Entity_Type_Label: CenoteBangSondeData_2013-2016
Entity_Type_Definition:
Data from diver sonde deployments in the Cenote Bang, which is part of the larger Ox Bel Ha cave network. The profiles were conducted along vertical profiles in the water column of the caves and cenotes using a YSI XLM-600 (Dec 2013, Aug 2014 and Jan 2015) or an EXO2 multi-parameter datasonde (Jan 2016).

Entity_and_Attribute_Overview:
These data are also available in a XLSX format. The first line of the CSV file is a header line and those labels are the same as the fourth row of the Excel spreadsheet. The first row of the Excel spreadsheet contains a header line that includes the month and year the data were obtained, the second row indicates the sonde utilized, and the third row is the same information as these attributes, but some columns include special characters. The Excel spreadsheet has 4 individual sheets, all containing the same row and column information. Each sheet represents data from a different sampling event.
Sheet data_Jan'16 corresponds to CSV file CenoteBangSondeData_Jan2016;
Sheet data_Jan'15 corresponds to CSV file CenoteBangSondeData_Jan2015;
Sheet data_Aug'14 corresponds to CSV file CenoteBangSondeData_Aug2014;
