CAM-569
A dark slick moving towards the town beach
The mouth of a coastal town seen from above. On the turquoise water there is a dark slick covering half the bay, its edge already touching the stony shore next to the beach. A work boat with a crane sits at the harbour entrance and, closer to the edge of the slick, a service vessel. Behind them, the block breakwater with its beacon and the seafront promenade with people walking. On the right there is clean water, which is what makes the edge visible. IRIS does not say where the slick comes from or what it is: it says there is a dark surface on the water, that it has grown in the last few minutes, and which way it is moving.

What IRIS understands
What it recognises in this scene
- dark slick on the water
- edge of the slick reaching the shore
- work boat with a crane
- service vessel
- block breakwater
- beacon at the end of the breakwater
- stony shore next to the beach
- seafront promenade with people
- clean water outside the slick
- seafront of the town
The rule
You decide once. IRIS applies it always.
If
a dark surface appears on the water and keeps growing
Then
- raise a red alert with the shape of the slick and the direction it is moving
- save the video of the half hour before it appeared
- update the edge every minute for as long as the slick keeps growing
The instruction that set it up«Give me a red alert if a dark surface appears on the water and grows.»
What changes
What changes for whoever goes out, whoever decides and whoever justifies it later
In water, everything depends on the first hour. A slick spotted when it is already on the sand takes weeks to clean and ends up in the press; spotted while it is still a spreading surface, it is boomed off as it happens. The alert comes with the shape of the slick and the direction it is moving, which is exactly what you need to decide where the booms go, and with the video of the previous minutes, which is what later lets you reconstruct what was in the bay before. What the slick is, an analysis says, not a camera.
What people usually ask
Does IRIS say what the slick is or where it comes from?
No, neither of them, and saying otherwise would be inventing. A camera sees a surface changing colour, shape and position. Whether that is a hydrocarbon, an organic discharge or a mat of seagrass torn loose by a storm is what an analysis says, and no video can say it. Nor where it came from: the video can show which boats were in the bay before it appeared, which is a starting point for an investigation, not a conclusion. The conclusion is drawn by a person.
And a cloud shadow on the water?
It looks very similar for a second and then separates on its own. A shadow moves at the speed of the cloud, keeps its size and has no clean edge; a slick grows from a point, changes shape and leaves an edge. The rule looks at how it evolves, not at a single frame. And even so, the alert comes with the video, because dismissing it by looking costs twenty seconds and failing to dismiss a real slick costs a closed beach.
Is the recording usable as evidence?
That is decided by whoever has to assess it, under the applicable rules, and it is not for us to say. What we can say is what there is: a video clip with its timestamp, saved at the moment the event happened and not reconstructed afterwards. And one thing worth saying out loud in this sector: that same sequence serves as well to support a complaint as to take it apart. We do not keep it to prove anybody right.

Next step
Why did the line stop?
237 cases, and in every one of them IRIS raises an alert when something happens. You see each image as it is, and then with what it understands on top.
How many bays are free right now?
15 cases: 9 raise an alert when something happens and 6 only measure. You see each image as it is, and then with what IRIS understands on top.
And the best part
Video tells you what happened.An alert reaches you while it is happening.
Reviewing the recording helps you explain. Hearing about it at the time helps you get there. Two different things, and until now you only had the first.
Tell us your problem and we will say whether IRIS understands it, or not yet.
We reply the same working day.
