A bit of practice with over under shots two weeks ago when camping near St. Michaels Mount in Marazion. An ancient and beautiful backdrop to a fine sandy beach, with a causeway, rocky outcrops as well as seagrass. I was not alone and did not have much time and importantly no strobe handy, which made the exposure difference between under- and above water tricky. The main problem was however that I could not get up close to the Mount, leaving it quite small in the composition. Still, a great hour in the water. Many two-spot gobies were around and this is a site with lots of egg cases of the Nursehound (or large-spotted dogfish, or greater spotted dogfish or bull huss) Scyliorhinus stellaris.
Blogging slowed down a bit recently due to (variously or simultaniously) bad weather, work, bugs or unavailability of dive buddies. I entered one of the better photos I made this year (from this post) in the BBC Wildlife Magazine competition for fun and managed to get it published in the May issue, which was nice. I think I only went out once, which was a pontoon excursion in Mylor marina, the first time with the Canon G16. I tried some shots from above lying on the pontoon; I need to actually get in the water to get a better view of all the sponges, tunicates, peacock worms, mussels, oysters, anemones and seaweeds encrusting it. This shot of the Light bulb sea squirt Clavelina lepadiformis turned out best, but I believe there is a lot of room for improvement. I have bought a light which I will bring next time. I also ordered a strobe, so hopefully some proper dive photos very soon!
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.
Sunday was a beautiful spring day and we headed out to a new spot: Sandy Acres Beach on St. Ives Bay, North Cornwall. Beautiful dunes and a vast beach with very few people on it! With the kids running amok, I had only very little time to scour the high tide strand line. However, even with only 50 meters or so covered, it was the best bit of beach combing so far. Many cuttlefish bones, bits of Horn wracka and quite large mussels covered in seaweed holdfasts. Below a quick snap. At the bottom, I am not 100% sure, two Thornback ray Raja clavata- a Spotted ray Raja montagui and just above that a tiny Small-spotted catshark Scyliorhinus canicula mermaid’s purses (egg cases, see here for a useful key). Next to the mussel Mytilus edulis, some Hornwrack Flustra foliacea (a Bryozoan), two sponges which might be Mermaids glove and Chocolate finger sponge (thanks Steve Trewhella at the Beachcombing facebook group) and a spiky piece of Sea beard Nemertesia antennina, a hydroid. At the right of that a piece of a whelk Buccinum undatum egg cluster (better pic here). Not a bad haul, looking forward for a proper walk along this beach very soon!
This friday, I tried my hand at some more underwater rock pool photography with my point-and-shoot Canon Powershot (see also here and here). This is both rewarding as the colours of seaweeds are so vivid and the textures so varied, and frustrating, as I cannot use the viewfinder and even if I could, lots of shots would be much better using a wider-angle lens. Also, I am often kicking up silt with my wellies and the nicest shots often are just out of reach. So next time, I should really photograph whilst snorkelling. (It would be great to use an SLR in an underwaterhousing. I bought a much cheaper and much more cumbersome ‘underwater-camera bag‘ without remembering that my old, not-so-frequently-used-anymore Canon EOS 400D does not have a viewfinder. I am afraid this will make the experience less, not more, fun…) Anyway, the trick for now is to take many pics and hope some turn out all right. I like the ones with a water surface reflection best. The nicest one was a snakelocks anemone among corraline algae. Next, what is may or may not be Sea flax weed Stypocaulon scoparium. After that, the brown Divided net weed Dictyota dichotoma growing inbetween Discoid fork weed Polyides rotundus, a Bull huss/Nursehound/Large-spotted dogfish Scyliorhinus stellaris mermaid’s purse and a Spiny starfish Marthasterias glacialis. Probably more photos soon as the pools look by far the best in early spring.
