Beacon Island, WA, Transect G
Station 41C, 2-7m (about 22ft); 30% algae c. coral covering 100% of the bottom. Chlorophyceae - 40% - apart from perhaps fine filmentous epiphytes - which looked unhealthy - Caulerpa peltata & C. racemosa made up green algae, with Caulerpa spp. forming 90% of Siphonales (+2 dimensional form like yesterdays). the brown alagae comprise just about all the rest of the algae (60% with about 80% being small plants of Sargassum few large enough to have vesicles - which were round - stipes were very leafy. rest of brown algae (20% were Padina - not very large thalli. The red weeds were less than 5% - Asparagopsis coming in about 7m. with few hard short deep red forms on dead corals & underneath living corals. one small clump of Pterocladia - type of red under Aerofera mushroom - very few clumps of Codium mamillosum. Zonaria found - 1 clump. Collected Astraea tentoriiformus with large Hipponicids on it - semm to be different species to those from further south - radial grooves (or ribbing) more pronounced.

Station 41D 7-17m
bottom 100% covered by 40% algae c coral (few sponges & ascidians). Reef slope seems to level out at 50 ft (as did Bombie in Goss Passage). The brown algae dominated (90% with Padina about 50% - no very large thalli & 50% Sargassum - more luxuriant growth than in 41C. the Rhodophyceae accounted for the other 10% with Asparagopsis tpye at upper part of zone (& drift broken plants at intervels). A very few Thalli of Peysonnelia (flat rough red) - among Padina in sheltered positions & one plant (large) of Pterocladia found in very sheltered position. Under some overhangs were the iridescent gold thalli of a red which has been found before but probably not identified [sketch of algae] gold on top - red beneath gold sheen fades. there was a very small amount of Caulerpa peltata in this area. Collected some red anemones in 41D in a sandy hollow - attached to dead coral pieces in sand & when expanded some were about 4" in diameter.
41F - [stirred up silt blocked vision]
41E - [...] Collected a very large starfish on the way up - 41E. Liaster leachi - also colony of the coral Alveopora -which has a lovely polyps which stand well out from the skeleton & withdraw when disturbed, the skeleton is fragile & spongey - which crushes easily. Found a white anemone - about 4" in diamerter when expanded - with pink-purple tips to the tentacles (blue in deep water). Barry & Dennis collected some corals & sponges from bottom (41F) - with oysters & such on them.

Station 5A, 2-7m, upper slope; 100% cover. >50% (probably 60%) algae with coral. Dominated by brown algae - 60% Padina, 40% Sargassum - immature for most part. Crustose corallines in abundance in some places formed large thick clumps of blunt close-set branches. 
Station 5B, lower slope, 7-12m; about 50% going to 5% cover, about 10% of benthos being algae. Dominated by brown algae 80% with 80% Padina and 20% Sargassum. About 20% red algae - fine reds on dead coral, v. small amount of ?Asparagopsis probably Dasya. & v v small amount of Mesotrema ? - coarse network - on dead coral in v sheltered - deep red colour - no gelatinous edge there were large clumps (coarse network) of crustose corallines in the upper part of this station as in 5A. Green algae about 1% - Caulerpa peltata
Station 6, 42-45'; Bttom of hole - fine sand, about <5% covered in algae cover 100% of benthos. Sitting on the surface of the sandy-silt bottom (at 45') were small clumps of Boodleopsis with fine red epiphytes growing on it & directly from surface of sand & on small dead coral debris. There was plenty of drift algae - mostly brown fucoids. I didn't find any red tumbleweed but Barry did - not attached. The green alga certainly formed the bulk of the algae (about 60%) but the fine reds were spread over the greater area - probably accounteing for about 40% of the bulk.
Site 7, On what looked like a coral bombie from thre surface but was really the high spot of a curving ridge which shows out in the aerial photographs.

The red algae (5% of the flora) was about 100% Laurencia (large bunches of grapes). The green algae (5% or less) was all Caulerpa racemosa. Loisette got a large cf Mesotrema on the top of the ridge further to the SE - in about 1m of water in open- it was a yellow tan colour - gelatinous edging missing though the laminae shoed no sign of degeneration - though the network was very coarse.
Station 7B, supposed to be 7-12m (actually to 60' 18.3m); 100% cover, 30-40% of it was algae with coral. Algae was 100% brown with about 70% Padina or 30% fucoids of which 100% was Sargassum. However on the bottom - at about 60 feet the algae was 100% red with fine red filementous algae covering the sandy0silt bottom & plenty of red tumbleweed but noe attached.

Nothing on silty bottom - no algae or anything - except drift brown algae - algae & bryozoa on rocks at lower part of slope (95-90') werer covered in silt so that they looked like stalactites - could not even see colour. Dead corals (Euphyllia) stood up from bottom without any silt covering, showed white - about 10 corals seen in a very short distance from rope to boat - only one was alive. Only other species of coral seen was a Faviid which was [?]. Rhaeophyceae 20% Prostrate & short laminate 100%, Rhodophyceae 80% all.

We all went to Tatler I & Mangrove I. 1 species of ellobiid found in leaf litter at about HW, heaps[?] on around a piece of dead wood lying on muddy sand. There animals were patterned with a nwetwork of red-brown lines. Also with them were very small ellobiids ? mostly white - some pinkish, & also very small gastropods - horny shells about 2-3mm length. This last species was fouind in many sport searched - the v. small ellobiid in some other places searched but only 2 isolated individuals of the larger ellobiid were found other than in this place in about 2 spots seach from HWN->HWS. No Bembicium found alive - plenty of dead shells (found alive outside (yo N of) mangal, on rock outcrops with oysters). S. cuccullata found alive on outcrops of rocks to N of mangal & island as a whole (mangal on N side of island only of W end). None found on island. No oysters in mangal. Some Salicornia (. little) on outside of mangal, to N (island rock rose abruptly behind mangal).
We then went to Mangrove I - mangal is in the same relative position (ie on WW side of island) - There was a small Salicornia flat behind mangal at about HWL. Rock was at about HWL with channels & small caverns in it. Here there was another ellobiid - the banded form - probably a Marinula alive under wood & under stones at about HEL. The unbanded form was not found. - The v small horny gastropods were also found here but not the v, small ?ellobiids. There were also Bembicium under these rocks.

Went snorkeling in afternoon with Dan on reef flat W of Beacon I. Small oysters just below LWL Hyotissa (2 pronged passages) under ledge at about 2m below LWL. Examined small Gena which apparently had dropped its tail. The hind end of the remaining part of the foot was slightly split & acted in a bifid manner. The mantle extended up from the LHS as a strangely lobed very thin film with papillae on lobes which were lightly pigmented white. The mantle seemed to reach about half-way across shell - but not on to spine. In front of the LHS the mantle was folded to a forward projecting tube -apparently inhalant. On the RHS - further back there is a fold of the mantle forming a backward projecting tube - apparently exhalant. Photos - preserved specimen. Tested siphonal current with carmine suspension - current flow as expected. - v, small tentacles around ventral edges of foot

Went to lee edge of narrowing reef about opposite Split Island - about NE of Split Island in about position of Station 12 on Transect K.;
[...]O. tuberculata but all were fairly small. Most were on faviid corals (brain corals & 2 others) but Clay got a few from a ?Porites clump.
