Control System for Low-Cost Miniature Isopycnal Floats (Minions) Targeting Distributed Observations of Theoceanic Biological Carbon Pump

Abstract

The flux and attenuation of Particulate Organic Carbon (POC) export through the mid-water column has been a subject of oceanographic research for decades. The methods to sample sinking particles have remained largely unchanged, and interpretation of the data is challenged by uncertainty and sparse measurements. This need prompted our efforts to develop a standalone sensor platform for subsurface timelapse photography of accumulated particles as a proxy for carbon export, combined with simultaneous measurements of dissolved oxygen, temperature and pressure. The use of a flexible Linux single board computer with power cycling enabled the float to be; low power (for long term deployments), low cost (to be deployed en-masse), easy to operate (to be deployed opportunistically by other scientists) and flexible for future expansion and improvements.
