Hydrothermal circulation in the upper part of the igneous (volcanic) seafloor feeds submarine hot springs that support vigorous biological communities and causes an exchange of chemical elements between the rocks and sea water the affects the chemistry of the oceans in important ways, yet understanding these hydrothermal systems has been hampered by the difficulty of measuring heat flow and fluid flow. Heat flow blankets developed by one of the proponents of this projects are designed for deployment on bare rock, and thus hold the potential of providing improved and more detailed heat flow values. This deployment of heat flow blankets in combination with magnetic gradiometer and high-resolution bathymetry data seeks to characterize hydrothermal circulation at the RAVEN in detail. In additional to developing a heat flow method and contribution important new data to the field, broader impacts of this work include student participation, and outreach through teaching and public lectures.

火成岩（火山）海底上部的热液循环为海底温泉提供养分，这些温泉支持着生机勃勃的生物群落，并导致岩石和海水之间的化学元素交换，从而以重要方式影响海洋的化学性质，但由于难以测量热流和流体流动，对这些热液系统的了解一直受到阻碍。由该项目的一个支持者开发的热流毯是为在裸岩上部署而设计的，因此有可能提供更好和更详细的热流值。这种热流毯的部署与磁梯度仪和高分辨率测深数据相结合，旨在详细描述RAVEN的热液循环。除了开发热流方法并为该领域贡献重要的新数据外，这项工作的更广泛影响包括学生参与以及通过教学和公开讲座进行宣传。
