As a master student at centre for ice and climate, you will work in an active and dynamic group on a real research project, possibly involving field work on the greenland ice sheet. Below you can find some older project suggestions, andt you are also very welcome to come by the centre and ask the researchers for further options or present your own idea that we can develop together. Five projects with a large variety of skills involving both work in the laboratory, development of new instrumentation and analysis of high resolution climate data. It is photochemically produced by oxidation of methane and non methane hydrocarbons nmhc. It is further a product of incomplete combustion from fossil fuel and biomass burning.

read full description at the link below. the master thesis has two aspects 1 measure the permeability of molecular hydrogen through natural ice. The goal is to clear the above mentioned questions before a field season in 2015 with the goal to recover ice from greenland for hydrogen measurements of the past atmosphere. Are you an experienced programmer in python, or would you like to develop your python programming skills? impurities in ice cores are often measured by a technique known as continuous flow analysis cfa , in which an ice core is slowly melted and the melt water is pumped to a range of impurity detector systems. Currently, the melt rate is monitored using a draw wire encoder attached to the ice, which produces electronic rdquo counts rdquo as the ice moves toward the melter.

An alternative method for measuring melt speed in cfa systems is by image recognition using image data to measure how fast the ice is moving. The aim of this project is to develop a python code which detects features on the surface of the ice, tracks them and calculates the ice core melting speed. Colourimetry may offer a way of achieving reliable, high resolution determination of sulphate concentrations in melted ice core samples. This project involves the investigation and implementation of the most efficient, sensitive and reliable means of producing a colourimetric reaction between sulphate ions and indicator dyes, and then evaluating and recording the signal. Predominantly chemistry and physics skills will be required, but the project will also involve interfacing optical spectrometers and software control programs.

The ratio between these isotopes bears climate information about biological processes. As the content of 17o is extremely low it is necessary to remove components other than o2 from an atmospheric sample to get reliable measurements. We are exploring new ways to separate o2 by means of a mixed ionic electronic ceramic membrane. Enormous amounts of ch4 are sitting on the ocean floor in the form of methane hydrates also called clathrates. The clathrate gun hypothesis speculates that a spontaneous release of methane from clathrates increases the atmospheric methane composition to the degree where the boosted greenhouse effect triggers climate change. The master thesis project involves extending our measurement capacities to isotopes of hydrogen, testing the new system, and performing first measurements over a climatologically interesting time period.

In recent years, laser based instruments has shown huge advances in application to trace gas isotope and concentration measurements. First conceptual interpretation of the measured variations of the n2o isotopomers. So far there exists no record of the northern hemispheric co history reaching back more than a few years. Our project is to measure accurately concentration and isotope ratios of co in the firn column in northern greenland to reconstruct the recent co history. Long ice core records of sulphate can be used to reconstruct past volcanic activity.

An important method to obtain highly depth resolved sulphate data from ice cores is the continuous flow analysis cfa technique. The goal of this experimental master thesis project is to develop, characterize and apply a new cfa module to measure fluoride in greenland ice core samples. Deep drilling project: ecm the electrical conduction is mainly due to high concentrations of ions in the ice from past major volcanic eruptions. The detection of the volcanic signals, their chemical concentrations and frequency are important climate parameters but can also be used to transfer the time scales between ice cores. The aim of this project is to further develop equipment to measure the electrical properties ecm of the ice along the ice cores. The master project is within climate research and has the potential to lead to cutting edge ice core research. When snow is compressed to ice, crystals are formed with nearly random orientation.

As the ice is further compressed and moves down in the ice sheet the ice crystals grow and the crystal orientation is influenced by ice deformation. The aim of this project is to measure the crystal size and orientation with depth. The results can be used to understand and develop anisotopic deformation laws for ice. you write your master rsquo s thesis as the last part of your education and for that reason many students choose a topic that summarises the choices and specialisations that have shaped their education.

Some choose a very specific and confined topic, while others collaborate with businesses. There are many options and the choice is yours. always remember that you must enter into a master rsquo s thesis contract, when you start working on your thesis. You are supposed to be able to complete your work, from idea to finished thesis, in 6 months, and the teachers know this and adjust their expectations accordingly. The purpose of the rules is that thesis work must be completed within the prescribed period. As a student in the department you are subject to the faculty rsquo s common rules regarding theses. Choosing your supervisor when you are about to start work on your thesis you need a supervisor first and foremost. Often, students will find a supervisor who has an academic knowledge of the topic they are writing about, but at the same time it is important that you get along well with your supervisor and that you have good chemistry.

Often you will need to do some mental balancing and find out what you expect your supervisor to help you with. If you need academic mentoring then, of course, it is important that the supervisor has some knowledge of your topic. But if you primarily need a process supervisor, he or she may not necessarily need a particular academic insight into your thesis topic. You must apply to the board of studies for the allocation of a master rsquo s thesis supervisor, and based on your application they will try to find the best possible supervisor for you. On the application form you must very briefly outline the topic of your thesis and indicate what you expect a supervisor to help you with. You can make suggestions for supervisors in order of priority but the board of studies cannot guarantee that you will be allocated any of the supervisors you have suggested.

If, contrary to expectations, the collaboration with your supervisor does not work, you can apply for another supervisor with the board of studies. A change of supervisor does not warrant an extension of the contract, so for your own sake you should react quickly if you find that something is not right. This number of hours include the supervisor rsquo s preparation for your meetings but not his or her final evaluation. In some programmes it is possible to collaborate with business on your thesis work or to include a practical dimension. Often, special rules apply to these kinds of theses, so you should consult your curriculum, if you wish to compose such a thesis. Feel free to contact your student guidance counsellor if you are unsure of the rules.

Theses are submitted at the department either to the study secretaries or one of the exam secretaries. These can only be handed in once a month, which is the first weekday working day of each month. If you submit your thesis at any other time, it will not be registered until the first weekday working day of the following month. The specialization in political theory concludes with an 80 page long master rsquo s thesis on a topic chosen by the student. Recent thesis titles include: a decision in dispute: the democratic legitimacy of the danish parliament's decision to send a military contribution to the 2003 invasion of iraq. Cyberspace: a dispositive analysis of the sovereign territorial connotations of the metaphor and their consequences for international regulation of the cyber field.
