An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.

Adult male southern elephant seals instrumented in 2000 on King George Island (n = 13), travelled both to the north (doi:10.1594/PANGAEA.231580, doi:10.1594/PANGAEA.231585) and to the east (doi:10.1594/PANGAEA.231571, doi:10.1594/PANGAEA.231579, doi:10.1594/PANGAEA.261708, doi:10.1594/PANGAEA.261709, doi:10.1594/PANGAEA.261710, doi:10.1594/PANGAEA.261711) of the Antarctic Peninsula. Five males (doi:10.1594/PANGAEA.231571, doi:10.1594/PANGAEA.231579, doi:10.1594/PANGAEA.231580, doi:10.1594/PANGAEA.261710, doi:10.1594/PANGAEA.231585) remained within 500 km of the island and focusing movements in the Bransfield Strait and around the Antarctic Peninsula. Sea-surface temperatures encountered by these animals showed little variation and they seemed to move about irrespective of sea ice cover, but frequented areas of shallow bathymetry. Three males (doi:10.1594/PANGAEA.261708, doi:10.1594/PANGAEA.261709, doi:10.1594/PANGAEA.261711) moved as far as 75°S to the east of the peninsula, into the Weddell Sea, with maximum distances of more than 1500 km from King George Island. They travelled into the Weddell Sea along the western continental shelf break until they reached the region of the Filchner Trough outflow. Here the bathymetry consists of canyons and ridges which support the intensive mixing between the warm saline waters of the Weddell Gyre and the very cold outflow waters with Ice Shelf water ingredients at the Antarctic Slope Front. Another five data sets were shorter then 40 days, and excluded from analyses (doi:10.1594/PANGAEA.231568, doi:10.1594/PANGAEA.231576, doi:10.1594/PANGAEA.231572, doi:10.1594/PANGAEA.231577, doi:10.1594/PANGAEA.264710). A computer animation was developed to visualize the animal movements in relation to the extent and concentration of sea ice (doi:10.1594/PANGAEA.509404). The need for re-instrumentation of adult males from King George Island is highlighted to investigate whether males continue to travel to similar areas and to obtain higher resolution data.

El debate acerca de la existencia, cronología y factores de una "revolución agrícola" que precede y se relaciona con la "revolución industrial" tiene larga data. Los temas sustantivos de este debate conservan una importancia central para comprender el desarrollo tanto de la agricultura como de la economía inglesas en los siglos que median de 1500 a 1850. A lo largo del mismo se han configurado una versión tradicional y otra revisionista. Resulta posible a esta altura, realizar una confrontación de ambas interpretaciones por medio de la obra de dos autores importantes, Marc Overton y Robert C. Allen.
