Search Results for CTD
One of the joys of exploration is getting surprised. And boy, were we surprised when we found a lava flow on the seafloor that looks like it could have erupted yesterday! It is right in the area where we found big plumes and the most intense chemical anomalies during the last CTD tow-yo on what we … 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
After a first week of dodging a typhoon, hanging on during rough seas, and ironing out minor equipment problems, we are now reaching our stride and have made our first hydrothermal discovery in the Mariana Back-Arc. After leaving Guam, we have been proceeding roughly from south to north. To organize our search, we have divided … Continued
Today has been a quiet day but we’ve been making steady progress. The first CTD cast started at 4am and the last of the day will finish just before midnight. Tomorrow we will start again at 04h00. Working to that pattern we have managed to measure water column properties from top to bottom at three … Continued
So, we are at the halfway point of the trip already! As mentioned in my previous blog, we are off the coast of Exmouth (Western Australia) on a voyage aiming to document the biodiversity of the Ningaloo Canyons (Cape Range and Cloates). These submarine canyons are unexplored ecosystems, therefore this expedition has the potential to … Continued
Today’s work was a study in classic oceanography that took the team to the source of the lower-oxygen water that is the focus of the expedition—and it all came with some beautiful views. There are more and more whale sightings, and albatross are constantly skimming the surface of the waves, which remain reasonably calm. During … Continued
The term Saildrone brings to mind images from opposing ends of the human timescale: sailing – one of the oldest modes of travel – and drones – arguably the most rapidly evolving industry in modern transit. In a nutshell, this juxtaposition is the exact function and purpose of a Saildrone—combining the efficiency and sustainability of … Continued
As we begin our transit back to Honolulu, Student Opportunities participants Julianna Diehl and Jennifer Killinger have time to reflect on the cruise and their experience. What was the biggest challenge for you while on Falkor? Julianna: After getting onboard Falkor, I was determined to learn and absorb as much as I could from each … Continued
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
It was a magical feeling when the image appeared on the screens. The researchers in the Science Control Room were beyond excited: “This is just like finding a unicorn. You hear about them, some people even believe they exist, but you never expect to come across one,” said Dr. Mak Saito, chief scientist. This particular … Continued
