After a bumpy night of sailing from Kahe (West O‘ahu) to the south of O’ahu and Moloka‘i, avoiding [most of] the roughest seas in the channel, we have arrived at our target eddy of interest – a cyclonic eddy (shown in blue) just North of Maui. We have been tracking this particular eddy for several … Continued
Summarizing a cruise is one of the most difficult duties of a Chief Scientist. I could distill all our work down to a slew of metrics—over 600 chemical analyses for pH, nutrients, and dissolved gases, 312 CTD casts, eight incubator deployments, 325 deck board experiments, and 216 liters of filtered sea water. All told, we … Continued
Metals are present in our ocean, this is nothing new to us. Scientists have been measuring metals for decades and have a fairly good idea of their average concentration at different ocean depths. Some of these metals are very abundant, including ones that belong to the alkali metal and alkaline earth metal group, such as … Continued
This week Pete and I started doing our experiments with water collected from the CTD profiles.
“Have you ever done a XBT cast?” John Fulmer asks. I have not, but I am excited to learn about another device used for deep-water oceanography. He hands me a cylindrical tube fastened in a holder that looks a bit like a caulk gun. At the point of the cylinder is a small pin that … Continued
Up early again today for our first Nereus dive in earnest, heading down to 2250m at the top of Mt Dent, just West of the Von Damm hydrothermal field, for engineering tests. After a few concerns right before diving (waiting for the coffee to kick in and provide clarity) we were ready to go and … Continued
Check out the second video from one of our Student Opportunities participants, Jennifer Killinger. She takes a look at how Mixing Up the Tropical Pacific scientists on board Falkor are collecting oceanographic data with the CTD using Yo-Yo and Tow-Yo techniques.
How even ideal conditions at sea can be a challenge for a research vessel. The R/V Falkor is currently stationed at 1° North and 170° West, heading North, conducting a 10-day time-series, looking at small scale mixing throughout the Equatorial Pacific. Jennifer and I have been onboard for long enough to realize that conducting science … Continued
If you’ve been paying any attention at all to the news in the last, say, two decades, you will know that the temperature of the ocean is increasing.
Today I present another look at my art process aboard the Falkor. This unique residency presented a fantastic opportunity to focus and also brought unexpected challenges. Overall it has been an excellent learning experience. From macrobiology to microbiology and chemistry Before this voyage, most my collaborations with marine scientists have been with biologists studying relatively … Continued
