Portions of Yellowstone Lake sit on top of a vigorous but not well understood hydrothermal system situated in a region of intense geologic and environmental forcings. A heat flow study conducted over the Stevenson Island Vent Field (SIVF), a vent field at the bottom of Yellowstone Lake underlain by an...
Heat flow analysis of the Costa Rica convergent margin is carried out for seven core sites drilled during Integrated Ocean Drilling Program (IODP) Expeditions 334 and 344 as part of the Costa Rica Seismogenesis Project (CRISP). These expeditions were designed to develop a better understanding of erosional subduction zones. Heat...
Measuring surface heat flow at the Hikurangi Trough is key toward characterizing the local thermal regime and the influence of thermally sensitive processes such as fluid flow and slow slip. Marine heat flow data were collected during May– June 2015 in the northern Hikurangi Trough at sites seaward and landward...
An integral component to understanding lithospheric rheology, fault mechanics, and geodynamic processes is knowledge of the subsurface thermal regime. This study presents thermal data from 26 new borehole sites drilled during the installation of borehole strain meters as part of the Plate Boundary Observatory (PBO). These data extends existing coverage...
Flower bud influence on rootability of Rhododendron shoots was
assayed by rooting leaf-petiole cuttings. Monthly samples of an easy-and
an intermediate-to-root cultivar showed periods of poor rooting
in the latter during flower development, although both rooted similarly
during bud dormancy. The decrease in rooting-potential following
flower initiation and development was...
The development of Easter lily Lilium longiflorum Thunb.
'Ace' bulblets from scales was used to study the influence of scale
pre-cooling, growing temp, and daylength on scale initiation,
scale "filling" (bulbing), and scale leaf formation. The development
of 'Croft', 'Ace', and 'Nellie White' daughter bulbs in field-grown
yearlings was also...
Greenhouse-grown, September-harvested Lilium longiflorum cv. 'Nellie white' bulbs were used to determine temperature requirements during 5 pre-bloom and 1 post-bloom phases of development each of 1 month's duration. Plantes were subjected to 3 air temperatures(24°day/ 18°C night, 18°/13° and 13°/10°) in combination with soil temperatures at 30°, 24°, and equal...
Experiments were conducted to determine if the plagiotropic
growth habit of rooted cuttings of Douglas-fir might result from a
system favoring the accumulation of indoleacetic acid in the adaxial
side of the shoot in response to vertical placement.
Actively growing excised branch terminals were subjected to
gravitational disorientation to determine...
The relation of bud and cambial activity to root initiation and
elongation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)
stem cuttings was studied through two successive growth cycles.
Stem cuttings of current season's growth were taken periodically
from field-grown Douglas-fir trees to determine: (1) origin and
development of root initials; and...
