Recommend the most suited device to (i) collect a seabed surface sample, (ii) collect a sediment core, and (iii) conduct in-situ geotechnical testing of the seabed for the following conditions. Regarding (iii), comment on expected penetration depths. Sandy nearshore environments with significant currents and waves.
Estuary with mostly muddy to silty sediments, significant tidal currents, negligible wave action.
Deep ocean environments with water depth > 500 m.
There are no prior information available about the site.
Draw a conceptual sketch of a CPT including sensors and deployment mechanism. Describe step by step how to calculate undrained shear strength from CPT testing. Discuss pros and cons of CPT versus FFP testing.
