Soil pH: Long-Term Nitrogen Deposition During Grassland Succession
The purpose of this experiment is to measure how initially disturbing an area and adding nitrogen over a long time will affect the number of species, the type of species present, the amount of annual growth, and the change from year to year in the growth of each species in a plant community which is also relieved of grazing by large and small mammals. This experiment is conducted within fields (A, B, and C) which were initially low in soil nutrients. The ground was disturbed by thoroughly disking the area prior to establishment of the experiment. There are 8 different levels of nitrogen addition with other nutrients added to ensure that nitrogen remains the limiting nutrient, and a control which receives no nutrients. Nitrogen fertilizer (NH4NO3) is applied twice per year, once in early May and once in late June. There are six replicates of each treatment per field. The treatments were randomly assigned to plots of size 4 by 4 meters. The plots are in 6 plot by 9 plot grids with 1 meter aisles between plots. The plot grids are enclosed by a fence to keep out mammalian herbivores. Gophers are trapped and removed as they appear. In the spring of 1992, subexperiments E097 and E098 were established. E097 is in fields A and C where randomly selected plots within each treatment no longer receive fertilizer. E098 is in field B where randomly selected plots within each treatment are burned. Note that the design of E002 is similar to E001 except E002 was thoroughly disked prior to establishment.
Root Carbon and Nitrogen: Long-Term Nitrogen Deposition: Population, Community, and Ecosystem Consequences
The purpose of this experiment is to measure how adding nitrogen over a long time will affect the number of species, the type of species present, the amount of annual growth, and the change from year to year in the growth of each species in a plant community which is also relieved of grazing by large and small mammals. The experiment is being conducted within fields (A, B, C, and D) which were initially low in soil nutrients. There are 8 different levels of nitrogen addition with other nutrients added to ensure that nitrogen remains the limiting nutrient, and a control which receives no nutrients. There are 6 replicates of the 9 treatments in fields A, B, and C and 5 replicates in field D. The treatments were randomly assigned to the plots. In fields A, B, and C the plots are in 6 by 9 grids and are 4 by 4 meters in size with 1 meter aisles between plots. In field D the plots are 1.5 by 4 meters and are placed in a 3 by 17 grid.

Shrub survey:Effects of Long Term Fertilization and Oak Canopy Cover on Plant Communities and Ecosystem Processes
In 1996 E142 was established in field D on top of the E004 macroplots. E004 was conducted in fields A, B, C and D by Dave Tilman. The purpose of E004 was to see what effect NH4NO3 addition has on large areas over a longer period of time with exposure to naturally-occurring levels of herbivory. The nutrient addition treatments in E004, E142 plots have been applied annually since 1982. These experiments, along with others at Cedar Creek, examine the community and ecosystem consequences of chronic nutrient loading.

Gull Lake long-term Microcystis monitoring at the Kellogg Biological Station, Hickory Corners, MI (1998 to 2014)
Dataset Abstract This dataset consists of 13 years of observations of Microcystis biomass and microcystin in an oligotrophic lake (Gull Lake, MI, USA), where it is promoted by invasive zebra mussels (Dreissena polymorpha). Annual means are reported for all variables. As originally published, the data were used to assess the influence of interannual variation in water temperature and zebra mussel mortality on Microcystis dynamics in an oligotrophic lake original data source http://lter.kbs.msu.edu/datasets/165
McMurdo Dry Valleys Glacier melt modeling: Long Wave Radiation 1996-2011
This is the data and metatada for modeled Long Wave Radiation - part of six modeled parameters that comprise the Taylor Valley Galcier Melt modeling Data contained and described in this document correspond to the physically-based surface energy balance model for the glaciers of Taylor Valley developed by the dataset owners. The spatial variability in ablation (ice melt and sublimation), runoff, and climate sensitivity of the glaciers was modeled using 16 years of meteorological and surface mass balance (the net mass gain or loss of ice on the surface of the glacier) observations collected in Taylor Valley (see figure). Â An unusual aspect of the model is the inclusion of transmission of solar radiation into the ice and subsequent drainage of some subsurface melt . Â Melt model was applied to the ablation zones of the glaciers of Taylor Valley, identified by colored areas. Mass balance stakes, meteorological stations, and stream gages shown for reference. These output files are part of a multi set comprising 5 outputs and one input dataset. Â The input dataset package is at http://mcmlter.org/content/glacier-melt-modeling-inputs-and-example-m-fi...
Congruence checks for EML-described datasets in the Long Term Ecological Research (LTER) Network, Checks described as of 2015
These data are descriptions of all checks contributed to the LTER EML Congruence Checker as of late 2015. The EML Congruence Checker (ECC) informs contributors about the structure of the data package, indicating whether the asserted metadata accurately defines the data entity (table); this is called “structural congruence”. The checks and checking software are discussed in O'Brien, M. C, D. Costa and M. Servilla. 2016. Ensuring the quality of data packages in the LTER network data management system. Ecological Informatics. DOI: 10.1016/j.ecoinf.2016.08.001. Data are organized into a flat table, with one row per check. Each check is characterized with multiple typologies including priority, justification, scope (community), response behavior type and data packaging aspect. Operational information for software includes EML path, criteria for pass/fail, response expected, sample datasets for both pass and fail responses, with failure notes. Management fields indicate if the check has been implemented or not (as of paper publication), with dates when the check was added or updated.
