“…Despite the tropical environment, alternating conditions of heavy rainfalls and prolonged drought periods in the DF favor the preservation of clay minerals with greater activity in soils with internal drainage restrictions, as in FF (Anjos et al, 2007). In general, the spectral curves of FF are quite similar to those described by Demattê et al (2012b).…”

Traditional method of soil survey is expensive, slow, and must be carried out by experienced researchers. Thus, advances in soil observation technologies and the need to obtain information quickly by modern techniques have intensified the use of proximal sensing. This study characterized surface reflectance spectra (A horizon) and related them to traditional soil classification, based on morphological, physical, and chemical properties of representative pedogenetic profiles, developed in two toposequences of the Distrito Federal, Brazil. In the toposequences, 15 soil profiles were selected for a complete morphological description and sampling for laboratory analyses. Soil-landscape relationships were established, and profiles were classified to the fourth level of the Brazilian Soil Classification System (SiBCS). Classes of similar soils were grouped based on their surface spectra, resulting in spectral curves of 10 representative soils in the studied area. The Morphological Interpretation of Reflectance Spectrum (MIRS) and second derivative of the Kubelka-Munk (KM) function were applied to the soil spectra. The clustered soils were similar, mainly in terms of color, textural class, and organic matter content. Groups based on soil physical and chemical properties and on surface and subsurface colors were similar to those determined by surface reflectance. The identification of soil-landscape relationships was fundamental to understand the genesis and distribution of the soils, which had similar chemical and physical properties to their parent materials. The analysis of clusters based on soil surface reflectance proved efficient in determining groups of soil classes with similar properties. Surface reflectance data were related to the soil surface and subsurface properties determined by traditional soil sample analyses, since the two approaches formed similar groups. The simultaneous interaction of soil properties was assessed by MIRS analysis, while the second derivative of the KM function adequately quantified the mineralogy of the spectra.

“…Apesar dos depósitos sedimentares provenientes do período quaternário caracterizarem bem a unidade morfoestrutural que é a Planície Costeira, está também apresenta outro tipo de cobertura sedimentar bem característica proveniente do período terciário, o Grupo Barreiras. Este grupo sedimentar é fruto, principalmente, da sedimentação fluvial ocorrida na era Cenozoica, no período Terciário, com constituição sedimentar no estado do Amapá de arenito e argilito com tonalidades variadas (amarelo-avermelhada), com rochas pouco consolidadas, sob a forma de platôs baixos e dissecados ou relevo colinoso (Demattê et al, 2012).…”

A Zona Costeira Amapaense é uma área de com diversidade ambientes, fauna, flora e recursos naturais. Por estes fatores, esta é uma região explorada, tanto pela população costeira como pelos demais setores da economia, principalmente o setor portuário e ocupação urbana. A influência antrópica sobre esta região, em virtude de sua riqueza natural, associada às mudanças climáticas, podem alterar a dinâmica das forçantes que atuam sobre a área, consequentemente, os processos que atuam sobre a zona costeira. O objetivo desse artigo foi trazer ao público informações da Zona Costeira do Amapá de maneira que esses dados possam ser usados para melhor gerir essa importante área do estado. Assim, o conhecimento sobre os diversos aspectos da Zona Costeira Amapaense, bem como as suas características, em estudos publicados ao longo dos últimos anos, forneceu um compilado de informações a respeito da região que poderá futuramente servir como fonte de referência para o devido manejo dos recursos naturais, gestão e ordenamento territorial nessa área. Overview Of Coastal Zone of the State Of AmapáABSTRACTThe Amapaense Coastal Zone is an area with diverse environments and natural resources. To manage this space more efficiently, it is necessary to know its physical and socioeconomic characteristics, and the processes that act on the coastal zone. The purpose of this article was to bring information from the Amapá Coastal Zone to the public, in order to provide subsidies to environmental agencies that operate in the coastal zone of the state, so that this data can be used to better manage this area of the state. The Amapaense Coastal Zone stands out for its dynamism and productivity in the region, marked by the intense activity of coastal processes that constantly modify the region; the performance of erosive and depositional processes in determining the current configuration of the coastal plain; the influence of the Amazon River on sediment transport and deposition along the coastline and on the consolidation of vegetation; the performance of mangroves as a place of refuge and feeding aquatic species; and the rich biodiversity of the Coastal Zone related to climatic conditions and the phenomenon of speciation in the tropics. These factors make the Amapá Coastal Zone an explored region, both by the coastal population with extractive activities and by the sectors of the economy such as ports and services related to urban occupations. With this article we hope to provide a compilation of information about the region that may in the future serve as a reference source for the proper management of natural resources, management and territorial ordering in this area as well as a baseline for further research.

“…The Barreiras Group is made up of sandy-clayey sediments, poorly consolidated, with variegated coloring, with lateritized and kaolinic levels. These sediments discordantly cover not only the crystalline basement rocks, but also the sediments of the meso-cenozoic coastal basins (Demattê et al, 2012). The genesis of this formation seems to be anastomous fluvial, passing to the top, to a meandering fluvial system, and according to the variability of sediments and relief, the soils developed on these materials are associations of Latossolos (Ferralsols), Argissolos (Acrisols) and Espodossolos (Podzols) (Assunção et al, 2018;Andrade et al, 2022).…”

“…The detritus fluvial-lagoon sediments constitute the quaternary unit with the largest area of occurrence in the metropolitan region of Recife, being composed of fine sands, silts, clays, diatoms and peat sediments. The mangrove sediments are predominantly made up of clays, silts, fine sands, silica carapaces of diatoms, sponges of spongiaries, organic remains and shells (Demattê et al, 2012;Teramoto et al, 2021;Andrade et al, 2022).…”

In the Prata watershed there are units corresponding to the Pleistocene Terraces and the Fluvium-Lagoon Sediments. This watershed is inserted almost entirely in the area of plateaus (Tabuleiros) with altitudes of 10 to 100 meters, and in areas with altitudes of 2 to 10 meters in the area of floodplains and fluvio-lagoon terraces. The present work aimed to characterize and classify soils in the Brazilian Soil Classification System -SiBCS and correlate them with the IUSS Working Group WRB-FAO (in parentheses), besides evidence some soil-landscape relations, that occur in Pleistocene terraces and fluviumlagoon sediments in the Prata watershed, located in the ecological reserve of Dois Irmãos State Park in Recife -PE, Brazil. Soil samples were used to perform physical, chemical and mineralogical analysis in laboratory. Watershed delimitation, Digital Elevation Model (DEM), slope map, soil map and slope x soil map were obtained and studied. The soils are quite acidic and have a very low natural fertility, with the Latossolos (Ferralsols) predominating in the landscape. The silt and clay fractions of the studied Argissolos (Acrisols) and Latossolos (Ferralsols) presented quartz and kaolinite as the main component. In the profile of Neossolo Quartzarênico (Arenosols) only quartz was identified as a component of the silt and clay fractions. The kaolinitic mineralogy of the clay fraction is consistent with the environment of its formation, that is, hot and humid. There is no relationship between the colors of soils and their exposure to the sun on the slopes where they occur. The occurrence of a sandy and whitish horizon between the litter and the A horizon, is not foreseen in the norms and criteria adopted in the Brazilian Soil Classification System -SiBCS.
