Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain)

Hydro-physical characterization of contrasting soils in a semiarid zone of the Ebro river valley (NE Spain)

Alluvial sinkholes over gypsum in the Ebro basin ( Spain ) : genesis and environmental impact

The Ebro Basin is located in the northeast of Spain. Its central part is filled with gypsum and carbonate deposits of Neogene age. Quaternary sediments overlie the Tertiary layers. Alluvial sinkholes have developed in this region, causing high economic losses. From the study of aerial photographs, from the compilation of historical cases of collapse and from data on the lithological characteris...

Picocyanobacteria distribution in the Ebro Estuary (Spain)

The stratified estuary of the Ebro River is located on the Mediterranean coast of Spain. From samples obtained in 6 sampling campaigns between July 1999 and February 2000 from the last 18 km of Ebro River, the abundance of picocyanobacteria was estimated by epifluorescence microscopy. The abundance of picocyanobacteria reached 93.7 x106 cells L–1 in the river mouth (station R1) below the surfac...

GEOLOGICAL NOTE Global Aridity during the Early Miocene? A Terrestrial Paleoclimate Record from the Ebro Basin, Spain

Paleosols are an important tool in the paleoclimatic and paleoenvironmental interpretation of continental deposits and can provide a high-resolution proxy for paleoclimate. Results from geochemical climofunctions applied to Early Miocene strata exposed in the Ebro Basin, Spain, demonstrate that mean annual precipitation was the dominant control on paleosol type and indicate that the paleoclimat...

the effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance

this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
