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
As ocean temperatures increase, a pressing global challenge in marine science is to better understand the distribution and characteristics of the critical habitats that support mesophotic and deep-water coral communities.
Mariana looks at the buoy drifting away from R/V Falkor. She has done it countless times before; but as she assists in the deployment of the snifel off of the ship’s aft deck, the familiar anxiety comes back all the same. Designed to measure the speed of the exchange of carbon dioxide between the atmosphere … 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
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
This expedition will feature exploration of the Emperor Seamount Chain while researching biodiversity and its drivers. Using currents, mapping, and radio isotopes to track water masses – as well as genetic sampling of corals – the team will determine the driving force behind coral distribution in this region.
This morning at 0900, after two full days of loading and prep, Falkor slipped the dock and headed north out of Nanaimo into the central Strait of Georgia. Just north of the Departure Bay – Horseshoe Bay ferry route that runs from Nanaimo to toward Vancouver, the ship parked for some critical equipment tests. The … Continued
As the old saying goes, “Where there is smoke, there is fire.” This is the approach researchers on R/V Falkor are using: searching for particles and chemical signals as tracers of plumes. The chemistry of seawater around volcanoes is different from that of the rest of the ocean. When the team runs into these differences over … Continued
Although we were able to collect the missing ROV part this morning, there is yet another obstacle to clear before we can explore the Canyon for the first time. As soon as we headed back out to the open ocean, we were met with strong winds and swell that persisted throughout the day. This wild weather … Continued
The sea is constantly changing, and today, it was a shift toward the rough side, as the forecast for gale force winds proved accurate. Work continues, but with a few further shifts to plans. Until today, seas had been calm, making it easy to climb the four decks up to the observation platform to watch … Continued
