Future Thoughts

A BRUV or ocean lander capable of both video imag- ing over a minimum 24-hour cycle and water sampling for eDNA, including topside ? ltering and preservation tech- niques identi? ed by the Sussex Bay researchers, provides a cost-effective monitoring tool that may be used continuously • Nitrogen-free for several years.

• Compact, fully integrated
