Journal Article
Yang, P., Welford, J. K., Peace, A. L., & Hobbs, R. (2020). Investigating the Goban Spur rifted continental margin, offshore Ireland, through integration of new seismic reflection and potential field data. Tectonophysics, 777, Article 228364. https://doi.org/10.1016/j.tecto.2020.228364

The Goban Spur, offshore Ireland, is a magma-poor rifted continental margin conjugate to the well-studied Newfoundland margin, offshore Canada. Published studies demonstrated that a 70-km-wide zone of exhumed serpentinized mantle lies between oceanic...

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.

Detecting changes at the leading edge of an interface between oceanic water layers (2019)
Journal Article
Tang, Q., Tong, V. C., Hobbs, R. W., & Morales Maqueda, M. Á. (2019). Detecting changes at the leading edge of an interface between oceanic water layers. Nature Communications, 10(1), Article 4674. https://doi.org/10.1038/s41467-019-12621-8

Many physical phenomena in the ocean involve interactions between water masses of different temperatures and salinities at boundaries. Of particular interest is the characterisation of finescale structure at the marginal interaction zones of these bo...

A lower to middle Eocene astrochronology for the Mentelle Basin (Australia) and its implications for the geologic time scale. Earth and Planetary Science Letters, 529, Article 115865. https://doi.org/10.1016/j.epsl.2019.115865

The geologic time scale for the Cenozoic Era has been notably improved over the last decades by virtue of integrated stratigraphy, combining high-resolution astrochronologies, biostratigraphy and magnetostratigraphy with high-precision radioisotopic...

Journal Article
Wainman, C., Borissova, I., Harry, D., Hobbs, R., Mantle, D., Maritati, A., Lee, E., & Scientists, T. E. 3. (2020). Evidence for non-marine Jurassic to earliest Cretaceous sediments in the pre-breakup section of the Mentelle Basin, southwestern Australia. Australian Journal of Earth Sciences, 67(1), 89-105. https://doi.org/10.1080/08120099.2019.1627581

The Mentelle Basin, located off the southwestern continental Australian margin, is an under-explored deep-water basin that developed during the breakup of eastern Gondwana in the Middle Jurassic through to the Early Cretaceous. There is a high degree... Read More about Evidence for non-marine Jurassic to earliest Cretaceous sediments in the pre-breakup section of the Mentelle Basin, southwestern Australia.

Evolution of Heat Flow, Hydrothermal Circulation and Permeability on the Young Southern Flank of the Costa Rica Rift (2019)
Journal Article

We analyze 67 new conductive heat flow measurements on the southern flank of the Costa Rica Rift (CRR). Heat flow measurements cover five sites ranging in oceanic crustal age between approximately 1.6 and 5.7 Ma, and are co-located with a high-resolu...

Geochronology is essential for understanding Earth’s history. The availability of precise and accurate isotopic data is increasing; hence it is crucial to develop transparent and accessible data reduction techniques and tools to transform raw mass sp...

The Panama Basin serves as a laboratory to investigate abyssal water upwelling. The basin has only a single abyssal water inflow pathway through the narrow Ecuador Trench. The estimated critical inflow through the Trench reaches 0.34 ± 0.07 m s−1, re... Read More about Geothermal heating in the Panama Basin. Part I: hydrography of the basin.
