Abstract:

University of Hawaii,United States Geological Survey, Menlo Park, California. Chief Scientist: Bruce Richmond. Geodetic data (geodetic, navigation) of field activity L-81-94-OA in Central Lanikai (3)Oahu, Hawaii from 08/04/1994 to 08/04/1994, <http://walrus.wr.usgs.gov/infobank/l/l8194oa/html/l-81-94-oa.meta.html>.

Purpose:

These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Supplemental_Information:

Equipment Used -
geodetic data directory exists
navigation data directory exists
Notes -
Other field activities at Central Lanikai (3)
on Oahu also have Activity IDs beginning with "L-8" and ending with "-OA"
<P>
Cross-shore beach profile data were collected as a component of
the Hawaii Coastal Erosion Study, a cooperative effort by U.S.
Geological Survey and University of Hawaii in order to document
seasonal and longer-term variations in beach volume and behavior.
The overall objectives of the Hawaii Coastal Erosion Study are to
document the recent history of shoreline change in Hawaii and to
determine the primary factor(s) responsible for coastal erosion
in low-latitude environments for the purpose of predicting future
changes and to provide quality scientific data that is useful to
other scientists, planners, engineers, and coastal managers.
<P>
The overall strategy consists of first quantifying the magnitude
and location of serious erosion problems followed by close monitoring
of coastal change in critical areas. Bi-annual beach profiles have
been collected at over 40 critical beach sites on the islands of Oahu
and Maui. Once sufficient background information is analyzed and key
problems are defined, field sites will be selected for detailed process-
oriented studies (both physical and biological) to gain an understanding
of the complex relationships between reef carbonate production, sediment
dispersal, and the interaction of man-made structures with sediment
movement along the shore.
<P>
Information derived from this project will be used to develop general
guidelines for sediment production, transport, and deposition of low-
latitude coasts. Planned major products include a comprehensive atlas of
coastal hazards, journal articles and reports presenting results of our
studies, and a &quot;living&quot; database of shoreline history and changes based
on results of the beach profile monitoring and softcopy photogrammetric
analysis.
<P>


Cross shore beach profiles were measured using a Geodimeter
464 total station and swimming rodman. The total station was
set up at a non-specific position on the beach. Up to five
permanent reference points were first surveyed in order to
establish the position of the station relative to the established
profile line. Beach profile measurements were then taken from
a point landward of the active beach to as far offshore as
conditions would allow (typically -4m water depth). Specific
morphologic features (high water, berm crest, top of beach toe,
etc.) were noted. Data were post-processed as follows Survey data
were downloaded from the Total Station memory, automatically
creating a RAW file and an associated JOB file. The RAW file
was used to generate a PTS file (UTM field coordinates are
extracted from the RAW file) Note: no recalculation is performed
on the original file). PFCODE.EXE was used on the JOB file to
generate an ED file. The ED file was edited to include necessary
Program 10 information, Points block listing, and INFO codes.
Field procedures were checked and corrected as necessary.
PFGD.EXE was used on the ED file to generate a PF file (Cartesian-
based, relative XYZ coordinates). Extraneous lines were removed
from the PF file to generate a DAT file (relative XYZ coordinates) DAT
files were compiled into a SUMMARY file (Excel) format, plotted,
and where necessary, corrected relative to a primary reference point.
Where GPS positions of the reference points were available, the entire
summary file was re-referenced to an absolute vertical elevation
(meters above the Local Hawaii Tidal datum).

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>
Primary access to the USGS/CMG Information Bank's digital data, analog data, and metadata is provided through... <http://walrus.wr.usgs.gov/infobank/>
