Maybe it’s not the local processes | Weekly Research Update

I think I’m beginning to make a breakthrough! More details below.

Another thought: What is influencing the extreme low DO concentrations in the inlets? In this analysis, I have only considered the average layer concentrations.

This is great! That conclusion is not obvious to me. In fact we set out on this investigation looking specifically at the characteristics of the inlets that we expected to influence hypoxia and we didn't include inflow DO! I would also note that it is probably not the only ingredient that is important. The comparison between Case and Car inlets shows that volume/depth matters too. And, it seems like inflow DO may only be important in inlets where the recirculation is high. Are there inlets in which this is not true? Is there less recirculation in Dabob, for example, which is also connected to Hood Canal (albeit further to the north where DO may be higher). It might be an interesting one to add to the comparison.

I really like Fig 3, by the way. It makes it clear that there are not profound differences in the magnitudes or rates of change of DO in these inlets (with the possible exception of Budd).

Thanks for your thoughts! I like the idea of adding Dabob Bay to the mix. I agree that there's probably more going on, and I'll think about how we can explore this idea of depth/volume. I'd also be interested in combining these newer results with the scatter plot analysis I was working on previously.
