Link: http://www.awi.de/de/aktuelles_und_presse/stellenangebote/potsdam_berlin/.
Project: The PhD student will work within the joint Helmholtz-Russia Research Group "Assessing the Sensitivity of Arctic Coastal Dynamics". This bilateral project (with Helmholtz Center Geesthacht, Moscow State University, Melnikov Permafrost Institute of Yakutsk and Nansen International Environmental and Remote Sensing Center of Saint Petersburg) studies the environmental forcing of changing coastal morphology, mass flux in the near-shore zone and their controls on subsea permafrost. The project aims at recovering data of modern processes in the Siberian Arctic and modelling future changes as a reaction on global warming. The relevant research in Potsdam includes GIS-based, geophysical and modelling approaches. The PhD project will be supervised by project leaders P.P. Overduin and S. Wetterich at AWI Potsdam.

Tasks of the PhD student: Incremental development of conceptual and numerical models of permafrost evolution during marine transgression, coastal erosion and inundation based on appropriate input data.

Requirements: The position requires a diploma or master in Natural Sciences, preferably in the geosciences and/or physics. Experience in GIS and/or numerical modelling is required. Participation in field campaigns in the Arctic is possible but not a requirement for the position. Good knowledge of English and Russian (written and spoken) is of advantage.

A PhD position within Regional Climate Modelling of the Antarctic Peninsula is available at the Institute for Marine and Atmospheric research Utrecht (IMAU), Utrecht University, The Netherlands. See:
http://www.projects.science.uu.nl/imau/project1.html.

Job description:
IMAU is looking for a motivated PhD student (m/f) to study melt fluxes on the Antarctic Peninsula (AP) in relation to climate change. The AP is a region of fast atmospheric warming (three to four times the global average during the last five decades). The increased temperatures have led to increased melt water fluxes, which presumably have led to the disintegration of numerous ice shelves in the northern AP.

Aim of this project is to estimate how much melt presently occurs on the AP glaciers and ice shelves, and to study the importance of the process of refreezing with respect to runoff. Emphasis of the project will be on recent climate changes and ice shelf stability. A modelling and observational approach will be taken. A regional climate model will be used to estimate the melt over the past 50 years, where the observations will be used to validate the model output.

The candidate will be offered the opportunity to do fieldwork.

This work is performed in the framework of the Dutch Polar Program (NWO-ALW, NPP-NAAP).

The application deadline is 18th July 2011.

THE NORWEGIAN POLAR INSTITUTE is Norway's main institution for research, environmental management and monitoring, mapping and field work in the polar regions. The Institute is under the auspices of the Ministry of the Environment and is a contact and service body for national and international polar research. The NPI has currently expanded its activity due to additional tasks and an increased number of projects - especially within the field of climate change. The Institute encompasses 160 employees in Troms? (headquarters), in Svalbard (Spitsbergen) and in Antarctica.

Postdoctoral Research Fellow in Ocean Acidification processes in Arctic waters.
The Norwegian Polar Institute has a post doc. position (3-year post. doc.) available on Ocean Acidification, with particular focus on acidification processes in ocean waters influenced by sea-ice formation and melting. The post doc. will become part of the staff at the Research Department of the Norwegian Polar Institute, located at the Fram Centre in Troms?, Norway.
Tasks
Dissolved inorganic carbon is released when sea ice is formed, and transported into bottom water masses with dense, brine enriched water. At the same time calcium carbonate is formed, remaining trapped in the ice until it melts. Upon melting, the calcium carbonate dissolution leads to CO2 under saturation, and hence increased oceanic CO2 uptake in the regions of ice melt. The large quantities of sea ice leaving the Arctic Ocean through Fram Strait, subsequently melting in the Nordic Seas, hence represents a sink for atmospheric CO2. As the Arctic is changing, with decreasing sea ice extent and increasing air temperatures, the effect of this sea ice driven carbon pump on the sequestration of CO2 in the Nordic Seas to the deep ocean is also likely to change. The successful candidate will be involved with projects to elucidate these issues in a changing Arctic. In particular how the ice related processes influence the propagation of ocean acidification into the Arctic Ocean. Int
 eraction with ecosystem studies in the same waters to gain an interdisciplinary understanding of the changes is essential for the holder of this position.
We propose to observe and quantify the change in the sea ice driven carbon pump in Fram Strait. In addition to the export of sea ice, the strait is the only passage for Arctic bottom water export. Such research based monitoring would enables us to observe the evolution of both dissolved inorganic carbon in the deep waters and calcium carbonates in the sea ice, at the same site. In addition to quantifying the changes in the sea ice carbon pump, changes in the carbon signal in sea ice and bottom waters would act as tracers for addressing how the ice melt and freeze cycle change internally in the Arctic. A parameter like alkalinity, for example, would add information to tracers like oxygen isotopes and nutrient ratios that are already being sampled on the origins of the water masses exiting Fram Strait. Developing a monitoring system for ocean acidification in polar waters will be a prioritized task.

Qualifications
We are looking for a candidate who holds a Ph.D. degree in a relevant discipline with regard to ocean acidification. The candidate should have oceanography/meteorology and chemistry in the academic background, and should also show capacity for interdisciplinary work. Laboratory and field expertise are desirable, and it would also be an asset if the candidate has modelling and/or statistical skill. The candidate will be expected to interact actively with researchers in ecosystem studies and modelling. The successful candidate will be team-oriented yet expected to conduct independent research, publish in international journals and apply for external funding. The candidate should have an international publication record in a relevant field and network of researchers in ocean acidification.
Salary
The salary will commensurate with the qualifications of the successful candidate, according to the Norwegian State salary code 1352, scale 57 - 68 (NOK 448.400 - 548.200). The work place is the Norwegian Polar Institute, Fram Centre, Troms?, Norway. The position is open, and the successful candidate should be able to start as soon as possible.
General
The Norwegian State Administration strives to mirror the diversity of its population and thereby achieve a balanced mix of age, gender and ethnic backgrounds among its employees. Hence, candidates with immigrant backgrounds and women are encouraged to apply for the position.

The Geography Department at Loughborough University, UK, is offering a fully-funded research studentship in partnership with Extreme World Races (an Antarctic logistics company) for the following project:

Spatio-temporal variation in ice-sheet surface climatology, from interior plateau to ice shelf, in Dronning Maud Land, East Antarctica.
- this project will involve measurement and modelling of the surface energy- and mass-balances along a transect, from the interior ice-sheet to the coastal shelf, over two southern summers and one winter, using Automatic Weather Stations. Of particular interest are the diurnal and seasonal cycling of the boundary-layer meteorology, its relationship with surface mass balance, and how well it is represented by re-analysis data/regional climate model output.

This 3-year studentship pays fees, maintenance at UK/EU rates, and two southern summer seasons of fieldwork through the partnership with Extreme World Races. The start date is 1st October 2011, with travel to Antarctica most likely in December 2011.

Enquiries or expressions of interest should be directed to Richard Hodgkins (r.hodgkins@lboro.ac.uk).
