The 2009–2010 Arctic polar stratospheric cloud season: a CALIPSO perspective
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 5. Pitts M.C.; Poole L.R.; Dörnbrack A.; et al. - Copernicus GmbH, 2011Spaceborne lidar measurements from CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) are used to provide a vortex-wide perspective of the 2009–2010 Arctic PSC (polar stratospheric cloud) season to complement more focused measurements from the European Union RECONCILE (reconciliation of essential process parameters for an enhanced predictability of Arctic stratospheric ozone loss and its climate interactions) field campaign. The 2009–2010 Arctic winter was unusually cold at stratospheric levels from mid-December 2009 until the end of January 2010, and was one of only ...

Characteristics, sources, and transport of aerosols measured in spring 2008 during the aerosol, radiation, and cloud processes affecting Arctic Climate (ARCPAC) Project
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Brock C.A.; Cozic J.; Bahreini R.; et al. - Copernicus GmbH, 2011We present an overview of the background, scientific goals, and execution of the Aerosol, Radiation, and Cloud Processes affecting Arctic Climate (ARCPAC) project of April 2008. We then summarize airborne measurements, made in the troposphere of the Alaskan Arctic, of aerosol particle size distributions, composition, and optical properties and discuss the sources and transport of the aerosols. The aerosol data were grouped into four categories based on gas-phase composition. First, the background troposphere contained a relatively diffuse, sulfate-rich aerosol extending from the top of the sea ...
International Polar Year (IPY). Understanding Earth's Polar challenges : International Polar Year 2007-2008 - summary by the IPY Joint Committee
The International Polar Year (IPY) 2007–2008, co-sponsored by ICSU and WMO, became the largest coordinated research program in the Earth’s polar regions, following in the footsteps of its predecessor, the first and second International Polar Years in 1881-1883 and 1932-1933 and the International Geophysical Year 1957–1958.
An estimated 50,000 researchers, local observers, educators, students, and support personnel from more than 60 nations were involved in the 228 international IPY projects (170 in science, 1 in data management, and 57 in education and outreach) and related national eff ...
Sea Ice and Products and Services of the National Ice Center
This two-hour module examines sea ice, icebergs, and the products and services of the National Ice Center and the North American Ice Service. Topics include climatology and current trends in sea ice extent and thickness; the development, classification, and drift of sea ice and icebergs; fractures, leads and polynyas; and the satellite detection of sea ice using visible, infrared, and microwave sensors.

Growth pattern of a common feather moss, Hylocomium splendens, from contrasting water regimes in a high Arctic tundra
Antarctic Record, Vol. 54, No. 2. Ueno Takeshi; Kanda Hiroshi - Scholarly and Academic Information Navigator (CiNii), 2010Hylocomium splendens, a widespread feather moss, is one of the major plant species found in high-Arctic tundra. It occupies a variety of habitats ranging from exposed dry ground to swampy areas. To clarify the effect of the water regime on the growth pattern of H. splendens, the shoot morphology of H. splendens growing in contrasting water regimes, i.e. hydric, mesic and xeric sites, was investigated using retrospective analyses of growth. The derived growth parameters for H. splendens differed considerably among the sites. The growing period at the hydric, mesic and xeric sites was 1 year, 2 ...

An Arctic Sea Ice Simulation Using an Ocean-Ice Coupled Model
Atmospheric and Oceanic Science Letters, Volume 3 Number 4. Sun Hong-Chuan; Zhou Guang-Qing - Science Press, 2010This paper evaluates the simulation of Arctic sea ice states using an ocean-ice coupled model that employs LASG/IAP (the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics/ the Institute of Atmospheric Physics) Climate Ocean Model (LICOM) and the sea-ice model from the Bergen Climate Model (BCM). It is shown that the coupled model can reasonably reproduce the major characteristics of the mean state, annual cycle, and inter-annual variability of the Arctic sea ice concentration. The coupled model also shows biases that were generally pre-sented in ...

Arctic Biodiversity Trends 2010
GRID Arendal, 2010A component of the comprehensive Arctic Biodiversity Assessment (ABA) of the Arctic Council, this report provides a snapshot of the trends being observed in Arctic biodiversity today. Twenty-two indicators examine the current state of the environment. Issues include sea birds, fisheries, climate change, polar bears and traditional knowledge.

IUCN/NRDC Workshop to Identify Areas of Ecological and Biological Significance or Vulnerability in the Arctic Marine Environment : Workshop Report
Human activity is expanding in the Arctic marine environment, in part due to warming ocean temperatures and the dramatic loss of summer sea ice. New and expanding human uses include fishing, shipping and offshore oil and gas development. All have the potential to place major additional stress on ocean ecosystems which are already undergoing profound change related to warming, sea ice loss, and alterations in ocean chemistry.
Because activities conducted in one nation's waters can affect other parts of the region, effective management of some human uses in the Arctic marine environmen ...
Why monitor the Arctic Ocean? Services to society from a sustained ocean observing system
Bates Peter; Alverson Keith; Intergovernmental Oceanographic Commission (IOC); et al. - UNESCO, 2010Never has accurate information been more important, yet at
present we know very little about the Arctic Ocean. Critical physical processes are poorly understood, ecosystems remain unstudied and undiscovered, and indigenous voices go unheard. This lack of knowledge thwarts efforts to detect, predict or manage the interrelated physical, biological and social impacts of climate change, making sustainable development almost impossible. A coordinated observing system must therefore be
created for the Arctic Ocean and its coasts, to provide baseline data and ensure sustained monitor ...
