#OVERVIEW 
#
#This dataset contains all files to produce analyses presented in the associated manuscript, with the exception of the tourism data, which is available upon request from IAATO (https://iaato.org/).
#
#The code associated with these data can be found here: https://github.com/Penguin-Watch/penguin_watch_model
#
#All files are located within 'data_files.zip'. 'PW_data_2019-10-07.csv' and the files within 'precip_data/' were generated as a part of this research. The .shp files contained within 'peninsula/', 'Sub-antarctic_coastline_low_res_polygon/', and 'ssmu-shapefile-WGS84/' were obtained from other sources (links below) and were used in the analyses. 'AggregatedKrillCatch.csv' was obtained as part of the CCAMLR 2019 Statistical Bulletin Volume 31 (link below).

#############################
*PW_data_2019-10-07.csv
-Penguin chick classifications (i.e., number of chicks observed for each nest) derived from time-lapse camera data. Images were manually annotated by domain experts and checked for quality. See associated publication for methodological details. These data were used as input for the capture-recapture model. Entries were filled with NA values to create a complete time series.

FIELDS
    -imagename - image name from the camera
    -site - site same of the penguin colony
    -camera_letter - camera identification letter for that site (if there were multiple cameras at a site)
    -view_letter - the view identification letter (if memory cards were swapped mid-season)
    -season_year - season-year for this row of data (where the 2015/2016 season is noted as 2016)
    -imageid - image identification number
    -col_lat - colony latitude
    -col_lon - colony longitude
    -moon - moon cycle
    -tempf - temperature (not available for most images)
    -datetime - timestamp from camera
    -year - calendar year
    -month - calendar month
    -day - calendar day
    -time - time of day
    -nestX - the number of observed chicks (0/1/2) for that row, where X is the nest number for that site/year (where NA indicates no data collected)
    -nest_X_x.coord - the x coordinate of nest X in the camera image (where 0,0 is the top-left of the image)
    -nest_X_y.coord - the y coordinate of nest X in the camera image (where 0,0 is the top-left of the image) 
    

#############################
*precip_data/
-Precipitation classifications derived from camera trap data. Precipitation was scored by two individuals independently as rain (R) or snow (S) on a scale from 1 to 3 (small to large). Each file represents scores from a different site/year. See associated publication for methodological details.

FIELDS
    -imagename - image name from the camera
    -score - precipitation score
    -datetime - time stamp from camera
