Through the ice, wire-walking profilers (McLane Labs Ice Tethered Profilers [ITPs]) were deployed in both lobs of Lake Bonney. Attached to the ITPs were sensors for dissolved CO2 (Pro-Oceanus XXX). The ITPs were programmed to profile once daily around regional solar noon. A profile consisted of one downward and one upward movement to the furthest reach of the profilers possible movement, or the bottom of the lake or bottom of the ice, whichever limit came first. During the profiles, CO2 concentration was recorded every XXX seconds. Because the CO2 sensor did not contain its own pressure sensor, pressure from the CTD endcap was matched with dissolved CO2 observations based on time.
