Join the UF/IFAS Natural Resource Extension Agents as we explore the Navarre Beach Marine Sanctuary.
Thursday, August 17, 2017 from 9 am until 1 pm.
Register today at: https://nbsnorkel.eventbrite.com
The Navarre Beach Marine Sanctuary consists of 30 reef structures in the Gulf of Mexico. The whole site is as large as a football field. Reefs are located in 6 to 15 feet of water.
Participants will enjoy a brief introduction about the history of the reefs and economic impacts for the community. We will then head out to snorkel the reefs and observe the wildlife that can found in the area.
Participants will be expected to swim at least 375 feet to access the site and be experienced swimmers/snorkelers. Participants may see marine life such as: sea turtles, octopi and many fish species that inhabit the reef. Participants will need to bring a mask, snorkel and fins, flotation device such as a boogie board or a buoyancy compensator vest, sunscreen, etc. Cost is $20.00, lunch is included.
We will meet at the Sea Oat Pavilion which is at the second Gulf side parking lot in the NB Marine Park. There are picnic tables, restrooms, changing area and shower at the Pavilion.
This adventure is weather dependent, refunds (minus the Eventbrite fee) will be provided if we have to cancel due to inclement weather conditions or poor water visibility. If you have questions, please contact Chris Verlinde, 850-623-3868 or email@example.com.

Summer is a great time for weather-watching in the Florida panhandle. Powerful thunderstorms appear out of nowhere, and can pour inches of rain in an area in a single afternoon. Our bridges, bluffs, and coastline allow us to watch them develop from a distance. Yet as they come closer, it is important to recognize the potential danger they pose—lightning from these storms can strike anywhere nearby, and can cause fatality for a person who is struck. Nine people were killed by lightning strike in Florida in 2016 alone, more than in any other state. Because of the risk posed by lightning, my family and I enjoy these storms up-close from indoors.

A fraction of the rain that falls during these storms is delivered to our bays, bayous, and estuaries through a drainage network of creeks and rivers. This streamflow serves several important ecological functions, including preventing vegetation encroachment and maintaining habitat features for fish and amphibians through scouring the streambed. High flows also deposit fine sediment on the floodplain, helping to replenish nutrients to floodplain soil. On average, only about one-third of the water that falls as rain (on average, more than 60 inches per year!) turns into streamflow. The rest may either infiltrate soil and percolate into groundwater; or be consumed and transpired by plants; or evaporate off vegetation, from the soil, or the ground surface before reaching the soil. Evaporation and transpiration play an especially large role in the water cycle during summer: on average, most of the rain that falls in the Panhandle occurs during summer, but most stream discharge occurs during winter.
The water that flows in streams carries with it many substances that accumulate in the landscape. These substances—which include pollutants we commonly think of, such as excessive nutrients comprised of nitrogen and phosphorus, as well as silt, oil, grease, bacteria, and trash—are especially abundant when streamflow is high, typically during and following storm events. Oil, grease, bacteria, and trash are especially common in urban areas. The United States EPA and Florida Department of Environmental Protection have listed parts of the Choctawhatchee, St. Andrew, Perdido, and Pensacola Bays as impaired for nutrients and coliform bacteria. Pollution issues are not exclusive to the Panhandle: some states (such as Maryland and California) have even developed regulatory guidelines in streams (TMDLs) for trash!
Many local and grassroots organizations are taking the lead on efforts to reduce pollution. Some municipalities have recently publicized efforts to enforce laws on picking up pet waste, which is considered a potential source of coliform bacteria in some places. Some conservation groups in the panhandle organize stream debris pick-up days from local streams, and others organize volunteer citizens to monitor water quality in streams and the bays where they discharge. Together, these efforts can help to keep track of pollution levels, demonstrate whether restoration efforts have improved water quality, and maintain healthy beaches and waterways we rely on and value in the Florida Panhandle.

Bacopa caroliniana, also known as lemon bacopa, is a popular aquatic plant. It is mostly found in the southeastern United States in states such as Florida, Alabama, Georgia, South Carolina, Mississippi and even Texas. Lemon bacopa has a perennial life cycle that could make it a weed to some, or desired plant to others. Also, it can be found as a submergent plant or an emergent one.
It tends to grow near shorelines and sometimes in water that is less than 3 inches deep. Lemon bacopa has a single stem with opposite leaf growth. The leaves are thick and juicy. The reason some people enjoy and even encourage planting this plant is the pretty, attractive, purple-blue flower that sprouts. They are a popular plant used to add beauty to water gardens and to provide habitat in wetland enhancement as well as restoration projects. However, this plant can be easily propagated which could lead to it becoming weedy if not paid attention to carefully. Lemon bacopa roots easily from cuttings, so whether if it is purposely cut or by natural causes, it can easily spread and take over a water garden.
This species is very adapted and common throughout Florida. Although lemon bacopa can be weedy in some situations, it is most often considered a beneficial native plant that brings a number of desirable characteristics to almost any aquatic setting.

Climate change is one of those topics that most people don’t want to think much about. It can be overwhelming, it can be controversial, and it can be downright frightening. A year ago, Yale and George Mason University completed the most recent surveys in the “Six Americas” study, which determined levels of belief and concern in global warming. The “Six Americas” range from people who are alarmed, concerned, cautious, disengaged, doubtful, or dismissive when asked about climate change. Interestingly enough, 34% of Americans consider themselves concerned while 23% were cautious. Ranking third were 11% who are doubtful about climate change.
When you start to drill down into the individual questions asked on the survey, you see more agreement. For example, when Escambia County citizens were asked whether global warming is caused by human activities, somewhere between 45%-50% said yes. However, when asked whether they think global warming is actually happening (regardless of cause), the percentage went up to 65%-70%. When asked if they support funding research into renewable energy sources, Escambia County residents jumped up to an 80%-85% agreement. That, to me, is nothing short of a miracle, having lived in Escambia County long enough to know there’s rarely that much agreement on anything!
The takeaway message from that survey, to me, is that regardless of where people stand on climate change/global warming, there are some starting points that can be common ground. If the majority of a community believe climate change is happening and that supporting renewable energy research is a good thing, then they can work towards those outcomes to the mutual benefit of all.
An example of one small but significant step towards sustainable energy use includes bicycle share/rental facilities. On a recent trip to Salt Lake City, solar-powered bike stations were strategically placed around the downtown area. For a small fee, the bicycles could be checked out (for 30 minutes at a time) up to 24 hours. This ensures there are plenty of bicycles available for other users, and stations are close enough to one another that it’s easy to check bikes in and out if you need more time. The benefits of encouraging bicycles are numerous; reduced traffic and burning of fossil fuels, reduced need for parking in high-value real estate, and health benefits for riders. The other investment necessary to make biking more prevalent and successful are bike lanes, which were plentiful in Salt Lake City to keep riders and drivers safe. Once safe bike lanes are in place, those who live in the area with their own bikes are more likely to use them on a regular basis, further decreasing vehicular traffic.
There are many great organizations and publications around the country dedicated to increasing bicycle use and safety. For more information, check out Trail Link, Momentum Magazine, or the Burlington Bikeway.
The St Andrew Bay pass jetty is more like a close family friend than a collection of granite boulders. The rocks protect the inlet ensuring the vital connections of commerce and recreation. One of the treasured spots along the jetty is known locally as the “kiddie pool”, which is accessible from St Andrew’s State Park. There are similar snorkeling opportunities throughout northwest Florida. Jetties provide an opportunity to explore hard substrate or rocky marine ecosystems. These rocks are home to a variety of colorful sub-tropical and migrating tropical fish.

Exploring a jetty is more like a sea-safari adventure than an experience in a real swimming pool – it is a natural place full of potential challenges that first time visitors need to prepare to encounter.
Divers and snorkelers are required to carry dive flags when venturing beyond designated swimming areas. These flags notify boaters that people are in the water. Brightly colored snorkel vests are not only good safety gear but they help you rest in the water without standing on rocks which are covered in barnacles and sometimes spiny sea urchins.
According to the Florida Department of Health, most sea urchin species are not toxic but some Florida species like the Long Spined Sea Urchin have sharp spines can cause puncture injuries and have venom that can cause some stinging. Swim and step carefully when snorkeling as they usually are attached to rocks, both on the bottom and along jetty ledges. Photo by L Scott Jackson
Dive booties also help protect your feet. I found out the hard way! A couple of years ago my foot hit against a sea urchin puncturing my heel. The open back of my dive fin did not provide any protection resulting in a trip to the urgent care doctor. My daughter later teased it was an “urchin care” doctor! Sea urchin spines are brittle and difficult to remove, even for a doctor. Lesson Learned: “Prevention is the best medicine”.
After a couple of weeks of limping around and a course of antibiotics, I recovered ready to return one of my favorite watery places – a little wiser and more prepared. I now bring a small first aid kit, just in-case, to help take care of small scrapes, cuts, and other minor injuries.
Gloves are recommended to protect hands from barnacle cuts and scrapes. Shirts like a surfing rash guard or those made from soft material help keep your body temperature warm on long snorkel excursions. Along with sunscreen, shirts also protect against sunburn.
There’s opportunity to see marine life from the time you enter the water with depths for beginning snorkelers at just a few feet deep. Some SCUBA divers also use the jetty for their initial training. Most underwater explorers are instantly hooked, and return for many years to come. Photo by L Scott Jackson
Finally, know the swimming abilities of yourself and your guests, especially when venturing to deeper areas. It’s good to have a dive buddy even when snorkeling. Pair up and watch out for each other. Be aware that currents and seas can change dramatically during the day. Know and obey the flag system. Double Red Flag means no entry into the water. Purple flags indicate presence of dangerous marine life like jellyfish, rays, and rarely even sharks. Local lifeguards and other beach authorities can provide specific details and up to date safety information.
