In his satirical Devil’s Dictionary, Ambrose Bierce defined the ocean as ‘a body of water occupying about two thirds of a world made for man – who has no gills’. Bierce may have been right to poke fun at human arrogance, but he underestimated the importance of the seas. Averaging almost 3,700 metres (12,000ft) deep, the ocean constitutes around nine tenths of the habitable space on our planet. It plays a commensurate role in the Earth system, not least as an engine – a ‘blue machine’ in the phrase that also titles an excellent book by the physicist and science presenter Helen Czerski – that moves heat around the planet.

‘Let me leave Cairn here as a trail marker, a moment noted, a view from the strange here-and-now,’ Kathleen Jamie states towards the end of the prologue to her exquisite new collection of writings. In more than 40 micro-essays and poems, her keen-eyed view encompasses both an uninhabited island far out at sea and a piece of flint in her hand; it accommodates surfacing memories and also peers into the uncertain future awaiting the next generation. A balanced tower of ultra-short pieces is a new form for Jamie, the Scottish makar (or national poet), who also pens longer pieces of nature writing, collected into the genre-expanding works: Findings, Sightlines and

Masters wrote to Dennis Nilsen. Nilsen wrote back: ‘Dear Mr Masters, I pass the burden of my life on to your shoulders.’ After Nilsen had filled 50 prison notebooks, Masters embarked on Killing for Company, surely the grisliest yet most poignant

Caspar Henderson writes beguiling books about the natural world, full of eyecatching detail and plangent commentary. His Book of Barely Imagined Beings: A 21st-century Bestiary came out in 2012. A Book of Noises is a worthy companion – a pursuit of auditory wonders, a paean to the act of listening and a salute to silence. Item: the music of the spheres. (The planets’ orbits, proving unideal and elliptical, suggested to the musically minded astronomer Johannes Kepler an appropriately sad, minor-keyed leitmotif for the Earth, where, he felt, misery and famine held sway’.) Item: the world’s loudest sound. (The asteroid Chicxulub that killed the dinosaurs 66 million years ago; also an
