Bioerosion on shore platforms developed in the Waitemata Formation, Auckland
No full textBioerosion - the removal of lithic substrate by the erosive activities of living organisms- has not previously been discussed for New Zealand shore platforms. This paper aims at drawing attention to bioerosion as a process active in shore platform development. Detailed reference is made to bioerosion occurring on the alternating sandstones and siltstones of the Waitemata Formation found outcropping on the coastline around Auckland. In this area several facets of shore platform morphology may be attributed to the direct effects of boring and browsing marine organisms. A classification of animals causing bioerosion, based on mechanism of erosion, is presented, and the geomorphic significance of the various groups discussed
The role of mass-movement in shore platform development along the Gisborne coastline, New Zealand
No full textTidal shore platforms form a conspicuous part of the coastal scenery north of Gisborne, New Zealand. Some of these platforms are being extended landward under present-day conditions. Present widening results primarily from cliff-retreat by mass-movement. The coincidence in distribution of areas of wave convergence, mass-movement and shore platforms suggests a genetic connection between these marine and subaerial process and response elements. Various types of mass-movement are involved in cliff-retreat, notably slumps, flows, debris slides and soil and rock falls. While the products of such mass-movement forms are removed by wave action, extensive boulder fields on some shore platforms indicate that removal is not always complete. Not all of the shore platforms on this coast are being widened at present. Widening has ceased where active mass-movement is not occurring
Shore platforms and mass movement: a note
No full textShore platforms and mass movement phenomena are important elements in the coastal scenery of the British Isles. Both features are particularly well developed along the English Channel coast. Where mass movement is of major importance it tends to inhibit the exposure of shore platforms. Under certain conditions it may temporarily protect the platform from further erosion. The factors which encourage the formation of shore platform and mass movement differ. Mass movement appears to be a secondary process, and does not seem to participate directly in either the primary formation of the shore platform or in its subsequent evolution
Shore platforms and mass-movement: A reply
No full textImplicit in Mr Wright's note on shore platforms and mass-movement is a criticism of our findings on the role of mass-movement in shore platform development along the Gisborne coastline, New Zealand (McLean and Davidson, 1968). The lack of explicit criticism makes any reply difficult; we are not rebuked on our own evidence, nor is any fresh evidence presented from the same area to make it necessary for us to change or modify our original views

Rocky shore biotic assemblages of the Maltese Islands (Central Mediterranean) : a conservation perspective
No full textLimestone rocky shores constitute ca 90.5% of the 272km coastline of the Maltese islands. Only some 40% of this rocky coastline is gently sloping and easily accessible. Such shores are heavily impacted with 96% of the accessible coastline dominated by tourist-related or by maritime activities. We characterized the biotic assemblages of lowland Maltese rocky shores and tested the popularly held view that given the scarce variation in physical characteristics, such shores form a homogenous habitat. Belt transects were laid perpendicular to the shoreline from biological zero to the adlittoral zone on seven Coralline Limestone and one Globigerina Limestone shores. Cover (for algae and encrusting species) or population density (for animals except sponges) were estimated using 0.5m X 0.05m quadrats placed contiguously for the first few metres and then at regularly spaced intervals. Overall, 19 faunal and 47 floral species, and 10 faunal and 8 floral species were recorded from the Coralline and Globigerina transects respectively, with 60.8% faunal and 25.6% floral species common to the two substrata. Hierarchical clustering showed that the Coralline and Globigerina transects harboured distinct biotic assemblages and identified an upper shore assemblage dominated by the littorinid Melarhaphe neritoides and barnacles, and a lower shore assemblage dominated by algae and molluscs; a mid-shore transition zone where certain species from both assemblages reached peaks of abundance was present in almost all Coralline and the majority of Globigerina transects. Differences in biota between the two types of shore are most likely primarily related to differences in microtopography and, to a lesser degree, to exposure. It is concluded that in spite of gross physical similarity, Maltese lowland rocky shores are biotically inhomogeneous, making conservation of individual sites much more important than previously thought.peer-reviewe
Marshall Shore interview, tape 2
No full textMarshall Shore was born in Farmington, Washington in 1916 and graduated from Lincoln High School in Seattle 1934. He was enrolled at the University of Washington when he was drafted into the Army in 1940, serving as a B-17 navigator in Europe during World War II. After World War II, Shore continued to serve in the Air Force performing work with intercontinental ballistic missile installations and other bases both in the United States and abroad. Shore retired in 1972. In retirement, Shore managed farms in the Columbia Basin and worked on histories of Farmington, as well his personal and family histories.

Impacts of Hurricanes Frances and Jeanne on Two Nourished Beaches along the Southeast Florida Coast
No full textSite inspections and beacli profile surveys of nourislied beaclies in the city of Boca Raton, and Town of Palm Beach, Florida show that the nourished beaches protected the shore from hurricane impacts in 2004. Striking the southeast coast of Florida within 20 days of each other. Hurricane Frances (Sept. 5, 2004) and Hurricane Jeanne (Sept. 25, 2004) had hurricane-force winds extending more than 120 miles from the center. The eye of Frances made landfall as a Category 2 storm and Jeanne made landfall as a Category 3 storm on the Saffir-Simpson Hurricane Intensity Scale, Above-average waves and surge affected the entire Florida east coast. Although these beaches were on the return or weak side (southwest quadrant with winds from the southwest as the eye traversed the shore) of both hurricanes, hurricane-uiduced waves affected the coast at least three days prior to landfall. Field inspection of the study sites after the passage of both hunicanes showed significant beach erosion and loss of berm elevation. Damage to infrastructure landward of the nourished beaches was minimal while non-nourished beaches located a few miles to the north and south of the renourished beaches sustained some damage. Beach profile surveys indicated that, as a general trend, beach and inner surfzone erosion was accompanied by the formation of well-developed storm bars seaward of pre-storm bars. Beach morphological responses at the town of Palm Beach were a function of offshore geomorphology of the reef system and the presence of high relief rock outcrops located within the surf zone. Sand that eroded from the renourished beach was deposited seaward of rock outcrops in the surf zone but the rock outcrops had no measurable sediment build up. Causes of the magmtude and trends of beach performance are hypothesized in an effort to explain the observed beach behavior.Hydraulic EngineeringCivil Engineering and Geoscience
Kafka on the Shore
No full textKafka On The Shore consists of three simple concrete letterforms floating on a gallery wall. Reminiscent of minimalist sculpture, the mathematical expression of the letterforms states that ‘r’ is greater than ‘g’. Despite this material simplicity, the solemn presentation of the formula suggests a sense of foreboding, a quiet menace. The work was created as a response to the economic theories of Thomas Piketty presented in his book Capital in the Twenty-First Century. The primary finding of Piketty’s data-driven research is the formula presented by the work; that historically, wealth and inequity both flourish when the rate of return on capital (r) is greater than the rate of economic growth (g). With this simple mathematical summary the book acts as a sobering indictment on the present state of economic inequality
