25-VI-85 Tuesday
Got up at 7.30 after very wakeful night. After breakfast went swimming. Sam, Linda, Louise & I swam over area out from bay to E of station - out over N end of reef to west & along reef bordering Goss Passage. Students & Sam had sessions on the hookah[?] from jetty. During afternoon I organised Jayne & Bruce to do the transect project - out from bay on N side of island - I set up microscope - sorted animals. - collected some tube dwelling operculate worms - Serpulids? for Louisette - Worms orange -red - tubes almost papery & after fused together - collected from 1-2m in bay to NE side of island. Other "serpulids" on weed (Sargassum) - apparently not operculate.
26-VI-85
Went over to Long Island. Collected in pools on N half of island.
#1 - most northerly has recently been invaded by waves - apart from Austrocochlea & Bembicium no other organisms observed except for dead drift Sargassum.
#2 -Next pool south is notable because of the large amount of v. large Ulva plants - c thalli up to aobut 2x0.75m - in general of robust texture - some less robust (moribund) are holed. Amphipods; Opisthobranch egg strings (?Bulla); Austrocochlea; Bembicium; "Leptons"; Cladocerams (dark red); Serpulids ? under rocks; Chitons; anemones.
#3 -Pool at about centre of island on W side. Plenty of Bembicium; Austrocochlea; Amphipods; remains of Vermetids; crabs; orange-tan sponge under rock; orange worms - white bristles.
Went swimming in Goss Passage off SE end of Long Island. Collected chamids 1-3m for Professor Purcham[?]. Collected oysters. Chamids 2spp. 
(1) Shell white & mauve. Exterior of anterior aperture clear light brown with granules of white or cream. Interior & posterior part of & to this aperture is clear mud brown. Interior of posterior aperture dark brown round edges (c clear white tentacles) & orange (opaque) peripheral to that with white opaque granules at post end. Gills orange(opaque) internallu ? gonads. 
Used Patrick's telescope (tele-lens) to look at 1/2 moon. & Jupiter c 4 moons & Betelguese (2 stars).
27-VI-85
Felt ill so didn't go diving. Did lab work. Helped students with transect & salinity projects. Sam & Pat went out hoping to get to wreck site - too rough so they went to Coral Gardens area & dived down slope. Pat brought back a spondylid & 2 small chamids from 100' (slope of about 45° to sandy plain bottom). Sam brought back some vermetid shells from about 25' - narcotised few[?] serpulids.

Station Pelsart#1 PG#1
Burnett Island (This island is also called Fin Island on Lands Dept 1:100,000 off Army map 7290) Pelsart Group Houtman Abrolhos WA. sand, rubble, live & dead coral; 0-0.5m. I snorkelled with Loisette for about 3 1/4 hr. Differences in fauna around island appear to be more closely related to microhabitat there to degree of exposure on different sides of the island. However in embayment on WE side (N of little islet adjoining island) there is a sandy cove with Tapes litterata (though only freshly dead broken shells found - unpatterned & patterned with grey-black) & very many small oysters (? Dendostrea) on dead coral rubble, old metal, old plastic etc/ Same - but not so many of these same oysters were found in slight embayment near hut on SE facing side of island (near FW lands). Fred found a couple of Saccostrea cuccullata. I found a dead R valve of a larger D. folium. In the small "channel" between, the islet & the island to the NW of "our hut" was a diversity of molluss & cowries etc - not seen elsewhere. Most commonly found bivalve was Leptomya? (semelid) psittacus ? - none found alive - many dead, mostly dissociated. Next most common was Ctena bella of all sizes - most white - one pinking found - all dead taken. Few other lucinids (?Monitilara) few tellins of different species, very few arcids (Barbatia). a few live pteriids on Acropora; 1 small venerid; 1 mactrid (small); 1 Carditid (dead); live Septifer bilocularis; 1 dead pinnid?; 2 species of stomatellids; 1 v flat; trochid (Cantharidus ? 1 or 2 spp; 1 orange nudibranch; few large Dolabella? [sketch]; dead bailer - live egg mass; Euchelus 1 or 2 spp.; mant dead Turbo pulcher; few live many dead Tectus; Fair number of dead liotiids. Cerithiids extremely numerous particularly below sand surface. Island is edged in most places by small "cliff" about 2 feet high - only in a few places is there a shingle beach. On the NW and there is a lot of dead Acropora & a high diversity of living coral - though usually only small colonies - plus Xenia, several species of starfish . holothurians of one species of echinoid - under stones - covered with shell fragments. Further to the SE but still NW of the hut are some large patches of zoanthiids. Algae mainly basal parts of Sargassum spar spp & lots of red - mostly Laurencia with some filamentous brown(?) & patches of brown Zonaria to SW ride of island. Here there were also a little Caulerpa. In embayments sediment v fine - but coarse among corals. Some bivalves drilled (Nassariids, drupes seen) few broken (bald[?] chin[?] seen) many oclopes[?] seen - particularly off SW side. Note Check names on most recent.

6-iii-88 Sunday
We all went down the eastern side of the group sea being calm & day overcast & still. and made 2 steps off the eastern shore of Pelsart I. Conditions were calm with a slight swell so we made 2 dives on one tank - 1/2 at each station, 1 hour from 10.15.
Station PG#12 
off N part of eastern shore of Pelsart I, Pelsart Group, Houtman Abrolhos, WA. 6-25(28?)m - steep slope of dead & living coral down to sand bottom at about 25-28m. Upper slope deeply indented with gutters running vertical to shore. Spurs with heavy algal growth, Much articulated coral spp particularly in deeper water. Some Caulerpa peltata - deeper. fair amount of large leaved Halimeda near base of slope at junctions c sand. Increasing amounts of Sargassum spp & Ecklonia coming up slope & scattered bunches of ?Euchemna with thinner "branches" which are curved under at edges.

Not being able to go deeper than 8 metres because of short duration since previous dive Loisette & I were limited to upper slope which was more steeply sloping than previous station though without the abrupt change to a steep slope. It lacked gutters - the only one seen was a shallow gutter of the site of the outer wreck (not that in shallow surf zone).

6-iii-88 cont.
Late in afternoon Loisette, Gary, Randall & I went to Square Island, S of Basile I to collect. Loisette or I snorkelled & Garry & Randall dived with SCUBA. The others went to the pool in the reef between Burnett & Mangrove Islands (-still regarded as StationPG#1). The coral growth around Stick Island is magnificent - huge beds of staghorn corals of a variety of colours including mauve, blue & deep blue (richest colours I have seen). There were Montipora colonies of a variety of colours but other corals were sparse & small. As is usual in this type of habitat molluscs are scarse. However on dead coral - which became more abundant in towards island (we swam on SW corner (where there is a rubble spit extending intertidally)). - but dead coral is mostly in the form of overturned plate Acropora. On W side of island near SW corner there are shallow channels running about W&E. On the island we saw 7 seals (i being juvenile) which got excited but not enough to enter water to investigate.

Rain, thunder & lightning in evening. 
7-iii-88 Monday.
We all set off for the southern end of Pelsart Island but the motor of the jet boat broke down about 1/2 way to Square Island so we turned back & returned to Burnett Island being towed by the Zodiac. So then we revised our plans & Clay, Gary & Loisette went off in Zodiac to the Half Moon Reef about 1/2 way between the wreck site of the "Windsor" & the South Grounds in a more or less sirect line from Basile I between Sqaure I & Ship Rock. Subtidal -> 1.2m sand bedrock c brown weed Cystophora
Station PG#15
Half Moon Reef, Pelsart Group, Houtman Abrolhos - outer reef flat (about 250-500m from edge) sand on bedrock, Loisette & Clay collected. Barbatia; Isognomon (white); dead "Leptomya"; dead Ctena bella; Chloridoloma zeus[?]; Oyster.
While they were out Gerry & I went out to dive at at the edge of the reef off the free-standing jetties belonging to Burnett Island fishermen. Gerry used rotenone in deep pool just landward of the line of jetties & I swam there & out off the edge to about 12m (v fine silt) - Lytocarpus on cables, orange Pentagonaster.
Station PG#1b
Burnett Island, Pelsart Group Houtman Abrolhos, off NE side of island. drop off of dead & living coral to silt at about 12m. ie 1-12m, steep coral slope to soft bottom. dived 1 1/4 hour. 12.20 - S.

8-iii-88.
At about 8.30am "or a little later." Gerry, Flay, Nick & I set of in Zodiac for Half Moon Reef. Fred was to leave for Geraldton in the Fisheries vessel (?"Abel Tasman") when it called to pick up the jet-boat to tow it back for repairs. Loisette & Gary were to dive over the edge in front of the island jetties (ie Stn PG1). We went diwn the chanel between Square Island & Stick Island then on past Skip Rock to reef. After being carried NW by strong winds (seas were rough & trip very bumpy - I even fell overboard on one particularly violent bump. My back started to seize up with the jarring but fortunately we got into shallower more sheltered water soon after & all was well. The site where we eventually anchored was apparently somewhat to the SE of yesterdays' station. Apparently much of the fauna was different. We swam briefly around in the coral covered area ?80% cover of dead & living Acropora & few small colonies of other groups & then swam towards the reef crest where several large bombies emerged above water level. We could clearly see the southern end of Pelsart Island with its tower & much closer what seemed to be part of the wreck of the "Windsor". The majority of the collecting I did was in the zone of dead coral & exposed pavement with shallow mixed sand between the Acropora zone & the reef top. I did some collecting in shallower pools cut down into the pavement rock of the reef top - very abundant Septifer, Tectus, some Dicathais, Astralium, variety of mesogastropods & neogastropods (drupes, cones, etc). Oyters on bombies S. cuccullata with large barnacles. Gryphaeids (Hyotissa numisma?) under dead coral slabs. Many Tectus (but few Turbo) predated.

9-iii-88
Started packing early - ready on island jetty when carrier boat Southern Lady arrived at about 11am. Delivered fuel to 2 jetties on Jacksons Usland (collected Austrocochlea alive at one - same as our Stn PG#4 & one on "the Nook" (ie that little island between Jacksons & Newman) & also at one of the islands further south. Arrived at Geraldton about 4.30on unloaded - then went over to the Fisheries Dept. to organise gear etc. [Dinner etc, departed for Perth arriving at about 8pm.]

Wed 16-iii
Departed early for dive - approx. WSW of jetty where broken reef/weed bank is separated from reef proper - adjacent to break in reef. [sketch of diving area].
Plenty of small->medium O. tuberculata on isolated bombies (depth 2-4m.) in from reef. Fair number of D. folium under ledges of reef - particularly S of break, depth ? 2m.
[Travel to Geraldton]
Thurs 17-iii
[...] Greg came with us to dive on reef off Point Moore. Dived on inner edge adjacent to Point & out to boat channel into Harbour through Devils' Gate. Shallow sea grass or weed beds - diversity of weed (much Cystophora) - on flats. Reef was abundantly algal covered with holes to about 2m - edges were undercut. Plenty of crayfish - found only one oyster. Plenty of Bellostrea tentariformis, Marmarostoma pulcher, & few Ninella whitleyi (which I hadn't noticed at Port Gregory) & Tectus pyramis. Few Dicathais, v, few trochids on weed, plenty of columbellids on weed. Few malleids/isognomids on cove walls. A diversity of corals though colonies were not very large nor abundant. Went out to look at reef offshore for diving -  could not find sharp drop-off shown on chart. -appeared to be to within 5m of surface - kelp covered. Decided not to dive. [Collected luggage, had meals etc]
Fri 18-iii
[...] We launched boat in harbour & went out to Irwin Reef at N end adjacent to channel - spent some time looking around - met up with crayboat who said he would guide us to edge of reef - instead took us to shallowest part. Clay cut a rope which was around his propellor & they left. We decided to dive in this area to south of shallowest areas shown on chart. Clay & Charlie dived first - I was boaline[?] & then Clay came back & I went in. Magnificent country - weed covered - mostly Sargassium but holes & ledges everywhere. Top of reef was at about 6-7 meters & holes were another 1-2m. This is a sponge workers paradise - so beautiful under ledges - every colour & form- & also abundant ascidians. A great density & variety of coral in these dips & ledges, and very abundant O. tuberculata on almost all species of coral. Often the coral - faviids, meandrine. Turbinaria, Montifera etc formed plates - often on bases of holes. Areas around edges of coral were often sandy (possibly because of protection afforded by coral) & coral edges extended out just above this sand - where oysters (O. tuberculata) were found in this position, the coral & so the oysters was tipped up so that the lip of the oysters was up away from the sand [sketch]. Found 1 large oyster ? Hyotissa sp (2pp) & some ded & possibly 1 living D. folium in caves. V few malleids found in caves - not very many Septifer evident. Found 1 Haliotis elegans under a corallum of a ?Leptophyllia? - quite large. Saw - but didn't collect "Phyllidia" as at Pt Gregory - & purple white & roange & red nudibranch.
Sat 19-iii
Port Denison (White Tops). Port Denison -> Dongara -> Sandy Bay -> Jurien Bay [...]
Set off early to White Tops Reef - S of Port Denision & inshore from S end of Irwin Reef. Dived on SW corner of reef where chart shows greatest drop-off. However situation much less suitabel for corals etc & much more suitable for plants. To S&W of corner bottom appears to be a plain of sand well marked by ripple marks. <1' apart & running roughly in a N/S direction - very little evidence of infaunal bivalves - probably too mobile - certainly coarse sand. Back to N & E fairly steep slope from few low isolated outcrops - in places fair amount of coral - some fairly large bombies. Oysters sparse (nothing but O tuberculata found). Dead Dinassovica live Marmarostoma pulcher & Ninella torquata. Slate pencil sea urchins. No star fish. Fairly smooth Acropora. On upper part of slope - much kelp & fucoids. Went in to shallows where low swell breaking - snorkled - Clay found 3 mod large Hyotissa - no tuberculata. Very little coral except for Pocillopora & few small colonies in pools - rarely over edge. - Heliocidaris common. 
[Travel to Jurien Bay]
Sun-iii
Jurien Bay - outside
Early in morning, wind strong & uncertain, waited for it to drop - processed oysters (live). Went out in boat to outer reef - roughly north of Escape Island. On outer side is drop from about 15' to 40' with swell breaking on shallows. Anchored on drop-off just where swell was rising. I acted as boatman - while Clay & Charlie did first dive. I went in later (with Clay). - ledge heading to east- exposed rock with undercuts - broken into boulders - again marvelous for sponges & ascidians & also bryozoa - very little coral. Starfish - yellow with small black spots & Pentagonaster - slate pencil sea urchins. Found one small basket star on sponge - Clay found one on coral. No oysters. [Returned to process material]
Mon 21-iii
[Notes on morning activites, phone calls etc] 
Decided that there was no point in going further south. - no new species of coral turning up (rather reducing in diversity) & also density decreasing. Also oysters becoming harder to find. So decided that we would return to Geraldton & investigate possibility of going to Abrolhos. [Shopping for supplies/ travel to Geraldton]
Tues 22-iii
[Personal activities in Geraldton]
Wed 23-iii
After a reasonable night's sleep got up at 4.35 & managed to catch boat at 5.00am. Dived off reef beyond Station's toilet - twice in afternoon. 
Thursday 24-iii
Early breakfast - Carrier boat in at 7.00am - began dive off toilet at about 8.30 - went straight down & to east - quite different from area to west - steeper slope - much larger fan-shaped colonies of Acropora & Pachyseris. Plenty of Hyotissa (probably H. hyotis though juvenile) & also dark[?] shelled D. folium though many were dead - not bored - not crushed. In early afternoon snorkled to SW of island in lagoonal area off point & S. Bay - over to edge of deep hole - small Trochus (Trochus) sp on dead staghorn Acropora or among dead bases of living Acropora - various spp. Plenty of pteriids on Acropora spp - live (spat also found). Very few Dendostrea sp. on dead Acropora - or else (or as well as) very hard to find - all found were very small. Favites abdita, Montipora, Goniastrea pectinata, G. australiensis, Cyphostrea, Favia. 
Fri 25-iii-83
Went diving down sleop into Goss Passage about 8.30 or so. Looking for Hyotissa sp. (2 promyal passages).

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.

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.

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.

The only place wgere they were abundat was on the dead top of a v large Acropora colony 0 90% short grapes & 10% purplish Laurencia. Laurencia (Trochids from this).

Station K15, 95-90', very silty bottom at 95' with lower 5' of slope. Cover of 0-40% from 95' to 90'. Of which >95% algae with bryozoa - very few corals & very few sponges. 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.

[Notes on travel to Beacon Island]
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.
