Predicted Arctic Beaded Stream Locations

This dataset contains predicted beaded stream locations from an analysis of high-resolution satellite imagery, using both decision tree regression and object detection from You-Only-Look-Once algorithm (v5). Beaded streams are low-order streams found in high latitude regions near permafrost that form unique 'beads-on-a-string' morphology in a pool-chute structure and represent an important habitat for Arctic grayling fish.

Included here are estimated locations of catchments that contain beaded streams from a decision tree classification (MERIT_possible_beads.zip) based on a MERITHydro-Vector dataset (https://doi.org/10.6084/m9.figshare.13377329), circumpolar permafrost dataset (https://doi.org/10.7265/skbg-kf16), and a previous study on Arctic beaded streams (Arp et al., 2015; https://doi.org/10.5194/bgd-11-11391-2014).

Also included is a list of catchments that were manually classified or classified by the Arp et al. (2015) paper as beaded (training_catchments.csv), and predicted boxes from the object detection analysis (YOLOv5_prediction_boxes.zip). 

Finally, code to reproduce some of these results are located in Beaded_Streams-1.0.0.zip, or can be found on github: Release Predicted Arctic Beaded Stream Locations · merrittharlan/Beaded_Streams (github.com).
