PURPOSE: The review and revision of the Comprehensive Conservation Plan (CCP) for the Arctic National Wildlife Refuge (Arctic NWR) in northeastern Alaska is proposed. Originally established in 1960 as Arctic National Wildlife Range, Arctic NWR encompasses 19.3 million acres of land and water, including eight million acres of designated wilderness and three wild and scenic rivers (Ivishak, Sheenjek, and Wind rivers). At least 48 species of mammals are present at Arctic NWR, including several high-profile and special-status species: polar and grizzly bears, wolf, wolverine, Dalls sheep, moose, muskox, beluga whale, and two free-roaming caribou herds. At least 42 species of fish inhabit Refuge waters and more than...

The purpose of this map is to provide a georeferenced characterization of vegetation in the early stages of Euro-American settlement. One of the research uses for the surveys nationally is for presettlement vegetation. This data can be used to analyze presettlement vegetation patterns for the purpose of determining natural community potential, productivity indexes, and patterns of natural disturbance. The area of the original plat maps were townships; use of the data at a larger scale would not be appropriate.In Illinois, the surveys began in 1804 and were largely completed by 1843. The surveyors moved across the state laying out a rectangular grid system, known as the Public Land Survey System (PLS or PLSS). They...

Fish dump toxic industrial compounds in Alaskan lakes on their return from the ocean. Pollutants are widely distributed by the atmosphere and the oceans1. Contaminants can also be transported by salmon and amplified through the food chain. Here we show that groups of migrating sockeye salmon (Oncorhynchus nerka) can act as bulk-transport vectors of persistent industrial pollutants known as polychlorinated biphenyls (PCBs), which they assimilate from the ocean and then convey over vast distances back to their natal spawning lakes. After spawning, the fish die in their thousands — delivering their toxic cargo to the lake sediment and increasing its PCB content by more than sevenfold when the density of returning salmon...

The basis for these features is U.S. Geological Survey Scientific Investigations Report 2017-5024 Flood Inundation Mapping Data for Johnson Creek near Sycamore, Oregon. The domain of the HEC-RAS hydraulic model is a 12.9-mile reach of Johnson Creek from just upstream of SE 174th Avenue in Portland, Oregon, to its confluence with the Willamette River. Some of the hydraulics used in the model were taken from Federal Emergency Management Agency, 2010, Flood Insurance Study, City of Portland, Oregon, Multnomah, Clackamas, and Washington Counties, Volume 1 of 3, November 26, 2010. The Digital Elevation Model (DEM) utilized for the project was developed from lidar data flown in 2015 and provided by the Oregon Department...

Understanding the role of permafrost in controlling groundwater flow paths and fluxes is central in studies aimed at assessing potential climate change impacts on vegetation, species habitat, biogeochemical cycling, and biodiversity. Recent field studies in interior Alaska show evidence of hydrologic changes hypothesized to result from permafrost degradation. This study assesses the hydrologic control exerted by permafrost, elucidates modes of regional groundwater flow for various spatial permafrost patterns, and evaluates potential hydrologic consequences of permafrost degradation. The Yukon Flats Basin (YFB), a large (118,340 km super(2)) subbasin within the Yukon River Basin, provides the basis for this investigation....

Dr. Richard Janda of the USGS began a channel monitoring program in Redwood Creek in northern coastal California in 1973. The USGS continued this work through 2013, when the Research Geologist, Dr. Mary Madej retired. This effort produced 40 years of channel change data in rivers that were disrupted by severe erosion following timber harvest of old-growth redwood forests, a portion of the program's data (plus 1953 data) has been preserved in this data release. Original field surveys documented bank erosion, aggradation, and degradation at 60 cross-sectional transects at annual or biannual timesteps. Three river reaches also have long-term longitudinal channel bed surveys which document the distribution and development...

MethodsStudy area: Our initial study area included the entire globe. We began with a seamless grid of cells with a resolution of 0.5 degrees (i.e., ~50 km at the equator). Next, we created polylines representing coastlines using SRTM (Shuttle Radar Topographic Mission) v4.1 global digital elevation model data at a resolution of 250 m (Reuter et al. 2007). We used these coastline polylines to identify and retain cells that intersected the coast. We excluded 192,227 cells that did not intersect the coast. To avoid cells with minimal potential coastal wetland habitat, we used the coastline data to remove an additional 1,056 coastal cells that contained less than or equal to 5% coverage of land. We also removed 176...

The Rainwater Basin wetland complex (RWB) provides critical spring migration habitat for millions of waterfowl annually. As the region was settled, the abundant wetlands were drained for agricultural purposes. The ephemeral nature of these wetlands and lack of contemporary data prompted the Rainwater Basin Joint Venture to acquire aerial photography on an annual basis. Imagery was collected during peak waterfowl migration in the spring of 2004 and annually from 2006 to 2015. These years characterize a wide range of high plains climactic variability, ranging from drought to flooding. Analyses of these data have provided new insight into the distribution, function, and habitat provided by RWB wetlands. These...

Introduction This data release is a compilation of known landslides, debris flows, lahars, and outburst floods that generated seismic signals observable on existing seismic networks. The data release includes basic information about each event such as location, volume, area, and runout distances as well as information about seismic detections and the location of seismic data, photos, maps, GIS files, and links to papers, websites, and media reports about the event. Not all record types exist for each event, and the quality of the information varies from event to event. While the SQLite3 database (lsseis.db) is the native format of this database and preserves its relational structure, for the convenience of users,...
