Welcome to Ultramarine 2023, our free e-book and audiobook that takes a deep dive into the science seeking to understand and protect our precious marine world. As anyone who’s rolled out of a boat in diving or snorkelling gear into deep water knows, there’s nothing as thrilling as entering the ocean and peering inside it.
Whether in warm tropical waters or the shiver-inducing brine of temperate and lower marine environments, Earth’s oceans and seas brim with life, wonder and mystery. As 2023 ticks to a close, our yearbook showcases some of the stories that have appeared this year under the Ultramarine banner.
We have published some 120 stories with a marine focus over the past nine months; a small selection of those appears in this free yearbook.
