A Transient in Surface Motions Dominated by Deep Afterslip Subsequent to a Shallow Supershear Earthquake
The 2018 M<sub>w</sub>7.5 Palu Case
The 2018 (Formula presented.) Palu earthquake is a remarkable strike-slip event due to its nature as a shallow supershear fault rupture across several segments and a destructive tsunami that followed coseismic deformation. GPS offsets in the wake of the 2018 earthquake display a

A Tsunami Generated by a Strike-Slip Event
Constraints From GPS and SAR Data on the 2018 Palu Earthquake
A devastating tsunami struck Palu Bay in the wake of the 28 September 2018 Mw = 7.5 Palu earthquake (Sulawesi, Indonesia). With a predominantly strike-slip mechanism, the question remains whether this unexpected tsunami was generated by the earthquake itself, or rather by earthqu

Separating Geophysical Signals Using GRACE and High-Resolution Data
A Case Study in Antarctica
To fully exploit data from the Gravity Recovery and Climate Experiment (GRACE), we separate geophysical signals observed by GRACE in Antarctica by deriving high-spatial resolution maps for present-day glacial isostatic adjustment (GIA) and ice-mass changes with the least possible

Maintaining Tropical Beaches with Seagrass and Algae
A Promising Alternative to Engineering Solutions
Tropical beaches provide coastal flood protection, income from tourism, and habitat for flagship species. They urgently need protection from erosion, which is being exacerbated by changing climate and coastal development. Traditional coastal engineering solutions are expensive, p

A high resolution model of linear trend in mass variations from DMT-2
Added value of accounting for coloured noise in GRACE data
We present a high resolution model of the linear trend in the Earth’s mass variations based on DMT-2 (Delft Mass Transport model, release 2). DMT-2 was produced primarily from K-Band Ranging (KBR) data of the Gravity Recovery And Climate Experiment (GRACE). It comprises a time se

Estimating decadal variability in sea level from tide gauge records
An application to the North Sea
One of the primary observational data sets of sea level is represented by the tide gauge record. We propose a new method to estimate variability on decadal time scales from tide gauge data by using a state space formulation, which couples the direct observations to a predefined s

The sea-level budget along the Northwest Atlantic coast
GIA, mass changes, and large-scale ocean dynamics
Sea-level rise and decadal variability along the northwestern coast of the North Atlantic Ocean are studied in a self-consistent framework that takes into account the effects of solid-earth deformation and geoid changes due to large-scale mass redistribution processes. Observatio

This work provides a comparison of four approaches that can be used to describe uncertainty in models of the long-term glacial isostatic adjustment (GIA) process. The four methods range from pessimistic to optimistic representations of GIA uncertainty. Each estimation method is a

The global signature of post-1900 land ice wastage on vertical land motion
Melting glaciers, ice caps and ice sheets have made an important contribution to sea-level rise through the last century. Self-attraction and loading effects driven by shrinking ice masses cause a spatially varying redistribution of ocean waters that affects reconstructions of pa

Global sea-level budget 1993–present
WCRP Global Sea Level Budget Group
Global mean sea level is an integral of changes occurring in the climate system in response to unforced climate variability as well as natural and anthropogenic forcing factors. Its temporal evolution allows changes (e.g., acceleration) to be detected in one or more components. S

Closing the sea level budget on a regional scale
Trends and variability on the Northwestern European continental shelf
Long-term trends and decadal variability of sea level in the North Sea and along the Norwegian coast have been studied over the period 1958–2014. We model the spatially nonuniform sea level and solid earth response to large-scale ice melt and terrestrial water storage changes. GP

Predicting the impact of sea-level rise in Baie Orientale and Baie de L'Embouchure, Saint Martin
Application of a hydrodynamic model including seagrass and coral reefs
Shallow bays in the Caribbean, like Baie Orientale and Baie de L'Embouchure in Saint Martin, are often sheltered by coral reefs and covered by seagrass meadows. They provide valuable services as tourism and coastal protection. The ecosystems are linked through biological, chemica

Marine Cloud Brightening: How Sea Salt Aerosol Properties Relate to the Brightening Of Stratocumulus Clouds
Over the period 1901-2012, the average global sea surface temperature has increased by 0.89 °C due to climate change and it is expected to increase consistent with global warming. As a consequence, marine ecosystems have become more susceptible to change in species and ocean chem

Analysis of the Interannual Variability of the Amazon-Orinoco River Plume
And its effects on Sea Surface Temperatures in the Caribbean Sea
TheAmazon-Orinoco river plume is a buoyant freshwater lens of 1.2 × 106km2, which has been traced over 2000 km from the Amazon river mouthinto the Caribbean Sea and along the Lesser Antilles. The river plume iswarmer than the surrounding open-ocean waters, with temperaturediffere

Biogeomorphic modelling of tropical sheltered bays
Assessment of the role of seagrass ecosystems in tropical sheltered bays in the Caribbean
Coastal bays in the Caribbean accommodate different marine ecosystems, including seagrass meadows and coral reefs, which provide important ecosystem services. However, these marine ecosystems are endangered. Seagrass ecosystems have a key role in coastal bays, but despite their a

InSAR as a volcanic monitoring tool for Saba and St. Eustatius
A comparison of ALOS-2, Sentinel-1 and PAZ data
In this study an analysis of the efficacy of using satellite data, in the form of InSAR measurements, as an extension of the volcanic monitoring network on Saba and St. Eustatius is performed. For this research, data from three different satellites that operate at three different

Ocean Dynamics and Ice Fractures
Insights from Earth and Beyond
Ice, a pervasive element across the Solar System, holds immense importance in understanding the response of the Earth to ongoing climate change as well as the dynamics of planetary bodies. This dissertation investigates ice fractures on terrestrial and planetary ice bodies, focus

The Causes of Regional Sea-level Change
Since 1993
As a result of climate change, sea level is changing all over the world at unprecedented rates. Sea-level change can have significant impacts on coastal communities, infrastructure and global economy, as most of the major cities are located near to or at the coast. Rising sea lev

Detecting climate patterns
Bayesian neural network approach
Machine learning is becoming an increasingly important tool for climate scientists, but hampered by lacking uncertainty quantification. Here, a machine learning approach for detecting patterns indicating a changing climate is combined with probabilistic modelling to retrieve unce

Density driven flows, due to hurricanes
A case study of hurricane Irma and Maria around Saint Martin
In this report a first assessment is made of the impact of hurricanes on Saint Martin. Two bays at the east coast of Saint Martin, Baie Orientale and Baie de L'Embouchure, are studied under the conditions of hurricane Irma and Maria, which both have passed over in September 2017.
