When phytoplankton (the single cell plants that live in the ocean) perform photosynthesis, they take up CO₂ from the atmosphere and convert it to organic carbon that becomes food for other organisms and put out O₂. When the carbon “fixed” by phytoplankton ultimately sinks to the bottom of the ocean, it can be considered removed … Continued
My name is Carson Witte, and I have been on this ship since before Halloween. Wait – this cruise did not start until late November! Why have I been onboard longer than most of the crew, and what have I been doing? Well, here’s the story… Combining Datasets The headline feature of this research cruise … Continued
My name is Una Miller and, as a PhD student at Columbia University, I study how the ocean and atmosphere interact. On this research cruise, I am acquiring infrared (IR) imagery of the sea surface that will allow us to study the precise boundary over which this interaction occurs… the cool-skin layer! Visualizing The Invisible … Continued
My name is Kelly Luis and I am a PhD student at the University of Massachusetts-Boston. I study ocean color from remote sensing platforms and on this cruise, I am ground-truthing ocean color measurements from UAVs and satellites. Hawaiian Blue Water Growing up in Hawai’i, the ocean’s blue hues were the backdrop to my childhood. … Continued
World firsts, trichodesmium slicks, exciting deployments, skillful recoveries and a few sharks to boot; the past week or so has flown by (quite literally). With so much action packed into such a short period of time, we have to remind ourselves that there are still a few weeks to go! As we begin week two, … Continued
Rising water temperatures and increasing carbon dioxide concentrations remain among the greatest threats to ocean ecosystems globally. This warming trend and associated ocean acidification poses a unique threat to species that use calcium carbonate to build their shells or skeletons, such as corals.
Picture Mount Everest, and, on top of that, add One World Trade Center four times over (~36,000 ft total), now imagine a credit card (~1 mm) sitting on top. The former gives some sense of scale for the deepest point on planet Earth, the Mariana Trench; the latter is the thickness of the sea surface … Continued
14 November 2019 marks the bittersweet conclusion to my journey on board the Research Vessel Falkor. As we continue to approach the final destination of our 2,745 nautical mile transit, I am both grateful and overjoyed to have been able to gain the full experience of living life at sea, and I am sad to … Continued
As we pass the midpoint of our cruise, and after, quite literally, sailing past ‘hump day’, it is time to take a look over what has been achieved over the last few days. Following a ~15 hour transit to our first site on Tuesday, and continual observations for whales throughout daylight hours, work began at … Continued
ROV SuBastian, the Research Vessel Falkor’s Remotely Operated Vehicle, is designed for the efficient collection of scientific data at depths up to 4500m. The yellow robot is currently being used to understand the similarities and differences across large features of the deep sea. Recently, researchers have asked, are the communities on either end more similar … Continued
