Log Post: Deep Water Chemistry

This morning, R/V Falkor stopped at a deep-water site on the way to the first dive site, Okeanos Ridge, in order to deploy a CTD-rosette. CTD stands for conductivity-temperature-depth sensor. The instrument derives salinity from conductivity, depth from pressure, and temperature from an electrical thermometer. The ‘rosette’ configuration has 24 bottles associated with it, called … Continued

On July 24 and 25, researchers and the crew aboard R/V Falkor cast the Conductivity, Temperature and Pressure Rosette (CTD) to depths of 5,000 and 4,300 meters, respectively. The CTD casts took place about 300 miles east of Nova Scotia in some of the deepest parts of the Atlantic Ocean.  R/V Falkor ventured into waters … Continued

Dr. Michael Wetz, along with his undergraduate students are collecting water samples throughout the water column using a CTD (Conductivity, Temperature, and Depth) sensor. A Profiling CTD measures water parameters as it travels through the water as it is lowered over the stern of the Schmidt Ocean Institute’s Research Vessel Falkor. As the CTD travels … Continued

Log Post: Instruments of the Ocean Part Two: ADCP

Similar in shape to a fire hydrant, the Lowered Acoustic Doppler Current Profiler (LADCP) is fastened to the CTD (Conductivity, Temperature and Depth) Rosette, a white, jungle gym-like structure. Therefore, each ADCP drop also requires a CTD deployment. The ADCP itself is light and requires no special lifting equipment, but the CTD is quite heavy, … Continued

On its inaugural expedition, Falkor (too) will head to the Mid-Atlantic Ridge with Chief Scientist Dr. David Butterfield from the NOAA Pacific Marine Environmental Laboratory – University of Washington, and his team to search for hydrothermal lost cities. In 2000, scientists found a hydrothermal vent system on the Atlantis Massif unlike any seen before. Ghostly towers made … Continued

Investigating Life Without Oxygen in the Tropical Pacific January – February Data from sensors lowered on Falkor's CTD rosette will go to the Marine Geophysical Data System.M. Schrope Large-scale ocean circulation naturally results in low-oxygen areas of the ocean called oxygen deficient zones (ODZs). The cycling of carbon and nutrients – the foundation of marine … Continued

Log Post: Some days seem longer than others

A busy day today but also a strange one.  I was woken just after 5am by a feeling in my bones – quite literally, actually: the ship’s motion had suddenly changed which brought me alert and, in a matter of seconds I realized why: we must have finished the 2nd CTD station at Piccard – … Continued
