The Geospace environment comprises a complex system of the incoming solar wind plasma flow interacting with the Earth\u0027s magnetic field and transferring its energy and momentum into the magnetosphere. This interaction takes place mainly on the Earth\u0027s dayside, where reconnecting geomagnetic field line might be \"open\" and directly connected to the interplanetary magnetic field lines, thus providing direct pathways for the solar wind energy to be transferred down to the ionosphere and upper atmosphere. The spatial extent of the polar cap areas controlled by the ionospheric plasma convection demarcate the so-called \"Open-Closed Boundary\" where solar wind particles reach down polar ionospheres. Observations of that boundary serve the important role in validating geomagnetic field modeling and help studying space weather. Motivated by the compelling Geospace research in the polar regions, this award will allow scientists to investigate magnetosphere-ionosphere coupling processes and ionospheric irregularities inside the polar caps and their space weather impacts by establishing a new ground-based network that will be deployed in the Antarctic polar cap region. This will be achieved using three new instrumented platforms (next generation of Automatic Geophysical Observatories) along the snow traverse route from the Korean Antarctic Station Jang Bogo toward to the Concordia Station at Dome C by the Korea Polar Research Institute\u0027s (KOPRI) team. Geospace data collected by these three platforms will be shared by the U.S. and Korean researchers, as well as will be made available to other scientists. The research involves early-career researchers, as well as train students who will build and operate remote Antarctic platforms, as well as analyze collected data to investigate space weather events and validate models.

Help on the Results MapX
This window can be dragged by its header, and can be resized from the bottom right corner.
Clicking the Layers button - the blue square in the top left of the Results Map - will display a list of map layers you can add or remove
from the currently displayed map view.
The Results Map and the Results Table
- The Results Map displays the centroids of the geographic bounds of all the results returned by the search.
- Results that are displayed in the current map view will be highlighted in blue and brought to the top of the Results Table.
- As the map is panned or zoomed, the highlighted rows in the table will update.
- If you click on a centroid on the map, it will turn yellow and display a popup with details for that project/dataset - including a link to the landing page. The bounds for the project(s)/dataset(s) selected will be displayed in red. The selected result(s) will be highlighted in red and brought to the top of the table.
- The default table sorting order is: Selected, Visible, Date (descending), but this can be changed by clicking on column headers in the table.
- Selecting Show on Map for an individual row will both display the geographic bounds for that result on a mini map, and also display the bounds and highlight the centroid on the Results Map.
- Clicking the 'Show boundaries' checkbox at the top of the Results Map will display all the bounds for the filtered results.
Defining a search area on the Results Map
- If you click on the Rectangle or Polygon icons in the top right of the Results Map, you can define a search area which will be added to any other search criteria already selected.
- After you have drawn a polygon, you can edit it using the Edit Geometry dropdown in the search form at the top.
- Clicking Clear in the map will clear any drawn polygon.
- Clicking Search in the map, or Search on the form will have the same effect.
- The returned results will be any projects/datasets with bounds that intersect the polygon.
- Use the Exclude project/datasets checkbox to exclude any projects/datasets that cover the whole Antarctic region.
