In order to study the effects of trenching on the water table in the more complicated hydrologic system in northeast Mississippi, a two-dimensional cross-sectional digital model was developed from an existing two-dimensional digital model.

Analyses are made by using a sodium carbonate-potassium carbonate fusion and a citric acid dissolution of the fuseate. Prior to determining the fluorine concentration by a standard-addition procedure, sodium citrate buffer is added to the solution. The proposed method yields fluorine values in agreement with known values for standard rocks.

In previous studies we have shown by small angle X-ray scattering that the size of these aggregates is a function of pH.

The principal feature of both the percentage and influx pollen diagrams is the replacement of arboreal pollen, primarily&nbsp;</span><i>Quercus, Fraxinus</i><span>, and&nbsp;</span><i>Cephalanthus</i><span>, with Gramineae and NAP between 8700 and 5000 years BP. This vegetation shift is interpreted as reflecting a decrease in the extent of the Old Field swamp and its associated bottomland forest species along with the expansion of a grass-dominated herb community, as a result of a reduction in available ground water. The desiccation of the swamp during this period indicates a reduction in precipitation within the ground-water source area and a shift to a drier climate in the southern Midwest. The pollen suggests that the lowest water levels and driest climate in southeastern Missouri lasted from 8700 to 6500 years BP, at which time there is a partial reappearance of swamp species. Relatively dry conditions, however, continued until at least 5000 years BP. Although pollen influx data are lacking from the upper part of the profile, the relative pollen frequencies suggest an increase in trees after 5000 BP. The replacement of the arboreal vegetation by grasses and herbs between 8700 and 5000 years BP reflects the period of maximum expansion of the Prairie Peninsula in southeastern Missouri. The Old Field swamp provides the first pollen evidence that the vegetational changes along the southern border of the Prairie Peninsula were chronologically similar to those on the northern and northeastern margins.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0033-5894(77)90074-6","issn":"00335894","usgsCitation":"King, J., and Allen, W., 1977, A Holocene vegetation record from the Mississippi River Valley, southeastern Missouri: Quaternary Research, v. 8, no. 3, p. 307-323, https://doi.org/10.1016/0033-5894(77)90074-6.","productDescription":"17 p.","startPage":"307","endPage":"323","costCenters":[],"links":[{"id":219420,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Missouri","otherGeospatial":"southeastern Missouri","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -91.07054667773045,\n              38.09014494828594\n            ],\n            [\n              -90.54206225223642,\n              36.702615368211454\n            ],\n            [\n              -90.05604334541198,\n              36.38820532984435\n            ],\n            [\n              -90.41676976336173,\n              36.05702886964755\n            ],\n            [\n              -90.35741038138397,\n              35.93668412213937\n            ],\n            [\n              -89.0633434281007,\n              35.98390470405607\n            ],\n            [\n              -89.14074839381657,\n              37.29856968925574\n            ],\n            [\n              -89.94576507260174,\n              38.09292648454809\n            ],\n            [\n              -91.07054667773045,\n              38.09014494828594\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"8","issue":"3","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"5059e2e5e4b0c8380cd45cf9","contributors":{"authors":[{"text":"King, J.E.","contributorId":99695,"corporation":false,"usgs":true,"family":"King","given":"J.E.","email":"","affiliations":[],"preferred":false,"id":357556,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Allen, W.H.

These basal loess beds contain artifacts for which radiocarbon dates and typologic correlations suggest a time range of perhaps 12,000–9000 yr ago. A long subsequent episode of cultural sterility was associated with waning loess deposition and development of a cryoturbated tundra soil above shallow permafrost.

The silt deposit caps a 50-m-high terrace and consists of three units. An upper layer 1–2 m thick overlies a 10–15-m-thick brownish to black silt layer. The lower silt layer is greenish to gray and about 15 m thick. All the silt is well sorted with 60% of the particles falling between 0.005 and 0.5 mm in diameter and is generally chemically and mineralogically homogeneous. The middle unit contains may extinct vertebrate mammal remains and ice wedges. The lower unit contains little vegetation and no ice wedges. The silt is widespread and exists as a loamy blanket on terraces at various elevations on both sides of the lower Aldan River. The origin of the silt blanket of late-Quaternary age in central Yakutia has long been controversial. Various hypotheses have been suggested, including lacustrine and alluvial, as well as frost-action origins. It is sometimes referred to as loess-like loam. Péwé believes the silt at Mamontova Gora is loess, some of which has been retransported very short distances by water. The silt probably was blown from wide, braided, unvegetated flood plains of rivers draining nearby glaciers. The silt deposits are late Quaternary in age and probably associated with the Maximum glaciation (Samarov) and Sartan and Syryan glaciations of Wisconsinan age. On the basis of biostratigraphy, 10 radiocarbon dates, and their relation to the nearby glacial record, it is felt that the upper unit at Mamontova Gora is Holocene and the middle unit is Wisconsinan. The youngest date available from the middle unit at this particular location is 26,000 years. Dates greater than 56,000 years were obtained in the lower part of the middle unit. The lower unit is definitely beyond the range of radiocarbon dating and probably is older than the last interglacial. The sediment, fauna, ice wedges, stratigraphy, and age of perennially frozen slit deposits in central Alaska are remarkably similar to those of the deposits exposed in central Yakutia. Both areas consist of unglaciated rolling lowlands and river terraces surrounded by high mountains that were extensively glaciated in Pleistocene time. The glaciers extended from the high mountains to the edges of the ranges. In both regions, extensively braided, silt-charged rivers drained the mountains and flowed through the lowlands on their way to the sea. It follows that there should be a similar late-Quaternary history.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0033-5894(77)90056-4","issn":"00335894","usgsCitation":"Pewe, T.L., Journaux, A., and Stuckenrath, R., 1977, Radiocarbon dates and late-Quaternary stratigraphy from Mamontova Gora, unglaciated central Yakutia, Siberia, U.S.S.R.: Quaternary Research, v. 8, no. 1, p. 51-63, https://doi.org/10.1016/0033-5894(77)90056-4.","productDescription":"13 p.","startPage":"51","endPage":"63","costCenters":[],"links":[{"id":219488,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Russia","otherGeospatial":"Siberia","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              67.65387774806533,\n              81.31005430433049\n            ],\n            [\n              67.65387774806533,\n              49.88407908375689\n            ],\n            [\n              105.33401707666286,\n              49.88407908375689\n            ],\n            [\n              105.33401707666286,\n              81.31005430433049\n            ],\n            [\n              67.65387774806533,\n              81.31005430433049\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"8","issue":"1","noUsgsAuthors":false,"publicationDate":"2017-01-20","publicationStatus":"PW","scienceBaseUri":"505a93d7e4b0c8380cd81067","contributors":{"authors":[{"text":"Pewe, T.

The thick welt of sediment at the base of the Siberian margin may be the result of sediment loading or tectonic depression prior to Late Cenozoic time.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0025-3227(77)90074-3","issn":"00253227","usgsCitation":"Rabinowitz, P.D., and Cooper, A., 1977, Structure and sediment distribution in the western Bering Sea: Marine Geology, v. 24, no. 4, p. 309-320, https://doi.org/10.1016/0025-3227(77)90074-3.","productDescription":"12 p.","startPage":"309","endPage":"320","costCenters":[],"links":[{"id":219662,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Russia, United States","state":"Alaska","otherGeospatial":"western Bering Sea","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -179.9,\n              56.285168320056385\n            ],\n            [\n              -179.9,\n              51.00071364602036\n            ],\n            [\n              -174.83958193767174,\n              51.00071364602036\n            ],\n            [\n              -174.83958193767174,\n              56.285168320056385\n            ],\n            [\n              -179.9,\n              56.285168320056385\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              179.9,\n              56.28905975329704\n            ],\n            [\n              164.84405712674976,\n              56.28905975329704\n            ],\n            [\n              164.84405712674976,\n              50.95540695542479\n            ],\n            [\n              179.9,\n              50.95540695542479\n            ],\n            [\n              179.9,\n              56.28905975329704\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"24","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9c2ce4b08c986b31d2fe","contributors":{"authors":[{"text":"Rabinowitz, P.
