This is a comma delimited text file of the bird observations for the Arctic Coastal Plain survey. These observations have undergone an extensive quality control process that is ongoing and corrected several errors in the source data. Point observation of birds are given in coordinate reference system EPSG:4326 and are accurate only to +/- 500m. The field "Year" gives the calendar year that the survey was flown, "Stratum" gives the transect density strata name, "NavTransect" gives the transect identifier used for navigation by the pilot (this is not necessarily the same as the design transect), and "Obs_Type" is the social group (single, pair, etc.) of the bird observation, "Num" is the number of observation of...

This project aims to estimate spatial and temporal trends of waterfowl and waterbirds on the Arctic Coastal Plain (ACP) of Alaska from 2007 to present. The main approach is motivated by Amundson et al. (2019) using space-time generalized additive models (GAMs, Wood 2017) but with some improvements to handle observer effects and to associate sampling effort to specific spatial locations along a sampled transect similar to Miller et al. (2013). As part of this effort, a major data quality control process was begun in March 2022 that led to the correction of many data errors and re-formatting of the original 2007 to 2023 data to make it more accessible and usable to outside partners (original raw data available here)....

This is an SQLite GeoPackage simple feature linestring vector database of the Arctic Coastal Plain survey flow tracks in coordinate reference system EPSG:4326. There is one layer for each year 2007 to 2023. The field”Year” gives the calendar year that the transects were flown, “Stratum” gives the strata name, “NavTransect” gives the transect identifier used for navigation by the pilot (this is not necessarily the same as the design transect), and the “geom” field gives the simple feature Well Known Text geometry data of the approximate flight path recreated from bird observations. See the GitHub site https://github.com/USFWS/ACP-Mapping for more information. This product was produced from the file ACPmapping.R and...

This is an SQLite GeoPackage simple feature vector database of spectacled eider relative densities predicted from a generalized additive model across the Arctic Coastal Plain. These density are “relative” because year- or observer-specific detection is not incorporated. However, the estimation model include observer as a random effect and predictions are made after removing the effect of observer (i.e., at the average observer). Each year is a separate layer named by year. Predictions are gridded into cells 750m per side but are trimmed to the ACP survey area, so some cells are smaller. For each year, the variable ‘fit’ gives the expected density, ‘se.fit’ gives the standard error of the fit, ‘Sample.Label’ is an...

This is an SQLite GeoPackage simple feature multilinestring vector database of the Arctic Coastal Plain survey transects in coordinate reference system EPSG:4326. There is one layer for each year 2007 to 2023, although in general the there is a four panel rotation that varies each year. All years are provided because implementation of the panel design varied through time. The field”Year” given the calendar year that the transects were implemented, “Stratum” gives the strata name, “Transect” gives the transect identifier, and the “geom” field gives the simple feature Well Known Text geometry data. Note that these transect are the idealized design and are not an exact record of the true flight path or survey effort....

The code repository for the quality controll processing, data creation, modelling, and mapping or trend estimation is at https://github.com/USFWS/ACP-Mapping. The full history of the quality control process and issues is documented in R code file in this repository. Please report any addition errors to https://github.com/USFWS/ACP-Mapping/issues and follow update of this repositiry to keep track of new errors and updates to data sets, maps, or trend estimates.
