Today we had another deep dive, reaching 2,000 meters (6,561 feet), searching for deep-living animals that we rarely get a chance to see. We also had the chance to collect some of our target animals, like Octopoteuthis deletron.
In yesterday’s blog, I talked about the importance of studying midwater communities and the oxygen minimum zone (OMZ). I also mentioned that as the ocean warms due to climate change, OMZs are expanding. Why is that, you might ask? There are a few key factors in this expansion.

Researchers’ top priority for the cruise is to measure the sensitivity of deep-sea crabs to ocean acidification and low oxygen levels, two consequences of fossil fuel emissions to the atmosphere—it is amazing to think emissions are affecting animals at the bottom of the sea.
While the ROV and AUV surveys are the priorities for this research expedition, as per the multidisciplinary nature of this mission, we are constantly designing other science tasks that are undertaken as time allows.
We recovered two AUVs during the first several hours of the morning. At 10:30 a.m. the MiniROV arrived at the seafloor at a depth of 240 meters. The mission objective was to ground truth a slump scar using the video camera on the ROV.
Research programs at the Monterey Bay Aquarium Research Institute (MBARI) encompass the entire ocean, from the surface waters to the deep seafloor, and from the coastal zone to the open sea. The need to understand the ocean in all its complexity and variability drives MBARI's research and development efforts.
