Read the platform name
NOAA Ocean Exploration defines an ROV as a remotely operated underwater vehicle connected to a surface vessel by a tether carrying signals. It describes an AUV as an untethered autonomous underwater vehicle. These definitions distinguish operating arrangements, not simply two names for any underwater camera.
Some platforms can support more than one operating mode, so use the expedition’s actual description. Do not classify a vehicle only by its shape or by the presence of a camera.
Keep the view and the control room separate
An expedition programme can cut among a vehicle camera, shipboard scientists, a map and recorded highlights. A shipboard conversation is not itself a camera view from the seafloor. Read labels identifying the vehicle, dive and date at each transition.
NOAA’s account of autonomous glider work describes data being transmitted when an antenna reaches the surface or being accessed after recovery. An autonomous survey therefore does not automatically imply a continuous real-time video feed to viewers.
Interpret the observations within their frame
Record the dive location, depth unit, time and camera source when provided. A close-up animal shot does not establish the size of the full survey area or the abundance of that species across an ocean. A map of the vehicle’s planned route is also different from a completed track.
Do not infer that every movement on screen comes from an animal. Vehicle motion, camera direction, lighting and particles in the water can affect the scene. Use the scientists’ identified observations rather than assigning a cause solely from appearance.
Choose the right item to share
If recommending a dive, link the expedition’s original page and identify whether the item is live coverage, a complete recording or selected highlights. Keep the vehicle name with the clip. This lets another viewer find the corresponding dive information instead of assuming a generic ocean thumbnail identifies the event.
This article promises no current expedition schedule or Canadian playback. Its practical purpose is to connect a striking underwater image with the platform, place and recording context that make it scientifically useful, while leaving unsupported claims about continuous control or immediate data delivery out of the description.

Are ROV and AUV interchangeable labels?
No. NOAA distinguishes tethered remote operation from autonomous untethered operation.
Does every autonomous dive provide live video?
No. Read the expedition’s data-return description.
