Dataset Title: CHANGES Project - Justification Report Chemical Rehabilitation (CJUS)
Dataset Creators: K.M. Alofs, J. Schell, K.B.S. King, A. Thomer, K. Wehrly, & H. Lopez-Fernandez

Funding: Michigan Institute For Data & AI In Society (MIDAS) Propelling Original Data Science Grant
Research Overview:
Archives at the Institute for Fisheries Research (IFR) hold records of thousands of lake surveys from the University of Michigan and Michigan Department of Natural Resources. The records contained in this dataset are jpeg images of the index card records from the IFR surveys for Justification Report Chemical Rehabilitation (CJUS). Images include the front of the card and when available, the back of a card.
Justification Report Chemical Rehabilitation cards detail initial lake survey information and recommendations for potential removal of fish populations using chemical treatments in order to stock with desired fishes. The lake survey includes the percent of each species from the total community caught, temperature and oxygen profile data, bottom substrate information, alkalinity, Secchi disk depth, and water color. A summary of the findings and recommendations for the lake are on the back of the card. These cards complement the CEVA and CTRE cards.
Methodology:
The card images were scanned in batches using high throughput duplexing document scanners. Scanned cards were organized by card type, county, and lake name. We uploaded scanned images to Zooniverse after creating a CSV file that lists each file name. Zooniverse is a web-based community science platform that we used to transcribe selected fields from the cards in our project “Angling for Data on Michigan Fishes” (www.zooniverse.org). Each card received a unique identifier (subject_id), which can be linked to the front and back of a card (1 or 2 images), and to all transcriptions from that record.
Instrument and/or Software specifications: NA
Files contained here:
The folders show divisions based on the county where the lake resides. Within each county folder are jpeg images of index cards. The csv file is a guide for each subject_id and associated image/s.
The image files are named as follows: [CountyName]_[LakeName]_[CardType]_####_##.jpg, where the first set of numbers is sequential with each new card for a specific lake/county and the final number 01 or 02 denotes the first or second image associated with the same card (i.e. front or back of a card). In some instances the file name includes an alphanumeric string (Township, Range, and Section) after the lake name.
