Digital holographic microscope recordings of passive motion of small particles

Christian Lindensmith, Jay Nadeau & Devan Rouzie
Digital holographic microscopy provides the ability to observe throughout a volume that is large compared to its resolution without the need to actively refocus to capture the entire volume. This enables simultaneous observations of large numbers of small objects within such a volume. We have constructed a microscope that can observe a volume of 0.4 x 0.4 x 1.0 µm with submicrometer resolution (in xy) and 2 µm resolution (in z) for observation of microorganisms...

Surface deformation associated with fractures near the 2019 Ridgecrest earthquake sequence

Xiaohua Xu, David T. Sandwell, Lauren A. Ward, Chris W. D. Milliner, Bridget R. Smith-Konter, Peng Fang & Yehuda Bock
Contemporary earthquake hazard models hinge on an understanding of how strain is distributed in the crust and the ability to precisely detect millimeter-scale deformation over broad regions of active faulting. Satellite radar observations revealed hundreds of previously unmapped linear strain concentrations (or fractures) surrounding the 2019 Ridgecrest earthquake sequence. We documented and analyzed displacements and widths of 169 of these fractures. Although most fractures are displaced in the direction of the prevailing tectonic stress (prograde),...

Physical processes controlling the rifting of Larsen C Ice Shelf, Antarctica, prior to the calving of iceberg A68 in 2017

Eric Rignot, Eric Larour, Bernd Scheuchl & Mattia Poinelli
The sudden propagation of a major pre-existing rift (full-thickness crack) in late 2016 on the Larsen C Ice Shelf, Antarctica lead to the calving of tabular iceberg A68 in July 2017, one of the largest icebergs on record, posing a threat for the stability of the remainder of the ice shelf. As for other ice shelves, the physical processes that led to the activation of the A68 rift and controlled its propagation have not been...

Data from: Widespread grounding line retreat of Totten Glacier, East Antarctica, over the 21st century

Tyler Pelle, Mathieu Morlighem, Helene Seroussi & Yoshihiro Nakayama
Totten Glacier, the primary ice discharger of East Antarctica, contains 3.85 m sea level rise equivalent ice mass (SLRe) and has displayed ocean-driven dynamic change since at least the early 2000s. We project Totten’s evolution through 2100 in a fully coupled ice-ocean model, forced at the ocean boundaries with anomalies in CMIP6 projected temperature, salinity, and velocity. Consistent with previous studies, the Antarctic Slope Current continues to modulate warm water inflow towards Totten in future...
