Directory entires that have specified Dirigibile Italia, Ny-Ålesund as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

The project, Arctic and Alpine Stream Ecosystem Research (AASER), started within EU’s Climate & Environment Programme and now continues with national funding, primarily Norway, Italy and Austria. The objective is to study dynamics and processes in rivers systems in Arctic and Alpine regions. Emphasis is given to the relationships between benthic invertebrates and environmental variables, especially in glacier-fed systems and in relation to climate change scenarios. On Svalbard research is concentrated around Ny Ålesund, particularly Bayelva and Londonelva. In 2004 the focus will be on the use to stable isotopes to detect transfer processes within and between ecosystems.
Italy’s leading national research institution, the CNR has been supporting research activity at Ny-Ålesund since 1997, when the scientific station “Dirigibile Italia” was acquired. This infrastructure supports Arctic research conducted by the national research community. In 2008, it was improved through the construction of the Amundsen-Nobile Climate Change Tower and the actikvity largely enlarged with the Climate Change Tower Integrated Project (CCT-IP - www.isac.cnr.it/~radiclim/CCTower). Scientific cooperation, particularly focused on atmospheric science including pollutants distribution and ozone studies, on oceanography and on marine biology and biodiversity was developed by CNR scientists in particular with NPI and AWI; CNR is coordinating actions (EU-GMOS project) to improve and implement the observational system related to mercury. CNR is also involved in the SIOS preparatory phase project, and in Italy it is engaged to coordinate interested Italian expertises in a common scientific plan and actively promote Italian participation to SIOS final multidisciplinary platform. In the years to come, CNR intends to promote the improvement of research activity and to reinforce international cooperation of the Italian research groups, and to provide a significant contribution to the observational system in the Arctic, following the lines recommended by SAON. Together with the improvement/development of a supersite at Ny-Ålesund and large contribution to SIOS, CNR will operate to contribute/sustain thematic networks (Polar-AOD for aerosol and GMOS for mercury leading from CNR).
The 2003 field activity will be mainly dedicated to coring activity which includes: 1. the sampling of snow and ice cores from a Ny-Ålesund nearby glacier (midre Lovenbreen). 2. the collection of near coast (Kongsfjorden) and lakes sediments (maximum under pack depth 30 m). Sampling collection of ice and sediment cores will be performed using a portable, electric operated, sampling corer. The transport of all materials up to each sampling station should be performed with snowcats.
One of the major benefits of performing measurements at Ny-Ålesund is the availability of a monitoring station on Mount Zeppelin, 474m asl. Given the typical height of the Arctic inversion layer during the envisaged measurement period, it will be possible to continuously monitor mercury and particulate in the free troposphere at the same time as performing ground level monitoring. The simultaneous measurements above and below the boundary layer should provide evidence for the mode of elemental Hg replenishment, whether it is from due to exchange with the free troposphere, or transport occurring at sea level. The proposed collaboration, by collecting data from two strategically placed Arctic stations, in the paths of different air masses and data from above the Arctic inversion layer would provide the most comprehensive set of Arctic mercury measurements performed to date.
The structure and role of the cyanobacterial communities that colonise bare soils and fix nitrogen in the arctic ecosystem will be studied. The planned activities will focus on the isolation, identification and characterisation of cyanobacteria from arctic habitats and on the changes of the cyanobacterial community along a transect from a retreating glacier front to a more stable habitat characterised by the presence of mature vegetation. For these purposes, a polyphasic approach encompassing microbiological, morphological and molecular techniques will be applied to environmental samples and isolated cultures. The obtained results will give new insights on the diversity and role of nitrogen fixing cyanobacteria in the arctic and, in more general terms, on ecosystem development under changing climatic conditions.
