Restoring Coral Reefs in Bali

Please test for COVID-19 before traveling to your expedition; do not travel if you have tested positive, and call Earthwatch right away for the next steps. Visit earthwatch.org/covid-19 for more information on how you can help reduce the risk of COVID-19 impacting your expedition.

The small village of Kubu in northern Bali is home to a large community of fishermen who rely on healthy coral reefs to serve as a habitat for fish species. Previously, these reefs were exploited due to unsustainable fishing practices that degraded the coral and decreased the number of fish. Today, the reefs are part of a locally established Marine Protected Area (MPA) that helps to safeguard them by preventing fishing and other human activities. These protections have enabled the coral communities to recover, and the spillover of fish that wander outside the MPA is supporting the local fishers. The fishers and the community now recognize the importance of the protected area to ensure fish populations stay healthy and have been following the no-take rules of the MPA. However, the reefs face other pressing threats. According to the 2022 IPCC report, warmer and more acidic waters will devastate coral reefs worldwide. Coral reefs are essential not only because of their ability to maintain the biodiversity of the world’s oceans but also because of their beneficial role for humans. Reefs provide local communities with food, storm protection, and revenue through tourism. While artificial reefs won’t completely replace the benefits of natural reefs, implementing them in strategic locations could enhance food security and prevent marine ecosystems from collapsing as climate change degrades existing natural reefs. 

The nonprofit North Bali Reef Conservation (NBRC) has implemented approximately 13,000 artificial reefs in the waters off the shore of Kubu since 2016. These reefs are made from a mixture of cement, calcium carbonate, and sand and are made to mimic the habitat provided by natural reefs. On this project, you’ll investigate the extent to which artificial reefs can mimic the natural communities, ecosystem services, and socio-economic benefits of coral reefs. You’ll snorkel or scuba dive* over both artificial reefs and natural reef communities to conduct coral surveys, camera work, and fish community surveys to assess the communities’ biodiversity, identify predatory fish, calculate the biomass of grazers, and sample nutrient levels.

Coral reefs are very sensitive to the suite of environmental threats facing the world’s oceans⁠— from climate change to overfishing to habitat destruction. This project will help answer critical questions about how artificial reef structures can help combat ecological and economic losses, including food instability, as natural reefs deteriorate.

*Note: Certification is required for participation on scuba teams. See the Essential Eligibility Requirements in this document for detailed requirements.

The main goals of this project are to:

1. Assess the development of ecological communities on artificial reefs and monitor the time until these communities become stable;
2. Compare stable, established communities on artificial reefs to nearby natural reefs and determine the connectivity of the artificial reefs to other ecosystems;
3. Compare the levels of organic carbon in sediment and assess the cycling of carbon through the community;
4. Estimate the abundance of functional groups on artificial reefs and assess the short and long-term roles of predators on overall abundance to determine if predators can affect the carbon budget of ecological communities.

As an Earthwatch volunteer, you will spend much of your time snorkeling or diving over coral reefs to assist in three main types of fieldwork: snorkel/dive surveys, video deployment, and data analysis.

Snorkel and Dive Surveys

You’ll snorkel (or scuba dive) over both artificial and natural reefs to record the coral, sponges, gastropods, and fish in quadrats on the reefs. You’ll record these data either on underwater slates or by taking photographs. These surveys will help monitor how quickly communities are established on newly introduced artificial reefs and compare communities on established artificial and natural reefs. You may also collect water and sediment samples at different points along the reef structures to help assess the available nutrients within the different communities.

Video Deployment

You’ll help deploy underwater cameras, known as remote underwater video (RUV), to monitor mobile marine animal communities. The RUV cameras will be placed near natural and artificial reef units. After 30 minutes, the cameras will be retrieved. The videos will be analyzed for the number of species and individuals recorded. This will help researchers to compare the biodiversity and community structure of natural and artificial reefs.

Data Analysis

After careful training, you’ll analyze the images taken along the reefs and identify the species present. You’ll also analyze videos to determine the number of species present.

You will spend portions of the first two days becoming familiar with core fieldwork and analysis techniques, including photoquadrat sampling and using and analyzing remote underwater videos (RUVs) to assess mobile reef communities. Other educational opportunities will be offered throughout the expedition, covering topics such as climate change and its impact on coral reefs, methods to restore coral reefs, ecosystem services associated with coral reefs, coastal management, and basic reef species identification. On some teams, there may also be opportunities to visit local university laboratories to see how some collected samples are analyzed.

While Earthwatch participants are the sole supporters of scientific data collection, NBRC hosts several volunteer groups that will likely overlap with Earthwatch groups, including those assisting with constructing and deploying artificial reefs or teaching English at the onsite school.

* Earthwatch will honor each person’s assertion of gender identity respectfully and without judgment. For both teen and adult teams, where logistics dictate single-sex accommodations or other facilities, participant placements will be made in accordance with the gender identity the participant specified on their Earthwatch Participant form and/or preferences indicated in discussions with Earthwatch.

BATHROOMS

Bathroom facilities include flush toilets and cold-water showers (hot water is unavailable). Toiletries are not provided but can be purchased at nearby shops.

ELECTRICITY

There is regular 24-hour electricity at the accommodations, and you will have access to outlets to charge cameras, cell phones, and other personal electronic devices. Indonesia uses the 2-pin socket (standard European plug); you should bring an adapter.

PERSONAL COMMUNICATIONS

Wi-Fi is available during downtime on personal electronic devices, though connectivity can be unreliable at times, given the site's remoteness. Cell phone reception in the area is generally good, and local SIM cards may be purchased for low-cost at the airport on arrival if desired.  

Please note: Personal communication with outsiders is not always possible during an expedition. Earthwatch encourages volunteers to minimize outgoing calls and immerse themselves in the experience; likewise, family and friends should restrict calls to urgent messages only.

DISTANCE TO FIELD SITE

The accommodations are a three-hour drive from the airport, and volunteer pick-up/drop-off is provided using 7-seater cars or minibuses. The accommodations are only a short walk from the research site and shops selling daily supplies. A vehicle and driver are always available onsite in case of emergencies. 

Some research trips may involve short boat rides (less than 15 minutes). The boats used are small traditional Indonesian fishing boats with outriggers. Generally, sea conditions are calm at the research site. If you are known to get motion sickness, we recommend bringing medicine as advised by your local medical professional. If you are on a diving expedition, you should check with a medical professional that any motion sickness tablets are compatible with diving.

FOOD AND WATER

A dedicated team of local chefs will prepare breakfast, lunch, and dinner for volunteers. Meals will be eaten communally at the accommodations and include local Indonesian and international cuisine. The communal eating space is outdoors (under cover of thatched huts) and hosts Earthwatch volunteers and other volunteer groups present at NBRC. Hot water is unavailable from the kitchen tap, but boiled water is provided for hot beverages. 

The following are examples of foods you may find in the field. Variety depends on availability. We appreciate your flexibility.

TYPICAL MEALS

• Breakfast: Pancakes, toast, french toast, egg selection, fresh fruit, fried banana, coffee & tea
• Lunch and dinner: Fried rice, fried noodles, pasta, redang (Indonesian slow-cooked meat dish that can be made vegetarian), gado-gado (salad with peanut sauce), soto (broth-based meat & vegetable soup), fried chicken, satay, noodle soups, potato wedges/ French fries, vegetable fritters, western style salad. Note: Red meat is not commonly on the menu.
• Beverages: Clean drinking water, coffee, and tea are available on-site for free. There is also a nearby canteen which sells other drinks and local snacks. 

SPECIAL DIETARY REQUIREMENTS 

Please alert Earthwatch to any special dietary requirements (e.g., diabetes, lactose intolerance, nut, other food allergies, vegetarian or vegan diets) as soon as possible, and note them in the space on your participant forms. 

This project can cater to various diets, including vegetarian, vegan, lactose-free, gluten-free, and Kosher. Soy and/or peanut allergies are difficult to accommodate. Peanuts, peanut oil, and soy are common in Indonesian cuisine; thus, it is impossible to guarantee peanut and/or soy-free food. 

GENERAL CONDITIONS

Please visit Wunderground.com and search for your project location for weather and region-specific information.

Volunteers must be at least 18 years of age and should not have a phobia of water or marine life. All participants must be able to:

• Comfortably swim 800m in calm, open water
• Dive/swim/snorkel two times a day for ~1–2 hours in areas where it is not possible to stand on the bottom
• Duck-dive to a depth of 4m for a maximum of 10–15 seconds 
• Utilize all equipment recommended or required by industry standards, including masks, fins, and snorkel 
• Maintain a seated, cross-legged, and upright position within a narrow-outrigger boat during transit, which can sometimes be bumpy. Although boat trips usually last less than 15 minutes, this can be uncomfortable for individuals with back and joint problems.
• Comfortable riding in a boat seated at the level of the deck without exterior supports. 
• Comfortable entering and exiting the boat from land and water, which includes stepping up onto the boat platform 1m off the ground and climbing up and down a ladder to enter and exit the water. 
• Walk short distances in sand or uphill with a light pack
• Stoop, bend or kneel multiple times during the day
• Spend long hours in the field in hot and sunny conditions
• Tolerate insect bites (mosquitos, no-see-ums, and coconut bugs) and tropical wildlife (including lizards, bats, and insects), and comfortable around free-ranging outdoor dogs (these are abundant around the research accommodations)
• Follow verbal and/or visual instructions independently or with the assistance of a companion.
• Take an active role in your safety by recognizing and avoiding hazards if and when they arise (including, but not limited to, those described in Earthwatch materials and safety briefings). Always comply with project staff instructions and recommended safety measures.
• Effectively communicate to the staff if you are experiencing distress or need assistance.
• Get along with a variety of people from different backgrounds and ages, often in close proximity, for the duration of your team.
• Be comfortable surrounded by a language and/or culture different from yours.

Additional Requirements for SCUBA Teams: 

To participate as a scuba diver on this project, you must meet the below additional requirements:

• Hold at least a PADI Advanced Open Water certification (or equivalent qualification from a recognized certification program) and supply a copy of such certification to Earthwatch 
• Must have completed at least one dive within the 12 months before participation or complete a refresher course at your own expense before participating in dive activities 
• Submit a signed Earthwatch Diver Medical Form before participation (this is in addition to the Earthwatch Participant Form)
• Provide proof of dive insurance (through DAN or equivalent)
• Comfortable diving for an hour at depths up to 18m (excellent buoyancy control is required), & able to monitor own dive data using a dive computer
• Lift 35 lbs. of equipment (for example, research equipment and/or dive gear) and carry it 200m to the shore entry point
• For boat-based dives, divers must be comfortable diving from a narrow outrigger boat, which necessitates entering/exiting the water using a ladder and putting on gear while in the water. 

EMERGENCIES IN THE FIELD

Field staff are equipped with mobile phones to communicate to and from the field. A vehicle and driver are always accessible in case of an emergency. 

Earthwatch has a 24-hour, 7-day-a-week emergency hotline number. Someone is always on call to respond to messages that come into our live answering service.

IMMUNIZATIONS & TRAVEL VACCINATIONS

Please be sure your routine immunizations are up to date (for example, diphtheria, pertussis, tetanus, polio, measles, mumps, rubella, and varicella) and that you have the appropriate vaccinations for your travel destination. Medical decisions are the responsibility of each volunteer and their doctor. Visit the Center for Disease Control and Prevention or the World Health Organization for guidance on immunizations.

If traveling from countries or regions where yellow fever is endemic, you must have a certificate of vaccination.

Rabies is present in Bali and can be transmitted by bats, free-ranging dogs, and other mammals. Free-ranging dogs are present at the project site and are prevalent in Bali. Pre-exposure vaccination does not eliminate the need for post-exposure medical attention and treatment. Still, it does provide additional protection against the disease in the event of a delay in treatment. The nearest medical facility providing post-exposure treatment for rabies may take two hours or more to reach from the project site, and the availability of vaccines can vary. 

Staying up to date with your COVID-19 vaccinations, including receiving booster doses, as applicable, is strongly encouraged.

TRANSPORTATION

Participants will be driven in a car from the rendezvous to the field site and sometimes to other activities. There is a risk of road traffic accidents. Only vehicles with seat belts will be used, and vehicles will only be driven by staff with an international or Indonesian license and approved by the PI. Drivers will practice safe driving practices, including limiting speeds to 40 mph on narrow mountain roads, cautious passing, and safe following distance. Participants will not drive under any circumstance. A cell phone and first aid kit will always be carried in vehicles. There will be no driving at night except in the case of an emergency. Participants will not drive or ride on motorbikes.

Small local fishing boats may be used for research activities. There is a risk of a boating accident and injury or drowning from falling overboard. Boats will be operated only by people approved by the PIs. Participants are required to wear personal floatation devices while aboard the boats. Boats will be equipped with appropriate safety equipment, including a throw ring, spare mobile phone, first aid kit, emergency oxygen kit (for SCUBA teams), emergency contact list, and life jackets for each person. Staff will brief participants on boating risks and precautions onsite, including proper protocols for entering and exiting the boat and donning any necessary dive/snorkel gear. Participants are advised to avoid dangling their arms and legs over the boat's edge, to hold onto the sides of the boat with both hands while in transit, and to take caution in the water when passing underneath the boat's outriggers to avoid head and other injuries. In the event of bad weather, the use of boats will be prohibited.

FIRE

Due to the climate and weather, there is a fire risk in the accommodations. All rooms are fitted with smoke alarms and fire extinguishers. A fire blanket is available in the kitchen. Participants are briefed on the procedure if there is a fire. Any electrical equipment participants use must be compatible with the electrical system (voltage/outlets abroad may be different).

ANAPHYLACTIC SHOCK/ALLERGIES

There is a risk of adverse allergic reactions while on the expedition, including from food, insect, or environmental allergens. Participants with known allergies must bring appropriate medications (at least two Epi-pens, antihistamines, etc.) in case of an allergic reaction. Participants who utilize Epi-pens must notify staff of their locations while fielding. Field staff will be briefed on dietary requirements through participant forms.

SNORKELING/SWIMMING

Snorkeling is a physically demanding activity with inherent risks. Safety procedures are established to minimize the risk associated with snorkeling and outlined during the safety briefing before commencing the research activities. Duck dives will be limited to depths of 4m. Snorkelers must be able to use the appropriate technique to equalize as they duck-dive to avoid eardrum injuries and demonstrate the proper use of snorkeling equipment (including how to clear masks and snorkel, appropriate techniques for fin use and tips for safe breath holding). Before beginning fieldwork, participants’ abilities and stamina will be assessed in a shallow water environment. Personal flotation devices will be provided as needed, and PI or support staff will be in the water during all research activities. Swimming/snorkeling is only done in calm seas and with a buddy. Participants may do recreational swims, but they must swim with a buddy and inform a staff member of their route and expected return time. Participants must always remain within 5m of their snorkel buddy. 

DIVING

Scuba diving is a physically demanding activity with inherent risks. Safety procedures are established to minimize the risk associated with diving and should be followed closely. As with all diving activities, there is a risk of decompression illness (DCI). It can take up to 5 hours to arrange transport to the nearest hyperbaric chamber, details of which are provided in the Emergency Response Plan. Only participants in good health and with appropriate insurance, experience, and certifications can participate on Earthwatch dive projects. A divemaster supervisor is always present with divers, and project staff are first aid qualified. Participants are guided down and up slowly to prevent descending and ascending too quickly. A diver response plan is in place, and participants are advised on the protocol for a lost buddy. For activities split across more than one habitat type, a staff member trained in rescue diving will be at the surface to receive divers in distress. Oxygen is kept on the boat, and diver-down flags are employed for snorkeling and diving. Dives will not exceed a depth of 18m and will have a maximum time of one hour.

WATER ORGANISMS

Contact with fire coral is a potential risk during fieldwork and recreational swimming that causes a red, swollen, and potentially painful rash. During the initial safety briefing, participants will be trained about the appearance of fire coral and the impact of touching stinging organisms. Volunteers will be shown fire coral in the water when it is present. Protective gear, including a long-sleeved rash vest/legging or a wetsuit, is advised when working near fire coral, and gloves are to be worn when installing sediment traps on the benthic substrate. Participants should indicate if they have an anaphylactic reaction to insect stings and consult with their physician before participating to determine if a similar response might occur because of being stung by jellyfish or other marine organisms (small cnidarians can also be present in the water column and cause discomfort). There may also be venomous fish in the water, including stonefish, which cause extreme pain, headaches, and breathing difficulties if touched. Participants will be shown stonefish if present, and all staff are briefed on steps to treat envenomation.

SHARKS AND OTHER LARGE FISH

Shark and other large fish attacks are extremely rare but possible. Volunteers are to exit the water calmly if an animal acts aggressively.

HEAT

High temperatures and long days in the sun can cause sun exposure, dehydration, and sunburn. Participants should wear breathable clothes that cover their skin, reapply sunscreen throughout the day, and consistently drink water. Participants must communicate with field staff if they are not feeling well due to the sun and temperature.

HIKING

Falling, getting cuts, or twisting an ankle are potential risks while hiking. Although not a required part of the expedition, hiking may be offered during recreational time. Participants should wear proper footwear, have good endurance, and at times have protective clothing in the thick bush to avoid cuts and scrapes. Participants must inform research center staff of the route and expected return time. 

REMOTENESS/DISTANCE FROM MEDICAL CARE 

The nearest rural medical clinic is about a 10-minute drive from the project accommodations. However, it can take two hours or more to reach the nearest hospital and five or more hours to arrange transport to top-tier private hospitals in Denpasar—including the nearest facility with a hyperbaric chamber. Local emergency services, such as police and fire services, can be unreliable. If you have a chronic condition that could require immediate medical care (e.g., heart conditions, kidney problems, severe asthma, etc.), or if you are pregnant, please discuss your participation on this expedition with your physician. 

ANIMALS & PLANTS

Mosquitos, no-see-ums, and coconut (blister) bugs are present and bite. Mosquitos in Bali can carry various diseases, including Japanese encephalitis, malaria, Zika, dengue fever, and chikungunya. Participants especially sensitive to insect bites should not attend this project. Participants should bring insect repellent and wear long-sleeve shirts and long pants during the evening hours. Participants are advised to keep doors and windows closed during the early morning and evening hours. Domestic animals, including semi-stray dogs, are present in the camp. Participants should not approach or touch any domestic animals, including dogs, cats, chickens, ducks, or any pet in the camp or town. There is also the potential risk of coconuts falling from the trees. Trees are regularly maintained, but participants should not stand under coconut trees whenever possible.

CULTURE

In entering a new community with a different culture than your own, there is a risk of offending the local culture and beliefs. Participants should learn about the local culture ahead of time and will be advised on behaviors that may offend local people. Participants should cover their shoulders and knees when visiting local public areas, including the beach, temples, and shops. Beach wear should be modest.

ENVIRONMENTAL HAZARDS

The monsoon season runs from November to March. Earthwatch expeditions will not be scheduled during monsoon season. Seismic activity, including earthquakes and tsunamis, is a concern throughout Indonesia. Bali also has active volcanoes, including Mount Agung, visible from the project site. Field staff will monitor local media and be vigilant for alerts of natural hazards. Participants are advised to monitor local media when traveling to stay informed of any alerts and to avoid dangerous areas.  

CRIME

Petty and opportunistic crime is a risk in Indonesian urban centers, including in the tourist centers of Bali. Participants are advised to keep valuables hidden and to avoid excessive drunkenness, illegal drug use, and overtly suggestive behavior. Participants should use reputable transport services while traveling in Bali and avoid using unmarked or freelance taxis. The dorms at NBRC are equipped with locking doors.

DISEASE

Diseases present in Indonesia include Japanese encephalitis, malaria, Zika, dengue fever, chikungunya, leptospirosis, schistosomiasis, rabies, measles, hepatitis, typhoid, cholera, tuberculosis, avian/bird flu, and hantavirus. Travelers’ diarrhea is common in visitors to Bali. Participants should speak with their medical care provider or a travel health provider, take appropriate precautions, and have appropriate inoculations and up-to-date immunizations, including tetanus. Ample potable/treated water will be made available for consumption. Participants are advised to be vigilant in using insect repellent and mosquito nets and wear appropriate clothes. 

Rabies is present in Bali and can be transmitted by stray dogs, bats, and other animals. Free-ranging dogs are prevalent at the project site. Whether you have been vaccinated or not, always avoid loose and stray dogs. The pre-exposure vaccination does not eliminate the need for post-exposure medical treatment. Still, it does provide additional protection against the disease in the event of a delay in treatment. In addition, bites or scratches should be immediately and thoroughly washed with soap, clean water, and a topical povidone-iodine solution or ethanol. If you feel ill once you return from your trip, inform your doctor that you have recently returned from a tropical region.

Please see the US Centers for Disease Control and Prevention (cdc.gov) or the World Health Organization (who.int) websites for more information on these diseases and how to avoid them.

COVID-19 DISEASE RISKS 

COVID-19 remains an evolving risk to communities and individuals around the world.

Earthwatch strongly encourages you to stay up to date with your vaccinations, including receiving booster doses if available, and to continue to limit your exposure before your program, such as wearing a mask during travel and frequently washing your hands. Persons with a higher risk of severe illness from COVID-19 should consult with their healthcare provider before participation. 

If you, or another person on site, display symptoms of illness or test positive for COVID-19, you may be required to wear a mask, test for COVID-19, seek medical advice, isolate/quarantine on- or off-site, cease or limit participation in program activities, and/or take other precautions. If local conditions or recommendations from authorities change, additional requirements may be implemented. 

If you must isolate or depart from a program due to COVID-19 or other illness, you will not be entitled to a refund of the contribution for the program, nor any expenses resulting from your participation in the program or a disruption of your travel plans. We strongly encourage you to purchase travel insurance that will cover this eventuality.

RENDEZVOUS LOCATION

Ngurah Rai International Airport (also known as Denpasar International Airport), Bali, Indonesia 

* Earthwatch will provide additional information to meet your team. Please do not book travel arrangements such as flights until after you have received further information from Earthwatch.

ABOUT YOUR DESTINATION

Earthwatch strongly recommends that travelers investigate their destination before departure. Familiarity with the destination’s entry/exit requirements, visas, local laws, and customs can ensure smooth travel. The U.S. Department of State's Traveler’s Checklist and Destination Guides are helpful resources. For LGBTI travelers, the U.S. Department of State's LGBTI Travelers page contains many useful tips and links.

COUNTRY AND PROJECT ENTRY REQUIREMENTS

You are responsible for reviewing and abiding by your destination's entry/exit requirements.

Entry visa requirements differ by country of origin, layover, and destination and do change unexpectedly. For this reason, please confirm your visa requirements at the time of booking and again 90 days before travel. Please apply early for your visa (we recommend starting six months before the start of your expedition). Refunds will not be made for volunteers canceling due to not obtaining their visa in time to meet the team at the rendezvous. You can find up-to-date visa requirements at the following website: <a href="https://www.travisa.com/">travisa.com.</a>

If a visa is required, participants should apply for a TOURIST visa. Please note that obtaining a visa can take weeks or even months. We strongly recommend using a visa agency to expedite and simplify the process.

Important: While many nationalities may travel to Indonesia for short-stay tourism with a visa-on-arrival, our local partners have made us aware of a new visa requirement mandating that any individuals traveling to Indonesia specifically to conduct volunteer activities must obtain a B211A Social Visit Visa before arriving in Indonesia. Local immigration authorities are strictly enforcing this specialized visa requirement—so it is important that all Earthwatch participants comply. Registered participants can find detailed instructions for obtaining the B211A visa within their Expedition Logistics Document. The fee is USD 230, and the application process is facilitated on behalf of all participants through our local non-profit partner—North Bali Reef Conservation.
