DOI: 10.1002/2017jc012962
Abstract: The classic model of fjord renewal is complicated by tidewater glacier fjords, where submarine melt and subglacial discharge provide substantial buoyancy forcing at depth. Here we use a suite of idealized, high-resolution numerical ocean simulations… read more here.

DOI: 10.1016/j.coldregions.2018.03.003
Abstract: Abstract In this work we propose a method of estimating the age of calving events of a tidewater glacier based on 3D point clouds. Terrestrial LiDAR scans of the calving front of Fuerza Aerea Glacier… read more here.

DOI: 10.1017/aog.2023.38
Abstract: Frontal ablation, the combination of submarine melting and iceberg calving, changes the geometry of a glacier's terminus, influencing glacier dynamics, the fate of upwelling plumes and the distribution of submarine meltwater input into the ocean.… read more here.

DOI: 10.1017/jog.2017.69
Abstract: ABSTRACT We evaluate the variability in basal friction for Kronebreen, Svalbard, a fast-flowing tidewater glacier. We invert 3 years (2013–15) of surface velocities at high temporal resolution (generally 11 days), to estimate the changing basal… read more here.

DOI: 10.1029/2019jf005359
Abstract: Sedimentary processes are known to help facilitate tidewater glacier advance, but their role in modulating retreat is uncertain and poorly quantified. In this study we use repeated seafloor bathymetric surveys and satellite‐derived terminus positions from… read more here.

Abstract: Underwater melting How fast does warm ocean water melt glaciers that terminate in the sea? That question is central to understanding how fast ice sheets may lose mass, and thus how fast sea level will… read more here.
