Beachcombing (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Beachcombing — walking along the beach to see what treasures have washed ashore — is fun to do on a summer day. But try it this winter and you’ll learn what the best beachcombers know: The season’s strong storms and lack of crowds leave behind the most amazing finds! Driftwood, egg cases, and shells are among the objects you might encounter. You might also come across a piece of sea glass, which is glass that has been tumbled smooth by water and sand. Or maybe you’ll find some coral, a whelk, or a sand dollar. Just be sure to leave live organisms where you found them because most can’t survive outside their natural habitat.

Winter Wetlands (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
As summer wanes and days grow shorter, the lush plants of the region’s wetlands fade from green to brown. But they’re not done working yet. Their decomposition adds nutrients to the ecosystem and builds up the marshy soil, keeping the diverse habitats above surrounding waters. However, in many places rising sea levels are outpacing the ability of these plants to rebuild the earth beneath them. As they drown, these natural treasures are lost, so Delaware Sea Grant researchers are working to identify the best varieties of native plant species to take on the rising waters, and keep Delaware’s vital wetlands standing tall.

Polar Research (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Penguins and polar bears might spring to mind when you think of the world’s polar regions. But some UD scientists are making trips to the Antarctic and Arctic to study the freezing water’s tiniest inhabitants. They’re conducting research on marine microbes, which are plants and animals that are so small more than a million of them can fit into just one teaspoon of seawater. The scientists are determining how the microbes grow in the extreme conditions at the ends of the earth. Knowing this information will help them better understand the role that microbes play in the environment’s natural cycles, as well as better predict the impact that global climate change would have on the ecosystem.

Teacher of the Year Winner (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Congratulations to William Geppert, the 2008 Governor’s Marine and Aquatic Science Teacher of the Year. Geppert, who teaches 11th and 12th graders at Cape Henlopen High School in Lewes, was chosen based on four major criteria: creativity, innovation, quality of teaching, and impact on students. The Delaware Sea Grant College Program and the Office of the Governor established the award seven years ago, recognizing the importance of educating students about marine and aquatic resources. You can meet Mr. Geppert at Coast Day, October 5th at the University of Delaware’s Hugh R. Sharp Campus in Lewes. There he will share his award-winning project ideas and teaching techniques.

What is a Harmful Algal Bloom? (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
If you live near water, you may have heard the term “harmful algal bloom.” HABs, as they’re called, are caused by a small group of micro-organisms that grow rapidly under certain environmental conditions. These large outbreaks have increasingly affected marine and freshwater areas throughout the country. Some blooms have been known to kill fish, birds, and marine mammals, and their presence in shellfish and sea air mist can harm human health. Delaware Sea Grant scientists are researching ways to better monitor HABs and determining what kinds of environmental changes trigger certain types of blooms. This is SeaTalk, a public service announcement from the University of Delaware, the Delaware Sea Grant College Program, and this station.
Hurricane Research (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
With winds that can exceed 155 miles an hour and torrential rains that can cause dangerous flooding, hurricanes can cause substantial damage along coastlines and further inland. Over the past 30 to 40 years, scientists have gotten better at predicting where a hurricane will make landfall after crossing the ocean. Now, Delaware Sea Grant researchers are taking on another challenge. They are studying how the ocean interacts with the air moving above it. This information will help experts estimate the intensity of a hurricane when it hits land — and as a result save lives

Electric Car Technology (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
The price of gasoline might affect this year’s summer road trip, but a new technology could change that for the future. University researchers have created a system that enables vehicles to not only run on electricity, but also to store and provide electricity for utilities. The technology lets electricity flow from the car’s battery to power lines and back. This capability could earn cash for the cars’ drivers. Utilities currently pay millions to generating stations that help balance the grid, but researchers say the the value of each car providing that same service could be around $4,000 a year, some of which could be paid to drivers.

Fish Research(0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Anglers dream of the next big catch, but a research project has University of Delaware scientists looking for the region’s tiniest fish. The researchers are studying how changes in environmental conditions and climate influence movement of fish larvae from open ocean waters into Delaware Bay. Successful movement of larvae from offshore spawning areas into bay and river nursery areas where young fish grow up is a critical step in ensuring healthy populations for fish such as Atlantic menhaden, Atlantic croaker, and American eel. The researchers’ work will help fisheries managers understand causes for natural variability in numbers of these fish.

Ghost Crabs(0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Those flashes you see moving across the beach aren’t phantoms — they are fleet-footed animals called ghost crabs. These sand-colored crabs leave their beach dens along the Delaware coast between dusk and dawn to scurry down to the water. There, they feed on smaller animals at the surf's edge and wet their gills so they can breathe. Then they race back to their burrows, which can extend as far as 4 feet into the sand, keeping them safe and cool during hot summer days. Look quickly — their coloring provides great camouflage and they can move at speeds up to 10 miles per hour!

Swimmer's Itch(0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Swimmer’s itch can really take the fun out of a summer vacation. Also known as clam digger’s itch, the uncomfortable rash is an allergic reaction to a tiny free-swimming parasite sometimes found naturally in shallow coastal waters. The parasite is usually found in birds and aquatic snails. Although it isn’t harmful to humans, it can irritate skin, causing a red bumpy rash and intense itching that can last as long as a week. You can take measures to prevent swimmer’s itch by avoiding water in areas where there are posted warnings, and drying off with a towel or rinsing well with fresh water immediately after wading or swimming.

Analyzing the Economic Value of Shorebirds (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Delaware is a vital rest stop for weary shorebirds as they trek from South America to Canadian breeding grounds each spring. Their visit coincides with the spawning of horseshoe crabs along Delaware Bay’s sandy shores, allowing the birds to gobble up nutritious eggs that fuel the remainder of their journey. Flocks of tourists also come to witness the annual event, and university researchers are studying their economic impact. Their work will help determine the value of shorebirds to local economies as well as the impact of conservation efforts. This could help conserve birds facing the prospect of serious decline.

Lewes Wind Turbine (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
With rising energy prices and concerns about the impacts that fossil fuels have on human health, national security, and climate change, alternative energy sources are getting a close look these days. One of these alternatives is wind power. The University of Delaware is studying whether coastal winds might be harnessed to supply the energy needs of its Hugh R. Sharp Campus in Lewes. If so, wind power might someday provide the campus with cheap, clean energy and help conserve our valuable natural resources for future generations. The study also will provide useful research data for scientists and the public. For more information, visit ocean.udel.edu.

New Horseshoe Crab Model (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
In the spring, thousands of horseshoe crabs come to Delaware Bay beaches to spawn. In order to keep track of the population of this important animal — which is among the world’s oldest creatures — the Delaware Sea Grant Marine Advisory Service conducts a horseshoe crab census in May and June. To help people learn more about horseshoe crabs, the Delaware Sea Grant College Program has introduced a new full-color, three-dimensional model of the animal, which children or adults can assemble in approximately 15 minutes. To order the horseshoe crab model, or to volunteer for the annual census, call (302) 831-8083. This is SeaTalk, a public service announcement from the University of Delaware, the Delaware Sea Grant College Program, and this station.
Sand Dunes (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Sand dunes are mounds or ridges of windblown sand that are vital to shoreline stability. Dunes protect the Delaware coast during storms, provide a reservoir of sand for the beach and sustain a unique ecosystem. The few hardy grasses that live in the dune environment have adapted to multiple stresses imposed by wind, blowing sand, salt spray, sandy soils and heat. Planting beach grass in the spring encourages the development of a healthy root system that will help protect the dunes from the fierce winds and strong waves of the next year's winter storms. For more information about these resilient and extreme ecosystems, call (302) 645-4346.

Help the Coast on Earth Day (0:60)
This is SeaTalk: Ocean News from the University of Delaware.
You don’t have to rearrange your life or spend a lot of money to help the environment. This year for Earth Day, held April 22, consider easy things you can do to protect the coast. Examples include only using the amount of fertilizer you really need, keeping your vehicles properly maintained, taking reusable bags to the grocery store, and putting litter such as cigarette butts in its place. Rain washes excess fertilizer from our lawns, oil from our parking lots and garbage from our streets into our waterways, harming wildlife. By making small changes in your daily life, you can reduce the impact we have on the coastal environment.

Add Native Plants to Your Garden 0:60)
This is SeaTalk: Ocean News from the University of Delaware.
Landscaping can be a formidable task along Delaware’s shore, where salt spray, wind, heat and sandy soils are prevalent. Coastal areas provide an excellent opportunity to use native plants in perennial gardens. Native plantings are attractive alternatives to traditional nursery stock because they require little maintenance and are specifically adapted to heat, drought and soil stresses common to coastal areas. They also provide important feeding, nesting and resting habitat for many birds and animals and can add color and texture to your garden, creating a compatible extension of the natural ecosystem. For more information about native plants for Delaware’s coastal areas, visit ocean.udel.edu/nativeplantgarden. Or call (302) 645-4346.

It might be cold outside, but if you could travel more than 6,000 feet beneath the ocean’s surface, you’d find places where it’s hotter than a summer day. In some areas at the bottom of the sea, water that’s been heated by hot magma deep inside the earth flows through cracks in the ocean floor. These areas are known as hydrothermal vents, and their superheated water can exceed 500 degrees Fahrenheit. That’s more than two times the temperature of boiling water — too hot for most ocean creatures. But organisms such as giant tubeworms and clams that live in clusters around the vents are specially suited for such hot temperatures. They call this extreme environment their home. This is SeaTalk, a public service announcement from the University of Delaware, the Delaware Sea Grant College Program, and this station.

February 2 is World Wetlands Day, an annual international celebration of the importance of wetlands and efforts to conserve them. Wetlands are a valuable part of the environment. They create habitats for many animals, and they filter pollutants such as nutrients. That’s important because extra nutrients can fuel an overgrowth of algae, which deprives waterways of oxygen and can harm fish and other wildlife. Unfortunately, many wetlands may be threatened by rising sea levels and coastal development. University of Delaware researchers are analyzing plants that can withstand these challenges. Such plants would be ideal for helping restore existing wetlands or create new ones.

Have you ever wondered why bay and ocean water doesn’t freeze like fresh water? Fresh water freezes as temperatures dip to 32 degrees Fahrenheit. But salt lowers the temperature at which water freezes. That’s why we use salt on roads to prevent the formation of ice. So for the saltiest water off Delaware’s Atlantic coast to freeze, the thermometer must drop to 28.6 degrees. As salt water begins to freeze, it develops as slush — it doesn’t form a continuous sheet as it would on a freshwater pond. That’s why during a Delaware winter you’re more likely to see a slushy surface of ice crystals along a bay shoreline, silently undulating as waves break beneath. This is SeaTalk, a public service announcement from the University of Delaware, the Delaware Sea Grant College Program, and this station.
