This Thursday was only sunny, but also not windy, with a good low tide in the early afternoon, which meant I reserved a few hours to go to Tunnel/Castle/Gylly beach for some snorkelling. The photo above shows Gylly Beach, with the start of Swanpool lagoon behind it and the Lizard in the far distance. (I took this with my iPhone using a Hipstamatic filter; for more iPhone pics of Cornwall see cornwall_hipsta on instagram…). The water temperature was OK (9C?) but the viz was not as good as I hoped. The seaweeds are at their peak now and the pools looked very pretty. Not many fish, but I saw a small brown thing floating around which I first thought was Sea hare, but turned out to be a small (perhaps a Connemara) clingfish lazing about until it noticed me and bolted into the seaweeds. I carefully snorkelled in about half a meter of water, admiring the views and trying to take photos close-up (as the viz was not too good) with my wide angle wetlens. Below an above-water shot of some iridescent Bushy rainbow wrack Cystoseira tamariscifolia and the invasive red Bonnemaisonia hamifera (on the left). I need to go back studying photography basics. A main challenge is contrast. The pools have beautiful white sand, which result in hugely overexposed photos (or completely darkened subjects). I have come up with my own law, the Photography Frustration Index (PFI): the beauty of the subject (B) x the difficulty of capturing it (D). The PFI is very high in the case of seaweeds! Next: Bushy rainbow wrack under Thong weed, Purple claw weed Cystoclonium purpureum, Bushy berry wrack Cystoseira nodulosum covered with the epiphytes Asparagopsis (left) and Bonnemaisonia (right), Hairy sand weed Cladostephus spongiosus, Black scour weed Ahnfeltia plicata (you can see they grow in the sand and must be used to scouring) a ‘bouquet’ of different species (with a snakelocks anemone) and a last photo of a variety of species, including the common False eyelash weed Calliblepharis jubata. The tides and weather conditions are unfavourable the coming days but I hope to go snorkeling again end of the week!
OK, it was the plan to post a general Falmouth seaweed/rock pool photo post every month but I am faltering the second month in… It is not for lack of trying, because I have been sneaking out of the office quite a bit, but the weather has been pretty awful. Lots of wind, choppy waves, rain, cold and bad viz. I had one good day this week and I am posting some of the better pics from that session. Again a photo of Nursehound mermaid’s purses attached to Bushy rainbow wrack, pretty much the only seaweed species these sharks use to attach their egg cases to. This must be because this seaweed species is very sturdy, and especially because it is a perennial: the eggs can take up to twelve months to hatch! Below three more Bushy rainbow wrack Cystoseira tamariscifolia photos. The first photo shows a short plant with few epiphytes but the following photo shows that this species is an especially great substrate for all kinds of other seaweeds, including Harpoon weed, Fern weeds and Juicy whorl weed. The plant in the third photo (unfortunately out of focus) is completely covered by a beautiful flat red species: Above a general impression of the scene before the sun reappeared. Btw, most of the photo’s have not been post-processed but some I have tweaked a little using the standard photo editor that comes with Windows 10, which is actually really good. The seaweeds have been growing quite a bit since January. A few have become more prominent, such as Slender wart weed Gracilaria gracilis (first two photos) and (I am not 100% sure) Purple claw weed Cystoclonium purpureum in the two photos after that. I have a bunch more photos that show different seaweed species, but I hope that I can take better pictures of these later this month for a follow-up post (I am trying to find a balance between showing what I have seen and posting ‘good’ photo’s, which is a bit tricky!). I have a macro lens now as well, which I will mainly use for animals but also can be used for the smaller seaweeds; the last photo is a first attempt.
