Welcome


How to use this data portal

The Chicken Creek data portal offers an interface for displaying and downloading data and aerial photos of the catchment.

In order to download data and aerial photos you have to be logged in with a password provided by the Research Center Landscape Development and Mining Landscapes. Write an informal request to fzlb@b-tu.de to obtain a password. Please describe your research field and how you intend to use the data.

Please cite "BTU - FZLB" as a source if you use data or aerial photos from this portal in your research.

In rare cases it may be necessary to make corrections to vegetation or time series data retrospectively. The reasons for such corrections could be logger malfunctioning, wrong calculations, estimation errors, etc. Data that you have downloaded in the past may be changed in the future. Therefore, it is recommended to use the latest data available on the portal. Check the date on which the portal was last modified below.

Coordinates used in this data portal (for measurement stations and vegetation plots) are always in the coordinate system DHDN Gauss zone 5. The aerial photos are also georeferenced in this coordinate system.

Grid sampling

Soil samples were taken in a regular grid at several depths between October 2005 and April 2006 and again in 2016. Sampling depths were 0 - 30(50) cm, 30(50) - 100 cm, 100 - 150(200) cm, 150 - 200 cm and >200 cm. The samples were analyzed for grain-size distribution, pH and electrical conductivity (water extract), total content of carbon, nitrogen and sulphur, organic carbon content and lime content. The samples taken in 2016 were also analyzed for P and K content (using the double lactate method).

Nested sampling

The purpose of this sampling was to study soil development as a function of structure formation (e.g. erosion channels, vegetation, etc.). Soil samples were taken in 2008, 2011 and 2016 in the vicinity of 12 raster points (D2, D3, D5, D6, I2, I3, I5, I6, N2, N3, N5, N6) at a depth of 0 - 3 cm. The following distance classes were obtained (see figure):

- 100 m (between rows D, I and N, upper, middle and lower part of the catchment)

- 60 m (e.g., between D3 to D6)

- 20 m (e.g., between D2 and D3)

- 6 m (e.g., between 1 and 9)

- 2 m (e.g., between 11 and 15)

- 0,6 m (e.g., between 13 and 16)

- 0,2 m (e.g., between 12 and 11)
