Out of the following, which records can produce highest resolution of the longer duration of paleoclimatic signatures during the Quaternary ?
Ice core
A good palaeoclimate archive for the Quaternary needs both a long, continuous record and a high (ideally annual) temporal resolution.
Polar ice cores satisfy both: snow accumulates as annual layers that can be counted, and cores such as EPICA Dome C span about 800 ka (several glacial–interglacial cycles). They preserve δ18O/δD (temperature), trapped air bubbles (CO2, CH4), dust and volcanic ash.
Marine cores span longer time but slow sedimentation and bioturbation smear the signal, so their resolution is typically centuries to millennia.
Speleothems give high resolution but are discontinuous and local, and tree rings, though annual, cover only the last ~10–12 ka of the Holocene.
Hence, the answer is Ice core.

A building is to be founded on a clay stratum. The water table is practically at ground surface level. Laboratory test show that the unit weight of the soil is r = 20 kN/m3 and classify the soil as a firm clay. The uniaxial compressive strength is qu = 150 kN/m2. Suppose that the footing will be square, 2 m wide, and the foundation depth will be 2 m below the ground surface, calculate the ultimate bearing capacity.
In a soil mechanics and engineering project, a stratigraphic column below the horizontal ground level of a wide valley is formed by 3 m of coarse gravels over a 12 m clay deposit. Below the clay is a highly permeable fractured sandstone. The water table in the gravel layer is 0.6 m below ground surface. In the sandstone substratum artesian condition with a piezometric height of 6 m above ground level exist. The gravel layer is very permeable and assumed to be hydrostatic. Determine the pore water pressure distribution.
