Brief description

This research was a manipulative experiment on an autoline toothfish vessel in the Ross Sea testing the effect of a line shooter on the sink rate of autolines. The vessel was production fishing during the trial. 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 use of time-depth recorders (TDRs) in determining the sink times/rates of objects in water. There are two files attached. The first is an excel file is the results of the TDRs. It shows the pairs (ie., AA, BB etc), the TDR numbers, the colour coding to avoid confusion in line setting, the code dealing with the attachment position of TDRs in magazines and the time in seconds to target depths. The other file contains all the TDR records. There is one record per TDR deployment. The summary of the times to depth is included near the top of each record. It is a simple head-to-head comparison.
