Abstract:

We grew Ruppia maritima in a range of manipulated sediment oil concentrations: 0, 0.26, 0.53, and 1.05 mL oil /L tank volume. This dataset reports the initial and final wet weight, shoot density, shoot length, inflorescence, seed production, root characteristics, and uprooting force of plants for 12 replicates of each treatment. Each replicate contained 3 plants. Alkane and aromatic concentrations for each treatment are included. Additionally, soil cohesion was measured weekly at the same oil concentrations and is reported as force needed to remove plastic beads from sediment. All plants were grown in 19L tanks in the Louisiana State University greenhouse facility.

Purpose:

The dataset was developed to determine growth, reproduction, and uprooting of Ruppia maritima in oil-contaminated sediments

Data Parameters and Units:

Attached information includes initial and final plant stem counts, fruits, inflorescence, weight (g), stem lengths (cm), and final uprooting strength (g force). Note that each column after the "stem length" column in the Initial Plant Measurements and Final Plant Measurements worksheets also report individual stem lengths. Additional information includes root measurements for mass (mg), length (mm), area (mm^2, volume (mm^3), and density of roots (mg/mL). Oil analyses include: Initial sediment weight (mg); Final extract volume (ml); Field ID# (none= 0 mL of oil, low= 5 mL of oil, med= 10 mL of oil, high= 20 mL of oil); Surrogate corrected aromatic/alkane concentration (ug/g and ng/g). Chemical analyses of tanks and force measurements (g force) for a second experiment to test the force needed to remove plastic beads from sediments are also reported.

Methods:

Plants were grown in 19L tanks in the LSU greenhouse facility and the aforementioned variables measured.
