Cruise Inventory Information
| Long name | Sonne cruise SO238 |
|---|---|
| Short name | SO238 |
| Objectives and Narrative |
The cooling of young oceanic crust is the main physical process responsible for removing heat from the solid Earth to the hydrosphere. Close to the mid-ocean ridges, rapid cooling is dominated by hydrothermal circulation of seawater through the porous and fractured basalt crust. This hydrothermal fluid is then discharged into the ocean mainly along the ridges. The cruise SO238 is part of an interdisciplinary project to investigate the effects of this heat loss and hydrothermal circulation in both the solid Earth and the ocean. The data collected during the cruise will allow us to derive an integrated model which will be constrained by geophysical, geological and physical oceanography data that includes pathways in both the solid Earth and the ocean including fluxes through the seabed.
The cruise was divided into three stages. During the first part of the cruise, a 2-ship synthetic aperture multichannel seismic reflection survey over three 270-km transects was carried out to map the evolution of crust structure, properties and morphology along the southern flank of the Costa Rica Ridge. The lead ship for this work was RRS James Cook, with FS Sonne trailing 9 km behind. In the second part of the cruise, we recovered a line of three moorings equipped with current meters, CTD (Conductivity, Temperature, Depth) sensors, bottom pressure recorders (BPRs) and 12 magnetotelluric landers that were deployed in December 2014 from RRS James Cook (cruise JC112). In the final part of the cruise, we deployed an ADCP mooring for 24 hours to monitor flows across the Ecuador Trench, southeast of the Costa Rica Ridge and, subsequently, carried out a series of ~40 CTDs in the eastern half of the Panama Basin.Swath bathymetry was collected throughout the cruise. |
