Search Results for CTD
Like a bloodhound on the scent, the recent discovery of our first new vent site energized our exploration efforts. Our next target site was on Map 5, which shows two shallow “saddles” separated by deep basins. These high points correspond to places along the Mariana Back-arc where an enhanced supply of molten magma over hundreds of … Continued
Lots to tell you about today. We started off with a CTD coming on deck from the furthest north point we have been to (and also about as unpromising as can be) since we started our latest search. Then, because Casey and the Nereus team needed to do some engineering work on the back deck … Continued
This morning at 0800, Falkor arrived at the entrance to Juan de Fuca Strait on her way offshore. There was a little fog, but everyone was pleased to find relatively calm seas in the 2-meter range. The acoustic Doppler current profiler ran all night during the steam from the Straight of Georgia, through Haro Strait, … Continued
Like a domino effect, several things happen to seawater when it comes in contact with a volcano. When a volcano is not erupting and there is hydrothermal activity, hot water with very different chemistry from seawater rises up, just like steam would over a boiling pot. It spreads out and begins to create particles, or … Continued
Oceanographers, marine biologists, acoustic researchers, a Student Opportunities Participant, and an Artist-At-Sea: the team of the ‘Listening for Cryptic Whales Species’ cruise has come on board for an exciting cruise that focuses on investigating species of whales around the main Hawaiian Islands. This includes species of beaked whales, which have been called “the least understood … Continued
My name is Kate Malloy. Despite being an undergraduate student from James Cook University studying marine biology, I recently learned to look past all the fish in the sea on a student exchange to Hawaii and began to develop an interest in physical oceanography. I am currently on board the R/V Falkor learning how to … Continued
Kaena Point on the island of Oahu feels like the end of the line for many island residents.
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
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
