  1. Title: Folds: Hueneme Canyon and Vicinity, California, 2012

    Contributors:

    Summary: This line shapefile represents geologic folds for Hueneme Canyon and the surrounding vicinity in California. The offshore map area is characterized by two major physiographic features: (1) the nearshore continental shelf and upper slope; and (2) Hueneme Canyon and parts of three smaller, unnamed submarine canyons incised into the shelf southeast of Hueneme Canyon. The nearshore, shelf, and slope are underlain by recent sediments and characterized by active sediment transport. Shelf and slope morphology and evolution result from drainage incision into deltaic sediments of the Oxnard plain during sea-level lowstand and subsequent sedimentation as sea level rose about 125 to 130 m over the last ~18,000 to 20,000 years (Lambeck and Chappell, 2001). This map area occurs in the southern part of the Western Transverse Ranges province, north of the California Continental Borderland (Fisher and others, 2009). Shelf deposits are deformed in the northernmost part of the map area by the west-trending Montalvo Fault and Anticline (Fisher and others, 2005). The Montalvo structures are part of a band of active deformation that includes the west-trending Oak Ridge Fault (Fisher and others, 2005), which extends into the offshore just a few km north of this map area. The Oak Ridge-Montalvo Fault Zone forms the southern boundary of the Ventura Basin and is considered an earthquake hazard because it extends along strike for about 130 km and appears to be the westward continuation of the fault system responsible for the 1994 M 6.7 Northridge earthquake. Only data for offshore map units are released digitally in this publication. For onshore geology (sheet 10) see Clahan (2003). The map was published in Scientific Investigations Map 3225. This layer is part of the USGS Data Series 781. In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP) to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats and geology within the 3-nautical-mile limit of California's State Waters. CSMP has divided coastal California into 110 map blocks, each to be published individually as United States Geological Survey Open-File Reports (OFRs) or Scientific Investigations Maps (SIMs) at a scale of 1:24,000. Maps display seafloor morphology and character, identify potential marine benthic habitats and illustrate both the seafloor geology and shallow (to about 100 m) subsurface geology. Data layers for bathymetry, bathymetric contours, acoustic backscatter, seafloor character, potential benthic habitat and offshore geology were created for each map block, as well as regional-scale data layers for sediment thickness, depth to transition, transgressive contours, isopachs, predicted distributions of benthic macro-invertebrates and visual observations of benthic habitat from video cruises over the entire state.

  2. Title: Submarine Landslide Scarps: Hueneme Canyon and Vicinity, California, 2012

    Contributors:

    Summary: This line shapefile represents submarine landslide scarps of the geologic/geomorphic map of the Hueneme Canyon and surrounding vicinity in California. The offshore map area is characterized by two major physiographic features: (1) the nearshore continental shelf and upper slope; and (2) Hueneme Canyon and parts of three smaller, unnamed submarine canyons incised into the shelf southeast of Hueneme Canyon. The nearshore, shelf and slope are underlain by recent sediments and characterized by active sediment transport. Shelf and slope morphology and evolution result from drainage incision into deltaic sediments of the Oxnard plain during sea-level lowstand and subsequent sedimentation as sea level rose about 125 to 130 m over the last ~18,000 to 20,000 years (Lambeck and Chappell, 2001). Hueneme Canyon extends about 15 km offshore from its nearshore canyon head. The canyon is relatively deep (~150 m at the California's State Waters 3-nm limit) and steep (canyon walls as steep as 25 degrees to 30 degrees). The heads of the three smaller unnamed canyons southeast of Hueneme Canyon are not connected to the nearshore. During the last sea-level lowstand, these canyons were connected to coastal watersheds that fed coarse-grained sediment directly to Hueneme submarine fan (Normark and others, 2009). In the ensuing transgression, Hueneme Canyon maintained its connection with the shoreline as it eroded headward, while these smaller canyons were isolated and abandoned. "Outer" canyon walls in both Hueneme Canyon and the smaller unnamed canyons extend upward to the shelf edge and vary from smooth to deeply incised. "Inner" canyon walls occupy an intermediate position between the shelf edge and canyon floor. Both outer and inner canyon walls formed primarily by landsliding. Three different landslide units are mapped in Hueneme Canyon based on their morphology and relative age inferred from crosscutting and (or) draping relationships. Landslide units are undifferentiated where these morphology and relative age indicators are not distinct. The landslide units commonly include both steep erosional scarps and paired hummocky landslide deposits, and it is this genetic pairing (scarps with landslides) that distinguishes the scarps within landslide units from the scarps within the canyon-wall units. Lower-relief, sediment-draped, deep-seated slumps are mapped as separate landslide units. The map was published in Scientific Investigations Map 3225. This layer is part of the USGS Data Series 781.

  3. Title: Paleoshorelines: Hueneme Canyon and Vicinity, California, 2012

    Contributors:

    Summary: This line shapefile represents paleoshorelines for the geologic and geomorphic map (see sheet 10, SIM 3225) of the Hueneme Canyon and surrounding vicinity in California. The offshore map area is characterized by two major physiographic features: (1) the nearshore continental shelf and upper slope; and (2) Hueneme Canyon and parts of three smaller, unnamed submarine canyons incised into the shelf southeast of Hueneme Canyon. The nearshore, shelf, and slope are underlain by recent sediments and characterized by active sediment transport. Shelf and slope morphology and evolution result from drainage incision into deltaic sediments of the Oxnard plain during sea-level lowstand, and subsequent sedimentation as sea level rose about 125 to 130 m over the last ~18,000 to 20,000 years (Lambeck and Chappell, 2001). Sea-level rise (controlled by both eustasy and tectonic land-level change) was apparently not steady during this period, leading to development of shorelines during periods of relative sea-level stability. These paleoshorelines, characterized by shoreline angles and adjacent submerged wave-cut platforms and risers (Kern, 1977), are commonly buried by shelf sediment. However, their original morphology is at least partly preserved on the outer shelf and upper slope on the east flank of Hueneme Canyon. The geologic map includes four wave-cut platforms and risers separated by shoreline angles at depths of approximately 65 m, 75 to 85 m, 95 to 100 m, and 120 to 125 m. The map was published in Scientific Investigations Map 3225. This layer is part of the USGS Data Series 781.

  4. Title: Faults: Hueneme Canyon and Vicinity, California, 2012

    Contributors:

    Summary: This line shapefile represents fault lines for Hueneme Canyon and the surrounding vicinity in California. The offshore map area is characterized by two major physiographic features: (1) the nearshore continental shelf and upper slope; and (2) Hueneme Canyon and parts of three smaller, unnamed submarine canyons incised into the shelf southeast of Hueneme Canyon.

  5. Title: Geology: Hueneme Canyon and Vicinity, California, 2012

    Contributors:

    Summary: This polygon shapefile represents geologic features of Hueneme Canyon and the surrounding vicinity in California. The offshore map area is characterized by two major physiographic features: (1) the nearshore continental shelf and upper slope; and (2) Hueneme Canyon and parts of three smaller, unnamed submarine canyons incised into the shelf southeast of Hueneme Canyon. The nearshore, shelf, and slope are underlain by recent sediments and characterized by active sediment transport. Nearshore and shelf deposits are predominantly sand (Qms), modified by human activities (af) in parts of the nearshore, and locally exhibiting scour depressions (Qmss) and hummocky relief (Qmsh). Outer shelf and slope deposits consist of mixed sand and mud (Qmsl), locally containing grouped to solitary pockmarks (Qmp) and incised by narrow rills (Qmr). Shelf and slope morphology and evolution result from drainage incision into deltaic sediments of the Oxnard plain during sea-level lowstand, and subsequent sedimentation as sea level rose about 125 to 130 m over the last ~18,000 to 20,000 years (Lambeck and Chappell, 2001). Sea-level rise (controlled by both eustasy and tectonic land-level change) was apparently not steady during this period, leading to development of shorelines during periods of relative sea-level stability. These paleo-shorelines, characterized by shoreline angles and adjacent submerged wave-cut platforms and risers (Kern, 1977), are commonly buried by shelf sediment. However, their original morphology is at least partly preserved on the outer shelf and upper slope on the east flank of Hueneme Canyon. Geologic map units include four wave-cut platforms (Qwp1, Qwp2, Qwp3, and Qwp4) and risers (Qwpr1, Qwpr2, Qwpr3, and Qwpr4), separated by shoreline angles at depths of approximately 65 m, 75 to 85 m, 95 to 100 m, and 120 to 125 m. Hueneme Canyon extends about 15 km offshore from its nearshore canyon head. The canyon is relatively deep (~150 m at the California's State Waters 3-nm limit) and steep (canyon walls as steep as 25 degrees to 30 degrees). The heads of the three smaller unnamed canyons southeast of Hueneme Canyon are not connected to the nearshore. During the last sea-level lowstand, these canyons were connected to coastal watersheds that fed coarse-grained sediment directly to Hueneme submarine fan (Normark and others, 2009). In the ensuing transgression, Hueneme Canyon maintained its connection with the shoreline as it eroded headward, while these smaller canyons were isolated and abandoned."Outer" canyon walls in both Hueneme Canyon and the smaller unnamed canyons extend upward to the shelf edge and vary from smooth (sediment draped, Qcwo1) to deeply incised (Qcwo2). "Inner" canyon walls (Qcwi) occupy an intermediate position between the shelf edge and canyon floor. Both outer and inner canyon walls formed primarily by landsliding. Three different landslide units are mapped in Hueneme Canyon on the basis of their morphology and relative age, inferred from crosscutting and (or) draping relations - Qls1 (oldest), Qls2, and Qls3 (youngest). Landslide units are undifferentiated (Qls) where morphology and relative-age indicators are not distinct. The landslide units commonly include both steep erosional scarps and paired hummocky landslide deposits, and it is this genetic pairing (scarps with landslides) that distinguishes the scarps within landslide units from the scarps within the canyon-wall units. Lower relief, sediment-draped, deep-seated slumps are mapped as a separate landslide unit (Qlss). Canyon channel head units (Qcch) are delineated on the basis of their incision into the nearshore (Hueneme Canyon) or outer shelf (three smaller canyons southeast of Hueneme Canyon), relatively steep gradients, and V-shaped profiles. These channel heads merge into lower gradient and more flat-bottomed canyon floor channel units (Qccf). The Hueneme Canyon channel floor is a zone of active sediment transport characterized by large, asymmetric bedforms, bounded by steep channel walls (Qccw). Narrow, elongate channel-flanking bars (Qccb) are elevated above and morphologically distinct from the channel floors and broken out as separate units. In addition to landslide and canyon-channel deposits, three additional canyon-fill units are recognized. Axial channel fill (Qcfa) units form elevated surfaces 20 to 50 m above the floors of Hueneme Canyon and smaller submarine canyons, dip gently downcanyon, and consist of well-stratified sediment (sand, mud, gravel?), distinguished on the basis of seismic-reflection data (high frequency, moderate amplitude, parallel reflections). Lateral canyon fill unit (Qcfl), located on the east flank of Hueneme Canyon near its head, consists of west-dipping stratified sediment (distinguished on the basis of seismic-reflection facies) that probably formed as distributed fluvial input into the canyon during the middle to late Holocene. Submarine canyon tributary-channel-fill units (Qcft) are inferred to have formed as direct middle to late Holocene fluvial entrants into canyons, subsequently partly filled by nearshore and shelf sediment during sea level rise. There is one occurrence of undifferentiated bedrock (Tbu) in the map area, on the slope at water depths of about 300 to 350 m, on the west flank of Hueneme Canyon channel. This unit is recognized on the basis of high backscatter and massive character on seismic-reflection data previously mapped this bedrock as the Miocene Monterey Formation. This map area occurs in the southern part of the Western Transverse Ranges province, north of the California Continental Borderland (Fisher and others, 2009). Shelf deposits are deformed in the northernmost part of the map area by the west-trending Montalvo Fault and Anticline (Fisher and others, 2005). The Montalvo structures are part of a band of active deformation that includes the west-trending Oak Ridge Fault (Fisher and others, 2005), which extends into the offshore just a few km north of this map area. The Oak Ridge-Montalvo Fault Zone forms the southern boundary of the Ventura Basin and is considered an earthquake hazard because it extends along strike for about 130 km and appears to be the westward continuation of the fault system responsible for the 1994 M 6.7 Northridge earthquake.

  8. Title: Racial Covenants [Hennepin County, Minnesota] (1910-1955)

    Contributors:

    Summary: This data was compiled by the Mapping Prejudice Project and shows the location of racial covenants recorded in Hennepin County between 1910 and 1955. Racial covenants were legal clauses embedded in property records that restricted ownership and occupancy of land parcels based on race. These covenants dramatically reshaped the demographic landscape of Hennepin County in the first half of the twentieth century. In 1948, the United States Supreme Court ruled racial covenants to be legally unenforceable in the Shelly v. Kraemer decision. Racial covenants continued to be inserted into property records, however, prompting the Minnesota state legislature to outlaw the recording of new racial covenants in 1953. The same legislative body made covenants illegal in 1962. The practice was formally ended nationally with the passage of the Fair Housing Act in 1968.

  18. Title: Cover Types of the UMN Cloquet Forestry Center, 2021 {Cloquet, Minnesota}

    Contributors:

    Summary: Cover Types of the UMN Cloquet Forestry Center, 2021 is a polygon representation of forest stands and other vegetation types across the 3400-acre research forest. Polygon attributes represent the current status of forest inventory records for the CFC at the end of 2021 based on episodic updates to an original 2005 cover type mapping product. The University of Minnesota (UMN) Cloquet Forestry Center is a field research and instructional station associated with the College of Food, Agricultural, and Natural Resources Sciences (CFANS). The original dataset (shapefile) inventorying forest cover types at the University of Minnesota Cloquet Forestry Center was an outcome of a 2005 Covertype Mapping Project produced by Brian C. Loeffelholz and Guthrie Zimmerman on behalf of the UMN Department of Forest Resources (https://hdl.handle.net/11299/120191). The data provided here represents episodic updates to the 2005 covertype shapefile since that time. Forest stand boundaries, stand attributes, and attribute fields have been modified by Cloquet Forestry Center staff through 2021 to reflect spatial and temporal changes to cover types over time and from various management actions, predominately timber harvests.

  19. Title: Climate-biome envelope model for the Western Great Lakes Region

    Contributors:

    Summary: Research Highlights: We modeled climate-biome envelopes at high resolution in the Western Great Lakes Region for recent and future time-periods. The projected biome shifts, in conjunction with heterogeneous distribution of protected land, may create both great challenges for conservation of particular ecosystems and novel conservation opportunities. Background and Objectives: Climate change this century will affect the distribution and relative abundance of ecological communities against a mostly static background of protected land. We developed a climate-biome envelope model using a priori climate-vegetation relationships for the Western Great Lakes Region (Minnesota, Wisconsin and Michigan USA and adjacent Ontario, Canada) to predict potential biomes and ecotones—boreal forest, mixed forest, temperate forest, prairie–forest border, and prairie—for a recent climate normal period (1979–2013) and future conditions (2061–2080). Materials and Methods: We analyzed six scenarios, two representative concentration pathways (RCP)—4.5 and 8.5, and three global climate models to represent cool, average, and warm scenarios to predict climate-biome envelopes for 2061–2080. To assess implications of the changes for conservation, we analyzed the amount of land with climate suited for each of the biomes and ecotones both region-wide and within protected areas, under current and future conditions. Results: Recent biome boundaries were accurately represented by the climate-biome envelope model. The modeled future conditions show at least a 96% loss in areas suitable for the boreal and mixed forest from the region, but likely gains in areas suitable for temperate forest, prairie–forest border, and prairie. The analysis also showed that protected areas in the region will most likely lose most or all of the area, 18,692 km2, currently climatically suitable for boreal forest. This would represent an enormous conservation loss. However, conversely, the area climatically suitable for prairie and prairie–forest border within protected areas would increase up to 12.5 times the currently suitable 1775 km2. Conclusions: These results suggest that retaining boreal forest in potential refugia where it currently exists and facilitating transition of some forests to prairie, oak savanna, and temperate forest should both be conservation priorities in the northern part of the region. Data included here are the R code used to process the publicly available CHELSA data (see publications for citation) into the biome-climate envelope product (as .R files and .txt files) and the climate-biome envelope product itself (as .tif files).

  20. Title: Springer Lab UAV Maize Phenotyping Project at UMN Saint Paul: 2018 and 2019 {Minnesota}

    Contributors:

    Summary: This dataset provides a valuable resource for evaluating the utility of unmanned aerial vehicles to collect phenotypic data in agricultural fields. Many flights throughout the growing season of a maize experiment were conducted and this dataset includes digital elevation models generated from images within these flights, the plot boundary shapefiles for plot identification, plant height values extracted following Tirado et al., 2019 procedure, hand measurement height values conducted following flights, and yield data for each plot. This maize experiment consisted of twelve hybrids planted at three different planting densities (low, medium and high) and two planting dates (early and late) across two years and therefore provides a valuable resource for evaluating how temporal data collected from UAVs can aid in assessing plant productivity. It can also be utilized to develop and test different protocols for plant height extraction from DEMs at different growth stages as the hand measurements can be used to test the accuracy. Files include digital elevation models for all flights of our maize field in the summer of 2018 and 2019, the plot boundary shapefiles, information on each plot including planting date and density and stand counts, yield data for all plots, and weather station data for both summers. More detailed info can be found in the readme file.
