Part B - Minimum Requirements on geological survey
7.2 Content
The geological report contains at least the following specifications:
• short project description,
• objective of the investigations,
• the company and persons involved,
• description of the investigations carried out
- period of time for work carried out in the sea and in the laboratory,
- description of all measuring systems and equipment used including specifications re
garding ranges of measurement and tolerance of individual parameters,
- relevant specifications from measuring protocols such as e. g. ambient conditions, sound
profiles in water, etc.,
- data processing,
• findings of the Desk Study,
• summary of the findings of individual investigations (e. g. bathymetry, echo-sounding meas
urements, seismic surveys, boreholes, probes). Summary of all relevant data (e.g. back-
scattering mosaic from side scan sonar investigations, seismograms) can be found in the
preliminary geological report,
• comparison of acoustic description of the sediment units with lithological description from
the stratification record (e.g. in a table) and cone penetration testing findings, geological
interpretation
• lists of anomalies discovered, and recommendations for further handling if necessary,
• locations of sections and boreholes, drilling logs in accordance with DIN 4023 including the
range of tolerance of each measurement system used, the positional accuracy of the sec
tions and exposures and the reference system used.
• presentation of findings in the form of geological longitudinal and cross sections of suitable
scale,
• assessment of the findings, illustration of the interpretation limits and remaining exploration
risks, and recommendations for further investigations if required,
• summary,
• digital data medium with digital map in CAD or GIS format, preferably as shape files and
• delivery of the processed seismic survey together with a freely available reader on digital
data media.
Unpublished results from neighbouring areas can only be accessed if these are published in
the report with the associated documentation.
