Abby and I have been through a lot in our seven years together. From the frigid cold-water coral reefs of the Arctic Circle to the very deepest part of the Mediterranean. Recently, me and Abby have turned our sites to deep sea trenches and have explored the Kermadec, New Hebrides and now the Mariana trenches. … Continued

Think about the last time you went for a swim in the ocean. If you’re anything like me you undoubtedly got water in your mouth, your nose, and your ears. Taste that? No, not the salt. I’m talking about the 10 million microbes you just got in your mouth. Every milliliter of seawater contains approximately … Continued

The world is full of natural wonders that delight our eyes and inspire our hearts: the mountains of New Zealand, the redwoods of California, and the hadal snailfish. Hear me out on this one. The hadal snailfish may not look imposing or impressive at first glance. Small and translucent, they glide in the ocean’s unseen … Continued

I’ve always been a fish person. Like many, I have long been captivated by the colorful triggerfish and wrasses of the reef, the coiling strangeness of wolf eels and sixgill sharks, the complex camouflage of flatfish and sculpins, just to name a few. I was never much interested in invertebrates beyond octopuses, one of the … Continued

This is science so we can’t be shy – let’s take a closer look at gonads. This is science so we can’t be shy. Gonads are sexual organs; females have ovaries and males have testes, and collectively they are called gonads. My job on this cruise is to collect the gonads from any hadal invertebrates … Continued

In short, yes you do!  The expedition thus far has been so much fun. Falkor is a marvelous ship that is both comfortable for living and beautifully well-equipped for science. So now the question remains, how do you get onto a ship like Falkor? Well, you could go as a scientist, but they are not … Continued

So the sun rises on another day of science. Science itself doesn’t sleep and throughout the night the ship has been slowly mapping over our next deployment site some 9km below us. This brings me to my first observation of the day. One of our scientists asked me what the depth was below the ship … Continued

Research into the deepest ecosystem on Earth is currently in somewhat of a quagmire. The technical challenges of the past no longer exist and the last 10 years have seen a renaissance in biological exploration at full ocean depth. However, with ever more sophisticated technology at our disposal, a discrepancy has emerged between opportunities to … Continued

The deep ocean trenches like the Mariana are fascinating places to study evolution. For species to be able to survive and thrive in the extreme environmental conditions of the hadal zone they must have accumulated a whole suite of adaptations, which ultimately will make them very different from their non-deep sea counterparts. Indeed, it has … Continued

If you have ever played in the mud as a child and were consumed with delight then you’ll understand how this expedition feels for me, it’s all about the mud! The sea floor of the Mariana Trench is a mixture of geological features, including exposed rock and areas of soft-sediments.  These soft-sediments are mostly made … Continued
