The aim of the present project is to continue the monitoring of contaminants in the atmosphere in Greenland to detect temporal and geographical changes and to understand the mechanisms behind them especially those related to climate and to changes in sources and source regions.
Marin Basis Monitoring Program is a part of the GEM program, and take place in Young Sund every year in late July until middle of August. The program follows the levels and changes in
The objective of the project is to strengthen the understanding of the regional and local processes controlling the arctic climate changes. It is our intension to observe the development of CO2 in the arctic atmosphere at Zackenberg Marine Station by an artic fjord sampling and analyzing concentrations as well as the fluxes. We will carry out intensive measurements of CO2 fluxes and carbonate chemistry in the ice and water during the time of ice break up and measurements of CO2 fluxes during the full year.
This project focusses on the monitoring of climate-relevant parameters as in this case the scattering potential of the ambient aerosol population at Villum Research Station (VRS), Station Nord (SN), North Greenland and the determination of the energy budget including ingoing and outgoing short-wave and long-wave radiation. The data will be of high relevance to better quantity the contribution of the direct aerosol effect in the high Arctic.
Sailing expedition from St. John’s to southern Greenland and up the west coast to Upernavik (farther north, if time and conditions allow). CTD profiles in fjords to compliment additional cruises in our effort to understand ice sheet-ocean interactions. GPS trackers and a small drone will be used to study iceberg trajectories and iceberg-ocean interactions.

Northeast Greenland is a key region for studying past sea ice variability and glacier melt-off and their impact on the environment and biota. Very little research has yet been carried out on the marine realm off NE Greenland, and thus there is a limited understanding of modern and past climate and environment along the NE Greenland shelf and coast. The NorthGreen2017 expedition will focus on the past and current changes in Arctic ice shelves, ocean circulation, sea ice extent, sediment transport and freshwater discharge from the Greenland ice cap.
The major objective of this project is to recover (i) the ice-tethered mooring equipped with current velocity and CTD profilers, (ii) Ice Mass Balance Buoy, and (iii) a time-lapse camera, all deployed in April 2016. The recoveries will be accompanied with the collecting of CTD data along the glacier terminus and within the glacier mélange. The current measurements along with the timeseries of vertical CTD profiles will provide a new piece of information about the release of freshwater from beneath the glacier over the course of the year.
This project involves the growing of young sea ice in a specifically designed tank within a so-called oil curtain that limits the oil to a pre-defined space. 20 liters of light crude oil will be introduced from beneath the sea ice into the system when ice has grown to a certain thickness (about 6 cm). The radar signature of the system will be measured continuously through a C-band scatterometer to measure the changes due to the oil injection, and also as oil moves through the system.
