Aaaaand, we’re back!

(Photo: Kelly J. Owen) The Oceanus tied up at Pier 30-32 in San Francisco at 7:20 a.m. on Tuesday, Aug. 23, and we are still getting our land legs back. The time at sea has ended, but the work to compile and analyze the data collected is just beginning.

The researchers will look for clues about the seasonality of plankton populations in waters off the coast of California. And the engineers will continue to update the functionality and design of the robotic floats as ocean monitors of the biological carbon pump.

The Support Crew Behind the Science

The Oceanus crew members come to the ship from a variety of backgrounds. Many have worked with the Navy or on fishing vessels and tug boats. There is easily more than a hundred years of experience among its crew members. Read More »

Motoring back home

Spooling-Cable960We are nearing the end of this 10-day research trip, and as I’m writing, people are bustling around me in the process of deconstructing the labs they set up and packing up their gear. Researchers have made backup copies of the data collected from the various tests conducted, the Carbon Flux Explorers are tucked away in their crates, 700 meters of cable were unspooled from the ship’s winch back onto a reel by hand, and filtering and processing stations – including the “Bubble” – have been taken down.

Oceana Incognita

The waters were clear enough to see the CTD from 30 meters below the water's surface. (Photo: Sarah Yang)Outside the California Current, the last few experiments are being run aboard the Oceanus at a place Jim Bishop calls “Oceana Incognita.” The nickname came about because the location feels like the middle of nowhere and has not been observed by satellites for the past six weeks.

The contrast with the coastal waters at the Santa Cruz Basin is striking. When the top layers of water are not teeming with phytoplankton, the blue color of the water can shine through. Just as the chlorophyll in leaves absorbs the color blue, making them appear green to us, the chlorophyll in phytoplankton gives the water a more greenish hue. Had we been in Santa Cruz Basin in May, the concentrations of chlorophyll would have been 10 to 20 times higher than what we saw this trip. Read More »

So What’s It Really Like Doing Research on a Ship?

Jong-Mi Lee, Yang Xiang and Phoebe Lam of UC Santa Cruz process samples in their “Bubble” on board the Oceanus. Setting up and organizing the various lab spaces take up a large proportion of the time spent loading a ship. Phoebe Lam’s “Bubble” and Jim Bishop’s clean air-water filtration station are examples of spaces that the researchers need to ensure that the samples they collect are not contaminated.

When the researchers are not out on deck deploying or recovering equipment, they are often found in the main lab area working with the samples or the robotic floats. Read More »
