Marine Hazards in the Surf ZoneBy Patrick Amico, Conservation Biologist

ast week past intern, Ryan Walsh, and I were conducting a fisheries research project on Bald Head Island when we noticed a few marine hazards in the near-shore environment: Carolina stingrays, box jellyfish, and sharks feeding on schools of fish. This time of year there can be many of these animals in the water.

Autumn also brings tropical system swells to our beaches; this increase in wave activity increases the intensity of near shore currents which can be hazards to swimmers. This article will include facts about the most common marine hazards that occur this time of year, and will dispel myths that people have about them.

Women Paddling Through Science

By Kendyll Goeman Collins, Environmental Educator and Outreach Coordinator

“If a child is to keep alive (her) inborn sense of wonder without any such gift from the fairies, (she) needs the companionship of at least one adult who can share it, rediscovering with (her) the joy, excitement and mystery of the world we live in.” – Rachael Carson

In April, the BHI Conservancy was awarded the Paddle Nation Project Grant from Outdoor Nation, a national initiative connecting the Millennial Generation to the outdoors. This grant opportunity supports pioneering projects, like Women Paddling Into Science, and initiatives aiming to connect young Americans with their waterways through recreational paddling. The Bald Head Island Conservancy was one of 25 projects, the only organization in North Carolina, selected by Outdoor Nation and the Outdoor Industry

Association® Paddle Advisory Council from a pool of 150 applicants.

Over the past few months, mother and daughter pairs from the surrounding New Hanover and Brunswick county areas have joined us for exclusive kayak expeditions. These trips focused on proper kayaking techniques, navigational skills and estuarine ecology. The groups participated in a salt marsh cleanup and learned about water quality testing procedures. In addition to covering ferry transportation fees, the award provided for new personal flotation devices and safety equipment.

The Paddle Nation Project grants were made possible by support and funding from the Outdoor Industry Association® Paddle Advisory Council, a coalition of top paddlesport manufacturers, retailers and stakeholders; a $30,000 contribution from Nielsen Expositions’ Outdoor Retailer, the outdoor industry tradeshow held twice each year; and many individuals, manufacturers and retailers in the paddlesport community.

“Recreational paddling is one of the most accessible and impactful ways to introduce young Americans to the outdoors,” said Lili Colby, sales and marketing director for MTI Adventurewear and chair of the Paddle Council. “Though so many of the applications were inspiring, we believe the winning projects will creatively and effectively involve young people in all types of paddling, including kayaking, stand-up paddleboarding, canoeing and rafting.”

The “women paddling through science” trips were conducted by female BHI Conservancy staff members, in a “judgment free zone.” Almost all of the 10 trips were comprised of kayaking novices. The greatest benefit that participants enjoyed was learning from the female staff and interns, from the BHI Conservancy. Young tweens and teens

were able to hear about the different road maps that each staff member took to get where they are today. They also received great advice that will set their job and school applications apart from others. The discussion between participants and staff also demonstrated the malleability of a “love for nature,” and the many jobs available. Girls reported wanting to be everything from engineers to nature photographers. Involving a female family member- mother, aunt, or grandmother, will help to keep the girls on a focused path.

“This project has ushered underserved youth into the realm of science by providing them with a life-long pastime, enabling exploration of the ecologically and economically important salt marsh ecosystem, and exposing them to female scientists with a variety of fortes.”- Kendyll Collins, BHI Conservancy EEOC

Over the next few months, the BHI Conservancy will continue its dedication to introducing youth groups to the uniqueness and importance of a barrier island. The Education Department will be housing troops, clubs, and classes in the on-site dormitory through April. For more information about spending a long weekend with the BHI Conservancy naturalist staff, please email [email protected]. Happy paddling!

Bald Head Island finished its sea turtle nesting season with a total of 119 nests! Averaging 70-80 nests over the last ten years, 119 nests is a 19-year record for the island!

The state of North Carolina also beat its all time record this year with a total of 1292 loggerhead nests to date. The Southeastern United States saw an impressive number of nests this season and we hope that nationwide efforts to protect endangered sea turtles is to thank. Bald Head Island had 117 loggerhead nests and 2 green sea turtle nests this year.

During peak nesting season, our beaches are patrolled nightly to tag any nesting sea turtle that our team encounters. Of our 119 nests, we observed 92 nesting events. Of those 92 turtles, 14 were brand new to Bald Head Island and received two types of tags (PIT and flipper) to help us identify her in the future. The rest of our nesting turtles were previously tagged on Bald Head Island and have been coming here for years. Loggerhead sea turtles can lay 3-5 nests in one season. Twelve turtles laid at least 4 nests on Bald Head Island this year alone!

We begin preparing for nests to hatch on their 50th day of incubation by placing a black runway that leads the hatchlings to the water. 112 of our nests have already hatched and the hatchlings are out to sea! With our last nest being laid on August 26th, we expect hatching season to continue through October.

If you are interested in the chance to see a live hatchling please join us at one of our public nest excavations. Excavations are performed three nights after a nest hatches. The purpose of excavations is to take an inventory of the nest. We want to know how many eggs were laid, how many hatched and sometimes we do find a few live turtles in the nest. Once an excavation is scheduled, the date, time and location is posted on our website and around our campus. If you have any questions please call our information center at 910-338-0911.

30 Years in the Making:Jane Lawton Baldridge, Marketing and Communications Coordinator

As I worked on writing this article I was humbled by the work and words of the founders and, stewards, of the BHI Conservancy. Their foresight, continued endeavors and commitment has strengthened and grown the BHI Conservancy year by year. In their words:

Turtle Toast:“If the promise of the wise man can be held as true—that to everything there is a season, and a time and to every purpose under heaven,Then let us, in dedication saluteThe season of the loggerhead turtleSalute!” —The Turtle Lady (Cindy Meekins) 1984

“We are still running, sustained by shared dreams, powered by creative energy, provoked by our “outrageous ambitions”, guided by thoughtful planning and fully aware of our traditions. Indeed this heritage is our beacon… to live in harmony with nature.” —

Dr. Thad Wester 1984-1985

“Key committees were developed to oversee critical areas of our growth, membership and life endowment.” —Dr. Bill Berne 1986

“…but no responsibility seems more important to

me than to convince people who visit the island that they should not despoil the natural beauty with their trash.” —Edgar Dunham 1988

“The Smith Island Complex is designated a sea turtle sanctuary, that gives a tremendous boost to the Conservancy’s Sea Turtle Protection Program.”—Janet Crisp-Lacy 1989

“Because of you (members), this is one fine organization. The entire island benefits, and the reward is yours…” —Baxter Stirling 1990

“Supporting, enhancing and promoting BHI’s natural beauty is the foremost goal of BHIC. The approved Long Range Strategic Plan begins a building program to house our resources to achieve our goal.” — Paul Hosier 1992

“My most satisfying memory has been the achievement, following the participation and support of many, of a permanent home for the Conservancy.” —Dr. Bob Timmons 1994

And continuing forward: As you read these inspiring words and reflect on how the Bald Head Island Conservancy has grown with the expanding needs of our community, we hope you will consider supporting our Annual Fund.

“The Bald Head Island Conservancy study center provides a beautiful, modern research/education facility located on a nationally significant barrier island complex that features excellent examples of ocean to sound communities including a 191-acre old growth maritime forest preserve. Surrounding development has protection of natural resources as a priority which provides outstanding opportunities for investigation of a wide array of coastal-related topics within a community of highly interested and supportive residents.” —John Taggert, Ph.D. Associate Professor of Environmental Studies, UNC Wilmington 2012

Using Bald Head Island as an example of more sustainable management, imagine what new and innovative adaptations could be carried out within other developed beach communities of North

Dear BHIC members and friends,

I am thrilled to be joining the BHIC family as the Director of Conservation, and I am so grateful for the wonderful staff and volunteers who have already shared their passion and excitement for the Conservancy with me! The mission of the Conservancy is a powerful one – and one that I am extremely proud to work for. My background is quite diverse and includes stints as a State Park Naturalist in New York and Ohio, conservation research and field work with an endangered species of rattlesnake, several years as the Director of Education for Carolina Raptor Center where I led a phenomenal team of educators and bird ambassadors to deliver a strong

environmental conservation message all across North Carolina, and most recently spent three years as a higher education strategist and grant writer at Central Piedmont Community College in Charlotte.

While my experiences have spanned a variety of educational venues and have taken me from central Ohio to upstate New York and finally to North Carolina, the education and conservation threads have run throughout. Education is a powerful tool to inspire people and ensure that we leave healthy ecosystems for future generations. As educators, we can have a meaningful impact on our communities and help our neighbors understand how the choices they make every day can have a positive impact on the environment.

I am so very excited to join Patrick, Kendyll, Jaymie and the rest of the team and look forward to meeting and collaborating with the fabulous Conservancy volunteers and friends. My first day on the island is October 22nd.

Sincerely,Nicki

spring and throughout the summer, bull sharks (Carcharhinus leucas), blacktip (Carcharhinus limbatus) and blacknose (Carcharhinus acronotus) sharks move in closer to shore and may be seen along the beaches of Bald Head Island. In summer and fall, sand tiger (Odontaspis taurus) also known as grey nurse, sand bar (Carcharhinus plumbeus), spinner (Carcharhinus brevipinna) hammerhead (Sphyrna mokarran), scalloped hammerhead (Sphyrna lewini) and bonnethead (Sphyrna tiburo) sharks may move in closer to shore.

While the vast majority of these species avoid humans, they can be dangerous when threatened or approached in poor-visibility conditions. In fall, schools of baitfish such as mullet are close to shore, giving sharks plenty of food. It is best to avoid swimming directly in schools of baitfish. Shark bites are rare, but when they do occur it is often an accidental bite inflicted during a feeding frenzy.

It’s a good idea to avoid swimming when the water is especially turbid or murky, this way sharks can see you. Swimmers should leave shiny jewelry at home, as it can resemble the flashing of fish scales, and avoid sharply contrasting colors in swimwear, shark eyes see contrast vividly. Avoid pre-dawn or twilight swims.

Remember that the risk of shark attack is extremely low. For perspective, there are over 400 species of sharks in the world, and about six species are considered to be dangerous to humans. Another significant figure is that from the year 1580 to 2013, there have only been 36 fatal shark attacks in the mainland United States. In 2012, there were only 2 shark attacks in North Carolina, and neither were fatal.

Box JellyfishNorth Carolina is home to many species of jellyfish, most of which are harmless to swimmers. The most common ones are moon jellyfish and cannonball (a.k.a. cabbagehead) jellyfish. Moon jellyfish are very clear and identified by red or

pink four leaf clover markings on its back. The cannonball jellyfish are often brown or purple in color, look similar to a cannonball shape and wash up on the beach in massive seasonal die-off events. Both species are harmless with no to mild stings.

Box jellyfish, also known as sea wasps, are a venomous jellyfish. There are several species of box jellyfish in the world. The box jellyfish has four corners and thin, darker tentacles extending downward from the corners. The tentacles contain

thousands of stinging cells called cnidocytes. They often are 6 to 7 inches in size. The most dangerous box jellyfish are located in the South Pacific region. The box jellyfish in our area, Chiropsalmus quadrumanus, are far less dangerous.

For most swimmers, an encounter with a box jellyfish can cause a painful sting. For those with allergic reactions to the sting, it can be more serious. There is a known population of these animals found along the mouth of the Cape Fear River, including the West Beach area of Bald Head Island. The two other jellyfish-type animals in our area that can cause a painful sting include the Portuguese Man of War and Sea Nettles. Near shore numbers of jellyfish may be increasing from increased food sources; pollution from agricultural runoff increases the number of planktonic animals that jellyfish feed on.

According to New Hanover Regional Medical Services, if you receive a jellyfish sting: • Rinse the area well with ocean water.

• Use the edge of a credit card and gently scrape any remaining tentacles off the skin.

• Combine 1 cup of baking soda and 1 gallon of fresh water in a bucket and rinse the affected area for 20-30 minutes. Vinegar also helps to reduce pain.

• Do not use fresh water on its own, ice or hot water, this can cause the nematocysts to continue to releasing toxins

• If symptoms persist or if swelling begins, seek immediate medical attention

Stingrays and skatesSkates and rays are both related to sharks. Most skates are not really capable of harming people, but sting rays can inflict painful and sometimes serious injuries to swimmers. The stingray we noticed on the beach at Bald Head was an Atlantic stingray (Dasyatis Sabina).

North Carolina is home to many species of skates and rays. Most stingrays are ‘kite-shaped’ in appearance with skinny, stream-lined tails. Skates are often round or triangular and have wider tails with no stinging barb. In our area there are several types of rays: butterfly, spotted eagle, cownose, Atlantic and southern stingray. The common types of skates are: clearnose, barn door, winter skate and little skate.

When rays are threatened, they thrust their tail upward towards the source of the threat. If they make contact, a serrated and venomous barb can pierce the skin. Because the barb is serrated, don’t try to remove the barb as it can do more damage when removed. Seek professional medical

attention if you are struck by a stingray. Sting ray injuries will result in a painful wound that could be coupled with muscle cramps, swelling, nausea and diarrhea.

Most stingray injuries occur when bathers accidentally step on the animal. In the mid to late summer and early fall months practice the ‘stingray shuffle’ when wading out to the ocean. This means shuffling your feet along the ocean floor rather than taking large steps.

Rip Currents and Longshore DriftThere are many myths surrounding rip currents along our beaches, which are often misclassified as ‘undertoe’ or ‘rip-tides’. They do not pull people underwater. In reality, rip currents are channels of water moving away from the beach. They are always present on beaches with breaking waves, but when waves are bigger, rip currents are stronger.

Rip currents form at breaks in between sandbars, and along piers and jetties. Rip currents are common, even found along the beaches of the Great Lakes. Rip currents can be dangerous because they can pull swimmers away from shore. They do not carry people indefinitely out to sea, most end their ‘conveyer belt’ action when they reach the last line of breaking waves near shore. At this point, their energy dissipates. The reason many swimmers get in trouble in rip currents is because they panic and attempt to swim against the flow of current. Rip currents can be faster than the fastest Olympic swimmers can swim, so swimming against them is pointless. If swimmers remain calm, they can escape rip currents.

To spot a rip current, there are several telling signs in the water:• A channel of churning, foamy water that is

often different in color from surrounding water• A line of foam, bubbles, seaweed or sandy

sediment present in the area• A noticeable break in wave activity in a

particular area

Island Nature ToursIf you get caught in a rip current, Don’t Panic!• Don’t fight the current• Most rip currents are fairly narrow, so swim sideways,

moving in the direction of the shoreline to escape the flow of the current, then towards shore at an angle

• If you are not able to escape to the side, float or tread water and ride the rip current out until the energy stops (usually in line with the breaking waves or a few yards past)

• You will now be able to swim parallel to shore, out of the rip current area and back in towards shore

• Visit rip.currents.noaa.gov for more information.

Longshore DriftThe other type of current that affects swimmers at the beach is called longshore drift. This current is one that flows parallel to the shoreline. Longshore drift can be non-existent when the wind is directly flowing off-shore, outwards to sea, or directly on-shore, towards land. When

wind is parallel to the beach, and especially when wind speeds are greater than 10mph, swift sweeping downshore currents can form, which can often move at speeds faster than rip currents.

It is best to avoid swimming in the ocean when conditions include severe longshore drift. To an untrained swimmer, longshore drift can move someone a quarter mile down the beach within a matter of minutes. When deciding whether to swim or not, a drift can be spotted by watching the water close to shore, and seeing whether bubbles or other discernable points are moving to either the left or the right in a fast motion. Similar to rip currents, most of the energy from longshore drift is contained in between the sandy beach and the outer line of breaking waves. The effect is lessened on the outside line of breaking waves.

Longshore drift is very important to beaches, especially Bald Head island, because it is the main form of sand transport. It is the beach environment’s natural way of moving sand down the beach, and supplying downdrift areas of beach with sand.
