- As site geologist at DVDP hole 3, P. Kyle was responsible with Dr. S.B. Treves (the Project Scientist) for logging and examining the core. DVDP 3 reached 381 m in depth and recovered 341.16 m of core. The rocks penetrated consisted of ten lava flow units and five pyroclastic units. The oldest unit, 214 m thick, is believed to be a hyaloclastite. The units were assigned to four rock types, which are from youngest to oldest: hawaiite, augite-kaersutite basalt, olivine-augite basalt and hyaloclastite. Detailed descriptions of the core and thin sections similar to that prepared for DVDP 1 and 2 (Treves and Kyle, 1973a) have been written up (Kyle and Treves, in press).
- Mt. Erebus was observed to be in a continuing state of activity similar to that reported last year (Giggenbach et al, 1973; Treves and Kyle, 1973b). Lava was observed flowing from a small vent into a partially frozen lava lake. Gas explosions in the crater were of a similar frequency but longer (6 - 25 seconds) in duration than those previously reported (Giggenbach et al, 1973).
