Welcome to the changing Arctic Ocean. Polar researchers from the UK and Russia have contributed to this Special Issue of The Marine Biologist to bring wide-ranging content and fantastic images that will really give you a flavour of this cold and remote ocean and its global importance.

Highlights include an article on the MOSAiC project - the biggest Arctic expedition in history, and a conversation with the Director of the British Antarctic Survey (BAS) Professor Dame Jane Francis about the UK's new polar research vessel—the RRS Sir David Attenborough—and the future of ship-borne polar research. Thanks to support from the Natural Environment Research Council (NERC) we have been able to include an A3 pull-out poster showing all the special features of the Sir David Attenborough.

Welcome to the editor's blog!

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.
