Survey coverage:
|
•Primary line: KNR 179-1, Line 7, SP 204 0615
•Crossing line: KNR 179-1, Line 12, SP 206 0455

|
Objective:
|
Lower end of depth transect; lower to upper Eocene and possible Eocene/Oligocene boundary (the entire section of Eocene strata is ~500 m thick at this site, allowing potential deeper penetration than currently proposed); early Eocene warm period; Eocene hyperthermals; middle and late Eocene impacts; transition to icehouse climate; Eocene CCD; chemistry of Eocene deep water. Just above the Eocene CCD.
