Greenland: projects/activities

The objective of the station is to facilitate ecosystem research in the High Arctic. According to the framework programme of Zackenberg Ecological Research Operations (ZERO) this includes: - Basic quantitative documentation of ecosystem structure and processes; - Baseline studies of intrinsic short-term and long-term variations in ecosystem functions; - Retrospective analyses of organic and inorganic material to detect past ecosystem changes; - Experimental studies enabling predictions of ecosystem responses to Global Change. The programme is coordinated with Nuuk Ecological Research Operations (see below) within the Framework of Greenland Ecosystem Monitoring (GEM). Main gaps: Winter dynamics

The objective is to allow comparative studies of ecosystem dynamics in relation to climate variability and change in respectively a high arctic and low arctic setting as Nuuk Basic comprises the same components as Zackenberg. According to the framework programme of Zackenberg Ecological Research Operations (ZERO) this includes: - Basic quantitative documentation of ecosystem structure and processes; - Baseline studies of intrinsic short-term and long-term variations in ecosystem functions; - Retrospective analyses of organic and inorganic material to detect past ecosystem changes; - Experimental studies enabling predictions of ecosystem responses to Global Change. The programme is coordinated with Zackenberg Ecological Research Operations (see above) within the Framework of Greenland Ecosystem Monitoring (GEM). Main gaps: Winter dynamics

The purpose of the BioBasis programme is to monitor basic qualitative and quantitative elements of biodiversity in the terrestrial ecosystems at Zackenberg in Northeast Greenland. The programme provides data on typical High Arctic species and processes that can be expected to react on year to year variation in climate as well as long-term climate change. It includes 30 variables of terrestrial and limnic plant, arthropod, bird and mammal dynamics in the Zackenberg valley.

Monitoring climatological and hydrological parameters in a low arctic environment.

Important progress has been made in recent decades to describe and understand how arctic terrestrial vertebrate interact, especially concerning predator-prey interactions. Indirect interactions between different prey species modulated by shared predators (e.g. Arctic fox) are believed to have important impacts on the structure and/or dynamics of some communities. Yet, our understanding of these types of interactions is still fragmentary. To fill that gap, we will build on ongoing projects exploring related questions in Canada (Marie-Andrée Giroux, Nicolas Lecomte, Joël Bêty) and Greenland (Olivier Gilg, Niels M. Schmidt), while taking advantage of existing networks (ADSN in North America and “Interactions” program in Greenland and Eurasia). The aim of the project is to promote the implementation of several common protocols that will (1) improve each collaborator’s knowledge at the site level and, more importantly, that will (2) be merged across sites and years to improve our understanding of the functioning and the influence of indirect interactions on arctic vertebrate communities in general.

Five types of data have been identified (by the 5 initiators of the project already mentioned above) as being mandatories to answer questions related to this topic. These data sets will be collected using 5 specific protocols described in the following chapters:

1. Monitor predation pressure using artificial nests
2. Monitor real predation pressure on Calidris nests using Tiny Tags
3. Observations of predators and lemmings (3b: fox scats DNA barcoding)
4. Assessing lemming (or “rodent”) relative abundance using different methods
5. Assessing “herbivores” (excl. rodents) relative abundance using “faeces transects”

The GeoBasis programme collects data describing the physical and geomorphological environment in Zackenberg, North East Greenland. This includes CO2-flux, snowcover and permafrost, soil moisture, –chemistry and nutrient balance, hydrology, river discharge and –sediment. GeoBasis also supports the ClimateBasis programme with service and datahandling during the field season.

Our objective in present SAON meeting was to know more about SAON activities and plannings to coordinate and promote guidelines criteria for observations in the ARctic Present Spain Research in Arctic is performed mainly for universities and scientific institutions , down the responsability of the Science Department with the support of several national institutions including the Defense Department and Foreign Affairs Institutions are coordinated by the National Polar Committee. The National Scientific Program finance the activities in the polar zones Although our main scientific activities are in Antarctica the activity of Spain in Arctic is rapidly increasing following the fact that Arctic research is a priority task in our Science Program At present we have detected 16 scientific groups working activelly in the differnts fields of Arctic topics (glaciology, meteorology, permafrost, high atmosphere, ecology, physical oceanography, marine geology and biology) These activities are mainly performed in cooperation with Arctic countries Institutions via institutional or researchers contacts About our media to work in Arctic ocean Spain has at present two multiporposes oceanographic research ships In the last years our Ocanographic ship Hesperides has developed two campaigns in The area of Greenland and Svalvars Island in the fields of marine Geology , marine biology and physical oceanography For next summer Hesperides will perform a third oceanographic campaign close to the Atlantic coast of Greenland Other national institutions have been working in marine biology campaigns including fisheries stock evolution Spain has a National Centre of Polar Data were all researchers must enter their raw data gathered in the polar campaigns We considerer , at present , our interest to cooperate inside SAON board, considering that besides other possible cooperation to SAON tasks could be a cooperation with our Polar Data Centre

NASA satellites (Figure 13) support an extensive Global Water Cycle science focus area and contribute to high accuracy, stable, sustained observations and associated modeling for terrestrial hydrology and cryosphere studies. Derived geophysical products for terrestrial hydrology and cryosphere are available from the NSIDC’s Distributed Active Archive Center (DAAC). They include: soil moisture and snow water equivalent from AMSR-E; Greenland ice sheet altimetry and global land surface altimetry from ICESat/GLAS; snow cover extent/area from MODIS; surface albedo and temperature from AVHRR Pathfinder. SAR data obtained from a variety of foreign satellites since 1991 are archived at the ASF DAAC. SAR data provide opportunities for change detection, including interferometric SAR (InSAR) studies of glacier and ice sheet surface elevation and dynamics (ice velocity maps), land surface elevation, and soil moisture. GRACE has been used to determine the mass loss from the Greenland ice sheet and from glaciers in southeast Alaska. The surface elevation of the Greenland ice sheet is mapped using ICESat, and the Advanced Spaceborne Thermal Emission and Reflec¬tion Radiometer (ASTER) is used to acquire imagery and topography of the ice sheet.

The purpose of the project is to combine the Danish Meteorological Institute’ HIRHAM climate model and permafrost research. This collaboration between the two fields is expected to result in a prognosis of changes in the permafrost distribution in Western Greenland (maritime Arctic climate) and Alaska (continental Arctic climate) to the year 2050. Network type: permafrost

The main objective is to provide management advice for harvested species (large whales, narwhale and beluga, walrus). The surveys are conducted from fixed winged twin engine aircrafts with 2-4 observers, that systematically survey for marine mammals in the prime habitats in Greenland. Surveys are conducted as strip census, line transect, photographic survey or independent observer surveys. Target species and areas shift between years but it is attempted to maintain a 5-6 survey cycle in the areas with the largest hunting pressure (i.e. West Greenland). For East Greenland a survey cycle of 10 or more years will be maintained.

The Nuuk-Basic project aims to establish a climate monitoring programme on the westcoast of Greenland. During two workshops, one being in Nuuk with field survey, framework for a future climate monitoring programme will be established. The programme builds on the concept and institutions already performing climate monitoring in NE-Greenland through ZERO (Zackenberg Ecological Research Operations).

The ZERO database contains all validated data from the Zackenberg Ecological Research Operations Basic Programmes (ClimateBasis, GeoBasis, BioBasis and MarinBasis). The purpose of the project is to run and update the database with new validated data after each succesfull field season. Data will be available for the public through the Zackenberg homepage linking to the NERI database. The yearly update is dependent on that each Basis programme delivers validated data in the proscribed format.
