During April the BBC Sardine Run team meet up in Plettenberg Bay to focus on capturing more footage for the Earth’s Great Event Series. Unlike last year, where I had been assisting Jusin Maguire topside, Hugh Person shifted me onto the underwater team to assist Didider Noirot, and to film underwater footage and stills for the making of section. We were plagued by bad visibility for much of this shoot - this image of a common dolphin and her baby shows just how bad - a function of upwellings and plankton blooms. In late May we kick off another five week shoot, our last chance to capture this compelling, dynamic yet elusive marine phenomenon.
