* » Abstract |
Natural abundance levels of N and C isotopes measured in riparian plants, saltmarsh plants, suspended particulate organic matter, marine alga and Pacific Oysters in the Samish, Dosewallips, and Hamma River estuaries. Objective was to quantify the relative contribution of terrestrial, estuarine and marine C and N supporting commercial oyster populations and how this relationship varied across three river basins. |

Score | Req'd? | PKey? | » Name | Data Storage Type | Description |
---|---|---|---|---|---|
100 | No | No | Watershed | VARCHAR2 | Catchment where samples were collected. These were commercial beds located in estuaries near the confluence of each river basin. River and riparian samples collected upstream of estuary in river dominated habitat. |
100 | No | No | Site | VARCHAR2 | Where samples were collected within the catchment: oyster bed, river, saltmarsh ecosystem types. |
100 | No | No | Date_Collected | DATE | Date samples were collected. |
100 | No | No | Date_Submitted | DATE | Date samples were sent to the laboratory. |
100 | No | No | Species | VARCHAR2 | Species or sample type. |
100 | No | No | Replicate | NUMBER | Replicate within species or sample type. Units for values are count. |
100 | No | No | Delta C | NUMBER | The concentration in per mil (parts per thousands) of C13 in each sample. Studies examining stable isotopes at or near natural abundance levels are usually reported as delta, a value given in parts per thousand or per mil ("o/oo"). Delta values are not absolute isotope abundances but differences between sample readings and one or another of the widely used natural abundance standards which are considered delta = zero (e.g. air for N, At%15N = 0.3663033; Pee Dee Belemnite for C, At%13C = 1.1112328). Isotope samples with no value and "." are samples with concentrations beyond the standard values so could not be determining. Units for values are per mil or parts per thousand. |
100 | No | No | Delta N | NUMBER | The concentration in per mil (parts per thousands) of N15 in each sample. See above for more detail. Units for values are per mil or parts per thousand. |
100 | No | No | C Percent | NUMBER | The concentration percent of carbon (C) in each sample. Units for values are percentage (%). |
100 | No | No | N Percent | NUMBER | The concentration percent of nitrogen (N) in each sample. Units for values are percentage (%). |
100 | No | No | C:N | NUMBER | Ratio of percent C to N. |
100 | No | No | Length | NUMBER | Length of oyster in millimeter but caution should be taken with these data as they include fouling organisms that could not be removed. Units for values are millimeter. |
100 | No | No | Lat | NUMBER | Geospatial coordinates of sample location. Units for values are spatial coordinate. |
100 | No | No | Long | NUMBER | Geospatial coordinates of sample location. Units for values are spatial coordinate. |
100 | No | No | Weight | NUMBER | Weight of oyster in grams but caution should be taken with these data as they include fouling organisms that could not be removed. Units for values are grams. |
100 | No | No | Tissue_Type | VARCHAR2 | Oyster tissue sampled for analysis. |
100 | No | No | Ploidy | VARCHAR2 | Number of genetic chromosomes but ploidy should be used with caution because we assigned them based on their location in the oyster bed. |
