Citizen scientists contribute to new global database of marine forests

“All around the world we’re seeing changes in our underwater forests due to climate change and other human-caused disturbances. Some marine forests are sadly disappearing, while others are starting to appear in places where they traditionally haven’t occurred”, says Dr Cayne Layton, a marine ecologist at IMAS and a volunteer regional coordinator for the Marine Forests citizen science project. “And so this project is partnering with citizen scientists from around …

Bioluminescence: the ocean’s shining light

Bioluminescence is undoubtedly a wonder of the natural world that’s capable of captivating the imaginations of those who witness the phenomenon, including the father of evolution Charles Darwin whose first notebook entry while aboard the famous Beagle voyage remarked that:

“The sea was luminous in specks and in the wake of the vessel, of a uniform slightly milky colour. When the water was put into a bottle, it gave out …

Redmap launches into Queensland waters!

Redmap’s Queensland chapter has been operational since our national launch in 2012, but today we announced our intent to enhance our engagement with Queensland’s marine users to better understand the changes that are occurring in one of the world’s most iconic marine environments. Read on to learn more about what was announced at the formal launch held at James Cook University in Townsville today, and to also see our revised …

Increasing opportunity for kingfish in Tasmanian waters

Sightings of yellowtail kingfish in Tasmanian waters have been regularly logged with Redmap since the program began. These records are particularly valuable because they indicate that kingfish from eastern Australia could be on the move south, suggesting that some dedicated scientific research may be necessary to get to the bottom of what’s going on.

In this article, PhD student and kingfish project leader Curtis Champion describes recently published findings that …

Diving into the genetics of range shifts

Jorge E. Ramos is a marine biologist with a PhD in Natural and Physical Sciences from the University of Tasmania. His PhD project focused on examining the life-history characteristics, genetics and population dynamics of the range extending common Sydney octopus (Octopus tetricus).

Searching for patterns in the genetics of range-shifting animals can help us to understand why some animals, and not others, are shifting where they live …

Marine heatwaves: a formal classification system

Just as floods, cyclones and droughts are considered extreme weather events on land, extreme climatic events also occur in the ocean. Work being undertaken by the Marine Heatwaves International Working Group has resulted in the development of a formal definition and classification system for these extreme marine events, allowing for global patterns in their occurrence and duration to be assessed.
