The physical oceanographers on board have been so patient this entire cruise, staring thoughtfully at their computer while they wait to find internal waves. Finally, I am happy to report, we finally found some, at 6AM this morning (we are due to dock at 9AM). No time like the present. The ship steamed into more shallow water, and lo and behold, internal waves! This just goes to show that good scientists always have tenacity and never give up trying to find great things.
Here is an image of the internal waves.
