Volume 1 - 1937 - 1962
Volume 2 - 1962- 2013
 

Accommodated in Caraven No 2. - got settled, Clay & Gary pumped up tanks, Loisette & I went through gut contents of fish caught by locals about 15km off coat. These included a Queen snapper & so guts yielded a variety of molluscs including Pseudostomatilla, Gena, olives, bubble shells etc. We also collected a few very small urchins like those Loisette has recieved previously from Esperance area (Alan Longbottom).
Wednesday 29-IV-87
Left caravan park about 8.30 - bought fuel for outboard motors of Sepia & launched boat off beach south of main anchorage. Conditions fine & calm in shelter of reegs but moderate swell offshore.
Station #1 Approx 32°31.4'S, 115°02.6'E, seaward of reef between Cervantes Islands - low rocky reef in seagrass & algal beds; 5-6m. Visibility poor. Dived with Loisette in 9.50 out 10.45am, strong surge. 
Variety of algae great - mostly reds and greens (About 5 species of Caulerpa). Dominant form probably Laurencia spp. with many Gelidiales. Agal growth lush. Sand pockets in rock crevisces. Campanile abundant & live; Turbo jourdani - few seem live but many seen dead - including places where opercula were like gibber stones covering bottom.; fewer T. pulcher & T.; one operculum of Euninella sp found v few dead shells of Phasianella. Dicathais present but not abundant as was Agnewsia. Euplica conspicuous by its absence. Few Tentimitrella on weeds. Plenty of dead but few live Scutus - some large. Plenty of dead Haliotis elegans & H. scabris but no live ones found. Many Heliocidaris, fewer slate pencil urchins. Petricia only starfish found. Very few fish seen & then only weed fish. Diversity of molluscs apparently low. few chewed Lassariids, few Dicathais. few Hipponyx. Most common bivalve was Arcopagia !victoriae with a few broken Septifer shells. No lucinids seen. No trochids seen, few v dead creepers (Cerithium vertagus?) (with with nodules) seen. 
Stn#2 approx 30°30.8'S 115°02.8'E. WSW of Thirsty Point, Cervantes, WA. 0-3m. Seagrass (Amphibolus & Halophila mainly) beds & low rocky reef with algae, sponges & ascidians. Seagrass beds show signs of past blowouts but plant growth has regenerated with Halophila & species of Caulerpa dominant. On the rocky reefs red algae were dominant with large dense patches of Caulerpa? longifolia. Locally there were reasonable growth of coral & articulated (hydroid-like) orange bryozoa. The molluscan fauna was muchas at Stn#1 but fewer T. jourdani. Some very large, thick & hoary shells of Scutus were found. Haliotids (H scalaris & H elegans) present but not so abundant. 
Thursday 30-IV-87
Rain overnight - winde moderate - forecast of 35 knots during day. Departed Caravan Park about 8.30am - sea too choppy with moderate swell to plan diving - too turbid. So went dredging to south of Anchorage between 30°30.4' & 30°32.2'S, 115°03.1' & 115°03.6'E.

Processed in afternoon & evening. No further work possible because of gale force winds from NW.
Friday 1-V-87
Gale force winds & rain all night - no point in going diving (too turbid) no hope of dredging (too rough). Went S of Cervantes to Hansen Bay to have a look but wind had swung from NW to W & so this area was no longer protected. Then went N (by vehicle) towards Black Point - couldn't get right through to Black Point so went beach collecting between Twin Banks (ie N of Cervantes Marker Beacons opposite southern half of Sand Drift (approx 30°28'S).

Processed all afternoon. Far too rough to do further work.

Sue arrived with Andrew Williams about 1.30pm - had lunch & she & Gary departed about 2.30. The rest of us spent the afternoon sorting - processing the mornings catch. Weather moderating - fine - cooler. In view of variability of molluscan assemblages over small areas inshore, decided to concentrate on this area & perhaps Jurien- Sandy Head for most of trip.
Sunday 3-V-87
Cold overnight - fine but high cloud - forecast of easterly einds tending to south, slight seas, mod swell. Went out near to outer reef but too rough - too much swell - so went to SE end of Southern island of Cervantes Islands. Chart showed area to 7m but we could find areas of only about 3m depth. Amphibolus beds with v little Zostera near reefs & v little Halophila in blowouts. abundant epiphtic algae (mostly red but large bunches of Cladophora?) & abundant & diverse red algae on sides & top of reefs which rise to about LWS & have vertical sides with some undercuts (sandy floors) near substrate level. Swell was still evident & siltation on algae etc was obvious.

Spent rest of afternoon (overcast) & evening sorting & processing - clouds cleared during evening - cold.
Monday 4-V-87
Fine morning - not as cold as yesterday - forcast as yesterday at 9.03am. Wenr out to Outer Rocks north of Cervantes. Swell ha decreased & wind was from the east. Decided it was calm enough to dive to the west of Outer Rocks Loisette & I dived first.
Station #5: W of Outer Rocks. Cervantes, WA.  approx. 30°26.5'S 114°59.1'E. Depth 12-16m. Mobile Sand with rocky reefs covered with algae, seagrasses, sponges ascidians etc. In 10.55am out 11.40am. Sand was very mobile - no seagrasses or algae. Rocky reefs were about 1-2m high above substrate. Algae diverse & abundant - kelps, Amphibolus  (serrated edge of young leaves), Posidonia Caulerpa spp (mainly scalpelliformis) numerous reds including Eucheumna & a Siphonodadiales [sketch] pinkish red but mottled - pustules on outer part  also Siphoniales few (green) [sketch] (Martensia) twisted reds (?browns). Tops of reefs with small but colourful bright pink, sulphur yellow etc sponges & ascidians. Sides of reefs covered with simple but usually compound ascidians, sponges (sponge paradise) hydroids, bryozoans (curly orange, brittle perforated dar grey, lacy orange-pink etc). No pycnogonids seen (or later found) on curly bryozoan colonies but a couple of large bright orange, very active pycnogonids seen on & collected from bunches of red algae. Swell was strong- continually swished backwards & forwards. particularly in crevises between reefs. (one with overarching "bridge"). Very few molluscs found (or seen). No urchins; 1 species starfish (yellow) Austrofromia polypara. Live: Malleus; Turbo pulcher (one crushed); Dicathais; Barbatia; Phyllidia pair; & very few dead shells in shifting sand. In going though lumps of encrusting material (collected for hydroids etc) small but very colourful Phasionella ?ventricosa with red animal (& sometimes red shell) were found - anterior end of foot acts as if bifurcated (see photos of similar animals from outside Gordon I - Mewstone Rocks etc).
