Online_Linkage: https://doi.org/10.5066/P9LOCE8T Description: Abstract: Eelgrass (Zostera marina) characteristics, sediment grain size distributions, sediment total organic carbon contents (TOC), carbon isotope ratios of sediment organic matter, and total carbon to total nitrogen ratios were measured at four lower intertidal sites in Bellingham Bay, Washington, July 2-5, 2019. Purpose: Eelgrass and substrate were characterized along the urban waterfront (east shore) of Bellingham Bay, Washington, to explore influences of alongshore gradients in wave energy and shoreline development and distance from sources of Nooksack River sediment and terrestrial organic matter. These data were collected to inform site selection for future interdisciplinary studies about the role of eelgrass in wave-energy attenuation, particle trapping, biodiversity, and contaminant exposure.

Browse_Graphic_File_Type: JPG Data_Set_Credit: Angela Tan measured sediment grain-size distributions and total organic carbon contents at the USGS Pacific Coastal and Marine Science Center Sediment Laboratory. Colin Carney at the University of California Santa Cruz Stable Isotope Lab measured stable carbon 13/12 isotope ratios and total carbon to total nitrogen ratios. Native_Data_Set_Environment: Eelgrass and sediment data are tabulated in comma separated variable (CSV) format. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: GRAIN SIZE: Duplicate grain-size determinations by weight differed by 0 to 9 percent with a median of 2 percent in similar samples from Bellingham Bay. TOTAL ORGANIC CARBON (TOC): Duplicate determinations of TOC differed by 0 to 26 percent with a median of 3 percent in similar samples from Bellingham Bay. STABLE CARBON ISOTOPE RATIOS (d13C): The analytical precision of d13C ratios relative to internationally calibrated in-house reference materials is better than 0.2 permil. CARBON TO NITROGEN RATIOS (C:N): Precision of C:N relative to reference materials of known composition is better than 1 percent. Logical_Consistency_Report: No formal logical consistency tests were conducted. Completeness_Report: Plant characteristics were measured in 10 quadrats across 100-meter-long transects except at Taylor Bridge where the transect was 85 meters long. Sediment characteristics were measured in 3 quadrats at the beginning, middle, and end of each transect. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A Garmin handheld GPS reported a horizontal accuracy of 3 meters. Lineage: Process_Step: Process_Description: SEDIMENT COLLECTION: The surface 0-2 centimeters of sediment was scooped by hand at the beginning, middle, and end of lower intertidal transects where eelgrass was characterized. Sediment was stored chilled until analysis. Process_Date: 20190705 Process_Step: Process_Description: SEDIMENT GRAIN-SIZE AND TOTAL ORGANIC CARBON CONTENT (TOC): Sediment particle size distributions were determined at the USGS Pacific Coastal and Marine Science Center sediment laboratory. To remove organic material, 10 milliliters of 35 percent hydrogen peroxide were added to 20 grams of sediment. The sample was heated to 250 degrees Celsius to remove any remaining hydrogen peroxide and was placed in an ultrasonic bath to liberate the less than 0.063 millimeter-diameter (fine) fraction. The sample was centrifuged for 1.5 hours in deionized water to remove soluble salts. Samples were funneled while wet through 2-millimeter and 0.063-millimeter mesh sieves to separate gravel-sized (greater than 2 millimeter), sand-sized (0.063 to 2 millimeter), and mud-sized (less than 0.063 millimeter) particles. The sand and gravel fractions were dried at 80 degrees Celsius and weighed. Five milliliters of sodium hexametaphosphate was added to the mud fraction and a 20 milliliter aliquot was taken from a 1 liter graduated cylinder to determine the weight of the mud. Total carbon and total inorganic carbon of bulk sediment were determined coulometrically (UIC, Inc.) at the USGS Pacific Coastal and Marine Science Center Sediment Laboratory. Samples were run in duplicate. Coulometer performance was verified relative to a calcium carbonate reference material. Total organic carbon content (TOC) was calculated as the difference between total carbon and total inorganic carbon.

A decarbonation pre-treatment step consisting of fumigation with sulfurous acid removed inorganic carbonates. Stable isotope ratios were corrected for size, drift, and source stretching effects. d13C values were referenced to the Vienna PeeDee Belemnite.

Eelgrass stems with fully formed sheaths at the sediment surface were counted as individual shoots. Alongshore transect lengths were 100 meters at Marine Park, Boulevard Park West, and Boulevard Park North, and 85 meters at Taylor Bridge. In-field shoot counts were normalized to 1 square meter. Process_Date: 20190705 Process_Step: Process_Description: EELGRASS LEAF LENGTH, WIDTH, AND NUMBER- Eelgrass plants with the longest intact leaves inside or adjacent to quadrats were harvested in their entirety, including as much of the subterranean rhizome as could be recovered. Lengths of the longest leaf on harvested plants were measured from the top of the sheath to the tip. Widths of the second-newest leaf on harvested plants were measured 5 centimeters above the sheath. Numbers of leaves in the sheathes of harvested plants, excluding leaves of daughter shoots, were recorded. Process_Date: 20190705 Process_Step: Process_Description: EELGRASS INTERNODE LENGTH- Distances between rhizome nodes were measured sequentially on the main rhizome stem using a digital caliper with a resolution of 0.01 mm (Fowler). Rhizome segment 1 is the newest fully formed rhizome with erupted root bundles. Process_Date: 20190705 Process_Step: Process_Description: EELGRASS DRY BIOMASS- After collection, eelgrass leaves were rinsed with tap water and scraped with a razor blade to remove epiphytic organisms. Eelgrass rhizomes were rinsed with tap water to remove sediment and epiphytic organisms. Eelgrass shoots and rhizomes were separated at the meristem, daughter plants were removed from shoots and rhizomes, and plants were stored moist for less than 1 week. Shoots and rhizomes were dried at 60 degrees Celsius for at least 24 hours and weighed to the nearest 0.001 gram.
