The Black Bay Shear Zone, northwestern Saskatchewan, lies within the Rae Province of the Canadian Shield. It is one of several major, northeast trending, steeply dipping shear zones that were active during the Paleoproterozoic Trans-­Hudson or Thelon Orogenies. For part of its exposed length of approximately 50 km it separates Archean supracrustal gneisses of the Tazin Group to the northwest, from the unconformably overlying Paleoproterozoic, red-bed sequence of the Martin Group to the southeast. Deformation fabrics along the Black Bay Shear Zone indicate the sequential development of early ductile to late brittle episodes of movement. The early ductile episode (D_{<font size=1>1</font>}, pre-Martin Gp) is characterized by a 1 km-wide mylonite belt in the Tazin gneisses, with mylonitic lamination (C-fabric), dextral ä-asymmetric winged porphyroclasts, stretch lineation (L<ub><font size=1>1</font></sub>) and rare sheath folds. This was followed by a ductile to brittle transition (D_{<font size=1>2</font>}, also pre-Martin Gp) characterized by small asymmetric folds in C, and small post-C compressional and extensional shear bands (SB) ranging from thin ductile shear zones to brittle fractures commonly vein filled. The late brittle phase (D_{<font size=1>3</font>}, post-Martin Gp), to which uranium vein mineralization is related, included the formation of a major brittle fault zone along the southeastern side of the mylonitic shear zone, and several sets of vein filled joints. Movement directions during D_{<font size=1>1</font>} to D_{<font size=1>3</font>} are reflected by various shear sense indicators. The D_{<font size=1>1</font>} dextral ä-asymmetrical winged porphyroclasts, combined with the gently NE and SW plunging L_{<font size=1>1</font>}, stretch lineation, indicate sub-horizontal dextral displacement during the ductile phase of deformation. Predominantly NE-verging and steeply dipping SW plunging minor D_{<font size=1>2</font>} folds, along with the predominantly dextral-verging, post-C shear bands, indicate that oblique dextral SE-side-up slip occurred during the ductile to brittle transition. Brittle movement (D_{<font size=1>3</font>})resulted in the preservation of an approximately 8-km thick succession of Martin Group on the SE-side of the fault, indicating a SE-side-down vertical throw of at least 8 km. The local presence of poorly preserved, down-dip slickenlineations suggests that at least some of this movement was dip slip. Time constraints on deformation are poor, tentatively all of the Black Bay Structure deformational history took place between 2300 Ma and 1700 Ma.

Ta-pong Bay is a shallow coastal lagoon located at the southwestern Taiwan, with only one inlet permanently connecting to the sea. The water exchange, flowing out or into the Bay, is chiefly driven by tidal force. Many kinds of nutrition are gradually accumulated in the Bay, leading to the situation of eutrophication to be more serious. This research utilizes the POM numerical model (Princeton Ocean Model) to simulate the circulation of Ta-pong Bay and long-term water mass transportation. Further, we had used a towed ADCP to survey the flow fields of the Bay and set up a fixed ADCP to measured local velocity for 15 days, for helping us more to understand the flow field. This study using high-resolution 3-D numerical model had been developed with 50m by 50m horizontal resolutions to calculate the problem of water exchange of the lagoon. The model is driven by tidal force, northerly and southerly wind stress. The model results show that the tide-generated force is quite revealed at the tidal inlet where the biggest velocity can researches to 1 m/s during ebb tide, 0.5 m/s during flood tide. The low-frequency motion of the bay is mainly driven by wind stress. The residual current is about 0.03 m/s during blowing northerly wind and about 0.05 m/s during blowing southerly wind. Generally speaking, the average residence time in the south of the lagoon is over 30 days and in the central bay is about 7~12 days and in the north of the lagoon near the tidal mouth is about 1~2 days.

The small-scale vertical migration patterns and spatiotemporal variations of copepods in the Tapong Bay, southwestern Taiwan, from 2003 to 2005 were studied. The differences in species composition and abundance of copepods before and after the removal of oyster culture racks in relation to tides, hydrography and other environmental factors were also compared and herein discussed. Tapong Bay has distinct dry (October to April) and wet (June to August) seasons and exhibits apparent inter-annual variation, cold, saline and low Chl a concentration in dry season, and vice versa in wet season. Most copepod species displayed normal diel vertical migration, descending to the deeper water during daytime and ascending to near surface water at night. Copepods were always more abundant at night than during daytime. Higher abundance but smaller species number of copepods were found during ebb than flood tides. In all, 123 copepod species belonging to 18 families and 31 genera were identified. Oithona oculata, Parvocalanus crassirostris, Acartia sinjiensis, Acartia sp., Bestiolina amoyensis and copepod nauplius were predominant and together they composed 74% of the total number of copepods. These dominant species showed apparent seasonal changes, with higher abundance in autumn and winter. Copepod assemblage also showed apparent difference between stations. Warm-saline-coastal species dominated in the outer region, while small-size taxa and common species of estuaries and aquaculture ponds dominated in the inner bay. Results of indicator species analysis could possibly recognize the area affected by tides and water masses, and identified Acrocalanus gracilis to be the indicator species of flood tide and outer region of the bay, and Acartia sinjiensis the indicator species of ebb tide and inner bay. Our results showed that after the removal of oyster culture racks the species number and abundance of copepods were higher but the seasonal and spatial differences in abundance became smaller. Furthermore, the increase in abundance of zooplankton and copepods in the Bay after the removal of oyster culture racks might be due to the absence of oyster population which exerts great filter¡Vfeeding impact on phytoplankton, and decrease of predation pressure from moon-jelly that usually aggregated in the inner Bay and settled down their polyps on the oyster racks but disappeared after the removal.

This study defines depositional environments and constructs the sequence stratigraphic framework of the lower Miocene Oakville Formation and the basal part of the middle Miocene Lagarto Formation in the Carancahua Bay area. The Early Miocene of the northwestern Gulf of Mexico represents a tectonically stable period with a high sediment influx. The analysis is based on a data set composed of 45 well logs and 200 mile2 area 3D seismic volume. The study interval was divided into five depositional sequences 1-5 that encompass 0.6-2.5 My. LST, TST, and HST systems tracts were recognized by stacking patterns and bounding surfaces. Sequence thickness increases from sequence 1 to 3 and displays reverse thickness trends from sequence 3 to 5, implying changes in accommodation space relative to sediment supply, beginning with high rates of accommodation and evolving into low accommodation rates relative. Besides type-1 depositional sequence which forms during relative sea-level fall below the shoreline break, regressive units of T-R sequence model were also defined and delineated. The interval contains four regressive units, R-Unit1-4. The R-Unit net sandstone maps exhibit the same characteristic of a dip-oriented source of delta-plain origin and a delta-front depocenter basinward. Integration of well log patterns, sandstone dispersal trends from net sandstone maps and seismic stratal slices led to interpretation of depositional environments in each sequence. LST deposits are represented mainly by incised-valley fill facies. TSTs are composed predominantly of retrogradational barrier/tidal-inlet facies, whereas other TSTs contain lagoonal and reworked deltaic systems. HST1 is composed mainly of fluvial-dominated deltaic systems, whereas deltaic systems in other HSTs exhibit wave-influenced deltaic and strandplain depositional systems. The integrated methodology reveals depositional facies variations in contrast to previous work that interpreted these deposits as shorezone systems. During LSTs coarse-grained sediments bypassed shelf through incised valley systems to a downdip depocenter. More sandy sediments were stored on shelf as deltaic and strandplain deposits during HSTs. In contrast to the others, destructive process occurred in TSTs and reworked sandy sediments, for example from delta fronts to barrier bar and lagoonal facies. Submarine fans form by sediments transported through incised-valley systems and delta fronts are commonly good reservoirs. Hence, presence of such depositional facies in the study area might be genetically linked to exploration targets. / text

Boundary Bay is a novel that explores important areas of investigation linked to education. These fields of inquiry include: literary study and the teaching of literature, aesthetics and artistic production. The novel also investigates the nature of teachers' lives in school and university settings, the nature of institutional education, societal issues affecting intellectual and creative life, the roles of the woman poet and teacher, the social structures and conventions of marriage and contemporary women, the conflicts and paradoxes of motherhood, the issues of teen suicide and homosexuality, and the transformative power of literature and artistic forms of seeing the world. As an example of arts-based qualitative research, the "art of fiction" is envisioned as an extension of human experience. The novel or literary narrative as a viable mode of representation for research is envisioned in light of the perception that ideas can be reflectively addressed through the arts in order to enlarge human understandings. Boundary Bay explores the vital roles literary fictions play in our everyday lives and in educational processes. Fictions are not the unreal side of reality or the opposite of reality: they are conditions that enable the production of possible worlds. In this sense, fiction can become a premise for epistemological positionings. The writing of Boundary Bay is informed by narratives of beginning secondary school teachers as well as the narratives of Ph.D. candidates and university educators. Boundary Bay is a novel that forms a response to the debate at the 1996 Annual American Educational Researcher's Association Meeting (AERA) between Elliot Eisner and Howard Gardner recorded in "Should a Novel Count as a Dissertation in Education?" (Saks, 1996; Donmoyer, 1996). The debate between Eisner and Gardner continued as Boundary Bay was presented at a symposium titled "Shaking the Ivory Tower: Writing, Advising and Critiquing the Postmodern Dissertation" at AERA 1999 in Montreal. The manuscript of poetry interwoven through Boundary Bay was short-listed for the 1998 CBC Canada Council Literary Awards. Boundary Bay was a semifinalist for the 1999 Robertson Davies Prize for fiction.
