Purpose
|
|
4th repeat swath bathymetry survey of SW section of Middle
|
|
Ground, and single beam depth sounding in a zig-zag pattern along
|
|
Middle Ground extending to the NE of the swath study area to get the
|
|
general geography of the bank outside the hi-res study area.

Summary
|
|
This was the 4th repeat swath bathymetry survey of SW section
|
|
of Middle Ground. We collected single beam depth sounding in a
|
|
zig-zag pattern along Middle Ground extending to the NE of the swath
|
|
study area to get the general geography of the bank outside the
|
|
hi-res study area.

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.

Got Help?
|
For 07035, we would appreciate any information on -- activity type, analog materials, contract, days at sea, dive count, kms of navigation, national plan, NGDC Info, owner, project, project number, publications, scanned materials, seismic description, station count, station description, submersible, tabulated info.
