Ecological Stoichiometry Cooperative
Return to the STOICH Database Home
Complete datasets must have the data enterer's name and the date of data entry as well as the site name, the sample date, and stoichiometric measurements of organic material that include at least two of the following elements with their associated units: carbon, phosphorus, and/or nitrogen.
Columns within the STOICH data template that indicate required data contain red cells until the cells are filled. These columns are as follows:
At least two of the three following, with their associated units (indicated in yellow):
To reveal all hidden columns in the excel spreadsheet, select all of the columns and then use "Format" in the menu bar to select "Column", and click on "Unhide."
If you don't have the required data, but think your dataset is still relevant to STOICH, please email us at STOICH.project.contact@gmail.com.
If the dataset you are attempting to enter into the template contains extra data (data that doesn't fit into the template), make the comment "additional data" in the appropriate notes sections (i.e. Notes_Water) and create a new tab in the data template labeled "additional data." Add your additional data to the "additional data tab." Please include any relevant metadata.
Each color correlates to a data type (i.e. blue represents water chemistry data).
If you have both lab or experimental data as well as field data, only enter the data collected in the field into the STOICH data template.
If you have both inland and non-inland data, only enter the inland or estuarine data into the STOICH data template.
Please transform your units to match those that we have provided in the "units" column. We have provided units that are common for each type of measurement, and would like the units to remain standardized across the STOICH database for optimized user experience.
Lat or Long
If the site location information is not lat/long in decimal degrees (DD.DDDDD), use google maps (https://www.google.com/maps) to convert the current coordinate system to lat/long.
If your data has been transformed in order to standardize or correct the data to a more accurate value (i.e. due to drifting analytical equipment), please use this data, and not the raw data. Add a note in the associated note column.
In some data columns, the mean and standard deviations are accepted. However, log transformation and other similar changes to raw data are not accepted in the template. Please use only your raw data, unless your data falls under the category of "corrected data."
At least some of your stoichiometry data needs to be derived from a whole-organism or whole-body sample. The STOICH project is most interested in whole-organism or whole-resource stoichiometry. If there is partial organism stoichiometry in addition to whole-organism stoichiometry, make a note in the Stoichiometry_Origin_Organism column.
Example scenarios - multiple water samples at various depths, but single plankton tow covering the entire water column.
Solution: correlate one water sample with the single plankton sample, leave the rest of the organism samples blank to avoid replication.
Example scenarios - single water sample, but multiple plankton species measured for stoichiometry from a single tow.
Solution: correlate water sample with only one plankton species, leave the rest of the water samples blank to avoid replication.
