The oxygen minimum is still clear, but the layer seems to be getting thinner (250 m vs. 300 m). My plan is to continue offshore until sg157 exits the OMZ or 71.5 W.

MOOMZ 3
sg157 continues to head offshore almost to 71 W now. For the last ten dives (85-95), sg157 has been collecting chl, backscatter and cdom observations over the entire 1000 m. I have now turned off the optics after 600 m depth. This deep water should have minimal signals (i.e. zeros), and will provide a means for Amanda to estimate drift in the optical measurements.

Thanks, Kipp! Maybe the data at 1000m won't look very different than at 600m, but a few more track lines with deep data offshore ought to tell us for sure. The data are looking fantastic!
