Jie Chen (陈杰)

Ph.D. in Marine Geoscience

Laboratoire de Géologie, Ecole Normale Supérieure, PSL University

Welcome

My name is Jie Chen (陈杰). I’m now a postdoc at Laboratoire de Géologie, Ecole Normale Supérieure, PSL University. Before that, I was a postdoc at Marine Geosciences, Institut de Physique du Globe de Paris (IPGP), Universitè Paris Cité.

I use geomorphological (e.g., bathymetry, sidescan, and seafloor imagery), geophysical (e.g., gravity, magnetic, and seismicity) and numerical (e.g., thermal modelling) approaches to investigating seafloor spreading processes at the mid-ocean ridges. Recently, I focus on the thermal regime of the mid-ocean ridges using numerical modelling and faulting using high-resolution bathymetry collected by Autonomous Underwater Vehicle (AUV).

Looking into the Earth from multiple perspectives

Magmatism, tectonism, and segmentation of ultraslow spreading ridges

Ultraslow spreading ridges, which account for ~20% of the global Mid-Ocean Ridge (MOR) system, are the least surveyed part of the MOR system, because they are mostly in hard-to-access oceans. The longest (~7000 km), the Southwest Indian Ridge (SWIR), is in a remote location with the Roaring Forties, and the second longest (~2000 km), the Gakkel Ridge, is in the ice-covered Arctic Ocean.

Seafloor mapping with AUV-borne high-resolution bathymetry

AUV-borne high-resolution (HR) bathymetry data are revolutionizing our ability of seafloor mapping and hence our understanding of the Mid-Ocean Ridge (MOR) processes. HR bathymetry data provide great details in fine-scale fault systems with resolutions of 0.

Thermal regime of Mid-Ocean Ridges by numerical modelling

The thermal regime of the global Mid-Ocean Ridges (MOR) is a key control on the dynamics of seafloor spreading. It is typically assessed through numerical thermal models that balance a steady magmatic heat input with a hydrothermal output, rather than observational approaches alone.
