PhD Position Historical Changes of Antarctic Glaciers from Photogrammetry TU Delft






PhD Position Historical Changes of Antarctic Glaciers from Photogrammetry TU Delft


Job description
The Antarctic Peninsula is one of the fastest changing regions on our planet, and experienced a warming unparalleled anywhere else in the Southern Hemisphere in the late-20th century. Several ice shelves along its margins have retreated or disintegrated, leading to rapid changes of the glaciers on its mainland. Due to its relatively small scale and complex topography, a detailed picture of the mass balance of the region was missing until the recent advent of high-resolution satellite observations. While these data revealed that the Peninsula is losing ice rapidly, a long-term perspective of the changes is still lacking.
In this project, you will unlock the potential of a vast archive of aerial photographs, obtained by the U.S. Navy since the 1940s, along ten thousands of kilometers spanning the Antarctic continent. Using the overlap between consecutive acquisitions in a Structure from Motion photogrammetry approach - combined with recent developments in high performance computing and image pattern recognition - you will derive digital elevation models of the Antarctic Peninsula, dating back more than five decades. These models will be compared to present-day elevation data, for example from satellite photogrammetry and LiDAR altimetry (ICESat-2), to obtain a detailed picture of elevation and mass changes over the past 50 years. Furthermore, regional climate models will be used to put the observed changes in a broader climatological perspective.
Your work will provide a unique insight into the long-term impact of changing climate conditions on Antarctica's glaciers, and their dynamical response to ice shelf weakening and disintegration. Your results will provide essential validation data for ice modelling efforts, thereby contributing to reducing the uncertainties in future sea level rise scenarios.
We aim to start the project early 20201, but no later than March, 1, 2021. During the project you will be supervised by Bert Wouters and Roderik Lindenbergh at TU Delft and you will collaborate with researchers at Utrecht University and in Norway, France and USA. If the situation allows, your project will include a research visit to one of our international collaborators.
Department
The position is located within the department of Geoscience and Remote Sensing (GRS). We seek to advance the understanding of dynamic processes on—and human interaction with—Earth, with a focus on atmospheric sciences and geodesy. The approach is based on the development of observation technology as well as the modelling of processes.

Geography of Landslides. Mitigation and Resilience.

A landslide is a geological event in which a mass of rock, earth, or debris moves down a slope under the force of gravity. Landslides can range in size from small to large and can be triggered by natural events such as heavy rainfall, earthquakes, or volcanic activity, or by human activities such as construction or mining. The geography of landslides is affected by a variety of factors that can increase the likelihood of landslides occurring in a particular area. These factors include slope angle and steepness, the type of soil and rock present, the climate and weather patterns of the region, the presence or absence of vegetation, and human activities such as construction, mining, and deforestation. Areas with steep slopes are more prone to landslides because gravity has a stronger effect on loose soil and rock, making it more likely to move downhill. Similarly, areas with loose, sandy soil or weak, fractured rock are more prone to landslides because they are less stable and more easil

Landslide

Landslides are a type of "mass wasting," where soil and rock move down-slope due to gravity. Landslides can be caused by a combination of factors, such as rainfall, snowmelt, changes in water level, and human activities. There are five modes of slope movement, including falls, topples, slides, spreads, and flows, which vary depending on the type of geologic material. Debris flows and rock falls are common types of landslides. Landslides can also occur underwater, known as submarine landslides, and sometimes cause tsunamis. Landslides occur when down-slope forces exceed the strength of the earth materials that compose the slope. Slopes already on the verge of movement are more susceptible to landslides, which can be induced by earthquakes, volcanic activity, and stream erosion.  There are four main types of movement: falls, topples, slides (rotational and translational), and flows. Landslides can involve just one of these movements or a combination of several. Geologists also

Disaster Management Act, 2005. National Disaster Management Framework (NDMF) National Disaster Management Authority (NDMA). National Institute of Disaster Management (NIDM). National Disaster Response Force (NDRF) The National Disaster Management Framework (NDMF) in India is a comprehensive policy document that provides a framework for managing disasters in the country. The framework was first introduced in 2005 and was updated in 2019. The NDMF is based on the principle of an integrated approach to disaster management. It aims to bring together all stakeholders, including the government, non-governmental organizations (NGOs), civil society, and the private sector, to work towards a common goal of disaster management. The framework is designed to address all phases of disaster management, including prevention, preparedness, response, and recovery. It provides guidelines for various aspects of disaster management, including risk assessment, disaster planning, early warning systems, sear

Disaster Management. Geography of Disaster Management.

Disaster management refers to the process of preparing for, responding to, and recovering from disasters or emergencies that may affect communities, regions, or entire countries. It involves the coordination of various activities and efforts by government agencies, non-governmental organizations, and other stakeholders to minimize the impact of disasters and promote the well-being of affected populations. The process of disaster management can be broken down into four phases: Mitigation: This involves taking steps to reduce the risk of disasters, such as identifying and addressing potential hazards, developing emergency plans, and improving infrastructure and systems. Preparedness: This involves preparing for the possibility of a disaster, such as training emergency responders, conducting drills and exercises, and stockpiling necessary supplies. Response: This involves taking immediate action during and immediately after a disaster, such as rescuing people, providing emergency medical

Earthquake. Terminology and Concept

Earthquake It is a transient violent movement of the Earth's surface that follows a release of energy in the Earth's crust. 2. Magnitude It is a measure of the amount of energy released during an earthquake and expressed by Richter scale. Effect of earthquake according to Richter scale . Richter Magnitude Earthquake effects Less than 3.5 Generally not felt, but recorded. 3.5-5.4 Often felt, but rarely causes damage. Under 6.0 At most, slight damage to well-designed buildings. Can cause major damage to poorly constructed buildings over small regions. 6.1-6.9 Can be destructive in areas up to about 100 across where people live. 7.0-7.9 Major earthquake. Can cause serious damage over larger areas. 8 or greater Great Earthquake. Can cause serious damage in areas several hundred across. 3.
