Is there a shortage of oceanographers?

May 13, 2009

My father (Hi, Dad!) sent me this NYT article on the Rutgers University glider program. Gliders are little ocean-going robots that dive down, take measurements, and surface to email their data back to you. Since ship time is so expensive, having a glider noodling about on its own is incredibly helpful in figuring out what the ocean is doing. The NYT article definitely brought home the “gliders! yay!” message, but what excited my father was this:

Through its novel glider program, Rutgers is trying to drum up interest in ocean science at a time when federal officials are alarmed about a shortage of scholars in a field considered crucial because of growing concerns about ocean health as a result of climate change and overfishing.

The federal Departments of Commerce and Education, in a report last fall focusing on a branch of marine science that assesses fish stocks, said the National Marine Fisheries Service was “now experiencing a perfect storm.” Citing many imminent retirements, an increased workload and a “decreasing supply” of such scientists, the report called on Congress to bolster financing to expand the number of graduate students.

Really? This doesn’t really jive with the grad student scuttlebutt about the job market – it’s hard to find reliable work. Many of the federal agencies hire postdocs on 1-year contracts, which is extremely stressful for people who need a steady income to raise their family. But nothing would make this grad student happier than the promise of good employment in about 3.5 years, so tell me I’m wrong!


My Double X debut: dolphin smackdown!

May 13, 2009

ResearchBlogging.org

My very first blog post at the new Slate spinoff Double X is up. As Double X’s resident marine biologist, I figured that I needed to get the dolphin issue out of the way post haste.

It never fails. Every single cocktail party, as soon as someone finds out that I’m a graduate student studying marine biology, they ask, “So, do you get to play with dolphins?” Since my heart is as black and cold as the oceanic abyss, I usually take this opportunity to disillusion yet another poor soul of their childhood fantasy of Mystical Dolphin Love.

Dolphins are not gentle or psychic. If they could talk they would not impart eco-wisdom or deep spiritual truth. Dolphins are violent predators with a predilection for baby killing and rape. I feel it’s my duty to warn you, despite the risk of insulting creatures made of hundreds of pounds of muscle and rows of sharp teeth. Throw out your rainbow dolphin painting, and check out dolphins’ low-down dirty secrets:

Head over to the shiny pretty Double X site for the rest.

Don’t believe my tales of dolphin deeds done dirt cheap? The original peer-reviewed research is listed below. Or check out the lads of Southern Fried Scientist on dolphin worship and the evils of dolphin-safe tuna.

Oh, and you know that whole thing about Double X syndicating the Oyster’s Garter? Well, somehow I got it totally wrong. Most weeks, I’ll be posting at the Double X outpost on Tuesdays and Thursdays. The rest of the time I’ll be comfortably ensconced right here.

“A Sea Change” reviewed; or, HALP! Iz I stuck in the ivory science tower?

May 12, 2009

After seeing “A Sea Change,” a documentary about ocean acidification, I felt really, really guilty. Not because of my carbon footprint, but because I did not like this earnest, passionate movie.

“A Sea Change,” which made its southern California debut at the Scripps Institution of Oceanography last week, is essentially one big appeal to emotion. Everyman Sven Huseby embarks on a quest to save the oceans for his overly adorable grandson, seeking answers in scientific meetings, subarctic labs, and even artist Maya Lin’s studio. The narrative is frequently interspersed with Mr. Huseby writing heartfelt letters to and frolicking with his grandson, as well as multiple scenes on his computer googling away for “pteropods” and “ocean acidification.” Since the filmmakers said that they were determined to avoid graphs, information is conveyed in voiceovers while the audience listens to Phillip Glass music (Battlestar Galactica fans will feel like they’re in the Opera House) and gazes at pretty ocean scenes.

I was bothered by the lack of informative content. I understand that oceanic carbon chemistry and acidification is extremely difficult to explain and understand, but there is almost no mention of what ocean acidification actually is. There was an interesting demonstration of the effects of carbonated soda water on human teeth (they dissolve!), but since soda water is far more acidic than even the worst seawater, will people find this convincing? At another point Mr. Huseby mentions “a world without fish” but we have no idea how this is linked to ocean acidification, except for that it has to do with CO2 somehow.

I did like that the last third of the movie focused on climate change solutions. Mr. Huseby visits Google’s solar panels, a wind farm, and a hotel that runs on ocean geothermic energy. He makes the excellent point that clean energy technology exists! It exists right now! We should use it! I was also shocked and intrigued at a statistic casually bandied about by climate scientist Ken Caldeira. Caldeira said that fixing the climate change problem would cost less than 2% annual GDP. I would love to know more about that figure. Whose GDP? And what does 2% actually mean in terms of predicted economic impact?

As a nascent scientist who took an entire seminar on the scientific ocean acidification literature,  I’m not the target audience for “A Sea Change.” But I’m not sure who their audience might be. In my opinion, the movie is not informative enough to show in science classes, and I don’t know if young people will emotionally connect with a grandfather’s quest. (It doesn’t help that nearly every single person in the movie is white.)  I could see the movie resonating with older, non-scientific audiences, but as a young science person it’s hard for me to tell.

I would love to hear from others who have seen “A Sea Change.” Am I a sterotypical scientist addicted to facts and graphs? A grinch who hates sea lions and blond moppets? Or do non-scientists also want more content from their science documentaries?


Mega Shark Vs. Giant Octopus: The Trailer Released

“The California coast is terrorized by two enormous prehistoric sea creatures as they battle each other for supremacy of the sea.”

[YouTube="http://www.youtube.com/watch?v=Fa7ck5mcd1o"]

Mega Shark Vs. Giant Octopus is an actual film, due out  May 26.

WordPress makes embedding videos from certain sources tricky, so you must click to view the trailer. But click.  Seriously. Do it.

Update: Trailer has been YouTubed. <phew>

Update, Update: As pointed out by commenter below, the movie stars Deborah “Debbie” Gibson. Yes, that Debbie Gibson.

Update, Update, Update: We all know how this movie must end, right?

Yet more vampire ecology

May 10, 2009

The Twilight and Buffy vampire ecology models were not the first to plumb the mysteries of vampire population dynamics – mathematicians and economists got there first. Mark Strauss has a nice writeup of the wrangling in the vampire literature:

But, this gauntlet had been barely thrown down before it invited a rebuttal from mathematician Dino Sejdinovic. In his article, “Mathematics of the Human Vampire Conflict” (Math Horizons, November 2008) Sejdinovic faults Efthimiou and Gandhi’s logic, since they have not “accounted for the birth-rate of non-vampires and death-rate of vampires (actually the death-death-rate since they are already dead, but when they die again they should stay dead but stop being living) due to close encounters with stakes, garlic and holy water.” Moreover, “vampires are presented exclusively as greedy consumers: a rational strategy of managing their human resources is not considered…”

Their research provoked an outraged response from economist Dennis Snower, who in his article “Macroeconomic Policy and the Optimal Destruction of Vampires” (The Journal of Political Economy, June 1982)…Snower argues that the mortal world can manage its resources in a manner that keeps the undead population in check, while simultaneously promoting long-term economic growth.

Strauss points out that all of these models assume that vampires are the top predator. While the Buffyverse model accounts for Slayer predation, clearly the time is ripe an elucidation of the entire supernatural ecosystem. Zombies and werewolves and demons, oh my.


TGIF: The ocean sure is pretty

May 8, 2009

After a week of running around Arizona and another week of utter grad school madness, things should be a bit more regular around here. In the meantime, relax on this lovely Friday with gorgeous underwater photography from the Rosenstiel School of Marine and Atmospheric Science’s 2009 amateur underwater-photography contest, republished by National Geographic. Here’s a few of my favorites.

In which I lose my mind. Also, carnivals!

May 5, 2009

Like unto the great Pacific Ocean, the Oyster’s Garter appears peaceful and empty. Yet it filled with treacherous riptides and unexpected stingrays as I slip ever deeper into the twilight midwater of huge piles of work. Does that analogy even make sense? What with 2 hours of sleep, I can’t tell. BEHOLD THE GLAMOUR OF MARINE BIOLOGY!

While I toil and moil, please enjoy two fine carnivals. Frankly, I haven’t read anything in them, but I’m sure many delights await. The Carnival of the Blue is up at Sea Notes, and the Carnival of Evolution is up at Oh, for the Love of Science!


Opportunity for journalists to play in the ocean

May 5, 2009

I’m back and digging out from vasty piles of email and work. In the meantime, check out this supercool opportunity from Woods Hole. It’s a fellowship for journalists and communicators to learn about ocean science:

Through seminars, laboratory visits, and brief field expeditions, Ocean Science Journalism Fellows gain access to new research findings and to fundamental background information in engineering, marine biology, engineering, geology and geophysics, marine chemistry and geochemistry, and physical oceanography. Topics range from harmful algal blooms to deep-sea hydrothermal vents; from seafloor earthquakes to ice-sheet dynamics; from the ocean’s role in climate change to the human impact on fisheries and coastline change; from ocean instruments and observatories to underwater robots.

Thanks, Talina!
