Brief description

This research was a manipulative experiment on a chartered fishing vessel that was chartered to control the confounding effects. Future users of the data should be familiar with the associated published paper, especially the Introduction (which spells out the context) and Methods. Users should also be familiar with the latin square experimental design and take note of Table 1 in the published paper. It would also help if they are familiar with the use of fine scale time-depth recorders in determining the sink times/rates of objects in water. There are three files attached. The first is an excel file called 'Line shooter headers for analysis'. This file includes the day number in the experiment, the numbers of the time-depth recorders, the CSV files, the treatments, deployment sequence, the water entry times and notes on data quality. Reference to the Methods section of the paper will clarify any uncertainties. The other two folders attached contain the TDR csv files.
