This collection contains the report log files produced by the R Package “AKaerial” when the QC data were created from the raw transcribed data. The QC log files document the quality control process, data standards, and what changes (if any) were made to the QC data compared to the raw data. Each log file was named following the same file naming conventions: SSSYYYY_QCLog_OOOO, where; YKD=Duck data, YKG=Goose data, YYY=Year, and OOO=observer’s first initial and last name.

R code that takes in the nest capture history data (chdata.csv), reformats it for model fitting in the Bayesian MCMC software JAGS via the R package jagsUI. Various generalized linear mixed models are fit using a Huggins two occasion capture history model structure as in Program Mark. A series of models of increasing complexity are fit and compared using DIC. Model text is written to text files for each model but is generally not used or saved. Posteriors are saved as Rworkspaces or written to text files for use in population estimation (nostpop.R). Code can be run to generate model results and R workspaces/objects to inspect parameter estimates. The primary purpose of this code is to compare various mixed model...

This multi-layer GeoPackage contains the Alaska Arctic Coastal Plain Aerial Breeding Pair Survey design transects from 2007 to present. The original transects were created as shapefiles and imported to this SQLite database. Transects were saved as individual polylines named according to the year they were created (e.g., “main.ACP_2007_Trans,” “main.ACP_2008_Trans,” “main.ACP_2009_Trans,” etc.). These aerial transects were developed systematically from randomly-selected start points and created along constant lines of latitude. The inter-transect spacing in the low, medium, high, and very-high density strata varies so that areas with higher waterfowl density are surveyed more intensively. The current four-year rotating...
The purpose of this Assessment is to understand how much upland hardwood forest and woodland habitat is available and what condition that habitat is currently in relative to habitat targets, or endpoints, defined in the ISA. To assess the ISA endpoints for upland hardwood systems, it was necessary that the most consistent, comprehensive, current and accurate data be used in summary and analysis. For the best possible assessment product we cross-checked geospatial datasets spanning variable time periods and data sources in the Ozark Highlands subgeography and remainder of the GCPO geography.

A revolution is underway in seismology that transforms fiber-optic cables into arrays of thousands of seismic sensors. Compared to the traditional monitoring networks using inertial seismometers, the fiber-optic approach can increase the spatial data density by orders of magnitude and enable data processing methodologies that require a high-fidelity wavefield. The Working Group aims to advance the USGS, along with several academic and industry partners, towards effective utilization of fiber-optic sensing techniques to understand earthquake hazards and improve monitoring and real-time warning systems. We will conduct synthesis studies that demonstrate the potential gains for various applications, including earthquake...

This dataset was last updated 05/2016. This version was updated using DSLland Version 3.1. The update to DSLland Version 3.1 from Version 3.0 is the addition of a lakes and ponds classification. This dataset depicts the ecological integrity of locations (represented by 30 m grid cells) throughout New York State based on environmental conditions existing in approximately 2010. Ecological integrity is defined as the ability of an area (e.g., local site or landscape) to sustain important ecological functions over the long term. In particular, the functions include the long-term ability to support biodiversity and the ecosystem processes necessary to sustain biodiversity. The Index of Ecological Integrity (IEI) is...

The sagebrush ecosystem spans over 175 million acres in the western United States, and is biologically, culturally, and economically significant to the country. Many disturbances including prolonged drought, pinyon-juniper encroachment, and cycles of invasive grasses and wildfire, pose significant threats to the resilience of the sagebrush biome. To conserve the sagebrush biome and promote community and economic sustainability, the Department of the Interior’s bureaus and offices are working together with many public and private partners to implement a “defend and grow the core” approach to conserve remaining intact sagebrush habitat and ecosystem functions, as well as restore other habitat types which are important...

Originally created by Brad Shults, the GitHub repository was created for markdown code used to quality control survey data and create annual survey reports beginning in 2016. The repository can be found on GitHub (‘https://github.com/bsshults/Teshekpuk-Lake-Molt’). A copy of the master branch that was last committed by user “bsshults” (Brad Shults) on 2/24/20 was downloaded by Maggie Harings on 6/29/21 and stored on the Alaska Regional Data Repository (‘GitHub_Annual_Report_Code’). General file naming structure for repository files is: ‘TMGSurvey_Master_[surveyYear]’ Files ending in the file extension ‘.Rmd’ are used to conduct some quality control and data tidying for original survey data. These files contain comments...

This multi-layer GeoPackage contains the YKD Coastal Zone Survey design transects from 1985 to present. The original transects were imported to this SQLite database structure and saved as individual polylines named according to the year they were created (e.g., “main.YK_1985_Trans,” “main.YK_1986_Trans,” “main.YK_1987_Trans,” etc.). The aerial transects were developed systematically from randomly-selected start points and created along constant lines of latitude. The inter-transect spacing in the low, medium, high, and very-high density strata varies so that areas with higher waterfowl density are surveyed more intensively. Though the overall study area never changed, the YKD Survey design was modified several times,...

This data set provides the coordinates of plot centers, the area of each plot, plot type, and search history of the plot. Plots in this data set are linked through the combination of plot number and year provided in this file. Plot search history indicates if a plot was searched for nests. Plot shape and area has varied through time. After 1985, plot were selected by stratified random sampling, and after 1998 by simple random sampling from the area defined in ‘YKD Nest Plot Study Area Boundary.’ Plot shape has also varied but after 1998 was generally 1/4 by 1/2 mile.

In 2019 a pilot study was conducted to determine the feasibility of using distance sampling to estimate density and population size of goose and eider nests on the Yukon-Kuskokwim Delta (YKD). Distance sampling (Buckland et al. 2001) is a common and well-understood method to estimate wildlife population size or density, especially for sparse and hard-to-detect populations. A main advantage of distance sampling is that it accounts for imperfect detection and gives precise estimates for a given level of effort relative to other methods. The objectives for the pilot project in 2019 was to (1) determine if distance sampling is feasible on the YKD, (2) determine what aspects of the field protocol need to be changed or...
Open Pine Woodland and Savanna was assessed by evaluating endpoint variable values from spatial data layers. Spatial data inputs included a set of selected ecological system and land use classes from the National GAP Land Cover Data Product and estimated percent canopy cover from NLCD 2011. Midstory conditions, average tree diameter, and basal area endpoint thresholds were derived from US Forest Service data products that use remote sensing data to impute Forest Inventory and Analysis (FIA) data across the landscape. The Condition Index is a pixel-by-pixel analysis with a score range of 0 – 21 at a spatial resolution of 250 meters. The process first assesses whether the pixel is in a pine or mixed-pine forested...

We developed a composite land cover approach for use in the GCPO LCC ecological assessment of upland hardwood woodlands and forests. These datasets reflect the upland hardwood “mask” that represents the composite of 3 or 4 datasets, from which the remaining landscape endpoints defined in the LCC Integrated Science Agenda will be evaluated. The mask indicates where on the landscape we estimate upland hardwood woodlands and forests to be found in any condition. We first resampled 30 m 2011 GAP ecological systems land cover and Florida Cooperative Land Cover version 3.1, as well as 10 m Texas and Oklahoma Ecological Systems Mapping land cover data to 250 m using a nearest neighbor algorithm. The assessment was conducted...
