I guess this is what it takes to measure sinking velocities and remineralization rates of marine snow at in-situ conditions. At least, we don\u00b4t actually have to hop into the freezing cold fjord to do so.<\/p>\n\n\n\n<p>After a rather \u201cslow\u201d start to the experiment, the first data is coming in and the last tweaks to the methods are done here and there.<\/p>\n\n\n\n<p>The two parameters we are testing are crucial to estimate the depth attenuation of the biological carbon pump. How much of the biomass produced in surface layers will sink to the deep ocean?&nbsp; How will ocean alkalinity enhancement change this depth attenuation? Will calcifying organisms speed up sinking velocities or reduce remineralization rates? This will largely determine the CO<sub>2<\/sub>-sequestering capability of the biological carbon pump. To responsibly implement ocean alkalinity enhancement as an active carbon dioxide removal technology, we need to understand it\u00b4s influences on the biological carbon pump.
