Marine mammals use sound for communication, navigation, and hunting. Human activities like shipping, fishing, oil and gas exploration and marine military activities, marine renewable energy production, and recreational water activities produce noise and can disrupt marine mammals. These disturbances can interfere with the animals’ natural behaviours, like feeding, caring for their young, socialising, resting, and migrating. As a result, individual fitness and survival rates may decrease.

The oceans are filled with sounds, both natural and human-made. Natural sounds include those generated during earthquakes or produced by marine life, such as marine mammals, fish, and some invertebrates. Noise from human activities, known as anthropogenic noise, also contribute to the ocean’s soundscape. Sound can be classified as continuous—low in intensity but more constant, like noise from shipping (motors and sonar) and industrial activities—or impulsive—high in intensity and shorter in duration, such as explosions, pile-driving, seismic exploration, and military sonar activity. Scientists study underwater noise using spectrograms.

The underwater soundscape of the Arctic is becoming increasingly noisy as a consequence of climate change. As the sea ice decreases and thins, previously inaccessible areas are opening up to human activities, contributing to increased noise pollution [1]. This noise can significantly disrupt marine mammals, particularly species that are sensitive to sound, such as narwhals. Research has shown that narwhals, typically deep-divers, reduce their foraging activity and shift to shallower depths when exposed to human-made noise [2]. Other deep-diving species, like beaked whales, may react negatively to impulsive noise causing them to resurface too quickly and suffer decompression sickness [3].

Did you know that...

  • For the average human ear, only sound signals between 20 Hertz and 20,000 Hertz are audible. In contrast, the range of sounds and signals emitted and detected by marine mammals spans a much broader spectrum, from 7 Hertz to 160,000 Hertz, showing the higher sensitivity of marine mammals to noise.
  • Disturbance may affect individuals and be a welfare issue, but it may also have effects at the population level.
  • While noise is still a challenge for management, once we stop emitting noise, it will be gone immediately, unlike other threats like pollution that take decades to degrade and thus, to mitigate.

Discuss

How can we balance the economic benefits of activities like fishing and tourism with the need to protect marine mammals from disturbance?

Zooplankton

Animals, that live in the water column but cannot actively swim against currents. While most zooplankton are tiny, like copepods, krill, and the larval stages of larger species, some are much larger, such as salps and jellies. Many species of zooplankton spend daytime in deeper water (avoiding light and predators), moving towards the surface to feed at night, in a process called vertical migration.

Whelping

Giving birth. This term is used for carnivorous species, including pinnipeds. Several species of seal travel to specific whelping grounds (or patches) to give birth.

Tubercles

Large raised “bumps” on the edges of humpback whale flippers. These where shown to make their flippers more hydrodynamic, which helps explain how humpback whales are so agile. Engineers have copied the tubercle effect to improve aerodynamic and hydrodynamic technology.

Subsistence whaling

Not intended to maximise profit but to fulfil the subsistence needs of an individual or community. Compare with commercial whaling.

Sonar beam

Sound energy that is emitted in a cone or fan shape from the sound source, to detect objects the sound will bounce back from.

Sonar tag

An sensor that uses sonar technology to detect what is in the immediate environment of the animal on which it is placed. Putting a sonar tag on a seal, for instance, would reveal the size and movements of the prey it targets, whether it interacts with human-made objects, and so on.

Sonar

Technology that uses sound to detect objects and navigate, usually in the water. It uses the same principles as echolocation in animals, sending out waves of sound that bounce back when they hit an object. Vessels may use sonar to ”see” changes in seafloor depth or find schools of fish. Naval sonar is used to detect submarines.

Seismic exploration

A way to map what lies underground using sound waves and how they are reflected or absorbed by different materials, usually to detect deposits of oil and gas. To explore what is under the seafloor, a ship blasts compressed air (using what is called a seismic airgun) into the water, creating loud sound waves. Part of the sound is absorbed by the different materials underneath the seabed, while the rest is reflected back towards the ship. The shape and intensity of the sound waves that returns indicates what type of materials there are at different depths.

Real-time whale detection system

A setup that detects the presence of whales in a given area at the time they are there and alerts users about them immediately, rather than collecting data for several hours/days/months to be processed later.

Quota

A fixed maximum quantity of a resource that each person or group is allowed to take. For instance, the maximum number of minke whales that Norway and Iceland can hunt each year is their minke whale quota.  

Protection

Efforts and regulations to mitigate harmful impacts on the environment (such as laws that prevent pollution). Protection goes hand in hand with conservation, which refers to maintaining biodiversity through sustainable resource use. In some cases, the only way to protect an ecosystem is through preservation, which forbids humans from using it as a resource. In the context of marine mammal hunting, a protected species means that hunting it is forbidden.  

Plankton

Organisms that float in the water column without strong swimming abilities, i.e., that cannot propel themselves for large distances or against currents. Planktonic life includes phytoplankton, which lives in the surface layers where there is light to photosynthesise, and zooplankton, which can live throughout the water column.

Pile-driving

Hammering long columns of steel, wood, or concrete into the seafloor to create supports for structures like piers, bridges, and wind turbines.

Phytoplankton

Small (generally microscopic) bacteria, protists, and plants that live floating in the water column rather than attached to a surface like the seabed. The base of all marine food webs.

Navigation

Planning a route and moving towards a target while avoiding obstacles.

Larva

(Plural: larvae) Intermediate stage in the development of many animal species, between egg and adulthood. Larvae are often a very different shape from the adults of their species.

Simplified crab life cycle, showing two different larval stages, the zoea and megalopa, that take place before the juvenile and adult phases.

Kelp forest

Important underwater habitats in arctic and subarctic waters. They are large congregations of kelp—a type of brown algae that grows many metres tall—that provide food and safety for many marine species and are recognised as one of the most productive and dynamic ecosystems on Earth.

Invertebrate

Any animal that doesn’t have a backbone (vertebral column), such as insects, molluscs, worms, sponges, and many, many more. Animals that do have a backbone are called vertebrates—and that list is much shorter.

Intensity (sound)

A sound source in the water causes movement of the water molecules with a certain amount of energy that flows away from the source—this is how sound travels. Acoustic intensity is the amount of this energy that passes through another area of water, in other words, how loud the sound is when it reaches you or another object.

Head-butting

Aggressive or play behaviour in which two animals hit each other head-to-head. This is often seen in goats, sheep, and deer.

Fission-fusion society

A form of social organisation in which groups merge and split up depending on the time of day, year, or activity. Members of a fission-fusion society have few or no stable connections with other members, that is, they don’t always stay together.

Evolution

Changes in the characteristics of a species through the process of natural selection. Organisms with the best suited adaptations for their current environmental conditions pass on their genes to the next generation, and this can often lead to very specialised abilities and behaviours.

Ecology

“The study of relationships between living things and their environment” (British Ecological Society). Marine mammal ecology studies the behaviour, movement patterns, distribution, and abundance of these species as it is influenced by the physical characteristics of the ocean, the availability of food, and human activities.

Detritus

Non-living biological material (organic matter) that is created from decomposing organisms, discarded animal parts like exoskeletons, or feces. In the ocean, detritus sinking slowly through the water column is called marine snow, which is crucial for transporting nutrients from surface waters to deeper zones.

Crustaceans

Primarily aquatic group of arthropods (often with shells or “crusts”), which includes crabs, shrimp, krill, and barnacles, among many others.

Bradycardia

Extremely slow heartrate. Slowing down the heart and pumping blood slower through the body is a way to conserve oxygen when an animal is diving for a long time. Blue whale hearts can beat as slow as two times per minute (Goldbogen et al. 2019)!

Bottom trawling

Using a type of trawl that is dragged along the sea floor to collect benthic species. Because the net is weighted down with heavy beams, this fishing method often breaks or crushes plants and animals that are attached to the seabed.

Biodegradable

A material that can by broken down and returned to the environment through natural processes, such as being consumed by fungi or bacteria.

Benthos

In marine ecosystems, all the organisms that live on, in, or near the sea floor (benthic zone). These often have benthic adaptations, such as flattened bodies or the ability to withstand huge pressure.

Autotroph

Organisms that make their own food through photosynthesis or chemical synthesis, also called primary producers. Plants, algae, and many bacteria, for instance, are autotrophic.

Overgrazed kelp forest

 Sea urchins are one of the species that feed on kelp. When the population of sea urchins grow uncontrollably, due to their predators being removed from the food web, they overfeed on these forests and cause them to disappear, destroying the entire ecosystem. Once the kelp is gone, it is replaced by other algal species that don’t have the same function as kelp.

Wildlife

Animal and plant species that have not been domesticated. It also includes all the organisms that live in their environments without being introduced by humans.

Stress

Biological response to environmental pressures or threats that disrupt the balance in the body. It triggers adaptive behaviours and physiological changes aimed at survival. It is a survival mechanism that helps animals respond to and cope with environmental challenges, but chronic stress can be harmful.

Seafloor destruction

The physical and ecological damage or degradation of the ocean floor caused by natural events or human activities, leading to the loss of marine habitats, biodiversity, and ecosystem functions.

Parasite

An organism that lives in or on a host organism of a different species, and uses that organisms’ resources at the detriment of the host organism. Tapeworms are one well-known kind of parasite.

Overfishing

Catching fish at a higher rate than the population or stock has a chance to recover. To simplify, there are not enough mature adults that can reproduce and keep the population healthy. Overfishing leads to decreases in population numbers and can even lead to crashes of entire fishing grounds.

Ocean warming

The process of rising sea water temperatures caused by the Earth’s atmosphere trapping more heat due to greenhouse gas emissions, with the oceans absorbing most of this excess heat. Ocean warming can have catastrophic consequences on all life, both in the water, but also on land.

Schematic visualisation of ocean warming © Copernicus Marine Service

Ocean acidification

The process of sea water becoming more acidic (lower pH value) caused by the excess of atmospheric carbon dioxide (CO2) dissolving in the water and forming acid. The levels of carbon dioxide are rising due to different human activities, such as burning fossil fuels, deforestation, and industrial processes. Ocean acidification causes issues for all life in the ocean.

Nutrient

A substance found in food, such as proteins, sugars, fats, or vitamins, that provides the body with the necessary fuel and materials to grow, develop, and maintain health.

Nursing

The act of a female mammal feeding milk to a baby or juvenile. The female’s mammary glands produce milk that is rich in all the nutrients that the offspring needs for optimal growth and development. The milk content differs from species to species, depending on what the young need for development. Pinnipeds always nurse on land or ice, while cetaceans nurse underwater.

Mitigation

The action undertaken to reduce or minimise the severity, seriousness or negative consequences of something. For example, different rules and regulations made to help fight the negative effects of climate change.

Mining

The process of digging a valuable material, minerals, from the Earth. Mining can be surface or underground. In surface mining, the minerals are extracted from near the Earth’s surface and this type can be very destructive to surrounding area. Underground mining consists of taking minerals from deep under the surface by digging or blasting tunnels. Deep sea or seabed mining refers to extracting minerals from the ocean floor.

Guideline

A general rule, principle or a piece of information. Suggests or instructs on how an activity needs to be performed, or how people are expected to behave in a given situation.

Dredging

The mechanical process of removing sediment, debris, or other material from the bottom of bodies of water such as rivers, harbours, lakes, or seas. It is done to keep waterways deep enough for ships, support port construction, extract underwater resources like sand, prevent flooding by clearing blockages, and clean up polluted sediments. Dredging can harm marine ecosystems by destroying habitats on the sea floor, increasing water turbidity, and disturbing or displacing marine life. It may also release pollutants trapped in the sediment, affecting water quality and the health of nearby organisms.

Disturbance

An event or action that changes or interrupts the natural behaviour of plants, animals or the environment.  In this context we are talking about human activities that cause negative changes in the environment.

Cumulative impacts

The combined effects of multiple activities or environmental changes over time that, together, cause greater harm to a species or ecosystem than each would individually. They build up gradually, often leading to significant long-term damage that may not be apparent from any single action alone.

Biodiversity

All different plant and animal species that live in the same habitat. The level of biodiversity can be a good indicator of the state (health and stability) of the ecosystem.

Aquaculture

 Farming in the water, both fresh and sea, i.e., breeding, raising, and harvesting aquatic organisms, such as fish, shellfish, crabs, or algae for profit.

Quick growth in the population of algae in freshwater or marine ecosystems, as a result of excessive nutrients in the environment.  It is usually characterised by changes in the colouration of the sea depending on which species of algae have caused the bloom (red, brown or green). These blooms have a harmful effect on the environment and other species that live in the area: the limit the amount of light that penetrates the water surface, use up all the oxygen in the water and suffocate other organisms, and even produce toxins as a by-product of their metabolism.

Overexploitation

Excessively harvesting a natural resource faster than it can replenish itself through natural processes. For instance, using too much freshwater for agriculture can deplete aquifers because the water cycle takes longer to refill them; hunting too many blue whales in the 20th century dramatically reduced their global population because their reproductive rate is slow.

Moratorium

A temporary delay or suspension of activity, law or payment. In our context, the moratorium reefers to the cessation of the hunt of large whales in 1985 onwards. That means that since then, the member countries of the IWC have stopped whaling, with the exception of Iceland and Norway.

Global North

Global North and Global South are the terms used to group countries based on their defining characteristics with regard to socioeconomics and politics. More specifically, the Global North consists of the world’s developed countries, whereas the Global South consists of the world’s developing countries and least developed countries. The terms do not refer to the Northern and Southern hemisphere, as some of the countries of the Global North are located in the geographical south, and vice versa.

Beaked whales

Family of toothed whales counting 22 species. They are the least known of all whale species because they mostly stay in deep offshore areas, avoid boats, and are hard to identify. Almost everything we know about these animals, we learned from stranded individuals. They are named after their extended snout, and most species of this family only have one pair of tusk-like teeth that is only visible in males.

Monitoring

Activity that ensures that something is happening in accordance with rules and regulations. In the context of hunting, monitoring is conducted to make sure that animals are hunted in compliance with welfare standards, safety standards for the hunters, and that government guidelines for hunted stocks are being followed.

Marine protected areas

A marine protected area (MPA) is a clearly defined region established to conserve marine biodiversity, ecosystem health, and cultural heritage. As part of a globally connected network, MPAs help safeguard marine resources while ensuring the continued supply of essential ecosystem services. Effects of MPAs can be seen not just in the areas themselves, but also surrounding areas, as marine life “spills” over the boarders of the MPA increasing biodiversity and biomass in the areas around it. Not all MPAs have the same level of protection: while some are fully protected and nothing can be taken from there, others allow for some level of resource extraction.

Anthropogenic

Of human origin. Changes in the environment or pollution caused by human activities such as farming, mining, fishing, are called anthropogenic changes. Anthropogenic underwater noise is sound caused by ships, building marine infrastructure, sonar, and other human activities.

Sea ice

Frozen sea water. It covers part of the Arctic and Antarctic regions throughout the year, and also forms seasonally in some regions. It can be classified as (land)fast ice if it is attached to land or pack ice if it is not.

Bottom feeder

Animals that feed on other organisms that live on or near the bottom of a body of water.

Circumpolar

Distribution type where species occur over a wide range of longitudes, but only in high latitudes. That means that species can be found all around either the North or the South Pole. An example of species with circumpolar distribution is a polar bear.

Omnivores

All animals that eat both plants or phytoplankton and other animals.

Adaptive management

Adaptive management is a structured, step-by-step approach to improving resource management by learning from the outcomes of past decisions. It involves making decisions in the face of uncertainty, closely monitoring the results, and adjusting strategies over time. The goal is to reduce uncertainty and improve decision-making by continuously refining practices based on what is learned. It emphasises accountability and clarity in each decision-making step, allowing for flexibility and better long-term management of resources.

Secondary sexual characteristics

Physical characteristics that indicate the sex of the organism but are not directly related to reproductive system. They are developed later in life when organism reaches sexual maturity. Secondary sexual characteristics usually have a role in securing a mate and reproduction. Some examples are antlers in stags, peacocks’ long tail, tusk in narwhals, or hood of the hooded seals.

Different examples of secondary sexual characteristics

Lobtailing

A form of social behaviour of cetaceans where an animal lifts its tail fluke above the water and brings it down with force. The result is a big splash. They display this behaviour in order to call attention to other individuals.

Fitness

The ability of organism to survive and reproduce in the environment they are in.

Decompression sickness

Also known as divers’ disease or bends. It happens when a person or animal ascend to surface too quickly. Because of the sudden changes in pressure, the dissolved nitrogen in the blood gets released in the form of bubbles in the bloodstream and tissues and can cause different symptoms, such as fatigue, dizziness, neurological disturbances, pains…

Taxonomy

Branch of science that deals with identification, classification, and naming extant (currently living) and extinct (no longer living, fossils) organisms based on shared characteristics. The current way of naming species was developed by Carl Linnaeus and it is called binominal (binary) nomenclature. According to it, each name species consists of two names, the first is the name of the genus to which species belongs to and the second name distinguishes the species withing the genus.

Indigenous knowledge

A body of observations, oral and written knowledge, innovations, practices, and beliefs developed by Tribes and Indigenous Peoples through interaction and experience with the environment. It is applied to phenomena across biological, physical, social, cultural, and spiritual systems. Indigenous Knowledge can be developed over millennia, continues to develop, and includes understanding based on evidence acquired through direct contact with the environment and long-term experiences, as well as extensive observations, lessons, and skills passed from generation to generation (Guidance for United States Federal Departments and Agencies on Indigenous Knowledge).

Human activity

The role that humans play in the environment and ecosystems they are a part of. It includes all the intentional and unintentional effects on the environment.

The Arctic Council is as an intergovernmental platform dedicated to tackling the challenges faced by both Arctic governments and the Indigenous communities inhabiting the region. The Arctic Council is formed by eight member states, each with sovereignty over territories within the Arctic Circle: Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden, and the United States.

Bubble net feeding

A learned, cooperative feeding strategy that involves a group of whales. Humpback whales and Bryde’s whales use this strategy. A whales circle a school of small fish or swarms of krill they are hunting and start blowing bubbles. The fish are unable to escape this “net” of bubbles and stay trapped. Then whales swim with their mouths open through the trapped fish, and effectively feed themselves.

Survey

Generally, survey is a systematic method of collecting information or data. There are different types of surveys, one of them being abundance surveys. This term refers specifically to the assessment of the quantity and distribution of a particular species or resource within a specified area. These surveys aim to estimate population sizes, density, and trends over time. Abundance surveys are important as they as they help researchers understand ecosystem health, make informed management decisions, and monitor changes in biodiversity. Methods may include direct counts, sampling, and remote sensing techniques. One example of abundance survey is the NASS-North Atlantic Sighting Surveys.

Adaptation

“The natural process by which a living species becomes the best fitted for its environment. Adaptations are a result of natural selection’s acting upon heritable variation over several generations” (Gittleman, 2022). Organisms adapt in many different ways, their body structure, their physiology, the way they move through their environment, and even on a genetic and molecular level. For instance, the blowhole at the top of a dolphin’s head is an adaptation that allows it to keep swimming without slowing down to breathe by sticking its entire face out of the water.

Fin

A powerful burst of air, expelled from a whales blowhole, which creates a spray-like blow around the whale’s head. A whale’s spout can be used to recognise a whale species from afar. This is because each species, with their characteristic size and blowhole type, will have a different spout.

Spouts of different whales © GREMM

Population

A group of individuals of the same species living in a particular area at the same time that share a common genetic pool, allowing them to interbreed (Waples and Gaggiotti, 2006).

Vocalisation

The sounds that cetaceans make to communicate. There are several different sounds used during the vocalisations, such as clicks, whistles, and pulses. Clicks and pulses are generally used in echolocation, while whistles are thought to be used for communication within a group.

Insulation

A cover that prevents heat, sound, or electricity from escaping or entering.

Food chain

The sequence of transfers of matter and energy in the form of food from one organism to another.

Pinniped

Management area

The management area is the area at which the management is done for a given species. A species can have a wide distributional range and be impacted very differently by humans through this range. Hence its conservation status may vary between the areas. Management is therefore done not at the species level, but at the area level, which is relevant for that particular species.

Cetacean

Any member of an entirely aquatic group of mammals commonly known as whales, dolphins, and porpoises (Encyclopædia Britannica). Six species of baleen whales and 10 species of toothed whales are common permanent residents in the NAMMCO management area.

Minke whale body anatomy © Encyclopædia Britannica

Conservation

The attempt to make humans’ relationship with the environment sustainable while still extracting natural resources.

Abundance estimate

The quantification of the total number of cetaceans or pinnipeds within a certain population or geographic area. Repeating abundance estimate surveys over time in a specific area is an important tool to understand if the number of animals is growing or declining over time. This allows scientists and policymakers to make informed decisions about conservation strategies and management practices.

Management

The process of dealing with something in an effective manner.

Migration

The behaviour in which animals travel from one habitat to another habitat to cover different needs, such as finding better environmental conditions, search food or reproducing.
