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.<\/p>\n\n\n\n

Quick growth in the population of algae in freshwater or marine ecosystems, as a result of excessive nutrients in the environment. \u00a0It 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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

A learned, cooperative feeding strategy that involves a group of whales. Humpback whales and Bryde\u2019s whales use this strategy. The 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 \u201cnet\u201d of bubbles and stay trapped. Then the whales swim with their mouths open through the trapped fish, and efficiently feed themselves.<\/p>\n\n\n\n

The process of selecting a course of action from available alternatives based on the analysis of information, estimation of probabilities, and assigning values to anticipated outcomes.\u00a0A decision usually concerns a specific situation, for example, managers deciding on the number of animals that can be hunted in a region based on the available scientific data.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

Also known as divers\u2019 disease or the bends. It happens when a diving person or animal ascends to the 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, pain, and even death.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

\n\t\t\t\n\t\t\t\tMarine protected areas\t\t\t<\/a>\n\t\t<\/h3>\n\t\t\n

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 \u201cspills\u201d 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.<\/p>\n\n\n\n

\n\t\t\t\n\t\t\t\tMining\t\t\t<\/a>\n\t\t<\/h3>\n\t\t\n

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\u2019s 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.<\/p>\n\n\n\n

The process of sea water becoming more acidic (lower pH value) caused by the excess of atmospheric carbon dioxide (CO2<\/sub>) 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.

Excessively harvesting a natural resource faster than it can replenish itself through natural processes.

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.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

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.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

The current way of naming species was developed by Carl Linnaeus and it is called binominal (binary) nomenclature. According to it, each species name consists of two parts: the first is the name of the genus to which the species belongs and the second name distinguishes the species within the genus.  <\/p>\n\n\n\n

Also known as \u201cearless\u201d seals, true seals belong to a group of pinnipeds that have ear holes, but lack an external ear flap. While sea lions belong to the group of pinnipeds, they are not true seals because they have ear flaps. Grey seals instead, are true seals.<\/p>\n\n\n\n

Large raised \u201cbumps\u201d 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.
