However, we know very little about the microscopic organisms living in the soil in this region. Soil biology (including bacteria, fungi, and invertebrates) are responsible for many important processes that sustain ecosystems, such as nutrient recycling. Without understanding the environmental conditions that influence soil biodiversity along the Antarctic Peninsula, our ability to predict the consequences of global change is strongly limited. This project will identify the soil community at many sites along the Antarctic Peninsula to discover how the community changes with environmental conditions from north to south. The project will also identify how the soil community at each site differs under different types of plants. Understanding more about the ways in which plant cover and climate conditions influence soil biodiversity will allow predictions of how communities will respond to future changes such as climate warming and invasive plant species.

Using the most modern biological (genomic), geochemical techniques, and advanced chemical instrumentation researchers will 1) optimize protocols for collecting, extracting and amplifying DNA from deep ice cores suitable for use in next generation pyrosequencing; 2) determine the microbial diversity within the ice core; and 3) obtain and analyze detailed molecular characterizations of the carbon in the ice by ultrahigh resolution Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR-MS). With this pilot study investigators will be able to quantify the amount of material (microbial biomass and carbon) required to perform these characterizations, which is needed to inform future ice coring projects. The ultimate goal will be to develop protocols that maximize the yield, while minimizing the amount of ice required.

This window can be dragged by its header, and can be resized from the bottom right corner.

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.

Viewing map layers on the Results Map

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.
