Your best rockpooling photos | Big Seaweed Search

Seaweed scientist Professor Juliet Brodie tells us about the fantastic photos submitted through the Big Seaweed Search so far.

I’m fascinated by seaweeds and my research includes finding out about their diversity, and the impact of climate change and ocean acidification on their distribution. As part of this, I worked with my colleagues across the Museum to set up the Big Seaweed Search and I’m so pleased to see that lots of you have taken part and have sent your photos in for my research. I’ve just been exploring the first few months of data entered and I’m very excited by what I have seen so far.

Some people think seaweeds are dull and brown but I was very taken with this beautiful image of the pink coral weeds (white arrow) and calcified crusts (black arrow) growing together. Photo © Jessica Jennings

In particular, the photographs people have uploaded are excellent as they enable me to tell very quickly whether a seaweed has been identified correctly or not – this is essential for me to be able to use the observations in my research.

If you go down to the beach today | Big Seaweed Search

This week HLF Identification Trainer of the Future, Anthony Roach, introduces us to the marvellous diversity of seaweeds on Britain’s shores and shows you how you can contribute to citizen science by recording them as part of the Big Seaweed Search.

Seaweeds are incredibly diverse and beautiful organisms. They are strong biological indicators of the health of our environment and play an important role in the marine and coastal environment, despite being perceived by some as drab, slimy, green and brown sludge hanging from the rocks or smelly dried husks that litter the high tide mark. The Museum’s seaweed researchers and staff at the Angela Marmont Centre for UK Biodiversity are therefore encouraging everyone to learn more about seaweeds, to map their diversity and assess how they are responding to climate change through the Big Seaweed Search.

I grew up near the coast in Devon and I certainly over-looked seaweeds when whiling away countless hours rock pooling. I would slip and slide my way over seaweed covered rocks in search of the jazzier or more colourful marine stars of the rock pool such as crabs, starfish, sea anemones and blennies. I have discovered however that there is so much more to seaweeds than at first meets the eye.
