  1. Alfred Wegener Institute seeks Two Scientists
    Sea Ice Physics
    Bremerhaven, Germany

The Alfred Wegener Institute for Polar and Marine Research seeks
applicants for two positions for scientists in the Sea Ice Physics
section of the Climate Sciences Division.

For the first position (index code 83/D/KL) , applicants should
contribute to the forecasting of sea ice properties of the Arctic Ocean
in order to advance ice-routing advice for shipping in ice covered seas.
Necessary activities encompass implementation and assessment of
additional physical processes within the existing ocean-sea ice model
NAOSIM as well as the execution of high-resolution simulations with
numerical models of the Arctic Ocean. Furthermore, an important task is
the exchange of results with other groups participating in the project.
Applicants must have a Master's and a PhD in geophysics, physics,
meteorology, oceanography, or a related discipline. Substantial
knowledge of computer programs (e.g., UNIX, Fortran, script languages,
visualization tools) and interest in the role of sea ice within the
climate system is expected, as is the willingness to participate in
expeditions to the polar region. Experience in large-scale ocean
modeling or adjoint methods of data assimilation are beneficial.

The second position (index code 84/D/KL) focuses on design, realization,
and analysis of calculations with coupled global climate models for
decadal climate prediction. Novel efforts for the initialization of the
climate system shall be developed and tested for predictions over
periods of several years up to decades. Applicants must have a Master's
and a PhD in geophysics, physics, meteorology, oceanography, or a
related discipline. Solid knowledge of numerical simulation of complex
hydro-dynamic processes and of climate physics is expected, as is
willingness to participate in expeditions to the polar region.
Experience with coupled climate models or prediction of climate
phenomena would be an advantage.

Both positions are limited to three years. Applications, including the
usual documents with reference to the index number should be sent by
Thursday, 15 December 2011 to:

Alfred Wegener Institute for Polar and Marine Research
Personnel Department
PO Box 12 01 61
27515 Bremerhaven
Germany

  1. Naval Research Laboratory seeks Postdoctoral Candidate
    Oceanography Division
    Stennis Space Center, Mississippi

The Ocean Dynamics and Prediction Branch of the Naval Research
Laboratory (NRL) seeks a postdoctoral research associate able to improve
and apply large, complex numerical modeling codes for ocean circulation,
sea ice, and/or ocean surface waves. The position is open to U.S.
citizens and permanent residents only.

The selected applicant will work with other NRL scientists on a new
project to study the impact of reduced ice volume in the arctic
ice-ocean system using satellite, airborne, and in situ observations
with coupled ice-ocean-wave models. Broad tasks may include:

- Quantifying the effect of increasing open water (e.g., increased
absorption of solar radiation and fresher surface water) on
two-layer arctic ocean circulation (e.g., mixing);
- Developing a new wave model source term for attenuation and
scattering of wave energy by ice floes;
- Explaining and quantifying the role of surface waves and ocean
currents in determining the type of ice cover, floe size
distribution, and the nonstationary transition from MIZ to
continuous ice;
- Developing strategy for assimilation of snow and ice thickness
data in the ice model; and
- Quantifying the impact of more accurate remotely sensed snow and
ice thickness data on predictions.

Strong programming skills, especially with Fortran, are required.
Familiarity with the CICE, HYCOM, and/or WAVEWATCH III models would be
beneficial. Candidates must have a PhD or equivalent in a relevant field
within the last three years.

To apply, send application letter and curriculum vitae to:

  1. University of Alaska Anchorage seeks Postdoctoral Fellow
    Ecohydrologist/Ecosystem Ecologist
    Anchorage, Alaska

The Environment and Natural Resources Institute (ENRI) at the University
of Alaska Anchorage (UAA) is seeking an Ecohydrologist/Ecosystem
Ecologist for a two-year postdoctoral fellow position with field studies
at Toolik Lake, Alaska.

The research is an Office of Polar Programs Arctic Observing Network
EAGER project pending anticipated funding. The study will quantify
ecosystem and landscape-scale ecohydrology with a focus on using water
vapor isotopes as tools to understand biosphere-atmosphere interactions
and as a basis to estimate the magnitudes and patterns of evaporation
and transpiration. The project will focus on measuring and monitoring
ecosystem water vapor isotope characteristics using a Picarro water
vapor isotope unit on a micrometerological tower in concert with
periodic aircraft campaigns that will simultaneously be measuring water
vapor isotope traits at the landscape-scale. The incumbent will operate
and maintain a Picarro 2120i water vapor isotope unit from mid-May to
mid-September 2012 at Toolik Lake, and will be responsible for the daily
operation and comparing and contrasting the isotopic values (and
estimated fluxes) to those periodically measured by a research aircraft
with over flights in June, July, and August. The individual will be
stationed at the Toolik Lake Field Station during the summer and at UAA
in winter.

A PhD or previous postdoctoral research experience in hydrology,
micrometerology, ecosystem ecology, biogeochemistry, or physiological
plant ecology is preferred, as is prior use of Picarro liquid or water
vapor isotope units. The appointment is expected to begin March 2012.
Screening of applicants will begin 10 December 2011 and continue until
filled.

  1. Deadline Extended: Environment Canada seeks Postdoctoral Fellow
    Environmental Chemistry or Environmental/Chemical Engineering
    Toronto, Ontario, Canada

Environment Canada seeks a postdoctoral fellow in environmental
chemistry or environmental/chemical engineering. The position will be
based in Toronto, Ontario, Canada.

The successful candidate will work on Northern Contaminants Program
(NCP) project entitled "Northern Contaminants Air Monitoring: Organic
Pollutant Measurements." The position is available from March 2012 to
March 2013, and renewable for up to 3 years until March 2015 depending
on funding availability and performance.

Atmospheric measurements of persistent organic pollutants (POPs) and
emerging chemicals have been conducted in the Canadian Arctic since
1992. From these measured results, the candidate will deduce where these
chemicals have come from, how much from which region, what climate
conditions influence their movement to the Arctic, and whether the
concentrations are changing in response to domestic and international
control strategies. Air samples will be screened for new chemicals of
concern to assess their potential of arctic contamination. Data
collected will be incorporated into environmental transport models to
determine how future climate change will affect contaminant transport to
the Arctic.

Applicants must have graduated or completed all requirements to graduate
before March 2011 from a recognized university with a PhD specializing
in environmental chemistry or environmental/chemical engineering. A
background in meteorology pertaining to atmospheric pollutant transport
is considered an asset. The successful candidate should be an expert in
environmental organic chemistry and atmospheric contaminant transport,
and should possess the following qualities:

- Extensive experience in field measurements of trace levels of
atmospheric pollutants, including POPs and/or other priority organic
contaminants;
- Extensive experience in laboratory analysis and quality
assurance/quality control (QA/QC) of trace organic pollutants in
environmental samples;
- Comprehensive knowledge in the principles of atmospheric transport
mechanisms, chemical properties, and environmental behavior of POPs;
- Ability to analyze atmospheric measurement data using statistical
techniques for source identification, apportionment, and chemical
profile fingerprinting; and
- Ability to communicate effectively in English, both orally and in
writing.

Applicants should send a 500-word summary of your PhD thesis and
previous work experience, highlighting experience relevant to the
abovementioned research; a curriculum vitae, and a copy of their
transcript via email to Hayley Hung (hayley.hung [at] ec.gc.ca).

Extended application deadline: Monday, 12 December 2011.
