Abstract:
This is a report of geochemical data from various media collected on Isle Royale, a large island in northeastern Lake Superior. Isle Royale became a national park in 1940 and was designated as a wilderness area in 1976. USGS sampling began in 1996 as part of a larger project on the Midcontinent Rift in the Lake Superior region. Data are given in nine Microsoft Excel spreadsheets. All the data are newly acquired by the USGS.
Purpose:
USGS sampling on Isle Royale began in 1996 as part of a larger project on the geology of the Midcontinent rift in the Lake Superior region and continued through 2000. Sampling began with collecting bedrock samples to characterize the geochemistry of the volcanic rocks that make up the much of the island, as well as samples representative of the minor native copper mineralization found on the island. Preliminary results from the bedrock study indicated, among other findings, that basaltic bedrock on the island had no detectable mercury, but that there was an association between native copper mineralization and trace amounts of mercury (Cannon and Woodruff, 1999). This finding and the recognition by the National Park Service that 6 of 32 inland lakes on Isle Royale have mercury levels in game fish that exceed State of Michigan acceptable levels for human consumption (Kallemeyn, 2000) resulted in renewed sampling on the island focused more on environmental issues.
To evaluate atmospheric inputs of mercury and other elements to soil geochemistry, regionally distributed samples of both soils and lichens were collected as paired samples across the entire island. At each soil sample site, three epiphytic (grows in trees) lichen species, Evernia mesomorpha, Hypogymnia plysodes, and Parmelia sucata, were always collected. At some sites Cladina rangiferina, a lichen that grows on bare bedrock and soil surfaces, was also collected. The occurrence of Cladina rangiferina on the island is more limited, and so this lichen species was not collected at all sites
A high density of soil samples was collected within three individual watersheds (Sargent Lake, Lake Wagejo, and Lake Richie) for a more localized study that evaluated the terrestrial distribution of mercury and other elements of environmental concern. These lakes were chosen using data from Kallemeyn (2000) that showed that Sargent Lake and Lake Wagejo have high mercury in fish, whereas Lake Richie, which is similar in size to Sargent Lake, does not. As part of this study on the terrestrial contribution of mercury to lakes, long cores of lake sediments were recovered from Sargent Lake and Lake Richie using a modified Livingston piston sampler.
For an ancillary study that evolved from the study on the distribution of mercury in certain watersheds, some soil samples were collected to evaluate the impact of forest fire on soil geochemistry, deliberately sampling within and outside areas on the island that burned in severe forest fires in 1936. To complete bedrock sampling on the island, rock samples from the Copper Harbor Formation, a sedimentary unit that occurs on the southeastern part of the island were collected in 1999.

USGS ANALYSES -- Samples analyzed by the U.S. Geological Survey includes all analyses contained in the data files Volcanic_bedrock.xls, Sedimentary_bedrock.xls, Mineralized_rock.xls, A_horizon.xls, C_horizon.xls, Sargent_Lake_core.xls, and Lake_Richie_core.xls. Analytical results were compared to results for standard reference materials. Data quality checks were performed both at an analytical laboratory (XRAL) and by the USGS. The first level of quality control checks occurred at XRAL. XRAL Laboratories is accredited to the ISO 9002, 1994 standard (ANSI-RAB 01298 and NACB 9555). The laboratory's quality control protocol is to insert a reagent blank and a reference sample material with every batch of 20 samples to measure the analytical accuracy. Duplicate samples are analyzed at the end of the sample set to measure analytical variance as well as sample variance. Data passing the quality control criteria was sent to the USGS and imported into the Laboratory Information Management System (LIMS).
The second level of data validation was performed at the USGS. All samples submitted to XRAL are accompanied with a set of USGS in-house reference samples submitted at the rate of 10%. Using a program within the LIMS, the data for the reference samples was evaluated by comparing the "obtained" analytical value to the "expected" value for each element. The values must fall within the range of acceptance, which varies between +/- 5% to +/-20% depending on the analytical method.
UNIVERSITY OF WISCONSIN ANALYSES -- Samples analyzed by Soil and Plant Analysis Laboratory, University of Wisconsin, Madison, Wisconsin include O_horizon.xls and Lichen_xls. Analytical results were compared to results for standard reference materials. The first level of quality control checks occurred at the Soil and Plant Analysis Laboratory through the use of duplicates, blanks, and reference standards.

Process_Description:
Sample collection:
Geochemical sample media include bedrock, mineralized rock, lake sediments, different soil horizons and four species of lichens (Figures 2 and 3). Because of restrictions on sampling within a wilderness park, rock samples were collected from mine dumps or loose blocks obviously fallen from outcrop. All rock samples were trimmed in the field to remove weathered material, and further trimmed and hand selected during preparation to minimize contribution from weathered or altered surfaces. Samples of native copper mineralized rock typically were composite chip samples collected from mine dumps. Descriptions recorded in the field are included in the data files.
Reconnaissance soil sample sites typically were from upland areas. Within the Sargent Lake and Lake Richie watersheds both upland and lowlands (but not wetland) sites were sampled. Soil samples were collected from soil pits dug with a shovel and extended with a hand auger. Sample pits were completed to the C-horizon or to a depth dictated by the presence of impenetrable rock. From each pit, soil from different horizons was collected so that each sample site has multiple geochemical analyses, each representing a different soil layer. All samples were stored in perforated polyethylene bags (Hubco Tyvek®). During the first year of soil sampling, which concentrated within the Sargent Lake and Lake Wagejo watersheds, material from the O-horizon was not collected.
The O-horizon is the organic matter that lies on top of a mineral soil. The organic layer is divided into Oi (forest litter), Oe (forest duff) and Oa (humus) horizons. Forest litter is not decomposed, and contains identifiable dead plant material. Forest duff is partially decomposed organic material that may underlie the litter layer. Humus is completely decomposed, non-identifiable organic material. At each soil sample site, with the exceptions noted above, Oe-horizon material was collected, if available. Field descriptions discriminate between forest litter that is not decomposed and more decomposed forest duff, but do not attempt to distinguish duff from humus. Samples from Oe-horizons typically were grab samples collected from the soil plug removed from the sample pit. Litter material, when collected, was composited from material in the area of the sample site. The nature of the original material (e.g., needles versus leaves) was noted, as were the dominant tree species.
The upper mineral soils typically were classified as A-horizon, indicating some accumulation of organic carbon, and were distinguished from underlying soil horizons by changes in color. A-horizon soils were collected from most sample sites, with material composited from the entire thickness of the horizon. At some sites, a very thin A-horizon overlay an E-horizon, a zone of eluviation, easily distinguished by its light, buff or gray color. A limited number of E-horizon samples were also collected when little or no A-horizon soil was present.
Subsoil samples typically were composed of weathered parent material, which, on Isle Royale, is either bedrock or glacial deposits on bedrock. The depth of collection for C-horizon soil samples in areas of thin glacial cover typically was constrained by the depth to bedrock, with samples collected immediately above the bedrock surface. In areas of thick glacial cover, collection depths usually were 60 80 cm, which typically was the depth to parent glacial material. In a few cases, multiple samples were collected when obvious changes in color or texture were noted.
Lichen samples were collected by hand from trees in the immediate vicinity of soil sample sites and from bedrock, if available. The three epiphytic lichen species collected, Evernia mesomorpha, Hypogymnia plysodes, and Parmelia sucata, are easy to identify in the field and do not require chemical tests for identification. Each lichen species was picked separately and cleaned as well as possible in the field. Epiphytic lichens were collected without gloves only from evergreen species, with one exception in a hardwood maple forest where no evergreen trees were present. At a site, all three species were collected from multiple individuals of a single tree species (e.g., white spruce or balsam fir), but the single tree species varied from site to site, depending on availability. The result of this sampling method is collection of multiple thalli representing an aggregate sample from several trees in an area. Picking extended from near ground level to as high as could be reached when standing on the ground, approximately 1.5 2 meters. Lichens picked from dead or downed trees may have originally been higher in the air prior to tree mortality and are so noted. Cladina rangiferina was collected from bedrock surfaces by hand. Only fresh, apparently healthy lichen were picked in the field. At each site, about 20 grams of lichen was stored in perforated polyethylene bags (Hubco Tyvek®). Samples were air dried to ambient moisture levels prior to shipping to the USGS National Wildlife Health Center in Madison, Wisconsin for analysis.
Lake sediment samples from Sargent Lake and Lake Richie were collected using a modified Livingston piston sampler (Wright, 1967). To obtain the cores, researchers from the USGS flew to Isle Royale in the winter of 1999 in a U.S. Forest Service Beaver seaplane, landing on the ice of each lake. Lake sediment core was obtained through the ice from near the deepest part of each lake, using lake bathymetry maps as guides. The coordinates for the site on Sargent Lake are: latitude 48.0820; longitude 88.6548. The coordinates for the site on Lake Richie are: latitude 48.0420; longitude 88.6930. Care was taken to sample from areas away from shore and where the lake bottom was relatively flat. At each lake the coring procedures were similar. After augering a hole through the ice, the depth of the water was measured with a Vexilar® portable sounder. Core was recovered through 11 meters of water in Sargent Lake and 9.75 meters of water in Lake Richie. To obtain the first core from an undisturbed bottom, the piston core apparatus was lowered to the sediment/water interface (using 2 meter extension drive rods) and then advanced the depth of the 1 meter core barrel. Prior to removing the piston corer, a sleeve of 15 cm (diameter) PVC was assembled and lowered through the hole in the ice around the drive rods and piston corer to act as a casing and guide for successive cores. The casing was pushed about 30 cm into the lake bottom to provide a firm anchor. With the casing in place, the piston corer was removed, and the 1 meter core extracted. Each core was immediately wrapped in plastic and aluminum foil and stored in a core box. The piston corer was then reintroduced into the original hole through the casing, and advanced another length of the core barrel (1 meter). The procedure was repeated until 5 meters of core were collected from Sargent Lake and 6 meters of core were collected from Lake Richie. Visual inspection of the cores as they were removed suggested little or no slumping in the borehole, although some compaction in the core was apparent. The length of available drive rods limited the length of core recovery at Sargent Lake, but at Lake Richie coring ended when advancement of the core barrel through compacted sediment was no longer possible. Both sets of long cores were split lengthwise immediately following fieldwork, and one half was preserved and the other half was further split for geochemical analysis

Process_Description:
Sample preparation:
Rocks: Rocks were crushed to 0.5 cm fragments in a jaw crusher and fed into a ceramic plate pulverizer where fragments were reduced to approximately minus 100-mesh. Each pulverized sample was split, with a portion submitted for geochemical analysis and a portion archived. Clean quartz rock and sand were crushed and pulverized between samples to minimize cross-contamination.
Soils: Soil samples were air-dried and disaggregated in a soil grinder, if necessary. Samples were then sieved to <63 micrometers prior to analysis. Samples were not ground.
Lake Sediment Cores: The top meter of core from each lake was composited in 5 cm intervals. Samples from the remaining cores from each lake were collected in 2 cm intervals every 10 cm. Splits were placed in trace-element-free cardboard cans and dried overnight in a 50o C oven. Prior to analysis, samples were completely pulverized in a shatter-box.
Lichen and O-horizon: Upon arrival in Madison, Wisconsin, lichens and O-horizon organic material were extracted from the bags. Lichen samples were manually cleaned of debris, bark, and other foreign matter. Handling of tissue was with bare hands, which were washed between samples. Hand contact with tissues was only a few seconds for each thallus. Two to four grams of cleaned samples were placed in clear plastic bags and labeled for chemical analyses. Both lichen and O-horizon samples were ground to a powder in a stainless steel Wiley ED-5 mill using a 2 mm screen. After grinding the samples were placed in plastic vials and either stored in a desiccator or re-dried just prior to weighing for analysis.

Inductively Coupled Plasma-Atomic Emission Spectroscopy.
Forty major, minor, and trace elements are determined in geological materials by inductively coupled plasma-atomic emission spectrometry (ICP-AES). The sample is decomposed using a mixture of hydrochloric, nitric, perchloric, and hydrofluoric acids at low temperature. The digested sample is aspirated into the ICP-AES discharge where the elemental emission signal is measured simultaneously for the forty elements. Calibration is performed by standardizing with digested rock reference materials and a series of multi-element solution standards.
The 40 elements analyzed are listed below with their reporting ranges. For samples containing less than the lower limit of detection, the notation b.d. (below detection) is entered into the value field.

MERCURY ANALYZED BY CONTINUOUS FLOW-COLD VAPOR ATOMIC ABSORPTION SPECTROMETRY For determination of mercury a 0.1g of sample is digested using a mixture of nitric and hydrochloric acids. Potassium permanganate, sulphuric acid and potassium persulphate are added to the solution, followed by a NaCl-hydroxylamine solution and then the solution is diluted to 25mL. It is mixed thoroughly, allowed to settle and then transferred to the auto sampler rack of the Perkin-Elmer Flow Injection Mercury System, FIMS-100. The FIMS-100 is a cold-vapor atomic absorption mercury analyzer, which determines the mercury concentration in a solution after it has been liberated as vapor using stannous chloride reducing agent. The absorption of the sample is measured using a mercury lamp at 253.7nm. The lower reporting limit of 0.02 ppm mercury. Samples containing less than 0.02 ppm are assigned a value of 0.01 in the data tables.
ARSENIC ANALYSIS BY ATOMIC ABSORPTION SPECTROPHOTOMETRY Arsenic was determined by weighing 0.1 g of sample into a zirconium crucible. Approximately 0.75 g of sodium peroxide is added and mixed. The mixture is heated in a muffle furnace set at 750°C for four minutes. The sample is cooled then 15 ml of water and 5 ml of concentrated HCl is added. The mixture is shaken and 0.25 ml of an ascorbic acid KI solution is added then diluted with 20% HCl and let to stand overnight. Arsenic is then measure using hydride generation atomic absorption spectrometry. The optimum concentration range without sample dilution is 0.6 ppm to 20 ppm.
SELENIUM ANALYSIS BY ATOMIC ABSORPTION SPECTROPHOTOMETRY Selenium is determined by weighing .25 g of sample into a test tube, adding a mixture of nitric, hydrofluoric and perchloric acids and heating. After the solution is cooled hydrochloric and nitric are added, heated again and cooled. The samples are diluted and analyzed using hydride generation atomic absorption spectrometry. The expected analytical range for selenium is 0.2 to 4 ppm.
TOTAL CARBON ANALYSIS BY AUTOMATED CARBON ANALYZER Total carbon is determined by the use of an automated carbon analyzer. A weighed sample is combusted in an oxygen atmosphere at 1370°C to oxidize carbon to carbon dioxide. Moisture and dust are removed and the carbon dioxide gas is measured by a solid state infrared detector.
CARBONATE CARBON ANALYSIS BY COLUMETRIC TITRATION Carbonate carbon is determined as carbon dioxide by coulometric titration. The sample is treated with hot 2N perchloric acid and the evolved carbon dioxide is passed into a cell containing a solution of monoethanolamine. The carbon dioxide, quantitatively absorbed by the monoethanolamine, is coulometrically titrated using platinum and silver/potassium-iodide electrodes. The lower reporting limit is 0.01% carbon dioxide and samples containing up to 50% carbon dioxide may be analyzed. Sample size is adjusted from 0.5 g for the range 0.01 to 5% carbon dioxide, 0.1 g for the range 5 to 10% carbon dioxide, and 0.02 g for greater than 10% carbon dioxide
Organic carbon is calculated as the difference between total carbon and carbonte carbon,
TOTAL SULFUR ANALYSIS BY AUTOMATED SULFUR ANALYZER Total sulfur is determined by using an automated sulfur analyzer. Approximately 0.25 g of sample is mixed with iron chips and LECOCEL and is heated in a combustion tube in a stream of oxygen at high temperature. Sulfur is oxidized to sulfur dioxide. Moisture and dust are removed and the sulfur dioxide gas is then measured by a CS-244 infrared detector.
WAVE-LENGTH DISPERSIVE X-RAY DIFFRACTION (WDXRF) Ten major elements were determined in rocks by wavelength dispersive X-ray fluorescence spectrometry. The sample is first ignited, then fused with lithium tetraborate and the resultant glass disc is introduced into a wavelength dispersive X-ray spectrometer. The disc is irradiated with X-rays from an X-ray tube. X-ray photons emitted by the elements in the sample are counted and concentrations determined using previously prepared calibration standards. In addition to 10 major elements, the method provides a gravimetric loss-on-ignition.
The reporting ranges for WDXRF are:

MnO 		0.001
INSTRUMENTAL NEUTRON ACTIVATION BY LONG COUNT (INAA) Some trace elements in rocks were analyzed using instrumental neutron activation analysis. INAA selectively measures radioactive nuclide activity produced by nuclear reactions on naturally occurring isotopes. The activity of the indicator radionuclide produced during irradiation is directly proportional to the amount of the element in the sample. The analytical determination is made by comparing the induced activity in the sample with well-characterized standards activated under identical conditions of neutron flux. The activities of the samples and standards are measured using gamma-ray spectroscopy. Gamma-ray radiation emitted by a radionuclide is converted to an electrical signal by a semiconductor detector. A multichannel analyzer analyzes the electrical signal. Semiconductor detectors, such as high-purity and lithium-drifted germanium detectors, are used to exploit their high resolution. Spectra produced are analyzed by software that locates and identifies peaks, and calculates the area of each peak.

Entity_Type_Label: Sargent_Lake_core.xls
Entity_Type_Definition:
Multi-element chemical compositions lake sediment core collected from a series of 1-meter cores from a single borehole in Sargent Lake, Isle Royale. Includes field number; sample descriptions, estimated depth (in centimeters) from the top of the water-sediment interface (sample depths increase with depth down hole), and quantitative results for 31 elements. Additional elements were analyzed but are not reported as they were consistently below detection limit for 90% to 100% of samples tested. Those eliminated elements and their detection limits in parts per million are: Ag (2), Au (8), Be (1), Bi (10), Cd (2), Eu (2), Ho (4), Mo (2), Sn (5), Ta (40), U (100) and Yb (1). Ga is not included as the relative percent difference between duplicates were consistently >25%.

Entity_Type:
Entity_Type_Label: Lake_Richie.xls
Entity_Type_Definition:
Multi-element chemical compositions lake sediment core collected from a series of 1-meter cores from a single borehole in Sargent Lake, Isle Royale. Includes field number; sample descriptions, estimated depth (in centimeters) from the top of the water-sediment interface (sample depths increase with depth down hole), and quantitative results for 31 elements. Additional elements were analyzed but are not reported as they were consistently below detection limit for 90% to 100% of samples tested. Those eliminated elements and their detection limits in parts per million are: Ag (2), Au (8), Be (1), Bi (10), Cd (2), Eu (2), Ho (4), Mo (2), Sn (5), Ta (40), U (100) and Yb (1). Ga is not included as the relative percent difference between duplicates were consistently >25%.
