Entity_Type_Definition:
Data from diver sonde deployments in Cenote Crustacea and the larger Ox Bel Ha cave network (locations: Cenote Jailhouse, Cenote Odyssey, Cenote Naach Wennen Ha). The profiles were conducted along vertical descents in the water column of the caves using a EXO1 multi-parameter datasonde (Dec 2013) and a YSI XLM-600 datasonde (Aug 2014 and Jan 2015). There are a total of 6026 data records in the dataset.

Entity_and_Attribute_Overview:
The dataset contains one Excel file with 10 tabs (sonde_2013-2015.xlsx), and 10 CSV files each corresponding to the similarly named tab in the spreadsheet (see list below). The first row (header line) of the CSV file contains the column labels (and is the same information as these attributes). The first row of the Excel spreadsheet contains a header line that includes a short description of the project and the years the data were obtained, the second row indicates the logger utilized, the third row is the column label with special characters, and the fourth row is the column label without special characters (and it corresponds with the first row of the CSV file). Additionally, a browse graphic (sonde.jpg) and the CSDGM metadata in XML format are provided. The list of tabs (sheets) in the Excel file and the CSV files are organized as follows:
Sheet 'all' corresponds to CSV file all.csv and it contains all data records.
The following 9 sheets and 9 CSV files are separated by the time and place of the sonde deployment:
Sheet 'JAH_Dec13' corresponds to CSV file JAH_Dec13.csv;
Sheet 'ODY_Dec13' corresponds to CSV file ODY_Dec13.csv;
Sheet 'NWH_Dec13' corresponds to CSV file NWH_Dec13.csv;
Sheet 'CRU_Aug14' corresponds to CSV file CRU_Aug14.csv;
Sheet 'JAH_Aug14' corresponds to CSV file JAH_Aug14.csv;
