Hunting the doliolid and a leap of faith

Two of our scientists are taking our ocean-going research vessel, the R/V Savannah on a four day trip looking for the elusive doliolid (doe-lee-OH-lid).

“What is a doliolid?” you may ask, “and why do I care?” Good questions. These little critters are tiny, not quite microscopic, gelatinous (like jellyfish) organisms that look like little beer barrels.

They occasionally “swarm” on the continental shelf. The changing ocean environment, especially a falling pH, may create conditions ripe for these critters to proliferate. It would be nice to know what they eat, what eats them and how they fit into the whole oceanic food-web scheme of things. Right now we know very little.

Actually, I would love to go along on the trip, but I cannot justify four days at sea for about an hour’s worth of photography work. So I have turned over one of our institutional cameras to the marine tech and asked him to snap away.  In the past, I have not been very successful in getting useable photos from amateurs. (Not that I’m any great shakes, but I can get it in focus and properly exposed and framed frequently enough to get some serviceable photos.) Actually, our marine tech is a very sharp guy and so I am optimistic. I’ll let you know how it turns out.

  1. Your work sounds very exciting. I’ve never heard of a doliolid. (Spell check apparently hasn’t either.) Interesting looking creatures.
