Global warming arises from an energy imbalance where increased radiative forcing from greenhouse gases traps additional heat in the Earth system. Over recent decades, more than 90% of this heat has gone into the ocean, causing thermal expansion that leads to sea level rise. Addi…

Maps and models of seismic and tsunami risk are constructed from a variety of measurements taken in Indonesia, which have the potential to reduce loss of life and infrastructure. The first study uses the multichannel analysis of surface waves (MASW) method to calculate the time-…
This thesis presents a multi-proxy reconstruction of Holocene sea-level change at the Steart Peninsula in Bridgwater Bay, Somerset. Single- and multi-proxy transfer functions were developed from diatom and foraminifera training data from two sites on the Severn Estuary coast. Co…
This work examines the use of pedo-properties to identify dune soil system responses to environmental change on the Sefton coast, based on the development of conceptual pedogenic models. Previous environmental change and shoreline dynamics are determined through O.S. maps and ae…
The tectonic opening and closing of ocean gateways played a key role in global climate change during the Cenozoic. Although changes in these gateways affected ocean circulation and heat transport, many of their paleoceanographic effects are still unknown. This dissertation exami…
Monthly mean sea levels in the Arabian Sea have been investigated for seasonal-to-annual variation and interannual oscillations. Relative Sea level in the Port of Aden is rising either due to the widening sea floor and/or to volume changes caused by thermal expansion. However, a…
Glacial isostatic adjustment (GIA) is the ongoing response of the viscoelastic solid Earth, oceans and the gravitational field to the previous burden of the ice loads. The Earth’s surface was once covered with massive ice sheets, and melting of these ice sheets is still reshapin…
Until now, works in the field of tide routing (i.e., optimization of cargo loading and ship scheduling decisions in tidal ports and shallow seas) have omitted the uncertainty of sea level predictions. However, the widely used harmonic tide forecasts are not perfectly reliable. C…
A ocorrência de cheias e inundações constitui uma problemática de cariz global associada a inúmeras e nefastas repercussões na sociedade.
This dissertation presents results from the use of geophysical methods to study conditions beneath glaciers, including bed physical properties, topography, melting, and water flow. Chapter 1 briefly reviews the history of study and importance of Thwaites Glacier (TG), West Antar…
The Giant Foresets Formation in the Taranaki Basin defines the present-day continental margin of the west coast of New Zealand’s North Island. Using regional 2D and 3D seismic datasets calibrated with exploration wells, this thesis presents a new highresolution seismic stratigra…
