Robot vs coral conservation

crown-of-thorns

Researchers at the Queensland University of Technology are closing in on trialing a new starfish-killing robot, the COTSbot. Crown-of-thorns starfish (COTS) have contributed to nearly half of the coral lost over the past 30 years on the Great Barrier Reef.

The COTSbot has been programmed to identify these harmful starfish from a wealth of other reef life, and deliver a deadly injection. Follow-up work will be done by teams of divers.

Outbreaks of this specialist corallivore have been blamed on changing land use on areas near the reef. Increased use of fertiliser washed into the sea has increased the amount of algae, the food source for crown-of-thorns larvae.

This great innovation will be a useful tool in taming crown-of-thorns outbreaks and ensuring that less coral coverage is lost. However, it is a technological solution to a systemic problem. The COTSbot only addresses the symptom of a lack of proper management of coastal areas near the reef.

This example could be used for a classroom debate looking at whether society is more keen on technological innovations to deal with environmental issues rather than looking at behavioural change that would address the problem at source.

This is number six in our follow-up posts to to XL Catlin Oceans Teacher Academy, sharing oceans education subject knowledge with teachers.

Ocean acidification is one of the processes threatening marine life and is included in the Coral Oceans and Frozen Oceans resources. This video shows two simple experiments for your classroom to show the process of ocean acidification and its impact on marine life…

The Incredible Edible Polyp activity is designed to be used in oceans education, and specifically with the Coral Oceans primary scheme of work, but has proved incredibly popular with all age groups and teachers alike. Here’s a video on how to make your own edible polyps with your class and a little twist on the classic anatomy lesson…

Here are two videos to introduce your classes to the work of the Catlin Ocean Expeditions. The first is a highlight video including clips and photos from the Catlin Arctic Survey in 2011:

The second is a Day in the Life video filmed with the Catlin Seaview Survey Shallow Reef team in the Bahamas in 2013 to give you a taste for a day in the life of a marine biologist:

As a follow-up to the XL Catlin Oceans Teacher Academy, here is one of the videos that is a great introduction to teaching oceans in the classroom and to brush up on a bit of subject knowledge.

This video from the great team at One World One Ocean is a brilliant introduction to the ecosystem goods and services that the ocean provides and a summary of the potential and current human impact on our marine environment…

When ocean currents go bad and paleoclimatologists become Hollywood heros, the trailer for The Day After Tomorrow and indeed the opening 10 minutes of the film if you can get your hands on a copy of the film, make an exciting and extremely exaggerated introduction to the world of thermohaline circulation and the impact of the Arctic ice on the gulf stream…

Dr Helen Findlay helped with this great animation on ocean acidification by pupils at the Ridgeway School in Plymouth. We hope you meet a great range of plasticine characters who can help explain ocean acidification and its impacts to your classroom.
