Swath sonar bathymetry during POLARSTERN cruise ANT-XXVI/2 (PS75) with links to multibeam raw data files

Multibeam data were collected during R/V Polarstern cruise ANT-XXVI/2 along track lines of about 9,270 NM total length along transits, survey profiles and during stationary work. Departing in Punta Arenas the ship headed for its first main working area, the Eltanin Impact Area. In the following the ship's track crosses Pacific Antarctic Ridge and the corresponding fracture zones several times before arriving in Wellington. The refraction correction was achieved utilizing CTD profiles or by the system's own cross fan calibration. The quality of data might be reduced during bad weather periods or adverse sea ice conditions. The dataset contains raw data that are not processed and thus may contain errors and blunders in depth and position.

Democratizing Indonesia: Reformasi Period in Historical Perspective

Introduction : Triggered by the Asian currency crisis, Indonesia plunged into the times of violent change. With the downfall of the long-standing Soeharto rule in May 1998, changes of　the state order started with great magnitude and rapidity under a new banner of　“reformasi” (reform). What changes have occurred in this reformasi period? What do　these changes signify? To answer these questions, it would be better to have a certain　yardstick to allow us comparison. One possibility is to use a yardstick of history. What　picture will emerge if we see the current array of changes in long-term historical　perspectives is a main question of this paper. This paper intends to provide a bird’s-eye picture illustrating where in the Indonesian history the current restructuring of the state order is located. Rather than focusing on a specific area, I here attempt to broaden our outlook on Indonesia’s political, economic and social arenas in order to identify what are happening in these arenas, how they are mutually related, and what those events signify in the Indonesia’s historical context.

Understanding long-term hunting statistics: the case of Spain (1972-2007)

Hunting is assuming a growing role in the current European forestry and agroforestry landscape. However, consistent statistical sources that provide quantitative information for policy-making, planning and management of game resources are often lacking. In addition, in many instances statistical information can be used without sufficient evaluation or criticism. Recently, the European Commission has declared the importance of high quality hunting statistics and the need to set up a common scheme in Europe for their collection, interpretation and proper use. This work aims to contribute to this current debate on hunting statistics in Europe by exploring data from the last 35 years of Spanish hunting statistics. The analysis focuses on the three major pillars underpinning hunting activity: hunters, hunting grounds and game animals. First, the study aims to provide a better understanding of official hunting statistics for use by researchers, game managers and other potential users. Second, the study highlights the major strengths and weaknesses of the statistical information that was collected. The results of the analysis indicate that official hunting statistics can be incomplete, dispersed and not always homogeneous over a long period of time. This is an issue of which one should be aware when using official hunting data for scientific or technical work. To improve statistical deficiencies associated with hunting data in Spain, our main suggestion is the adoption of a common protocol on data collection to which different regions agree. This protocol should be in accordance with future European hunting statistics and based on robust and well-informed data collection methods. Also it should expand the range of biological, ecological and economic concepts currently included to take account of the profound transformations experienced by the hunting sector in recent years. As much as possible, any future changes in the selection of hunting statistics should allow for comparisons between new variables with the previous ones.

Las tobas cuaternarias del río Añamaza (provincia de Soria, Cordillera Ibérica): aproximación cronológica

High-gradient, stepped fluvial tufa systems with dammed areas existed in the River Añamaza valley (NW Iberian Ranges, Spain) during Quaternary times. Single deposits range from a few meters to about 70 m thick, in which prograding-aggrading wedges separated by erosional surfaces exist. Several episodes of tufa formation have been distinguished by means of U-series, Amino-acid racemization and radiocarbon techniques. These correlate to MIS 8, 7, 5 and 1. The presence of MIS 9 is uncertain, as chronological data may also correspond to older stages. Most tufas in this area formed in MIS 5. Distinct tufa episodes can also be distinguished in the Holocene. These are the first chronological data presented for one of the northernmost Quaternary tufa systems in the Iberian Ranges.
