Site BSB-5B

Priority: Primary
Position: 55°43.290′N, 15°13.590′E
Water depth (m): 61
Target drilling depth (mbsf): 36
Approved maximum penetration (mbsf): 42
Seismic coverage: Primary line(s): GeoB06-057, SP 18700, SES-96 parametric sediment echosounder
Imagery: No photography or video available.
Sampling: No marine drilling, but land drilling (Lykke-Andersen et al., 1993), Core 318270-3 (vibro core), Core 318280-5 (vibro core) (FS Merian Cruise MSM-01).
Objectives (see text for details): To drill and recover early and mid-Weichselian littoral lake sediments.
Drilling Program: Up to 3 × APC to refusal, XCB to target depth and up to 5 short cores to capture the upper 0.75 m of the sequence undisturbed.
Downhole logging program: Standard logging suite: neutron-porosity, lithodensity, gamma ray, resistivity, acoustic, and formation image.
Anticipated lithology: Holocene mud, glacial varved clays, glacial tills, and Eemian mud.
