Split the Difference: Applied vs. Basic Science

Dr. David Kimbro FSU Coastal & Marine Lab
Looking over the catch

Shannon Hartsfield and Colonel Donald Jackson of the Army Corps of Engineers South Atlantic Division look over their catch during an oystering demonstration at Cat Point Bar. This demonstration was meant to show the problems caused by low fresh water input into the bay. Below, David talks about starting to work towards a possible solution.

Spread offense or Power-I formation? Man-to-Man or Zone defense? Austerity or Stimulus spending? And most importantly, Batman or Batgirl?

Whether leading a team of athletes or a population of countrymen, deciders frequently confront such either-or decisions or binary outcomes (i.e., yes or no).

Because time is one of our most limiting resources, natural scientists confront such a dilemma right out of the gate: should I pursue Applied or Basic scientific research?

By applied, I mean research that focuses on immediate solutions to societal problems: How can we deal with a new infectious disease (e.g., avian flu)? Where did the BP oil go?

By basic, I mean research that focuses on improving our knowledge about the nuances of the natural world: How many galaxies are there in the observable universe and how were they formed (I just saw a must-see iMax movie, Hubble 3D, at the JFK Space Center Visitor Complex)? Why is biodiversity so much greater in the tropics?

Flashing back to my childhood hero, I realize that Michael Jordan will likely remain the best basketball player to ever play not solely because of his offense (which was certainly top tier), but also because he worked relentlessly to become a top-tier defender as well. Obviously, few people can master both sides of a spectrum, and sometimes a focus on both or on splitting the difference can come with great cost. For example, my favorite college football team (UNC) is implementing a hybrid defense (i.e., a 4-2-5 instead of a 4-3 or a 3-4) this year; we LOST 68-50 this last Saturday…in FOOTBALL!

Because my plans for playing in the NBA and NFL obviously aren’t working out, let’s get back to science and the merits of focusing on both ends of the science spectrum.

Recently, I talked about this topic with a leading research and clinical Psychologist at Florida State University, Dr. Thomas Joiner. Ignorantly, I thought FSU was only great in Football…turns out that they also have the best Psychology department in the nation. In a recent book Lonely at the Top, Dr. Joiner weaved together many interesting and Basic research studies to show how gender and evolutionary forces cause nuanced interactions all the way from neurons and one’s health to one’s social behavior. It was fascinating to learn how these interactions can promote the loneliness that facilitates suicides.

But while all of these powerful connections lined up well for the main argument of his book, I am equally interested by a conversation we recently shared together about there being many applied problems that can’t wait around for further testing of nuanced ideas. For instance, Dr. Joiner recently began working with the US military to study and reduce the causes of suicide within the military. As Dr. Joiner indicated, the military probably couldn’t give a darn about Basic research findings. They just want some realistic solutions and they want them yesterday.

If you stuck it out this far, you are probably wondering, “how does this relate to oysters, predators, etc.?” Well, the motivation of my Basic research is to increase our knowledge about how predators keep the lights on for many of the natural systems that we depend on like oyster reefs, salt marshes and seagrass beds. But in pursuing this research over the past three years, I have confronted a very important applied problem that needs immediate solutions: the oyster fishery of Apalachicola, Florida presently contains too few oysters to support the local economy (Download a PDF of the Department of Agriculture and Consumer Services report here).

So, if you follow this blog, you’ll get to see whether my attempt to be like Mike (if you’ve seen my vertical leap, it’s obvious we’re talking research and not b-ball), to emulate the approach of Dr. Joiner, and to split the Applied–Basic difference is a success or a bust. I’ll be working with a lot of good researchers (Florida Sea Grant, UF Oyster Recovery Task Force), state organizations – Florida Department of Agriculture & Consumer Services (FDACS) and Florida Fish & Wildlife Conservation Commission (FWC)- and the local community to examine the following:

David accompanies FDACS on a sampling trip in Apalachicola Bay as part of a new collaboration.

(1) How in the heck do you work in such a large and logistically challenging system?

(2) What is the extent of the problem…how far gone is the resource?

(3) After getting some research under our belts, what our some realistic options to this problem?

(4) Because we all want answers to these questions yesterday, can we explore the existing data, which was impressively collected by FDACS for the past 30 years, to get a head start?

Finally, I suspect that this Applied perspective may help inform the merits of my Basic interests. There are a ton of things that could be contributing to the failure of the oyster fishery such as climate change, drought, fresh-water extraction, over-harvesting, disease, nutrient inputs, and water quality. Whether or not any of our predator ideas help explain the lost of this fishery represents a very big test. In other words, relative to other explanations, is all of this predator stuff really important?

Ok, as the locals along the Forgotten Coast say “let’s get’er done”.

Best,
David

Take the RiverTrek 2012 photo tour down the Apalachicola River. You can zoom in and scroll across the map for greater detail. Later we’ll post a map with more of the basin and bay as well, from our other EcoAdventures in the area (River Styx, Graham Creek, etc.). Also, many of the locations are approximate. We did not geotag the location of every houseboat on the river, but the photos do show up in the same general vicinity (with the exception of more recognized landmarks such as Sand Mountain, Alum Bluff, etc.).

The River, the Bay, and the Army Corps of Engineers

Slideshow: Army Corps of Engineers visit Apalachicola Bay

Tonight on WFSU’s Dimensions: Part 1 of the RiverTrek 2012 Adventure.  Days one and two of paddling, camping, hiking and climbing air at 7:30 PM/ ET with an encore on Sunday, October 28 at 10 AM/ ET.  The trip concludes with Part 2 (Days 3-5) on Wednesday, November 14 at 7:30 PM/ET.

The slideshow above was photographed on Monday, when Army Corps of Engineers colonels were invited (along with state agency officials and media) to see firsthand how depleted the oyster reefs in Apalachicola Bay have become.  We went out in three oyster boats, captained by the leadership of the Franklin County Seafood Workers Association, to the Cat Point bar.  Cat Point is usually one of the most productive winter reefs in the bay.  In early September, the Summer reefs closer to the mouth of the river are closed and the Winter reefs further out are opened up.  The Winter reefs should have spent months replenishing and younger oysters should have matured into legal sized, commercially viable oysters.  Only this year, it didn’t happen.

Colonel Donald Jackson receives oystering tips from Shannon Hartsfield.

Shannon Hartsfield, President of the Association, takes a few licks with his oyster tongs and then hands the them to Colonel Donald Jackson.  Colonel Jackson takes a few licks; between the two of them they take about eight.  Hartsfield inspects their catch: about six legal oysters in a pile of dead shell. Later he tells me that in past years, that amount of work would have yielded about a 30 lb. bag of legal oysters.  This is what the Army Corps of Engineers colonels were invited to see.  The Corps controls the flow of water in the Apalachicola/ Flint/ Chattahoochee basin, directing water into over 200 reservoirs and adjusting how much flows through dams.  The lack of water flowing from the Apalachicola River, due in large part to the drought we’ve experienced over the last couple of years, is the main cause of the fishery crisis.  The oystering demonstration is the Franklin County Seafood Workers’ argument for more water to be allowed through Woodruff Dam at the Florida/ Georgia border.

The wrangling over this water is often portrayed as between seafood workers in the bay and Georgia’s farmers and Atlanta’s water consumers.  But the list of stakeholders also contains power companies (hydroelectric and nuclear), MillerCoors LLC, manufacturers, and recreational concerns, to name a few (see the full list here).  It’s messy.  And change doesn’t look like it’s coming soon.  As the colonels said during the community meeting later that night at the Apalachicola National Estuarine Research Reserve, they are soldiers following a protocol.  A new protocol (an update to the ACF Master Water Control Manual) is being drawn up, but changes will not take effect for 2-3 years, and in the meantime there isn’t a lot of leeway for how the water can be redirected, at least not by the Army Corps of Engineers’ authority (The U.S. Legislature grants them the authority they have). They are taking public input for the Manual Update, you can send your comments here.

This slide provided by Helen Light (©USGS) illustrates the floodplain supported by the river. As water levels have decreased over the last few decades, there has been a loss of 4 million trees in the floodplain and a loss of aquatic habitat.

During that meeting, presenters from different agencies, universities, and local concerns laid out the impact of the low water flow on the bay and on the river basin.  The next day, the colonels would be going up the river to see the effects of low flow there, where I had just paddled a week-and-a-half ago in the video that airs tonight.  My interest had been, as a main focus of the In the Grass, On the Reef project is oyster reef ecology, the bay and how the lack of river flow had affected it.  As Helen Light said to us on the first night of the trek “You all know a lot about the bay, and the impacts in the bay, you’ve been reading it in the paper.”  That night, gathered around her on the sand bar across from Alum Bluff, she proceeded to tell us about the effects on the river.  She had studied the floodplain for decades while working for the US Geological Survey, and has seen the changes undergone as river flow has decreased over the last few decades.  I keep going back to her talk in the video, much as we did in our conversations kayaking down the river.  Even as we were falling in love with the river (or reconnecting with it), we learned of its struggles and the troubles it was facing.

For all of the statistics on the decline of the river, it was still a beautiful paddle.  The fish were jumping, eagles soared overhead, turtles sat on logs- and as we reported, there were plenty of snakes.  We got off the river, too, to see some of the creeks, swamps, and forest around it.  For all its troubles, the river is still enjoyable, as are its products.  There has been a 44% decline in Ogeechee Tupelo trees along the river since 1976, but you can still buy tupelo honey produced from the trees in the river basin.  And at the reception after the community meeting on Monday, the same day I saw oystermen pull dead shell off the floor of the bay,  there were trays of healthy looking Apalachicola oysters on the half shell.  As tourists and consumers, it can be easy to dismiss the stats when our own eyes (and taste buds) tell us everything looks normal.

The making of an experiment

Dr. Randall Hughes FSU Coastal & Marine Lab

“Wow, quite the set-up! I am jealous of that space!

“…As a side question, how did you pump the cue water to all your tubs, a peristaltic pump? Was it just gravity? Seems like quite the complicated set-up.”

Excerpts from a comment on Randall’s September 28th post, Scared Hungry.  Read the whole comment here.

IGOR chip- employment 150This recent comment by John Carroll made me realize that there are a lot of unsung heroes at the lab that don’t typically get credit for the essential work that they do to facilitate our research. So here is a ‘behind-the-scenes’ look at setting up an experiment:

1. The idea. This is the main part that I can take credit for, though even then an idea usually stems not simply from my brain, but from a paper I’ve read, a conversation with a colleague or student, or an observation in the field.

2. The infrastructure. Each experiment has its own specifics, but in my research there are generally 3 main requirements:

DSC_0227

The "small" deck, used by David and me for mesocosm experiments with snails, crabs, plants, oysters - you name it!

a. Space. FSUCML has numerous tanks and related facilities for use in research (Visit the Lab site here.). Of course, I often have specific needs or desires, and thus my first step is usually to speak to Mary Balthrop, our Associate Director, and then to Dennis Tinsley, our Facilities Manager. Both Mary and Dennis show a great deal of good humor in receiving my seemingly hair-brained requests (e.g., a deck that can hold 16 plastic kiddie pools full of sand and water!), and they work with me to find (or devise) a suitable space to get the job done. Our incredible carpenter, Dan Overlin, then has the task of modifying or creating that space.

b. Seawater. Since we work with marine critters, access to seawater is critical. FSUCML pumps seawater from the bay in front of the lab into large holding tanks that feed the entire facility.

Mark Daniels and Bobby Henderson then create the plumbing system that gets that water where it needs to go. They know everything there is to know about PVC pipes, water filters, pumps – you name it! As I mentioned in my response to John, it was Bobby who came up with the incredible pump apparatus (and several subsequent revisions) that has enabled us to conduct several experiments examining the effects of predator cues on prey behavior.

c. Light. When working with plants, light is key. I’m fortunate to have access to a greenhouse, as well as abundant outdoor space at the lab to set up experiments. Or perhaps I should say once-abundant outdoor space, since David and my decks now cover a good chunk of it! Dennis is a pro at thinking of suitable and available spaces to squeeze in a few tanks.

3. The supplies. Once the infrastructure is in place, it’s time to buy the supplies needed to make each experimental unit. The job then falls to Kathy Houck and Maranda Marxsen to explain to the accountants at FSU why I purchased several large bolts of tulle fabric (grasshopper cages), or 24 pair of knee-high panty hose (they make great filters when filled with gravel), or lots and lots of nail polish (for marking snails). For field experiments, Sharon Thoman is helpful in arranging vehicles and boat reservations, sometimes at the very last minute!

A thundercloud looms in the distance. Once this summer we were stranded in a storm and Dan came to retrieve us.

4. Set-up. Once things start to come together, there are inevitable surprises the crop up. In our recent predator-prey experiments, we had issues with flow from the pump being greater than that from the regular seawater lines, which required some brain-storming from Bobby, David, Kelly, Meagan, and myself. Or, a plumbing line will clog, and I’ll run to find Mark.  Or, we’ll get stranded in a thunderstorm while collecting mud crabs and Dan will come pick us up.   At least we often provide fodder for funny stories!

5. The experiment. And at last, the actual experiment can begin. When I come up with particularly high-maintenance experiments, it’s useful to utilize the lab dorms for the night. Linda Messer is always understanding of last minute housing requests and changes, making sure the lights (and, more importantly, the A/C) are on! Sometimes, the experiment itself is much shorter than the time required to set it up – duration never seems to equate with complexity. But one of the benefits of consulting with the staff is to ensure that the same space can be used for multiple purposes. And the second experiment is always easier to set up than the first!

Summer Chaos and The Tower of Cards

Throughout this week, Dr. David Kimbro has been updating us about the premature dismantling of his lab’s summer experiment in preparation for Hurricane Irene.   Before this turn of events, David’s lab tech, Tanya Rogers, had written this account detailing how much work went into assembling the experiment and all of its (literally) moving parts.

Beautiful, isn't it? But working on oyster reefs in Jacksonville hasn't been as nice as its sunrises.

For many labs, the summer field season is a period of intensity and madness: a time for tackling far too many projects and cramming as much research as possible into a preciously short window. It’s a demanding flurry of activity occasionally bordering on chaos. The greatest challenge for technicians like myself is to maintain order in this pandemonium of science, and to carry out as much field work as efficiently as possible without going crazy.
