Whales

Whales face many threats to their welfare, health, and their existence. The main cause is commercial hunting and pollution. Chemicals and pesticides can poison their internal systems, while discarded rubbish like nets, plastics or fishing lines can strangle the animals to death. Whales are, just like dolphins, highly acoustic mammals. Noise caused by coastal developments and industrial activities can disrupt whales. Tourism also effects whales. They can feel very harassed, especially when they are breeding and calving.

When chemicals pollute the oceans, the food of whales also gets polluted. Female whales then pass these pollutants directly on to their young through their milk, which can result in death or disability. These pollutants also cause the lowering of the whale's resistance to disease. This means they are more likely to die from diseases.

Commercial as well as scientific whaling by countries as Japan and others remains a huge threat to the survival of certain whale species.

Proactive conservation of New Zealand blue whales - Researchers have developed a method for forecasting the locations where a distinct population of New Zealand blue whales are most likely to occur up to three weeks in advance.
‘Whoop’ – new autonomous method precisely detects endangered whale vocalizations - One of the frequently used methods to monitor endangered whales is called passive acoustics technology, which doesn't always perform well. In the increasingly noisy ocean, current methods can mistake other sounds for whale calls. This high 'false positive' rate hampers scientific research and hinders conservation efforts. Researchers used artificial intelligence and machine learning methods to develop a new and much more accurate method of detecting Right whale up-calls -- a short 'whoop' sound that lasts about two seconds.
Warming Atlantic drives right whales towards extinction - Warming oceans have driven the critically endangered North Atlantic right whale population from its traditional and protected habitat, exposing the animals to more lethal ship strikes, disastrous commercial fishing entanglements and greatly reduced calving rates. Without improving its management, the right whale populations will decline and potentially become extinct in the coming decades, according to a recent report.
