Airborne magnetic survey, Iron Mountain-Chatham region, central Upper Peninsula, Michigan, 2018

This publication provides digital flight line data for a high-resolution magnetic survey over an area of the central Upper Peninsula of Michigan. The survey area lies approximately between the towns of Iron Mountain and Chatham. Data for this survey were collected by EON Geosciences under contract with the USGS using a fixed wing aircraft with a magnetometer mounted in the tail stinger. The survey operated out of the Sawyer International Airport near Marquette, Michigan, from June of 2018 to September of 2018. A total of 38,474 line km of data were collected. Data were collected along north-south flight lines spaced 150 meters apart with east-west tie lines flown every 1,500 meters. The nominal terrain clearance was 80 meters, although greater terrain clearances were required in several areas due to safety concerns. Files that are available in this publication include flight line data for the magnetic survey and a report describing the survey parameters, field operations, quality control and data reduction procedures. A zip file is provided that contains the contractor's deliverable products that includes Geosoft databases and grids for the magnetic survey and the report describing the survey and data reduction. Data have been redacted over two small areas (less than 1 km2 combined) near Sawyer International Airport that include multiple tracts of Native American lands.

Aerial imagery of selected new culvert installation sites in the East Gulf Coastal Plain of Alabama

The Alabama Department of Transportation (ALDOT) and the U.S. Geological Survey (USGS) studied several sites in the northern East Gulf Coastal Plain of Alabama to investigate effects of newly installed box culverts on the natural conditions of the streams they are traversing (Pugh and Gill, 2021). Data collection for the study spanned approximately 10 years and included before-, during-, and after-construction phases of box culvert installations at selected stream sites. The objectives of the project were to (1) assess the degree and extent of changes in geomorphic conditions, suspended-sediment concentrations, turbidity, and benthic macroinvertebrate populations at selected small streams following box culvert installation and (2) identify any substantial relationships between observed changes in geomorphology and benthic macroinvertebrate populations. 
Aerial imagery for each study site, taken before, during and after culvert construction, was downloaded from Google Earth (https://earth.google.com/web/) and are presented as separate Portable Document Format (PDF) files labeled by site name and imagery date. Aerial imagery was examined to see if any natural or anthropogenic changes occurred in the areas surrounding the study sites. For example, examination of the High Log Creek imagery from 2013 and 2015 shows the forested area northwest of the study site was clear cut and the start of culvert construction occurred sometime between when the two images were taken.

Determination of the effect of temperature (Q10) on denitrification rates in sediments collected from a groundwater discharge site in Ashumet Pond on Cape Cod, MA

This data release presents results from a laboratory study designed to measure the effect of temperature on denitrification rates in sediments collected from 5- to 30-cm depth below the lake bottom, at a location where groundwater discharges to the lake. Sediment cores were collected June 25, 2014 from the West site (Fishermans Cove) in Ashumet Pond, Cape Cod, MA then shipped to Boulder, CO for laboratory experiments. Groundwater used for these experiments was collected from a well just upgradient of the sediment collection site. Denitrification rates were determined on sediment plus groundwater slurries by the acetylene block method (Yoshinari and Knowles, 1976). Nitrous oxide concentrations were measured several times over the course of approximately a 7-hour period in serum bottles containing 30 g sieved sediment (&lt;2mm) combined with 30 mL filtered groundwater at 3 different incubation temperatures (4, 15, 24 degrees Celsius). Denitrification rates were calculated based on the accumulation of nitrous oxide over time in the serum bottles. The temperature coefficient, Q10, for the sediment at Ashumet Pond was calculated using these denitrification rates and was determined to be 4.9, meaning that the rate of denitrification increased by a factor of 4.9 for every 10 degrees of temperature increase.

Initial Observations of Landslides triggered by the 2018 Anchorage, Alaska earthquake

This data release provides the locations of 43 landslides that occurred during the 2018 Anchorage, Alaska earthquake mapped from high-resolution lidar (1-m). Lidar data can be accessed via the Alaska Division of Geological and Geophysical Surveys elevation portal (https://elevation.alaska.gov). Each landslide is represented as a point corresponding to the approximate location of the mid-point of the landslide head scarp. Wherever possible, the outline of (39) landslides are also provided as polygons. Areal coverage of this data release is constrained to the availability of the 1-m resolution lidar. Within this area, this data builds upon Grant et al. (2020) by more accurately locating those observed landslide features and mapping their extent where possible.

Mesocarnivore Survey of Lava Beds National Monument, Klamath Network, 2018 (ver. 2.0, April 2022)

Remote camera stations were set up in Lava Beds National Monument and Modoc National Forest from January to May 2018 to document occurrence of mesocarnivores and other wildlife. Thirty-three cameras were set up at 12 primary sampling units (clusters of one to four cameras) throughout the park. Potentially suitable habitat occurred in small patches in Lava Beds National Monument with cameras were placed in groups of one, two or three. To allow for more primary sampling units of four cameras, some cameras were installed in neighboring portions of Modoc National Forest. Cameras located in Modoc National Forest are considered part of the Lava Beds National Monument survey for the purposes of this study.
The dataset contains all species observed within the study time-frame, the date and time of observation and the number of individuals detected as well as identification for individual locations, cameras and images. None of the three target species of conservation concern ((Pacific fisher (Pekania pennanti), Pacific marten (Martes caurina), Sierra Nevada red fox (Vulpes vulpes necator)) were seen, though Gray fox (Urocyon cinereoargenteus) were detected.

Mouse predation on Laysan albatross

Invasive rodents on islands have adverse impacts on native birds in island ecosystems, and rats are the most common culprits.  Recently, house mice (Mus musculus) in the South Atlantic were found preying on three species of albatross chicks.  Here, we show that house mice can also prey on nesting adult Laysan albatross (Phoebastrea immutabilis) on Midway Atoll National Wildlife Refuge (USA).  In contrast to mouse attacks on albatross in the South Atlantic where mice targeted the rump and crown of chicks, on Midway, mice targeted nesting adults mainly on the back.  For both regions, the outcome was similar with reduced nesting success.  In the case of Midway, reduced nesting success was due to nest abandonment or mortality of one or both parents due to secondary bacterial infections.  Mortality of adult albatross has the potential to have a more potent demographic impact due to their much higher natural survivorship once they reach adulthood.    We discuss possible reasons why mice preyed on live albatross.  Pursuant to these findings, efforts are currently under way to eradicate mice on Midway Atoll.

Chesapeake Bay River Input Monitoring Network 1985-2019: WRTDS output data

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring Network (RIM) stations for the period 1985 through 2019. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the RIM watersheds.

Chesapeake Bay River Input Monitoring Network 1985-2019: Short- and long-term trends

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring Network (RIM) stations for the period 1985 through 2019. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on Time, Discharge, and Season).  The load results represent the total mass of nitrogen, phosphorus, and suspended sediment that was exported from each of the RIM watersheds.  To determine the trend in loads, the annual load results are flow normalized to integrate out the year-to-year variability in river discharge.  The trend in load is derived from the flow-normalized load timeseries and represents the change in load resulting from changes in sources, delays associated with storage or transport of historical inputs, and (or) implemented management actions.

Chesapeake Bay River Input Monitoring Network 1985-2019: Average annual yields

Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring Network (RIM) stations for the period 1985 through 2019. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach called WRTDS (Weighted Regression on Time, Discharge, and Season).  Yields (represents the mass of constituent transported from a unit area of a given watershed) are used to compare the export loads from one basin to another.  Yield results are obtained by dividing the annual load (pounds) of a given constituent by the respective watershed area (acres) from which the constituent was transported.  Yield results presented represent the average annual per-acre loads of nitrogen, phosphorus, and suspended sediment exported from each of the Chesapeake Bay River Input Monitoring stations for two possible time periods:  2010-2019 (10 year average yield) and 2015-2019 (5 year average yield).

Data for generating statistical maps of soil lithium concentrations in the conterminous United States

The product data are six statistics that were estimated for the chemical concentration of lithium in the soil C horizon of the conterminous United States. The estimates are made at 9998 locations that are uniformly distributed across the conterminous United States. The six statistics are the mean for the isometric log-ratio transform of the concentrations, the equivalent mean for the concentrations, the standard deviation for the isometric log-ratio transform of the concentrations, the probability of exceeding a concentration of 55 milligrams per kilogram, the 0.95 quantile for the isometric log-ratio transform of the concentrations, and the equivalent 0.95 quantile for the concentrations. Each statistic may be used to generate a statistical map that shows an attribute of the distribution of lithium concentration.
