A very warm welcome, wherever you are, to our first ever January edition!

In this edition we ask, how will we relate to nature and go about science in a fast-changing world? 

A very warm welcome to the first July edition of The Marine Biologist magazine! Since its creation in 2013 the magazine has been very well received and we have been privileged to publish many wonderful and fascinating articles.

We are proud to have published over 190 original, informative, and inspiring articles spanning all aspects of marine biology, written by contributors ranging from world-famous ‘ocean elders’ to volunteers, and scientists at the start of their careers.

Welcome to the latest edition of The Marine Biologist magazine, in which we celebrate the

A warm welcome to issue 13 of The Marine Biologist magazine. As you will have guessed from the cover, this edition has a polar flavour. Climate warming is bringing change faster in the Arctic Ocean than anywhere else on the planet.

From drones to the DNA in a shrimp's gut, our capacity to observe the ocean seems to be limited only by our imagination. All this accumulating data is potential evidence in support of sustainable management of the marine environment.

A warm welcome to The Marine Biologist magazine. A full range of material awaits, including brain-eating parasites, entangled cetaceans, trophic cascades, and more.

The future ocean can look like a scary place: hotter, more acidic and breathless. In the wake of stories about longer and more frequent marine heatwaves our cover story (page 10) looks into the effects of a warmer future in Antarctica.

Whether this finds you in an austral spring, a boreal autumn, or a tropical monsoon, we wish you a warm welcome to The Marine Biologist magazine.
