AMAP Project Directory
The AMAP Project Directory (AMAP PD) is a catalog of projects and activities that contribute to assessment and monitoring in the Arctic. The Arctic Monitoring and Assessment Programme (AMAP), is a working group under the Arctic Council, tasked with monitoring and asessing pollution, climate change, human health and to provide scientific advice as a basis for policy making.
The directory, which is continously updated, documents national and international projects and programmes that contribute to the overall AMAP programme, and provides information on data access as well as a gateway for the AMAP Thematic Data Centres.
Other catalogs through this service are ENVINET, SAON and SEARCH, or refer to the full list of projects/activities.

- 21. Monitoring the Atlantic Inflow toward the Arctic (MAIA)
-
The overall objective of MAIA is to develop an inexpensive, reliable system based on coastal sea-level data for monitoring the inflows of Atlantic Water to the northern seas. Available observation systems, including stan-dard tidal stations, will be used to obtain transport estimates with a time resolution of less than a week and show that the method is generic and can be applied to a similar monitoring of other regions.
- 22. Ice-sheet mass balance in central West Greenland
-
The aim of the project is to obtain more insight in the response of the Greenland ice sheet to climatic change. For this purpose we will link our surface energy-balance model to an atmospheric model, so that the model can be forced by variables characterizing the atmosphere outside the thermal influence of the ice sheet itself. The modelling is supported by the mass-balance and meteorological data that we collect along a transect in West Greenland (the Kangerlussuaq-transect or K-transect). The albedo of the ice sheet is studied by means of satellite data and measurements obtained from a helicopter. Research activities - develop numerical models of the surface energy balance and the boundary layer above the ice sheet - perform annual measurements of the mass balance and ice velocity along the K-transect - maintain two automatic weather stations along the K-transect - study the surface albedo by means of remote-sensing images - improve methods to retrieve the surface albedo from satellite data by means of measurements obtained from a helicopter
- 23. Polar Exchange at the Sea Surface (POLES)
-
Our broad area of enquiry is the role of polar regions in the global energy and water cycles, and the atmospheric, oceanic and sea ice processes that determine that role. The primary importance of our investigation is to show how these polar processes relate to global climate.
- 24. The Role of Polar Oceans in Contemporary Climate Change
-
Our central geophysical objective is to determine how sea ice and the polar oceans respond to and influence the large-scale circulation of the atmosphere. Our primary technical objective is to determine how best to incorporate satellite measurements in an ice/ocean model.
- 25. Shelf Basin Interactions Program
-
To understand and model the processes by which Arctic deep water is formed on continental shelves by the modification of inflowing Atlantic and Pacific waters.
- 26. Polar Ice Prediction System Version 3.0 (PIPS 3)
-
To develop the next-generation Navy operational ice thickness and movement model.
- 27. Program for Arctic Regional Climate Assessment (PARCA)
-
The Program for Arctic Regional Climate Assessment (PARCA) was formally initiated in 1995 by combining into one coordinated program various investigations associated with efforts, started in 1991, to assess whether airborne laser altimetry could be applied to measure ice-sheet thickness changes. It has the prime goal of measuring and understanding the mass balance of the Greenland ice sheet, with a view to assessing its present and possible future impact on sea level. It includes: · Airborne laser-altimetry surveys along precise repeat tracks across all major ice drainage basins, in order to measure changes in ice-surface elevation. · Ice thickness measurements along the same flight lines. · Shallow ice cores at many locations to infer snow-accumulation rates and their spatial and interannual variability, recent climate history, and atmospheric chemistry. · Estimating snow-accumulation rates from atmospheric model diagnosis of precipitation rates from winds and moisture amounts given by European Centre for Medium-Range Weather Forecasts (ECMWF) operational analyses. · Surface-based measurements of ice motion at 30-km intervals approximately along the 2000-m contour completely around the ice sheet, in order to calculate total ice discharge for comparison with total snow accumulation, and thus to infer the mass balance of most of the ice sheet. · Local measurements of ice thickness changes in shallow drill holes ("dh/dt" sites in Figure 1). · Investigations of individual glaciers and ice streams responsible for much of the outflow from the ice sheet. · Monitoring of surface characteristics of the ice sheet using satellite radar altimetry, Synthetic Aperture Radar (SAR), passive-microwave, scatterometer and visible and infrared data. · Investigations of surface energy balance and factors affecting snow accumulation and surface ablation. · Continuous monitoring of crustal motion using global positioning system (GPS) receivers at coastal sites.
- 28. Fluxes of Mercury from the Arctic Ice Surface during Polar Sunrise Conditions and Melt Conditions
-
The objectives of this project are: A) to determine the pathway for the transfer of mercury in snowmelt to sea water during the melt period at Alert; B) to determine the extent of open water and wet ice in the summer Arctic as it affects the surface exchange of Hg using satellite radar imagery; and C) to determine the atmospheric dynamics associated with the photochemistry of mercury episodically during the polar sunrise period.
