Online-Only Table 8.
The associated environmental data for each salmon or prey sample.
| Column | Explanation |
|---|---|
| environmental_data_id | A unique number that is generated and assigned to each environmental data point |
| source_id | This number corresponds with the source_id from Online-only Table 2 |
| year_min | YYYY; if there is just one value for the year then it is found in this attribute; if there are a range of values for the year then the minimum value is found in this attribute |
| year_max | YYYY; if there are a range of values for the year then the maximum value is entered into this attribute |
| warm_cool_years | Either ‘warm’, ‘cool’ or NA; this attribute will only have a value if the samples are explicitly reported as being from a warm versus cool year(s) and can only be uniquely identified this way |
| odd_even_years | Either ‘odd, ‘even’ or NA; this attribute will only have a value if the samples are explicitly reported as being from an odd versus even year(s) and can only be uniquely identified this way |
| season_min | Either ‘spring’, ‘summer’, ‘autumn’, or ‘winter’; if there is just one value for the season then it is entered into this attribute; If there are a range of values for the season then the minimum value is entered into this attribute; this attribute will only have a value if there is no value for the month/date and the source explicitly defines the temporal sampling period by season |
| season_max | Either ‘spring’, ‘summer’, ‘autumn’, or ‘winter’; if there are a range of values for the season then the maximum value is entered into this attribute; this attribute will only have a value if there is no value for the month/date and the source explicitly defines the temporal sampling period by season |
| month_min | Month names are completely spelled out with the first letter capitalized; if there is just one value for the month then it is entered into this attribute; If there are a range of values for the month then the minimum value is found in this attribute |
| month_max | Month names are completely spelled out with the first letter capitalized; if there are a range of values for the month then the maximum value is found in this attribute |
| date_min | Expressed using year, month, and day; if there is just one value for the date then it is entered into this attribute; if there are a range of values for the date then the minimum value is found in this attribute |
| date_max | Expressed using year, month, and day; if there are a range of values for the date then the maximum value is found in this attribute |
| time_min | HH:MM:SS; if there is just one value for the time then it is found in this attribute; if there are a range of values for the time then the minimum value is found in this attribute |
| time_max | HH:MM:SS; if there are a range of values for the time then the maximum value is found in this attribute |
| lat_min | If there is just one value for the latitude then it is found in this attribute; if there are a range of values for the latitude then the minimum value is found in this attribute; values are in decimal degrees format |
| lat_max | If there are a range of values for the latitude then the maximum value is found in this attribute; values are in decimal degrees format |
| lon_min | If there is just one value for the longitude then it is entered into this attribute; if there are a range of values for the longitude then the minimum value is entered into this attribute; values are in decimal degrees format |
| lon_max | If there are a range of values for the longitude then the maximum value is found in this attribute; values are in decimal degrees format |
| environmental_data_type | The environmental data type reported in the source (e.g., temperature, salinity) |
| measurement_depth | The depth associated with the environmental parameter measurement; if the measurement in reported to be at the surface (e.g., sea surface temperature) then the measurement depth value is assigned to 0 |
| depth_units | The units associated with the measurement depth; units are fully spelled and plural (e.g., meters instead of meter) |
| environmental_subsample_id | A unique number that is generated and assigned to environmental samples if there are no other unique identifiers; values are assigned for each source starting from 1 and increasing by a value of 1 each time (e.g., 1,2,3…) |
| environmental_notes | Any additional comments on the environmental parameter measurement |
| value | The value of the environmental parameter |
| mean | The mean of the environmental parameters |
| error | The error associated with the environmental parameter mean |
| min | If there are a range of values for the environmental parameter this attribute represents the minimum value |
| max | If there are a range of values for the environmental parameter this attribute represents the maximum value |
| environmental_units | The units associated with the environmental parameter; units are fully spelled and plural (e.g., micrograms per liter instead of microgram per liter) |
