Description: These grainsize data were collected by a BetterSize S3 Plus Particle Analyzer at the University of Virginia, organized in the spreadsheet by site. Each sample has a unique row with differential percentages of the binned grainsize data output in microns. Code to plot these data was developed by Dr. Allison Lepp and is available upon request to Dr. Marion McKenzie.

Description: This file includes columns for dry and wet weight of sediments as well as calculated moisture content in percent. Moisture content was calculated by subtracting the dry weight from the wet weight, dividing by the dry weight and multiplying by 100. Sample dry weight was collected after oven drying at 60 degrees Celsius for 48 hours.

Description: These trace element data were collected by a Niton XLF X-ray fluorescence machine (units in ppm), while magnetic susceptibility (MS) data (units in SI) were collected using a Bartington MS2 meter. Within the spreadsheet, this data is organized by site and each sample has a unique row of data. This spreadsheet also lists the difference between "field" labels (in centimeters from the beach) and "lab" labels (in centimeters from the top of the column) presented in the associated manuscript. Code to plot these data is available upon request to Dr. Marion McKenzie.

Description: This data is comprised of grain size, trace element, magnetic susceptibility, and moisture content analyses of 278 discrete sediment samples collected from outcrops in the Puget Lowland, Washington state. These samples were collected by Dr. Marion McKenzie and Dr. Lauren Miller from seven sites across Whidbey Island, Washington state in October, 2020 and processed by Dr. Marion McKenzie in the Ice and Ocean Group at the University of Virginia between October 2020 and January 2023. These samples were collected to elucidate glacial interactions with solid Earth dynamics before, during, and following the last glacial occupation of the region. Interpreted facies from these samples include sediments from glacial, glaciomarine, outwash, emergent, and submergent depositional environments. Original outcrop stratigraphy was described from bottom-to-top starting at beach-level, with the lower most units being called "Unit 1". Reference levels for height (in centimeters) are relative to the beach, and samples were taken every 10 centimeters. Upon analysis and manuscript development, these unit names were reassigned, so that the uppermost unit in each stratigraphic group was "Unit 1". The original "field" name, and new "lab" names are recorded in the file "Whidbey Island_XRFandMSdata.xlsx". Grain size analyses were conducted via a BetterSize S3 Plus Particle analyzer on sample matrix material (material ≤ 2 mm). After drying material at 60 degrees Celsius for 48 hours and homogenizing and sieving material at 125 microns, magnetic susceptibility measurements were collected with a Bartington MS2 magnetic susceptibility meter and trace element analyses were conducted on a Niton XLF X-ray fluorescence machine. While digital data and complete analyses are available within these uploaded data files, the physical data are available upon request.
