Expert-Student-Computer-Citizen Scientist: How does the crowd compare?
What do you do when your experiment returns a variety of results? You run a second trial. Hey that’s real science. So, here is the challenge: We need more comparable results from our sablefish competition. We need to compare apples to apples or in this case sablefish to sablefish. So, this time we are asking you to count the sablefish exactly as we are doing in our labs.
We have added the full video clips from Barkley Canyon, where we sampled 1 minute every half hour to study the behaviour / activity rhythms of the animals.
We now have a newly developed computer automated program and are further testing its reliability and we need your help. Can you be the scientist?
Here’s the big challenge. For this mission, we’d like you to count or in some cases recount the sablefish (black cod) for the entire segment of the clip – up to 1 minute of your time!
Seems simple enough…
Ever wondered whether you are doing the work of a citizen scientist or just part of the crowd? Why does it matter?
Digital Fishers developer and colleague, Justin Longo is now doing his post-doctoral work out of The Center for Policy Informatics at Arizona State University. With the winning of a new grant from the Office of the Vice President for Entrepreneurship & Innovation under their Citizen Science & Citizen Engagement (CSCE) Grant Program he relooks at Citizen Science and asks this question of the distinction between the two.
Justin, has always had me using the term “science-oriented crowdsourcing”. I liked reading the post and revisitng just why.
He makes the case:
“…that there is an important connection between the terms “crowdsourcing” and “citizen science” – or, to be more precise, between what I call “science-oriented crowdsourcing” and “Web2.0-enabled citizen science”. My interest here is in trying to more precisely define the type of citizen science we’re talking about, and where it intersects with crowdsourcing.
First off, what strikes me as unhelpful is that there’s a noticeable preference in the citizen science movement against the term crowdsourcing, as though crowdsourcing were something less serious than citizen science. For example, the Citizen Science Alliance - the organization behind the Zooniverse - very precisely and carefully does not use the term crowdsourcing in its writings. Crowdsourcing is for making t-shirts, citizen science is for identifying galaxies. Maybe it’s just me, but I think there should be a more objective difference between the two terms.”

Justin‘s new project is the “Citizen Science to Forecast the Future of a Desert City” and the other is the “Crowdsourcing the Next Great Citizen Science Project” project. He is currently a visiting research fellow at the Centre for Global Studies, at the University of Victoria and will return to sunny Phoenix in the fall.
Crab Detective: Challenge the computer & search for crab!
Our researchers need your help to evaluate their methods for the automated detection of that mysterious sea-floor animal – the crab. Although video provides a rich source of information crabs create a unique challenge. Normally, large amounts of data are put through techniques using motion sensors as the most common cue for automatic detection. However, some animals such as sea stars, sea urchins, gastropods, some fish and especially crabs exhibit very little motion and are not easily detected.
A tool that does not rely on motion for detecting the presence of animals is being developed. While, this tool uses shape and colour information, crabs and other sea-floor animals, are challenging to detect because of the uneven lighting deep in the ocean, the presence of objects that are of similar color and the significant variation in geometry because creatures like crabs often have part of their body hidden in the sand.
We need to test if this new tool is reliable and we need help. Your mission will be to annotate videos of the seabed that include stationary or quasi-stationary crab(s). Your annotations will be used in a study to compare against the software program…what we call “ground truthing”.
*IMPORTANT: Sometimes you will see crabs in more than one corner. Please only annotate for one corner at a time. To tell us about crabs in other sections of your screen (top right, top left etc.), please let the video play for another second, pause and repeat the step above.
*If you are a returning user, this is a different task than you are used to.*
Just before the weekend, we became aware of a malware infection that infected the DigitalFishers.net site.
We have determined that the problem originated with a WordPress plugin (though we still do not know which plug-in it was). We have disabled all possible plugins, and the problem is now fixed.
We have applied to Google to have our current blacklist status erased.
Hello Digital Fishers,
You have done such a great job mapping Mapping Seafloor Geology at Endeavour Ridge. There were 15, 791 annotations which resulting in thousands of data points. Thank you! We hope to have a bit of a map of what you saw posted as soon as we input all the data.
In the meantime, we have another similar mapping challenge we need your help with:
Investigation of NEPTUNE Canada’s future abyssal observatory!
Help our scientists decide where to place our instruments and cameras. In order to plan experiments for this site, we need your help developing a better understanding of the organisms found in the area and the general characteristics of the seabed. Your mission will be to annotate video segments from the area with information about seafloor organisms and seabed properties.
Over the next 3 years the NEPTUNE Canada network will be expanding instrumentation at its abyssal plain site in the northeast Pacific to permit time series observations of deep-sea ecological processes. This data will provide us information about species abundance, community composition and habitat features. Your data will be assembled into a map by our metadata team that you will be able to view following the end of the campaign.
You never know what you will see almost 3000 metres under the sea!
We couldn’t let the week go by without commenting on the video that is going viral on oceannetworks canada‘s YouTube channel.
It is incredible to see the connection that the NEPTUNE Canada array can have across the world. We keep talking about the power of the crowds and the opportunities that every day citizens like you our Digital Fishers can have and here is a real life example. How do you connect people with the scientists? This young man Kirill shows that you don’t need a PhD to spot something out of the ordinary; but, you do need a someone who is willing to work with you to connect the dots and that is just what NEPTUNE, VENUS, and Oceans Network Canada did.
If you haven’t had a chance to read all about 14-yr old Kirill Dudko from the Ukraine, his love of the ocean, and his discovery of an elephant seal 894 metres under the sea slurping up a hagfish meal, click on the links below.
BELOW IS A SNIPIT FROM THE POST ON NEPTUNE CANADA NEWS
“Kirill grabbed the clip and posted it on his YouTube channel, then sent us a message asking if we could help identify the creature that caught the hagfish. We put the word out to marine mammal experts in Canada and the US, who identified the mystery animal as a female northern elephant seal. This is our first sighting of an elephant seal in seafloor footage, recorded by a camera situated 894 m below the surface.”
How are geological features distributed at a mid-ocean ridge?
Please help us with our next challenge. For this mission, we have added videos from Endeavour Ridge where the seafloor exhibits spectacular geological features. We need your help in this seafloor mapping expedition of a mid-ocean ridge.
Details of the seafloor geology through video will enhance current bathymetric data sets (underwater maps) and enable better planning of the NEPTUNE Canada network. Also, scientists will be able to use this data to better understand the dynamic geological history of the ridge. Correlating geological features with select animals will also help scientists better understand what affects species distribution in one of the most extreme habitats on earth.
For this mission, we’d like you to describe structures in the seafloor and pay close attention to a few selected species.
Some of you have asked for a more detailed explanation of the scientific research being done by the “competitors” of this new campaign and why it is important to learn more about the data that you, the Digital Fishers, are producing.
We asked Marjolaine Matabos and Maia Hoeberechts, Research Theme Integrators at NEPTUNE Canada, to help us understand the science.
What are activity or biological rhythms and what is important about this type of research?
Activity or biological rhythms are any rhythms in the life of an organism that follow a natural cycle like the daily or tidal periodicities. For example, some species bury themselves at certain moments of the day, others will migrate along the slope from deep water to shallower water following the tide. The study of those rhythms is called ‘chronobiology’.
