Vsp Data

We have developed an anisotropic prestack depth migration code that can migrate either vertical seismic profile (VSP) or surface seismic data. We use this migration code in a new method for integrated VSP and surface seismic depth imaging. Instead of splicing the VSP image into the section derived from surface seismic data, we use the same migration algorithm and a single velocity model to migrate both data sets to a common output grid. We then scale and sum the two images to yield one integrated depth‐migrated section. After testing this method on synthetic surface seismic and VSP data, we applied it to field data from a 2D surface seismic line and a multioffset VSP from the Rocky Mountain Foothills of southern Alberta, Canada. Our results show that the resulting integrated image exhibits significant improvement over that obtained from (a) the migration of either data set alone or (b) the conventional splicing approach. The integrated image uses the broader frequency bandwidth of the VSP data to provide higher vertical resolution than the migration of the surface seismic data. The integrated image also shows enhanced structural detail, since no part of the surface seismic section is eliminated, and good event continuity through the use of a single migration–velocity model, obtained by an integrated interpretation of borehole and surface seismic data. This enhanced migrated image enabled us to perform a more robust interpretation with good well ties.

Two Populations

This paper reports results of a 2-year study of the caddisflies Oligophlebodes zelti (Limnephilidae) and Neothremma alicia (Uenoidae) in a first-order Rocky Mountain stream of southern Alberta. The Oligophlebodes population had a univoltine cycle: eggs were oviposited in July and August and hatched in about 20 days, and the larvae grew rapidly during the remainder of the ice-free season. Larvae overwintered in the fourth larval instar and molted to the fifth instar the following spring. Pupation occurred in June, and adults started emerging in mid-July. Annual production for the O. zelti population was 116 mg∙m−2∙year−1. The Neothremma population had a 2-year cycle. Eggs apparently hatched after freeze-up. Larvae overwintered in the second instar. Most of the population achieved the third instar by the following July and the fourth instar by August, and spent the second winter in either the fourth or fifth instar. There was about a 3-week prepupal stage the following July and then emergence in July and August. Annual production for the N. alicia population was 103 mg∙m−2∙year−1. Oligophlebodes zelti and N. alicia larvae fed mainly on fine particulate organic matter and diatoms. Both O. zelti and N. alicia larvae were found on rocks only in fast water areas, but the two populations did not inhabit the same riffles. The riffles inhabited by O. zelti were wider with lower slopes and water velocities than riffles dominated by N. alicia larvae. Correlation analysis, using several parameters, indicated that total periphyton of the rocks might be a major factor accounting for O. zelti's distribution. The microdistribution of the N. alicia population was not correlated with any food source.

Orthogonal Systems

Regional joints in southern Alberta form patterns that persist over an area extending from the Rocky Mountain Foothills to the Saskatchewan border. These patterns persist vertically through a section of rocks ranging in age from Late Cretaceous to Late Paleocene.The basic unit of jointing is an orthogonal system consisting of two sets of extension fractures. Two or more orthogonal systems may be present at a given locality creating a complex pattern of joints. System I predominates and has sets trending approximately 65 °and 155°, or roughly normal and parallel to the Rocky Mountains. System II joints trend approximately 5 °and 95°, but swing about 15 °clockwise in the Drumheller area. A system having sets trending 45 °and 135 °is present near Medicine Hat.System I joints roughly parallel intermediate width (32-64 km) subsurface structural undulations described by Robinson et al. (1969). System II joints trend parallel and normal to the crest of the Sweet-grass Arch. Further study is needed to determine the age and origin of jointing.Regional joints in southern Alberta show similarities with regional joints in similar structural settings on the Appalachian Plateau and on the Central Oklahoma Plains. Within these areas orthogonal systems of regional joints trend normal and parallel to the adjacent fold belt over vast areas and through great thicknesses of sedimentary rock.

Local Habitat

Fish and habitat were sampled from 110 reaches in the Salt River basin (Idaho and Wyoming) during 1996 and 1997 to assess patterns in fish assemblage structure across a Rocky Mountain watershed. We identified four distinct fish assemblages using cluster analysis: (1) allopatric cutthroat trout (Oncorhynchus clarki (Richardson, 1836)); (2) cutthroat trout – brook trout (Salvelinus fontinalis (Mitchell, 1814)) – Paiute sculpin (Cottus beldingi Eigenmann and Eigenmann, 1891); (3) cutthroat trout – brown trout (Salmo trutta L., 1758) – mottled sculpin (Cottus bairdi Girard, 1850); and (4) Cyprinidae–Catostomidae. The distribution of fish assemblages was explained by thermal characteristics, stream geomorphology, and local habitat features. Reaches with allopatric cutthroat trout and the cutthroat trout – brook trout – Paiute sculpin assemblage were located in high-elevation, high-gradient streams. The other two fish assemblages were generally located in low-elevation streams. Associations between habitat gradients, locations of reaches in the watershed, and occurrence of species were further examined using canonical correspondence analysis. The results suggest that stream geomorphology, thermal conditions, and local habitat characteristics influence fish assemblage structure across a Rocky Mountain watershed, and they provide information on the ecology of individual species that can guide conservation activities.
