Description:

Abstract:

In September 2018, the USGS Woods Hole Coastal and Marine Science Center (WHCMSC), in collaboration with the US Army Corps of Engineers (USACE), conducted high-resolution geophysical mapping and sediment sampling to determine the distribution of historical mine tailings on the floor of Lake Superior. Large amounts of waste material from copper mining, locally known as “stamp sands”, were dumped into the laFke in the early 20th century, with wide-reaching consequences that have continued into the present day. Mapping was focused offshore of the town of Gay on the Keweenaw Peninsula of Michigan, where ongoing erosion and re-deposition of the stamp sands has buried miles of native, white-sand beaches and is steadily encroaching south onto Buffalo Reef, a large area of cobble/boulder substrate that supports productive fisheries in the lake. The objectives of this cooperative mapping project are to develop a framework for scientific research and provide baseline information required for management of resources within the coastal zone of northern Michigan. High resolution bathymetry and backscatter data reveal the irregular topography of the shallow, cobble-covered Buffalo Reef, and the relatively smooth, finer-grained sediment that covers adjacent, deeper parts of the lake floor. Previous research used numerous sediment samples to determine the general distribution of mine tailings on the lake floor in this area, but little information existed on the extent and thickness of the surficial deposits. The main priority of this project is to image the near-surface stratigraphy, specifically the surficial sand and mud that threaten to cover the reef, with seismic-reflection profiling systems. In addition to continuous coverage of bathymetric and backscatter data, this report includes a dense grid of closely spaced seismic profiles, which will guide efforts to mitigate the impacts on Buffalo Reef from contamination by the shifting stamp sands.

Purpose:

These sediment samples analyzed for grain-size composition are a primary dataset used to describe the surficial geological substrates present in the study area.

Supplemental_Information:

Data were collected using the R/V Rafael, owned and operated by the USGS Woods Hole Coastal and Marine Science Center. Additional information on the field activity is available from https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-043-FA

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigation for survey 2018-043-FA used Differential Global Positioning System (DGPS). The DGPS was set to receive fixes at a one-second interval in geographic coordinates (World Geodetic System of 1984 [WGS 84]).The recorded position of each sediment sample is the position of the DGPS antenna on the survey vessel, located on the aft of the R/V Rafael's cabin just port of the centerline, not the location of the sampler. The sampler was deployed approximately 2 meters to the starboard side of the DGPS antenna. No layback or offset was applied to the recorded position. In addition to the +/- 2-meter offset, the sampler may drift away from the survey vessel when deployed to the sea floor. Based on the various sources of horizontal offsets, a conservative estimate of the horizontal accuracy of the sediment sample locations is 2-4 meters.

The depths recorded for each sample were recorded at the time the sampler was on the bottom using the vessel's depth sounder

Process_Step:

Process_Description:

Samples submitted to the sediment analysis laboratory for grain size analysis using the Beckman Coulter Multisizer3 and sieving of the ≥ 4 phi fraction are assigned unique analysis identifiers (ANALYSIS_ID), and a macro-enabled Microsoft Excel data entry spreadsheet (GrainSizeWorksheet_WB01.xlsm, where WB01 is the batch number assigned to the sample submission) is created to record the measurement data. About 50 grams of wet sediment are placed in a pre-weighed beaker, weighed, oven dried at 100°C, and reweighed to correct for salt. The dried sample is wet sieved through a 0.062 mm (No. 230) sieve. The coarse fraction remaining in the sieve is oven dried at 100°C (until completely dried) and weighed. The fine fraction in water is collected in a plastic Nalgene bottle and sealed with a screw lid (stored for no longer than one week). The coarse fraction is dry sieved to determine the individual weights of the 4 to -5 phi fractions, and the weights are recorded in the data entry spreadsheet. At the request of the submitter, shell and shell fragments can be manually removed from the -2 phi and coarser fractions, weighed and their weights are recorded in the data entry spreadsheet. The fine fraction is run and combined using the 200 μm and 30 μm Coulter analyses using the Multisizer3 software to get the fine fraction grain size distribution. The fine fraction distribution data are added to the data entry spreadsheet. The spreadsheet is used to calculate a continuous phi class distribution from the original fractions.

Process_Description:

Continuous phi class distribution from the original fractions are transposed to the "results" tab in the macro-enabled Microsoft Excel data entry workbook (GrainSizeWorksheet_WB01.xlsm, where WB01 is the identifier assigned to the sample submission). Macros in the workbook ("GS_statistics" and "sedimentname") are run to calculate grain size classification and statistical analyses and finish processing the data. Sample, navigation, and field identifiers, along with continuous phi class distribution data, grain size classification, and statistical analysis results are copied and pasted into a final Microsoft Excel spreadsheet (WB01_GS-MS_results.xlsx, where WB01 is the batch number assigned to the sample submission). The processed data are quality control checked and assigned a quality grade based on the examination of the analytical data. Processed data are released to the submitter and incorporated into the laboratory's database. All raw analytical data generated by the samples are archived in the sediment analysis laboratory.

Attribute_Label: QUALITY GRADE
Attribute_Definition:

Samples are assigned a quality grade based on the examination of the analytical data. Data quality grades may be determined by several factors, and any comments or notes that indicate the data for a particular sample may be suspect are included in the results table for that sample under "comments". Quality grades for sample data that do not have any additional comments are assigned based on the calculated percent difference between the weights of the coarse fraction remaining after wet sieving and the sum of all of the weighed fractions after dry sieving the coarse fraction, indicating an estimated differing amount of material which could skew the calculated grain size results: A = percent differences between 0% and ±1.5%, B = percent differences between ±1.5% and ±3%, C = percent differences between ±3% and ±4.5%, and D = percent differences greater than ±4.5%.
