This project will determine the thermal budget of oceanic crustal formation using measurements of vertical heat flux on the Endeavour segment of the Juan de Fuca Ridge by systematically surveying areas of diffuse hydrothermal venting within the axial valley using meters. The detailed measurements of near-bottom vertical heat flux will allow determination of the horizontal dimensions of the crustal fluid circulation cells, identification of recharge zones, and the partitioning of the heat of crustal formaiton between focused high-temperature vents, diffuse flow and conductive heat flux.

该项目将通过使用米米在轴向山谷内的弥漫性水热通风板系统地测量轴向水热通风的区域来确定海洋地壳形成的热预算。 近底垂直热通量的详细测量将允许确定地壳流体循环细胞的水平尺寸，鉴定充值区域以及在聚焦的高温通风孔，弥漫性流动和导电热量之间的地壳官方热量分配。
