A recent study was conducted to delineate the distribution of salinity in relation to the local hydrogeology and assess the potential processes that might control (or have affected) the distribution of salinity in the Floridan aquifer system. The Floridan aquifer system in the study area consists of the Upper Floridan aquifer, middle confining unit, and Lower Floridan aquifer and ranges in age from Paleocene to Oligocene. Included at its top is part of a lowermost Hawthorn Group unit referred to as the basal Hawthorn unit. The thickness of this basal unit is variable, ranging from about 30 to 355 feet; areas where this unit is thick were paleotopographic lows during deposition of the unit. The uppermost permeable zones in the Upper Floridan aquifer occur in close association with an unconformity at the base of the Hawthorn Group; however, the highest of these zones can be up in the basal unit. A dolomite unit of Eocene age generally marks the top of the Lower Floridan aquifer, but the top of this dolomite unit has a considerable altitude range: from about 1,200 to 2,300 feet below sea level. Additionally, where the dolomite unit is thick, its top is high and the middle confining unit of the Floridan aquifer system, as normally defined, probably is not present. An upper zone of brackish water and a lower zone of water with salinity similar to that of seawater (saline-water zone) are present in the Floridan aquifer system. The brackish-water and saline-water zones are separated by a transition zone (typically 100 to 200 feet thick) in which salinity rapidly increases with depth. The transition zone was defined by using a salinity of 10,000 mg/L (milligrams per liter) of dissolved-solids concentration (about 5,240 mg/L of chloride concentration) at its top and 35,000 mg/L of dissolved-solids concentration (about 18,900 mg/L of chloride concentration) at its base. The base of the brackish-water zone and the top of the saline-water zone were approximately determined mostly by means of resistivity geophysical logs. The base of the brackish-water zone in the study area ranges from about 1,600 feet below sea level near the coast to almost 2,200 feet below sea level in extreme southwestern Palm Beach County. In an area that is peripheral to Lake Okeechobee, the boundary unexpectedly rises to perhaps as shallow as 1,800 feet below sea level. In an upper interval of the brackish-water zone within the Upper Floridan aquifer, chloride concentration of water ranges from 490 to 8,000 mg/L. Chloride concentration correlates with the altitude of the basal contact of the Hawthorn Group, with concentration increasing as the altitude of this contact decreases. Several areas of anomalous salinity where chloride concentration in this upper interval is greater than 3,000 mg/L occur near the coast. In most of these areas, salinity was found to decrease with depth from the upper interval to a lower interval within the brackish-water zone: a reversal of the normal salinity trend within the zone. These areas are also characterized by an anomalously low altitude of the base of the brackish-water zone, and a much greater thickness of the transition zone than normal. These anomalies could be the result of seawater preferentially invading zones of higher permeability in the Upper Floridan aquifer during Pleistocene high stands of sea level and incomplete flushing of this high salinity water by the present-day flow system.

The High Plains aquifer underlies an area of about 174,000 square miles in parts of eight States. Because of its large size, the High Plains aquifer has been divided into three regions: the Southern High Plains, Central High Plains, and Northern High Plains. Although an assessment of water quality in each of the three regions is planned, the initial focus will be the Central High Plains aquifer. Anyone who has flown over the Central High Plains in the summer and has seen the large green circles associated with center pivot sprinklers knows that irrigated agriculture is a widespread land use. Pesticides and fertilizers applied on those irrigated fields will not degrade ground-water quality if they remain in or above the root zone. However, if those chemicals move downward through the unsaturated zone to the water table, they may degrade the quality of the ground water. Water is the principal agent for transporting chemicals from land surface to the water table, and in the semiarid Central High Plains, irrigation often represents the most abundant source of water during the growing season. One objective of NAWQA's High Plains Regional Ground-Water study is to evaluate the effect of irrigated agriculture on the quality of recently recharged water in the Ogallala Formation of the Central High Plains aquifer. The Ogallala Formation is the principal geologic unit in the Central High Plains aquifer, and it consists of poorly sorted clay, silt, sand, and gravel that generally is unconsolidated (Gutentag and others, 1984). Approximately 23 percent of the cropland overlying the Ogallala Formation is irrigated (U.S. Department of Agriculture, 1999). The NAWQA Program generally defines recently recharged ground water to be water recharged in the last 50 years. The water table in the Ogallala Formation is separated from overlying land-use practices by as much as 400 feet of unsaturated sediments. Consequently, one may hypothesize that recently recharged water is not present in the formation. The U.S. Geological Survey conducted a reconnaissance study in 1999 to establish (a) if recently recharged water was present in the Ogallala Formation underlying irrigated cropland and (b) if agricultural land-use practices affect water quality. Results from the reconnaissance study will be used to determine whether a full-scale land-use study is warranted.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/fs00900","usgsCitation":"McMahon, P.B., 2000, A reconnaissance study of the effect of irrigated agriculture on water quality in the Ogallala Formation, Central High Plains Aquifer: U.S. Geological Survey Fact Sheet 009-00, 6 p., https://doi.org/10.3133/fs00900.","productDescription":"6 p.","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":595,"text":"U.S. Geological Survey","active":false,"usgs":true}],"links":[{"id":34091,"rank":299,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/2000/0009/report.pdf","text":"Report","size":"2.9 MB","linkFileType":{"id":1,"text":"pdf"},"description":"FS 2000-0009"},{"id":124403,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/fs/2000/0009/report-thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a8512","contributors":{"authors":[{"text":"McMahon, Peter B. 0000-0001-7452-2379 pmcmahon@usgs.gov","orcid":"https://orcid.org/0000-0001-7452-2379","contributorId":724,"corporation":false,"usgs":true,"family":"McMahon","given":"Peter","email":"pmcmahon@usgs.gov","middleInitial":"B.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":153167,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This paper makes a preliminary comparison of the methodologies and results of the two products. The DISCover methodology employed an unsupervised clustering classification scheme on a per-continent basis using 12 monthly maximum NDVI composites as inputs. The UMd approach employed a supervised classification tree method in which temporal metrics derived from all AVHRR bands and the NDVI were used to predict class membership across the entire globe. The DISCover map uses the IGBP classification scheme, while the UMd map employs a modified IGBP scheme minus the classes of permanent wetlands, cropland/natural vegetation mosaic and ice and snow. Global area totals of aggregated vegetation types are very similar and have a per-pixel agreement of 74%. For tall versus short/no vegetation, the per-pixel agreement is 84%. For broad vegetation types, core areas map similarly, while transition zones around core areas differ significantly. This results in high regional variability between the maps. Individual class agreement between the two 1 km maps is 49%. Comparison of the maps at a nominal 0.5 resolution with two global ground-based maps shows an improvement of thematic concurrency of 46% when viewing average class agreement. The absence of the cropland mosaic class creates a difficulty in comparing the maps, due to its significant extent in the DISCover map. The DISCover map, in general, has more forest, while the UMd map has considerably more area in the intermediate tree cover classes of woody savanna/ woodland and savanna/wooded grassland.</span></p>","language":"English","publisher":"Taylor & Francis","doi":"10.1080/014311600210218","usgsCitation":"Hansen, M., and Reed, B., 2000, A comparison of the IGBP DISCover and University of Maryland 1 km global land cover products: International Journal of Remote Sensing, v. 21, no. 6-7, p. 1365-1373, https://doi.org/10.1080/014311600210218.","productDescription":"9 p.","startPage":"1365","endPage":"1373","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":307230,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","issue":"6-7","noUsgsAuthors":false,"publicationDate":"2010-11-25","publicationStatus":"PW","scienceBaseUri":"55dc4028e4b0518e354d10cf","contributors":{"authors":[{"text":"Hansen, M.C.","contributorId":69690,"corporation":false,"usgs":false,"family":"Hansen","given":"M.C.","email":"","affiliations":[{"id":33433,"text":"University of Maryland, College Park","active":true,"usgs":false}],"preferred":false,"id":569372,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reed, B.","contributorId":62352,"corporation":false,"usgs":true,"family":"Reed","given":"B.","email":"","affiliations":[],"preferred":false,"id":569373,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The death toll exceeded 2,300 with more than 10,000 injured.

The result was immediately disseminated to governmental emergency response agencies electronically in four ways, by e-mail, World Wide Web, fax, and pager. This rapid information system has been successfully operating in Taiwan for more than four years. During the Chi-Chi earthquake, the rapid availability of earthquake information facilitated the emergency response. The RTD system worked very well throughout the whole aftershock sequence (several aftershocks had local magnitude of 6 or larger). Again this timely information was useful to the emergency response teams.

The eastern BTFZ is dominated by the ∼150&nbsp;km long transform-parallel Blanco Ridge (BR) which is a right-lateral strike-slip fault bordered to the east and west by the Gorda and Cascadia Depressions. Acoustic locations, fault-parameter information, and slip vector estimates of 43 earthquakes (</span><i>M</i><span>&nbsp;</span><sub>w</sub><span>≥3.8) that occurred along the eastern BTFZ over the last 5 years reveal that the Blanco Ridge is a high-angle right-lateral strike-slip fault, with a small component of dip-slip motion, where the Juan de Fuca plate is the hanging wall relative to the Pacific plate. Furthermore, the Cascadia and Gorda basins are undergoing normal faulting with extension predominantly oblique to the transform trend. Seafloor submersible observations agree with previous hypotheses that the active transform fault trace is the elongate basin that runs the length of the BR summit. Brecciated and undeformed basalt, diabase, and gabbro samples were collected at the four submersible survey sites along the Blanco Ridge. These petrologic samples indicate the Blanco Ridge is composed of an ocean crustal sequence that has been uplifted and highly fractured. The petrologic samples also appear to show an increase in elevation of the crustal section from east to west along the Blanco Ridge, with gabbros exposed at a shallower depth farther west along the southern (Pacific plate side) BR ridge flank. Further supporting evidence for BR uplift exists in the seismic reflection profiles across the BR showing uplift of turbidite sequences along the north and south ridge base, and gravity and magnetics profiles that indicate possible basement uplift and a low-density zone centered on the ridge's Pacific plate side. The BR formation mechanism preferred here is first, uplift achieved partially through strike-slip motion (with a small dip-slip component). Second, seawater penetration along the fault into the lower crust upper mantle, which then enhanced formation and intrusion of a mantle-derived serpentinized-peridotite diapir into the shallow ocean crust, causing further uplift along the fault.</span></p>","language":"English","publisher":"Springer Nature","doi":"10.1023/A:1026545910893","usgsCitation":"Dziak, R., Fox, C., Embley, R., Nabelek, J., Braunmiller, J., and Koski, R.A., 2000, Recent tectonics of the Blanco Ridge, eastern blanco transform fault zone: Marine Geophysical Research, v. 21, p. 423-450, https://doi.org/10.1023/A:1026545910893.","productDescription":"28 p.","startPage":"423","endPage":"450","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":374857,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"21","noUsgsAuthors":false,"publicationStatus":"PW","contributors":{"authors":[{"text":"Dziak, Robert","contributorId":217088,"corporation":false,"usgs":false,"family":"Dziak","given":"Robert","affiliations":[{"id":39567,"text":"NOAA/PMEL","active":true,"usgs":false}],"preferred":false,"id":789245,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fox, C.G.","contributorId":60315,"corporation":false,"usgs":true,"family":"Fox","given":"C.G.","email":"","affiliations":[],"preferred":false,"id":789246,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Embley, R.","contributorId":43966,"corporation":false,"usgs":true,"family":"Embley","given":"R.","email":"","affiliations":[],"preferred":false,"id":789247,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nabelek, J.L.","contributorId":27316,"corporation":false,"usgs":true,"family":"Nabelek","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":789248,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Braunmiller, Jochen","contributorId":224718,"corporation":false,"usgs":false,"family":"Braunmiller","given":"Jochen","affiliations":[],"preferred":false,"id":789249,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Koski, Randolph A. rkoski@usgs.gov","contributorId":2949,"corporation":false,"usgs":true,"family":"Koski","given":"Randolph","email":"rkoski@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":789250,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Agriculture constitutes 93 percent of all land use in eastern Iowa. As part of the U.S. Geological Survey National Water Quality Assessment Program, water samples were collected (typically monthly) from six small and six large watersheds in eastern Iowa between March 1996 and September 1997. A Geographic Information System (GIS) was used to determine land use and quantify inputs of nitrogen and phosphorus within the study area. Streamliow from the watersheds is to the Mississippi River. Chemical fertilizer and animal manure account for 92 percent of the estimated total nitrogen and 99.9 percent of the estimated total phosphorus input in the study area. Total nitrogen and total phosphorus loads for 1996 were estimated for nine of the 12 rivers and creeks using a minimum variance unbiased estimator model. A seasonal pattern of concentrations and loads was observed. The greatest concentrations and loads occur in the late spring to early summer in conjunction with row-crop fertilizer applications and spring nmoff and again in the late fall to early winter as vegetation goes into dormancy and additional fertilizer is applied to row-crop fields. The three largest rivers in eastern Iowa transported an estimated total of 79,000 metric tons of total nitrogen and 6,800 metric tons of total phosphorus to the Mississippi River in 1996. The estimated mass of total nitrogen and total phosphorus transported to the Mississippi River represents about 19 percent of all estimated nitrogen and 9 percent of all estimated phosphorus input to the study area.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal

The samples ranged in burial\r\ntemperatures from 40\r\n?\r\nto 220\r\n?\r\nC, and contained hydrogen-poor\r\nto hydrogen-rich organic matter (OM), based on OM visual typing\r\nand a correlation of elemental kerogen hydrogen to carbon\r\nratios with ROCK-EVAL hydrogen indices.\r\nBy extractable bitumen measurements, rocks with hydrogen-\r\npoor OM in the Los Angeles Basin began mainstage hydrocarbon\r\n(HC) generation by 90\r\n?\r\nC. The HC concentrations\r\nmaximized by 165\r\n?\r\nC, and beyond 165\r\n?\r\nC, HC and bitumen concentrations\r\nand ROCK-EVAL hydrogen indices all began\r\ndecreasing to low values reached by 220\r\n?\r\nC, where HC generation\r\nwas largely complete. Rocks with hydrogen-poor OM in\r\nthe Southern San Joaquin Valley Basin commenced mainstage\r\nHC generation at 135\r\n?\r\nC and HC concentrations maximized by\r\n180\r\n?\r\nC. Above 180\r\n?\r\nC, HC and bitumen concentrations and\r\nROCK-EVAL hydrogen indices all decreased to low values\r\nreached by 214\r\n?\r\nC, again the process of HC generation being\r\nlargely complete. In both cases, bell-shaped HC-generation\r\ncurves were present versus depth (burial temperature). Mainstage\r\nHC generation had not yet begun in Ventura Basin rocks\r\nwith hydrogen-poor OM by 140\r\n?\r\nC. The apparent lower temperature\r\nfor initiation of mainstage generation in the Los Angeles\r\nBasin is attributed to very recent cooling in that basin from\r\nmeteoric-water flow. Thus, HC generation there most probably\r\noccurred at higher burial temperatures.\r\nIn contrast, mainstage HC generation, and all aspects of\r\norganic metamorphism, were strongly suppressed in rocks with\r\nhydrogen-rich OM at temperatures as high as 198\r\n?\r\nC. For example,\r\nshales from the Wilmington field (Los Angeles Basin) from\r\n180\r\n?\r\nto 198\r\n?\r\nC retained ROCK-EVAL hydrogen indices of 550-\r\n700 and had saturated-HC coefficients of only 4-15 mg/g\r\norganic carbon. The rocks with hydrogen-rich OM were subjected\r\nto the same burial conditions as the rocks with hydrogenpoor\r\nOM. We attribute this suppression of organic metamorphism\r\nin this study primarily to much stronger bonds in the\r\nhydrogen-rich OM compared to the bonds in hydrogen-poor\r\nOM. Trends in bitumen compositions (qualitative characteristics)\r\nversus burial temperature were also very different for rocks\r\nwith hydrogen-poor OM compared to that in rocks with hydrogen-\r\nrich OM. This observation demonstrated that the two OM\r\ntypes also had significantly different reaction pathways, in addition\r\nto different reaction kinetics. Strong exploration implications\r\narise from these observations.\r\nAbove 40?C, but before mainstage HC generation, a lowtemperature\r\n(pre-mainstage) HC generation occurred in all\r\nrocks, and all OM types, studied. This low-temperature generation\r\nresulted in significant qualitative changes in the bitumen\r\nand HCS (hydrocarbons) from rocks of all OM types, especially\r\nin rocks with hydrogen-rich OM, from 40\r\n?\r\nto 70\r\n?\r\nC. This, and\r\nprevious studies, document that very high carbon-normalized\r\nconcentrations of indigenous bitumen and HCS occur in late\r\nNeogene immature rocks of any OM type in all southern California\r\nbasins. This characteristic is attributed to the low-temperature\r\ngeneration occurring in both sulfur-poor and sulfur-rich\r\nkerogens, which originally had unusually high concentrations of\r\nweak (15-40 Kcal/mole) bonds. These observations and considerations\r\nhave marked relevance to exploration regarding the possible\r\nformation of commercial oil deposits at immature ranks in\r\nthese basins. Other significant geochemical observations also\r\nresult from this study.","language":"ENGLISH","publisher":"U.S. Department of the Interior, U.S. Geological Survey,","doi":"10.3133/b2174B","usgsCitation":"Price, L.C., 2000, Organic metamorphism in the California petroleum basins; Chapter B, Insights from extractable bitumen and saturated hydrocarbons (Version 1.0): U.S. Geological Survey Bulletin 2174, 33 p., https://doi.org/10.3133/b2174B.","productDescription":"33 p.","costCenters":[],"links":[{"id":164683,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":3415,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/bul/b2174-b/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db63576b","contributors":{"authors":[{"text":"Price, Leigh C.","contributorId":39379,"corporation":false,"usgs":true,"family":"Price","given":"Leigh","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":214770,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The sediment laboratories currently in operation constitute the entire USGS national laboratory system for sediment analyses. As with all environmental data, physical sediment data can be expected to contain a certain amount of difference, whether the difference resulted from the collecting, transporting, or analyzing of the sample. Because it is important to know how each laboratory is performing, the USGS initiated the Sediment Laboratory Quality-Assurance (SLQA) project in August 1996. From August 1996 through June 1998, five studies were made, the results of which are the basis of this report.</p>\n<p>The focus of the project is on quantitative analyses done on water-sediment mixtures to derive suspended-sediment concentrations, sediment-mass determinations, and sand/fine separations. For the purpose of this report, all mass determinations are net values&mdash;the tare weight of the container is excluded. The fine-size material is defined as particles sieved to a size of less than 62 micrometers (&micro;m) and sand-size material is defined as particles sieved to a size of between 63 and 125 &micro;m. Also, in this report, class 1 samples are defined as samples containing 50 to 100 milligrams (mg) of fine-size material, class 2 samples are defined as samples containing 101 to 300 mg of fine-size material, and class 3 samples are defined as samples containing 2,200 to 3,200 mg of fine-size material. In studies 96-1 through 98-1, the amount of sand added to each sample ranged from 9 to 28 percent of the mass of fine-size material in each sample class.</p>\n<p>Analytical results from all sediment quality-control samples are compiled and statistically summarized by the USGS, Branch of Quality Systems, both on an intra- and interlaboratory basis. When evaluating these data, the reader needs to keep in mind that every measurement has an error component associated with it. It is premature to use the data from the first five SLQA studies to judge any of the laboratories as performing in an unacceptable manner. There were, however, some notable differences in the results for the 12 laboratories that participated in the five SLQA studies. For example, the overall median percent difference for suspended-sediment concentration on an individual laboratory basis ranged from &ndash;18.04 to &ndash;0.33 percent. Five of the 12 laboratories had an overall median percent difference for suspended-sediment concentration of &ndash;2.02 to &ndash;0.33 percent. There was less variability in the median difference for the measured fine-size material mass. The overall median percent difference for fine-size material mass ranged from &ndash;10.11 to &ndash;4.27 percent. Except for one laboratory, the median difference for fine-size material mass was within a fairly narrow range of &ndash;6.76 to &ndash;4.27 percent. The median percent difference for sand-size material mass differed among laboratories more than any other physical sediment property measured in the study. The overall median percent difference for the sand-size material mass ranged from &ndash;1.49 percent to 26.39 percent. Five of the nine laboratories that do sand/fine separations had overall median percent differences that ranged from &ndash;1.49 to 2.98 percent for sand-size material mass. Careful review of the data reveals that certain laboratories consistently produced data within statistical control limits for some or all of the physical sediment properties measured in this study, whereas other laboratories occasionally produced data that exceeded the control limits.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Denver, CO","doi":"10.3133/wri994184","usgsCitation":"Gordon, J.D., Newland, C.A., and Gagliardi, S.T., 2000, Laboratory performance in the Sediment Laboratory Quality-Assurance Project, 1996-98: U.S. Geological Survey Water-Resources Investigations Report 99-4184, Report: vi, 39 p.; Figures, https://doi.org/10.3133/wri994184.","productDescription":"Report: vi, 39 p.; Figures","onlineOnly":"N","additionalOnlineFiles":"N","temporalStart":"1996-08-01","temporalEnd":"1998-06-30","costCenters":[],"links":[{"id":158967,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri994184.PNG"},{"id":323272,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/wri/1999/4184/figures.pdf","text":"Figures","linkFileType":{"id":1,"text":"pdf"}},{"id":9915,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://bqs.usgs.gov/slqa/slqa_96-98.html","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b44c8","contributors":{"authors":[{"text":"Gordon, John D. 0000-0001-8396-8524 jgordon@usgs.gov","orcid":"https://orcid.org/0000-0001-8396-8524","contributorId":347,"corporation":false,"usgs":true,"family":"Gordon","given":"John","email":"jgordon@usgs.gov","middleInitial":"D.","affiliations":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":197997,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Newland, Carla A.","contributorId":97536,"corporation":false,"usgs":true,"family":"Newland","given":"Carla","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":197999,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gagliardi, Shane T.","contributorId":82358,"corporation":false,"usgs":true,"family":"Gagliardi","given":"Shane","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":197998,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The topography\nis shown by contours. These are\nimaginary lines that follow the ground\nsurface at a constant elevation; they are\nusually printed in brown, in two thicknesses.\nThe heavier lines are called index\ncontours, and they are usually marked\nwith numbers that give the height in feet\nor meters. The contour interval, a set difference\nin elevation between the brown\nlines, varies from map to map; its value is\ngiven in the margin of each map. Contour\nlines that are close together represent\nsteep slopes.\nNatural and manmade features are represented\nby colored areas and by a set of\nstandard symbols on all U.S . Geological\nSurvey (USGS) topographic maps.\nWoodlands, for instance, are shown in a\ngreen tint; waterways, in blue. Buildings\nmay be shown on the map as black\nsquares or outlines.
