资源简介：
The Middle America Trench was first drilled in 1979 during Leg 66 off Oaxaca, Mexico and Leg 67 off Guatemala as part of a broad effort to study the mechanics of plate subduction and continental accretion and erosion. Leg 84 was recommended by the JOIDES Advisory Panels specifically to further examine the tectonic and gas-hydrate problems which had been revealed in the previous survey.
