The tide was bad (i.e. low and too early to catch it on time), the water was cold and it was very windy but it was good to go for a dip this morning. I now have a different strobe arm which makes it easier to position my strobe, which has often been tricky. Time for some macro practice. The photos are not that special but I hope interesting enough for you blog readers! Above a Peacock worm Sabella pavonina sticking out of an abandoned piddock hole. Below a common Hermit crab Pagurus bernhardus, a Grey chiton Lepidochitona cinerea, a very small Dahlia anemone Urticina felina (note the warty, adhesive column) and some Daisy anemones Cereus pedunculatus.
It has been a while since exploring the rockpools, as the weather has been pretty horrific. However, I had a good go last week and this weekend. Although quite bleak, there was no wind and no rain. The water is getting down to 11 degrees probably (I have not measured it), so pretty chilly. There are quite some solarpowered seaslugs Elysia viridis on the Codium seaweed but I did not manage to get any good photos. In fact, I am still struggling a lot just getting the strobe to properly light up what I am aiming to photograph. A bit frustrating but that is why I keep practicing. Above a pill isopod, probably Cymodoce truncata (with the fringing hair on the rear uropods indicating it is a male). Below, a tiny Gem anemone Aulactinia verrucosa. There are a lot of small Daisy anemones Cereus pedunculatus amidst the Coral weed, they look brownish but when you zoom in there is some blue as well. Finally, a Netted dogwhelk Tritia reticulata, which are very common and active in the rockpools. Cold but always nice to be in the water. Luckily I emerged right on time when I saw my Sainsbury’s bag with glasses, car keys and phone drifting away due to the incoming tide!
Some photos from Last Sunday at Castle Beach in Falmouth. Above, the periwinkle Littorina littorea, which aggregrates in great numbers on the upper shore. Below, three echinoderm cousins: a Cushion star Asterina gibbosa and a little Sea cucumber Pawsonia saxicola with a Brittle star in the background. It was the first time I saw this beautiful colour variant of the Risso’s or Furrowed crab Risso pilipes. More common is the very similar Montagu’s crab Risso hydrophilus, there are usually 5-10 individuals under a single rock. The small ones especially come in a range of colours that make them excellently camouflaged against the pebbles. Next a juvenile Shanny Lipophrys pholis, a detail of a Corkwing wrasse (I could pick it up, that is how low the tide was) and a shot of the beach, showing the versatility of the mzuiko 60mm lens.
Some pics from today at Flushing Beach. Above, a pair of Green shore crabs Carcinus maenas, below two Furrowed crabs Xantho hydrophilus. (I probably should have gone for a whole crab series, as I saw several other common species…) Instead I took loads of random photos, of things that were 150 mm to things that were only 5 mm, with varying success. For instance of a Painted Topshell Calliostoma zizyphinum on the invasive Bryozoan Watersipora subatra. Also the underside of the urchin Psammechinus miliaris, showing its mouth (Aristotle’s Lantern). Photobombing top left is the commensal worm Flabelligera affinis (which I noticed as well the last time I took a version of this picture). Bit random but it was fun practicing. It actually is more difficult to take photos abovewater compared to underwater due to the glistening and the awkward position kneeling on wet gravel/rocks. Next time I might try a tripod (ideally remote flash would be used but I do not think I am going to invest in that). Btw, if you are on instagram, I also post pics as @an_bollenessor.
Another Silver Steps shore dive with @shannonmoranphoto and her fellow student Chris on Friday. The conditions were not as good as last time: low viz and a bit of a swell. I had set my camera to a longer focal range to try to take pics of cuttles or larger fish but that did not work out (with better conditions it still might not work out!). I could still shoot macro so that is what I did. Above to Devonshire cup corals Caryophyllia smithii. Pretty decent, but I know I can get a better close-up; I will try again Monday! I will have another go at the one resident Cray (or Craw) fish, which lives very shallow. I will also try the Twin fan worm Bispira volutacornis again, as I think a shot filled with just the fans (and not assorted bits of seaweeds etc) could be really nice. I might try free-swimming fish if they come close, as did this Poor cod Trisopterus minutus. Below some before- and after postprocessing. Just the jpegs in Windows Photos, nothing fancy. A bit of cropping, increasing clarity and contrast works wonders. Only when I have a really good photo I will invest time processing raw files in Photoshop. First the best photo of the dive: a Black-faced blenny Tripterygion delaisi (a female or possibly a non-breeding male). Next, a common Edible crab Cancer pagurus and finally a Twospotted goby Gobiusculus flavescens.
These photos are from a couple of weeks back; since the weather has been hideous most of the time I have not been out much since. More practice with the m.zuiko 60mm macro lens abovewater. Above a small Strawberry anemone. Below a small Cushion star Asterina gibbosa and my finger tip for size. Below that the hydroid Candelabrum cocksii and an Idotoea isopod species (there are several common Idotoea species but I have not paid much attention to them yet I must admit). Finally, the adorable Worm pipefish Nerophis lumbriciformis which is common and usually found in small groups under rocks (I have never seen them underwater as they are small, slow, well-camouflaged and probably hidden most of the time). Definitely will try to get some more portraits of these lovely fish!
I did a little ‘recon’ last Sunday in beautiful St. Agnes on the north coast but my timing was a bit off (the tide came in, with sediment getting suspended and the water becoming super-oxygenated, resulting in lots of bubbles on the wetlens). Luckily, this Thursday with no wind, the sun out and low tide, I had the opportunity to nip out again: awesome! Trevaunance Cove has a small beach, with rock pools on either side, I chose the Trevellas Cove side. Coincidentally, Shoresearch Cornwall (facebook here and here) had a survey and so caught up with Matt and Adele as well as Thomas from HydroMotion Media who I had not seen in a while. The north coast is quite different from the south coast I am used too: more exposed and this site for instance had none of the long Thong weed and Wireweed which dominate Castle Beach. The pools are also wider and in parts have a rocky, gravelly or sandy bottom. One spot had a considerable rock overhang, and I probably spent a full hour alone just at these six meters or so as there was so much to see. With the tide out, it was only about half a meter deep, with rocks encrusted in purple corraline algae, pink and orange sponges, bryozoans, tunicates and red seaweeds. The over-under shot is not particularly great but gives a rough impression, as do the two underwater shots (note the mysis shrimp in the last photo): There is a great diversity in red seaweeds, but I find these species quite hard to ID. The red rags Dilsea carnosa look pretty ‘ragged’ in Falmouth at the moment, but in this shaded, high wave energy spot they looked very fresh (first photo). I made a lot more photos but I was really struggling, as the bright sun reflected on the sand, with the seaweeds sticking out from the shaded overhang, such as Sea beach Delesseria sanguinea. The third photo give a good impression of the beauty of this habitat. Black scour weed and Discoid fork weed manage to scrape around in the shifting sands. Serrated wrack hangs and drips from the rocks into the pools below.Apart from the mysis shrimp in the water column, very large prawns patrol the rock surfaces and Edible crabs, Velvet crabs and Spiny squat lobsters hide in crevices. The prawns are curious and really beautiful. Most spectacularly, I found a large lobster in a cavity and at one point had a small lobster walking over to me: Many fish could be spotted as well: Topknots are common (you can just about see one glued to the rocks behind the lobster in the photo above) and there were a couple of big fat Tompot blennies around as well. Dragonets patrol the sand and are very well camouflaged (and hard to approach). A juvenile fish was hiding on and in a sponge; I first thought it was a juvenile Black-faced blenny Tripterygion delaisi, but in subsequent facebook correspondence thought of a Montagu’s blenny Coryphoblennius galerita (very common here) but then settled on a little Tompot blenny Parablennius gattorugine. This would have been a very good subject for a proper macro-shot if only I could get to grips with my strobe! In general this was a great place and time for fish. Apart from the topknots, tompots and Montagu’s blennies (juveniles were abundant, present even in the tiniest pools), I saw sand eels, corkwing wrasse, a pollack and horse mackerel (both a bit lost in these shallow pools), corkwing wrasse, shannies, sand gobies and rock gobies. I thought I spotted a Giant goby, but this turned out to be a very large rock goby Gobius paganellus (thanks Matt Slater). After the large goby photo, a tiny Rock goby (I think), a Shanny, a Cushion star and Snakelocks anemones. I cannot wait to get back to this beautiful site, but will need to wait a bit for the next good tide…
It had been over two months since I last went snorkeling at my spot in Castle Beach. Although I did go on two boatdives (with no photos to show for), let’s say the work-life balance was tipped in the wrong direction. However I had time for a low-tide snorkel this Saturday and it was great to be back in the water, with a Curlew as my only companion. It was the plan to practise strobe photography but unfortunately I did not manage to get my settings right and I was going nowhere. As this is an activity that is supposed to be fun, I decided to ditch the strobe and stick with natural light. Fish I spotted were Ballan- and Corkwing wrasse, two-spot gobies, tompot blennies, a fifteenspined stickleback, a dragonet and sand eels: It is pretty much the worst time in the year for seaweeds but the pools are still quite pretty. The first three photos give a general impression of the seaweeds, including Thong weed, Harpoon weed and Irish moss. After that: Codium spp, Juicy whorl weed Chylocladia verticillata, a big plant of healthy-looking Hairy sand weed Cladostephus spongiosus, withered Red rags Dilsea carnosa and Dulse Palmaria palmata growing on a kelp stipe. I called it quits after two hours. On my way back I noticed an abundant green algae species I had not seen before. David Fenwick identified it as actually being a cyanobacterium rather than a seaweed: Rivularia bullata, interesting! Hope to do a lot more snorkeling before it gets too cold…
Today I went for my final dive this year, again with Atlantic Scuba, and this time to the wreck of the SS Volnay (see here and here for background). Just off Porthallow on the Lizard peninsula, at around 17 meters (at low tide) lie the remains of this WWI casualty, hit by a mine and dynamited twice after (probably to get rid of unexploded shells), so she is mostly flattened. The boilers still are largely intact and are very impressive though, see the first not very-well composed shot (should have used my buddy for scale); note the white Dead man’s fingers. This dive would guarantee two ‘lifers’ for me, first the European spiny lobster (or Crayfish or Rock lobster) Palinurus elephas, which seems to be getting more common the last few years. Indeed, we did not have to look hard and saw the long antennae sticking out of nooks and crannies everywhere (see also the Devonshire cupcorals on the second photo). Second, and the main thing I was looking forward too, were the Pink sea fans Eunicella verrucosa. I had found some pieces of this gorgonian washed up on the beach before but never seen it alive. Luckily, at this site it is a common species (many juveniles, unbranched little ‘sticks were also present). I took a whole bunch of snaps and edited the jpgs in the standard Windows photo viewer (I keep the RAW files but need to find some time for proper post-processing). Just reducing highlights etc does wonders, but what I really need to do is be more clever with my camera settings in the first place. My New Year’s resolution will be too think ISO and aperture and not lazily rely on presets. I might also invest in a strobe capable of manual control (thanks for tips kelpdiver @dpreview!) High time to up my game! Below, three of the sea fan photos that came out best. Lastly, a nice new species for me: Trumpet anemones Aiptasia mutabilis. My four recent dives with Atlantic Scuba have all been great; a boat full of friendly divers leaving from just down the road in Mylor, skippered by Mark Milburn who has a very deep knowledge of the area. Todays dive with buddy Jan was very relaxed but I still learned a thing or two. More diving next year! P.S. Mark Milburn just published “Falmouth Underwater: a Guide to Marine Life, Wrecks and Dive Sites around Falmouth” (available here) which I highly recommend to anyone planning to dive or snorkel in the area!
Finally, time for a (solo)dive last Saturday, at probably the most accessible local site: Silver Steps in Falmouth (you can just make out the steps in the photo above). The sun and high tide had attracted quite a lot of other divers too, including University of Exeter and Falmouth University students learning the ropes. I was very keen to get in the water and take photos but my approach is probably not the best: I just shoot whatever happens to be in front of me. Better results could be obtained to specifically look for macro subjects, to stay in the water column and search for jellies, befriend the Ballan wrasse or stay put in front of a Leopard-spotted goby hide-out (or check out seaweeds of course). I’ll do one of these things next time, for now, some random shots. I spotted several Spider crabs; these are always shy and try to quickly retreat, except for one. This big crab came after me as soon as we spotted each other. I should have tried more shots, as unfortunately he did not fit the frame. You can see in the short movie why I didn’t!
The viz was not great (I find it hard to estimate it in meters though). In the water I noticed a small hydrozoan Leuckartia octona. The underside of some wreckage harboured Light bulb sea squirts (see previous post) and some were predated on by Candy striped flatworm Prostheceraeus vittatus. (I brought my new LED light with me to help bring some colour out but I just ended up with combinations of glare and shadows so stuck to my normal natural light pics.) Next, a curious Ballan wrasse Labrus bergylta. Finally, some not so clear shots that nevertheless give a good impression of how tall the invasive Wireweed Sargassum muticum are growing. Hopefully more dive posts soon!
