Today we are sharing some photos with you that do not include rocks. The morning watch folks woke up to a decorated lab (by the night watch team) and signs that celebrated the mid-point of our, so far, successful expedition. That not rock statement above- well, it is not entirely true but there is only one photo from the spectacular and, this time, the very delicate geology of the ocean floor! As a tradition in research cruises, we sent some polystyrene cups in a plastic net to a depth of ~ 3,600 m (~ 12,000 ft). See the crushed cups when they came back up. A beautiful rainbow and a cute little bird added more joy and color to our day. In the last photo, Captain Dave Murline is pointing to a pod of (possibly) pilot whales. Come back again to see amazing photos of the whales breaching the water behind the rainbow.
