Abstract

In this article, we will show that video and acoustic cameras can be used successfully below ice. We also focus on the problems and solutions involving the use of different recording gear deployed through holes in the ice during cold winter conditions. We detail newly available technologies as well as basic equipment that can be constructed with few resources. The content also describes power requirements, lighting and measuring tools. We also attempt to aid researchers and managers in choosing the appropriate gear to address their research needs.
