FaviconUsing the Power of Nature to Fight the Effects of Sea Level Rise 18 Jun 2018, 1:52 pm

South Florida is blessed with water. With an ocean to its east and south and the largest freshwater wetland in North America located to the west, it’s a veritable aquatic paradise. Come rainy season, water comes from the skies as well, with our frequent rains providing ample water for drinking, irrigation and aquatic activities.

But too much of it, particularly from the ocean, can stress our coastal integrity and threaten our very existence. Florida has more residents at risk from the consequences of climate change than any other U.S. state. Globally, South Florida faces the highest risk from the effects of sea level rise in terms of the potential loss of billions of dollars of infrastructure. Sea level rise implies a host of effects that go beyond rising sea levels, including flash floods, urban heat, sea water intrusion into the aquifer and beach erosion.

The gloomiest predictions are based on inaction and continuing a “business as usual” mentality. But the situation isn’t hopeless—in fact, it’s one we can tackle as a community. The more we do and the better we adapt, the softer the landing.

Sea levels are rising in South Florida about six times faster than the worldwide average, yet Miami residents point to a lack of information and a shortage of opportunities to make a positive difference. Frost Science’s Museum Volunteers for the Environment (MUVE) initiative engages local residents by restoring living coastlines. This restoration helps protect their communities and enables individuals to take ownership of adapting to climate change.

Yet, perhaps the best tool in Frost Science’s arsenal is the ability to inform and engage thousands of visitors through original exhibitions. Frost Science was built with a special feature called “flexible furniture.” With plumbing and electricity built into the floor of The Dive level of our Aquarium, we are able to change many of our table top exhibits. Just like a changing coastline, this allows us to continually offer new content to our visitors.

Recently, Wells Fargo, via the National Fish and Wildlife Resilient Cities program, in partnership with the City of Miami and Miami-Dade County, recognized this attribute with a major grant to Frost Science. The funding will help restore three living shorelines around Greater Miami while giving Frost Science the ability to create a series of original flexible exhibits that explain how local coastal ecosystems are protecting us from sea level rise. These exhibits are going live this month in conjunction with The Power of Poison: From the Depth of the Sea to Your Own Backyard {CTA} and Da Vinci – Inventions special exhibitions.

The first sea level rise-themed table top exhibits touch on the power of living shorelines (think: mangroves and dunes instead of seawalls) to protect inland areas from sea level rise and storm surge. We’ve all seen the images of sea walls being breached by waves during Hurricane Irma, rendering them useless. Green shorelines use their living structures to anchor sand in place (dunes), stay above the water through elevated roots (mangroves) and diminish the power of waves using their leaves and roots (saltwater grasses).

But the power of native habitats actually starts offshore, where coral reefs can absorb up to 97% of the power of incoming waves. Taken together, it’s hard not to appreciate these “hard-working habitats.”

Other table top exhibits feature our new Topo Box, an interactive, 3D topographic map that enables visitors to create their own landscapes and shorelines—from snow-capped mountains to the deep sea. Wiggling fingers overhead creates rainstorms, allowing visitors to explore how water moves through the environment and how large weather events might affect areas impacted by sea level rise.

In addition to the Topo Box, the Science Portal allows you to see live video, images and data feeds from research projects around the world. You can also use it to sign up as a MUVE volunteer.

FaviconPushing Back Against Poison 6 Jun 2018, 4:42 pm

As part of the museum’s #ToxinTakeoverMiami, we invited Wendy Stephan of the Florida Poison Information Center-Miami to share her insight.

As educator and epidemiologist for the regional poison control center in South Florida, I get an inside view into the fascinating world of poison. My training in public health (and experience as a parent) have been great preparation for my work educating on an always-changing array of hazards. About a week after I started work at our center at Jackson Memorial Hospital/University of Miami Medical Center, I arrived to find my colleagues in hazmat suits. It turned out to be a drill for the hospital’s decontamination team, but I did briefly wonder if every day at the poison center would be so exciting!

For the most part, the 55 poison centers around the U.S. see similar poisonings from day to day. Why? Every Target or Walmart carries the same cleaners and cosmetics. Prescription-strength and over-the-counter medications are also comparable in Miami or Minneapolis. But locally, we do have some unique poisons that stump even doctors. Among the 250 calls we process each day, we might treat tropical marine poisonings, exposures to exotic plants, and/or herbal concoctions from around the world.

Imagine licking an ice cream cone and having it burn your tongue. Or walking across a tile floor that feels like it’s on fire. These odd sensations are a tell-tale symptom of ciguatera fish poisoning. Ciguatera results from eating a reef fish containing a high concentration of a powerful neurotoxin. Besides “reversal of hot and cold” sensations, ciguatera can also cause diarrhea, vomiting, muscle aches and weakness. If not treated within the first 72 hours, symptoms can last for weeks or even months.

You might think a plant called “angel’s trumpet” would be harmlessly pretty. Not so. People who eat this plant (or sip a tea from its leaves) may find out the hard way that this plant is a killer. Most of the deaths from Brugmansia in the United States occur in our area. Symptoms can include rapid heart rate, hallucinations, increased body temperature, dilated eyes, and flushed face. Our hot weather makes it more likely that victims will dangerously dehydrate and not survive.

Have you ever taken a supplement to stay healthy? One case we treated involved the consumption of a liquid brought from Asia known as “snake wine.” Yes, there was a snake, unknown herbs (and a scorpion!) marinating in bottle of wine in the photo snapped at a local emergency room. Apparently, the person who sipped this supposed cancer preventive was not feeling well at all!

But our work is not all weird or dramatic. Early in my role as educator, I asked Earlene, one of our poison specialists, if she was treating anything exciting. She smiled kindly and said, “No, it’s been the best sort of day – I’ve gotten to tell my callers that everything’s going to be just fine.” As darkly fascinating as work at the poison center can be, she reminded me of the best part of our job – providing accurate information and reassurance to our callers, every day.

FaviconMUVE Joins Forces with FedEx Volunteers to Restore Critical Virginia Key Ecosystem 31 May 2018, 2:04 pm

On a rainy Saturday morning, over 20 volunteers from FedEx joined Museum Volunteers for the Environment (MUVE) for a very wet coastal restoration day. Despite the downpour on May 19, volunteers of all ages helped plant around 400 plants at a restoration site on Virginia Key.

muve-fedex2

This site, which has been nicknamed “The Gap,” has been undergoing restoration since the end of last year. Located in Virginia Key North Point, the gap was a former access path covered in residual invasive vegetation and debris. With the help of the City of Miami and Miami-Dade County, invasive species (such as scaevola and Australian pine) were removed from the area before it was flattened for optimal planting. Once cleared, volunteers were needed to quickly stop invasive plants from coming back.

We identified an area at the top of the dune that was suitable for native plant species to thrive—such as beach creeper, coco plum and saw palmetto—and help the dune from eroding during heavy summer rains. Enter: our FedEx volunteers. This hardworking group dug into the sand and tough rocky terrain to plant over 125 of these plants in record time.

muve-fedex4

Next, FedEx volunteers moved down the dune to plant sea oats. This native species helps create living shorelines by stabilizing sandy areas through their deep roots. In order to plant the sea oats successfully, volunteers first removed the invading ragweed plants that were covering the sand. In its place, volunteers placed sea oat plugs which will quickly grow and out compete the ragweed. Even when it began to rain, volunteers were determined to continue establishing the plants into the dune and planted over 250 sea oats.

Another group of helpers noticed a large amount of debris littering the coastline. Using the marine debris tracker app, FedEx volunteers became citizen scientists by removing and recording the types of debris they found while cleaning the beach. This beach is an active sea turtle nesting area. By removing debris, not only does the beach become more visually appealing, we create less obstacles for these and other protected animals to move around and thrive.

muve-fedex3

Since 2011, FedEx and the Frost Science have been working together to restore subtropical forests in South Florida through the FedEx Cares program with National Fish and Wildlife Foundation. These volunteers are helping to improve our public lands by making them more wildlife friendly and bringing them closer to their native characteristics—which naturally helps protect South Florida during storms. Since Virginia Key North Point has been a restoration project, there has been a decrease in erosion and an increase in native animals such as water fowl and American crocodiles. We are now witnessing one of Miami’s most historical beaches become an inviting environment for both people and nature.

FaviconNabta 20 Jun 2018, 1:00 am

For the people of southern Egypt, the summer solstice once was a time to gather. The monsoon season began about then, bringing enough rain to create shallow lakes. People gathered to water their cattle, and to offer sacrifices to the gods. So it was important to know when the solstice was coming.

At one site, people built what may have been a calendar — a ring of small stones. Some of the stones pointed north, while others aligned with the sunrise on the solstice. And some may have pointed to the rising points of bright stars.

Nabta Playa is near the southern border of Egypt, about 65 miles west of the Nile River. Excavations have shown that the site was inhabited as early as 7,000 years ago. People built structures and dug wells. They also dug burial pits and quarried sandstone. Some of the rocks were used in the calendar circle and the possible sightlines to the stars.

These structures weren’t on the scale of Stonehenge. Most of the rock markers were only a few inches to a few feet tall. And the calendar circle spanned only about 12 feet. Yet that would have been enough to sight the rising of the Sun and stars at key times of the year.

The rocks may have been aligned with Arcturus, Sirius, and Alpha Centauri — three of the brightest stars in the night sky. These alignments could have helped the people of Nabta keep time with the seasons — and with the life-giving rains of summer.

More about the summer solstice tomorrow.

Most of us spend a fair amount of time trying to get rid of the dust in our homes. But some scientists at NASA spend time trying to catch dust. They use high-altitude aircraft to catch particles of dust that come from outside Earth’s atmosphere.

Thousands of tons of cosmic dust enter the atmosphere every year. Most of the particles are grains from comets and asteroids. Collecting them reveals more about these big chunks of ice, rock, and metal. And since comets and asteroids are leftovers from the birth of the planets, the dust grains also reveal a lot about conditions in the early solar system.

So NASA has been flying dust collectors aboard two types of aircraft for more than 30 years — modified versions of a spy plane and a Korean War-era bomber. The craft reach the stratosphere — altitudes of 50,000 feet or higher. Even there, most of the particles they pick up come from Earth — bits of sand, pollen, volcanic ash, and others. But there’s enough space dust to make it worth the effort.

At high altitude, the aircraft deploy flat, round collectors that are coated with a sticky oil. They come in two sizes — as big as a saucer or a dinner plate. The big one catches 20 or so grains of cosmic dust per hour.

NASA scientists sort through thousands of particles to pick out the ones that came from beyond Earth. Other scientists from around the world can then study the dust grains — learning more about the solar system from its tiniest members.
