Two terrestrial records of rapid climatic change during the glacial–Holocene transition (14,000– 9,000 calendar years B.P.) from Europe

Two independent multidisciplinary studies of climatic change during the glacial–Holocene transition (ca. 14,000–9,000 calendar yr B.P.) from Norway and Switzerland have assessed organism responses to the rapid climatic changes and made quantitative temperature reconstructions with modern calibration data sets (transfer functions). Chronology at Kråkenes, western Norway, was derived from calibration of a high-resolution series of 14C dates. Chronologies at Gerzensee and Leysin, Switzerland, were derived by comparison of δ18O in lake carbonates with the δ18O record from the Greenland Ice Core Project. Both studies demonstrate the sensitivity of terrestrial and aquatic organisms to rapid temperature changes and their value for quantitative reconstruction of the magnitudes and rates of the climatic changes. The rates in these two terrestrial records are comparable to those in Greenland ice cores, but the actual temperatures inferred apply to the terrestrial environments of the two regions.

Uso de Google Calendar para la coordinación entre asignaturas del Grado en Ingeniería Química

Uno de los aspectos peor valorados por los estudiantes de las nuevas titulaciones de grado es la coordinación entre asignaturas del mismo curso en cuanto a la distribución de controles y otro tipo de pruebas objetivas a lo largo del cuatrimestre, que afecta a la carga de trabajo no presencial en determinados momentos. En la guía docente de cada asignatura aparece la información sobre las pruebas a realizar dentro de un cronograma aproximado por semanas, y está disponible antes del comienzo del curso. Sin embargo, esa distribución puede variar ligeramente una vez empezado el curso debido a diversos motivos, y no se dispone de la información para todas las asignaturas del cuatrimestre en un mismo documento, lo que facilitaría su visualización. En este trabajo se propone el uso de la herramienta Google Calendar con el objetivo de tener un mayor control de este aspecto y poder detectar y corregir conflictos que puedan surgir, aplicándolo al Grado en Ingeniería Química.
