Welcome to the 2016 Learning Zone Minecraft Oceans Competition!

The goal is to build the best model of the Sentinel-3 or Jason-3 ocean-monitoring satellites, or get creative and design your own satellite and/or ocean monitoring system with buoys, automatic robots etc.

For the first category, we will provide you with 3D views of the Sentinel-3 and Jason-3 satellites, for you to recreate in Minecraft. Build one, two or both, the choice is yours!

Jason-3: monitors the ocean surface height collecting data for weather forecasts and climate monitoring

Sentinel-3: monitors temperature, sea-level, and ocean colour (e.g. phytoplankton which are tiny marine plants)

For the second category, the sky is literally the limit! Go crazy thinking up an interesting design for your ocean monitoring satellite.

Show us what it can do and why and you can even design your own ocean monitoring system using the image of the Global Ocean Observing System as your inspiration.

Who can enter?

The competition is open to entrants aged between 6-16 years in three age categories (6-8, 9-11, and 12-16).

How will submissions be judged?

In all categories, submissions will be judged on the following criteria:

Concept & Originality
How well you have interpreted our satellite’s design or how original your own design is

Technique & Execution
From your attention to detail to the overall impact of your creation on the judges

Time spent presenting your submission, how good your screen shots and description are.


We’ve got some great prizes on offer, so don’t be shy to join in - you stand as good a chance of winning as anyone else.  There is a first and second prize for all three age categories of entries, so get building!

startermapHow do I enter?

Please read the following rules and instructions carefully.

1 - Create the starter map using our 'Seed'

Tested in Minecraft 1.7, 1.8, 1.9 (PC/Mac)
There is no Ocean Monument in 1.7.

2 – Build your creation

Projects entered into this contest must have been your idea and created for this contest by you.

Be creative, but please keep within the boundaries of the starter map.  Feel free to build on the island, in the water around it or above it.


  • Creative Mode - use whatever Minecraft materials you like!
  • Teamwork - you can recruit help from others but you must be the mastermind and team leader. They must understand that only you can enter the final project. If there is significant drama about who created the project, we will have to disqualify it
  • Map Editing Tools such as MCEdit, WorldEdit, VoxelSniper, etc.
  • Third party texture packs - feel free to use them but you should keep in mind that others, including the judges, will likely not have your texture pack installed, so your safest bet is to stick with the default pack. Using an extreme or customised texture pack may hurt your chances of winning.

  • Do not use 3D or 2D auto conversion / import scripts
  • Do not use third party ‘mods’ that introduce new blocks that are unavailable in the standard Minecraft game.

If we suspect you have done any of the above in your entry, it will result in your disqualification. We can disqualify at any time, including after the submission period, so please do not cheat.

 3 - Submit your creation to the competition page

Take some high quality screenshots of your creation and submit your favourite through our competition entry page. You should also provide a caption to tell us about what you built and provide any links to additional photos or videos you have created and uploaded elsewhere.

Once you have uploaded your entry, you can view the other competition entries, leave comments, vote for your favourites and even share your entry on Facebook or Twitter!

Most importantly, don't forget to upload your entry photo before the entry period ends!


If you have any questions about the competition, send us an email.
