Supplement – data (viewable) used in the meta-analyses
E080009.txt – data (downloadable) used in the meta-analyses in comma-delimited ASCII-format. This file also includes variable header information that must be removed with a text-editor prior to parsing the data.
This supplement contains the data-set used to perform the meta-analyses of marine nutrient-enrichment experiments. References referred to are listed in the reference list of the manuscript noted above.
Variable codes in the data file are:
| R# | Reference number on the authors' master reference list. |
| Reference | Author and year of publication of reference. Whole references are listed in published article. |
| Latitude | Approximate latitude at from which water samples were obtained. Negative latitudes are south of the equator. |
| Area | Site indicator describing the place from which samples were collected. |
| Site | A second site or date indicator to distinguish experiments run near the same location. |
| key | A third site or date indicator to distinguish experiments run near the same location. |
| treatment | Labels indicate the nutrient addition used to obtain the response shown in later columns. |
| Control Biomass | Phytoplankton biomass in the control vessels for at least one of the experiment durations, if multiple durations were employed. |
| Treatment Biomass | Phytoplankton biomass in the vessels receiving nutrient ammendments for at least one of the experiment durations, if multiple durations were employed. |
| Response Ratio | The average response ratio seen for all experimental durations between 2 and 7 days (see legend of Fig. 1). |
| delta r | The average delta-r value seen for all experimental durations between 2 and 7 days (see Eq. 2). |
| Nutrient Code |
Code describing the degree of nutrient pollution prevalent at the site where water samples were obtained. These data were derived from information given by the authors of the studies. 1=Very polluted with nutrients 2=Moderately nutrient polluted 3=Lightly nutrient polluted 4=Unpolluted 5=Pristine 6=Polluted with high N:P nutrients |
| Environment Code |
Code describing the type of marine environment where water samples were obtained. These data were derived from information given by the authors of the studies. 1=Estuarine 2=Harbors, Bays, Canals 3=Nearshore, Coastal but not enclosed 4=Large Sounds and landlocked Seas 5=Shelf 6=Oceanic |
| Entry Order | A locator code used to identify the origins of specific entry records. |
