Data of field activity F-1-84-HB in Humboldt Bay, Northern
California from 04/02/1984 to 04/04/1984
- Abstract:
-
Chief Scientist: John Dingler. Data (bathymetry, meters,
navigation) of field activity F-1-84-HB in Humboldt Bay,
Northern California from 04/02/1984 to 04/04/1984,
<http://walrus.wr.usgs.gov/infobank/f/f184hb/html/f-1-84-hb.meta.html>.
- Supplemental_Information:
-
Equipment Used -
bathymetry data directory exists
meters data directory exists
navigation data directory exists
Similar information is available for thousands
of other USGS/CMG-related Activities.
If known, available are Activity-specific
navigation, gravity, magnetics, bathymetry,
seismic, and sampling data; track maps; and
equipment information; as well as summary
overviews, crew lists, and information
about analog materials.
If available, access to physical samples is
described in the "WR CMG Sample Distribution
Policy" at:
<http://walrus.wr.usgs.gov/infobank/programs/html/main/sample-dist-policy.html>

Navigation Data
Converted to time format with year at start.
05/21/85 KAYE USR$DISK:[KAYE.F1]NEW.650;
USR$DISK:[DRS.REFMT]REFORMAT.EXE;4
Del Norte data from the Fast Eddy. This file was combined from 4
files which had been divided by julian day. Data was not collected
continuously for 24 hours so some time gaps will occur. Time is in
local mean time (LMT).
