What Have Seagrasses Done For Me Lately?

Episode 6: Blue Carbon Where the Stingray Meets the Horse Conch

At the beginning of September, Randall and David had a visit from Dr. Peter Macreadie of the University of Technology, Sydney.  In this video, Randall takes Dr. Macreadie for a snorkel in St. Joseph Bay.

We now focus our attention to seagrasses, which as it turns out, often don’t get a lot of attention, at least in comparison to other marine habitats like coral reefs or even salt marshes.

In part, this lack of attention is due to the fact that seagrasses typically live completely underwater, except at very low tide, and so they are not as noticeable as marshes are. In addition, seagrasses often occur in shallow estuaries not known for their great visibility (and thus not as ideal a location as coral reefs for snorkelers or scuba divers). And, although I disagree, some people just don’t find them very pretty.

Last week as I was starting to think about this post, there was a small uptick in the number of media articles related to seagrasses, at least in Australia. The increased interest was in response to a proposal by the Environment Minister, Tony Burke, to require greater seagrass protection from mining and development projects (read more in this article from the Brisbane Times). As justification for the increased financial burden on companies, Mr. Burke cited the many benefits that seagrasses provide. And just what are those?

Scallop in St. Joseph BaySeagrasses (like salt marshes and oyster reefs) provide habitat for many, many fishes and invertebrates. Studies have found that the number of animals living in seagrasses beds can be an order of magnitude higher than the number living in adjacent coastal habitats. Many of these animals rely on the seagrass beds as a “nursery” that protects them from predators until they grow larger. And lots are recreationally and commercially important species that we like to eat. (Scallops, anyone?)

Seagrasses are also incredibly productive plants, sometimes growing more than 1cm per day, and rivaling our most productive crop species like corn. Because a significant portion of this plant material (particularly the roots and rhizomes below ground) stays in place once the plants die, seagrasses can also serve as important ‘carbon sinks’, or buried reservoirs of carbon. In fact, a recent study estimates that the carbon stored in the sediments of seagrass beds is on par with that stored in the sediments of forests on land!

Although lots of the productivity of seagrass beds makes its way underground, some of it does get eaten. Major consumers of seagrasses include urchins and fishes, as well as the more charismatic dugongs, manatees, and sea turtles.

Spider Crab in St. Joe BaySeagrasses (like salt marshes) also play an important role in reducing nutrients that run off from land into the water. Unfortunately, these nutrients can also lead to the loss of seagrasses, by promoting increased growth of algal “epiphytes” that grow on the blades of the seagrasses themselves. When there are not enough small fishes and invertebrates around to eat these algae, they can overgrow and outcompete the seagrass, leading to its decline. And when the seagrasses become less abundant, the animals that rely on them are also often in danger.

The Big Bend and Panhandle of Florida are home to expansive seagrass beds that also often go unnoticed. But they contribute to the productivity, diversity, and beauty of this area in many ways, as anyone who has been scalloping recently has surely realized!

SciGirls Tallahassee (and Rebecca) Cope with Marsh Mud

Episode 3: Studying Nature Involves Visiting and Standing in Nature

In a couple of weeks we’ll dive right in and look at oyster reefs and their surprising value. In the weeks following, we’ll do the same with salt marshes, seagrass beds, and with the unique diversity of Bay Mouth Bar.  Right now, we hope you enjoy watching the WFSU/ Mag Lab SciGirls get their footing in the intertidal zone.

SciGirls' mudy feetThe first question I was asked when I became involved in the In the Grass, On the Reef project was if I was afraid to go out in the field and get a little dirty. “Of course not!” was my response. I have always been a fan of the outdoors and love scalloping and kayaking, so of course I would love this. I guess I was expecting to be in the water more than anything. After all, we couldn’t really be going out into anything too messy, right?

The first few shoots I went on were great and went about how I expected they would. But after a few weeks we went to Wakulla Beach, where I discovered exactly why I was asked that particular question when I was hired. Not fully prepared for my experience that day, I had quite a time trying to walk through the mud without getting sucked in knee-deep and losing my shoes, causing others to slow down and get stuck as well while they were trying to help me out. After clawing my way out and finally escaping the mud, I walked on an oyster reef for the first time. While the mud was not nearly as bad at this point, I am a terribly clumsy person. Luckily, I was able to keep my footing and avoid falling on top of oyster shells.

Although it was exhausting, I still enjoyed my Wakulla Beach experience, as I’ve come to call it. It was definitely a learning experience for me and I loved being able to see the sunset over the reefs. I have yet to master the “quick, light steps” needed to defeat the mud, but I definitely have an appreciation for what our scientists, and many others, go through to set up experiments and collect their data. I also love that getting out in the water (and mud) are a part of my job, not to mention that we get to see some really cool things. Every shoot is a new experience and I notice more about the environment and the animals each time I go out.

And Also, the Animal Experience

Rob Diaz de Villegas WFSU-TV

Animals with claws suited to tearing through oyster shell can, unsurprisingly, injure you.

One thing we didn’t mention in the video above or in Rebecca’s post are the animals at the sites, which you definitely have to keep an eye out for.  Members of the Hughes and Kimbro labs have been pinched by blue crabs and have encountered the occasional snake in the marsh.  There are small sharks, the possibility of alligators, and the sting rays that we see and shuffle our feet to avoid stepping on and startling.  You keep an eye out for those knowing that they’re a potential danger, though not a pressing threat.  During last week’s shoots in Saint Augustine, however, events in the news had us paying serious attention to the smallest animals that are also the ones that attack us most relentlessly.  Our country is in the midst of perhaps its worst ever outbreak of West Nile virus.  Mosquitos are a fact of the coast.  During the day, there is usually enough of a breeze to keep them off you; but since the work we follow is tidally based, activities can occur before sunrise or after sunset, when mosquitos are at their worst.  Alligators may look scarier, but it pays to know what the most pressing threat is.

Listen to last Thursday’s Talk of the Nation on preventing West Nile.

WFSU SciGirls “In the Grass,” Talking Science

Episode 2: Talkin’ Science

In September we’ll tour our coastal ecosystems and learn why we love them.  These next couple of weeks, we’ll get a fresh set of eyes on Randall and David’s world of research and ecology as the WFSU/ Mag Lab SciGirls visit the FSU Coastal and Marine Lab.

Dr. Randall Hughes FSU Coastal & Marine Lab

Randall explains experiment to SciGirlsWhen you think of your summer vacations during middle school, what do you think of? The first thing that comes to my mind is HOT (it was south Georgia, after all), and the next thing is Duke. I realize that is somewhat sacrilegious for someone who went to UNC-Chapel Hill for undergrad (at least if you care anything about basketball). But I spent 4 summers as a student at the Duke University Talent Identification Program, better known as TIP, and my 3 weeks spent there each summer definitely stand out in my mind.

It sounds horrible to most people – 3 weeks during summer vacation spent taking an intensive course that would typically last a semester. Although we spent a lot of time in class and studying, in many ways it was like any other summer camp, with time spent goofing off with really interesting and fun classmates from all over the country. I even crossed paths with some of my fellow TIPsters in graduate school!

SciGirls trek into the marshSo what does this have to do with In the Grass, On the Reef? In many ways, nothing. But in some ways, everything. Because one of those summers I took Marine Biology at the Duke University Marine Lab in Beaufort, NC, and it was there that I fell in love with doing research on coastal systems (and did my first experiment on fiddler crabs!). Admittedly, it still took me a while to figure out how to turn that into a career, but I’m not sure that I would be where I am today were it not for 3 weeks during the summer before 8th grade.

Enter the SciGirls. For the last 4 summers, I’ve been thrilled to participate in the SciGirls summer camp run by WFSU and the National High Magnet Field Laboratory (aka, the Mag Lab), aimed at introducing middle and high school girls to careers in science. Although the SciGirls program is structured differently from the TIP program that I participated in, it provides me an opportunity to share my love of field research with some really amazing girls, and hopefully to plant the seed in their minds that they can turn their love of science into a career too.

This year, in addition to explaining my research to the SciGirls and getting their help collecting data, we talked about the importance of being able to communicate what you’re doing to others. It turns out that explaining research to non-scientists is not something that scientists are trained to do, and it doesn’t always come easy.  So we decided to start early with the SciGirls and see what happens!   As you can see from the video, they quickly grasped what they needed to do and were quite comfortable with the camera. There were some discrepancies among the observations, but hey, that’s why we take lots of data – you can’t always see the overall pattern when you’re only looking at a subset of the information!

The circle is complete. Randall was once the middle school student being led into a marsh for the first time, she is now the one leading middle school girls in. Might this fiddler crab have inspired someone into a career in research?

After a lunch break and a look at the results of our data collection, we headed to the field. This part of the day is always my favorite – watching the girls explore, answering their excited questions, helping them pick up their first fiddler crab, assuring them their shoes / clothes will come clean.  Even a short rainstorm didn’t dampen their enthusiasm. I would venture a guess that when these girls look back on their middle school summer vacation, their memories of SciGirls will be front and center.

For more on the SciGirls’ day at FSUCML, check out their blog.  And check back next week for video of their experiences in the grass (and mud)!

Video: Where the Land Meets the Sea

Episode 1: Where the Land Meets the Sea

Rob Diaz de Villegas WFSU-TV

This time around, everything is both familiar yet new.

On the new tiles, spat are glued on with a mixture used to repair boat hulls.

I recently went to Saint Augustine to document the second version of Dr. David Kimbro and Dr. Randall Hughes’ tile experiment.  The basic concept is this: attach a certain amount of oyster spat (larval oysters- basically little blobs in the process of growing and building shells) to tiles, leave them on or by oyster reefs and see how they grow, or if they are eaten.  I’ll let Randall and David explain the intricacies of the experiment when we post those videos in January.  Or, you could watch our coverage of that first experiment, conducted in the fall of 2010.  Watching that video and then watching our new videos on the experiment, you’ll notice that both the approach to the experiment and to the video coverage have evolved.  After the Kimbro lab spent so many long days scrambling to collect spat, The 2010 experiment didn’t succeed like they’d hoped.  Likewise, our communication of their research, and the importance of the ecology of intertidal ecosystems, didn’t quite succeed like I had hoped.   I like watching the old videos; I just don’t think they did what we wanted them to.  But you learn, and hopefully, you improve.

This time around, I was struck by how orderly everything was at the Whitney Lab as the oyster crew prepared their tiles.  No more scrambling out at low tide to collect oysters; they had hired someone to breed spat from oysters spanning the Eastern seaboard.  The current tile design and construction had been tested, and would withstand the elements.  Randall and David had learned lessons, and were efficiently implementing their new plan.  But what had I learned?

This attractive gastropod, seen in the video above, is a busycon snail wrapped around an atlantic moon snail that it just happens to be eating. Nature videos have a cast of human, animal, and plant characters.

Early last year, WFSU had a moment equivalent to that of the Hug-Bro labs’ realization that the glue on their initial tiles couldn’t withstand the waves at their sites.  The National Science Foundation had rejected our grant application to fund this project.  After a few months of following their studies and a couple dozen videos, a panel of reviewers let us know everything they thought we did wrong.  That was fun.

When Randall, David, Kim Kelling-Engstrom (WFSU’s Educational Services Director) and I decided to reapply for the grant, we needed a new narrative for what it was that we wanted to communicate.  What was our story?  If you watch our old videos, we’re very narrowly focused on experiments and field work.  There’s a lack of perspective on the impact of the ecosystems on our area, a lack of local color from the excellent locations we visit, and I kind of feel like we could have better captured what a day on a salt marsh or oyster reef was like.  The new application reflected more of the world around the reefs and marshes, and the people who need them.  If you’ve watched the video above, you may have figured that this time, our application was successful.

The red snapper being held by Ike Thomas, owner of My Way Seafood, was caught in 150 feet of water. Before reaching market size, younger snapper are one of many fish species that forage on oyster reefs.

I’m finding the new videos are more fun to put together.  We’re exploring the area more, talking to more people, and it’s easier to spot the animals we care about and get footage of them.  And with funding we have some extra staff helping on the blog and on shoots (like new associate producer Rebecca Wilkerson).  The upcoming videos are like the new tiles sitting in their cages off of Saint Augustine oyster reefs: they are the product of some hard won knowledge.  That experiment ends soon and they’ll see if they get the data they needed to meet their larger goals.  We, on the other hand, are just getting started, and we hope that you’ll keep joining us as we explore that area where the land meets the sea.

Over the next couple of weeks, we see the WFSU SciGirls visit the FSU Coastal & Marine Lab to learn about what Randall does: in the marsh, at the lab, and in front of the camera.  It gets a little messy.  In September, we go in the field with Randall and David onto oyster reefs and into seagrass beds and salt marshes.

Coastal Roundup July 6th – July 13th, 2012

Welcome to our first Coastal Roundup. Every Friday, we’ll post a combination of local events and links to interesting articles relating to coastal ecology, fishing/ seafood, and tourism- basically everything relating to the ecosystems we cover (salt marsh, oyster reef, and seagrass bed).  Leave a comment below if you’d like us to include your upcoming events.

Rebecca Wilkerson & Rob Diaz de Villegas WFSU-TV

Back in the Grass and on the Reefs

We’re back in full production on new videos that explore our coasts and the coastal way of life through the habitats that feed and employ so many in our area.  The slideshow below takes you through the last couple of weeks as we got wet and muddy with Dr. Randall Hughes and Dr. David Kimbro.

Saltwater Fishing

Bay Scallop in St. Joe BayWe’ve been heading back to St. Joe Bay to cover Randall Hughes’ marsh and seagrass bed studies, and this week we’ve been noticing a lot of people out on the water filling their buckets with scallops.  Bay Scallop Season started July 1, and has just been extended by two weeks to close on September 25th. For more information on licensing and catch limits, visit the Florida Fish and Wildlife page on scallop season.

To top off your day of scalloping with a quick and delicious meal, try Bay Scallop Scampi paired perfectly with a crusty bread or steamed veggies.

Red snapperRed Snapper Season has been extended six days in the Gulf of  Mexico. Due to bad weather in June and loss of fishing opportunities, the NOAA Fisheries decided to extend the last day of harvest until July 16th. For more information, including the recent changes, read the full Florida Fish and Wildlife update on Red Snapper Season. (photo copyright Florida Fish and Wildlife Conservation Commission)

While the red snapper has been extended, Snook Season in the Gulf of Mexico will remain closed for another year and is now expected to reopen September 1, 2013.  However, catch-and-release of snook will be allowed during the closure with proper technique, and the Atlantic season will remain unchanged. To learn more about the closure or the proper catch-and-release technique, read Florida Fish and Wildlife’s news release.

Oyster News

Oyster reef, Alligator HarborWe first met Alicia Brown just after her arrival at the FSU Coastal and Marine Lab, when she helped Dr. David Kimbro with his October 2010 “Oyster Push” experiment. Alicia, along with Dr. Laura Petes and fellow grad student Carley Knight, have published a paper in the journal Ecology and Evolution.  The study looks at how low freshwater input affects the survival of the Apalachicola oyster population. Read their full paper here.

Tropical Storm Debby

Shorebirds gather in Tower Pool.Many of us are still drying off from Tropical Storm Debby, and while life is getting back to normal, our coastal ecosystems are still dealing with the upheaval of the storm. Those most harshly affected were the animals that make their homes along our shores. Audubon of Florida reports that shorebird nesting areas and colonies were washed away during the storm.

Sea turtle nests were also affected by the storm. Alligator Point has been having a productive nesting season so far, but as The Tallahassee Democrat reports, the storm washed away many nests or left them inundated for days.

P1000151One of our least heralded defenses against the effects of storms are our coastal wetlands.  For instance, one of the services provided by salt marshes is reducing tidal surge during storms.  This Gainesville Sun editorial looks to remind us of the importance of coastal wetlands during weather events.

Whether you’re a visitor or a resident, it is important to know who to contact for information in case of an emergency, such as the recent storm. To view Emergency Management contact information for each county in Florida visit the Florida Disaster page for contact listings.

Clean Beaches

When you visit a beach with your family and friends, you don’t want to worry about dirty water.  NPR’s health blog reports on ratings released by the Natural Resources Defense Council on the cleanliness of beaches nationwide.  Florida did not boast any 5-star ratings, though our own St. George Island did receive a 4-star rating.
