In 2013 a new ecosystem monitoring programme “DiskoBasis” was initiated at Arctic Station on Disko Island, Greenland. The project is partly funded by the Danish Energy Agency. The primary objective of DiskoBasis is to establish baseline knowledge on the dynamics of fundamental physical parameters within the environment/ecosystem around Arctic Station. This initiative extends and complements the existing monitoring carried out at Arctic Station by including several new activities –especially within the terrestrial and hydrological/fluvial field. DiskoBasis include collection of data in the following sub-topics; • Gas flux, meteorology and energy balance • Snow, ice and permafrost • Soil and soil water chemistry • Vegetation phenology • Hydrology -River water discharge and chemistry • Limnology -Lake water chemistry • Marine -Sea water chemistry
The main objective is to quantify the annual mass loss of the Greenland ice sheet, track changes in the extent of local glaciers and ice caps, and track changes in the position of the ice-sheet margin. Network type: - Observing and modelling the ice-sheet surface-mass balance - Quantifying the mass loss caused by iceberg calving - Monitoring the change of glaciers and ice caps in Greenland - Outlook
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.
Multidisciplinary investigations at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN are carried out at a total of 21 permanent sampling sites in water depths ranging between 250 and 5,500 m. From the outset, repeated sampling in the water column and at the deep seafloor during regular expeditions in summer months was complemented by continuous year-round sampling and sensing using autonomous instruments in anchored devices (i.e., moorings and free-falling systems). The central HAUSGARTEN station at 2,500 m water depth in the eastern Fram Strait serves as an experimental area for unique biological in situ experiments at the seafloor, simulating various scenarios in changing environmental settings. Time-series studies at the HAUSGARTEN observatory, covering almost all compartments of the marine ecosystem, provide insights into processes and dynamics within an arctic marine ecosystem and act as a baseline for further investigations of ongoing changes in the Fram Strait. Long-term observations at HAUSGARTEN will significantly contribute to the global community’s efforts to understand variations in ecosystem structure and functioning on seasonal to decadal time-scales in an overall warming Arctic and will allow for improved future predictions under different climate scenarios.
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.
Runoff, precipitation, snow water equivalent and frost depth are measured from catchment areas of 0.07-122 km² in area. Water quality, suspended solids and nutrient load is also monitored in part of the areas. The aim is to produce long-term data series for research with special focus on the effects of land on runoff and water quality. Project is managed by Finnish Environmental Institute (SYKE).
Project intends to produce remote sensing information of sea ice and snow cover in Northern Europe. It is joined international project between ESA, GMES, Polarview and Finnish Environmental Institute. FEM uses the satellite images to follow the snow and ice melt in spring months (march-June) in Finland.
Hydrological monitoring aims produce real time information of water level and discharge, ice thickness including freeze-up and break-up in winter from a network of monitoring stations. Monitoring data is utilized in water resource planning, water management and flood damage prevention. Monitoring is coordinated by Finnish Environmental Institute (SYKE).
The objective of the project was the investigation of englacial melt water channels of Svalbard glaciers in order to find in situ organic material within glacier caves. Specified organic material found beneath glaciers was meant for radiocarbon dating and creation of reliable geochronologies of glacier recessions with considerable smaller glacier termini than present on Svalbard. First radiocarbon dating results ever from organic material found under a glacier’s bottom of glacier Longyearbreen will be published this year. The different moss species ranging from Tomentypnum nitens, Sanionia uncinata, Distichium spp., Syntrichia ruralis gave ages between 1900 and 1100 cal yr BP (Humlum et al., 2004).
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.
The central objectives of the proposed ATMAS project are: to quantify the photo-chemically triggered NOx and HONO re-emission fluxes from permanently and seasonally snow-covered surfaces in the Arctic near Ny-Ålesund, to quantify the sources of NO3 in these snow-covered surfaces. In detail, the following scientific objectives of ATMAS can be distinguished: 1. to quantify atmospheric gradient fluxes of HNO3, HONO, particulate nitrogen compounds, and nitrogen in precipitation (snow and rain) above snow surfaces; 2. to quantify the emission of NOx and HONO from the snow pack as atmospheric gradient fluxes 3. to formulate an influx-outflow relationship that can be used in dependence on the snow type for (photo-)chemical atmospheric process models. The results of this research may be expanded to a regional (European) or global scale, to suggest how the NOx and HONO re-emission process and its consequences can be included into regional emission, dispersion and deposition models used in Europe.
The aim of this project is to study the physical oceanography of the sea in the area where Kongsbreen glacier get in touch with the sea in the inner part of Kongsfjord. In particular the project aims: to characterise temperature and salinity of water masses in the inner part of Kongsfjord close to Kongsbreen Glacier to characterise major fresh water outflow from Kongsbreen glaciers to the sea in the inner part of the fiord to collect time series if seawater currents in-out from the inner part, temperature and salinity patterns for one year from summer 2001 to summer 2002. to collect a one year time series of sea level changes by an automatic self recording depth gauges deployed close to the base.
The general objective of this research concerns the quantitative and qualitative study of particulate matter retained in natural (sea-ice and sediment) and artificial (sediment traps) traps in order to determine the main origin (autochtonous and allochtonous) and the relative importance of different fractions of particulate matter and to follow their fate in the environment. To quantify the autochtonous origin of particulate matter, primary production, nutrient uptake, biomass distribution, phytoplankton community structure and fluxes in the first levels of the trophic chain will be investigated. Studies will be conducted in the sea-ice environment and in the water column and compared to the particle fluxes measured both in the water, using sediment traps and in the sediment, by radiometric chronology, in order to estimate the different contribution of these habitats to carbon export to the bottom. The zooplankton will be identified and counted and primary production, nutrient uptake and phytoplankton dynamics will be related to hydrological structure and nutrient availability in the environment. The Kongsfjord results particularly suitable for the main objective of this research as it is influenced by important inputs of both atmospheric (eolic and meteroric) and glacial origin and is characterised by a complex hydrological situation which may promote autochtonous productive processes, thus determining important particulate fluxes.
The main goal of this research project is to complete the collection of snow/ice field data and to improve the organization of snow/ice spectral signatures, and structural data, along with ancillary information in the existing archive.
IRIS brings together several EU partners to investigate methods to estimate sea ice ridging severity from satellite imagery and assess the impact of these ridges on icebreaker transit times, particularly in the Baltic Sea. The consortium is largely Finnish and is co-ordinated by the Helsinki Technical University. SAMS’ role is to study statistical properties of synthetic aperture radar (SAR) images and relate these to ridge parameters.
-Quantify changes in ice dynamics and characteristics resulting from the switch in AO phase -Establish a climate record for the region north of Greenland through the retrieval and analysis of sediment cores -Improve an existing dynamic-thermodynamic sea ice model, focusing on the heavily deformed ice common in the region -Relate the region-specific changes which have occurred to the larger-scale Arctic variablity pattern -Place the recent ice and climate variability for this critical region into the context of long term climate record, as reconstructed from sediment cores
SITHOS (Sea Ice Thickness Observation System) is also a three-year EU Framework 5 project. The Nansen Environmental Remote Sensing Centre (NERSC) will co-ordinate six institutions in the development of an integrated system for measuring sea ice thickness in the Arctic Ocean. Several approaches for obtaining ice thickness will be used, including novel flexural-wave methods, remote sensing and electromagnetic induction techniques. SAMS’ role is to provide data from UK submarines and aid in the development of the novel tiltmeter-based instruments. Data will be used to improve sea ice models and validate the new CRYOSAT satellite sensors. The resulting synoptic thickness monitoring network will be used to investigate the postulated dramatic thinning in the Arctic Ocean sea ice cover as a result of climate change.
Study of the energy exchange between atmosphere, sea ice and ocean during freezing and melting conditions; within that, measurements of solar radiation (visible and UV) and optical properties, snow and sea ice characteristics, vertical heat and salt fluxes, oceanographic parameters.
During the spring/summer transition, sea ice and snow properties change considerably in response to warming and the eventual reversal of temperature gradients within the snow and ice. Snow melt water percolates down towards the colder snow/ice interface, where it refreezes to form superimposed ice. On sea ice this process occurs probably longer and more intensive than on land, because throughout the summer the ice and underlying seawater is always colder than the snow. In Antarctica superimposed ice may actually form layers of some decimeters in thickness. The objective of this study is to investigate the main processes and boundary conditions for superimposed ice formation, in recognition of its importance for Antarctic sea ice, and its possible importance for Arctic sea ice in case of environmental changes due to future climate change. This will be performed by means of modeling as well as by combined measurements of the temporal evolution of snow and ice properties and the energy budget.
