"This app is a total game-changer for my coastal field trips. Being able to identify species offline at remote beaches without carrying heavy field guides is incredible. The illustrated questions make it so easy for my students to engage with marine biology without getting bogged down in academic jargon."

"As an avid tide-pooler, I have used many guides, but none are as user-friendly as Seaweed Sorter. The photos are stunningly clear and the 'could be confused with' section is brilliant for pinpointing exact species. It is like having a UBC professor right there on the beach with me."

About the app

Everything you need to know about Seaweed Sorter.

Description

Seaweed Sorter helps users identify 130 species of macroalgae commonly found along the west coast of British Columbia, Canada, including many species that extend from Alaska down to Washington, Oregon, and northern California. Unlike printed dichotomous keys, which use jargon and often require specialized knowledge, Seaweed Sorter uses easy-to-understand, illustrated questions that assume no prior knowledge and allows users to skip questions at any time. Seaweed Sorter includes more than 300 photos, current and former names, taxonomic details, clear morphological and ecological descriptions, and lists of other seaweeds that “could be confused with” your specimen – all curated by Dr. Patrick Martone (Professor of Phycology, UBC). Books can be quickly out-of-date, but Seaweed Sorter content will be updated frequently with taxonomic revisions, additional photos, new species, and more. Plus, content is available anytime and doesn’t require an internet connection, making Seaweed Sorter an excellent companion on any trip to the coast. Great for educators, students, consultants, and naturalists!
