If you look at our recent GPS trajectory, you might think our navigator is, well, under the influence.
But actually, our course is a planned path between 3 specific spots:
Da Base: Our home base for the past few days.
Da Hole: A location slightly south of Da Base, where the satellites showed chlorophyll levels looking a little low.
Da Hump: A spot slightly north of Da Base, where the satellites indicated chlorophyll levels were a little higher than the surrounding areas.
So we started at Da Base, went down to Da Hole, back to Da Base, up to Da Hump, back to Da Base, down to Da Hole, back to Da Base, and now we’re heading back to Da Hump. You get the idea. If you’re confused, it’s okay. So are a lot of people on board! A common question the past few days has been, “Wait, where are we again?”
The idea is to go to a place (like Da Base), and then poke around for a while, taking different measurements. With the help of satellites, we can see where there might be something interesting — like low chlorophyll levels at Da Hole or high chlorophyll levels at Da Hump — and we can go there to check out what’s happening by deploying instruments like the CTD, different profiling floats, nets and traps.
Right now we’re steaming north…up to Da Hump again. From there, we’ll go farther north, where there’s something the scientists are tentatively calling “the promised land” where there seems to be a big bloom of something (hopefully Ehux!). We won’t know until we get there though.
The hunt is on!
During this trip, I’ll be answering your questions about the science, this boat, and life onboard. Want to know how we search for plankton, why we’re here, or what the food is like? Just ask me! And if you’re wondering how I got here, check out the groups that made this adventure possible: Mind Open Media and COSEE NOW.
