Sat. 16-X-76
J. Chambal[?]-Gasper, J. Campell (on contract to MMA) already in Kununurra. Ron, Daryl and I went to Diversion Dam; C.B., B.R.W., Dan K., T.D., B.H. went to Lake Argyll. I collected dead land & FW molluscs from edge of lake. [Left Kununurra by plane] Arrived Mitchell Plateau mid afternoon, met by Mr & Mrs Street, Laurel Keller, Fred Wells, Mike Ellis, Laurie Smith, Dr. Lukocius[?] & Chris & Maurie from AMAX base. All new arrivals + WAM party drove to Warrender - Also Salem[?] & John Kithby[?] camped at Jump-up. Steets & party camped near Base Camp. Set up camp (14°34'05", 125°50'20") on S side of Walsh Point about mid way along from tip of point to mangroves. (Grid Ref 063874 Sheet 4068 Series R611 "Warrender")

Monday 18/10/76
[Diary notes; Sorted mud samples. W5 - Small Bag 20. W4 - Small Bag 17. W2 - Small Bag 8 (not quite finished). Maurie brought back some Chamea sp. specimens - I ate one - v. strong oyster flavour.]
Tuesday 19-X-76
Sorted mud from Stn W3 (W3 Small Bag 11) moved into zone 1 of mangroves: W6 opposite W3.
W6 Small Bag 24: Ceriops tagal Mangrove species A: (Max size ca 9ft (31 m. hi[?])) 123 specimens (no pneum. (buttress roots)) counted in the 5m square.
Avicennia marina Small Bag 23: mangrove species B: 11 specimens (pneumat. (no buttress) (Max size ca 13 ft)) counted in the 5 m. square.
Small Bag 18: living snails from site. Cerithidea sp. from stems of trees, usually hanging by a mucus seal from the central part of the outer lip. Juvs usually in crevices of roots and stem base. Littorina scabra on leaves. Nerita lineata - 1 only.
Small Bag 6: Mangrove sp. C: Rhizophora stylosa 2 specimens counted in the 5m square. (no pneum.; no buttress; with prop roots). Lichen on them. Max size about 11 ft.
Small Bag 9 - dead molluscs, live crab, live sipunculids. hole 1/2x1/2m x 30cm.
W7 approx. opposite W4.
Small Bag 22: Ceriops Tagal Mangrove Sp. (= ? bag 24) 32 specimens counted in 5m square. Buttress roots; no props or pneumatophores. (NB. small ellorbiids from hollow trunk.) In this square there is a meandering gutter about 6-10" wide + 2-3" deep.
Telescopium in the gutter plus dead sells of Cerithidea occupied by hermit crabs - 1 with a spider.
Holes with roofed, nearly horizontal entrance tunnels, about 2" diam.
Molluscs in Small Bag 19. Molluscs from mangrove of same species (just outside square) in small bag 22 with mangrove specimen.
Found a mangrove stump- live tree - in which the base of the stem + the buttress roots was riddled with a Teredinid. Sample collected + put into bag 22 - it was a tree just outside the square. Chopped around inside the square and found that nearly all the larger trees (i.e. more 4" stem base diam.) contained teredinids. [Diary notes on return to camp].
W7 (cont)
05.mx0.5mx0.3m 
Red species of Uca, small crab
Small Bag 0 & 25
lots of sipunculids, dead molluscs,
crab outside sample hole[?] ? female
Bag 16
(?Ostrea sp.) oysters on dead log outside W7 area + Neritina?
Found live ellobiids (approx. opposite (W of) W3 & W2) at upper edge of mangroves which grow adjacent to hill & supra mangrove flat. In this area around upper reaches of Port Warrender Bay the elevation seems to be slightly lower than on general supra mangrove flat and consequently wetter mangroves extend round this area ( supra mangrove flat is somewhat a misnomer - though  not when elevation is considered). Ellobiids were near upper limit of these mangroves under litter (flood litter?) of sticks and leaves - often buried in soil (mud with larger grain size & more humus content) than mangrove flat mud on supra-mangal flat on mangrove zones proper) - 2 spp. E. aurisjudae ? Cassidula angulifera.

22-X-76
[Collecting in mangroves just west of camp in oyster zone, Fred and Clay went to Point to start rocky intertidal intersect]. All oysters seem to be Saccostrea commercialis [descriptions of oyster habit and morphology given]. At this time - about 6.30-7.00AM the oysters were being bored by two predatory muricids (specimens of predators & oysters with bore-holes taken) these oysters were in upper intertidal near HWL. [Further descriptions of oysters and predator ecology]. Within the oyster clumps were mytilids (2 spp) Isognomon (round species), a very few arcids, ?Perma[?] sp., nerities, a littorinid (Barbicium type). chitons ? 2 spp., polychaete worm, crab. Under rocks below boulders & in contact with mud were small live ellobiids ( ? Marinula type) & deal shell of a larger ellobiid. On rocks & in dead oyster shell were a few specimens of Enigmonia rosea. Small opisthobranch (? Pleurobranch) on surface of oyster clumps.
W14 in from W2.
1 specimen of Rhizophora stylosa, max height 50'. Onchidium, Nerites, Littorina scabra, no molluscs in mud, only 1 worm. bag. Littorinids up high not sampled.
W15 in from W14.
Molluscs & mangrove sample in bag 11/2. Littorina scabra, hermit crabs in dead Terebralia shells. 1 mangrove 20' thin pointed leaves smooth bark many thin pneumatophores - nerites under dehiscent bark, smooth bark Avicennia marina (large leaf), 2 mangroves 25' rounded thick leaves, ? pneumatophores & perhaps thick pneumatophores, large star[?] fruit - flaking bark.

Beyond seaward edge of mangal - beyond mangrove trees, mud sloppy[?] - sink to hips (photo) - few pneumatophores extend out from Avicennia marina. Bag 115, no standard sampling nerites in it by mistake - belong to W15. This zone was devoid of trees but had some mangrove roots [?] pneumatophores (Avicennia ?) extending a short distance into it. This zone was abandoned as unworkable but previous zone of W15 was divided into two - the landward section where W15 was located + a zone right on the edge of the mangal where ellobiids & red opisthobranchs were common & tree diversity lower.
W17 back in from W17.
On very edge of mangal. Bag 116, 1 specimen Avicennia marina, 3', fine[?] pneumatophores. 1 specimen mangrove 18' large stubby pneumatophores, Sonneratia alba, soil sample excavated only to about 10 cm. Many neritas, Bembicium + littorina + mytilids (ribbed) under dehiscent bark - many littorinids up high in tree not sampled. [Summary of difficulty of work conditions given].
23-X-76

Took Barry W. to show him area with many Telescopium - took photos of these & of red opisthobranchs. Collected dead shells on beach - collected live Murex (Naquetia?) permaestus on oysters & also on dead log. [ Descriptions of Murex specimen and of oysters (sp. not specified) in mangroves, 2 spp. of Onchidium seen and photographed - large on by BRW, small ones (grey and green) by SSS.

24-X-76, Sunday.
[Fred went to Point to do rocky shore transect and SSS went to collect & do oyster work. Description of oyster zone ecology and species given, summary of species observed/collected follow]
green sponges, many large Murex (varicosus[?] ? cervicornis ?), M. secunda, one dead & one living Hyotissa, no Saccostrea, a few number of nudibranchs - dark red-black & white - seemingly mating - a pink one laying eggs - little aeolids like those from Kendrew in patches, 2 urchins, one starfish, a few corals - some[?] diversity none abundant except for a Plesiastraea type.
Up from this zone was a zone of large barnacles - mostly dead & oysters - few of living & dead Saccostrea. Murex varicosus (found lower than main oyster zone), thaid shells containing hermit crabs. Up from this was a zone of abundant oysters - spiny when young - not strongly ribbed - S. commercialis. Chamids, Pearl oysters (P. albida ?) + Septifers occupied the crack & crevices & also attached between oysters. Arcids (3 spp.), Cardilids & tube worms, Haliotis varia & fissurellids (Tugali?), Trochids (Trochus lineatus? & Pantherides[?] sp. ?), columbellid, few reitids, occasional Onchidina[?], Polychaete worms (Nereids & Lepidonotus) were common among & under oysters. The only muricid common in this area was the purple mouthed drupe with rows of fine scales. Hermit crabs were common especially high in the oyster zone. Lepsiella, Bembicium.
Station W22; Rhyophora zone in from W4. 1 large tree Rhyzophora stylosa, 30' high, + roots from another 3 trees just outside area. 1 anemone not taken (too difficult), brown fiddlers c. red claw.

[Notes on measuring sizes of zones F to B]
25-X-76
[Description of work done on Point Walsh for morning tide, summary of species observed/collected follows]. Area below green sponge zone exposed - red sponges instead & red gorgonians, some red sponges (leaf like from) had red nudibranchs eating them. Did not see as many nudibranchs or Murex varicosus as yesterday. Got a few Hyotissa, also Chlamys senatorius ?.
[Description of work on oysters, from the area south & westwards from the tip of Point Walsh, extensive description of thaid? "typical of the oyster zone" and a "large thaid seen yesterday" distribution and feeding habits, other species noted include; Isognomons, stripe drupe - like an Agnesia, no sign of Murex permaestus alive - only one dead shell].
Station W25, in Rhizophora zone opposite Station W5; 1 large Rhizophora tree & large branches of three others, 30', Murex permaestus.
Station W 26; 1 little white bivalve outside area. 2 Sonneratia trees, 18 feet.
This completes the works on the sectors.
26-X-76
[Description of work and collection done at at Walsh Point] tide was very low - below the green sponge layer to the red sponge zone. Collected Ovulids on pink & white & on red & yellow gorgonians. The most common species was a large white one - perhaps the same as the two colour form of gorgonian & a yellow-shelled species (one animal) on the pink & white gorgonians. Shore gorgonians were half exposed at low tide. Collected quite a few Hyotissa sp. specimens on boulders in green sponge zone. Examined oyster zoning N. of barge landing. Took photos (Ektachrome film) of oysters & predators from upper limits of oyster zone to lower limits. In upper area only large thaid was feeding though.

9.45am: Boat Ramp on Walsh Point; all mangroves out of water by about 8', about 2 1/2 - 3' vertically. Mangroves south of north corner of Walsh point out by about 20'. North corner of Wash Point only Zone A out. Around N. corner of Walsh Point Zone A -> B out. 
9.55am: McG 1, N corner of MacGregor Point; more[?] exposed - Zone A -> B out of water, mangroves 20' out (4'-5'!?).
Station McG 2, S. corner of MacGregor Pt; mangroves 30' away from water at about 10.10am (ie about 4'6" above water level). Zone A not much settlement of spat? No surviving oysters - good settlement mytilids - no survivors? algae 3-4'6" above water level. limpets 2 spp. large number of thaids in crevices (like Malcolm Island) & below stones above A (Typical of exposed Point conditions). Zone B 3'-> water level & [?] below stones in A, lots thaids. Zone C below water level & below stones in B, no large oysters. Small neritas - no red mark. No orange plate neritas, no oysters in mangroves. Photo 19 on B&W.

Just N. of W. end of cliffs & vine thicket above & around Daryl's old camp, & with N corner of Walsh Point bearing SSE; Mangroves Aegiceras, Aegialites, Avicennia to within 20' of water (about 11am). Oysters on Aegiceras & Aegialites trunks most if not all dead (small juveniles & spat[?]). Photo looking SSW (High speed Ektachrome shot 1). Much better settlement of oysters than further N. but no large ones (>2cm) surviving. Photos HS Ektachrome 2, 3 & 4. Littorinids on Aegiceras tree from bottom in oyster zone A (B&W small form) up through top of oyster zone A to above oyster zone B (yellow form). No obvious settlement of smooth mytilid on rocks or trees - oysters more densely settled & cup shaped.
McG 4; Oyster Zone B->C out of water 11:30? parts shaded. 
McG 5, Aegiceras, NNW of W end of (ie slightly N of NNW of) cliggs & thicket near Daryl's camp. - mangroves 20' from water, Zone C, 11.30? large oysters most dead. Zone B, large oysters most dead no mussels.
