Today’s dive investigated a steep wall face along the southern side of Hendrickson Canyon. Remotely operated vehicle Deep Discoverer (D2) reached the boulder-strewn bottom at a depth of 1,670 meters. As D2 moved upslope along our transect, the sheer canyon wall was characterized by several scrapes on the chalky wall surface, evidence of previous failures (some recent), several chutes, and occasional manganese staining. By far, the most abundant fauna of the dive were cup corals, which were generally located under frequent overhangs and outcrops along the sheer wall. Other common fauna encountered along the transit upslope included several species of octocorals, black corals, scleractinian corals, fish, octopods, sea pens, corallimorphs, sea spiders, sea urchins, and sponges. Highlights from today’s dive included a dandelion siphonophore, an acrobatic chimaera, a large vertical crack that had a high diversity of corals and sponges as well as several octopods, and the first deployment of D2’s new sediment probe, affectionately called “Sepoke.”
