MESSAGES FROM EARTHWATCH
DEAR EARTHWATCHER,
Thank-you for your interest in our Earthwatch project Discovering sharks in South Africa. We can't wait to meet you and have
you join our shark citizen science team!
We are so lucky to live and work in such a beautiful part of the world, and we look forward to sharing it with you. You will fall
in love with our study area - the beautiful Walker Bay in Hermanus. Located right near the bottom tip of Africa, Walker Bay is at
the heart of where two great oceans, the Atlantic and Indian Ocean, meet. The bay is teaming with wildlife, not only the sharks,
but whales, dolphins, seals, fish, lobster and many other animals! South Africa is a stunning country and we hope that you get
the chance to explore more of it before or after your time with us.
Sharks urgently need our help. Approximately 100 million sharks a year are killed and around a quarter of all species are
threatened with extinction. Fortunately, with assistance from people like yourselves, we can help save sharks. With this project,
we will learn more about several shark species that we know very little about and have rarely been studied. Many of these sharks
are endemic species, which means that they are found only in a small area in this part of the world.
You will get up close and personal with these amazing creatures helping us collect vital scientific data, measure, tag and release
the sharks. We will be able to look at their movement patterns through our tagging surveys and assess which habitats sharks are
found in. We will be deploying baited remote underwater video cameras (BRUVs) in areas that no one has ever done so before.
You will help us analyze the footage and you never quite know what may pop up on the screen! We will be trialing a photo
identification study so that we can identify individual sharks by their unique markings. Walker Bay is a seasonal Marine Protected
Area and we will be assessing the effectiveness of the MPA on shark populations.
All this knowledge is invaluable for our quest toward shark conservation. The data that we will be collecting will be used to
inform managers about critical information about shark's behaviors and habitats. Thanks to your assistance we will be making
some great, positive progress toward shark conservation in South Africa and around the world.
Thank-you for your interest in 'Discovering Sharks in South Africa'. We look forward to immersing you into our world soon!
Sincerely,
Earthwatch Scientists, Katie Gledhill, Meaghen McCord, and Tamzyn Zweig
DEAR EARTHWATCHER,
Thank you for joining this expedition! We greatly appreciate your decision to contribute to hands-on environmental science
and conservation.
As an Earthwatch volunteer, you have the opportunity to create positive change. And while you’re out in the field working
toward that change, we are committed to caring for your safety. Although risk is an inherent part of the environments in
which we work, we’ve been providing volunteer field experiences with careful risk management and diligent planning for
over 40 years. You’re in good hands.
We hope this expedition will inspire you to get more involved in conservation and sustainable development priorities—not just
out in the field, but also when you return home. We encourage you to share your experiences with others, and to transfer your
skills and enthusiasm to environmental conservation efforts in your workplace, community, and home.
If you have questions as you prepare for your expedition, contact your Earthwatch office. Thank you for your support,

THE RESEARCH
DISCOVERING SHARKS IN SOUTH AFRICA
THE STORY
Nearly a quarter of shark and ray species worldwide are at
risk of extinction (Dulvey et al 2014). It is estimated that
100 million sharks are killed each year (Worm et al. 2013),
largely due to the Asian shark fin market (Clarke et al
2006). As marine apex predators, elasmobranchs (sharks,
rays, and skates) are species that regulate the ecosystems
they occupy. The removal of shark species from the marine
ecosystem can have a detrimental impact on the entire
food chain (Ferretti et al. 2010). For example, fewer sharks
mean that the population of mid-level predators increases,
which in turn eat herbivorous fish. When these populations
decline, the algae they consume become more abundant on
the reefs, which can smother and destroy the reefs. This
example of the top-down effects of predators is known as a
trophic cascade.
South Africa has some of the richest, most diverse wildlife
of anywhere in the world. This includes a wealth of marine
species, about 33 percent of which are found only in
southern African waters and one of greatest shark
biodiversities globally (Compagno 2000; NPOA Sharks 2012).
While some species of sharks, such as white sharks, are well
studied in South Africa, there is little to no data available
on the many other species of sharks and fish that exist in
Walker Bay – a seasonally protected area in southern South
Africa (Compagno 1999). This study will be the first
comprehensive assessment of the marine biodiversity of the
bay.
7
In 2014, the South African Shark Conservancy (SASC) worked
alongside the world renowned marine biologist, Dr Sylvia
Earle and Mission Blue to declare the Cape Whale Coast
Hope Spot, which Hermanus and Walker Bay are an integral
part of. As Dr Earle states: “We have the knowledge and the
technology, what we need is the will to use it intelligently
to ensure an enduring place for ourselves within the natural
system that keeps us alive.”
methods - Baited Remote Underwater Video Surveys
(BRUVs) and scientific angling. BRUVs will be used to assess
the diversity and abundance of fish and sharks, while
scientific angling will be used to assess shark populations
and collect scientific measurements and photographs for
the photo identification study, as well as collect genetic
samples. Genetic samples will be used to look at the
population structure of sharks on a wider regional, national
and international scale.
The first few study teams will help to collect baseline data
on the species diversity and seasonal abundance of shark
and fish populations in the bay, in addition to studying
which habitats these sharks prefer to spend their time in
and how they move around the bay. This data will form the
basis for a long-term monitoring study looking at how stable
these populations are and how much they vary. You will
also look at the importance of different habitats – including
kelp, rocky reef, sand, and estuarine habitats.
We will compare the species diversity, relative abundance
and economic cost between the two sampling methods:
BRUVs and shark angling. We will aim to assess the
scientific and cost effectiveness between the two methods.
The footage and images from the BRUV footage will be used
for educational and outreach purposes. This footage allows
us to share the beautiful underwater world of Walker Bay to
people who may not usually have access to underwater. The
footage will enable us to promote Walker Bay as sustainable
ecotourism destination.
As citizen scientists on this project, you will help to
collect data that will lead to critical scientific research,
management and conservation efforts.
Assess the effectiveness of using photo identification
software on Dark shysharks, Brown shysharks, Puffadder
shysharks, Leopard catsharks, and Spotted Gully Sharks. All
sharks that are sampled through the angling survey will be
photographed and uploaded into a database. This noninvasive technique has been successful in identifying
individuals from other shark and ray species, such as whale
sharks and manta rays (eg. Meekan and Cappo 2004; Meekan
et al 2006, Malcolm et al 2007; Brooks et al 2011; Bond et al
2012). If the technique is successful, we will launch a
regional citizen science project where divers and fishermen
can send in photos of sharks. This will help us assess shark
distribution and seasonal pattern along the coastline.
RESEARCH AIMS
To date there is no formal assessment of the shark, ray and
fish species that live in Walker Bay. We aim to document
which species are present in Walker Bay and assess whether
certain patterns or trends are displayed in the shark
populations. The research team has several objectives,
including:
Assess the species diversity and abundance of shark and fish
species across different habitats in Walker Bay. Investigate
the population size of individual species and how they use
their habitats. This objective will be addressed using two

HOW YOU WILL HELP
• Aquaria and Touch tank maintenance and care:
You will assist with feeding the sharks in the tanks
at the research facility. You may assist in collecting
organisms for the facility touch tank. You will assist
project staff (from shore) with catching small demersal
sharks using snorkel gear and/or collecting shark egg
cases with growing baby sharks inside for our in-house
shark nursery.
As a volunteer on this expedition, you will be trained to be
involved in some or all the following research activities:
• Baited remote underwater video surveys (BRUVs)
deployment: You will accompany project staff to
deploy and retrieve BRUV rigs from a research vessel
and/or shore throughout the study sites in Walker Bay.
We will lower the BRUV rig into the water using a rope
and float system. Environmental parameters, such as
water depth, sea surface temperature, salinity, pH,
visibility, ocean current, wind speed and direction, and
habitat type will be recorded by the volunteers during
each sampling period.
• Shark Morphometric study: The project team is
currently re-evaluating a taxonomic key to assess
detailed measurements of endemic catsharks to
determine whether these measurements will assist
in species identification. You will assist by taking
detailed measurements on live sharks in our tanks.
• Baited remote underwater video surveys (BRUVs)
analysis: Back at the lab, you will download the video
and analyze the footage obtained from the BRUVs with
one of the project staff. This will involve counting the
number of sharks and other animals seen on the video
footage. You will be trained on how to identify local
shark and marine animal species.
You may also participate in one or more of the following
activities based on research needs and weather conditions:
• Eggcase hunts: You will work with one of SASC's
project partners, Whale Coast Conservation, in
assisting on eggcase hunts. Earthwatch teams will walk
along local beaches, document and collect eggcases
from sharks, skates and rays that are found on the
beach. This will help us determine which species are
found along certain beaches in the area.'
• Shark surveys: You will be present during each fishing
survey for shark species, assisting the trained staff
through the entire process. You will help to record
data, take length measurements, obtain a small fin
clip for later genetic analysis, and tag sharks.
• Shark Education and Outreach: SASC is passionate
about sharing research and conservation knowledge
with the public. The SASC laboratory is open to the
public and offers tours of the facility. Tours of the
facility are led by SASC staff. SASC regularly invites
school groups, white shark cage diving volunteers and
other community members to the facility. You may
assist with public education and outreach events.
• Photo identification: You will take photographs of all
sharks caught through the scientific angling surveys.
We may catch additional sharks and place them in our
holding tanks in the SASC facility. These photos will be
uploaded into our database to later be analyzed with
software to see if we can identify individuals by their
unique patterns. You will upload photos and data such
as tag number, sex, and other scientific measurements
into the database.

POTENTIAL HAZARDS
DISCOVERING SHARKS IN SOUTH AFRICA
HAZARD TYPE
ASSOCIATED RISKS AND PRECAUTIONS
Transportation
Teams will travel on public, paved roads in good condition, but risks inherent in road travel still apply.
All volunteers will have a seatbelt and must use it whenever the vehicle is in motion. Only qualified field
staff will operate vehicles.
Shark handling
Volunteers will be briefed on shark handling and procedures and the start of each team to minimise
injury to volunteers and sharks. All project staff have extensive shark handling experience from several
years up to a decade. Project staff will remove hooks from sharks mouths and conduct all the research
and shark handling from the pectoral fins to the mouth.
Personal Security
Hermanus is a generally safe region for travelers; however, do not leave valuables unattended in public
areas, and do not walk alone or at night. Use taxis services at night to get around. Volunteers will be
briefed on arrival about safety precautions and no-go zones.
Swimming
Swimming and snorkeling may be optional activities on your team. The area is directly in front of the
SASC office. Weather and sea conditions will be assessed by project staff before allowing any person to
enter the water. There is no lifeguard on duty.
Sun exposure
and heat
All volunteers will be briefed on sun safety. It will mandatory to bring hats, sunglasses and T-shirts and
footwear for all outdoor fieldwork. Length of field trips may be adjusted according to temperature and
sunlight exposure. Volunteers will be reminded to drink sufficient water.
Animals and insects
Sharks, jellyfish, sea urchins, and stingrays are all risks present when swimming, snorkeling, or wading
in the area. Volunteers will be trained to identify dangerous marine species and to avoid them. Protect
your feet by wearing shoes or booties, and by watching where you step. Mosquitos can be present at
night, during February teams.
Disease
Volunteers should consult their travel doctor prior to travelling and ensure immunizations are up to date
(tetanus etc). Malaria is present in South Africa, however it is restricted to a small area near the border
of Mozambique and it is not near to the research area, therefore malaria medication is unnecessary
unless volunteers plan to travel to other areas. A yellow fever vaccination certificate is required for
travelers travelling to and from infected countries but yellow fever is not present in South Africa.
Routine vaccinations (e.g. Hep A, B, should be up to date). South Africa has one of the highest rates
of HIV/AIDs in the world, so volunteers should be wary of blood or bodily fluid contact. Tap water is
considered potable in Hermanus, Cape Town and major cities but bottled water should be drunk when
travelling to remote areas.

SAFETY
HEALTH INFORMATION
PROJECT VACCINATIONS
REQUIRED: If traveling from countries or regions where
yellow fever is endemic, you must have a certificate of
vaccination. You may need to present this certificate
when you arrive in country.
RECOMMENDED FOR HEALTH REASONS: Typhoid,
Hepatitis A, Hepatitis B
EMERGENCIES IN THE FIELD
Accommodations and vehicles all have first aid kits. In the
event of a medical emergency, the Earthwatch scientists
will administer first aid, and depending on the seriousness
of the injury or condition, either take the volunteer to the
hospital using one of the project vehicles (always available)
or call emergency services by cellphone. While in the field,
the scientists will carry portable two-way radios and each
will carry a cell phone for emergency communication. If a
volunteer has to leave the expedition early for emergency
reasons, the Earthwatch scientists will determine the most
appropriate form of transport to the airport (either one of
the project vehicles or ambulance).
For emergency assistance in the field, please contact
Earthwatch’s 24-hour emergency hotline number on the last
page of this briefing. Earthwatch is available to assist you
24 hours a day, 7 days a week; someone is always on call
to respond to messages that come into our live answering
service.
IMMUNIZATIONS
Please be sure your routine immunizations are up-to-date
(for example diphtheria, pertussis, tetanus, polio, measles,
mumps, rubella and varicella). Medical decisions are the
responsibility of each volunteer and his or her doctor, and
the following are recommendations only. Visit the Healix
Travel Oracle website through the “Travel Assistance and
Advice” page in your Earthwatch portal, cdc.gov or who.int
for guidance on immunizations.

research and conservation projects around the world for the past decade. Australian born, she has been
blessed enough to work with sharks and other marine animals and communities in amazing locations
such as the Bahamas, US, Philippines, Mexico and South Africa. She has worked with some amazing and
threatened species, such as giant tiger sharks from 800ft on bottom of the Gulf Stream, pregnant lemon
sharks moments before they gave birth, critically endangered smalltooth sawfish, and her new personal
favorite: the endemic catsharks found in South Africa. Before working with SASC, Kat was the Manager
and Assistant Manager at the world famous Bimini Biological Field Station (Sharklab) in Bimini, Bahamas
for four years. Other than sharks, Kat's greatest love is science and strongly believes in science based
conservation and management for sharks and rays.
EARTHWATCH SCIENTIST Meaghen McCord is the founder and director of the South African Shark
Conservancy (SASC). Meaghen founded SASC in 2007 after identifying a need for research and
management of commercially exploited shark species in South Africa. She has an MSc in Fisheries
Science from Rhode University in Grahamstown, South Africa and her BSc. in Marine Biology from
Dalhousie University, Canada. Meaghen has an extensive background in shark research within South
African Africa (South Africa and Tanzania) and in her home country of Canada. Her greatest moment in
the field was leading the expedition that lead to the scientific discovery of bull sharks in the Breede
River, South Africa. This discovery helped rewrite existing literature on the species, describing a new
maximum size (four meters total length) and previously undescribed habitat. Since this discovery, she
has conducted four years of research on bull sharks in the river, including groundbreaking large-scale
movement studies using satellite telemetry. Meaghan McCord is a current member of the Sub-equatorial
African region International Union Conservation of Nature (IUCN) Shark Specialist Group.
EARTHWATCH SCIENTIST Tamzyn Zweig serves as the principal investigator for the South African
Shark Conservancy’s Recreational Fisheries research project (RecFish SA) and also helps manage
SASC's operations. As part of SASC's RecFishSA, Tamzyn has conducted fisher training workshops around
Southern Africa and has tagged over 1000 sharks and rays at fishing competitions. Tamzyn has a National
diploma in Fisheries Resources Cape Peninsula University of Technology, South Africa, in Fisheries
Resource Management.
NOTE: All Principle Investigators will be present for all the Eathwatch teams, although their roles and
participation may vary between teams.
