Plankton Portal

Plankton Portal turns images from a sensor-packed underwater camera into a citizen-science sorting job. The project connects tiny, often strange-looking ocean life to serious questions about food webs and changing water conditions, though the current workflow appears to be between reliable batches.

What is Plankton Portal?

The pictures come from ISIIS, a camera system towed through the sea like a virtual net. Instead of hauling a jar of mashed-together specimens aboard, it records plankton in place alongside environmental measurements. Volunteers have historically helped sort those images so researchers can turn an enormous visual stream into usable categories. The present Zooniverse pages point to a California Current workflow, but their active numbers do not line up: the landing page reads 81 percent complete, the workflow reads 99 percent, and both show zero active subjects. For now, the research and team pages may be more dependable than the classify button.

What you can do there

• Classify plankton in underwater images when subjects are available
• Read about the imaging system and research team
• Discuss unusual subjects in Zooniverse Talk

Why we picked it

Plankton Portal gives the phrase ocean data a wonderfully literal face: translucent larvae, drifting jellies, and other specks that are easy to miss but hard to forget. Its strongest trick is making a vast imaging problem understandable as one careful visual decision at a time, while keeping that decision inside a larger scientific process.

How to get the most from it

Read the Research page first so the grainy shapes have some context, then try the California Current classifier. If subjects appear, lean on the field guide and choose conservatively; use Talk for a puzzling organism instead of forcing certainty. A short, attentive session is more useful than a speed run.

Good to know

Current availability is uncertain: the project advertises a starting point, yet its active counters are zero and its completion percentages disagree. The original project dates to 2013, while the displayed 2019 date belongs to the migrated Zooniverse version. Personal statistics require sign-in; live submission, device support, accessibility, and image-reuse rights were not tested.
