This project aims to establish continuous Total Gaseous Mercury (TGM) measurements at Amderma, Russia to provide circumpolar data in concert with international sampling efforts at Alert (Nunavut, Canada), Point Barrow (Alaska, USA) and Ny-Ålesund (Svalbard/Spitsbergen, Norway).
The objectives of this project are to determine spatial and temporal trends in atmospheric mercury concentrations and deposition processes of mercury in the Arctic in order to assist in the development of long-term strategies for this priority pollutant by:
A) measuring ambient air TGM concentrations in the Russian Arctic;
B) investigating and establishing the causes of temporal variability (seasonal, annual) in mercury concentrations so that realistic representations (models) of atmospheric pathways and processes can be formulated, tested and validated; and
C) studying the circumpolar behaviour of mercury by comparison with data from other polar sites.
This is a National Implementation Plan (NIP) project

- Stations or areas where observations are made
- Amderma, Russia, starting 2000 - continuous Total Gaseous Mercury (TGM) measurements;
- Cooperation with researchers in other circumpolar countries has also generated TGM
measurements at Alert (Nunavut, Canada), Point Barrow (Alaska, USA) and Ny-Ålesund
- Are data archived or planned to be archived at an AMAP Thematic Data Centre?
If no (or only part of data are reported to a TDC), where and how are (other) data stored?
The data will be provided upon request to the relevant AMAP assessment chapter authors/drafters, assuming a similar data ownership agreement will be adopted for the second AMAP assessment as was used for the first.

Methods & Procedures
- Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.
Surface-level atmospheric TGM samples are collected and analyzed on-site by a Tekran 2537A continuous mercury vapour analyzer (see Schroeder et al. 1997, above).
- QA/QC Information (what QA/QC procedures are implemented, laboratories involvment in QA/QC activities, model verification/validation routines, etc.)
QA/QC procedures follow those of Canada's Northern Contaminants Program and those established for the Canadian Atmospheric Mercury Measurement Network (CAMNet).
- Is this a bi- AND multi-lateral project (i.e. a project involving cooperation between different countries)?
- Other institutes involved in the project
Cooperation among researchers has led to the initiation of similar measurements in Alaska, Svalbard/Spitsbergen (Norwegian Arctic), Greenland, Sweden and Finland.
