During recent years, several eutrophication processes and subsequent environmental crises have occurred in Mar Menor, the largest hypersaline coastal lagoon Western Mediterranean Sea. In this study, Landsat-8 Sentinel-2 satellites are jointly used to examine evolution of main water quality descriptors during latest ecological crisis 2021, resulting an important loss benthic vegetation unusual mortality events affecting different aquatic species. Several field campaigns were carried out...
Central Chile is heavily exploited for mineral and water resources, with agriculture large urban populations all creating intensive landscape use. Few records of past environmental climate change are available that afford a broader context. To aid in this assessment, we present 700-year reconstruction from Laguna del Maule (LdM) the high Andes central based on sedimentological, geochemical, diatom pollen analyses. The age model 210 Pb/ 137 Cs 14 C dating tied into known volcanic eruptions....
ABSTRACT We present a 7‐ka environmental reconstruction based on sedimentological and geochemical data from Lago Vichuquén, coastal eutrophic lake in central Chile (34°48′S, 72°03′ W, 4 m a.s.l.). A relatively shallow restricted marine environment with low productivity, high detrital input dominant anoxic conditions the Vichuquén Basin occurred 7.0 to 6.5 cal ka BP. Rapid onset of Holocene transgression at BP favoured deeper more biologically productive environments that existed until 2.8...
Abstract Human activities have profoundly altered the global nutrient cycle through Land Use and Cover Changes (LUCCs) since industrial revolution especially during Great Acceleration (1950 CE). Yet, impact of such on terrestrial aquatic ecosystems above their ecological baselines are not well known, when considering response these systems to intensity LUCCs cycles. Here, we used a multiproxy approach (sedimentological, geochemical isotopic analyses, historical records, climate data,...
There is a current interest in the study of geochemical behavior rare earth elements (REE) aquatic systems since their identification as potential microcontaminants natural waters. In this context, here we report concentrations and patterns dissolved REE (dREE) waters Gulf Cádiz (GoC) its major estuaries (Guadiana, Tinto-Odiel Guadalquivir). Contamination area by metals has been extensively reported, linked to acid-mine inputs resulting from mineralization Iberian Pyrite Belt, discharged...
Abstract. Late Quaternary volcanic basins are active landscapes from which detailed archives of past climate and seismic activity can be obtained. A multidisciplinary study performed on a transect sediment cores was used to reconstruct the depositional evolution high-elevation Laguna del Maule (LdM) (36∘ S, 2180 m a.s.l., Chilean Andes). The recovered 5 composite sequence includes two thick turbidite units (LT1 LT2) numerous tephra layers (23 ash 6 lapilli). We produced an age model based...
Metal(oid)s concentrations have been quantified in plastic pieces collected from four beaches located the Mediterranean coast of Spain with different characteristics (i.e. anthropogenic pressure, zone). content was also related to selected criteria color, degradation status, polymer). The elements were mean sampled plastics following order: Fe > Mg Zn Mn Pb Sr As Cu Cr Ni Cd Co. Moreover, black, brown, PUR, PS, and coastal line concentrated higher metal(oid)s levels. Local sampling...
The levels of metals in the waters Mar Menor lagoon are higher southern than northern zone both dissolved (As: 1.78 μg L-1 north vs 1.86 south; Cd: 0.020 0.055 L-1; Pb: 0. 686 2.714 Zn: 3.06 10.2 L-1) as particulate fraction 13.6 g-1 27.3 0.510 2.11 g-1; 146 575 266 729 g-1). This difference is associated to influence historical and recent inputs from Sierra Minera Cartagena -La Unión located south lagoon. Strong winds cause sediment resuspension this shallow lagoon, increasing metal...
The Holocene palaeoclimatic history of the Galician continental shelf has been investigated through analyses diatom remains, other siliceous compounds, biogenic silica (BSi) and metals content in a multiproxy approach to gravity core recovered from Galicia Mud Patch, NW Iberian Peninsula, covering last 5000 years. Downcore changes assemblages composition abundance reflect production related long-/short-term variations climate, regional oceanography, upwelling strength river influx off coast...
