We use co-located CTD/transmissometry casts and multichannel seismic reflection surveys conducted at the Costa Rica Rift (CRR) to provide a better understanding of magma-hydrothermal processes occurring at an intermediate-rate spreading center. Water... Read More about Magma-hydrothermal interactions at the Costa Rica Rift from data collected in 1994 and 2015.

Constraining the maximum depth of brittle deformation at slow- and ultraslow-spreading ridges using microseismicity (2019)
Journal Article
Grevemeyer, I., Hayman, N., Lange, D., Peirce, C., Papenberg, C., Van Avendonk, H., …Dannowski, A. (2019). Constraining the maximum depth of brittle deformation at slow- and ultraslow-spreading ridges using microseismicity. Geology, 47(11), 1069-1073. https://doi.org/10.1130/g46577.1

The depth of earthquakes along mid-ocean ridges is restricted by the relatively thin brittle lithosphere that overlies a hot, upwelling mantle. With decreasing spreading rate, earthquakes may occur deeper in the lithosphere, accommodating strain with...

Constraints on crustal structure of adjacent OCCs and segment boundaries at 13N on the Mid-Atlantic Ridge (2019)
Journal Article
Peirce, C., Reveley, G., Simao, N., Robinson, A., Funnell, M., Searle, R., …Reston, T. (2019). Constraints on crustal structure of adjacent OCCs and segment boundaries at 13N on the Mid-Atlantic Ridge. Geophysical Journal International, 217(2), 988-1010. https://doi.org/10.1093/gji/ggz074

The 13° N segment of the Mid-Atlantic Ridge is an example of a morphologically well-studied slow spreading ridge segment populated with oceanic core complexes (OCCs). In this paper we present the results of a ∼200 km-long 2D seismic and gravity trans...
