Thursday dawns with good weather so we aim for 2 dives catching the tide first thing with a 6am ropes off followed by another dive early afternoon.



We'd spent a good chunk of time on wednesday reviewing video and stills and this let us improve our map. Being able to work through the video actually allowed us to spot certain items that might have been overlooked on a dive. By also including shots of the lines and markers we'd installed it was also easier to ensure we had some accuracy. Dive teams and objectives were

Team 1 - Al, Clare, John Kendall
Video South and south east assisted by one of the HMI lights

Team 2 - Andy, John Grogan, Rich, David
Head west and north west with video and stills

Team 3 - Rob, Osama, Ricardo
Head north east and lay new zig zag line to fill in a blank space on the map

Team 4 - Joe, Gareth
Investigate bilge pump and area under the deck in an attempt to find specific features which might help id the wreck

We got some more stills and video, couple of examples are below





If any of the guys would like to post a personel view of what they acheived on this dive that would be great.

We chilled out on the surface for several hours and had lunch before getting in for dive 2.

Team 1 - Al, Clare, John Kendall
Video north and north line assisted by one of the HMI lights

Team 2 - Andy, Rich
Head north west with goal of adding line

Team 3 - David, John Grogan
North west line with goal of finding Capstan and surveying

Team 3 - Rob, Osama, Ricardo
Perform survey of South and south east lines.

Team 4 - Joe, Gareth
Concentrate on hull photos



Overall we had some very solid diving today and when reviewing the footage felt we'd obtained some very promising leads. The whole team was pretty excited at the prospect of friday's diving.

Could u please wright more from tech, side ? Depth, gas etc ..

I hit 56m when searching the seabed but the wreck starts at 50m. The Tech-2 teams were using 18/45 twin 12's with an AL80 of 18/45 as a bottom stage with 50% and 100% for deco. The Tech-1 teams were using 18/45 with 50% for deco.

Bottom times were up to 40 mins for the Tech-2 and around 20mins for those who were Tech-1.

My longest dive had a 103 min runtime for 40mins on the bottom.

Hope that helps.
Cheers
Al

Also a couple of corrections to tasks for this dive

Team 2 - Andy, Rich
Head north east with goal of adding a series of lines running approximately east-west between the North line and the zig zag line

Team 3 - David, John Grogan
Survey North line, tieing in the zig zag line to the North line and the Capstan winch to the North-west line. Survey newly tie-ins.

Team 3 - Rob, Osama, Ricardo
Perform survey of the South east and south south east line triangle

Comments for the afternoon dive.
This was to be the first dive where we tried to obtain survey data. Due to the limited time available we decided that we would simply obtain distances and bearings to create a map of the lines (including key features where they were on the lines). When the lines were laid it was often not possible to determine where they started on the other lines which meant that Wednesday's sketch map contained a number of significant uncertainties or guesses as to where some of the newer lines had been laid. Those affecting the south-east / south south east lines had been resolved in the morning's dive, whilst those to the north were not discovered until Team 3 started the survey on the afternoon dive. The survey teams were able to complete the major objectives and although there was not enough time overnight to update the main map we were able to draw an updated line map sketch.

We elected to leave the tape measures behind and to rely on knot counting combined with estimating distances smaller than knot intervals. We realised after this dive that we ought to have gone for knots at 1m, rather than 5m, intervals due to the scale of the wreck. This is the sort of thing you only realise for the next time around having both seen the size of the wreck and tried to survey using the knots.
