Annual Humpback Whale Migration – East Coast Australia

Each year between April and November, Australia’s eastern coastline comes alive with the spectacular acrobatic displays of humpback whales. After a summer of feeding on krill in Antarctic waters, these charismatic animals migrate north to sub-tropical waters where they mate and give birth. And we are lucky enough to be able to easily spot them on their travels from our majestic coastline! Read on for more fascinating information about the migration and for FREE Humpback Whale Resources.

During their annual migration of up to 10 000 kilometres, humpbacks can easily be seen off the coast of New South Wales and Queensland.

The exact timing of the migration period can vary from year to year depending on water temperature, sea ice, predation risk, prey abundance and the location of their feeding ground.

Humpback Migration Route and Timing

The majority of humpbacks in Australian waters migrate north from June to August, and back towards the Southern Ocean from September to November.

Migration Grouping

Groups of young males typically lead the migration while pregnant cows and cow-calf pairs bring up the rear. Adult breeding animals form the bulk of the migration in the middle stages.

Humpback Whale Facts

  • Humpback whale length: 12- 16 metres
  • Humpback whale weight: up to 50 tonnes or 6 elephants!
  • Average birth weight of humpback: 2 tonnes
  • Birth length: 4-5 metres
  • Humpback whale gestation period: 11 months
  • Favoured birth temperature: 22-25 degrees
  • Origin of Humpback Whale name: the name comes from their very long pectoral fins and knobby looking head which looks a bit like a hump!
  • Easily tracked as identifiable by the unique markings on their tail fluke – so we can learn lots about them!
  • Humpback whale travel speed: up to 8 km an hour
  • Migration travel speed: humpback average only 1.6km an hour during the migration as they rest and socialise along the way
  • Humpbacks sing songs that may be heard hundreds of kilometres away
  • East Coast Australia’s most famous humpback whale is white and has an Aboriginal name, ‘Migaloo’ which means white fella.

The humpback whale is not the largest whale found in Australian waters but we reckon its’ the most iconic.

How oceans help fight Covid-19

There is no doubt that our health is intimately tied to the health of the earth and its’ oceans. According to UNESCO, our oceans not only help in the detection of COVID-19 but could also help combat it.

 

How oceans help detect Coronavirus

Bacteria found in the depths of the ocean are currently being used to carry out tests to detect the presence of COVID-19. The bacteria were identified years ago and have been used to diagnose other viruses such as AIDS and SARS.

 

How oceans could help treat Covid-19

 

 

In addition to diagnosis, many commonly used medicinal products already come from the ocean, including ingredients that help fight cancer, arthritis, Alzheimer’s and heart disease. The potential health benefits lie in the diversity of microbes found in the ocean’s hydrothermal vents. These are currently being researched as a potential treatment for Covid-19.

 

 

 

Our lives depend on healthy oceans (and a healthy planet) in many ways. Oceans cover nearly three quarters of the Earth’s surface; contain 97 per cent of the Earth’s water and support life on earth by providing oxygen and food to an astonishing range of ocean and non-ocean life.

 

 

How Can I Protect the Ocean?

Scientific research has concluded that we need to protect 30% of our blue planet by 2030 in order to safeguard the health of marine life and habitats. Yes, we need to put pressure on governments to take action and change policy but we can all do our bit to make a difference. In fact, working together we can all make a huge difference.

“Our actions over the next 10 years will determine the state of the ocean for the next 10,000 years.” Dr.Sylvia Earle, Marine Biologist & Conservationist

 

How you can take action to protect the ocean locally and internationally…

 

Local action to protect the ocean

 

  • Reduce your use of plastics: refuse, reduce, reuse, recycle
  • Reduce your carbon footprint and energy consumption: use public transport and turn off unnecessary appliances
  • Make sustainable seafood choices: check the label – is it ocean friendly?
  • Help take care of the beach: volunteer with an organisation such as Coolum Coast Care or simply pick up debris as you walk
  • Travel the ocean responsibly: be mindful of wildlife and never throw anything overboard
  • Campaign for change: support local campaign groups such as Coolum Coast Care and Great Barrier Reef Foundation to protect and rebuild marine areas
  • Educate yourself and your friends about oceans and marine life: the more you know, the more you’ll want to help ensure the health of the ocean – then share that knowledge to educate and inspire others.

10 Reasons Why We Depend On Our Oceans

Healthy, productive oceans are essential for food, jobs and economic growth. They also keep the planet cool – in more ways than one!

1. 50-70% of our oxygen – This oxygen comes from phytoplankton (tiny oceanplants that live close to the water’s surface and use sunlight and carbon dioxide to make food).

 

2. Absorption of carbon dioxide – About 30 per cent of carbon dioxide produced by humans is absorbed by our oceans, buffering the impacts of global warming.

3. Climate regulation – Oceans transport heat from the equator to the poles, regulating our climate and weather patterns.

4. Economic benefit and jobs for millions of people – Ocean-dependant businesses directly or indirectly employ over 200 million people worldwide.

5. Food for millions of people – Oceans serve as the world’s largest source of protein, with more than 3 billion people depending on the oceans as their primary source. Ingredients from the sea are found in surprising foods such as peanut butter and soymilk.

6. Breakdown and removal of waste and pollution

7. Marine transportation for world trade – Over two thirds of most developed countries’ trade involves some form of marine transportation.

8. The majority of life on earth – As over 70% of the Earth’s surface is underwater, it comes as no surprise that marine species outnumber those on land – an incredible 94 per cent of the Earth’s living species exist within the oceans.

9. Tourism, recreation and fun  – Fishing, boating, kayaking, diving, surfing and whale watching – the ocean provides us with many unique activities. Humans just love the beach and coastline!

10. Medicine: Many medicinal products come from the ocean, including ingredients that help fight cancer, arthritis, Alzheimer’s disease, heart disease. The ocean is also an ally in fighting Covid 19.
