Six things I learned about Giant Isopods while Sizing Ocean Giants

January 13, 2015January 13, 2015 Andrew Thaler 4 Comments

Science

Today, Craig McClain, along with a massive team of ocean scientists (including me!) published our monumental paper: Sizing ocean giants: patterns of intraspecific size variation in marine megafauna. This massive monograph investigates patterns of size among 25 ocean giants, the biggest, most massive members of their respective taxa. You can probably guess which species I had a hand in reviewing.

Along the way, I learned quite a few cool things about the magnificent giants of the deep sea.

1. Giant deep-sea isopods are sexually dimorphic.

In both my professional and private life, I am a man who wears many hats. I am a deep-sea ecologist, a science writer, a goatherd, a geneticist, a conservation advocate, a grill master, and many others. When David asked me to join him in co-authoring “Trophy fishing for species threatened with extinction: A way forward building on a history of conservation” I did so not in my capacity as a marine science Ph.D., but as a recreational fisherman who cares deeply about the survival of his sport. Without fish, there is no fishing.

I was, at first, skeptical, but over the course of a summer, I came to appreciate what David was trying to accomplish.

I wrote most of my thesis on this boat, with a rod in the water.

Before I talk about fish, I need to talk about birds.

The era of the million-dollar tuna is over.

For the last several years, we’ve been following the first-of-the-year Tsukiji Tuna Auction. In the past, this auction has served as a (often questionable) benchmark for the demand for Bluefin Tuna. At its peak, the price of Bluefin Tuna broke the scales at nearly $1,800,000. As the price continued to inflate, last year we even released an early warning to journalists covering the auction, cautioning them against drawing too many conclusions about the expectedly massive auction price. We we’re all caught off guard when the price of the first fish barely topped $70,000 dollars, kilo-for-kilo not even the most expensive fish sold that day.

Today, the numbers are in, and the first Bluefin of the year sold for a measly $37,500, barely enough to cover the cost to fuel for a fishing boat.

The era of the million-dollar tuna is over.

Southern California is basically Mordor: Climate forcing effects in Middle Earth

Middle Earth could have been saved by the Endangered Species Act

In a cave in the Lonely Mountain there lived a dragon. Not a gnarly, goblin-stuffed, slimy cave, filled with the bowels of orcs and fishy creepers, nor yet an empty, granite, echo-less cave with nothing in it to lie down on or horde: it was a dragon-cave, and that meant gold. At least it did, until a nasty band of poachers found Lonesome Smaug, the last of his species, alone, asleep, threatening none, and smote his genus from the red ledger, stripping Middle Earth of critical biodiversity.

The ecologists of Carsondell would say, of the age of war that followed, that the men and dwarves and elves and hobbits brought the darkness upon themselves. Indeed, as the Dark Lord raised his army, denuded the forests, and belched carbon from the factories of Mordor, Gandalf the Grey, one of the more powerful, though among the least conservation-minded, of the wizards would remark: “It has been said that dragon-fire could melt and consume the Rings of Power, but there is not now any dragon left on earth in which the old fire is hot enough.”

The Grey Wizard failed to mention that, were it not for his callousness, there would be*.

There is 10,000 times more plastic in the deep sea than in surface waters.

Ocean plastics is one of the most pernicious problems facing the ocean. One-time use plastics, which, ironically, can persist for thousands of years, often find themselves carried downstream, settling on our beaches, our coastlines, and in large aggregations within oceanic gyres. We’re still trying to cope with the extent to which plastics, and particularly microplastics–tiny photodegraded plastic particles, impact marine ecosystems. Earlier this year, ocean plastics made major waves when it was reported that not only do we not know how much damage they really cause, but we don’t even know where most of them go: 99% of the plastic that should be in the ocean is missing.

It looks like we found the missing plastic.

Andrew’s five favorite “new” ocean blogs

Several years ago, the ocean blogosphere experienced a moment which can only be described as a Great Convergence. Numerous popular independent blogs, either seeking refuge from The Event, looking for a broader audience, or undergoing life transitions that made it impossible to maintain the high volume of new content, merged under the aegis of the Southern Fried Science/Deep Sea News aegis. For a while, the ocean blogosphere felt empty, with few giants roaming the internet depths (once one-man shows, Craig McClain now shares Deep Sea News with 8 current writers, the addition of Michelle Jewell brings Southern Fried Science up to 11). For a while the mighty Sea Monster filled the void, but they have slowed in recent months.

I miss the days when we had to check a dozen links each morning for the latest and greatest in ocean science writing. Fortunately, as often happens when ecologic niches are left empty, new species emerge to fill them. There is a new crop of excellent ocean blogs rising up from the deep. Here are five of my favorite new* ocean blogs that you should already be reading.

Ocean things we’re thankful for, West Coast Edition

As some of you know (especially if you follow us on OpenExplorer), Amy and I have once again made the vast, continent-spanning migration from the Pacific to Atlantic coast, this time settling down in rural Virginia. While we enjoyed our time out in the weirdly foggy, impossibly dry San Francisco Bay Area, we also learn that the southeast US is our ecological niche. Even so, we met hundreds of new and interesting people, got to play with some tremendous tech, and had a great time. So here are the top five San Francisco Bay Area ocean things we are thankful for.

1. Vallejo

Of all the cities that comprise the “Bay Area”, Vallejo, the smallest and furthest from the heart of San Francisco, feels the most maritime, by far. With a downtown only blocks from the waterfront, an expansive city park right at the edge, and an active ferry terminal for commuters, people with a nautical cut to their jib will feel right at home. Though smaller and more suburban than most Bay Area cities, it’s also a whole lot cheaper, with 2 bedroom houses renting for the cost of hot swapping* a futon in San Francisco.
