Chief Scientist: Bruce Richmond. Geodetic data (geodetic, navigation) of field activity W-11-97-OA in Waimanalo Beach, Alo'ilo'i RoadOahu, Hawaii from 03/13/1997 to 03/13/1997, http://walrus.wr.usgs.gov/infobank/w/w1197oa/html/w-11-97-oa.meta.html. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public. Equipment Used - geodetic data directory exists navigation data directory exists Notes - Other field activities at Waimanalo Beach, Alo'ilo'i Road on Oahu also have Activity IDs beginning with "W-1" 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.
