For the past two weeks we have dredged, dragged, hefted and hoisted
lava from the seafloor around Fernandina and Isabela. Lovely,
black, shiny rocks, glittering with green-yellow and white
crystals: olivine and plagioclase - the most common minerals
in the ocean crust. Some of the lava flows have a glassy surface.
Others are bulbous blobs molded into shapes showing how the
magma moved as it erupted from the seafloor.
Weve pulled them from the dredge, whacked them with hammers, chipped
them to little bits, and sawed them in thick slabs and tucked
them away in bags and buckets.
We are thriving amongst rocks. We are in a
word: rupicolous. (Pronounced: roo-pick-o-lus.) No kidding...
that's a real word and it fits us perfectly out here on RV Revelle.
Every four to five hours, even at night, the dredge comes up from the
seafloor filled with treasures. Mostly, we find rock treasures. But sometimes,
especially in the shallower areas, we get animals, too. Rhian Waller
and Kate Buckman, our resident biologists, are thrilled with some of
We have three different species of brittle
stars and nine individuals, two sea stars and a fan worm, which
lives specifically on rocks. We also have some non-rock thriving
We have jelly balls! Rhian says. I've only seen them in pictures
before. Tiny little balls of jelly, they are really small animals called
ctenophores, which are related to the jellyfish and swim in the ocean currents. You
can tell each species by the pattern of bioluminescence they show.
Today we pulled up 12 giant, thick-skinned
anemones called Phelliactis robusta. Its a cosmopolitan anemone found in both the Atlantic and the Pacific Oceans
that lives in the sediment. Kate was over the moon when she saw them, Rhian
says. She and Kate are careful to preserve and catalogue our biological critters
so they can be carefully studied back at the lab.
In a couple of weeks, our rocks will find new
homes amongst the collections of various scientists. The largest
samples of pillow basalts will help provide material for many
researchers to come, so they can be rupicolous, too!
