Notes -
All times UTC 0835 UTC: Met Bill Danforth, Chuck Worley,
Barry Irwin at Harbor Bill & Chuck working in Ethernet interface to
swath mapping system as opposed to serial port. Talked to engineer
Matt in UK using Skype through The Unwired Village wireless
connection using laptop on fantail. picked up in harbor (Island
Queen point?). Cool! ~1400 Left Bill Danforth behind and headed out
toward Middle Ground. Overcast skies. 1-2 ft seas, light wind 5-10
knots from east. 1441 On station at beginning of zig-zag survey,
but GPS not receiving interally. Needed to reset on receiver. ~1600
Swath bathy system not removing pitch & roll, nothing seems to help,
so start doing zig-zag survey with single beam echosounder, hoping
that swath system will work by the time we reach the hi-res survey
area. 1700 Switched back to the old ISA Tem s, and that solved the
pitch & roll problem. The USB Tem s apparently has a timing problem.
Chuck asks: Could it be related to desktop computer not being
USB2.0? Line 27. Start mowing the the lawn from SE corner on Hypack
line 27. Started with swath of 30 m on a side, but then changed to
50 m on a side 100 m into the line or so, hoping to be able to skip
a few lines. Did not skip line 26, however, since we want to avoid
a hole at the beginning of line 27 when the width was only 30 on a
side. Skipped line 25. Line 24. Went back to 30 m on a side and
doing every line, because the lines go from shallow (6 m to 20 m).
Should really adjust the survey lines to try to follow contours of
the bank. 1809 Beginning line 18. heading 238 1904 begin line 11
1939 big rollers (during 30 seconds along line 7) 2019 Water is
noticably smoother rougher the south side of Middle Ground Barry
suggests running along
1 days at sea.
