CoastWalk : a case study of environmental education in the communityPhillips, Jocelyn Katrina, n/a January 1995 (has links)
Walks organised at the community or 'grass roots' level both in Australia and
internationally have been organised as a means to highlight environmental and social
issues to the wider community.
This thesis focuses on a coastal walk from Melbourne to Sydney during November 1993
to March 1994 called CoastWalk which was organised as part of the Australian Conservation Foundation's 'Coasts in Crisis' campaign. The Walk aimed to highlight
environmental management problems specific to the coastal zone at both local and national
levels using mass media, information evenings and targeting groups within local
communities.
Using a case study approach to the methodology, combined with principles from both
social (interpretive) and empirical methods, this study involved determining the impact of
CoastWalk, i.e. whether it changed individuals at the levels of awareness, understanding
or action. The scope of the study does not include a detailed analysis of the communities
themselves, nor does it explore the psychological aspects of individual and social change.
It was found that the mass media aspect of the CoastWalk campaign created a short term
awareness of the need to have concern for coastal management issues in those who did
not participate in the Walk. For those who did participate, the impact was deeper and
profound, changing individuals understanding and actions towards coastal management
and translating into other areas of their lives. The impact of the Walk on local community
groups who supported the Walk was negligible and it was determined that CoastWalk did
not meet their needs.
Community involvement in environmental management or campaigning equates to long
term ownership and responsibility being taken for those issues. However, neither
community nor government intervention in environmental management alone can resolve
these issues successfully. This thesis argues that a combined approach from both
community and government organisations is required - but as exemplified by CoastWalk,
the success of this approach requires equality in communication and co-operation.
As other environmental awareness walks have occurred, it is evident that they are
perceived as worthy events by the community, and that there is potential for them to occur
again in the future. It is therefore essential for an evaluation to occur of the techniques
used to achieve their environmental education aims. Thus, the learning from previous
Walks can be built into future Walks enhancing their success.

Structure and kinematics of the permanent oceanic front off the Oregon coastCollins, Curtis Allan 07 April 1964 (has links)
Using the hydrographic data collected by the ACONA from June
1961 to May 1963, the Oregon coastal front has been examined. Representative
sigma-t surfaces were chosen to delineate the front, and
changes in position of these surfaces with time were used to obtain
zonal flow rates for the frontal and surface layers.
From May to early October upwelling resulted in offshore flow.
Onshore flow was indicated from late October to January, and indeterminate
zonal flow occurred during the remainder of the year. Flow
within the front agreed with these surface flows in ten of the fourteen
observational periods. / Graduation date: 1964

Climate and heat exchange in the oceanic region adjacent to OregonLane, Robert Kenneth 20 April 1965 (has links)
The climate and the exchange of heat between atmosphere and
ocean are examined in a region adjacent to Washington and Oregon,
and in two sub-regions adjacent to Oregon. The sub-regions are
chosen such that one contains the nearshore upwelling region and the
other borders it on the seaward side.
The data (ship weather observations, 1953 to 1962) reveal the
general seasonal variation of climatic factors in the regions studied
and the effects of the nearshore upwelling of cold water on the climate
over the coastal ocean region and the adjacent coastal land mass. In
the nearshore sub-region, summer values of temperature (air, wet
bulb, and sea surface) are lower than those to seaward, but winter
values are higher inshore than to seaward. The effects of these differences,
and of other factors, on the heat exchange processes are
examined with the use of empirical equations. It is seen that the processes
of evaporation and conduction are suppressed considerably
and net long wave radiation is slightly suppressed in the upwelling
region during the summer.
The effects of the reduction of heat loss to the atmosphere in
the summer upwelling region on the climate of coastal Oregon are
seen to be a slight reduction of air temperatures and, despite reduced
evaporation, a very slight increase of relative humidity.
Monthly means of daily net heat exchange between the sea and
the atmosphere are examined and correlated with the difference between
monthly means of the heat used per day in the oceanic evaporation
process and the monthly means of daily totals of heat estimated to be
used in the evaporation from a shallow pan under climatic conditions
identical to those accompanying the net heat exchange and oceanic
evaporation. / Graduation date: 1965

Continental shelf sediments, Columbia River to Cape Blanco, OregonRunge, Erwin John 01 December 1965 (has links)
Sediments on the inner portion of the Oregon continental shelf
consist of clean, well-sorted, detrital sand. This sand has an average
median diameter of 2.53Φ (. 173 mm) and is both positively and
negatively skewed. Deposits with median diameters in the coarse
sand and gravel classes occur at depths of 20 to 40 fathoms and
probably represent ancient beach or fluviatile deposits formed during
lower stands of sea level.
The outer shelf and upper slope are covered by poorly sorted
sediments with median diameters in the fine sand to fine silt classes.
Mean diameters of the sediments are almost always smaller than
their median diameters and the sediments are positively skewed.
The heavy mineral assemblages are dominated by the amphibole
and pyroxene groups and the opaque-garnet association.
Pyroxenes are most abundant in the coarser-grained sediments of the inner shelf and decrease in abundance offshore. Amphiboles are
most abundant in the finer-grained sediments of the outer shelf and
upper slope. Highest concentrations of the opaque-garnet association
also are found in the inshore samples.
Sediments of the continental shelf are derived from two principal
sources, rivers and erosion of coastal terrace deposits.
Rivers are probably contributing only fine-grained material to the
shelf as much of the coarser fluviatile material is thought to be
trapped in the estuaries. The terrace deposits are actively being
eroded and are thought to contribute about 21,000,000 cubic feet
(.00013 cubic miles) of sediment to the continental shelf annually.
Evidence suggests that much of the inner-shelf sand is probably
a relict transgressive sheet sand that was deposited during the
last rise in sea level. Most of the deposition of the modern sand on
the shelf has been confined to the inner portion of the inner shelf.
Finer-grained sediments have been deposited on the outer shelf and
upper slope.
Characteristics of the sediments on the present continental
shelves may be useful in identifying continental shelf deposits in
the geologic column. / Graduation date: 1966
