Dry Lab (Rebecca Oliver/JNCC)
The wet lab is, like the name suggests, where the wet, mucky work happens. Here, we store the sieved grab samples we bring on board and prepare them for later analysis. Before they come inside, they are sieved through a 5mm and 1mm sieve on deck. This separates out any macrofauna species (>1mm) living within the sediment which we then preserve for lab analysis once we are back. We also keep a separate sample of the sediment so we can measure the size and distribution of the component particles: this is known as a PSA sample (particle size analysis).

Stage 2: The Hamon grab sample once removed from the grab, prior to sieving (JNCC/CEFAS).
Stage 3: The sample is washed through two sieves; firstly a 5mm sieve (above), then a 1mm sieve (right). In this sample we found a sea potato, an Echinoderm that lives buried in the sand and is covered in hair-like spines (JNCC/CEFAS).
