Abstract
Passive microwave satellite observations are used to identify the presence of surface meltwater across Antarctica at daily intervals from July 1979 to June 2020, with a focus on ice shelves. Antarctic Peninsula ...

This thesis explores parts of the Hoop area in the southwestern Barents Sea using the TGS16004 3D seismic volume provided by VBPR and TGS Nopec Geophysical Company ASA. The survey is captured using the P-cable surveying ...

Open-ocean polynyas effectively couple the ocean and atmosphere through large ice-free areas within the sea-ice cover, release vast quantities of oceanic heat, and impact deep ocean ventilation. Changes in polynya activity, ...

Abstract The geometric properties of fractures influence whether they propagate, arrest, or coalesce with other fractures. Thus, quantifying the relationship between fracture network characteristics may help predict fracture ...

The spatial distribution of the geochemical domains hosting recycled crust and primordial (high-3He/4He) reservoirs, and how they are linked to mantle convection, are poorly understood. Two continent-sized seismic anomalies ...

In the winter, orographic precipitation falls as snow in the mid to high latitudes where it causes avalanches, affects local infrastructure, or leads to flooding during the spring thaw. We present a technique to validate ...

The formation of a global network of plate boundaries surrounding a mosaic of lithospheric fragments was a key step in the emergence of Earth’s plate tectonics. So far, propositions for plate boundary formation are regional ...

Abstract This chapter describes large-scale mantle flow structures beneath Antarctica as derived from global seismic tomography models of the present-day state. In combination with plate reconstructions, the time-dependent ...

The Earth’s mantle transition zone (MTZ), located between approximately 410-660 km depth, can store an amount of water equivalent to 2-10 oceans of water, which is transported into the deep mantle by subducting oceanic ...

Distributed Acoustic Sensing (DAS) involves the transmission of laser pulses along a fiber-optic cable. These pulses are backscattered at fiber inhomogeneities and again detected by the same interrogator unit that emits ...
