Lowcountry Expedition Education Packet
Educate. Inspire. Enable. 3
During Lowcountry Expedition, researchers will collaborate on board the OCEARCH vessel, to do
multiple white shark research projects. They will use a variety of methods to obtain samples
and tag sharks with multiple tags (3) to gather data in order to gain understanding about white
sharks in the North Atlantic.
Research projects include; white shark movements in the North Atlantic, to look at their fine
and broad scale movements, their habitat use, residency, and feeding behavior, aspects of
white shark reproduction, impacts of white sharks on the marine food web of the western
North Atlantic, DNA sequence variation of white sharks within and among ocean basins,
nutritional markers, bite force in sharks, and contaminates of emerging concern from U.S.
Atlantic waters.
Some of these researchers will take biological samples from white sharks, like blood, muscle
plugs, reproductive fluids, fin clips, or parasites off of the shark. Some researchers will then use
the results from the tests performed on the samples can then used along with the pings from
white shark movements on the OCEARCH Global Shark Tracker to complete their data sets.
Others will use only the biological samples for their research.
Research using biological samples : Nutrition, Ectoparasites, and White Shark Reproduction.
Example of white shark research that use both: DNA analysis, Physiological effects of capture
stress, sensory physiology, and trophic ecology of white sharks in the western North Atlantic.
Other research projects will solely rely on tracking data from active (like SPOT and PSAT tags)
and/or passive (acoustic tags) tracking data.
Example : Movements of White Sharks in the North Atlantic
Little is known about white shark biology, ecology, reproduction, and behavior. The ability to
conduct research experiments on the hydraulic lift, with live white sharks, gives scientists
unprecedented access to these apex predators, in order to continue their vital work that could
lead to conservation efforts to manage this IUCN listed “vulnerable” species toward abundance.

Expedition Mission: Lowcountry Shark Research
Educate. Inspire. Enable. 5
The Lowcountry has marine ecosystems that are used by apex predators like
Great White sharks, Tiger sharks, Bull sharks, and Sandbar sharks. These species
of sharks are keeping the Atlantic Ocean in balance. More data is needed about
these species of sharks and how they use the waters in North Carolina, South
Carolina, and Georgia. By tracking and gathering data on Great White Sharks like
Hilton and Savannah, scientists and researchers gain insight on the migratory
patterns, life cycle, reproduction, and overall health of this vulnerable species.
This research is used to conserve them, so they can have a healthy and abundant
future, and help keep the marine food chain in balance.
Shark Species of the Lowcountry
Educate. Inspire. Enable. 6
Great White Shark
Hilton
Cacharadon Carcharias
Sex: Male
Life Stage: Mature
Size: 12 feet 5 inches
Habitat: Great White Sharks can be found in the ocean, all over the world, preferring water
with temperatures between 54-75 degrees.
Prey
Mature White Shark diet: Mature White Sharks eat marine mammals, such as seals, dolphins,
and whales, they have ben seen feeding on dead whale carcasses. They will also feed on large
fish, such as red drum, tuna, striped bass, and dogfish.
Life Cycle
Reproduction: Researchers think that male white sharks in the Atlantic Ocean may have a one-
year migration cycle, where they return to the meeting site every year. The tagging data
collected from mature male white sharks like Hilton and George, are critical for establishing
mating sites for these apex predators.
Fun Fact: Hilton was named after Hilton Head, South Carolina and was tagged on white shark

Size: 8 feet 6 inches
Habitat: Great White Sharks can be found in the ocean, all over the world, preferring water
with temperatures between 54-75 degrees.
Prey
Immature White Shark diet: At this life stage, white sharks mostly eat fish and rays. Their teeth
are more pointed and narrow than mature white sharks.
Life Cycle
Reproduction: Great White Sharks reach maturity at 20 years old. They are viviparous: They
have a gestation period ranging from 18 to 24 months. White sharks have a live birth to 2-12
pups that are 5-7 ft. long. White Shark Savannah, will help researchers to understand the track
for the immature female white shark track of the North Atlantic.
Fun Fact: Great White Sharks can swim in bursts of 25 mph and travel long distances during
their migrations. Lydia traveled 35,000 miles in the first year after she was tagged!

Prey:
Mature Tiger Sharks are known to eat just about anything they come across in the
ocean. Their teeth strong and are able to open up sea turtle shells, and have been
known to eat sea turtles, fish, and birds.
Life Cycle and Reproduction :
Matura tiger sharks are oviviparous. This means that female tiger sharks have egg
casings inside their rooms that then hatch and give birth to live young pups. The
tiger shark is the only one and it’s family that reproduces in this way.
Fun Fact: Tiger Shark Weimar was named after Ruth way Mara who so generously
hosted OCEARCH in Savannah, during Lowcountry Expedition.

Lowcountry Marine Ecosystems
Pelagic Sargassum Habitat Restricted Area
Pelagic Sargassum Habitat Restricted Area
The Pelagic Sargassum Habitat Restricted Area is a designated area in the Atlantic Ocean
ranging from North Carolina to Florida. It is named for the kind of brown seaweed that is found
floating through the Gulf Stream called sargassum. As a seaweed travels through the Gulf
Stream it provides a floating ecosystem as part of the Atlantic marine food chain. The
sargassum itself is food for many juvenile fishes, as well as protection from, larger fishes, who
are preyed on by apex predators, like great white sharks in the ocean.
Pelagic Sargassum Marine Food Web
According to NOAA, the Pelagic Sargassum Habitat Restricted Area is home 81 different fish
species. North Carolina , South Carolina, and Georgia have fishes like, Sargassum Fish,
Planehead fish, Dolphin fishes, and Triggerfish. Other fish species that use the sargassum
habitat include Amberjacks and Tuna; even sea turtles have been seen using the sargassum.
Great White Shark Mary Lee has pinged in several times in this area. This is a sign of a healthy,
thriving, ecosystem. Use the OCEARCH Global Shark Tracker to see which other sharks have
visited the Pelagic Sargassum Habitat Restricted Area. Juvenile Loggerhead Sea Turtles also take
refuge in the sargassum and use it as a food source. Other marine life that use the Sargassum
Habitat Restricted include; dolphins, juvenile Jacks and Pufferfish, and filefish.

Tracking Technology
PSAT tag: The Pop-off Satellite Archival Tag can record data and take measurements of water
temperature, salinity, depths, and location. This tag stays on the shark for a certain amount of
time and then the battery dissolves the tag attachment, and the tag releases and “pops-up” on
the waters surface and transmits it’s location to a satellite for retrieval. This tag is usually
placed at the bottom of the dorsal fin.
S.P.O.T tag: Smart Position Or Temperature transmitting tags are used to track apex predator
sharks in real time . They are the most advanced tag and records database on salinity,
temperature, depth and location. When the SPOT tag is out of the water for 90 seconds, it
sends a signal to a satellite and transmits the data. This tag is placed toward the top of the
dorsal fin. The ping is then uploaded onto the OCEARCH Global Shark Tracker.
Internal Acoustic tag: Internal Acoustic Tags are surgically placed in the space near the stomach
of the shark and closed up with a couple of stitches. It is a very small cut and the shark heals
very quickly. The tag will send sounds that are picked up by a receiver and the tag number is
recorded.
When you see a shark ping in on the OCEARCH
Global Shark Tracker, the pings is the result of
the shark’s SPOT tag sending a signal to a
satellite, telling where a shark is located.
That information is used to track the migration
patterns of the shark and see where it is and
when it’s been there.
We can learn all kinds of different things about
sharks from the tags that are on them. Each
tag gives a different set of data or is put on a
shark for different reasons.

and researchers use to learn more about Great

Introduction
Captain Brett McBride is an expert waterman, fisherman, boat captain, and fishing engineer.
Each expedition presents its own set of challenges and obstacles on and off the water. Little
is known about white sharks in the North Atlantic Ocean. Therefore, scientists need safe
access to these apex predators in order to gather telemetry data and biological samples. To
do this, they look to Captain McBride and the fishing team, to safely find, capture, and release
these sharks. Finding, tagging, and releasing white sharks that can reach 16 feet and weigh
3,500 pound sharks isn’t easy. It requires intuition, experience, and mental toughness. It can
be hard on gear, and be physically straining on the crew. This collaboration though, is
providing unprecedented access and data that is used to help manage these and other species
of sharks toward abundance for a healthy ocean.
Captain McBride has to use ingenuity, leadership, and critical thinking skills to serve the
ocean, help scientists, and care for each shark that comes on the lift.
You can use these skills to solve problems, create new inventions, and show leadership too!
Activity
Watch the “OCEARCH Lowcountry Fishing Brief” and “OCEARCH at PRSF Maritime Center”
to see how Captain McBride uses these skills. There are 2 scenarios as part of this activity;
one is a problem to solve, and one is in need of an invention. Go through the steps on the
pages below, and conquer your own set of obstacles! These scenarios can be solved as
individuals or in a group. You can also share and discuss your ideas, applications, and
conclusions at the end of class!
The Steps
To work through these scenarios, here are some steps you can follow to help guide you.
1. Identify the need or the problem.
2. Research and brainstorm ideas
3. Create or Design
4. Budget materials
5. Construction

Grades 6 and up
N.G.S.S. : Engineering Design: MS ETS1-1-4 and HS-ETS1-1-4
Scenario 1: We’re going to need a better rope.
Researchers are looking to gather data on a large, mature, female white shark. The
data gathered about her may give researchers the answers they need about female
white shark reproduction. They are hoping to be able to get the first pregnant white
shark ultrasound and hormone levels. You are assigned to the OCEARCH fishing
team and to find, tag, and release the safely. While fishing, you see a 16 foot, 3500
pound female white shark, like Mary Lee, investigating the tuna head you have on
the end of a large circle hook and that hook is attached to a 4 ply poly rope. The
shark swallows the tuna and the hook is placed on the side in the corner of her
mouth. However, when the shark bites down on the tuna and hook, it also bites
through the rope. The shark swims away and spits out the circle hook, getting a
free meal. The rope wasn’t strong enough to withstand the force of her bite, nor
the her sharp, serrated teeth.
We’re going to need a better rope. We can’t use cable alone, because it could cut
into the shark or the hands of the crew member holding the cable. The material of
the rope is great because it is able to float and doesn’t corrode. What would you
do? What could design and create to solve the problem?

Scenario 2: Design A Decoy
Scientists and researchers need more telemetry data and biological samples from
immature male white sharks in the North Atlantic Ocean. Little is known about the
diet of young, immature white sharks though, and you are asked to lead the
OCEARCH fishing team in an area that you haven’t been before. The tracking data,
and time of year, indicates that these immature white sharks use this area
frequently. You decide to bring the white sharks closer to the boat, by making a
decoy. A decoy will get the shark’s attention, causing it to investigate it with its
mouth. When it opens its mouth, you can then bait the shark with the fish and place
the circle hook in the corner of its mouth. The bait and switch technique. Baiting
the shark in this way keeps stress at a minimum.
Since you are unsure what the shark’s interest would be in a decoy, what shape
decoy would you use? Why? What material or materials would you make it out of?
How will you get it to float? Would you add any modifications to a traditional
decoy? Plan and design a decoy for an immature white shark to help the science
team collect the samples and gather the data thy need to help manage white sharks
toward abundance.

Essay and Reflection
Name_______________________________________________________________________
No matter what path we choose in life, we have opportunities to serve, and leave this world a
better place than how we found it. Everyone at OCEARCH believes they are meant to serve,
help, and protect, sharks and the ocean. Chris Fischer encouraged everyone on Lowcountry
Expedition to stop from time to time and think, “Am I in balance with the ocean? Am I taking
more from it, than I give back?” Reflect on this and write an essay about where you are in the
balance. Do you take more from the ocean than you give? Do you leave trash behind when you
go to the beach? Use a lot of single use plastic bags and bottles? Recycle? Do you go on beach
or park clean ups? What areas could you improve on?
