Deep boundary current disintegration in Drake Passage
No full textThe fate of a deep boundary current that originates in the Southeast Pacific and flows southward along the continental slope of South America is elucidated. The current transports poorly ventilated water of low salinity (a type of Pacific Deep Water; PDW), into Drake Passage. East of Drake Passage, the boundary current breaks into fresh anticyclonic eddies, nine examples of which were observed in mooring data from December 2009 to March 2012. The observed eddies appear to originate mainly from a topographic separation point close to 60°W, have typical diameters of 20–60 km and accompanying Rossby numbers of 0.1–0.3. These features are likely to be responsible for transporting PDW meridionally across the ACC, explaining the near-homogenization of Circumpolar Deep Water properties downstream of Drake Passage. This mechanism of boundary current breakdown may constitute an important process in the Southern Ocean overturning circulation

Drake Passage summary report: Cruises on RRS "James Clark Ross", 1993-2000. Drake Passage repeat hydrography: WOCE Southern Repeat Section 1b - Elephant Island to Burdwood Bank.
No full textThis report documents five early cruises in the Drake Passage annual repeat series conducted by Southampton Oceanography Centre in collaboration with the British Antarctic Survey. The series began under the auspices of the World Ocean Circulation Experiment as southern repeat section SR1b with a SeaSoar (towed undulating profiler) occupation in 1992. We document cruises from 1993 (JR0a), 1994 (JR0b), 1996 (JR16), 1997 (JR27) and 2000 (JR47). The cruises were all hydrographic CTD sections across Drake Passage between Burdwood Bank and Elephant Island, comprising 30 stations. One cruise (JR27) was occupied at higher resolution with 52 stations; also additional chemical measurements were made. On two cruises (JR16 and JR27), a lowered acoustic Doppler current profiler (ADCP) was introduced to provide full-depth water velocity profiles. Other measurements (vessel-mounted ADCP, sample salinity, navigation, expendable athythermographs, etc.) are described in context

The Distribution and Reproduction of the Plains Spadefoot Toad, "Scaphiopus Bombifrons", in Iowa
No full text49 leaves. Advisor: James L. ChristiansenThe problem. The northeastern extreme of the range of "Scaphiopus bombifrons" occurs in Iowa. This study was designed to determine whether the species should continue to be classified as threatened with extinction in Iowa. At the
onset of this study, the species had been found only in a few localities in the loess hills. The study attempted to determine whether or not the species occurred beyond the dry loess soil and adjacent flood plain. Little has been published
concerning the reproduction of the plains spadefoot toad. This study attempted to determine time of breeding, number of eggs produced, and the possible relationship among fat, breeding, and above-ground activity.
Procedure. The range was determined by searching for specimens throughout the loess hills on roads during rain or on warm, humid nights. Body length, testes, ovaries and fat bodies were measured to determine size at sexual maturity, cycle of activity and breeding, and gonadal and fat body cycles.
Findings. "S. bombifrons" was found to occur throughout the loess hills, and no longer merits threatened status. It was not found beyond the deep loess soil. Adult females were more abundant than males, were larger, and attained maturity
at a more consistent size. Most individuals were not active below 60°F air temperature, and breeding probably occurred once in a season, usually in June. Mature females produce an
average of about 2600 egqs each year. As many as two years were needed for juveniles to attain sexual maturity. Gonads were largest in June, although reproductive capability could apparently be attained through much of spring and summer.
Aestivation and hibernation appeared to consume more fat than did the production of gametes.
Conclusions. "S. bombifrons" is a moderately abundant, possibly recent invader of the loess hills. It appears limited to loess habitats. The species produces a large number of egqs in Iowa, which may help to account for the abundance it seems to have achieved over a period of less
than 40 years.
Recommendations. A study of a marked, breeding population should be conducted. It will answer questions concerning life span of individuals, survival over winter, number of breedinq periods per year, growth, and could enable estimation
of local populations
Control of Mode and Intermediate Water Mass Properties in Drake Passage by the Amundsen Sea Low
No full textThe evolution of the physical properties of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW) in the Drake Passage region is examined on time scales down to intraseasonal, within the 1969–2009 period. Both SAMW and AAIW experience substantial interannual to interdecadal variability, significantly linked to the action of the Amundsen Sea low (ASL) in their formation areas. Observations suggest that the interdecadal freshening tendency evident in SAMW over the past three decades has recently abated, while AAIW has warmed significantly since the early 2000s. The two water masses have also experienced a substantial lightening since the start of the record. Examination of the mechanisms underpinning water mass property variability shows that SAMW characteristics are controlled predominantly by a combination of air–sea turbulent heat fluxes, cross-frontal Ekman transport of Antarctic surface waters, and the evaporation–precipitation balance in the Subantarctic zone of the southeast Pacific and Drake Passage, while AAIW properties reflect air–sea turbulent heat fluxes and sea ice formation in the Bellingshausen Sea. The recent interdecadal evolution of the ASL is consistent with both the dominance of the processes described here and the response of SAMW and AAIW on that time scale

A Phenomenological Study on The Lived Experience of First and Second Year Teachers in Standards-Based Grading Districts
No full text228 leavesABSTRACT
Problem: There is an existing cycle of questionable grading practices at the K-12 level. As a
result, districts continue to search for innovative methods of evaluating and reporting student
progress. One result of this effort has been the adoption of a standards-based grading approach.
Research concerning standards-based grading implementation has resulted in an abundance of
strategies to change existing practices used by educators. Very little attention has been given to
the experience of new educators, who are still developing their educational pedagogy and
practice for the first time.
Procedures: This hermeneutic phenomenology (Heidegger, 2008; Van der Zalm & Bergum,
2000) explored the lived experience of 11 first or second year teachers in districts currently
utilizing a standards-based grading approach. The research question for this study was: What is
the lived experience of first or second year K-12 educators in districts using standards-based
grading policies? This overarching research question was supported by five supporting subquestions,
which utilized Senge’s (2006) Five Disciplines of the Learning Organization as a
conceptual framework. Purposeful, criterion, and stratified purposive sampling were all used for
recruiting participants for this study (Creswell, 2014; Salmons, 2010; Van der Zalm & Bergum,
2000). Data was collected using a three-interview approach recommended by Seidman (2013),
including life history, details of experience, and reflection on the meaning. Additional data
gathered included supplemental materials and researcher reflections. The data analysis process
included coding, triangulation, member-checking, and inter-coder agreement.
Findings: Findings were communicated in a descriptive and interpretive method, in order to gain
understanding of a specific phenomenon (Heidegger, 2008; Van der Zalm & Bergum, 2000).
Data analysis resulted in the following findings: (a) inconsistencies with grading and assessment
preservice training, (b) student teaching experiences, (c) professional development practice
concerning grading and assessment, (d) focusing on connections with students, (e) navigating the
traditional K-12 assessment model, (f) experiences of new teachers as K-12 students, (g) grading
based on standards, (h) inconsistencies in SBG implementation, (i) balancing theory and
practice, (j) the role of mentors, (k) the function of PLCs, (l) the role of new educators on teacher
teams, (m) the responsibility of teachers to grade student work, (n) holding students accountable
for their work, and (o) translating a number to a letter grade.
Conclusions: Varying experiences in preservice programs, the presence of a mentor, a lack of
consistent SBG implementation, and fundamental misunderstandings of the standards-based
grading system create a unique lived experience for the new educators.
Recommendations: Preservice programs should be providing more specific training for new
educators in the areas of assessment and grading. Preservice educators would benefit from more
explicit instruction concerning assessment and grading; specifically, preservice programs should
explore implementing a specific assessment and grading course. Districts that are currently
utilizing a standards-based model should ensure consistent implementation of SBG building and
district-wide, as well as adopt a competency-based professional development model for their
teachers concerning grading and assessment practice. It is essential for districts to consistently
and accurately communicate the rationale for SBG to their respective faculties
RRS James Cook Cruise JC031, 03 Feb-03 Mar 2009. Hydrographic sections of Drake Passage
No full textRepeat hydrographic sections (WOCE sections SR1 AND SR1b) were occupied in Drake Passage during February - March 2009 aboard the RRS James Cook (JC031). The primary objective of this cruise was to measure ocean physical, chemical and biological parameters in order to establish regional budgets of heat, freshwater and carbon. A total of 84 CTD/LADCP stations were sampled across Drake Passage. In addition to temperature, salinity and oxygen profiles from the sensors on the CTD package, water samples from a 24-bottle rosette were analysed for salinity, dissolved oxygen and inorganic nutrients at each station. Water samples were collected from strategically selected stations and analysed onboard ship for SF6, CFC’s, pCO2, TIC, alkalinity, and phytoplankton. Some bottle and underway samples were analysed for Ar/O ratios. In addition, salinity samples were collected and analysed from the ships’ underway system to calibrate and complement the data continually collected by the TSG (thermosalinograph). Full depth velocity measurements were made at every station by an LADCP (lowered acoustic Doppler current profiler) mounted on the frame of the rosette. Throughout the cruise, velocity data in the upper few hundred metres of the water column were collected by the ships’ VMADCP (vessel mounted acoustic doppler current profiler) mounted on the hull. Meteorological variables were monitored using the onboard surface water and meteorological sampling system (SURFMET). This report describes the methods used to acquire and process the data on board the ship during cruise JC031
