60-Second Public Service Announcements
This is SeaTalk: Ocean News from the University of Delaware. Although winter temperatures are not conducive to activities such as swimming and sunbathing, the winter beach offers new and refreshing opportunities for beachcombing and wave watching. The most common waves gently break along the shore, but winter storms can produce large swells that plunge dramatically -- hurling themselves upon the beaches. Wave watching can give you a new appreciation and understanding of wave power and wave impact on Delaware's beaches. For more information on wave watching, call the Marine Advisory Service at (302) 645-4258. That's (302) 645-4258. 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. Scallops are bivalves, meaning that their shell consists of two halves or valves, which are hinged at the top. The distinctive shell is scallop-edged and fan-shaped with radiating ribs or grooves and concentric growth rings. Near the hinge, the shell is flared out on each side forming small "wings." A thin membrane called the mantle surrounds the body of the scallop and secretes the shell. Just inside the shell, along the mantle, is a row of short sensory tentacles and a row of small blue eyes. Each eye has a lens and a retina and they all work together to detect changes in light and motion and alert the animal to danger. What is amazing is that some species of scallops can possess over a hundred eyes!

This is SeaTalk: Ocean News from the University of Delaware. Although our fastest freestyle swimmers can swim at speeds of four miles per hour, this must seem like a crawl to the sailfish, which has been clocked at speeds of up to 68 miles per hour. The sailfish weighs approximately 40 pounds and is 7-feet long with a spear-shaped bill. It is named for the large, dark-blue dorsal fin on the top of its body that is shaped like a sail. The speed of the sailfish makes it a challenge to catch and contributes to its popularity among sports fishermen. In fact, sailfish have been so popular that there has been a noticeable decline in their numbers. As a result, many fishermen who fish for sailfish participate in the "catch and release" program and release the sailfish once they have caught it.

This is SeaTalk: Ocean News from the University of Delaware. The Delaware River port system is the fourth largest in the nation. Throughout the year, approximately 3,000 ships traverse the river carrying over 70 million tons of cargo. This insures that the shipping lanes of the Delaware River are always busy -- even in the winter. In fact, the number of ships that deliver fresh fruit from South American countries peaks during the winter months. In addition, winter does not stop commercial fishing. However, cold temperatures bring the possibility of a frozen river, which may interrupt and even stop the flow of traffic. The U.S. Coast Guard Cutters Capstan and Cleat can break ice up to 18 inches thick, keeping the river clear. The tugs are year-round vessels that also are used in a variety of search-and-rescue missions.

This is SeaTalk: Ocean News from the University of Delaware. Ships that enter the Delaware Bay from the Atlantic Ocean must navigate through hazardous shoals. In the late eighteenth century, these shoals claimed many ships, which resulted in the loss of life and cargo. To help guide ships through these treacherous waters, Philadelphia merchants held a series of lotteries to raise money to build a lighthouse. In 1765, the Cape Henlopen Lighthouse became a reality when it was built on a sand dune, which was located north of Rehoboth Beach and east of Lewes, Delaware. Although it was originally built one-quarter mile from the sea, the encroaching sea was within 150 feet of the lighthouse in 1915. The sea finally claimed it in April 1926 when the lighthouse collapsed. Luckily, with the building of the Brandywine Lighthouse in 1914, the Cape Henlopen was no longer being used.

This is SeaTalk: Ocean News from the University of Delaware. With the return of warmer weather, many coastal property owners begin to think about gardening and landscaping. Whether you're replanting and repairing areas damaged by winter storms or preparing a new gardening plan, before planting consider the unique conditions such as salt spray, wind, sandy soil, and high temperatures that are prevalent in coastal regions. Native plants are uniquely adapted to these growing conditions, and many native species have very attractive foliage and fragrant flowers. With a little preparation and planning, coastal landscaping can be a breeze. For more information on coastal landscaping, 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. Marine scientists at the University of Delaware recently used an instrument called a "towfish" to create new maps of the Delaware River bottom from Burlington, New Jersey, to New Castle, Delaware. The towfish, which is towed underwater, transmits acoustic energy to the river bottom. The sound that is reflected off the bottom is recorded and converted into images that are then digitally "stitched" together to produce a composite map. This technique is able to distinguish between the different types of sediment and can therefore provide information about issues that affect the Delaware River such as contaminant dispersal and shoaling of navigable channels. These maps are not only the first to have been created from this technique in the Delaware River, but also offer the most complete coverage of the river bottom in this area to date. 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. The horseshoe crab is an integral part of the ecosystem of the Delaware Bay. In May and June, more than a million horseshoe crabs can come ashore during the high tides associated with the full moons to spawn and bury their eggs. These eggs are an important food for hundreds of thousands of shorebirds that migrate from Central and South America to their breeding grounds in the north. The horseshoe crab is also important to humans. For example, a chemical in the blood of the horseshoe crab can be isolated and used to test medicines for bacterial contamination. Each spring, the Sea Grant Marine Advisory Service conducts a census to count the number of horseshoe crabs along Delaware Bay Beaches. For more information, call (302) 645-4253. That's (302) 645-4253. 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. Loggerhead turtles, which can weigh up to 400 pounds, are the most common sea turtle in U.S. waters. Although their major nesting areas are in South Carolina, Georgia, and Florida, the Delaware Bay is an important habitat for sea turtles in the summer and fall. Loggerhead turtles have a reddish-brown, heart-shaped shell and are named for their large head, which is approximately 10 inches wide. When active, they must swim to the surface every few minutes to breathe. When resting, however, they can stay underwater for as long as two hours. If you are a recreational or commercial boater, keep your eye out for these interesting sea creatures that also spend time floating on the surface of the water. 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. The Crab Cake Cook-Off is one of the most popular activities at UD's annual Coast Day festival. Although the contest is still a few months away, now is the time to start testing your recipe. All recipes are due on Friday, August 15. Doris Hicks, cook-off coordinator, and a select group of seafood professionals will choose eight recipes for the contest. These finalists will prepare their recipes for a panel of judges at Coast Day on Sunday, October 5, at the College of Marine Studies' campus in Lewes, Delaware. First- through third-place winners will receive cash prizes. For more information and a copy of the rules and registration form, call Doris Hicks at (302) 645-4297. That's (302) 645-4297. 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. The tide comes in, and the tide goes out -- it's a continual process. For most of that time, the water moves quickly with a strong current. However, at slack tide, which occurs approximately one hour after high tide and low tide, the water moves at its slowest speed. Some anglers suggest that this is the best time to catch fish -- it is easier for fish to feed when they don't have to fight the water current. So before you get that rod and reel in hand, be sure and check the tide tables. If this timing doesn't fit your schedule, all is not lost. Areas where there is a drop-off in the bottom of the ocean or bay also create areas of still water where fish can more easily feed.

This is SeaTalk: Ocean News from the University of Delaware. Free tours of the Graduate College of Marine Studies research complex
in Lewes are available to the public. The tours are guided by trained
volunteers, called docents, and typically begin with a 20-minute video
that highlights many of the college's research activities. The video is
followed by a one-hour walking tour of the college's labs where faculty
and graduate students can often be observed conducting research on a wide
variety of topics. The tours, which are available Monday through Friday,
from 10 a.m. to 3 p.m., should be scheduled one week in advance. For more
information, please call (302) 645-4346; that's (302) 645-4346. This is

This is SeaTalk: Ocean News from the University of Delaware. A rip current can sweep even the strongest swimmer out to sea. Rip currents are formed when a break in the underlying sandbar funnels water out to sea in a narrow channel. The resulting current can be so strong and so swift that even the most experienced swimmer can be caught. If you get caught in a rip current, don't panic. Most rip currents are only 10 to 30 yards wide and dissipate as they flow into deeper water. Swim parallel to the shore until you are out of the current or let it carry you until it dissipates. A rip current can be recognized by any of the following tell-tale signs: a channel of choppy, muddy-colored water flowing out to sea; a line of foam, seaweed, or debris floating out to sea; a section of choppy water; or a break in the surf as the waves roll toward the shore. 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. Seafood is naturally nutritious, and it's low in calories and total fat. The fat that is generally found in seafood is rich in polyunsaturated fatty acids, which lower blood cholesterol. Fish also is unique in that it contains a large proportion of highly unsaturated omega-3 fatty acids -- fat that is essential for life. Because humans cannot manufacture these fats, they must get them through their diet. Most seafood also is high in protein, low in sodium, and packed with vitamins and minerals. For more information about incorporating seafood into your diet, call the Sea Grant Marine Advisory Service at (302) 645-4346. That's (302) 645-4346.

This is SeaTalk: Ocean News from the University of Delaware. Delaware Sea Grant researchers have developed a molecular probe that can rapidly detect the microscopic algae that causes brown tide, a phenomenon that can occur when high concentrations of algae, called "blooms," discolor water. The probe is so sensitive it can detect the presence of just a few cells of algae per milliliter of water. This is well before the blooms occur. Brown tide is not harmful to humans or fish, which can simply swim away or avoid the blooms. It may, however, harm marine organisms that are not able to move, such as eelgrass and clams and oysters. 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. Many people return from a day at the Delaware beach with a pile of seashells. Most of these shells belong to either the bivalve or gastropod class of the animal kingdom. Bivalves have developed two shells, which are attached at one side by a hinge, to protect their soft body. Common bivalves include clams, scallops, and oysters. Gastropods, on the other hand, such as conchs and snails, have only a single shell that is either cone-shaped or spiraled inside. Most gastropods also have a foot that they use to move around in search of food. The foot is pulled into the shell when the animal is frightened.

This is SeaTalk: Ocean News from the University of Delaware. Seaside goldenrod can be found flowering, from August through October, in sand dunes and along the margins of coastal salt marshes throughout the Mid-Atlantic region. The plants are approximately 3- to 4-feet tall with bright yellow blossoms on arched branches. The clusters of daisy-like flowers tend to be larger on seaside goldenrod than those found on inland goldenrod varieties. In addition, its dark-green leaves are thick, smooth, and fleshy, which is an adaptation to the drying effect of salt spray. Native to coastal areas, seaside goldenrod can be used for dune restoration and wildlife habitat; it is especially attractive as a food source for migrating monarch butterflies.

This is SeaTalk: Ocean News from the University of Delaware. A responsible boater operates a boat not only safely, but also in an environmentally friendly fashion. This is even more important in Delaware's Inland Bays because their shallow nature makes them highly susceptible to environmental problems. Environmentally friendly practices do not need to incur added expense, but can simply mean doing things a little differently. For example, fish waste can be thrown overboard in deep waters, but if you are near a marina they should be disposed of in the trash. And don't top off your gas tank, but only fill it to 90 percent because the fuel will expand as it warms up. For a free card with tips on how to be a responsible boater, call the Sea Grant Marine Advisory Service at (302) 645-4346. That's (302) 645-4346.

This is SeaTalk: Ocean News from the University of Delaware. There's a new pier in the river! Located at the confluence of the Delaware
and Christina rivers, the auto and "RoRo" berth is designed
to accommodate special purpose ships that carry vehicles like automobiles
and trucks. It is 875 feet long and 115 feet wide, and it is constructed
900 feet offshore, parallel to the coastline. The new pier will enable
the Port of Wilmington to attract new customers, which, in turn, will
generate new jobs and tax revenue for the state of Delaware. Founded in
1923, the Port of Wilmington is a full-service, deep-water port and marine
terminal that handles over 400 vessels per year with an annual import/export
cargo tonnage of 5 million tons. This is SeaTalk, a public service announcement

On November 29th, marine scientists from the University of Delaware will begin Extreme 2003 -- a deep-sea research expedition to hydrothermal vent sites nearly 2 miles deep on the floor of the Pacific Ocean. Using the research vessel Atlantis as their base of operations, the scientists will descend for nearly two hours in the submersible Alvin to these "hot springs" of the ocean. Once on the ocean floor, the scientists have only four to five hours to collect samples and conduct research before they must ascend to the surface. An interactive Web site will let the public travel along with the scientists as they conduct research in this extreme environment. Join the Extreme 2003 expedition at www.ocean.udel.edu.

This is SeaTalk: Ocean News from the University of Delaware. During the summer months, the waters of the ocean and bay are teeming with blue crabs that are constantly searching for food. Do you ever wonder what happens to all of these busy little crustaceans during the winter months? As the days get shorter and the water gets colder, instead of going south or migrating to warmer weather, they go down. Down to the deep water, and down to the bottom. In these watery retreats, they burrow into the sand or mud on the ocean or bay floor leaving their eyes and antennae exposed. They remain there throughout the long, winter months. During this period of dormancy, the body functions of the crab slow down. As a result, it does not have to bulk up or eat to stay alive during this period of inactivity. This is SeaTalk, a public service announcement from the University of Delaware Sea Grant College Program and this station.
