Thanks, Jay. Flotec is a partner with Teledyne/RDI and sells a variety of ADCP deployment products including the buoys made for their ADCPs.

Here's another article that sheds some more light on their use:

I. INTRODUCTION
Strong ocean currents can disrupt various deepwater activities
and cause downtime for hydrocarbon exploration and production
activities. Thus, accurate and timely observations can help with
planning and assuring safe operations. Remote sensing cannot
always be counted on to provide timely observations of the sea
surface and is not a direct measurement of ocean currents.
Drifting buoys have proven to be a cost effective means of
collecting ocean current observations; however, drifters report
only near surface currents and the Lagrangian technique does not
provide a means of activity targeting and monitoring a specific site
or area. Acoustic Doppler current profilers (ADCP) mounted on
moorings and platforms can provide real-time current information
but are not always optimally located. ADCPs deployed on ships
provide the most viable way to survey ocean current profiles.
Only a shipboard ADCP can be used to collect ocean profiles
while underway and thus provide surveys of synoptic ocean
features. Deepwater current profiling requires a low-frequency
ADCP operating at 38 or 75 kHz. Traditionally these large
systems have been hull mounted systems mostly deployed on
research vessels. When care is taken, the hull mounted system
operates in a low-noise, bubble free environment and provides
optimal performance. However, the system is tied to a single
vessel.
In this paper, we report on the development and performance
of a towed body with a 75 kHz ADCP. This application provides
a system that can be easily relocated and deployed for various
vessels, yet provides a very quiet, stable platform for the ADCP.
