Each day of the field trip, the LEARNZ Team shoot, edit and upload curriculum-rich videos which help students to feel right up close to the action.
For help and more information about LEARNZ videos, go to Help with Videos in the LEARNZ Support section.
You have been through the security gate and have arrived at the busy Center Port, Aotea Quay in Wellington ready for the departure of the RV Tangaroa.
Next step learning: Find out more about the two research organisations that are supporting this field trip: NIWA and NOAA.
The bridge is high up on the Tangaroa with a spectacular view of the decks and the surrounding sea. This is where the ship is controlled.
Next step learning: Find out about nautical miles and knots and why sailors use these measuring units.
Your ship takes a bit of getting used to! It has many corridors, stairways and decks. Visit the galley, the TV room, your cabin and the bridge.
Next step learning: Most ships have a monkey island. Yes, a monkey island! Find out what this means and see if you can find another interesting word or phrase used in the shipping industry.
1. Regular and Deep Argo Floats - Play or download 46Mb mp4 file or Watch on Vimeo.
You are in a small storage room off the main working deck on the RV Tangaroa. Your expert today is Nathalie Zilberman from the Scripps Institute of Oceanography.
Next step learning: Write down three questions about ocean currents. Now try and find some answers to them.
2. The CTD - Play or download 79Mb mp4 file or Watch on Vimeo.
Today there was a test of an important piece of equipment called a CTD. It took most of the day to prepare and was finally lifted off the deck and lowered by cable 2,000m into the ocean. You are with oceanographer Esmee van Wijk in a lab just off the Tangaroa’s main deck.
Next step learning: Find out where the very deep oceans are. Where are the deepest parts near New Zealand?
1. Researching the Undersea World - Play or download 52Mb mp4 file or Watch on Vimeo.
The library is a nice quiet space on the RV Tangaroa with a coloured map of New Zealand. But this is no ordinary map. Oceanographer Phil Sutton uses the map to show where you are and to explain why we are here (and not somewhere else!).
Next step learning: Find out about how greenhouse gases warm the planet.
2. Preparing a Regular Argo Float for Deployment - Play or download 29Mb mp4 file or Watch on Vimeo.
There is a special brown box on the deck of the Tangaroa. It is tied up with yellow tape and is being prepared for a big adventure! Inside, the Regular Argo Float is all set for a lifetime’s work out in the oceans.
Next step learning: Think about all the costs of deploying an Argo Float. Write down as many as you can.
3. Deploying a Deep Argo Float - Play or download 39Mb mp4 file or Watch on Vimeo.
The Deep Argo Floats are very new. The prototypes on this voyage are called ‘Deep Solo II’ Argoes. They are being released to see if they can successfully travel down to 5,500m and still return to the surface to send their information to satellites. Scientist Nathalie Zilberman tells the story.
Next step learning: Find out about the word prototype. Describe a prototype (eg a vehicle or machine).
The Deep Argo is a clever robot designed to do a very special job. On this voyage you are part of the process of evaluating a prototype Deep Argo. This is part of a technology process to produce a fully tested and working Deep Argo robot.
Next step learning: Find out about other planning tools, systems and processes (such as Gaant charts) that help with technological practice.
On this voyage you will see two prototype Deep Argoes being deployed. The first deployment went very well. How will this one go? Oceanographer Nathalie Zilberman talks you through the deployment, and explains the purpose of having two Deep Argoes at this one location.
Next step learning: Once the first test dives are completed these prototype Deep Argoes will move down to the ocean floor sending data to a satellite and on to Scripps Institute of Technology in California, when they surface. Make a list of all the smart technologies you can think of that allow deep argoes to do this.
There are nine scientists on this voyage including Denise Fernandez. Denise is a PhD student, starting out on her career as a scientist.
Next step learning: Find out about other science careers that involve water (other than oceanography).
The CTD is a very important piece of equipment, and science technician Matt Walkington is the man to talk to about it.
Next step learning: Find out about electronic sensors that measure things about the environment. What are they used for?
You’ve been on this voyage for seven days and during that time the CTD and two prototype Deep Argoes have made many trips down to 2,000m below sea level and some down to over 5,000m! The CTD is made of steel and hard plastic and comes back to the ship looking just the same. Would all materials survive unchanged by a dive to 2,000m? Here is an experiment to see.
Next step learning: Find out about vehicles that can travel to great depths in the oceans and the pressures they can withstand.
The main purpose of this voyage was to test prototype Deep Argo floats. But regular Argo Floats were also deployed on the way to, and back from the test site. Phil Sutton describes the two different ways that regular Argo Floats are put into the sea.
Next step learning: Record the number of the first Argo Float deployed on this video. Search on google earth for Argo Floats in this area (about 177°W 36°S) and look out for this Argo Float number to appear (it may take many weeks).
Take time at the end of the field trip to reflect on what you have learnt.
One more thing: To keep informed, how about putting a recurring item on your online calendar to check the Argo Floats using the Google Earth Argo App?
Oceanographer Phil Sutton, the Deep Argo Development Cruise Coordinator, summarises the aims and outcomes of this voyage.
