The POWER of citizen science and collaboration

Citizen scientists are changing the way we understand our oceans 🌊🔬

Thanks to thousands of observations submitted through Redmap, Reef Life Survey, and iNaturalist, researchers discovered that 91% of marine species range extensions around the Australian continent were previously undocumented in scientific literature. This highlights the critical role of citizen science in detecting early signs of climate-driven changes across Australia's vast coastlines.

Poleward range shifts of tropical species in response to ocean warming

Redmap sightings have contributed to a new paper in the Journal of Global Change Biology exploring the physiological mechanisms underpinning tropicalization — the poleward range shifts of tropical species in response to ocean warming🌡️

The Spring 2023 Redmap Newsletter!

In our Spring 2023 newsletter, we'll introduce you to some new faces in the Redmap team, give you a comprehensive guide for distinguishing Southern Rock Lobsters (Jasus edwardsii) and Eastern Rock Lobsters (Sagmariasus verreauxi), share insights on fisheries and climate, highlight some fascinating citizen science projects, plus an interview with David Maynard, one of Redmap's pioneering observers and throw in some other interesting stuff too!

Fish are moving south to keep up with climate change - and this scientist is keeping track of them

Dr Barrett Wolfe discusses his latest paper, titled Continental-Scale Assessment of Climate-Driven MarineSpecies Range Extensions Using a Decade of Citizen Science Data, which uses citizen science data, including Redmap data with 3CR Radio 

Interview with David Maynard, one of Redmaps first ever observers!

David first joined Redmap in 2011. The out-of-range species sightings he has logged since then have made our database broader and more comprehensive, helping us determine what’s happening in Australian waters!

Here is a short interview we did with Dave to dive deeper into his life as an ocean enthusiast and the path he his taken as a marine scientist, including his role as a FRDC extension officer and his connections …

What's in your pot? Know the difference!

Eastern Rock Lobster (Sagmariasus verreauxi) are on the move! Do you know how to tell them apart from the common Southern Rock Lobster (Jasus edwardsii)? Help Redmap Australia track the southern expansion of this species by logging it if you spot one in Tasmania or South Australia!
