This is SeaTalk: Ocean News from the University of Delaware. While many people are breathing a sigh of relief that hurricane season is over, the winter months often signal an increase in the number of storms known as northeasters. These coastal storms develop around regions of low pressure and are fueled by strong temperature contrasts between cold northern air and warmer southern air masses. Northeasters typically produce higher than normal tides with waves ranging from 5 to 15 feet high and winds of 30 to 40 miles per hour. Unlike hurricanes, which are here today and gone tomorrow, northeasters can stall just off the coast -- increasing the amount of damage to beaches and coastal communities. For more information about northeasters, call the Sea Grant Marine Advisory Service at (302) 645-4346. That's (302) 645-4346. This is SeaTalk, a public service announcement from the University of Delaware Sea Grant College Program and this station.
This is SeaTalk: Ocean News from the University of Delaware. Coastal sand dunes are nature's way of protecting ocean shorelines from waves that relentlessly erode the beach. The dunes also keep the storm waters from rushing inland and flooding the coastal communities with salt water. The long winter takes a toll on the dunes, however. As a result, the Delaware Department of Natural Resources and Environmental Control conducts a volunteer beachgrass-planting program in March to help stabilize and rebuild Delaware's coastal dunes. Volunteers are trained on how to plant and supplied with planting poles and bundles of Cape American beachgrass. As the wind blows, the beachgrass traps the sand. As the sand accumulates, the beachgrass grows right up through it, maintaining a protective cover while the dune slowly grows higher and wider. For more information, call DNREC at (302) 739-9921.

This is SeaTalk: Ocean News from the University of Delaware. Seafood has been shown to play an important role in diet. It is a nutrient-rich, high protein food, generally low in calories and total fat. Sea Grant researchers at the University of Delaware are working to determine the effectiveness of various packaging films for fish and fish products. These packaging films are being tested with different levels of antibacterial agents to ensure that seafood is safer to eat and extending the shelf life of fish and fish products. Packaging materials like this would be of benefit to both the seafood industry and consumers.

This is SeaTalk: Ocean News from the University of Delaware. Tides come in, and tides go out -- all in response to the gravitational pull of the moon and sun on the Earth. A spring tide is an exceptionally strong tide, providing the highest of high tides and the lowest of low tides, and actually has nothing to do with the changing seasons. It occurs all year round, during a new moon or a full moon when the moon and sun are in a straight line with the Earth. During a new moon, the sun and moon are on the same side as the Earth; and during a full moon, the sun and moon are on the opposite sides of the Earth. In contrast, a neap tide is an extremely weak tide and occurs when the moon is in its first- or last-quarter phase -- when the moon is located at a right angle to the line made by the sun and Earth.

This is SeaTalk: Ocean News from the University of Delaware. How do you place a price tag on a beach? Rising sea levels, oil spills, other natural disasters, and even human activities can make beach maintenance an expensive proposition. Sea Grant researchers at the University of Delaware's College of Marine Studies are conducting surveys to estimate the economic value of Delaware's beaches based upon the characteristics of a beach and the frequency in which the public uses that beach. Beach characteristics identify features such as length and width, boardwalks, easy access, and parking. The surveys will indicate whether a person is more likely to visit a beach for a day trip or for an extended vacation. The results of this study will help policy makers determine when the cost of maintaining a beach outweighs its value to the community.

This is SeaTalk: Ocean News from the University of Delaware. For fishing enthusiasts, spring isn't heralded by the first robin, but by the annual shad migration. Shad are anadromous fish, which means that they are born in fresh water, like the Delaware River, and then migrate to the ocean, where they spend most of their lives. When they are between four and six years old, they return to the river of their birth to spawn. This migration occurs any time between February and July, depending on the region and the particular weather patterns of the year. Shad like water temperatures between 55 and 61 degrees Fahrenheit, so migration occurs earlier in the warmer southern waters and later in northern areas. During spawning, shad arrive in large schools, running up the rivers where they slowly adjust to the change from salt to fresh water.

This is SeaTalk: Ocean News from the University of Delaware. The horseshoe crabs are coming! The horseshoe crabs are coming! During the high tides associated with the full and new moons of late May and early June, horseshoe crabs come ashore, by the thousands, onto the beaches of the Delaware Bay to spawn. Every year, the Delaware Sea Grant Marine Advisory Service conducts a census of the horseshoe crab population at the peak of the spawning season each year. This information not only helps scientists determine if the population of this hardy creature is being threatened by overharvesting and loss of habitat but also helps guide harvesting policy. To participate in the census and learn more about this valuable marine critter, call (302) 645-4346. That's (302) 645-4346.

This is SeaTalk: Ocean News from the University of Delaware. In times past, stowaways referred to people who hid aboard ocean-faring vessels. Today, stowaways also refer to marine organisms that are transported in the ballast water of ships. These non-native organisms have the potential to threaten native plants and animals, or become invasive, in the port where the ballast water is discharged, causing ecological, socio-economic, and human health consequences. Sea Grant researchers at the University of Delaware's College of Marine Studies are developing a computer model to evaluate and rank the most effective ways to reduce the introduction of potentially invasive species from ballast water as well as those methods that will be the most cost effective. The resulting model will help determine the best policy strategies for dealing with this emerging issue.

This is SeaTalk: Ocean News from the University of Delaware. What is the world's smallest fish? Scientists are now debating this very question. Some say it should be the lightest fish, and some say it should be the shortest. Still other scientists say it should be the thinnest fish. A recently discovered fish, whose adults are less than a third of an inch long and live in acidic swamp waters in Sumatra has renewed this debate. The fish, which is a member of the minnow and carp family, has been claimed in some circles to be the world's smallest fish because it is so short. Other scientists believe that males of a deep-sea anglerfish, which is even shorter, is the world's smallest fish. However, the female anglerfish is much larger -- almost eight times larger than that the male. After hatching from an egg, the male anglerfish fuses itself to a female, creating what is essentially a single creature.

This is SeaTalk: Ocean News from the University of Delaware. Scientists are becoming increasingly concerned about a phenomenon known as ocean acidification. Carbon dioxide in the atmosphere dissolves in the ocean and reacts with seawater to form carbonic acid. The chemistry and biology of the ocean has adapted to a certain level of acidity, or pH, and it has been that way for hundreds of millions of years. In recent years, however, the acidity of the ocean has increased. Human activities, such as burning fossil fuels, have increased the levels of atmospheric carbon dioxide. This excess carbon dioxide has raised the acidity of the ocean. Ocean acidification has implications not only for the ocean ecosystem, but also for critical marine resources like fisheries, coral reefs, and the plankton that support nearly the entire ocean food chain. In the short term, ocean acidification may kill organisms that cannot adapt to these changing conditions.

This is SeaTalk: Ocean News from the University of Delaware. Rip currents are extremely strong and fast-moving currents that flow out to sea -- they are so powerful that they can sweep even the most experienced swimmers off their feet. In an effort to improve rip current predictions, Sea Grant researchers at the University of Delaware and at Johns Hopkins University in Baltimore, Maryland, are establishing a beach monitoring system at Bethany Beach, Delaware, and Ocean City, Maryland. Video cameras will be installed to monitor surf zone conditions and seabed changes. This footage will be correlated with lifeguard observations of rip conditions from the ground to help identify the mechanism that causes this potentially deadly hazard. In addition, the scientists will use wave data to validate numerical models that simulate the environment in which rip currents occur. Improving the prediction capability also will reduce the number of false alarms, which undermines the seriousness of this hazard.

This is SeaTalk: Ocean News from the University of Delaware. Thunderstorms, northeasters, tropical storms, and hurricanes can all cause flooding -- one of the deadliest tricks in Mother Nature's weather bag. In the United States, for example, floodwaters have claimed nearly 140 lives every year for the past 30 years. Most floods develop slowly over a period of days. Flash floods, however, can develop in a matter of minutes. Water that was only 6 inches deep at one moment could easily be 2 to 3 feet deep only seconds later. For an 11- x 17-inch color poster with flood-safety tips, call the Delaware Sea Grant Marine Advisory Service at (302) 645-4346. That's (302) 645-4346.

This is SeaTalk: Ocean News from the University of Delaware. Do you have a taste for clams? The European green crab sure does. In fact, it
is often blamed for the demise of the soft-shell clam fishery in
Maine. Native to the Atlantic coasts of Europe and Africa, its first
occurrence in the United States is believed to have been in the 1800s
on the East Coast -- in the waters off of Massachusetts. It has since
spread as far north as Nova Scotia, Canada, and as far south as Virginia
and, in 1989, was even discovered in the San Francisco Bay on the
West Coast of the United States. Its voracious appetite for clams
and other shellfish pose a threat to local populations of these organisms.
In the Mid-Atlantic region, the native blue crab has apparently developed
a taste for the much smaller green crabs, which may help keep its
population under control. This is SeaTalk, a public service announcement
from the University of Delaware Sea Grant College Program and this

This is SeaTalk: Ocean News from the University of Delaware. The ocean is a noisy place -- from the sounds made by chattering shrimp to the songs sung by whales. Even the wind that blows across the surface of the ocean creates noise. Marine scientists can now study these sounds aboard the University of Delaware's new coastal research vessel -- the 146-foot Hugh R. Sharp. The most advanced research ship in the United States oceanographic fleet, Hugh R. Sharp was designed to operate more silently than the natural sounds coming from the underwater world. As a result, sounds from the ship will not interfere with the research conducted by the scientists, enabling them to learn more about the "noisy" ocean. For example, the ship can be used for studies that explore how some marine animals use sound to communicate with each other.

This is SeaTalk: Ocean News from the University of Delaware. Striped bass can be found on the Atlantic Coast as far north as Canada during the summer months. With the onset of winter, however, they migrate south to the warmer waters of the Mid-Atlantic. As a result, they are a favorite for the fall and winter fishing enthusiast in this region. Named for the seven to eight dark stripes that run along the side of its silvery body, they also are called stripers or rockfish because they are typically found near rocks and other obstacles on the river bottom. The striped bass fishery is one of the first natural resources in the United States to be regulated, when it was barred from use as a fertilizer in 1639. And, in 1983, its popularity with both commercial and recreational anglers pushed the fishery to the verge of collapse. It has since rebounded, and recent figures indicate catches are at a record high. This is SeaTalk, a public service announcement from the University of Delaware Sea Grant College Program and this station.
This is SeaTalk: Ocean News from the University of Delaware. Low tide can uncover wide expanses of mud in some coastal areas that are sheltered from the harsh action of ocean waves and winds. The dark and smelly mud found in these intertidal mudflats is full of millions of microorganisms that provide food for marine invertebrates such as marine worms and clams, which, in turn, sustain large populations of shorebirds. This critical habitat also helps protect the shoreline from erosion. The morphology, or shape, of these mudflats depends on a number of physical processes. At the University of Delaware, Sea Grant researchers are developing a numerical model to predict how the morphology of these mudflats changes due to future sea-level rise and variations in tidal and wave action. This information is important in planning coastal management projects such as wetland restoration and creation. This is SeaTalk, a public service announcement from the University of Delaware Sea Grant College Program and this station.
