾西部的旧洋底是通过洋壳观察到的最低热流。大多数研究人员忽略了这些收集于60年代S的数据，将低值归因于异常快速的沉积或非线性的温度梯度。然而，对许多数据的重新分析表明，非线性梯度的作用被夸大了，许多数据可能是可靠的。对于这个项目，调查人员打算在墨西哥湾的两个地点周围进行详细的热流调查，在两个地点之间的横断面上进行单独测量，分析这些数据，并确定其是否支持由先前测量所指示的热边界层模型。
