Southeast Alaska Seabird and Sea Otter Survey Bird Densities Code This is the R code that was implemented to tidy the original 1994 MBM-AK SEAK bird density dataset (“1994_SEAK_BirdDensities.csv”), producing the final dataset “1994_SEAK_BirdDensities_tidy.csv”. In doing so, the original dataset was reshaped so that all species and bird densities were located in two distinct columns.

Original Southeast Alaska Marine Bird and Sea Otter Survey Paradox Files This is a collection of the original Paradox files produced during the 1994 MBM-AK SEAK survey. Paradox is an outdated relational database program that is now obsolete. Therefore, most of the individual files and sidecar files contained within this collection cannot be further described because we are not able to view them at this time. Because Borland (owner of Paradox) never defined file extensions for Paradox, the following is a list of file extensions found within this collection and for those with commonly-recognized definitions, those are included as well: .DB (Paradox table), .SSL(script source), .RSL (report source), .COL, .N00, .N01, TVF (table view settings for dBASE table), .FAM (listing of related files),...

Southeast Alaska Marine Bird and Otter Survey Transect Midpoints GeoJSON This is the GeoJSON file that contains the 1994 MBM-AK SEAK transect midpoints. Its projection is WGS84 (EPSG: 4326) and it was generated from the original midpoints shapefile (‘Transect_Midpoints’) using R code. With the exception of reprojecting this file to WGS84 (ESPG: 4326), no other modifications were made to this spatial extent. It is critical to note that the location of transect midpoints found in this GeoJSON file need to be ground-truthed, as the projection used when producing the transect midpoint shapefile may have varied from the projection used when producing the original transect midpoint data during the 1994 SEAK survey.

Southeast Alaska Marine Bird and Sea Otter Survey During June and July 1994, the U. S. Fish and Wildlife Service (USFWS), Nongame Migratory Bird Management (MBM-AK) and the Southeast Alaska Ecological Services Field Office conducted a shipboard survey of Southeast Alaska (SEAK) to estimate population abundance and distribution of marine birds and sea otters. This baseline survey was conducted to monitor changes in bird and otter abundance over time. Specific objectives were to: (1) estimate summer abundance and density of marine birds and sea otters; (2) describe marine bird and sea otter distribution; (3) determine the relative abundance and densities of marine bird species groups; (4) document locations and abundance of marine bird nesting colonies encountered;...

Southeast Alaska Seabird and Sea Otter Survey Transect Midpoints Shapefile This is the shapefile folder that contains the shapefile (.shp) and corresponding sidecar files (.dbf, .prj, .sbn, .sbx, .xml, .shx) that produce the spatial extent of 1994 MBM-AK SEAK transect midpoints. Because all original transect data for this survey were lost, Elizabeth Labunski generated this in 2004 from the “Transects_Surveyed” shapefile she created using old Atlas GIS files and a hard copy map of transects pertaining to the 1994 SEAK survey. It is critical to note that the location of transect midpoints found in this transect midpoints shapefile need to be ground-truthed, as the projection used when producing the transect shapefile (“Transects_Surveyed”) may have varied from the actual projection used...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
