Here is a list of frequently asked questions:

How does my contribution help researchers to conserve Swedish's marine ecosystems?

By recognizing the habitats, species, and presence of litter on the seafloor, you will allow us to filter out crucial information from over 20 years of recordings and study how the fauna on the sea floor has changed in response to warmer waters, intense trawling, and the inauguration of a National park.

I just can't decide. Why isn't there an "I don't know" option?

We need you to make your best guess. Humans are really good at pattern recognition, so your first guess is likely the best answer. Other people will review the same video, so it's okay if you make mistakes. Having several people review the same video and offer their best guesses for the classification is how researchers figure out what species are recorded in the video and if the video meets quality requirements.

What should I do if I see a unique animal and there is no option to classify it?

If you see animals that are not included in the identification options, select the "Nothing here" choice and use the talk bottom to leave a comment about what you saw. This helps flag the videos for the researchers so that they can include the option in the list of choices.

How can I sort my favourite images or films under a given topic?

You can organise clips in an existing collection or start a new collection. Once you created a collection or added the clip to an existing one, you can click the tab "Collect" in the main menu and start a conversation around a what you saw.

In the above picture, if you press the link in the red circle, you add this clip to an existing collection (e.g. "unusual observations"), or you can start a new collection.

*In the above picture, if you press the tab "Collect" in the red circle, you can see collections of clips organised by other users. You can comment on the videos, add notes or start discussions.

Why is the quality of movies relatively low

Underwater images are usually of poor quality when compared with images and movies taken on land land. This is beacause there is little natural light below 20 m, while the water is often turbid and filled with particles blurring the recordings. In addition, the camera may not stand still while filming because of the currents in the water. Together these factors often create fuzzy images and these conditions are almost impossible to control for. Hence we have to work with the image quality as is.

What are the two red dots that I see in the movies?

The camera sends two laser beams to the seafloor in order to be able to have a reference measure for size and distance. The two red dots are always 50 mm apart.

What is the cable that I see in some videos?

Sometimes there is some hardware visible in the films/images. These can be parts of the ROV (e.g. grapples, headlamps) or experimental installations on the seafloor (e.g. cages or artificial reef structures).

Can I contribute with my own videos or images?

If you want to contribute with own images/films, contact the team using the questions to the researchers board of the "Talk" section.

What if I see two ore more species?

Corals, sponges, and crustaceans often appear in the same clip. The questionnaire allows for multiple choices, so make sure you label all the species that you see before hitting the submit bottom.

Many individuals of the same species appears at different times, how do I record them?

We would like you to record the first time any individual of the species fully appears in the screen. Using this information, along with machine learning algorithms, we will work out when different individuals of the same species appear on the movies.

The species never fully appears in the video, how do I record this?

If the entire animal is never fully recorded in the video, please select the second that captures most of the animal's body.

How do I start a conversation/discussion?

There are 2 ways to have a discussion. First, you can start discussions associated to images/films (explained under FAQ 3 above). Second, you can start a discussion in our "Talk" section.

In the above picture, if you press the tab "Talk" in the upper right menu (red circle), you can add questions/answers to any of the existing conversation topics. You can also suggest a new discussion threat under the topic "Questions to the team".

How can I ask a question that is not in the FAQ?

You can ask the researchers your questions in the questions to the researchers board of the "Talk" section.

In the above picture, if you press the tab "Talk" in the upper right menu (red circle), you can add questions/answers to any of the existing conversation topics. You can also suggest a new discussion threat under the topic "Questions to the team".
