A Profiling Float Becomes Clear Mbari Mbari researchers ken johnson and hans jannasch created a transparent, nonfunctional version of a profiling float, an instrument that makes biogeochemical measurements in the ocean, for educational purposes. The soccom project is in the process of deploying a large network of profiling floats equipped with oxy gen, nitrate, ph, and bio optical sensors in the southern ocean. determining the impacts of climate pro cesses on carbon flux is a major goal of soccom.
A Profiling Float Becomes Clear Mbari "peering into the insides of a machine can be a useful way to learn about how it works. mbari researchers ken johnson and hans jannasch created a. Floats can operate in the harshest environments, providing unequalled datasets. bgc argo floats with ph sensors can provide an estimate of pco 2. almost all socat data is summer time. ship board data is essential to validate float observations. opportunistic contributions from go ship are key. These new floats sit on the seafloor between profiles. this allows the floats to resist being moved by the currents when it is not collecting data.

At the present time task 1 is well underway, with a prototype of an improved o2 sensor designed, built, and deployed on a profiling float near hawaii. task 3 is also in progress, with laboratory tests at seabird underway. Here we present a methodology and accompanying software designed to easily visualize float data against select reference datasets and assess qc adjustments within a quantitative framework. We present a lightweight (17 kg) and low cost (6000€) instrument for autonomous profiling across the strongly stratified upper layer in arctic coastal waters, freshened by the riverine input and meltwater from glaciers, icebergs, and sea ice. The gains in energy efficiency have had two major impacts on experimental design: enabling deeper profiling for salinity calibration checking, and increasing the profiling frequency to a profile per 10 days, without compromising float lifetimes.
