2. How were the data generated, processed, and modified?

   Date: Aug-2021 (process 1 of 4)

   Sediment cores were collected throughout Ozette Lake, WA during USGS field activity 2019-622-FA and 2021-641-FA using either a vibracorer (VC- labeled core ID) or a mini-hammer corer (BC- labeled core ID). Water depths were derived from high resolution bathymetry (Dartnell and others, 2024). Sediment cores were sent to PCMSC for processing and archiving. During processing VC-49 was selected and subsampled in two locations for grainsize analysis.

   Date: 18-Sep-2023 (process 2 of 4)

   GRAIN-SIZE ANALYSIS: Grain-size analysis was conducted by the USGS Pacific Coastal and Marine Science Center (PCMSC) sediment lab using a Beckman Coulter LS 13 320 particle size analyzer with an aqueous liquid module attachment. PCMSC procedures are modified from those described in Carver (1971) and Folk (1974, 1980). 5-50 grams of sediment was sub-sampled and at least 10 milliliters of 30 percent hydrogen peroxide were added to oxidize overnight to remove organics. The samples were then heated to 250 degrees Celsius to drive off excess hydrogen peroxide. Next, samples were placed in an ultrasonic bath to help disperse silt and clay (mud) from sand and larger-sized particles. Samples were then rinsed twice in deionized water with centrifugation to remove soluble ions. Subsequently, the samples were wet sieved with 1 millimeter and 0.063 millimeter sieves to segregate the combined gravel and coarse sand fraction (greater than 1 millimeter), sand (1 millimeter to 0.063 millimeter), and mud (less than 0.063 millimeter). The coarse sand + gravel fractions were then dried, dry sieved at 1/4phi intervals and weighed (Carver, 1971). The sand fraction was dried and weighed. The mud fraction was collected in a 1 liter graduated cylinder, 5 milliliters of at least 10 percent sodium hexametaphosphate (dispersant) were added, and deionized water was added to bring the total the volume to 1 liter. The mud + dispersant solution sat overnight to ensure complete dispersion and to observe if flocculation occurred. Subsequently, a 20 milliliter aliquot was extracted from the graduated cylinder and dried to obtain the mud fraction weight normalized to a 1-liter basis. The mud and sand fractions were analyzed separately via the Beckman Coulter LS 13 320 with the aqueous liquid module attachment. All size fraction data were compiled and converted by the PCMSC sediment lab pcSDSZ program (Penscil, 2015) to a grain-size distribution at 1/4phi size intervals on a weight percent basis. pcSDSZ also calculated interpolated sizes and graphical statistics on a percent coarser basis (Folk and Ward, 1957; Folk, 1966; Folk, 1974, 1980; Inman, 1952; Trask, 1930, 1932) and moment measures (Collias and others, 1963; Jaquet and Vernet, 1976; Folk, 1980).

   INTERPOLATED SIZES: Grain sizes at select cumulative percentage values (D) were calculated by the PCMSC Sediment Lab software pcSDSZ version 1.71 on a percent coarser basis, which summed from coarse to fine bins. D values were interpolated between phi bins bracketing the specified D value. Grain sizes were converted into units of millimeters (mm) using the formula mm=reciprocal of 2(exponent)phi or (phi=-log2(mm)). Interpolated grain sizes at D5, D10, D16, D25, D50, D75, D84, D90, and D95 are reported in phi and millimeter units. Person who carried out this activity:

   CARBON ANALYSIS: Carbon analysis was performed by the PCMSC carbon lab employing a coulometric titration technique described in Engleman and others (1985) and UIC operating manuals for the UIC CM5200 autosampler furnace, the UIC CM5230 acidification module, and the UIC CM5017 coulometer. Total carbon (TC), total inorganic carbon (TIC), total organic carbon (TOC) and percent calcium carbonate (CaCO3) are reported as percent dry weight. Approximately 5 grams of sediment were dried in an 80 degrees Celsius oven. Samples were then pulverized, redried, and placed in a desiccator. For TC analysis, approximately 20 milligrams of the pulverized sample were weighed and wrapped in an aluminum capsule then combusted at 950 degrees Celsius in an UIC CM5200 autosampler furnace attached to an UIC CM5017 coulometer. The carbon dioxide (CO2) produced by combusting the sample was then converted to TC by the UIC CM5017 coulometer. For TIC, approximately 20 milligrams of sample were weighed and loaded into an UIC CM5230 acidification module attached to an UIC CM5017 coulometer. The samples were then digested in a perchloric acid solution, and the CO2 generated was measured and converted to TIC. Two analyses per sample were run and the results were averaged. TOC was calculated by subtracting TIC from TC. The TIC value was then multiplied by 8.333 (the molar stochiometric ratio of CaCO3 to C) to convert TIC to percent CaCO3.

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?
   For grain-size analyses, annual service tests and daily calibrations with reference standards ensured that the Beckman Coulter LS 13 320 operated within specifications. Each sample was analyzed three times by the instrument and the data were averaged. In addition, a lab procedural duplicate was run with each batch of samples to ensure consistency and values were within 15 percent. For total carbon and total inorganic carbon analyses, duplicates were run for each sample and the results were averaged. PCMSC ensured that the instrument was within specifications by running blanks and pure, reagent-grade calcium carbonate standard before and after every 10 samples. A lab procedural duplicate was run with each batch of samples to ensure consistency and values were within 15 percent. The duplicate carbon values were within 15 percent.
2. How accurate are the geographic locations?
   
3. How accurate are the heights or depths?
   
4. Where are the gaps in the data? What is missing?
   Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
