Project proposal details
Please look carefully through the proposal details below. If you are interested in the project then contact the supervisor, explaining why you are interested and any background which makes you a good fit for the project.
If this is an external project, the lead supervisor may have suggested someone at Imperial College or the NHM who could act as an internal supervisor and you should also contact them. If the project is external and no internal has been proposed then you must find an internal supervisor before starting the project.
Please pay close attention to any extra notes on requirements (such as being able to drive or to speak particular languages) or the application process. There may be specific limitations on the project availability: if there are then they will be clearly shown further down the page.
Land versus lake temperatures: modelling the influence of climate changes on the habitat of aquatic plants and animals
Project based at
Silwood Park (Imperial)
his project is an opportunity to solve another conundrum about Holocene climate change in Europe, and how organisms responded to it. During the early Holocene, ca 10,000 years ago, the Scandinavian ice sheet had disappeared and most of northern Europe was forested. But there was still ice over North America, and climate models suggest that the resulting atmospheric circulation pattern caused cold summer conditions “downwind” across northern Europe. The composition of the forests (dominated by Betula, Pinus and other cold-tolerant genera) seems to agree. Yet at the same time, warmth-requiring aquatic plants (including the water chestnut, Trapa natans) and animals (including the European pond tortoise, Emys orbicularis) occurred far to the north of their present ranges. This apparent disparity between land and lake temperatures was noted more than half a century ago – long before modern computational methods were available to analyse such problems quantitatively. The project will model lake temperatures (using a widely used one-dimensional lake model, FLAKE) in combination with climate model outputs from the Palaeoclimate Modelling Intercomparison Project. It will test the hypothesis that lake temperatures were high due to the Earth’s early Holocene orbital configuration (July perihelion and high obliquity leading to enhanced solar radiation), while land temperatures were cooled by advection over the cold North Atlantic.
Project proposal limitations
The project proposer has indicated that there are some limitations to the availability of this project. It may only be available at certain times of year or suit a specific project length. It may also need skills taught to students on a particular course or courses.
Research project proposals are usually part of an active research programme. If supervisors have stated limitations to a proposal, then they are unlikely to have any flexibility. If you are very interested in the topic but have problems with the stated limitations, the supervisor may still be happy to talk to you about other options around the proposal, but you should not expect that any alternative arrangements can be made.
