In this paper, we use SLR data tracked by the ILRS network over the last twenty years to derive time series of Earth Orientation Parameters, as well as time series of low wavelengths of the Earth's gravity field. The work is based on post-fit residuals analyses, performed with the stacking of weekly-orbital arcs of the constellation of geodetic...

Decades of cruise-based exploration have provided excellent snapshots of the structure of mid-ocean ridges and have revealed that accretion is a mixture of steady-state and quantum events. Observatory-type studies are now needed to quantify the temporal evolution of these systems. A multi-disciplinary seafloor observatory site is currently...
