Wayne County Cooperative Extension A shoreline is a dynamic environment that evolves under the effects of both natural 1581 Route 88 North and human influences. Many areas along New York’s shorelines are naturally subject Newark, NY 14513-9739 315.331.8415 to erosion. Although human actions can impact the erosion process, natural coastal processes, such as wind, waves or ice movement are constantly eroding and/or building www.nyseagrant.org up the shoreline. This constant change may seem alarming, but erosion and accretion (build up of sediment) are natural phenomena experienced by the shoreline in a sort of give and take relationship. This relationship is of particular interest due to its impact on human uses and development of the shore. This fact sheet aims to introduce these processes and causes of erosion and accretion that affect New York’s shorelines.

Saving the Dust Bowl: “Big Hugh” Bennett’S Triumph Over Tragedy
Saving the Dust Bowl: “Big Hugh” Bennett’s Triumph over Tragedy Rebecca Smith Senior Historical Paper “It was dry everywhere . and there was entirely too much dust.” -Hugh Hammond Bennett, visit to the Dust Bowl, 19361 Merciless winds tore up the soil that once gave the Southern Great Plains life and hurled it in roaring black clouds across the nation. Hopelessly indebted farmers fed tumbleweed to their cattle, and, in the case of one Oklahoma town, to their children. By the 1930s, years of injudicious cultivation had devastated 100 million acres of Kansas, Oklahoma, Texas, Colorado, and New Mexico.2 This was the Dust Bowl, and it exposed a problem that had silently plagued American agriculture for centuries–soil erosion. Farmers, scientists, and the government alike considered it trivial until Hugh Hammond Bennett spearheaded a national program of soil conservation. “The end in view,” he proclaimed, “is that people everywhere will understand . the obligation of respecting the earth and protecting it in order that they may enjoy its fullness.” 3 Because of his leadership, enthusiasm, and intuitive understanding of the American farmer, Bennett triumphed over the tragedy of the Dust Bowl and the ignorance that caused it. Through the Soil Conservation Service, Bennett reclaimed the Southern Plains, reformed agriculture’s philosophy, and instituted a national policy of soil conservation that continues today. The Dust Bowl tragedy developed from the carelessness of plenty. In the 1800s, government and commercial promotions encouraged negligent settlement of the Plains, lauding 1 Hugh Hammond Bennett, Soil Conservation in the Plains Country, TD of address for Greater North Dakota Association and Fargo Chamber of Commerce Banquet, Fargo, ND., 26 Jan. -
The Soil Survey
The Soil Survey The soil survey delineates the basal soil pattern of an area and characterises each kind of soil so that the response to changes can be assessed and used as a basis for prediction. Although in an economic climate it is necessarily made for some practical purpose, it is not subordinated to the parti cular need of the moment, but is conducted in a scientific way that provides basal information of general application and eliminates the necessity for a resurvey whenever a new problem arises. It supplies information that can be combined, analysed, or amplified for many practical purposes, but the purpose should not be allowed to modify the method of survey in any fundamental way. According to the degree of detail required, soil surveys in New Zealand are classed as general, . district, or detailed. General surveys produce sufficient detail for a final map on the scale of 4 miles to an inch (1 :253440); they show the main sets of soils and their general relation to land forms; they are an aid to investigations and planning on the regional or national scale. District surveys, for maps, on the scale of 2 miles to an inch (1: 126720), show soil types or, where the pattern is detailed, combinations of types; they are designed to show the soil pattern in sufficient detail to allow the study of local soil problems and to provide a basis for assembling and distributing information in many fields such as agriculture, forestry, and engineering. Detailed surveys, mostiy for maps on the scale of 40 chains to an inch (1 :31680), delineate soil types and land-use phases, and show the soil pattern in relation to farm boundaries and subdivisional fences. -
Hydrogeology of Near-Shore Submarine Groundwater Discharge
Hydrogeology and Geochemistry of Near-shore Submarine Groundwater Discharge at Flamengo Bay, Ubatuba, Brazil June A. Oberdorfer (San Jose State University) Matthew Charette, Matthew Allen (Woods Hole Oceanographic Institution) Jonathan B. Martin (University of Florida) and Jaye E. Cable (Louisiana State University) Abstract: Near-shore discharge of fresh groundwater from the fractured granitic rock is strongly controlled by the local geology. Freshwater flows primarily through a zone of weathered granite to a distance of 24 m offshore. In the nearshore environment this weathered granite is covered by about 0.5 m of well-sorted, coarse sands with sea water salinity, with an abrupt transition to much lower salinity once the weathered granite is penetrated. Further offshore, low-permeability marine sediments contained saline porewater, marking the limit of offshore migration of freshwater. Freshwater flux rates based on tidal signal and hydraulic gradient analysis indicate a fresh submarine groundwater discharge of 0.17 to 1.6 m3/d per m of shoreline. Dissolved inorganic nitrogen and silicate were elevated in the porewater relative to seawater, and appeared to be a net source of nutrients to the overlying water column. The major ion concentrations suggest that the freshwater within the aquifer has a short residence time. Major element concentrations do not reflect alteration of the granitic rocks, possibly because the alteration occurred prior to development of the current discharge zones, or from elevated water/rock ratios. Introduction While there has been a growing interest over the last two decades in quantifying the discharge of groundwater to the coastal zone, the majority of studies have been carried out in aquifers consisting of unlithified sediments or in karst environments. -

JAZZ WRITING? I am one of Mr. Turley's "few people" who follow The New Yorker and are jazz lovers, and I find in Whitney Bal- liett's writing some of the sharpest and best jazz criticism in the field. He has not been duped with "funk" in its pseudo-gospel hard-boppish world, or- with the banal playing and writing of some of the "cool school" Californians. He does believe, and rightly so, that a fine jazz performance erases the bound• aries of jazz "movements" or fads. He seems to be able to spot insincerity in any phalanx of jazz musicians. And he has yet to be blinded by the name of a "great"; his recent column on Bil- lie Holiday is the most clear-headed analysis I have seen, free of the fan- magazine hero-worship which seems to have been the order of the day in the trade. It is true that a great singer has passed away, but it does the late Miss Holiday's reputation no good not to ad• LETTERS mit that some of her later efforts were (dare I say it?) not up to her earlier work in quality. But I digress. In Mr. Balliett's case, his ability as a critic is added to his admitted "skill with words" (Turley). He is making a sincere effort to write rather than play jazz; to improvise with words,, rather than notes. A jazz fan, in order to "dig" a given solo, unwittingly knows a little about the equipment: the tune being improvised to, the chord struc• ture, the mechanics of the instrument, etc. -

Under evaluation is a distinct coastal boulder bed (CBB) derived from banded rhyolite with boulders arrayed in a partial-ring configuration against one side of the headland on Ensenada Almeja (Clam Bay) north of Loreto. Preconditions related to the thickness of rhyolite flows and vertical fissures that intersect the flows at right angles along with the specific gravity of banded rhyolite delimit the size, shape and weight of boulders in the Almeja CBB. Mathematical formulae are applied to calculate the wave height generated by storm surge impacting the headland. The average weight of the 25 largest boulders from a transect nearest the bedrock source amounts to 1200 kg but only 30% of the sample is estimated to exceed a full metric ton in weight. -
Hugh Hammond Bennett
Hugh Hammond Bennett nrcs.usda.gov/wps/portal/nrcs/detail/national/about/history/ "Father of Soil Conservation" Hugh Hammond Bennett (April 15 1881-7 July 1960) was born near Wadesboro in Anson County, North Carolina, the son of William Osborne Bennett and Rosa May Hammond, farmers. Bennett earned a bachelor of science degree an emphasis in chemistry and geology from the University of North Carolina in June 1903. At that time, the Bureau of Soils within the U.S. Department of Agriculture (USDA) had just begun to make county-based soil surveys, which would in the time be regarded as important American contributions to soil science. Bennett accepted a job in the bureau headquarters' laboratory in Washington, D.C., but agreed first to assist on the soil survey of Davidson County, Tennessee, beginning 1 July 1903. The acceptance of that task, in Bennett's words, "fixed my life's work in soils." The outdoor work suited Bennett, and he compiled a number of soil surveys. The 1905 survey of Louisa County, Virginia, in particular, profoundly affected Bennett. He had been directed to the county to investigate its reputation of declining crop yields. As he compared virgin, timbered sites to eroded fields, he became convinced that soil erosion was a problem not just for the individual farmer but also for rural economies. While this experience aroused his curiosity, it was, according to Bennett's recollection shortly before his death, Thomas C. Chamberlain's paper on "Soil Wastage" presented in 1908 at the Governors Conference in the White House (published in Conference of Governors on Conservation of Natural Resources, ed. -

Pedology is the study of soils as they occur on the landscape. A central goal of pedological research is improve holistic understanding of soils as real systems within agronomic, ecological and environmental contexts. Attaining such understanding requires integrating all aspects of soil science. Soil genesis, classification, and survey are traditional pedological topics. These topics require astute field assessment of soil http://soils.ifas.ufl.edu morphology and composition. However, remote sensing technology, digitally-linked geographic data, and powerful computer-driven geographic information systems (GIS) have been exploited in recent years to extend pedological applications beyond EDITORS: traditional field-based reconnaissance. These tools have led to landscape modeling and development of digital soil mapping techniques. Susan Curry [email protected] Florida State soil is “Myakka” fine sand, a flatwood soil, classified as Spodosols. Myakka is pronounced ‘My-yak-ah’ - a Native American word for Big Waters. Reflecting Dr. Vimala Nair our department’s mission, we named our newsletter as “Myakka”.
