Some of the most striking features of the deep sea are the amazing oases of life found at sites of hydrothermal venting. Elsewhere in the deep ocean, there is a low density of animals due to the fact that food is less abundant with depth, and thus, there is not enough energy to sustain a … Continued
Science and art are deeply related. Both involve looking hard at what is around us: taking time to observe and collect information to filter through brains. Art asks questions, science seeks answers. I have been drawing and painting since I was a child. I studied art in college and took it with me everywhere afterward. … Continued
Julianna and I have been sailing on Falkor for a few days now. The science team is all settled in as we make our way towards the first sampling location. The transit from Majuro will be approximately three days. As the scientist’s calibrate their instruments and prepare for arrival, the ship’s crew is all action … Continued
We are studying the oceanography of the Texas coast, focusing specifically on the distribution of phytoplankton and nutrients in the water column. High nutrients often set the stage for growth of phytoplankton. One particular species that we are interested in is the toxic phytoplankton called Karenia brevis. These algae could be identified in samples taken … Continued
Plankton comes from the greek word planktos, meaning wanderer. It does not define a specific organism, but rather a specific life style. Plankton consist of all organisms dispersed in water that are passively driven by water currents or are subject to passive sinking process. Some of those organisms have an ability to produce oxygen and sugars … Continued
Moving a laboratory onto a ship is no small feat. Multiple days are required just to transfer gear from shore to ship. It’s somewhat similar to moving from your own home to a dormitory, where more people share smaller spaces. On top of that, your schedule is always different, often times working in the evenings … Continued
Melissa Omand, interdisciplinary physical oceanographer from the University of Rhode Island’s Graduate School of Oceanography, was confronted with a conflict: it was time for an upgrade to her phone, but creating more technological trash did not feel right. Plus, the camera on her older phone was fantastic. Together with her first graduate student Noah Walcutt, she worked on … Continued
Trying to understand a constantly moving ocean system is a huge challenge. Accurately measuring the chemistry of the ocean is important for understanding many processes, including nutrient and carbon cycling; ocean circulation and movement of water masses; as well as ocean acidification and climate change. On this expedition, the water chemistry team has the important … Continued
Microbes play many vital roles by physically and chemically changing their surroundings: they consume and produce a diverse range of organic and inorganic materials, provide food for other organisms, and drive biogeochemical cycles on a global scale. Our research in the Cunliffe Group based at the Marine Biological Association in Plymouth UK focuses on understanding … Continued
Far offshore Queensland Australia, in the Coral Sea Marine Park, is a seafloor full of clues for understanding the complex geologic history of the Australia and the submerged Zealandia continent.
